Diabetes

The known reduction in the risk of type 2 diabetes associated with adoption of the Mediterranean diet appears specifically attributed to its beneficial effects on some key factors, a new study published online in JAMA Network Open reveals.

While a reduction in body mass index may be somewhat obvious, other mechanisms include beneficial effects on insulin resistance, lipoprotein metabolism, and inflammation.

However, the diet’s antidiabetes effect does not appear to extend to people whose weight is considered healthy (BMI under 25 kg/m²), according to the findings.

“It is striking to see in these U.S. women how strong the long-term antidiabetic properties of a Mediterranean-type dietary pattern are,” senior author Samia Mora, MD, of the Center for Lipid Metabolomics, Brigham and Women’s Hospital, Harvard Medical School, Boston, said in an interview.

“While it was known that the Mediterranean diet has many health benefits in particular on metabolism and inflammation, it was not previously known which of these biological pathways may be contributing to the lower risk of diabetes and to what magnitude.

“Our findings support the idea that by improving their diet, people can improve their future risk of type 2 diabetes, particularly if they are overweight or have obesity,” she added.

“And it’s important to note that many of these changes don’t happen right away. While metabolism can change over a short period of time, our study indicates that there are longer term changes happening that may provide protection over decades.”
 

Mediterranean diet reduced diabetes risk in those with BMI ≥ 25 kg/m²

The Mediterranean diet, with an emphasis on healthy olive oil as the predominant source of oil, favors fruits, vegetables, legumes, nuts, seeds, fish, and dairy products, while limiting intake of red and processed meats as well as sweets.

The diet has been linked to as much as a 25%-30% reduction in the risk of diabetes in previous observational studies.

To investigate the precise mechanisms that underlie the prevention of diabetes, lead author Shafqat Ahmad, PhD, also of Harvard, and colleagues examined data from 25,317 healthy women participating in the Women’s Health Study who had baseline assessments between September 1992 and May 1995. They were a mean age of 52.9 years at baseline.

Over the course of the study, 2,307 participants developed type 2 diabetes.

With a mean follow-up of 19.8 years, those who had the highest self-reported adherence to the Mediterranean diet (a score ≥ 6 on a scale of 0-6) at baseline, had as much as a 30% lower risk of developing type 2 diabetes after multivariate adjustments, compared to those with a lower Mediterranean diet score (a score ≤ 3; hazard ratio, 0.70).

The diabetes-related biomarkers that contributed the most to the reduced risk were insulin resistance, accounting for 65% of the reduction, followed by BMI (55.5%), high-density lipoprotein measures (53%), and inflammation (52.5%).

Other factors, though to a lesser degree, included branched-chain amino acids (34.5%), very low-density lipoprotein measures (32.0%), low-density lipoprotein measures (31.0%), blood pressure (29.0%), and apolipoproteins (23.5%).

Differences in hemoglobin A1c levels had a limited effect on the risk (2%).

Notably, a subgroup analysis looking at effects of the diet according to baseline BMI showed the reductions in type 2 diabetes associated with higher intake of the Mediterranean diet extended only to those with an above normal weight (BMI ≥ 25 kg/m²).

Dr. Mora noted that, as this was not a prespecified analysis, these findings should be viewed as hypothesis-generating, but are consistent with the well-known increase in diabetes risk seen with a higher BMI.

“[The finding] fits with the biology and pathogenesis of type 2 diabetes that is driven in large part by excess weight, in particular for visceral adiposity and its resulting metabolic dysregulation and inflammation,” she said.

“We know from other studies, such as the Nurses’ Health Study, that the risk for type 2 diabetes in women increases even at BMI levels below 25 kg/m², but the risk goes up exponentially at around a BMI of 25 and higher.”

Strong role of insulin resistance a surprise

The strong role of insulin resistance was a surprise, Dr. Mora added.

“We were surprised that insulin resistance, measured by a simple blood biomarker, would have the strongest mediating effect – even stronger than BMI – for the Mediterranean diet on risk of diabetes,” she noted.

“This could represent an opportunity to intervene earlier and more intensively on improving insulin resistance through dietary approaches such as the Mediterranean diet, especially [because] insulin resistance can precede by years and decades the overt hyperglycemia and clinical diagnosis of diabetes.”

Yet another surprise was that A1c had no substantial mediating effect on the reduction of diabetes risk with the Mediterranean diet.

“This could suggest that the cat is out of the bag by the time the A1c rises,” Dr. Mora observed.

A study limitation is that the Women’s Health Study consisted of well-educated U.S. women who were health professionals and predominantly White, so the results may not be generalizable to men or individuals of other races or ethnicities.

In addition, BMI was self-reported and participants were not uniformly screened for diabetes, therefore surveillance bias could be possible.

However, the findings suggest that “even a small increase in adherence to the Mediterranean diet has substantial benefits over many years in preventing diabetes, among many other health benefits such as lowering insulin resistance and inflammation, improving lipid metabolism, and lowering blood pressure,” Mora said.

“And of course, the more the adherence, the more the benefit.” 

The study received support through grants from the National Institutes of Health, the National Heart, Lung, and Blood Institute, the National Institute of Diabetes and Digestive and Kidney Diseases, the American Heart Association, and the Molino Family Trust.

Women with type 2 diabetes who take metformin during pregnancy to control their blood glucose levels experience a range of benefits, including reduced weight gain, reduced insulin doses, and fewer large-for-gestational-age babies, suggest the results of a randomized controlled trial.

However, the drug was associated with an increased risk of small-for-gestational-age babies, which poses the question as to risk versus benefit of metformin on the health of offspring.

“Better understanding of the short- and long-term implications of these effects on infants will be important to properly advise patients with type 2 diabetes contemplating use of metformin during pregnancy,” said lead author Denice S. Feig, MD, Mount Sinai Hospital, Toronto.

The research was presented at the Diabetes UK Professional Conference: Online Series on Nov. 17 and recently published in The Lancet Diabetes & Endocrinology.

Summing up, Dr. Feig said that, on balance, she would be inclined to give metformin to most pregnant women with type 2 diabetes, perhaps with the exception of those who may have risk factors for small-for-gestational-age babies; for example, women who’ve had intrauterine growth restriction, who are smokers, and have significant renal disease, or have a lower body mass index.
 

Increased prevalence of type 2 diabetes in pregnancy

Dr. Feig said that across the developed world there have been huge increases in the prevalence of type 2 diabetes in pregnancy in recent years.

Insulin is the standard treatment for the management of type 2 diabetes in pregnancy, but these women have marked insulin resistance that worsens in pregnancy, which means their insulin requirements increase, leading to weight gain, painful injections, high cost, and noncompliance.

So despite treatment with insulin, these women continue to face increased rates of adverse maternal and fetal outcomes.

And although metformin is increasingly being used in women with type 2 diabetes during pregnancy, there is a scarcity of data on the benefits and harms of metformin use on pregnancy outcomes in these women.

The MiTy trial was therefore undertaken to determine whether metformin could improve outcomes.

The team recruited 502 women from 29 sites in Canada and Australia who had type 2 diabetes prior to pregnancy or were diagnosed during pregnancy, before 20 weeks’ gestation. The women were randomized to metformin 1 g twice daily or placebo, in addition to their usual insulin regimen, at between 6 and 28 weeks’ gestation.

Type 2 diabetes was diagnosed prior to pregnancy in 83% of women in the metformin group and in 90% of those assigned to placebo. The mean hemoglobin A1c level at randomization was 47 mmol/mol (6.5%) in both groups.

The average maternal age at baseline was approximately 35 years and mean gestational age at randomization was 16 weeks. Mean prepregnancy BMI was approximately 34 kg/m².

Of note, only 30% were of European ethnicity.
 

Less weight gain, lower A1c, less insulin needed with metformin

Dr. Feig reported that there was no significant difference between the treatment groups in terms of the proportion of women with the composite primary outcome of pregnancy loss, preterm birth, birth injury, respiratory distress, neonatal hypoglycemia, or admission to neonatal intensive care lasting more than 24 hours (P = 0.86).

However, women in the metformin group had significantly less overall weight gain during pregnancy than did those in the placebo group, at –1.8 kg (P < .0001).

They also had a significantly lower last A1c level in pregnancy, at 41 mmol/mol (5.9%) versus 43.2 mmol/mol (6.1%) in those given placebo (P = .015), and required fewer insulin doses, at 1.1 versus 1.5 units/kg/day (P < .0001), which translated to a reduction of almost 44 units/day.

Women given metformin were also less likely to require Cesarean section delivery, at 53.4% versus 62.7% in the placebo group (P = .03), although there was no difference between groups in terms of gestational hypertension or preeclampsia.

The most common adverse events were gastrointestinal complications, which occurred in 27.3% of women in the metformin group and 22.3% of those given placebo.

There were no significant differences between the metformin and placebo groups in rates of pregnancy loss (P = .81), preterm birth (P = .16), birth injury (P = .37), respiratory distress (P = .49), and congenital anomalies (P = .16).
 

Average birth weight lower with metformin

However, Dr. Feig showed that the average birth weight was lower for offspring of women given metformin than those assigned to placebo, at 3.2 kg (7.05 lb) versus 3.4 kg (7.4 lb) (P = .002).

Women given metformin were also less likely to have a baby with a birth weight of 4 kg (8.8 lb) or more, at 12.1% versus 19.2%, or a relative risk of 0.65 (P = .046), and a baby that was extremely large for gestational age, at 8.6% versus 14.8%, or a relative risk of 0.58 (P = .046).

But of concern, metformin was associated with an increased risk of small-for-gestational-age babies, at 12.9% versus 6.6% with placebo, or a relative risk of 1.96 (P = .03).

Dr. Feig suggested that this may be due to a direct effect of metformin “because as we know metformin inhibits the mTOR pathway,” which is a “primary nutrient sensor in the placenta” and could “attenuate nutrient flux and fetal growth.”

She said it is not clear whether the small-for-gestational-age babies were “healthy or unhealthy.”

To investigate further, the team has launched the MiTy Kids study, which will follow the offspring in the MiTy trial to determine whether metformin during pregnancy is associated with a reduction in adiposity and improvement in insulin resistance in the babies at 2 years of age.
 

Who should be given metformin?

During the discussion, Helen R. Murphy, MD, PhD, Norwich Medical School, University of East Anglia, England, asked whether Dr. Feig would recommend continuing metformin in pregnancy if it was started preconception for fertility issues rather than diabetes.

She replied: “If they don’t have diabetes and it’s simply for PCOS [polycystic ovary syndrome], then I have either stopped it as soon as they got pregnant or sometimes continued it through the first trimester, and then stopped.

“If the person has diabetes, however, I think given this work, for most people I would continue it,” she said.

The study was funded by the Canadian Institutes of Health Research, Lunenfeld-Tanenbaum Research Institute, and the University of Toronto. The authors have reported no relevant financial relationships.

