Diabetes

A protocol developed in the United Kingdom that allows commercial pilots with insulin-treated diabetes to fly airplanes has resulted in precise glycemic control during flight and no safety issues, new research finds.

The results are believed to be the largest-ever dataset for people with insulin-treated diabetes in “safety-critical” occupations, said Gillian L. Garden, MD, who presented the findings this week at the virtual annual meeting of the European Association for the Study of Diabetes.

The protocol, which involves multiple glucose measurements before and throughout flights and corrective action for out-of-range values, resulted in 98% of glucose values in target range with no pilot incapacitation. The results were also published in Diabetes Care earlier this year, noted Dr. Garden, a clinical fellow in diabetes and endocrinology at the Royal Surrey NHS Foundation Trust, Guildford, England.

“There were no safety concerns at all and certainly no episodes of pilot incapacitation throughout the [7.5] years of the study. Our study proves that the protocol is feasible, is practical to implement, and is easily understood by both pilots and copilots,” she observed.

Dr. Garden foresees wider use of this approach: “We believe the study is of international importance and this protocol could be adopted by other aviation authorities to allow more insulin-treated pilots worldwide to be able to fly commercial aircraft.”

“With proper oversight and a defined protocol such as the one that we’ve been working to produce it is possible for anybody with insulin-treated diabetes to, in fact, adequately perform other safety-critical occupations as well, and it would be good to see fewer people being discriminated against on the basis of their diabetes,” she emphasized.
 

‘Impressive’ study of highly motivated individuals

Historically, insulin-treated patients – with both types of diabetes – had been barred from many “safety-critical” occupations, including commercial airline piloting. This was out of concern both for the potential immediate effects of hypoglycemia, including cognitive impairment and slowing of reaction times, as well as the long-term effects of diabetes, including vision loss and nerve damage, Dr. Garden explained.

However, “with advances in diabetes management, including different insulin types, methods of delivery, and glucose-monitoring systems, it’s now possible for individuals to have excellent glycemic control. This, along with the implementation of legislation against discrimination, has allowed insulin-treated people to no longer be debarred from certain employments,” she explained during an EASD press briefing on Sept. 24.

An expert panel convened in 2010 by the U.K. Civil Aviation Authority developed the protocol, and in 2012, the CAA began issuing class 1 medical certificates to insulin-treated pilots. The protocol was subsequently adopted by Ireland in 2015 and by Austria in 2016.

Initial results from nearly 9,000 glucose readings of 26 U.K. pilots who received a certificate between 2012 and 2015 were reported at the EASD 2016 Annual Meeting and published in 2017.

The current study is far larger, with 38,621 glucose readings from 49 pilots from the United Kingdom, Ireland, and Austria who have been using the protocol since 2012. 

Mark Evans, MD, of Addenbrookes Hospital, Cambridge, England, said in an interview that “I thought this was a fascinating paper. ... I was deeply impressed by the data.”

Dr. Evans, who chairs the U.K. Department of Transport advisory panel on driving and diabetes, also noted: “The group of people with insulin-treated diabetes flying planes are a phenomenally motivated group who are prepared to do things that probably most drivers of motor vehicles would find oppressive or very difficult to do.”

“I thought the outcomes were really impressive in terms of the amount of time they were able to maintain themselves within glucose target ranges.”

Indeed, Dr. Garden said, “pilots are typically very organized and used to dealing with strict protocols with regard to all of the processes they have to follow before they fly and the safety checks they have to do. They adapted to this additional safety measure really well.”
 

Traffic light protocol keeps pilots in range

The protocol requires pilots to perform fingerstick glucose checks 30 minutes prior to flight, every hour during flight, and 30 minutes before landing. They must also attend clinical reviews every 6 months.

A traffic light system is used to denote acceptable pre- and in-flight glucose levels, with green meaning acceptable (5.0-15.0 mmol/L [90-270 mg/dL]), amber indicating caution for low (4.0-4.9 mmol/L [72-88 mg/dL]) or high (15.1-20.0 mmol/L [272-360 mg/dL]) blood glucose. Red requires immediate action (low blood glucose <4 mmol/L [72 mg/dL] and high >20 mmol/L [>360 mg/dL]).

Low amber values require the pilot to ingest 10-15 fast-acting carbohydrates and retest after 30 minutes. Low red values indicate the pilot must hand over the controls to the copilot. High readings of >15.0 mmol/L (>270 mg/dL) require an insulin dosing review. A high red value also requires the pilot to hand over the controls.

Of the 49 pilots, 84% had type 1 diabetes and 16% had insulin-treated type 2 diabetes. Most (61%) had class 1 medical certificates (required to validate a commercial pilot license) and 39% had class 2 medical certificates (required to validate a private pilot’s license). Median diabetes duration was 10.9 years.

Of note, all had become pilots prior to diabetes onset. As of now, the EU Aviation Safety Agency doesn’t allow people with preexisting insulin-treated diabetes to become pilots.

“We are fighting to change that, but with the U.K. leaving the EU, the Civil Aviation Authority might pursue it [separately]. We don’t know how that will pan out,” Dr. Garden noted during the briefing.

Over the 7.5 years, 97.7% of readings were within the green range, while just 1.42% were in the low amber range and 0.75% in the high amber range. Just 48 readings (0.12%) were in the low red range and 6 (0.02%) in the high red range. Of the 48 low reds, just 14 were recorded during flight. Of the six high reds, only two occurred during flight.

There were no instances of pilot incapacitation or changes in average hemoglobin A1c.

The results should alleviate concerns expressed after a prior report that pilots’ overall glycemic control could worsen if they pushed too hard to avoid lows, Dr. Garden noted.

The proportion of out-of-range values declined from 5.7% in 2013 to 1.2% in 2019. Low red values didn’t change (0.2% in 2013 and 0.1% in 2019) but high red values had completely disappeared by 2017.
 

What about CGM?

In response to a question during the briefing about use of continuous glucose monitoring, Dr. Garden said that some of the pilots were using CGM in addition to following the fingerstick protocol.

At the time the protocol was developed a decade ago, CGM wasn’t considered accurate enough and there wasn’t evidence for its use at high altitude.

But there has been a great deal more data since then, she said, noting “we believe it would be safer to use now because of how good that equipment is. ... Certainly, there’s a good number [of pilots] using CGM, and hopefully that will increase and the protocol will change to allow them all to use CGM if they want to.

“I think we’ll probably see CGM in the protocol within the next year to 2 years. Hopefully, that will make things a lot easier, so pilots won’t have to prick their fingers while they’re flying.”

Her group is currently conducting a study (DEXFLY) on use of the Dexcom G6 in addition to fingersticks in commercial pilots with insulin-treated diabetes. Results are expected by the end of the year.

Dr. Evans commented: “I think it’s a no-brainer that CGM will become the gold standard. I understand why they’re going to want to be cautious about this, but if they can generate data to show it will be a low-risk change, I think it will come.”

He also noted that it was only a couple of years ago that U.K. law was changed to allow car drivers with insulin-treated diabetes to use CGM as part of their glucose-testing requirements (before driving and every 2 hours). CGM still isn’t approved for use by drivers of trucks or other large vehicles, but “I think at some point in the future it will become more accepted,” Dr. Evans commented.

Dr. Garden reported no relevant financial relationships. Dr. Evans has reported being an advisory board member of, speaker for, and/or grant recipient from Novo Nordisk, Dexcom, Medtronic, Abbott, Eli Lilly, and Roche.

To protect the heart and kidneys, sodium-glucose transporter 2 (SGLT2) inhibitors and glucagonlike peptide–1 (GLP-1) receptor agonists should be considered for people with type 2 diabetes and chronic kidney disease (CKD), the American Heart Association advised in a new scientific statement.

Taken together, the results of relevant clinical trials indicate that SGLT2 inhibitors and GLP-1 receptor agonists safely and significantly reduce the risk for cardiovascular (CV) events, death, and the slow progression of CKD to end-stage kidney disease, including the risks for dialysis, transplantation, and death, the writing group says.

The scientific statement was published online Sept. 28 in Circulation.

“There has been rapid reporting of high-quality data in the cardio-renal-metabolic space with significant heart and kidney benefits, particularly with these two newer classes of antihyperglycemic agents,” Janani Rangaswami, MD, who chaired the writing group, said in an interview.

“More recent data show benefits in chronic kidney disease and heart failure even in patients without diabetes,” said Dr. Rangaswami, Einstein Medical Center and Sidney Kimmel Medical College, both in Philadelphia.

“These data are practice-changing in both cardiology and nephrology, and usher in a new era of disease-modifying therapies in heart and kidney disease,” Dr. Rangaswami added.
 

