Vegetarians have more favorable levels of a number of biomarkers including cardiovascular-linked ones – total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein A and B – than meat eaters, according to results of the largest study of its kind to date.

Results of the cross-sectional, observational study of 178,000 participants were presented as an electronic poster at this year’s online European Congress on Obesity by Jirapitcha Boonpor of the Institute of Cardiovascular & Medical Sciences, University of Glasgow (Scotland).

“We found that the health benefits of becoming a vegetarian were independent of adiposity and other sociodemographic and lifestyle-related confounding factors,” senior author Carlos Celis-Morales, PhD, also from the University of Glasgow, said in an interview.

Total cholesterol and LDL cholesterol concentrations for vegetarians were 21% and 16.4% lower than in meat eaters. But some biomarkers considered beneficial – including vitamin D concentrations – were lower in vegetarians, while some considered unhealthy – including triglycerides and cystatin-C levels – were higher.  

Vegetarian diets have recently become much more popular, but there is insufficient information about the health benefits. Prior reports of associations between biomarkers and a vegetarian diet were unclear, including evidence of any metabolic benefits, noted Dr. Celis-Morales.

Importantly, participants in the study had followed a vegetarian or meat-eater diet for at least 5 years before their biomarkers in blood and urine were assessed.

“If you modify your diet, then, 2 weeks later, you can see changes in some metabolic markers, but changes in markers of cardiovascular disease will take 5-10 years,” he explained.
 

No single biomarker can assess health

Asked to comment on the findings, John C. Mathers, PhD, noted that they clearly confirm the importance of not reading any biomarker result in isolation.

Health is complex and individual markers tell you just part of the story,” said Dr. Mathers of the Human Nutrition Research Centre, Newcastle (England) University.

He says a vegetarian diet can be nourishing but cautioned that “just because someone excludes meat from their diet does not mean necessarily that they will be eating a healthy diet.”

“Some of the biomarker differences seen in this work – such as the lower concentrations of total cholesterol and LDL cholesterol, GGT [gamma-glutamyl transferase], and ALT [alanine transaminase] – are indicators that the vegetarians were healthier than the meat eaters. However, other differences were less encouraging, including the lower concentrations of vitamin D and higher concentrations of triglycerides and cystatin-C.”

Also reflecting on the results, Jose Lara Gallegos, PhD, senior lecturer in human nutrition at Northumbria University, Newcastle upon Tyne, England, said they support previous evidence from large studies such as the European Prospective Investigation into Cancer and Nutrition (EPIC), which showed that a vegetarian diet is associated with a lower risk of heart disease.

“A vegetarian diet might also be associated with lower risk for liver diseases such as nonalcoholic fatty liver disease,” Dr. Gallegos said, but added that some levels of biomarkers considered to be “healthy” were lower in the vegetarians, and it is important to remember that strictly restricted diets might be associated with potential risks of nutritional inadequacies.

“Other, less restrictive dietary patterns, such as a Mediterranean diet, are also associated with ... health benefits,” he observed.
 

Large data sample from the UK Biobank study

“Specifically, we wanted to know if vegetarians were healthier because they are generally leaner and lead healthier lives, or whether their diet specifically was responsible for their improved metabolic and cardiovascular health,” Dr. Celis-Morales explained.

Data were included from 177,723 healthy participants from the UK Biobank study who were aged 37-73 years and had reported no major dietary changes over the last 5 years. In total, 4,111 participants were self-reported vegetarians who followed a diet without red meat, poultry, or fish, and 166,516 participants were meat eaters.

Nineteen biomarkers related to diabetes, hypertension, cardiovascular diseases, cancer, and liver and renal function were included, and the associations between vegetarian diet and biomarkers, compared with meat eaters, were examined.

To minimize confounding, the findings were adjusted for age, sex, deprivation, education, ethnicity, smoking, total sedentary time, type of physical activity, alcohol intake, body mass index, and waist circumference.

Compared with meat eaters, vegetarians had significantly lower concentrations of 14 biomarkers, including total cholesterol (21% lower); LDL (16% lower); lipoprotein A (1% lower), lipoprotein B (4% lower), and liver function markers (GGT: 354% lower, and ALT: 153% lower), IGF-1 (134% lower), urate (122% lower), total protein (29% lower), creatinine (607% lower), and C-reactive protein (10% lower).

However, the researchers found that, compared with meat eaters, vegetarians had significantly higher concentrations of some unhealthy biomarkers, including triglycerides (15% higher) and cystatin-C (4% higher), and lower levels of some beneficial biomarkers including high-density lipoprotein (HDL) cholesterol (5% lower), vitamin D (635% lower), and calcium (0.7% lower).

No associations were found for hemoglobin A1c, systolic blood pressure, and aminotransferase.

“Some biomarkers, for example urate, were very low in vegetarians, and this served to verify our results because we expected meat eaters to have higher levels of urate,” remarked Dr. Celis-Morales.
 

Diet commitment and cardiovascular outcomes

Many people, whether vegetarians or meat-eaters, follow short-term diets, for example, the Atkins or the 5:2 diet, and often lack continuity switching from one diet to the next, or back to regular eating.  