They also had a significantly lower last A1c level in pregnancy, at 41 mmol/mol (5.9%) versus 43.2 mmol/mol (6.1%) in those given placebo (P = .015), and required fewer insulin doses, at 1.1 versus 1.5 units/kg/day (P < .0001), which translated to a reduction of almost 44 units/day.

Women given metformin were also less likely to require Cesarean section delivery, at 53.4% versus 62.7% in the placebo group (P = .03), although there was no difference between groups in terms of gestational hypertension or preeclampsia.

The most common adverse events were gastrointestinal complications, which occurred in 27.3% of women in the metformin group and 22.3% of those given placebo.

There were no significant differences between the metformin and placebo groups in rates of pregnancy loss (P = .81), preterm birth (P = .16), birth injury (P = .37), respiratory distress (P = .49), and congenital anomalies (P = .16).
 

Average birth weight lower with metformin

However, Dr. Feig showed that the average birth weight was lower for offspring of women given metformin than those assigned to placebo, at 3.2 kg (7.05 lb) versus 3.4 kg (7.4 lb) (P = .002).

Women given metformin were also less likely to have a baby with a birth weight of 4 kg (8.8 lb) or more, at 12.1% versus 19.2%, or a relative risk of 0.65 (P = .046), and a baby that was extremely large for gestational age, at 8.6% versus 14.8%, or a relative risk of 0.58 (P = .046).

But of concern, metformin was associated with an increased risk of small-for-gestational-age babies, at 12.9% versus 6.6% with placebo, or a relative risk of 1.96 (P = .03).

Dr. Feig suggested that this may be due to a direct effect of metformin “because as we know metformin inhibits the mTOR pathway,” which is a “primary nutrient sensor in the placenta” and could “attenuate nutrient flux and fetal growth.”

She said it is not clear whether the small-for-gestational-age babies were “healthy or unhealthy.”

To investigate further, the team has launched the MiTy Kids study, which will follow the offspring in the MiTy trial to determine whether metformin during pregnancy is associated with a reduction in adiposity and improvement in insulin resistance in the babies at 2 years of age.
 

Who should be given metformin?

During the discussion, Helen R. Murphy, MD, PhD, Norwich Medical School, University of East Anglia, England, asked whether Dr. Feig would recommend continuing metformin in pregnancy if it was started preconception for fertility issues rather than diabetes.

She replied: “If they don’t have diabetes and it’s simply for PCOS [polycystic ovary syndrome], then I have either stopped it as soon as they got pregnant or sometimes continued it through the first trimester, and then stopped.

“If the person has diabetes, however, I think given this work, for most people I would continue it,” she said.

The study was funded by the Canadian Institutes of Health Research, Lunenfeld-Tanenbaum Research Institute, and the University of Toronto. The authors have reported no relevant financial relationships.

The human monoclonal antibody golimumab (Simponi) preserved endogenous insulin secretion in patients with new-onset type 1 diabetes and reduced their exogenous insulin requirements at 1 year, newly published phase 2 data indicate.

Results from the multicenter, double-blind, placebo-controlled trial were first reported as a poster at the virtual American Diabetes Association 80th Scientific Sessions in June. They were published online Nov. 18 in the New England Journal of Medicine.

In the 52-week study of 84 children and adults with new-onset type 1 diabetes, those given golimumab injections every 2 weeks had significantly higher levels of C-peptide, a marker of insulin secretion, and required less injected or infused insulin than did those who received placebo injections. There were no treatment-associated serious adverse events.

Golimumab is a human monoclonal antibody specific for tumor necrosis factor–alpha. It is approved for the treatment of several autoimmune diseases, including rheumatoid arthritis and ulcerative colitis, in the United States, Europe, and elsewhere.
 

An intermediate step toward a cure

Although none of the patients were able to stop taking insulin entirely, the results have important clinical implications, lead author Teresa Quattrin, MD, said in an interview.

“People want a cure, but the fact is, a cure is not available yet. So, this is an intermediate step towards a cure.... There are advantages to being on a small insulin dose,” including lower rates of hypoglycemia and maintenance of intraportal insulin, said Dr. Quattrin, of the State University of New York at Buffalo.

But in an accompanying editorial, Domenico Accili, MD, points to potential risks from immunotherapy and from attempting additional interventions at an “emotionally fraught” time when patients and families are coping with the new diabetes diagnosis.

He said of golimumab, “the effect is actually very small. ... There’s nothing wrong in and of itself with improving those outcomes. I just wouldn’t assign them as game changers.”

If this or a similar immunotherapeutic intervention were approved for this indication, “I would tell patients it exists and let them make the decision whether they want to try it. I wouldn’t say you must try it,” said Dr. Accili, of the Columbia University Diabetes and Endocrinology Research Center, New York.
 

With golimumab, higher C-peptide, lower insulin requirement

Of the 84 patients, who ranged in age from 6 to 21 years, 56 were randomly assigned within 100 days of being diagnosed with type 1 diabetes to receive golimumab, and 28 were assigned to receive placebo injections, given every 2 weeks.

The drug resulted in lower insulin use (0.51U/Kg per day vs. 0.69 U/kg per day), and the increase in insulin use over 52 weeks was less with golimumab than with placebo (0.07 vs. 0.24 U/kg per day; P = .001).

The mean percent decrease of C-peptide production from baseline was 12% with golimumab versus 56% with placebo.

Although the mean number of overall hypoglycemic events was similar, the mean number of level 2 hypoglycemic events (<54 mg/dL) was 36% lower with golimumab (11.5 vs. 17.6). There were no severe cases of hypoglycemia in either group.

No severe or serious infections occurred in either group, although mild to moderate infections were reported in 71% with golimumab versus 61% with placebo. More patients in the golimumab group experienced a decrease in neutrophils (29% vs. 19%).
 

Immunotherapy: Which one, and when should it start?

These findings come on the heels of the 2019 landmark results with another monoclonal antibody, the investigational anti-CD3 teplizumab (PRV-031). Among patients at risk, a diagnosis of type 1 diabetes was delayed by 2 years, and continued benefit was seen at 3 years.

However, Dr. Quattrin said teplizumab is limited by the fact that it must be administered via a 14-day infusion, whereas golimumab can be injected by patients themselves at home.

Moreover, the phase 2 teplizumab study was conducted in people who had antibodies that placed them at high risk for type 1 diabetes, but those patients did not yet have the condition. They were identified because they had close relatives with type 1 diabetes and were enrolled in the federally funded TrialNet screening program.

Dr. Quattrin is now participating in an ongoing phase 3 study of teplizumab that involves patients newly diagnosed with type 1 diabetes.

A Janssen spokesperson said in an interview that the company isn’t planning to further develop golimumab for use in type 1 diabetes.

“Our focus is to apply insights from the phase 2 ... proof-of-concept study to progress what we believe are novel, immunologically targeted pipeline candidates in stage 2 disease or presymptomatic stages of type 1 diabetes, which is consistent with our mission to intercept and prevent type 1 diabetes,” the spokesperson said.

To identify more individuals at risk for type 1 diabetes beyond the close relatives of those who already have it, so as to be able to intervene at a presymptomatic stage, Janssen is organizing a public-private effort to advocate for routine population screening for type 1 diabetes–related autoantibodies.

Dr. Quattrin said: “Preserving some insulin is key. Having somebody with beta cell functioning still is an intermediate step to a cure and will make their life easier, and that’s what people should care about.”

Dr. Accili, who cofounded and leads a company working on a novel approach to type 1 diabetes treatment, writes in his editorial: “We should also be mindful that this treatment debate is first world–centric.

“Current treatments for type 1 diabetes require resources not readily available in most parts of the world, where something as simple as refrigeration of insulin can become a logistic nightmare. While combinations of [approaches] tailored to individual risk and potential benefits are likely to make inroads in clinical practice, the need for a simpler, safer, and equally effective alternative to insulin remains,” he wrote.

Dr. Quattrin is a researcher and consultant for Janssen and conducts clinical trials for Provention Bio, Opko, and Ascendis. Dr. Accili is founder and director of Forkhead Therapeutics.

Finerenone, the first nonsteroidal mineralocorticoid receptor antagonist to complete a phase 3 trial, showed cardiovascular benefits in patients with type 2 diabetes and chronic kidney disease, regardless of whether they entered the study with a history of cardiovascular disease, in follow-up analyses of the FIDELIO-DKD trial, which included 5,674 patients.

“Finerenone demonstrated benefits for primary and secondary cardiovascular disease protection,” said Gerasimos Filippatos, MD, at the American Heart Association scientific sessions. Finerenone treatment cut the rate of cardiovascular death, nonfatal MI or stroke, or heart failure hospitalization, when compared with placebo, by a relative 15% among patients with a history of cardiovascular disease (CVD), and by a relative 14% in patients without this history, differences that met a statistical test for consistency. But the absolute, drug-associated increments in benefit over placebo differed between the two CVD subgroups because of a sharp underlying difference in event rates.

In contrast, the analyses reported by Dr. Filippatos and associates from the FIDELIO-DKD study showed significant heterogeneity based on the presence or absence of CVD for the study’s primary endpoint, a composite renal metric that tallied the combined rate of death from renal causes, renal failure, or a sustained drop in estimated glomerular filtration rate of at least 40%. Researchers enrolled patients into FIDELIO-DKD based on having type 2 diabetes (T2D) and chronic kidney disease (CKD). The prevalence of a history of CVD was 46%.

Among patients with a history of CVD, the composite adverse CVD outcome occurred at a rate of 8.5/100 patient-years in patients on placebo and in 7.18/100 patients years among those on finerenone during a median of 2.6 years of follow-up, a 1.32/100–patient-year absolute between-group difference. Among patients in a primary prevention setting, incident CVD event rates during follow-up were roughly half that in the secondary prevention patients. The upshot was that, in the placebo group, the rate was 3.92/100 patient- years, and in those on finerenone was 3.43/100 patient-years, a 0.49/100–patient-year absolute difference.
 

CVD history produced heterogeneity for the primary endpoint

In the analysis that focused on the study’s primary, renal endpoint, among patients identified as having CVD at study entry, the outcome occurred at a rate of 9.06/100 patient-years in the placebo subgroup and at a rate of 6.6/100 patient years in those who received finerenone, a significant 30% relative risk reduction and an absolute between-group difference of 2.46/100 patient-years.

In contrast, among patients without a CVD history, the composite renal endpoint occurred at a rate of 9.1/100 patient-years in the placebo patients and 8.42/100 patient-years in those on finerenone, a 6% relative risk reduction that was not significant, and a 0.68/100–patient-year absolute difference. This disparity in the primary event rate between the two treatment arms reached statistical significance (P = .016), the investigators reported in the published version of the report in Circulation that simultaneously appeared online.

“The totality of evidence suggests that finerenone could be used in patients with T2D with or without a history of CVD,” explained Dr. Filippatos in an interview. “The P-interaction for the composite kidney outcome is significant, but it is not corrected for multiple testing; therefore, it might be a false-chance finding and must be interpreted cautiously.