Recommendations at a glance

• Provide early and ongoing assessment of risks for CVD and CKD to patients who may benefit from SGLT2 inhibitors of GLP-1 receptor agonists.
• Tailor medication choices that meet the needs of individual patients. Realize that, given “consistent class-wide effects,” the choice of a specific SGLT2 inhibitor or GLP-1 receptor agonist may be dictated by affordability, coverage, and formulary considerations.
• Adjust all medications in tandem with these medicines and consider the burden of polypharmacy, which is common among people with type 2 diabetes. Adjust concomitant therapies and deprescribe where possible.
• Identify risks for hypoglycemia and educate patients on the signs so they can seek treatment quickly.
• Monitor and control high blood pressure.
• Counsel patients about the risks for and symptoms of euglycemic diabetic ketoacidosis when taking SGLT2 inhibitors, as well as classic DKA, which can be fatal.
• Regularly screen and counsel patients about foot care to prevent foot ulcers or blisters that can quickly become infected and lead to amputation.

The writing group identified two additional patient subgroups that may benefit from SGLT2 inhibitors and GLP-1 receptor agonists: those with heart failure with reduced ejection fraction with or without diabetes; and those with CKD who do not have diabetes. They say more data are anticipated to validate the use of SGLT2 inhibitors and GLP-1 receptor agonists in these “at-risk” patients.
 

Collaborative care model

The writing group proposed a collaborative care model, bridging cardiologists, nephrologists, endocrinologists, and primary care physicians, to help facilitate the “prompt and appropriate” integration of these new classes of medications in the management of patients with type 2 diabetes and CKD.

There is “an unmet need for a cardio-renal-metabolic care model that incorporates best practices in the real world to help align these therapies, especially with vulnerable high-risk patients with cardiorenal disease, and to overcome barriers toward uptake of these agents. Hopefully this statement provides some guidance to the cardiology and nephrology communities in that area,” Dr. Rangaswami said in an interview.

But old habits die hard, as research continues to show the slow adoption of these newer medications in the real world.

For example, a large observational study published last year showed a “striking” discordance between evidence-based, guideline-recommended use of SGLT2 inhibitors for the treatment of type 2 diabetes and their actual uptake in clinical practice.

Paradoxically, patients with CVD, heart failure, hypertension, CKD, and those at risk for hypoglycemia were less apt to receive an SGLT2 inhibitor than other patients.

“The relatively slow uptake of these agents is multifactorial,” Dr. Rangaswami said. “Cardiologists and nephrologists may suffer from some level of ‘therapeutic inertia’ when using new agents they are unfamiliar with and originally branded as ‘antidiabetic’ agents, with the perception of these agents being outside the scope of their practice.”

Two other factors are also at play. “The current health care system is based on ‘specialty silos,’ where specialists tend to stick to the traditional scope of their specialty and are reluctant to view these agents as part of their therapeutic armamentarium. Finally, insurance coverage barriers and affordability also limit the use on a widespread basis,” Dr. Rangaswami said.

For example, a large observational study published last year showed a “striking” discordance between evidence-based, guideline-recommended use of SGLT2 inhibitors for the treatment of type 2 diabetes and their actual uptake in clinical practice.

Paradoxically, patients with CVD, heart failure, hypertension, CKD, and those at risk for hypoglycemia were less apt to receive an SGLT2 inhibitor than other patients.

“The relatively slow uptake of these agents is multifactorial,” Dr. Rangaswami said. “Cardiologists and nephrologists may suffer from some level of ‘therapeutic inertia’ when using new agents they are unfamiliar with and originally branded as ‘antidiabetic’ agents, with the perception of these agents being outside the scope of their practice.”

Two other factors are also at play. “The current health care system is based on ‘specialty silos,’ where specialists tend to stick to the traditional scope of their specialty and are reluctant to view these agents as part of their therapeutic armamentarium. Finally, insurance coverage barriers and affordability also limit the use on a widespread basis,” Dr. Rangaswami said.

To protect the heart and kidneys, sodium-glucose transporter 2 (SGLT2) inhibitors and glucagonlike peptide–1 (GLP-1) receptor agonists should be considered for people with type 2 diabetes and chronic kidney disease (CKD), the American Heart Association advised in a new scientific statement.

Taken together, the results of relevant clinical trials indicate that SGLT2 inhibitors and GLP-1 receptor agonists safely and significantly reduce the risk for cardiovascular (CV) events, death, and the slow progression of CKD to end-stage kidney disease, including the risks for dialysis, transplantation, and death, the writing group says.

The scientific statement was published online Sept. 28 in Circulation.

“There has been rapid reporting of high-quality data in the cardio-renal-metabolic space with significant heart and kidney benefits, particularly with these two newer classes of antihyperglycemic agents,” Janani Rangaswami, MD, who chaired the writing group, said in an interview.

“More recent data show benefits in chronic kidney disease and heart failure even in patients without diabetes,” said Dr. Rangaswami, Einstein Medical Center and Sidney Kimmel Medical College, both in Philadelphia.

“These data are practice-changing in both cardiology and nephrology, and usher in a new era of disease-modifying therapies in heart and kidney disease,” Dr. Rangaswami added.
 

Recommendations at a glance

• Provide early and ongoing assessment of risks for CVD and CKD to patients who may benefit from SGLT2 inhibitors of GLP-1 receptor agonists.
• Tailor medication choices that meet the needs of individual patients. Realize that, given “consistent class-wide effects,” the choice of a specific SGLT2 inhibitor or GLP-1 receptor agonist may be dictated by affordability, coverage, and formulary considerations.
• Adjust all medications in tandem with these medicines and consider the burden of polypharmacy, which is common among people with type 2 diabetes. Adjust concomitant therapies and deprescribe where possible.
• Identify risks for hypoglycemia and educate patients on the signs so they can seek treatment quickly.
• Monitor and control high blood pressure.
• Counsel patients about the risks for and symptoms of euglycemic diabetic ketoacidosis when taking SGLT2 inhibitors, as well as classic DKA, which can be fatal.
• Regularly screen and counsel patients about foot care to prevent foot ulcers or blisters that can quickly become infected and lead to amputation.

The writing group identified two additional patient subgroups that may benefit from SGLT2 inhibitors and GLP-1 receptor agonists: those with heart failure with reduced ejection fraction with or without diabetes; and those with CKD who do not have diabetes. They say more data are anticipated to validate the use of SGLT2 inhibitors and GLP-1 receptor agonists in these “at-risk” patients.
 

Collaborative care model

The writing group proposed a collaborative care model, bridging cardiologists, nephrologists, endocrinologists, and primary care physicians, to help facilitate the “prompt and appropriate” integration of these new classes of medications in the management of patients with type 2 diabetes and CKD.

There is “an unmet need for a cardio-renal-metabolic care model that incorporates best practices in the real world to help align these therapies, especially with vulnerable high-risk patients with cardiorenal disease, and to overcome barriers toward uptake of these agents. Hopefully this statement provides some guidance to the cardiology and nephrology communities in that area,” Dr. Rangaswami said in an interview.

But old habits die hard, as research continues to show the slow adoption of these newer medications in the real world.

For example, a large observational study published last year showed a “striking” discordance between evidence-based, guideline-recommended use of SGLT2 inhibitors for the treatment of type 2 diabetes and their actual uptake in clinical practice.

I have been in practice for 31 years, so many of my patients are now in their 80s and 90s. Practices age with us, and I have been seeing many of these patients for 25-30 years. I have three rules I try to encourage my elderly patients follow, and I wanted to share them with you.

Absolutely, positively make sure you move!

Our older patients often have many reasons not to move, including pain from arthritis, deconditioning, muscle weakness, fatigue, and depression. “Keeping moving” is probably the most important thing a patient can do for their health.

Holme and Anderssen studied a large cohort of men for cardiovascular risk in 1972 and again in 2000. The surviving men were followed over an additional 12 years.¹ They found that 30 minutes of physical activity 6 days a week was associated with a 40% reduction in mortality. Sedentary men had a reduced life expectancy of about 5 years, compared with men who were moderately to vigorously physically active.

Stewart etal. studied the benefit of physical activity in people with stable coronary disease.² They concluded that, in patients with stable coronary heart disease, more physical activity was associated with lower mortality, and the largest benefit occurred in the sedentary patient groups and the highest cardiac risk groups.

Saint-Maurice et al. studied the effects of total daily step count and step intensity on mortality risk.³ They found that the risk of all-cause mortality decreases as the total number of daily steps increases, but that the speed of those steps did not make a difference. This is very encouraging data for our elderly patients. Moving is the secret, even if it may not be moving at a fast pace!
 

Never, ever get on a ladder!