Furthermore, in another prespecified kidney composite outcome the results were consistent in patients with and without a history of CVD. In sum, all the FIDELIO-DKD analyses so far are “suggestive of a beneficial effect in patients without a history of CVD.”

Despite these patients receiving guideline directed therapies, “there remains a high unmet medical need in patients with T2D and CKD,” added Dr. Filippatos, professor of cardiology at the University of Athens. “We use multiple treatments for patients with heart failure, and we should use the same mindset for treating patients with T2D and CKD. The costs of dialysis and kidney transplant are very high, so it is important to consider options that slow progression of CKD in these patients.”

In FIDELIO-DKD, virtually all patients were on background therapy with a renin-angiotensin-system (RAS) inhibitor, so the trial’s results suggest that treatment should at least involve dual therapy with finerenone and a RAS inhibitor. Fewer than 5% were on background therapy with a sodium-glucose cotransporter 2 (SGLT2) inhibitor, a drug class recently established as another key agent for treating CKD in patients with T2D, setting up the prospect for triple therapy, although this approach has not yet undergone prospective testing.

Combining RAS inhibition, finerenone, and an SGLT2 inhibitor is “potentially a marriage made in diabetes heaven,” commented Deepak L. Bhatt, MD, a professor of medicine at Harvard Medical School, Boston, who has not participated in finerenone studies.

Finerenone looks better for safety

Regardless of subgroup analyses based on history of CVD, the findings from all patients enrolled in FIDELIO-DKD were positive for the both the primary renal outcome and key secondary outcome of composite CVD events. In the total randomized cohort, treatment with finerenone on top of optimized treatment with an ACE inhibitor or angiotensin receptor blocker (RAS inhibition) led to a significant 18% relative risk reduction, compared with placebo, for the primary renal endpoint, and a significant 14% relative drop in the key secondary CVD outcome. Those results were published in October in the New England Journal of Medicine.

Finerenone treatment cut the rate of cardiovascular death, nonfatal MI or stroke, or heart failure hospitalization, when compared with placebo, by a relative 15% among patients with a history of cardiovascular disease (CVD), and by a relative 14% in patients without this history, differences that met a statistical test for consistency. But the absolute, drug-associated increments in benefit over placebo differed between the two CVD subgroups because of a sharp underlying difference in event rates.

In contrast, the analyses reported by Dr. Filippatos and associates from the FIDELIO-DKD study showed significant heterogeneity based on the presence or absence of CVD for the study’s primary endpoint, a composite renal metric that tallied the combined rate of death from renal causes, renal failure, or a sustained drop in estimated glomerular filtration rate of at least 40%. Researchers enrolled patients into FIDELIO-DKD based on having type 2 diabetes (T2D) and chronic kidney disease (CKD). The prevalence of a history of CVD was 46%.

Among patients with a history of CVD, the composite adverse CVD outcome occurred at a rate of 8.5/100 patient-years in patients on placebo and in 7.18/100 patients years among those on finerenone during a median of 2.6 years of follow-up, a 1.32/100–patient-year absolute between-group difference. Among patients in a primary prevention setting, incident CVD event rates during follow-up were roughly half that in the secondary prevention patients. The upshot was that, in the placebo group, the rate was 3.92/100 patient- years, and in those on finerenone was 3.43/100 patient-years, a 0.49/100–patient-year absolute difference.
 

CVD history produced heterogeneity for the primary endpoint

In the analysis that focused on the study’s primary, renal endpoint, among patients identified as having CVD at study entry, the outcome occurred at a rate of 9.06/100 patient-years in the placebo subgroup and at a rate of 6.6/100 patient years in those who received finerenone, a significant 30% relative risk reduction and an absolute between-group difference of 2.46/100 patient-years.

In contrast, among patients without a CVD history, the composite renal endpoint occurred at a rate of 9.1/100 patient-years in the placebo patients and 8.42/100 patient-years in those on finerenone, a 6% relative risk reduction that was not significant, and a 0.68/100–patient-year absolute difference. This disparity in the primary event rate between the two treatment arms reached statistical significance (P = .016), the investigators reported in the published version of the report in Circulation that simultaneously appeared online.

“The totality of evidence suggests that finerenone could be used in patients with T2D with or without a history of CVD,” explained Dr. Filippatos in an interview. “The P-interaction for the composite kidney outcome is significant, but it is not corrected for multiple testing; therefore, it might be a false-chance finding and must be interpreted cautiously.

Furthermore, in another prespecified kidney composite outcome the results were consistent in patients with and without a history of CVD. In sum, all the FIDELIO-DKD analyses so far are “suggestive of a beneficial effect in patients without a history of CVD.”

Despite these patients receiving guideline directed therapies, “there remains a high unmet medical need in patients with T2D and CKD,” added Dr. Filippatos, professor of cardiology at the University of Athens. “We use multiple treatments for patients with heart failure, and we should use the same mindset for treating patients with T2D and CKD. The costs of dialysis and kidney transplant are very high, so it is important to consider options that slow progression of CKD in these patients.”

In FIDELIO-DKD, virtually all patients were on background therapy with a renin-angiotensin-system (RAS) inhibitor, so the trial’s results suggest that treatment should at least involve dual therapy with finerenone and a RAS inhibitor. Fewer than 5% were on background therapy with a sodium-glucose cotransporter 2 (SGLT2) inhibitor, a drug class recently established as another key agent for treating CKD in patients with T2D, setting up the prospect for triple therapy, although this approach has not yet undergone prospective testing.

Combining RAS inhibition, finerenone, and an SGLT2 inhibitor is “potentially a marriage made in diabetes heaven,” commented Deepak L. Bhatt, MD, a professor of medicine at Harvard Medical School, Boston, who has not participated in finerenone studies.

Finerenone looks better for safety

Regardless of subgroup analyses based on history of CVD, the findings from all patients enrolled in FIDELIO-DKD were positive for the both the primary renal outcome and key secondary outcome of composite CVD events. In the total randomized cohort, treatment with finerenone on top of optimized treatment with an ACE inhibitor or angiotensin receptor blocker (RAS inhibition) led to a significant 18% relative risk reduction, compared with placebo, for the primary renal endpoint, and a significant 14% relative drop in the key secondary CVD outcome. Those results were published in October in the New England Journal of Medicine.

Health equity has been described as the opportunity for all persons to obtain their highest level of health possible.¹ Unfortunately, even with advances in technology and care practices, disparities persist in health care outcomes. Disparities in prevalence, prognosis, and outcomes still exist in diabetes management.² Non-Hispanic Black and/or Hispanic populations are more likely to have worse glycemic control,^3,4 to encounter more barriers in access to care,⁵ and to have higher levels of acute complications,⁴ and to use advanced technologies less frequently.⁴ Diabetes is one of the preexisting conditions that increase morbidity and mortality in COVID-19.^6,7 Unfortunately, adverse outcomes from COVID-19 also disproportionately impact a specific vulnerable population.^8,9 The urgent transition to managing diabetes remotely during the COVID-19 pandemic may exacerbate long-term inequities because some vulnerable patients might not have access to technology devices necessary for effective remote management.

Here, we describe how quality improvement (QI) tools and principles can be adapted into a framework for advancing health equity. Specifically, we describe a 10-step framework that may be applied in diabetes care management to achieve improvement, using a hypothetical example of increasing use of continuous glucose monitors (CGMs) among patients with type 1 diabetes mellitus.¹⁰ This framework was developed to address the literature gap on practical ways health care providers can address inequities using QI principles, and was implemented by 1 of the authors at a local public health department.¹¹ The framework’s iterative and comprehensive design makes it ideal for addressing inequities in chronic diseases like diabetes, which have multiple root causes with no easy solutions. The improvement program pilot received a national model practice award.^11,12

10-Step Framework

Step 1: Review program/project baseline data for existing disparities. Diabetes programs and routine QI processes encourage existing data review to determine how effective the current system is working and if the existing process has a predictable pattern.^13,14 Our equity-revised framework proposes a more in-depth review to stratify baseline data based on factors that might contribute to inequities, including race, age, income levels, ethnicity, language, sexual orientation, insurance type, and zip code. This process will identify patients not served or unfairly impacted due to socioeconomic factors. For example, using the hypothetical example of improving CGM use, a team completes a preliminary data review and determines that baseline CGM use is 30% in the clinic population. However, in a review to assess for disparities, they also identify that patients on public insurance have a significantly lower CGM uptake of only 15%.

Step 2: Build an equitable project team, including patients with lived experiences. Routine projects typically have clinicians, administrative staff, and analytic staff as members of their team. In a post-COVID-19 world, every team needs to learn directly from people impacted and share decision-making power. The traditional approach to receiving feedback has generally been to collect responses using surveys or focus groups. We propose that individuals/families who are disproportionately impacted be included as active members on QI teams. For example, in the hypothetical example of the CGM project, team members would include patients with type 1 diabetes who are on public insurance and their families.

Step 3: Develop equity-focused goals. The traditional program involves the development of aims that are SMART (specific, measurable, achievable, realistic, time-bound).¹⁵ The proposed framework encourages the inclusion of equity-revised goals (SMARTer) using insights from Steps 1 and 2. For example, your typical smart goal might be to increase the percentage of patients using CGM by 20% in 6 months, while a SMARTer goal would be to increase the proportion of patients using CGM by 20% and reduce the disparities among public and private insurance patients by 30% in 6 months.

Step 4: Identify inequitable processes/pathways. Traditional QI programs might use a process map or flow diagram to depict the current state of a process visually.¹⁶ For example, in Figure 1, the process map diagram depicts some differences in the process for patients with public insurance as opposed to those with private insurance. The framework also advocates for using visual tools like process maps to depict how there might be inequitable pathways in a system. Visually identifying inequitable processes/pathways can help a team see barriers, address challenges, and pilot innovative solutions.

Step 5: Identify how socioeconomic factors are contributing to the current outcome. A good understanding of factors that contribute to the problem is an essential part of finding fundamental solutions. The fishbone diagram¹⁶ is a visualization tool used to identify contributing factors. When investigating contributing factors, it is commonplace to identify factors that fit into 1 of 5 categories: people, process, place, product, and policies (5 Ps). An equity-focused process will include equity as a new major factor category, and the socioeconomic impacts that contribute to inequities will be brainstormed and visually represented. For example, in the hypothetical CGM improvement example, an equity contributing factor is extensive CGM application paperwork for patients on public insurance as compared to those on private insurance. Figure 2 shows equity integrated into a fishbone diagram.

Step 6: Brainstorm possible improvements. Potential improvement ideas for the hypothetical CGM example might include redesigning the existing workflow, piloting CGM educational classes, and using a CGM barrier assessment tool to identify and address barriers to adoption.

Step 7: Use the decision matrix with equity as a criterion to prioritize improvement ideas. Decision matrix¹⁵ is a great tool that is frequently used to help teams prioritize potential ideas. Project team members must decide what criteria are important in prioritizing ideas to implement. Common criteria include implementation cost, time, and resources, but in addition to the common criteria, the team can specify ”impact on equity” as one of their criteria, alongside other standard criteria like impact.

Step 8: Test one small change at a time. This step is consistent with other traditional improvement models using the Plan, Do, Study, Act (PDSA) model for improvement.¹⁷ During this phase, the team should make predictions on the expected impact of the intervention on outcomes. For example, in the hypothetical example, the team predicts that testing and expanding CGM classes will reduce disparities among public versus private health insurance users by 5% and increase overall CGM uptake by 10%.

Step 9: Measure and compare results with predictions to identify inequitable practices or consequences. After each test of change, the team should review the results, including implementation cost considerations, and compare them to the predictions in the earlier step. The team should also document the potential reasons why their predictions were correct or inaccurate, and whether there were any unforeseen outcomes from the intervention.

Step 10: Celebrate small wins and repeat the process. Making fundamental and equitable changes takes time. This framework aimed at undoing inequities, particularly those inequities that have been amplified by the COVID-19 pandemic, is iterative and ongoing.^18,19 Not every test of change will impact the outcome or reduce inequity, but over time, each change will impact the next, generating sustainable effects.

Conclusion

There are ongoing studies examining the adverse outcomes and potential health inequities for patients with diabetes impacted by COVID-19.²⁰ Health care providers need to plan for post-COVID-19 care, keeping in mind that the pandemic might worsen already existing health disparities in diabetes management.^3,4,21 This work will involve an intentional approach to address structural and systemic racism.²² Therefore, the work of building health equity solutions must be rooted in racial justice, economic equity, and equitable access to health care and education.

Initiatives like this are currently being funded through foundation grants as well as state and federal research or program grants. Regional and national payors, including the Centers for Medicare & Medicaid Services, are currently piloting long-term sustainable funding models through programs like accountable care organizations and the Accountable Health Communities Model.²³

Health systems can successfully address health equity and racial justice, using a framework as described above, to identify determinants of health, develop policies to expand access to care for the most vulnerable patients, distribute decision-making power, and train staff by naming structural racism as a driver of health inequities.

Study Overview

Objective. To assess whether dapagliflozin added to guideline-recommended therapies is effective and safe over the long-term to reduce the rate of renal and cardiovascular events in patients across multiple chronic kidney disease (CKD) stages, with and without type 2 diabetes.

Design. The Dapagliflozin and Prevention of Adverse Outcomes in CKD (DAPA-CKD) trial (NCT03036150) was a randomized, double-blind, parallel-group, placebo-controlled, multicenter event-driven, clinical trial sponsored by Astra-Zeneca. It was conducted at 386 sites in 21 countries from February 2, 2017, to June 12, 2020. A recruitment period of 24 months and a total study duration of 45 months were initially planned. The primary efficacy analysis was based on the intention-to-treat population. This was the first randomized controlled trial designed to assess the effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors on renal and cardiovascular outcomes in patients with CKD.

Setting and participants. This trial randomly assigned 4304 adult participants with CKD stages 2 to 4 (an estimated glomerular filtration rate [GFR] of 25 to 75 mL/min/1.73 m² of body-surface area) and elevated urinary albumin excretion (urinary albumin-to-creatinine ratio of 200 to 5000, measured in mg of albumin per g of creatinine) to receive dapagliflozin (10 mg once daily) or placebo. Exclusion criteria included type 1 diabetes, polycystic kidney disease, lupus nephritis, antineutrophil cytoplasmic antibody–associated vasculitis, recent immunosuppressive therapy for primary or secondary kidney disease, New York Heart Association class IV congestive heart failure, myocardial infarction, unstable angina, stroke or transient ischemic attacks, or recent coronary revascularization or valvular repair/replacement. All participants received a stable dose of renin–angiotensin system inhibitor for 4 weeks prior to screening, and the vast majority received a maximum tolerated dose at enrollment. Randomization was monitored to ensure that at least 30% of participants recruited did not have diabetes and that no more than 10% had stage 2 CKD. Participants were randomly assigned to receive dapagliflozin (n = 2152) or matching placebo (n = 2152) to ensure a 1:1 ratio of the 2 regimens. Dapagliflozin and placebo had identical appearance and administration schedules. All participants and trial personnel (except members of the independent data monitoring committee) were unaware of the trial-group assignments. After randomization, in-person study visits were conducted at 2 weeks, at 2, 4, and 8 months, and at 4-month intervals thereafter.

Main outcome measures. The primary outcome was a composite of the first occurrence of either a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes. Secondary outcomes, in hierarchical order, were: (1) the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes; (2) a composite cardiovascular outcome defined as hospitalization for heart failure or death from cardiovascular causes; and (3) death from any cause. All outcomes were assessed by time-to-event analyses.

Given the extensive prior experience with dapagliflozin, only selected adverse events were recorded. These included serious adverse events, adverse events resulting in the discontinuation of dapagliflozin or placebo, and adverse events of interest to dapagliflozin (eg, volume depletion symptoms, renal events, major hypoglycemia, fractures, diabetic ketoacidosis, events leading to higher risk of lower limb amputation, and lower limb amputations).

Main results. On March 26, 2020, the independent data monitoring committee recommended stopping the trial because of clear efficacy on the basis of 408 primary outcome events. The participants were 61.8 ± 12.1 years of age, and 1425 participants (33.1%) were female. The baseline mean estimated GFR was 43.1 ± 12.4 mL/min/1.73 m², the median urinary albumin-to-creatinine ratio was 949, and 2906 participants (67.5%) had type 2 diabetes. Over a median of 2.4 years, a primary outcome event occurred in 197 participants (9.2%) in the dapagliflozin group and 312 (14.5%) in the placebo group (hazard ratio [HR], 0.61; 95% confidence interval [CI], 0.51-0.72; P < 0.001). The number of participants who needed to be treated during the trial period to prevent 1 primary outcome event was 19 (95% CI, 15-27). The beneficial effect of dapagliflozin compared with placebo was consistent across all 8 prespecified subgroups (ie, age, sex, race, geographic region, type 2 diabetes, estimated GFR, urinary albumin-to-creatinine ratio, and systolic blood pressure) for the primary outcome. The effects of dapagliflozin were similar in participants with type 2 diabetes and in those without type 2 diabetes.

The incidence of each secondary outcome was similarly lower in the dapagliflozin-treated group than in the placebo group. The HR for the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes was 0.56 (95% CI, 0.45-0.68; P < 0.001), and the HR for the composite cardiovascular outcome of hospitalization for heart failure or death from cardiovascular causes was 0.71 (95% CI, 0.55-0.92; P = 0.009). Death occurred in 101 participants (4.7%) in the dapagliflozin group and 146 participants (6.8%) in the placebo group (HR, 0.69; 95% CI, 0.53-0.88; P = 0.004). The known safety profile of dapagliflozin was confirmed by the similar overall incidences of adverse events and serious adverse events in the dapagliflozin and placebo groups.

Conclusion. In patients with CKD, with or without type 2 diabetes, the risk of a composite of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes was significantly lowered by dapagliflozin treatment.

Commentary

Although SGLT2 inhibitors were designed to reduce plasma glucose and hemoglobin A1c (HbA1c) by increasing urinary glucose excretion in a non-insulin-dependent fashion, an increasing number of clinical trials have demonstrated their possible cardiovascular and renal benefits that extend beyond glycemic control. In 2008, the US Food and Drug Administration (FDA) issued a guidance recommending the evaluation of long-term cardiovascular outcomes prior to approval and commercialization of new antidiabetic therapies to ensure minimum cardiovascular risks following the discovery of cardiovascular safety issues associated with antidiabetic compounds, including rosiglitazone, after drug approval. No one foresaw that this recommendation would lead to the discovery of new classes of antidiabetic drugs (glucagon-like peptide 1 [GLP1] and SGLT2 inhibitors) that improve cardiovascular outcomes. A series of clinical trials of SGLT2 inhibitors, including empagliflozin,¹ canagliflozin,² and dapagliflozin,³ showed a reduction in cardiovascular death and hospitalization due to heart failure among patients with type 2 diabetes. Furthermore, a meta-analysis from 2019 found that SGLT2 inhibitors reduced the risk of a composite of cardiovascular death or hospitalization for heart failure by 23% and the risk of progression of kidney failure by 45% in patients with diabetes.⁴ Thus, the strong and consistent evidence from these large and well-designed outcome trials led the American Diabetes Association in its most recent guidelines to recommend adding SGLT2 inhibitors to metformin for the treatment of patients with type 2 diabetes with or at high risk of atherosclerotic cardiovascular disease, heart failure, or CKD, regardless of baseline HbA1c levels or HbA1c target.⁵ As a result of the compelling effects of SGLT2 inhibitors on cardiovascular outcomes in diabetic patients, as well as increasing evidence that these clinical effects were independent of glycemic control, several subsequent trials were conducted to evaluate whether this new class of drugs may improve clinical outcomes in nondiabetic patients.

The Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) was the first clinical trial to investigate the effect of SGLT2 inhibitors on cardiovascular disease in nondiabetic patients. Findings from DAPA-HF showed that dapagliflozin reduced the risk of worsening heart failure or death from cardiovascular causes, independent of the presence of underlying diabetes. This initial finding resonates with a growing body of evidence^6,7 that supports the use of SGLT2 inhibitors as an adjunctive therapy for heart failure in the absence of diabetes.

The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial showed that long-term administration of canagliflozin conferred cardiovascular, as well as renal, protection in patients with type 2 diabetes with CKD.⁸ Similar to the protective effects on heart failure, the renal benefits of SGLT2 inhibitors appeared to be independent of their blood glucose-lowering effects. Thus, these recent discoveries led to the design of the DAPA-CKD trial to further assess the long-term efficacy and safety of the SGLT2 inhibitor dapagliflozin in patients with CKD precipitated by causes other than type 2 diabetes. Although diabetes is the most common cause for CKD, it nonetheless only accounts for 40% of all CKD etiologies. To date, the only classes of medication that have been shown to slow a decline in kidney function in patients with diabetes are angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs). Given that CKD is an important contributor to illness, is associated with diminished quality of life and reduced life expectancy, and increases health care costs, the findings of the DAPA-CKD trial are particularly significant as they show a renal benefit of dapagliflozin treatment across CKD stages that is independent of underlying diabetes. Therefore, SGLT2 inhibitors may offer a new and unique treatment option for millions of patients with CKD worldwide for whom ACE inhibitors and ARBs were otherwise the only treatments to prevent kidney failure. Moreover, with a number-needed-to-treat of 19 to prevent 1 composite renal vascular event over a period of 2.4 years, dapagliflozin requires a much lower number needed to treat compared to ACE inhibitors and ARBs in similar patients.