This one should be part of every geriatric’s assessment and every Medicare wellness exam. I first experienced the horror of what can happen when elderly people climb when a 96-year-old healthy patient of mine fell off his roof and died. I never thought to tell him climbing on the roof was an awful idea.

Akland et al. looked at the epidemiology and outcomes of ladder-related falls that required ICU admission.⁴ Hospital mortality was 26%, and almost all of the mortalities occurred in older males in domestic falls, who died as a result of traumatic brain injury. Fewer than half of the survivors were living independently 1 year after the fall.

Valmuur et al. studied ladder related falls in Australia.⁵ They found that rates of ladder related falls requiring hospitalization rose from about 20/100,000 for men ages 15-29 years to 78/100,000 for men aged over 60 years. Of those who died from fall-related injury, 82% were over the age of 60, with more than 70% dying from head injuries.

Schaffarczyk et al. looked at the impact of nonoccupational falls from ladders in men aged over 50 years.⁶ The mean age of the patients in the study was 64 years (range, 50-85), with 27% suffering severe trauma. There was a striking impact on long-term function occurring in over half the study patients. The authors did interviews with patients in follow-up long after the falls and found that most never thought of themselves at risk for a fall, and after the experience of a bad fall, would never consider going on a ladder again. I think it is important for health care professionals to discuss the dangers of ladder use with our older patients, pointing out the higher risk of falling and the potential for the fall to be a life-changing or life-ending event.
 

Let them eat!

Many patients have a reduced appetite as they age. We work hard with our patients to choose a healthy diet throughout their lives, to help ward off obesity, treat hypertension, prevent or control diabetes, or provide heart health. Many patients just stop being interested in food, reduce intake, and may lose weight and muscle mass. When my patients pass the age of 85, I change my focus to encouraging them to eat for calories, socialization, and joy. I think the marginal benefits of more restrictive diets are small, compared with the benefits of helping your patients enjoy eating again. I ask patients what their very favorite foods are and encourage them to have them.

Keep your patients eating and moving, except not onto a ladder!

Patients with type 2 or type 1 diabetes who stay in a blood glucose range of 70-180 mg/dL at least 70% of the time have the lowest rates of major adverse coronary events, severe hypoglycemic episodes, and microvascular events, according to a post hoc analysis of data collected from 5,774 patients with type 2 diabetes.

Data collected by the DEVOTE trial showed that every additional 10% of the time that a patient with type 2 diabetes (T2D) spent in their target range for blood glucose linked with a significant 6% reduced rate for developing a major adverse cardiovascular event (MACE), Richard M. Bergenstal, MD, said at the virtual annual meeting of the European Association for the Study of Diabetes.

For every 10% increase in time in range (TIR), patients showed an average 10% drop in their incidence of severe hypoglycemic episodes.
 

Increasing evidence from post hoc analyses

These findings confirmed a prior post hoc analysis of data collected in the DCCT trial (NCT00360815), which were published in the New England Journal of Medicine, although those results showed significant relationships between increased TIR and decreased rates of retinopathy and microalbuminuria. For every 10% drop in TIR, retinopathy rose by 64% and microalbuminuria increased by 40%, according to a post hoc analysis of the DCCT data that Dr. Bergenstal helped run and was published in Diabetes Care.

“It’s becoming clear that time in range is an important metric for diabetes management, and our new findings and those previously reported with the DCCT data make it look like time in range is becoming a good marker for clinical outcomes as well,” said Dr. Bergenstal, an endocrinologist at the Park Nicollet Clinic in Minneapolis.

“It’s a new concept, getting time-in-range data,” said Dr. Bergenstal, who was a coauthor of recommendations from Diabetes Care that were made in 2019 by an expert panel organized by the Advanced Technologies & Treatments for Diabetes Congress. “We think this will be a good marker to keep glycemia in a safe range, and the results look positive.” Patients who stay in the blood glucose range of 70-180 mg/dL (3.9-10.0 mmol/L) at least 70% of the time generally have an hemoglobin A_1c of about 7%, which is what makes it a good target for patients and clinicians to focus on. Patients with a 50% TIR rate generally have an HbA_1c of about 8%.

But a TIR assessment can be more informative than HbA_1c, said the 2019 recommendations document. It called TIR assessments “appropriate and useful as clinical targets and outcome measurements that complement A1c for a wide range of people with diabetes.”
 

Data mining from DEVOTE

The analysis run by Dr. Bergenstal and his associates used data from 5,774 of the 7,637 patients enrolled in the DEVOTE trial, for whom adequate longitudinal blood glucose data were available to derive and track TIR. DEVOTE had the primary aim of comparing two different types of insulin in patients with T2D, according to its explanation in the New England Journal of Medicine. The DEVOTE patients did not undergo routine continuous blood glucose monitoring, so derivation of TIR was the only option with the dataset, Dr. Bergenstal said. “We’re trying to get continuous blood monitoring into T2D trials,” he said.

The post hoc analysis showed that, during the study’s follow-up of just under 2 years, patients who maintained a derived TIR of 70%-100% had about a 6% MACE rate, which peaked at nearly twice that in patients whose TIR was 30% or less. The analysis showed a roughly positive linear relationship between TIR and MACE rates across the range of TIR values. In an adjusted analysis, patients with at least a 70% TIR had a significant 31% lower rate of MACE events, compared with patients whose TIR was 50% or less.

A second analysis that looked for the association between TIR and incidence of hypoglycemic episodes showed a somewhat similar positive relationship, with incidence rates of severe hypoglycemia episodes of about 4%-5% among patients with a TIR of 70% or greater, and a rate of about 7% in patients with a TIR of 30% or less, spiking to 14% among patients with a TIR of 10% or less. In an adjusted analysis, patients with a TIR of at least 70% had a significant 46% lower rate of severe hypoglycemic events, compared with patients whose TIR was 50% or less. This finding belies a common misconception that the tighter glycemic control that produces a higher TIR will lead to increased episodes of severe hypoglycemia, Dr. Bergenstal noted.

He also reported less extensive data on microvascular events. In an adjusted analysis, patients with a TIR of at least 70% had a significant 40% cut in these events compared with patients with 50% or less TIR.

DEVOTE was funded by Novo Nordisk. Dr. Bergenstal has had financial relationships with Novo Nordisk and several other companies.

These findings confirmed a prior post hoc analysis of data collected in the DCCT trial (NCT00360815), which were published in the New England Journal of Medicine, although those results showed significant relationships between increased TIR and decreased rates of retinopathy and microalbuminuria. For every 10% drop in TIR, retinopathy rose by 64% and microalbuminuria increased by 40%, according to a post hoc analysis of the DCCT data that Dr. Bergenstal helped run and was published in Diabetes Care.

“It’s becoming clear that time in range is an important metric for diabetes management, and our new findings and those previously reported with the DCCT data make it look like time in range is becoming a good marker for clinical outcomes as well,” said Dr. Bergenstal, an endocrinologist at the Park Nicollet Clinic in Minneapolis.

“It’s a new concept, getting time-in-range data,” said Dr. Bergenstal, who was a coauthor of recommendations from Diabetes Care that were made in 2019 by an expert panel organized by the Advanced Technologies & Treatments for Diabetes Congress. “We think this will be a good marker to keep glycemia in a safe range, and the results look positive.” Patients who stay in the blood glucose range of 70-180 mg/dL (3.9-10.0 mmol/L) at least 70% of the time generally have an hemoglobin A_1c of about 7%, which is what makes it a good target for patients and clinicians to focus on. Patients with a 50% TIR rate generally have an HbA_1c of about 8%.

But a TIR assessment can be more informative than HbA_1c, said the 2019 recommendations document. It called TIR assessments “appropriate and useful as clinical targets and outcome measurements that complement A1c for a wide range of people with diabetes.”
 

Data mining from DEVOTE

The analysis run by Dr. Bergenstal and his associates used data from 5,774 of the 7,637 patients enrolled in the DEVOTE trial, for whom adequate longitudinal blood glucose data were available to derive and track TIR. DEVOTE had the primary aim of comparing two different types of insulin in patients with T2D, according to its explanation in the New England Journal of Medicine. The DEVOTE patients did not undergo routine continuous blood glucose monitoring, so derivation of TIR was the only option with the dataset, Dr. Bergenstal said. “We’re trying to get continuous blood monitoring into T2D trials,” he said.

The post hoc analysis showed that, during the study’s follow-up of just under 2 years, patients who maintained a derived TIR of 70%-100% had about a 6% MACE rate, which peaked at nearly twice that in patients whose TIR was 30% or less. The analysis showed a roughly positive linear relationship between TIR and MACE rates across the range of TIR values. In an adjusted analysis, patients with at least a 70% TIR had a significant 31% lower rate of MACE events, compared with patients whose TIR was 50% or less.

A second analysis that looked for the association between TIR and incidence of hypoglycemic episodes showed a somewhat similar positive relationship, with incidence rates of severe hypoglycemia episodes of about 4%-5% among patients with a TIR of 70% or greater, and a rate of about 7% in patients with a TIR of 30% or less, spiking to 14% among patients with a TIR of 10% or less. In an adjusted analysis, patients with a TIR of at least 70% had a significant 46% lower rate of severe hypoglycemic events, compared with patients whose TIR was 50% or less. This finding belies a common misconception that the tighter glycemic control that produces a higher TIR will lead to increased episodes of severe hypoglycemia, Dr. Bergenstal noted.

He also reported less extensive data on microvascular events. In an adjusted analysis, patients with a TIR of at least 70% had a significant 40% cut in these events compared with patients with 50% or less TIR.

DEVOTE was funded by Novo Nordisk. Dr. Bergenstal has had financial relationships with Novo Nordisk and several other companies.

Type 2 diabetes patients could lower their risk for death from any cause by up to a third by exercising at a moderate to high level or by cycling, according to data from two studies reported at the virtual annual meeting of the European Association for the Study of Diabetes.

Yun-Ju Lai, MD, and colleagues from the Puli branch of Taichung Veterans General Hospital in Nantou, Taiwan, found that persons with type 2 diabetes who exercised at moderate to high intensity had a 25%-32% decreased risk for death, compared with those who did not exercise.

In a separate study, Mathias Ried-Larsen, MSc, PhD, group leader at the Centre for Physical Activity Research, Rigshospitalet, Copenhagen, and associates found that cycling was associated with a 25%-31% decreased risk for all-cause death compared to no cycling, and that cycling also reduced cardiovascular mortality.
 

Results fit with ADA recommendations

“There is really nothing surprising about these results as others have shown that regular participation in physical activity lowers both overall mortality rates and morbidity,” commented Sheri Colberg-Ochs, PhD, professor emerita in exercise science at Old Dominion University in Norfolk, Va., in an interview.

“Regular exercise participation lowers the risk of mortality in almost all populations with many different health conditions. It is not specific to people with type 2 diabetes,” Dr. Colberg-Ochs said. “These data add further support to the ADA [American Diabetes Association] recommendations by again suggesting that being more active leads to many health benefits for people with type 2 diabetes.”

Dr. Colberg-Ochs, who was not involved in either study, is recognized by the ADA as an Outstanding Educator in Diabetes. She was also involved in writing the ADA’s position statement on physical activity/exercise in diabetes, which advocate that adults with type 2 diabetes should reduce sedentary time and undertake both aerobic and resistance exercise training to help optimize their glycemic and general health outcomes.
 

Asian population understudied

In an interview Dr. Lai acknowledged that epidemiologic studies had shown that exercise reduced the risk of cardiovascular events and mortality in subjects with type 2 diabetes. “However, the dose of exercise capacity for reducing mortality risk in people with type 2 diabetes was not yet well investigated, especially in the Asian population.”

Dr. Lai and colleagues analyzed data on 4,859 subjects drawn from two Taiwanese databases – the National Health Interview Survey and the National Health Insurance research database – to study what effect exercise “capacity” had on the risk for death in those with type 2 diabetes.

“Information about physical activity during leisure time was collected by asking the questions: ‘How often do you exercise every week? What kind of exercise do you do? How long do you do the exercise?’, Dr. Lai said. “We included nearly all kinds of exercise in the analysis, such as jogging, swimming, walking, dancing, riding, and so on.”

Each exercise had an activity intensity code expressed as kilocalories per minute. This was used to determine the exercise “capacity” by multiplying it by how frequently the exercise was performed per week and for how long each time.

“I don’t think ‘capacity’ is the right word to use here. The equation they used describes their exercise ‘volume,’ not their capacity. Self-reported exercise is notoriously inaccurate,” Dr. Colberg-Ochs observed. Furthermore, “just asking people how much they exercise and at what intensity [without using a validated exercise questionnaire] gives questionable results.”

The study’s findings, however, were clear: Those who exercised at a higher level had a significantly decreased risk for all-cause mortality than did those with no exercise habits. The hazard ratio for death by any cause was 0.75 for those who undertook a moderate level of exercise, burning 0-800 kcal per week. Exercising at a higher level burned more than 800 kcal had a HR of 0.68. A significant (P < .01) trend in favor of more exercise was noted.
 

Cycling reduces all-cause and cardiovascular mortality

In their prospective cohort study, Dr. Ried-Larsen and associates took a more specific look at the effects of exercise on mortality in diabetes by studying a single exercise: cycling. They sampled data on more than 5,000 people collected as part of the European Prospective Investigation into Cancer and Nutrition study. First, they identified participants with diabetes – although they couldn’t distinguish type 1 from type 2 forms because this was self-reported or obtained from registries. They then identified those who reported cycling at their baseline assessment and those who reported a change in cycling habits at their second examination around 5 years later.

At baseline, 38% of participants reported that they cycled every week. The mean age was 56 years, diabetes duration was 8 years, one-fifth were smokers, and the average body mass index was 29 kg/m².

Participants who reported cycling up to 1 hour every week at baseline had a 25% reduction in all-cause mortality, compared with those who did not cycle. The biggest reduction (31%) in all-cause mortality was seen for cycling 2.5-5 hours a week; cycling for 1-2.5 hours, and for more than 5 hours, yielded 23% and 24% risk reductions, respectively.

A reverse J–shaped relationship between cycling duration and reduction in all-cause mortality was seen, Dr. Ried-Larsen noted during a live oral session at the virtual meeting. “The maximum benefit [was at] around 5 hours per week, and the benefits persisted until around 9 hours per week.” Adjustment for the prevalence of stroke, MI, cancer, hyperlipidemia, hypertension, and central obesity did not alter the findings.

“The direction of the association was the same for cardiovascular mortality as all-cause mortality, although a bit weaker, with the maximum benefit being around 4 hours per week, and that persisted up until around 8 hours per week,” Dr. Ried-Larsen said.

The benefits of cycling on all-cause and cardiovascular mortality were lost, however, if those who cycled at baseline stopped by the second examination. Those who did not cycle at the first but did at the second examination got a benefit on both, as did those who continued cycling.

“Cycling is among one of the preferred activities for diabetes patients, so it actually may help them to achieve the recommend level of physical activity,” Dr. Ried-Larsen said.
 

Tailored exercise program important

Advice for exercise “should be tailored to the individual and based on starting fitness levels and activity levels,” Dr. Colberg-Ochs recommended.

“Those who are the most sedentary and the least fit have the most to gain from doing any activity. They should be advised to start out slowly and progress slowly with both aerobic activities and some resistance training,” Dr. Colberg-Ochs said.

She added: “In addition, individuals over 40 should engage in regular balance training, and all individuals should do some flexibility exercises.”

The studies received no commercial funding and all those mentioned in this article had no conflicts of interest to disclose.

The dramatically positive safety and efficacy results from the DAPA-CKD trial, which showed that treatment with the sodium-glucose transporter 2 (SGLT2) inhibitor dapagliflozin significantly cut both chronic kidney disease progression and all-cause death in patients with or without type 2 diabetes, were also notable for broadening the population of patients eligible for this treatment to those in the upper range of stage 4 CKD.

Courtesy European Society of Cardiology

Of the 4,304 CKD patients enrolled in DAPA-CKD, 624 (14%) had an estimated glomerular filtration rate (eGFR) of 25-29 mL/min per 1.73m², an unprecedented population to receive a drug from the SGLT2 inhibitor class in a reported study. The results provided definitive evidence for efficacy and safety in this range of renal function, said Hiddo J.L. Heerspink, Ph.D., at the virtual annual meeting of the European Association for the Study of Diabetes.

Until now, the widely accepted lowest level for starting an SGLT2 inhibitor in routine practice has been an eGFR as low as 30 mL/min per 1.73 m².
 

Using SGLT2 inhibitors when eGFR is as low as 25

“It’s time to reduce the eGFR level for initiating an SGLT2 inhibitor to as low as 25,” said Dr. Heerspink, a professor of clinical pharmacology at the University of Groningen (the Netherlands).

While conceding that this is primarily a decision to be made by guideline writers and regulatory bodies, he declared what he believed was established by the DAPA-CKD findings: “We’ve shown that dapagliflozin can be safely used in these patients. It is effective across the spectrum of kidney function.”

Other experts not associated with the study agreed.