The trial has several limitations in study design. For example, the management of diabetes and hypertension were left to the discretion of each trial site, in keeping with local clinical practice and guidelines. It is unknown whether this variability in the management of comorbidities that impact kidney function had an effect on the study’s results. In addition, the trial was stopped early as a result of recommendations from an independent committee due to the demonstrated efficacy of dapagliflozin. This may have reduced the statistical power to assess some of the secondary outcomes. Finally, the authors discussed an initial dip in the estimated GFR after initiation of dapagliflozin treatment, similar to that observed in other SGLT2 inhibitor clinical trials. However, they were unable to ascertain the reversibility of this effect after the discontinuation of dapagliflozin because assessment of GFR was not completed after trial closure. Nonetheless, the authors specified that the reversibility of this initial estimated GFR dip had been assessed and observed in other clinical trials involving dapagliflozin.

The nonglycemic benefits of SGLT2 inhibitors, including improvement in renal outcomes, have strong implications for the future management of patients with CKD. If this indication is approved by the FDA and recommended by clinical guidelines, the ease of SGLT2 inhibitor prescription (eg, minimal drug-drug interaction, no titration), treatment administration (orally once daily), and safety profile may lead to wide use of SGLT2 inhibitors by generalists, nephrologists, and endocrinologists in preserving or improving renal outcomes in patients at risk for end-stage kidney disease. Given that SGLT2 inhibitors are a new class of pharmacologic therapeutics, patient education should include a discussion of the possible side effects, such as euglycemic ketoacidosis, genital and urinary tract infection, and foot and leg amputation. Finally, as Strandberg and colleagues reported in a recent commentary,⁹ the safety of SGLT2 inhibitors in older adults with multimorbidity, frailty, and polypharmacy remains unclear. Thus, future studies of SGLT2 inhibitors are needed to better evaluate their clinical effects in older adults.

Applications for Clinical Practice

This trial enrolled a dedicated patient population with CKD and demonstrated a benefit of dapagliflozin in reducing renal and cardiovascular outcomes, regardless of baseline diabetes status. These drugs (dapagliflozin as well as other SGLT2 inhibitors) will likely have a prominent role in future CKD management guidelines. Until then, several barriers remain before SGLT2 inhibitors can be widely used in clinical practice. Among these barriers are FDA approval for their use in patients with and without diabetes with an estimated GFR < 30 mL/min/1.73 m² and lowering the costs of this class of drugs.

Study Overview

Objective. To assess whether dapagliflozin added to guideline-recommended therapies is effective and safe over the long-term to reduce the rate of renal and cardiovascular events in patients across multiple chronic kidney disease (CKD) stages, with and without type 2 diabetes.

Design. The Dapagliflozin and Prevention of Adverse Outcomes in CKD (DAPA-CKD) trial (NCT03036150) was a randomized, double-blind, parallel-group, placebo-controlled, multicenter event-driven, clinical trial sponsored by Astra-Zeneca. It was conducted at 386 sites in 21 countries from February 2, 2017, to June 12, 2020. A recruitment period of 24 months and a total study duration of 45 months were initially planned. The primary efficacy analysis was based on the intention-to-treat population. This was the first randomized controlled trial designed to assess the effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors on renal and cardiovascular outcomes in patients with CKD.

Setting and participants. This trial randomly assigned 4304 adult participants with CKD stages 2 to 4 (an estimated glomerular filtration rate [GFR] of 25 to 75 mL/min/1.73 m² of body-surface area) and elevated urinary albumin excretion (urinary albumin-to-creatinine ratio of 200 to 5000, measured in mg of albumin per g of creatinine) to receive dapagliflozin (10 mg once daily) or placebo. Exclusion criteria included type 1 diabetes, polycystic kidney disease, lupus nephritis, antineutrophil cytoplasmic antibody–associated vasculitis, recent immunosuppressive therapy for primary or secondary kidney disease, New York Heart Association class IV congestive heart failure, myocardial infarction, unstable angina, stroke or transient ischemic attacks, or recent coronary revascularization or valvular repair/replacement. All participants received a stable dose of renin–angiotensin system inhibitor for 4 weeks prior to screening, and the vast majority received a maximum tolerated dose at enrollment. Randomization was monitored to ensure that at least 30% of participants recruited did not have diabetes and that no more than 10% had stage 2 CKD. Participants were randomly assigned to receive dapagliflozin (n = 2152) or matching placebo (n = 2152) to ensure a 1:1 ratio of the 2 regimens. Dapagliflozin and placebo had identical appearance and administration schedules. All participants and trial personnel (except members of the independent data monitoring committee) were unaware of the trial-group assignments. After randomization, in-person study visits were conducted at 2 weeks, at 2, 4, and 8 months, and at 4-month intervals thereafter.

Main outcome measures. The primary outcome was a composite of the first occurrence of either a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes. Secondary outcomes, in hierarchical order, were: (1) the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes; (2) a composite cardiovascular outcome defined as hospitalization for heart failure or death from cardiovascular causes; and (3) death from any cause. All outcomes were assessed by time-to-event analyses.

Given the extensive prior experience with dapagliflozin, only selected adverse events were recorded. These included serious adverse events, adverse events resulting in the discontinuation of dapagliflozin or placebo, and adverse events of interest to dapagliflozin (eg, volume depletion symptoms, renal events, major hypoglycemia, fractures, diabetic ketoacidosis, events leading to higher risk of lower limb amputation, and lower limb amputations).

The incidence of each secondary outcome was similarly lower in the dapagliflozin-treated group than in the placebo group. The HR for the composite kidney outcome of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal causes was 0.56 (95% CI, 0.45-0.68; P < 0.001), and the HR for the composite cardiovascular outcome of hospitalization for heart failure or death from cardiovascular causes was 0.71 (95% CI, 0.55-0.92; P = 0.009). Death occurred in 101 participants (4.7%) in the dapagliflozin group and 146 participants (6.8%) in the placebo group (HR, 0.69; 95% CI, 0.53-0.88; P = 0.004). The known safety profile of dapagliflozin was confirmed by the similar overall incidences of adverse events and serious adverse events in the dapagliflozin and placebo groups.

Conclusion. In patients with CKD, with or without type 2 diabetes, the risk of a composite of a sustained decline in the estimated GFR of at least 50%, end-stage kidney disease, or death from renal or cardiovascular causes was significantly lowered by dapagliflozin treatment.

However, they were unable to ascertain the reversibility of this effect after the discontinuation of dapagliflozin because assessment of GFR was not completed after trial closure. Nonetheless, the authors specified that the reversibility of this initial estimated GFR dip had been assessed and observed in other clinical trials involving dapagliflozin.

The nonglycemic benefits of SGLT2 inhibitors, including improvement in renal outcomes, have strong implications for the future management of patients with CKD. If this indication is approved by the FDA and recommended by clinical guidelines, the ease of SGLT2 inhibitor prescription (eg, minimal drug-drug interaction, no titration), treatment administration (orally once daily), and safety profile may lead to wide use of SGLT2 inhibitors by generalists, nephrologists, and endocrinologists in preserving or improving renal outcomes in patients at risk for end-stage kidney disease. Given that SGLT2 inhibitors are a new class of pharmacologic therapeutics, patient education should include a discussion of the possible side effects, such as euglycemic ketoacidosis, genital and urinary tract infection, and foot and leg amputation. Finally, as Strandberg and colleagues reported in a recent commentary,⁹ the safety of SGLT2 inhibitors in older adults with multimorbidity, frailty, and polypharmacy remains unclear. Thus, future studies of SGLT2 inhibitors are needed to better evaluate their clinical effects in older adults.

Applications for Clinical Practice

This trial enrolled a dedicated patient population with CKD and demonstrated a benefit of dapagliflozin in reducing renal and cardiovascular outcomes, regardless of baseline diabetes status. These drugs (dapagliflozin as well as other SGLT2 inhibitors) will likely have a prominent role in future CKD management guidelines. Until then, several barriers remain before SGLT2 inhibitors can be widely used in clinical practice. Among these barriers are FDA approval for their use in patients with and without diabetes with an estimated GFR < 30 mL/min/1.73 m² and lowering the costs of this class of drugs.

Medtronic’s launch of a new version of its smart insulin pen with integrated continuous glucose monitoring (CGM) is the first such device for use by people with diabetes who use multiple daily injections (MDI) of insulin.

Initially launched by Companion Medical in 2017, the InPen system is a reusable insulin injector pen combined with a smartphone app that provides insulin dose calculation information and tracking.

Medtronic acquired Companion in September 2020 and now the new version, the InPen with Real-Time Guardian Connect CGM Data, allows users to view glucose readings and insulin dose information in the same app.

The InPen, a so-called “connected delivery device,” also provides reports that aggregate insulin, glucose, and carbohydrate information into graphical displays. As with other current CGM systems, the information can be sent wirelessly to a clinician. And as with insulin pumps, the pens are programmed with target blood glucose levels, insulin-to-carb ratios, and insulin sensitivity parameters. The device tracks “insulin on board” and delivers reminders for basal and bolus doses.

InPen delivers only short-acting insulin from cartridges, all the three major brands. Patients who need long-acting insulin still need to inject that separately.

Barry H. Ginsberg, MD, PhD, of Diabetes Technology Consultants, Arlington, Va., said in an interview, “People using pumps have had data integration for a while now. This is an excellent first step in data integration for people doing MDI and I am sure it will improve blood glucose control.”

Asked about comparative costs, Medtronic spokeswoman Pamela Reese said in an interview, “While insurance costs will vary, the smart pen is less expensive than the insulin pump.”

Smart pens: How large is the market?

Speaking on Nov. 14 at the Diabetes Technology Society conference, diabetes care and education specialist Hope Warshaw, RD, gave an overview of the current smart pen/connected delivery device landscape.

She noted that the patient population who might benefit from smart pens, those using MDI, which is defined as injecting both long-acting insulin and short-acting insulin before meals, may be larger than appreciated. There are about 1.6 million U.S. patients with type 1 diabetes, of whom just 30%-40% currently use insulin pumps. In addition, of the 5.8 million with type 2 diabetes who take insulin, about 29%, or 1.7 million, use MDI.

Among those with type 1 diabetes, she said that smart pens might be a good option for “people who don’t want to wear the physical pump. They can deal with the sensor, but for psychological reasons or they have dermatologic issues, they just can’t wear a pump.”

But, Ms. Warshaw stressed, the type 2 diabetes population shouldn’t be overlooked. “More and more people with type 2 diabetes are on MDI. ... In fact, there are more who use MDI than the entire population with type 1 diabetes. ... This is happening because people with type 2 are getting it earlier and living longer.”

Dr. Ginsberg views smart pens as a bridge between simple pen injectors to automated insulin delivery (AID) systems, those that link insulin pumps with CGMs.

Regarding patients with type 1 diabetes, he said, “I see pen users on MDI slowly moving to integrated systems and then, when comfortable with the technology, moving to AID, finances allowing.”

As for those with type 2 diabetes, he said that they “are less computer literate and less likely to move to integrated systems, but they will, over time.”

In all, Dr. Ginsberg said, “I see integrated pens as increasing, not decreasing, the AID market.”
 

Emerging field: “I think they’re here to stay”

The new Medtronic InPen system can still display information from other compatible CGM systems, but on a 3-hour delay. This is important since the Guardian is not currently approved for determining insulin doses. In order to do that, users must still either use readings from another CGM system on a separate app or perform fingerstick blood glucose measurements.

The InPen is the first CGM-integrated pen device but is not likely to be the last. Similar technologies are being pursued by all three of the major insulin manufacturers and some other companies.

Eli Lilly’s Humalog Tempo Pen, a modified version of KwikPen, is integrated with the Dexcom CGM. The pen itself has been cleared by the U.S. Food and Drug Administration, but some of the component parts await authorization.

Novo Nordisk is expected to file with the FDA in 2021 for its NovoPen Echo Plus.

For its part, in December 2019, Sanofi teamed up with Bioport to fit its SoloStar insulin pens with their technology called Mallya, which had received CE Mark in June 2019. That device, which clips onto the top and the button of most major pens, adds smart pen capacity via Bluetooth. BioCorp also has teamed up with other manufacturers including Roche and AgaMatrix.

Another major player, Bigfoot Biomedical, has filed with the FDA for its connected pen that works with the Abbott FreeStyle Libre 2 CGM.

Ms. Warshaw advised, “We need to start talking more about the ways that peoples’ wants, needs, and desires change and evolve over the person’s life as their diabetes evolves and as all this technology evolves.

“Time will tell how many people will be on the very expensive [AID] systems. ... Pens are cheaper. The main cost is insulin. I think they’re here to stay. The big insulin makers wouldn’t be doing it otherwise.”

Dr. Ginsberg has no disclosures. Ms. Warshaw is a consultant and writer for Companion Medical/Medtronic and a faculty member of LifeScan Diabetes Institute.

Sotagliflozin, a novel type of sodium-glucose cotransporter inhibitor, showed the diverse benefits this drug class provides along some new twists in a pair of international pivotal trials that together enrolled nearly 12,000 patients with type 2 diabetes.

Unprecedented benefits were seen for the first time with a drug, sotagliflozin (Zynquista) that produces both sodium-glucose cotransporter 2 inhibition as well as SGLT1 inhibition.

They included a big reduction in both MIs and strokes; an ability to meaningfully reduce hyperglycemia in patients with severe renal dysfunction with an estimated glomerular filtration rate (eGFR) of 25-29 mL/min per 1.73 m²; an ability to safely and effectively start in patients still hospitalized (but stable) for an acute heart failure episode; and a striking 37% relative risk reduction in cardiovascular death, heart failure hospitalizations, or an urgent outpatient visit for heart failure in 739 of the patients enrolled in both trials who had heart failure with preserved ejection fraction (HFpEF).

These studies produced for the first time evidence from controlled, prospective, randomized trials that a drug could improve the outcome of HFpEF patients.

All these novel outcomes came on top of the usual benefits clinicians have generally seen across the SGLT2 inhibitors already on the U.S. market: reductions in cardiovascular death and heart failure hospitalizations among all patients with type 2 diabetes, preservation of renal function, and hemoglobin A1c lowering among T2D patients with eGFR levels of at least 30 mL/min per 1.73 m².

“The data look spectacular,” summed up Deepak L. Bhatt, MD, who presented the results from the two trials, SOLOIST-WHF and SCORED, in talks at the virtual scientific sessions of the American Heart Association.

“I think sotagliflozin has the potential to be the best in class” based on the several added attributes shown in the two trials, he said in an interview. “We’ve shown that it is very safe, well tolerated, and effective.”

The primary results were a significant 33% relative risk reduction with sotagliflozin treatment, compared with placebo in the rate of total cardiovascular deaths, hospitalizations for heart failure, or urgent outpatient visits for heart failure during just over 9 months of median follow-up among patients with T2D recently hospitalized for heart failure in SOLOIST-WFH. And a significant 26% relative risk reduction with sotagliflozin for the same endpoint after a median follow-up of just over 14 months in SCORED, which enrolled patients with T2D and chronic kidney disease.

“Sotagliflozin adds to the SGLT2 inhibitor story,” and the SOLOIST-WHF results “may shift our focus to vulnerable, acute heart failure patients with an opportunity to treat during the transition phase,” when these patients leave the hospital, commented Jane E. Wilcox, MD, the study’s designated discussant and a heart failure cardiologist at Northwestern Medicine in Chicago.
 

A dual SGLT inhibitor

What sets sotagliflozin apart from the SGLT2 inhibitors is that it not only inhibits that protein but also SGTL1, which primarily resides in the gastrointestinal tract and is the main route for gut absorption of glucose. Dr. Bhatt said that he was unaware of any other SGLT1/2 inhibitors currently in advanced clinical testing.

The activity of sotagliflozin against the SGLT1 protein likely explains its ability to cut A1c levels in patients with severe renal dysfunction, a condition that stymies glucose lowering by SGLT2 inhibitors. In SCORED, which randomized 10,584 patients with T2D at 750 study sites in 44 countries, 813 patients (8%) had an eGFR of 25-29 mL/min per 1.73 m² at enrollment. Sotagliflozin treatment led to an average 0.6% cut in A1c in this subgroup, and by the same average amount among the patients with GFRs of 30-60 mL/min per 1.73 m2.

“This is a huge finding for endocrinologists and primary care physicians” who treat patients with T2D who have severe renal dysfunction, said Dr. Bhatt, a professor of medicine at Harvard Medical School in Boston. “It’s a good enough reason by itself to approve this drug.”

The same mechanism may also be behind another unexpected finding in SCORED. Treatment with sotagliflozin cut the rate of total episodes of cardiovascular death, nonfatal MI, or nonfatal stroke by an absolute 1.6%, compared with placebo, and by a relative 23%. This benefit was largely driven by a 32% relative risk reduction total in MIs, and a 34% relative risk reduction in total stroke, both significant differences.

“No SGLT2 inhibitor has shown a reduction in stroke, and the MI signals have been mixed. The sizable MI and stroke effects are unique to sotagliflozin,” compared with the SGLT2 inhibitors, and likely reflect one or more mechanisms that result from blocked gut SGLT1 and a cut in GI glucose uptake, said Dr. Bhatt. “Probably some novel mechanism we don’t fully understand.”
 

First-ever HFpEF benefit

In contrast to these two benefits that are probably unique to drugs that inhibit the SGLT1 protein, sotagliflozin showed two other notable and unprecedented benefits that are likely generalizable to the SGLT2 inhibitors.

First is the striking benefit for HFpEF. Neither SOLOIST, which enrolled 1,222 patients with T2D and just hospitalized for worsening heart failure, nor SCORED, which enrolled patients with T2D and chronic kidney disease based exclusively on an eGFR of 25-60 mL/min per 1.73 m², excluded patients with HFpEF, defined as heart failure patients with a left ventricular ejection fraction of at least 50%. The two studies together included a total of 739 of these patients, and they split fairly evenly between treatment with sotagliflozin or placebo.

The combined analysis showed that the incidence rate for the primary endpoint in both SOLOIST and SCORED was 59% with placebo and 39% with sotagliflozin, an absolute event reduction of 11.6 events/100 patient-years, and a significant 37% relative risk reduction, with a number needed to treat to prevent 1 event per year event of 9.

Although this observation comes from a nonprespecified combined analysis, “to me this result seems real, and I think it’s a class effect that I’m willing to extrapolate to the SGLT2 inhibitors,” Dr. Bhatt said. “It will change my practice,” he added, by spurring him to more aggressively prescribe an SGLT2 inhibitor to a patient with T2D and HFpEF.

“I think there has been some hesitation to use SGLT2 inhibitors in T2D patients with HFpEF” because of the paucity of data in this population, even though labeling and society recommendations do not rule it out. “I hope this finding will move that needle, and also generally improve SGLT2 inhibitor uptake, which has been low,” he said.
 

Also safe soon after acute heart failure decompensation

The other finding likely generalizable to SGLT2 inhibitors stems from the design of SOLOIST-WHF, which tested the efficacy and safety of starting sotagliflozin in patients with T2D as soon as they were stable after hospitalization for acute heart failure decompensation.

“Showing safety and efficacy when started in the hospital is pretty meaningful, because its tells patients that this drug is important and they should stay on it,” which should improve adherence, predicted Dr. Bhatt, who is also executive director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital in Boston. “That’s the ultimate treatment path to prevent patients from falling through the cracks” and failing to receive an SGLT2 inhibitor.

SOLOIST-WHF enrolled patients hospitalized for worsening heart failure who also required intravenous diuretic treatment but had become stable enough to transition to an oral diuretic and come off oxygen. During a median follow-up of just over 9 months (both SOLOIST-WHF and SCORED ended sooner than planned because of a change in drug company sponsorship), treatment with sotagliflozin cut the primary endpoint by a relative 33%, compared with placebo, and with an absolute reduction of 25 events per 100 patient-years for a number needed to treat of 4. Sotagliflozin produced a strikingly high level of treatment efficiency driven by the high event rate in these recently decompensated patients. The benefit also appeared quickly, with a significant cut in events discernible within 28 days.

Extrapolating this finding to the SGLT2 inhibitors is “not a huge leap of faith,” Dr. Bhatt said.

“There is a role for sotagliflozin in acute heart failure. It showed benefit in these high-risk, transition-phase patients,” said Dr. Wilcox.

Simultaneously with Dr. Bhatt’s presentation, results of SOLOIST-WHF and SCORED were published online in the New England Journal of Medicine.

The trials were sponsored initially by Sanofi, and more recently by Lexicon. Dr. Bhatt has received research funding from both companies, and also from several other companies. He also is an adviser to several companies. Dr. Wilcox has been a consultant to Boehringer Ingelheim and Medtronic.

The other finding likely generalizable to SGLT2 inhibitors stems from the design of SOLOIST-WHF, which tested the efficacy and safety of starting sotagliflozin in patients with T2D as soon as they were stable after hospitalization for acute heart failure decompensation.

“Showing safety and efficacy when started in the hospital is pretty meaningful, because its tells patients that this drug is important and they should stay on it,” which should improve adherence, predicted Dr. Bhatt, who is also executive director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital in Boston. “That’s the ultimate treatment path to prevent patients from falling through the cracks” and failing to receive an SGLT2 inhibitor.

SOLOIST-WHF enrolled patients hospitalized for worsening heart failure who also required intravenous diuretic treatment but had become stable enough to transition to an oral diuretic and come off oxygen. During a median follow-up of just over 9 months (both SOLOIST-WHF and SCORED ended sooner than planned because of a change in drug company sponsorship), treatment with sotagliflozin cut the primary endpoint by a relative 33%, compared with placebo, and with an absolute reduction of 25 events per 100 patient-years for a number needed to treat of 4. Sotagliflozin produced a strikingly high level of treatment efficiency driven by the high event rate in these recently decompensated patients. The benefit also appeared quickly, with a significant cut in events discernible within 28 days.

Extrapolating this finding to the SGLT2 inhibitors is “not a huge leap of faith,” Dr. Bhatt said.