Sara Freeman/MDedge News

The trial researchers were “brave” to enroll patients with eGFRs as low as 25 mL/min per 1.73 m², and “we urgently need these agents in patients with an eGFR this low,” commented Chantal Mathieu, MD, an endocrinologist and professor of medicine at Catholic University in Leuven, Belgium, and designated discussant for the report. Overall, she called the findings “spectacular,” a “landmark trial,” and a “winner.”

The study also set an new, lower floor for the level of albuminuria that can be usefully treated with dapagliflozin (Farxiga) by enrolling patients with a urinary albumin-to-creatinine ratio as low as 200 mg/g; the previous lower limit had been 300 mg/g, noted Dr. Mathieu. The new findings pose challenges to guideline writers, regulators who approve drug labels, and payers to a quickly make changes that will bring dapagliflozin to a wider number of patients with CKD.

Once the full DAPA-CKD results are reported, “it will change practice, and push the eGFR needle down” to as low as 25. It will also lower the albuminuria threshold for using dapagliflozin or other drugs in the class, commented David Z.I. Cherney, MD, a nephrologist at the University of Toronto. “It’s just one study,” he admitted, but the consistent renal benefits seen across several studies involving all four drugs in the SGLT2 inhibitor class will help hasten this change in identifying treatable patients, as well as expand the drug class to patients with CKD but no type 2 diabetes (T2D).

“I don’t think we’ve ever had stronger evidence” for drugs that can benefit both heart and renal function, plus the drug class is “very safe, and really easy to start” and maintain in patients, Dr. Cherney said in an interview. “It’s wonderful for these patients that we now have something new for treatment,” a drug with a “very favorable benefit-to-risk ratio.”
 

Results show many dapagliflozin benefits

While this broadening of the range of patients proven to tolerate and benefit from an SGLT2 inhibitor was an important consequence of DAPA-CKD, the study’s primary finding – that dapagliflozin was as safe and effective for slowing CKD progression in patients regardless of whether they also had T2D – will have an even bigger impact on expanding the target patient population. Showing efficacy in patients with CKD but without a T2D etiology, the status of about a third of the enrolled 4,304 patients, makes this treatment an option for “millions” of additional patients worldwide, said Dr. Heerspink. “These are the most common patients nephrologists see.” A major challenge now will be to do a better job finding patients with CKD who could benefit from dapagliflozin.

DAPA-CKD enrolled CKD patients based primarily on prespecified albuminuria and eGFR levels at more than 300 centers in 34 countries, including the United States. Virtually all patients, 97%, were on the only treatment now available with proven efficacy for slowing CKD, either an ACE inhibitor or an angiotensin receptor blocker. The small number of patients not on one of these drugs was because of poor tolerance.

The study’s primary endpoint was the combined rate of cardiovascular death, renal death, end-stage renal disease, or a drop in eGFR of at least 50% from baseline. This occurred in 14.5% of patients who received placebo and in 9.2% of those who received dapagliflozin during a median follow-up of 2.4 years, a highly significant 39% relative risk reduction. Concurrently with the report at the virtual meeting the results also appeared online in the New England Journal of Medicine. This 5.3% cut in the absolute rate of the combined, primary adverse outcome converted into a number needed to treat of 19 to prevent 1 event during 2.4 years, a “much lower” number needed to treat than reported for renin-angiotensin system inhibitors in these types of patients, Dr. Heerspink said.

Notable positive secondary outcomes included a significant 31% relative cut (a 2% absolute decline) in all-cause mortality, “a major highlight” of the findings, Dr. Heerspink said. Dapagliflozin treatment also linked with a significant 29% relative cut in the incidence of cardiovascular death or hospitalization for heart failure.

“Cardiovascular disease is the most common cause of death in patients with CKD,” explained David C. Wheeler, MD, a coinvestigator on the study and professor of kidney medicine at University College London. “The heart and kidney are intertwined. This is about cardiorenal disease.”

DAPA-CKD was funded by AstraZeneca, the company that markets dapagliflozin. Dr. Heerspink has been a consultant to and received research funding from AstraZeneca. He has also received personal fees from Mundipharma and Novo Nordisk, and he has also served as consultant to several other companies with the honoraria being paid to his institution. Dr. Mathieu has had relationships with AstraZeneca and several other companies. Dr. Cherney has been a consultant to and has received research funding from AstraZeneca and several other companies.

Once the full DAPA-CKD results are reported, “it will change practice, and push the eGFR needle down” to as low as 25. It will also lower the albuminuria threshold for using dapagliflozin or other drugs in the class, commented David Z.I. Cherney, MD, a nephrologist at the University of Toronto. “It’s just one study,” he admitted, but the consistent renal benefits seen across several studies involving all four drugs in the SGLT2 inhibitor class will help hasten this change in identifying treatable patients, as well as expand the drug class to patients with CKD but no type 2 diabetes (T2D).

“I don’t think we’ve ever had stronger evidence” for drugs that can benefit both heart and renal function, plus the drug class is “very safe, and really easy to start” and maintain in patients, Dr. Cherney said in an interview. “It’s wonderful for these patients that we now have something new for treatment,” a drug with a “very favorable benefit-to-risk ratio.”
 

Results show many dapagliflozin benefits

While this broadening of the range of patients proven to tolerate and benefit from an SGLT2 inhibitor was an important consequence of DAPA-CKD, the study’s primary finding – that dapagliflozin was as safe and effective for slowing CKD progression in patients regardless of whether they also had T2D – will have an even bigger impact on expanding the target patient population. Showing efficacy in patients with CKD but without a T2D etiology, the status of about a third of the enrolled 4,304 patients, makes this treatment an option for “millions” of additional patients worldwide, said Dr. Heerspink. “These are the most common patients nephrologists see.” A major challenge now will be to do a better job finding patients with CKD who could benefit from dapagliflozin.

DAPA-CKD enrolled CKD patients based primarily on prespecified albuminuria and eGFR levels at more than 300 centers in 34 countries, including the United States. Virtually all patients, 97%, were on the only treatment now available with proven efficacy for slowing CKD, either an ACE inhibitor or an angiotensin receptor blocker. The small number of patients not on one of these drugs was because of poor tolerance.

The study’s primary endpoint was the combined rate of cardiovascular death, renal death, end-stage renal disease, or a drop in eGFR of at least 50% from baseline. This occurred in 14.5% of patients who received placebo and in 9.2% of those who received dapagliflozin during a median follow-up of 2.4 years, a highly significant 39% relative risk reduction. Concurrently with the report at the virtual meeting the results also appeared online in the New England Journal of Medicine. This 5.3% cut in the absolute rate of the combined, primary adverse outcome converted into a number needed to treat of 19 to prevent 1 event during 2.4 years, a “much lower” number needed to treat than reported for renin-angiotensin system inhibitors in these types of patients, Dr. Heerspink said.

Notable positive secondary outcomes included a significant 31% relative cut (a 2% absolute decline) in all-cause mortality, “a major highlight” of the findings, Dr. Heerspink said. Dapagliflozin treatment also linked with a significant 29% relative cut in the incidence of cardiovascular death or hospitalization for heart failure.

“Cardiovascular disease is the most common cause of death in patients with CKD,” explained David C. Wheeler, MD, a coinvestigator on the study and professor of kidney medicine at University College London. “The heart and kidney are intertwined. This is about cardiorenal disease.”

The dramatically positive safety and efficacy results from the DAPA-CKD trial, which showed that treatment with the sodium-glucose transporter 2 (SGLT2) inhibitor dapagliflozin significantly cut both chronic kidney disease progression and all-cause death in patients with or without type 2 diabetes, were also notable for broadening the population of patients eligible for this treatment to those in the upper range of stage 4 CKD.

Of the 4,304 CKD patients enrolled in DAPA-CKD, 624 (14%) had an estimated glomerular filtration rate (eGFR) of 25-29 mL/min per 1.73m², an unprecedented population to receive a drug from the SGLT2 inhibitor class in a reported study. The results provided definitive evidence for efficacy and safety in this range of renal function, said Hiddo J.L. Heerspink, Ph.D., at the virtual annual meeting of the European Association for the Study of Diabetes.

Until now, the widely accepted lowest level for starting an SGLT2 inhibitor in routine practice has been an eGFR as low as 30 mL/min per 1.73 m².
 

Using SGLT2 inhibitors when eGFR is as low as 25

“It’s time to reduce the eGFR level for initiating an SGLT2 inhibitor to as low as 25,” said Dr. Heerspink, a professor of clinical pharmacology at the University of Groningen (the Netherlands).

While conceding that this is primarily a decision to be made by guideline writers and regulatory bodies, he declared what he believed was established by the DAPA-CKD findings: “We’ve shown that dapagliflozin can be safely used in these patients. It is effective across the spectrum of kidney function.”

Other experts not associated with the study agreed.

The trial researchers were “brave” to enroll patients with eGFRs as low as 25 mL/min per 1.73 m², and “we urgently need these agents in patients with an eGFR this low,” commented Chantal Mathieu, MD, an endocrinologist and professor of medicine at Catholic University in Leuven, Belgium, and designated discussant for the report. Overall, she called the findings “spectacular,” a “landmark trial,” and a “winner.”

The study also set an new, lower floor for the level of albuminuria that can be usefully treated with dapagliflozin (Farxiga) by enrolling patients with a urinary albumin-to-creatinine ratio as low as 200 mg/g; the previous lower limit had been 300 mg/g, noted Dr. Mathieu.

Further analyses from the cardiovascular outcome trial of the sodium-glucose transporter 2 inhibitor ertugliflozin in patients with type 2 diabetes helped better define positive effects the drug had on preserving renal function, and also gave a tantalizing hint that this drug, and hence possibly the entire SGLT2 inhibitor drug class, may benefit patients with heart failure with reduced ejection fraction.

But the underlying problem for ertugliflozin (Steglatro) – first seen when results from the VERTIS CV trial initially came out in June 2020 at the annual meeting of the American Diabetes Association – was that, while the trial met its primary endpoint of proving noninferiority to placebo for the combined endpoint of cardiovascular death, nonfatal MI, or nonfatal stroke, treatment with ertugliflozin showed no suggestion of benefit, compared with placebo for reducing this endpoint, producing a nonsignificant 3% relative cut in the combined rate of these adverse events, compared with placebo treatment.
 

‘Somewhat disappointing’ trial performance

Overall, results from VERTIS CV with ertugliflozin were “somewhat disappointing,” commented Melanie J. Davies, MD, who was not involved with the study and chaired a session at the virtual annual meeting of the European Association for the Study of Diabetes that reviewed the main results, put them into perspective, and added a few new exploratory analyses.

Although the results from 8,246-patient VERTIS CV (Evaluation of Ertugliflozin Efficacy and Safety Cardiovascular Outcomes Trial) put ertugliflozin in the same league as other drugs from its class for safety, “we do not see the significant benefits observed in many of the previous cardiovascular outcomes trials” for other drugs in the SGLT2 inhibitor class, specifically canagliflozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance), Dr. Davies said in an interview. The upshot, for at least the time being, is that ertugliflozin “is unlikely to receive a label for any new indications,” she predicted. In contrast, the other drugs in the class have, for example, received a U.S. labeled indication to reduce cardiovascular death (empagliflozin) or major cardiovascular disease events (canagliflozin) in adults with type 2 diabetes (T2D) and cardiovascular disease, or to reduce heart failure hospitalizations (dapagliflozin).

The main results from VERTIS CV, posted online in the New England Journal of Medicine after the EASD session, showed a single significant outcome difference between treatment with ertugliflozin and placebo over a median of 3.0 years of follow-up from among 10 reported secondary outcomes: a 30% relative reduction (a 1.1% absolute reduction) in the rate of hospitalization for heart failure, the sole criterion in the report by which ertugliflozin matched the benefits of the other SGLT2 inhibitors.

But the prespecified design of VERTIS CV called for a hierarchical sequence of secondary analyses. The statistically significant noninferiority of the primary endpoint allowed calculation of the initial secondary endpoint, a reduction in the combined rate of cardiovascular death or hospitalization for heart failure. Ertugliflozin treatment cut this outcome by a relative 12%, compared with placebo, a difference that was not significant.

This neutral finding brought to a stop further statistical testing of any of the other secondary endpoints, including impact on hospitalization for heart failure by itself. It also guaranteed that no beneficial effect inferred from the trial’s data would qualify for statistical validity, making it unlikely that ertugliflozin would gain any new label indications from these results. The drug carries a U.S. label that is limited to providing glycemic control.

Choosing among the SGLT2 inhibitors

“What we can say for sure is that there is a glycemic benefit and a heart failure hospitalization benefit” across all four of the SGLT2 inhibitors. “Beyond that, the best we can say today [about using these drugs in practice] is to follow regulatory indications and guidelines recommendations,” commented Javed Butler, MD, a cardiologist and professor and chair of medicine at the University of Mississippi Medical Center, Jackson.

“These results are going to lead to some serious discussions among the research, clinical, and regulatory communities about class effects versus drug effects, and specific trial data versus the totality of evidence,” he said in an interview.

“I think it will influence prescribing ertugliflozin, particularly in patients with established cardiovascular disease, or when the goal is to improve heart failure outcomes of reduce chronic kidney disease,” added Dr. Davies, a professor of diabetes medicine at the University of Leicester (England). “We already have positive benefits [proven for these outcomes] using other agents in the class.”

Perhaps one feature potentially in ertugliflozin’s favor is its price, and whatever impact that might have for payers or patients with inadequate coverage for their drug costs. U.S. websites show a typical retail price for ertugliflozin that is roughly 40% below the three other agents in the class, a difference that can add up to an annual cost savings of about $2,500.

A major consideration for clinicians deciding which SGLT2 inhibitor to prescribe should be “what can the patient afford,” noted Darren K. McGuire, MD, a coinvestigator for VERTIS CV, during discussion of the trial at the EASD virtual meeting.
 

New analyses show more renal-effect consistency

One surprise in the initial VERTIS CV report was in the study’s key renal outcome, a composite of renal death, need for dialysis, or a doubling of the serum creatinine level, which reflects a cut of at least a 50% in estimated glomerular filtration rate (eGFR). This composite outcome trended toward a significant benefit but fell short, producing a nominal 19% relative reduction. This combined endpoint probably “set the bar too high,” said David Z.I. Cherney, MD, a nephrologist who led the renal assessments run in the trial. He presented several exploratory analyses during the virtual EASD session that provided reassuring evidence that ertugliflozin was not an outlier among the SGLT2 inhibitors when it came to kidney benefits.

Perhaps the most compelling analysis he reported was a slight tweak to the main renal composite endpoint that substituted prevention of a 40% or greater reduction in eGFR for prevention of a 50% or greater reduction. By this somewhat lower bar for efficacy, treatment with ertugliflozin in VERTIS CV linked with a 34% relative risk reduction, compared with placebo (a roughly 1% absolute reduction) that was statistically significant, and importantly came out very close to the effect for this revised endpoint that had been seen for the other three SGLT2 inhibitor drugs.

Focusing on prevention of a 40% or greater drop in eGFR “gives a much more robust measure of renal protection,” Dr. Cherney, a clinician and researcher at the University of Toronto, said in an interview. “The key message is that renal protection is much more uniform” with the rest of the drugs in the class when looked at this way or by some of the other alternative parameters he reported. But the new renal analyses do not address disparities seen among the drugs in the class for several cardiovascular disease effects.

“The overall impression from VERTIS CV is that there was less cardiovascular disease benefit,” except for prevention of heart failure hospitalization, he said.

A teaser for HFpEF

One additional notable new finding discussed during the EASD session stemmed from the investigators ability to mine the medical records of enrolled patients for information about their heart failure history and left ventricular ejection fractions, a data set that was “unique,” compared with the other cardiovascular outcome trials for the drugs in the class, noted Francesco Cosentino, MD, another VERTIS CV coinvestigator and professor of cardiology at the Karolinska Institute in Stockholm.

Roughly a quarter of the enrolled patients had a history of heart failure, and about half of these patients had heart failure with preserved ejection fraction, about 1,000 total patients. In this subgroup treatment with ertugliflozin linked with a 30% relative reduction in hospitalization for heart failure, compared with placebo, a roughly 0.5% absolute reduction. The numbers were small and underpowered for producing convincing evidence, but it provided an intriguing hint of benefit for an unmet need that is currently undergoing further testing in studies designed to specifically explore benefit in this type of heart failure patient, said Dr. Cosentino.

Perhaps the most compelling analysis he reported was a slight tweak to the main renal composite endpoint that substituted prevention of a 40% or greater reduction in eGFR for prevention of a 50% or greater reduction. By this somewhat lower bar for efficacy, treatment with ertugliflozin in VERTIS CV linked with a 34% relative risk reduction, compared with placebo (a roughly 1% absolute reduction) that was statistically significant, and importantly came out very close to the effect for this revised endpoint that had been seen for the other three SGLT2 inhibitor drugs.

Focusing on prevention of a 40% or greater drop in eGFR “gives a much more robust measure of renal protection,” Dr. Cherney, a clinician and researcher at the University of Toronto, said in an interview. “The key message is that renal protection is much more uniform” with the rest of the drugs in the class when looked at this way or by some of the other alternative parameters he reported. But the new renal analyses do not address disparities seen among the drugs in the class for several cardiovascular disease effects.