“There is a role for sotagliflozin in acute heart failure. It showed benefit in these high-risk, transition-phase patients,” said Dr. Wilcox.

Simultaneously with Dr. Bhatt’s presentation, results of SOLOIST-WHF and SCORED were published online in the New England Journal of Medicine.

The trials were sponsored initially by Sanofi, and more recently by Lexicon. Dr. Bhatt has received research funding from both companies, and also from several other companies. He also is an adviser to several companies. Dr. Wilcox has been a consultant to Boehringer Ingelheim and Medtronic.

Sotagliflozin, a novel type of sodium-glucose cotransporter inhibitor, showed the diverse benefits this drug class provides along some new twists in a pair of international pivotal trials that together enrolled nearly 12,000 patients with type 2 diabetes.

Unprecedented benefits were seen for the first time with a drug, sotagliflozin (Zynquista) that produces both sodium-glucose cotransporter 2 inhibition as well as SGLT1 inhibition.

They included a big reduction in both MIs and strokes; an ability to meaningfully reduce hyperglycemia in patients with severe renal dysfunction with an estimated glomerular filtration rate (eGFR) of 25-29 mL/min per 1.73 m²; an ability to safely and effectively start in patients still hospitalized (but stable) for an acute heart failure episode; and a striking 37% relative risk reduction in cardiovascular death, heart failure hospitalizations, or an urgent outpatient visit for heart failure in 739 of the patients enrolled in both trials who had heart failure with preserved ejection fraction (HFpEF).

These studies produced for the first time evidence from controlled, prospective, randomized trials that a drug could improve the outcome of HFpEF patients.

All these novel outcomes came on top of the usual benefits clinicians have generally seen across the SGLT2 inhibitors already on the U.S. market: reductions in cardiovascular death and heart failure hospitalizations among all patients with type 2 diabetes, preservation of renal function, and hemoglobin A1c lowering among T2D patients with eGFR levels of at least 30 mL/min per 1.73 m².

“The data look spectacular,” summed up Deepak L. Bhatt, MD, who presented the results from the two trials, SOLOIST-WHF and SCORED, in talks at the virtual scientific sessions of the American Heart Association.

“I think sotagliflozin has the potential to be the best in class” based on the several added attributes shown in the two trials, he said in an interview. “We’ve shown that it is very safe, well tolerated, and effective.”

The primary results were a significant 33% relative risk reduction with sotagliflozin treatment, compared with placebo in the rate of total cardiovascular deaths, hospitalizations for heart failure, or urgent outpatient visits for heart failure during just over 9 months of median follow-up among patients with T2D recently hospitalized for heart failure in SOLOIST-WFH. And a significant 26% relative risk reduction with sotagliflozin for the same endpoint after a median follow-up of just over 14 months in SCORED, which enrolled patients with T2D and chronic kidney disease.

“Sotagliflozin adds to the SGLT2 inhibitor story,” and the SOLOIST-WHF results “may shift our focus to vulnerable, acute heart failure patients with an opportunity to treat during the transition phase,” when these patients leave the hospital, commented Jane E. Wilcox, MD, the study’s designated discussant and a heart failure cardiologist at Northwestern Medicine in Chicago.
 

A dual SGLT inhibitor

What sets sotagliflozin apart from the SGLT2 inhibitors is that it not only inhibits that protein but also SGTL1, which primarily resides in the gastrointestinal tract and is the main route for gut absorption of glucose. Dr. Bhatt said that he was unaware of any other SGLT1/2 inhibitors currently in advanced clinical testing.

The activity of sotagliflozin against the SGLT1 protein likely explains its ability to cut A1c levels in patients with severe renal dysfunction, a condition that stymies glucose lowering by SGLT2 inhibitors. In SCORED, which randomized 10,584 patients with T2D at 750 study sites in 44 countries, 813 patients (8%) had an eGFR of 25-29 mL/min per 1.73 m² at enrollment. Sotagliflozin treatment led to an average 0.6% cut in A1c in this subgroup, and by the same average amount among the patients with GFRs of 30-60 mL/min per 1.73 m2.

“This is a huge finding for endocrinologists and primary care physicians” who treat patients with T2D who have severe renal dysfunction, said Dr. Bhatt, a professor of medicine at Harvard Medical School in Boston. “It’s a good enough reason by itself to approve this drug.”

The same mechanism may also be behind another unexpected finding in SCORED. Treatment with sotagliflozin cut the rate of total episodes of cardiovascular death, nonfatal MI, or nonfatal stroke by an absolute 1.6%, compared with placebo, and by a relative 23%. This benefit was largely driven by a 32% relative risk reduction total in MIs, and a 34% relative risk reduction in total stroke, both significant differences.

“No SGLT2 inhibitor has shown a reduction in stroke, and the MI signals have been mixed. The sizable MI and stroke effects are unique to sotagliflozin,” compared with the SGLT2 inhibitors, and likely reflect one or more mechanisms that result from blocked gut SGLT1 and a cut in GI glucose uptake, said Dr. Bhatt. “Probably some novel mechanism we don’t fully understand.”
 

First-ever HFpEF benefit

In contrast to these two benefits that are probably unique to drugs that inhibit the SGLT1 protein, sotagliflozin showed two other notable and unprecedented benefits that are likely generalizable to the SGLT2 inhibitors.

First is the striking benefit for HFpEF. Neither SOLOIST, which enrolled 1,222 patients with T2D and just hospitalized for worsening heart failure, nor SCORED, which enrolled patients with T2D and chronic kidney disease based exclusively on an eGFR of 25-60 mL/min per 1.73 m², excluded patients with HFpEF, defined as heart failure patients with a left ventricular ejection fraction of at least 50%. The two studies together included a total of 739 of these patients, and they split fairly evenly between treatment with sotagliflozin or placebo.

The combined analysis showed that the incidence rate for the primary endpoint in both SOLOIST and SCORED was 59% with placebo and 39% with sotagliflozin, an absolute event reduction of 11.6 events/100 patient-years, and a significant 37% relative risk reduction, with a number needed to treat to prevent 1 event per year event of 9.

Although this observation comes from a nonprespecified combined analysis, “to me this result seems real, and I think it’s a class effect that I’m willing to extrapolate to the SGLT2 inhibitors,” Dr. Bhatt said. “It will change my practice,” he added, by spurring him to more aggressively prescribe an SGLT2 inhibitor to a patient with T2D and HFpEF.

“I think there has been some hesitation to use SGLT2 inhibitors in T2D patients with HFpEF” because of the paucity of data in this population, even though labeling and society recommendations do not rule it out. “I hope this finding will move that needle, and also generally improve SGLT2 inhibitor uptake, which has been low,” he said.

A panel convened by The Lancet has published a comprehensive report calling for major initiatives to improve diabetes prevention and care around the world.

The article was published online Nov. 12, just ahead of World Diabetes Day.

Of the 463 million people with diabetes worldwide in 2019, 80% live in low- and middle-income countries. The condition reduces life expectancy in middle-aged adults by 4-10 years, including increasing the risk of death from cardiovascular disease, kidney disease, and cancer by up to threefold. It is also a leading cause of nontraumatic amputation and blindness.

Use of evidence-based interventions, if implemented and managed properly, could prevent thousands of deaths globally every day, stressed the commission.

“There is an enormous amount of knowledge that we have amassed over the years. We need good preventive care and we need to ensure that diabetes patients, once diagnosed, have good continuous care. There is an urgent need for decision-makers, policymakers, and payers to make things happen,” the leader of the multidisciplinary commission, Juliana C.N. Chan, MBChB, MD, said in an interview.

And now diabetes has emerged as a major risk factor for death from COVID-19, particularly in the setting of inadequate glycemic control.

“COVID-19 has exposed the vulnerability of individuals with diabetes,” said Dr. Chan, of the Hong Kong Institute of Diabetes and Obesity. “We should use the pandemic as an opportunity to implement solutions.”
 

Physician education key, trickling down to field workers and patients

First on the agenda, she says, should be “physician education. There are many primary care providers and internal medicine physicians whose knowledge needs to be updated.”

“Then doctors need to transfer this information to other people, such as nurses and community field workers. We cannot just rely on doctors; we need to train nonmedics” so that knowledge about how to prevent, treat, and manage diabetes long term is communicated right down the health care chain, she explained.

“They need to know how to look at people’s eyes and feet, how to do blood and urine tests, and how to collect data. Then they need to educate patients on what they should be doing, on how to practice self-care,” she added.

“We need to change our way of thinking, redesign clinic flow and how you build a team. And those care teams need to know how to collect data, and then use that data to monitor patients and to stratify individual risk, to ensure that what has been said has been done, as well as to inform practice and policies” through, for example, the establishment of diabetes registers.

The focus needs to be on “lifelong integrated care, the right treatment at the right time,” she emphasized. History-taking, clinical and laboratory assessments, as well as monitoring of macrovascular and microvascular complications, comorbidities, and medications, are all key.

Just a few simple things, if properly implemented, could make a big difference, Dr. Chan stressed.

For example, implementing a structured lifestyle intervention and use of metformin can each prevent or delay type 2 diabetes in individuals with impaired glucose tolerance by 30%-50%, and sustained weight reduction in patients with obesity by 15 kg (33 lb) or more can induce remission of type 2 diabetes for up to 2 years.

And there are plenty of medications that are “very affordable even in low- and middle-income countries” to treat diabetes and associated risk factors, including metformin, “statins, and RAS inhibitors,” she noted.

For instance, the 10 low- and middle-income countries with the greatest burden of diabetes (China, India, Brazil, Mexico, Indonesia, Egypt, Pakistan, Bangladesh, Turkey, Thailand) account for 217 million cases of type 2 diabetes, representing nearly 50% of all diabetes cases.

The commission estimated that 3.2 million of these individuals would die in 3 years if not treated, with 1.3 million of these deaths due to cardiovascular disease.

By reducing hemoglobin A1c, blood pressure, and LDL-cholesterol through achieving a diagnosis rate of 50%, ensuring access to essential medicines in at least 70% of patients, and with a support system to sustain reductions in these risk factors over 3 years, up to 800,000 premature deaths could be avoided.
 

People with type 1 diabetes dying; WHO launches initiative

In an accompanying commentary (2020 Nov 12. doi: 10.1016/S0140-6736[20]32378-3), Katie Dain, chief executive officer of the Noncommunicable Diseases (NCD) Alliance, points out that only half of people living with diabetes around the world – and just one in seven in Africa – have reliable access to insulin.

“Lots of people with type 1 diabetes are still dying due to lack of insulin,” Dr. Chan said in an interview. “We need to elevate basic care to intermediate and ensure that basal-bolus insulin and glucose-monitoring tools are available and that patients are trained in self-care. In that way, 80% of type 1 diabetes deaths could be prevented.”

Ms. 3Dain agrees, stressing, “Political rhetoric and commitments have yet to translate into sufficient and sustainable action for people living with diabetes worldwide, and particularly for those in [low- and middle-income countries].”