“The overall impression from VERTIS CV is that there was less cardiovascular disease benefit,” except for prevention of heart failure hospitalization, he said.

A teaser for HFpEF

One additional notable new finding discussed during the EASD session stemmed from the investigators ability to mine the medical records of enrolled patients for information about their heart failure history and left ventricular ejection fractions, a data set that was “unique,” compared with the other cardiovascular outcome trials for the drugs in the class, noted Francesco Cosentino, MD, another VERTIS CV coinvestigator and professor of cardiology at the Karolinska Institute in Stockholm.

Roughly a quarter of the enrolled patients had a history of heart failure, and about half of these patients had heart failure with preserved ejection fraction, about 1,000 total patients. In this subgroup treatment with ertugliflozin linked with a 30% relative reduction in hospitalization for heart failure, compared with placebo, a roughly 0.5% absolute reduction. The numbers were small and underpowered for producing convincing evidence, but it provided an intriguing hint of benefit for an unmet need that is currently undergoing further testing in studies designed to specifically explore benefit in this type of heart failure patient, said Dr. Cosentino.

VERTIS CV was sponsored by Merck and Pfizer, the companies that market ertugliflozin. Dr. Davies has been a speaker on behalf of Merck and has had relationships with several other companies. Dr. Butler is a consultant to Merck and several other companies. Dr. McGuire has received honoraria from Merck, nonfinancial support from Pfizer, and has had relationships with several other companies.

Type 2 diabetes patients who had never used insulin showed sustained remission 10 years after bariatric surgery in a prospective study of 85 patients.

Having diabetes for less than 5 years was also predictive of achieving long-term diabetes remission, Diego Moriconi, MD, of the University of Pisa (Italy) and presenting study investigator, reported at the virtual annual meeting of the European Association for the Study of Diabetes.

“Weight loss was associated with type 2 diabetes remission 1 year after surgery, but it had no impact on the long-term relapse of diabetes,” Dr. Moriconi said.

The findings are important, commented Tina Vilsbøll, MD, DMSc, chief consultant at the Steno Diabetes Centre Copenhagen, who chaired the session. They’re important because they would help “to set the expectations for patients before they have surgery, what to expect in respect to resolution or remission of diabetes.”

If patients were taking insulin, for instance, the take home would seem to be not to expect too much in terms of remission of their diabetes, Dr. Vilsbøll said. She added: “Usually I am not a big fan of [relying on] diabetes duration, because often we know that patients with type 2 diabetes have had diabetes for a long time before they’re actually diagnosed.” However, “it seems to be very important here.”

Dr. Moriconi reported the findings of an observational study that had started in 2006 and recruited individuals about to undergo bariatric surgery for type 2 diabetes. Participants were evaluated before surgery and every 6-12 months after, undergoing various clinical and laboratory investigations, for a period of 10 years.

The majority of the recruited patients (76%) were women. Most (also 76%) had undergone gastric bypass (Roux-en-Y) surgery, and the remainder had undergone sleeve gastrectomy. Both types of surgery were equally as good at getting people into remission, as defined by the American Diabetes Association Standards of Medical Care in Diabetes, Dr. Moriconi said. As such, remission was achieved if the fasting blood glucose fell below 100 mg/dL and the hemoglobin A1c below 5.7%.

In the first year following surgery, 75% of patients had met diabetes remission criteria. This fell to 61% of patients after 5 years, and to 55% at 10 years. At each of these time points, 25% of patients had type 2 diabetes, with 14% relapsing back at 5 years and 20% at 10 years.

Dr. Moriconi pointed out some of the different characteristics of the 47 patients who had achieved diabetes remission at 10 years, compared with the 17 who had “relapsed” back to having type 2 diabetes and the 21 who had remained with type 2 diabetes.

The decrease in body mass index achieved at 10 years was no different between the three groups. However, 1 year after surgery, there had been a significantly greater drop in body in those who achieved remission, compared with those who did not (P = .04).

“Glycemic control improved with time in all the three groups after bariatric surgery, although more markedly so in the remission group,” Dr. Moriconi said.

He highlighted how none of the patients who had achieved remission had used insulin, whereas 12% of those who had relapsed and half (52%) of those who remained with type 2 diabetes had used insulin (P < .0001).

Patients who achieved remission at 1, 5, and 10 years were more likely to have had diabetes for less than 5 years than those who remained with type 2 diabetes. The average duration of diabetes was 2 years in those achieving remission versus 8 years in those who had relapsed and 13 years in those who had remained diabetic (P < .0001).

Logistic regression analysis, which adjusted for all major confounding factors such as age, sex, and type of surgery, showed that only the duration of diabetes and insulin therapy before surgery were the only predictors of long-term diabetes remission.

The study had no commercial funding. Dr. Moriconi and Dr. Vilsbøll had no conflicts of interest to disclose.

Not only the prevalence, but the impact of nonalcoholic fatty liver disease (NAFLD) is increasing in much of the world, Arun J. Sanyal, MD, said in a virtual presentation at the meeting jointly provided by Rutgers and Global Academy for Medical Education. “It is currently estimated that the number of people living with cirrhosis or with decompensated cirrhosis will increase two- to threefold from 2015 to 2030,” which underlines the public health impact and the need for improved treatment paradigms, he emphasized.

“The thing to remember about NAFLD is that it does not exist in a vacuum,” Dr. Sanyal said. NAFLD is a multisystem disorder. Most patients have concomitant cardiovascular disease, but others may have type 2 diabetes, hypertension, and dyslipidemia, all of which are now accepted as risk factors for nonalcoholic steatohepatitis (NASH), he said.

“What ties these conditions together is metabolic stress leading to systemic inflammation and fibrosis. This is primarily due to diet-induced obesity. If you think about treating all of these competing risks to the patient’s life, the optimal way is to treat the root cause,” he said.

Various options exist to manage the conditions that can lead to NASH, but several of these also appear promising as a treatment of NASH, Dr. Sanyal said. Glucagonlike peptide–1 agonists and sodium-glucose transporter 2 inhibitors have been shown to improve multiple outcomes of interest in type 2 diabetes. However, insulin can cause weight gain at the expense of controlling HbA1C levels, he said.

Bariatric surgery can improve histology, but many patients with advanced fibrosis do not demonstrate improvement in fibrosis. Also, bariatric surgery has its own associated morbidity, including an increased suicide rate across multiple studies, Dr. Sanyal noted.

A new and interesting option is duodenal mucosal resurfacing (DMR) “a novel, minimally invasive outpatient upper-endoscopic procedure,” said Dr. Sanyal. DMR involves use of a catheter to perform a submucosal lift and hydrothermal mucosal ablation, prompting healthy epithelial regrowth, he explained. “The mucosa sloughs off, fresh epithelium grows in, and the hormonal signal from the gut to the rest of the body is restored to a more normal pattern,” he noted.

In the REVITA-2 study of patients with diabetes and NAFLD, the average fat loss was 5.4% in those randomized to DMR vs. 2.4% in sham-procedure patients and represented “quite significant defatting of the liver,” Dr. Sanyal said.

Dr. Sanyal then focused on fatty liver disease. “The first step when you see a patient with fatty liver disease is to see how scarred is the liver, and whether the patient has silent cirrhosis. The more scarred the liver, the greater risk of liver-related outcomes,” he said. The goal of therapy for these patients is to reduce the risk of progression to cirrhosis, he added. Dr. Sanyal recommended evaluating fibrosis using the Fibrosis 4 score (Fib4). “If the Fib4 is less than 1.3, the likelihood of significant scarring in the liver is less than 10%,” he said. On the other hand, a Fib4 greater than 2.67 suggests advanced fibrosis, he noted.

Overall, the goals of treatment for NASH patients are to prevent cirrhosis, reduce decompensation, and prevent hepatocellular carcinoma, said Dr. Sanyal.

“The ideal drug for NASH should also help other end organs, or at least be neutral,” said Dr. Sanyal.

Current frontline therapies for precirrhotic NASH include thiazolidinediones (TZD), farnesoid X receptor (FXR)/fibroblast growth factor 19 (FGF-19), FGF21, thyroxine B-R, and glucagonlike peptide-1. Clinical evidence varies based on different populations, endpoints, assessment methods, and treatment duration, he said.

Looking ahead to the next decade, a NASH management paradigm will likely play out that can be applied in the clinic today, Dr. Sanyal said. First, make an initial assessment of the status of the end organs. Start with a weight-loss regimen; use statins and GLP-1 and SGLT2 inhibitors as needed. Follow and reassess, and if the patient still has disease, progress to targeted therapy for active NASH while continuing to encourage weight loss and healthy living, he said.

“The ultimate proof that what we are doing is working is that we are improving mortality, reducing health care costs, and improving patients’ function and quality of life,” he concluded.