The Lancet Commission document also emphasizes the importance of support for pregnant women with diabetes and attention to the psychosocial needs of people with diabetes.

And it stresses society-, population-, and community-based strategies for type 2 diabetes prevention including health awareness programs, food policies, and broad use of nonphysician personnel to deliver diabetes prevention efforts.

In tandem with World Diabetes Day, the World Health Organization will announce the development of the WHO Global Diabetes Compact, which will be launched in April 2021.

This will aim to implement the commission’s recommendations through partnerships with governments, care providers, patient advocates, and nongovernmental organizations.

Together, they will “support countries to mobilize resources and accelerate structural transformations, which will enable the scale-up of access to essential diabetes medicines and technologies, inclusion of diagnosis and treatment of diabetes in primary health care and universal health coverage packages, and reduction of major population-level diabetes risk factors such as obesity,” according to another Lancet editorial accompanying the report.

“The evidence-base for improving diabetes prevention and care is strong. The question now for diabetes advocates is how to achieve the comprehensive, systems-level change needed to translate this evidence into action.”

Dr. Chan has reported receiving grants from AstraZeneca, Lilly, Lee Powder, Hua Medicine, and Qualigenics, as well as grants and personal fees from Bayer, Boehringer Ingelheim, Sanofi, Novartis, Merck, and MSD outside the submitted work. She has reported being the chief executive officer (pro bono) of the Asia Diabetes Foundation and a cofounder of GemVCare. She also holds a patent for genetic markers for diabetes and its complications. Ms. Dain has reported no relevant financial relationships.

A new guideline from the Kidney Disease: Improving Global Outcomes group addressing issues around diabetes management in patients with chronic kidney disease (CKD) has just been published in synopsis form in Annals of Internal Medicine.

The full guideline, including 12 recommendations and 48 practice points for clinicians caring for patients with diabetes and CKD, was published last month in Kidney International and on the KDIGO website.

More than 40% of people with diabetes develop CKD, and a significant number develop kidney failure requiring dialysis or transplant. This is the first guidance from KDIGO to address the comorbidity.

The new synopsis is aimed at primary care and nonnephrology specialist clinicians who manage patients with diabetes and CKD, in addition to nephrologists, first author Sankar D. Navaneethan, MD, said in an interview.

“Most of these patients are in the hands of primary care, endocrinology, and cardiology. We want to emphasize when they see patients with different severities of kidney disease [is] what are some of the things they have to be cognizant of,” said Dr. Navaneethan, professor of medicine and director of clinical research in the section of nephrology at Baylor College of Medicine, Houston.

The synopsis summarizes key recommendations from the larger guidance regarding comprehensive care needs, glycemic monitoring and targets, lifestyle interventions, glucose-lowering therapies, and educational/integrated care approaches.

It does not depart from prior diabetes guidelines, but it does provide advice for specific situations relevant to CKD, such as the limitations of hemoglobin A1c when estimated glomerular filtration rate (eGFR) drops below 30 mL/min per 1.73m², and dietary protein consumption. It is based on published evidence up until February 2020.

For the nephrologist audience in particular, Dr. Navaneethan said, “we wanted to highlight team-based care, interacting with other specialists and working with them.”

“We [nephrologists] are more used to team-based care in dialysis patients. ... So we wanted to highlight that self-management programs and team-based care are important for empowering patients.”

“As nephrologists, we might not be comfortable starting patients on an SGLT2 [sodium-glucose cotransporter 2] inhibitor. We may need to reach out to our endocrinology or primary care colleagues and learn from them,” he explained.
 

RAS inhibitor use, smoking cessation, glycemic targets

Under “comprehensive care,” the guideline panel recommends treatment with an ACE inhibitor or an angiotensin II receptor blocker – renin-angiotensin system (RAS) blockade – for patients with diabetes, hypertension, and albuminuria (albumin-creatinine ratio >30 mg/g).

These medications should be titrated to the highest approved tolerated dose, with close monitoring of serum potassium and serum creatinine levels within 2-4 weeks of initiation or change in dose.

The document guides clinicians on that monitoring, as well as on RAS blockade use in patient subgroups, use of alternative agents, and mitigation of adverse effects.

Patients with diabetes and CKD who use tobacco should be advised to quit.

The group recommended A1c to monitor glycemic control in patients with diabetes and CKD not receiving dialysis.

However, when eGFR is below 30 mL/min per 1.73m2, A1c levels tend to be lower because of shortened erythrocyte lifespan, which interpretation should take into account. Continuous glucose monitoring can be used as an alternative because it is not affected by CKD.

Glycemic targets should be individualized depending on hypoglycemia risk, ranging from 6.5% to 8.0% for A1c or time in range of 70-180 mg/dL for continuous glucose monitoring readings.
 

SGLT2 inhibitors, metformin, and GLP-1 agonists

The panel also recommends treatment with both metformin and an SGLT2 inhibitor for patients with type 2 diabetes, CKD, and an eGFR ≥30 mL/min per 1.73m2.

For those who do not achieve glycemic targets or who cannot take those medications, a long-acting glucagonlike peptide–1 receptor agonist can be used instead.

Clinical trial data are summarized for the SGLT2 inhibitor canagliflozin supporting its use in patients with CKD specifically, along with mitigation of adverse events. Last year, the Food and Drug Administration approved this agent to slow the progression of diabetic nephropathy based on the CREDENCE study.

Results from the DAPA-CKD trial showing CKD reduction with another SGLT2 inhibitor, dapagliflozin, were not available at the time the new document was written, nor was the recent study showing diabetic CKD benefit for the novel mineralocorticoid receptor antagonist finerenone, Dr. Navaneethan noted.

The panel determined that there is insufficient evidence for adding other glucose-lowering agents to insulin in patients with type 1 diabetes and CKD.
 

Lifestyle interventions: Dietary protein, sodium, and physical activity

Most of the dietary guidance for patients with diabetes and CKD is the same as for the general population, including a recommendation to eat a diet high in vegetables, fruits, whole grains, fiber, legumes, plant-based proteins, unsaturated fats, and nuts, and lower in processed meats, refined carbohydrates, and sweetened beverages.

However, the guideline details two key areas that differ, one with regard to protein intake and the other on sodium.

Although lower protein intake had been advised in the past for patients with CKD, clinical trial evidence has not shown protein restriction to reduce glomerular hyperfiltration or slow kidney disease progression.

Therefore, the same level recommended for the general population – 0.8 g/kg per day – is also advised for those with diabetes and CKD who are not on dialysis.

Those who are on dialysis can increase daily protein intake to 1.0-1.2 g/kg per day to offset catabolism and negative nitrogen imbalance.

Because kidney function decline is associated with sodium retention that can raise cardiovascular risk, sodium should be limited to less than 2 g/day (or less than 90 mmol or 5 g of sodium chloride per day).

The panel also recommended moderate-intensity physical activity for at least 150 minutes per week or to tolerance.

“We wanted to emphasize how important lifestyle is. It’s the foundation you want to build on. You can take medications without all these other things – exercise, diet, weight loss – but they won’t be nearly as effective,” Dr. Navaneethan commented.
 

Self-management education, team-based care

The final section of the synopsis advises that people with diabetes and CKD receive structured self-management educational programs, and that “policy makers and institutional decision-makers implement team-based, integrated care focused on risk evaluation and patient empowerment to provide comprehensive care in patients with diabetes and CKD.”

Despite limited data for those measures specifically in patients with diabetes and CKD, “the working group believed that well-informed patients would choose self-management as the cornerstone of any chronic care model; therefore, a high value was placed on the potential benefits of self-management education programs in persons with diabetes and CKD.”

And regarding team-based care, “despite a paucity of direct evidence, the working group judged that multidisciplinary integrated care for patients with diabetes and CKD would represent a good investment.”

The guidelines will likely be updated in the next 1-2 years, Dr. Navaneethan said in an interview.

A new guideline from the Kidney Disease: Improving Global Outcomes group addressing issues around diabetes management in patients with chronic kidney disease (CKD) has just been published in synopsis form in Annals of Internal Medicine.

The full guideline, including 12 recommendations and 48 practice points for clinicians caring for patients with diabetes and CKD, was published last month in Kidney International and on the KDIGO website.

More than 40% of people with diabetes develop CKD, and a significant number develop kidney failure requiring dialysis or transplant. This is the first guidance from KDIGO to address the comorbidity.

The new synopsis is aimed at primary care and nonnephrology specialist clinicians who manage patients with diabetes and CKD, in addition to nephrologists, first author Sankar D. Navaneethan, MD, said in an interview.

“Most of these patients are in the hands of primary care, endocrinology, and cardiology. We want to emphasize when they see patients with different severities of kidney disease [is] what are some of the things they have to be cognizant of,” said Dr. Navaneethan, professor of medicine and director of clinical research in the section of nephrology at Baylor College of Medicine, Houston.

The synopsis summarizes key recommendations from the larger guidance regarding comprehensive care needs, glycemic monitoring and targets, lifestyle interventions, glucose-lowering therapies, and educational/integrated care approaches.

It does not depart from prior diabetes guidelines, but it does provide advice for specific situations relevant to CKD, such as the limitations of hemoglobin A1c when estimated glomerular filtration rate (eGFR) drops below 30 mL/min per 1.73m², and dietary protein consumption. It is based on published evidence up until February 2020.

For the nephrologist audience in particular, Dr. Navaneethan said, “we wanted to highlight team-based care, interacting with other specialists and working with them.”

“We [nephrologists] are more used to team-based care in dialysis patients. ... So we wanted to highlight that self-management programs and team-based care are important for empowering patients.”

“As nephrologists, we might not be comfortable starting patients on an SGLT2 [sodium-glucose cotransporter 2] inhibitor. We may need to reach out to our endocrinology or primary care colleagues and learn from them,” he explained.
 

RAS inhibitor use, smoking cessation, glycemic targets

Under “comprehensive care,” the guideline panel recommends treatment with an ACE inhibitor or an angiotensin II receptor blocker – renin-angiotensin system (RAS) blockade – for patients with diabetes, hypertension, and albuminuria (albumin-creatinine ratio >30 mg/g).

These medications should be titrated to the highest approved tolerated dose, with close monitoring of serum potassium and serum creatinine levels within 2-4 weeks of initiation or change in dose.

The document guides clinicians on that monitoring, as well as on RAS blockade use in patient subgroups, use of alternative agents, and mitigation of adverse effects.

Patients with diabetes and CKD who use tobacco should be advised to quit.

The group recommended A1c to monitor glycemic control in patients with diabetes and CKD not receiving dialysis.

However, when eGFR is below 30 mL/min per 1.73m2, A1c levels tend to be lower because of shortened erythrocyte lifespan, which interpretation should take into account. Continuous glucose monitoring can be used as an alternative because it is not affected by CKD.

Glycemic targets should be individualized depending on hypoglycemia risk, ranging from 6.5% to 8.0% for A1c or time in range of 70-180 mg/dL for continuous glucose monitoring readings.