Phase 2 data for the investigational, once-weekly basal insulin analog icodec (Novo Nordisk) showing comparable efficacy and safety to once-daily insulin glargine U100 have been published in the New England Journal of Medicine.

“Insulin icodec could potentially improve acceptance and likely would facilitate management in type 2 diabetes patients needing basal insulin, and I think it will be transformational in the way we manage people with type 2 diabetes requiring insulin,” said lead author Julio Rosenstock, MD, University of Texas Southwestern Medical Center, Dallas, who also presented the data at the virtual annual meeting of the European Association for the Study of Diabetes.

Insulin icodec binds to albumin to create a circulating depot with a 196-hour (8.1 days) half-life, so the once-weekly injection is designed to cover an individual’s basal insulin requirements for a full week, with steady insulin release. Because of its concentrated formulation, its injection volume is equivalent to that of daily glargine U100.

In the 26-week, randomized, phase 2 trial involving 247 insulin-naive patients with type 2 diabetes, once-weekly icodec’s glucose-lowering and safety profiles were similar to those of once-daily insulin glargine U100. These results were previously presented by Dr. Rosenstock in June at the virtual American Diabetes Association conference, as reported by Medscape Medical News.

In addition, new data in a poster at EASD 2020 showed that switching to icodec from other basal insulins is efficacious without causing significant hypoglycemia, as reported by Harpreet Bajaj, MD, MPH, director of the Leadership Sinai Centre for Diabetes, Mount Sinai Hospital, Toronto.

Charles M. Alexander, MD, an endocrinologist and managing director of Alexander Associates, Gwynedd Valley, Pa., said in an interview that “some patients will find once-weekly basal insulin an attractive option, while other patients will be indifferent to its availability.”

Dr. Alexander also pointed out that “payers are not going to be very interested in paying for a once-weekly basal insulin when daily basal insulins have been available for many years, unless the cost is the same or less. Resource-constrained health plans will wait until the price is [similar].”
 

The phase 2 study: Once weekly is just as good as daily

In the phase 2, randomized, double-blind, double-dummy, parallel-group, treat-to-target trial, the patients had baseline hemoglobin A1c levels of 7.0%-9.5% despite taking metformin, with or without a dipeptidyl peptidase–4 inhibitor.

They were randomized to weekly insulin icodec plus daily placebo (n = 125) or daily insulin glargine U100 plus weekly placebo (n = 122). The primary endpoint, change in A1c from baseline to week 26, dropped 1.33 percentage points with icodec and 1.15 percentage points with glargine, down to 6.7% and 6.9%, respectively. The difference wasn’t significant (P = .08). Fasting plasma glucose levels dropped by 58 mg/dL with icodec and 54 mg/dL with glargine (P = .34).

Time in range (70-140 mg/dL or 3.9-7.8 mmol/L) as assessed by flash glucose monitoring (FreeStyle Libre Pro) was greater with Icodec, by 5.4 percentage points, corresponding to an extra 78 minutes per day in range.

Mild hypoglycemia was more common with icodec than glargine (509 vs. 211 events per 100 patient-years, but rates of moderate/clinically significant hypoglycemia (52.5 vs. 46 per 100 patient-years, respectively) and severe hypoglycemia (1.4 vs. 0 per 100 patient-years) did not differ significantly (P = .85).

And the duration of hypoglycemia wasn’t longer with icodec, compared with glargine, despite its longer duration of action, Dr. Rosenstock emphasized.

Rates of other adverse events were similar between the groups.

Use of a once-weekly basal insulin could reduce the number of annual insulin injections from 365 to just 52, the authors noted in their paper.
 

New data: Switching to icodec is effective, safe

The new data on switching came from a 16-week, open-label, phase 2 trial of 154 patients with type 2 diabetes with insufficient glycemic control (mean A1c 7.9%) while taking oral medication and basal insulin. They were randomized to once-weekly icodec with or without an initial loading dose, or once-daily glargine U100.

Insulin doses were titrated weekly based on blood glucose levels as measured by continuous glucose monitoring (Dexcom G6).

The primary endpoint, time in range (70-180 mg/dL or 3.9-10.0 mmol/L) during weeks 15-16 was significantly better for icodec plus loading dose, compared with glargine U100 (72.9% vs 65.0%, P = .01) and similar between icodec and glargine U100 (66.0% vs 65.0%, P = .75).

Estimated mean percentage point reductions in A1c were 0.77 for icodec plus loading dose, 0.47 for icodec without the loading dose, and 0.54 for glargine U100.

Rates of moderate to severe hypoglycemia were similar between icodec plus loading dose and glargine U100 (78.0 and 79.4 events per 100 patient-years, respectively), and lower for icodec without the loading dose (14.8/100 patient-years).

There were no unexpected safety findings.

Novo Nordisk’s phase 3 trial for icodec is set to begin in late November.

The company is also developing a coformulation of icodec with its glucagonlike peptide–1 receptor agonist semaglutide, currently in phase 1 testing. Meanwhile, Eli Lilly is also developing a once-weekly basal analog, LY3209590, currently in phase 2 trials.

Dr. Alexander reported no relevant financial relationships.

Phase 2 data for the investigational, once-weekly basal insulin analog icodec (Novo Nordisk) showing comparable efficacy and safety to once-daily insulin glargine U100 have been published in the New England Journal of Medicine.

“Insulin icodec could potentially improve acceptance and likely would facilitate management in type 2 diabetes patients needing basal insulin, and I think it will be transformational in the way we manage people with type 2 diabetes requiring insulin,” said lead author Julio Rosenstock, MD, University of Texas Southwestern Medical Center, Dallas, who also presented the data at the virtual annual meeting of the European Association for the Study of Diabetes.

Insulin icodec binds to albumin to create a circulating depot with a 196-hour (8.1 days) half-life, so the once-weekly injection is designed to cover an individual’s basal insulin requirements for a full week, with steady insulin release. Because of its concentrated formulation, its injection volume is equivalent to that of daily glargine U100.

In the 26-week, randomized, phase 2 trial involving 247 insulin-naive patients with type 2 diabetes, once-weekly icodec’s glucose-lowering and safety profiles were similar to those of once-daily insulin glargine U100. These results were previously presented by Dr. Rosenstock in June at the virtual American Diabetes Association conference, as reported by Medscape Medical News.

In addition, new data in a poster at EASD 2020 showed that switching to icodec from other basal insulins is efficacious without causing significant hypoglycemia, as reported by Harpreet Bajaj, MD, MPH, director of the Leadership Sinai Centre for Diabetes, Mount Sinai Hospital, Toronto.

Charles M. Alexander, MD, an endocrinologist and managing director of Alexander Associates, Gwynedd Valley, Pa., said in an interview that “some patients will find once-weekly basal insulin an attractive option, while other patients will be indifferent to its availability.”

Dr. Alexander also pointed out that “payers are not going to be very interested in paying for a once-weekly basal insulin when daily basal insulins have been available for many years, unless the cost is the same or less. Resource-constrained health plans will wait until the price is [similar].”
 

The phase 2 study: Once weekly is just as good as daily

In the phase 2, randomized, double-blind, double-dummy, parallel-group, treat-to-target trial, the patients had baseline hemoglobin A1c levels of 7.0%-9.5% despite taking metformin, with or without a dipeptidyl peptidase–4 inhibitor.

They were randomized to weekly insulin icodec plus daily placebo (n = 125) or daily insulin glargine U100 plus weekly placebo (n = 122). The primary endpoint, change in A1c from baseline to week 26, dropped 1.33 percentage points with icodec and 1.15 percentage points with glargine, down to 6.7% and 6.9%, respectively. The difference wasn’t significant (P = .08). Fasting plasma glucose levels dropped by 58 mg/dL with icodec and 54 mg/dL with glargine (P = .34).

Time in range (70-140 mg/dL or 3.9-7.8 mmol/L) as assessed by flash glucose monitoring (FreeStyle Libre Pro) was greater with Icodec, by 5.4 percentage points, corresponding to an extra 78 minutes per day in range.

Mild hypoglycemia was more common with icodec than glargine (509 vs. 211 events per 100 patient-years, but rates of moderate/clinically significant hypoglycemia (52.5 vs. 46 per 100 patient-years, respectively) and severe hypoglycemia (1.4 vs. 0 per 100 patient-years) did not differ significantly (P = .85).

And the duration of hypoglycemia wasn’t longer with icodec, compared with glargine, despite its longer duration of action, Dr. Rosenstock emphasized.

Rates of other adverse events were similar between the groups.

Use of a once-weekly basal insulin could reduce the number of annual insulin injections from 365 to just 52, the authors noted in their paper.