“They are healthy, but they do not commit for long enough to make a difference to metabolic markers or potentially long-term health. In contrast, vegetarians are usually fully committed but the reasons behind this commitment might be a concern for the environment or animal welfare, for example,” Dr. Celis-Morales pointed out.

However, he added that many vegetarians replace the meat in their diet with unhealthy alternatives. “They often eat too much pasta or potatoes, or other high-energy food with low nutritional value.”

Having identified metabolic markers specific to long-term vegetarian diets, Dr. Celis-Morales wanted to know what happens to vegetarians’ long-term cardiovascular health. He analyzed and published these outcomes in a separate study published in December 2020.

“Over 9 years of follow-up, we have found that vegetarians have a lower risk in terms of myocardial infarction in the long-term, as well as other cardiovascular disease,” he reported.

Asked whether there was an optimum age or time in life to become a vegetarian to improve health, Dr. Celis-Morales explained that the healthier you are, the less likely you will reap the health benefits of dietary changes – for example to being a vegetarian.

“It is more likely that those people who have unhealthy lifestyle risk factors, such as smoking, and high consumption of high-energy foods or processed meat are more likely to see positive health effects,” he said.  

Lifestyle changes to improve cardiovascular outcomes are usually more likely to be required at 40 or 50 years old than at younger ages. He also noted that metabolic markers tend to show clear improvement at around 3 months after adopting a particular diet but improvements in disease outcomes take a lot longer to become evident.

Dr. Celis-Morales and his team are currently conducting a further analysis to understand if the vegetarian diet is also associated with a lower risk of cancer, depression, and dementia, compared with meat-eaters.

Dr. Celis-Morales, Dr. Mathers, and Dr. Gallegos have reported no relevant financial relationships.

The U.S. Food and Drug Administration has cleared the Bigfoot Unity Diabetes Management System, a cap device that connects to insulin pens and translates continuous glucose data into dosing recommendations, for use in individuals aged 12 and older.

The Bigfoot Unity System has three primary components – proprietary smart pen caps for both rapid- and long-acting insulin, a mobile app, and an integrated FreeStyle Libre 2 continuous glucose monitor (iCGM) sensor, which was FDA-cleared in June 2020 – that fit into the person’s dose-decision process when they need it throughout the day.

It allows the user to scan the FreeStyle Libre 2 sensor, displaying the user’s current glucose value, trend arrow, and recommended correction dose. The smart pen cap also directly displays the health care provider’s suggested meal insulin doses with the correction dose. In just a few steps the system gives the person with diabetes support to make real-time treatment decisions.

It also includes hypoglycemia alerts and is compatible with all major U.S. brands of rapid- and long-acting disposable insulin pens.  

Health care providers can monitor the patient’s data through a secure web portal called the Bigfoot Clinic Hub.

JDRF said in a statement it “applauds the U.S. FDA on its decision to provide clearance for the Bigfoot Unity Diabetes Management by Bigfoot Biomedical.”

The new system “fills a critical gap and brings benefits of automation and device interconnectedness to people with diabetes who rely on multiple daily injections to manage their blood sugar levels.” It is a “win for both the type 1 and type 2 diabetes communities as it broadens the options of treatment to alleviate daily burdens.”
 

Growing market for smart insulin pens

The device is the latest advance in the “smart pen” field of semiautomated insulin delivery in which pen and compatible devices, software, and platforms are teamed up in various combinations to provide easier insulin dosing for patients with diabetes who require multiple daily injections but don’t wear insulin pumps.

On May 6, 2021, Eli Lilly announced it had signed “strategic international agreements” with Dexcom, Glooko, MyDiabby Healthcare, and Roche to provide platforms or devices compatible with Lilly’s prefilled Tempo Pen, which is already available in several global markets, and the Tempo Smart Button, currently in late-stage development and pending CE mark.  

And in November 2020, Medtronic launched a new version of its smart insulin pen with integrated CGM called the InPen. The reusable insulin injector pen uses a smartphone app to calculate dosing of short-acting insulin based on CGM readings and allows users to view glucose readings and insulin dose information. It was originally launched in 2017 by Companion Medical, and the company was acquired by Medtronic in September 2020.

Novo Nordisk and Sanofi are also developing products in the smart pen space.

In 2016, results from the LEADER trial of liraglutide in patients with type 2 diabetes helped jump-start awareness of the potential role of this new class of drugs, the glucagonlike peptide–1 receptor agonists, for reducing cardiovascular events. The randomized, placebo-controlled trial enrolled more than 9000 patients at more than 400 sites in over 30 countries, and took nearly 6 years from the start of patient enrollment to publication of the landmark results.

In December 2020, an independent team of researchers published results from a study with a design identical to LEADER, but used data that came not from a massive, global, years-long trial but from already-existing numbers culled from three large U.S. insurance claim databases. The result of this emulation using real-world data was virtually identical to what the actual trial showed, replicating both the direction and statistical significance of the original finding of the randomized, controlled trial (RCT).

What if research proved that this sort of RCT emulation could reliably be done on a regular basis? What might it mean for regulatory decisions on drugs and devices that historically have been based entirely on efficacy evidence from RCTs?
 

Making the most of a sea of observational data

Medicine in the United States has become increasingly awash in a sea of observational data collected from sources that include electronic health records, insurance claims, and increasingly, personal-health monitoring devices.

The Food and Drug Administration is now in the process of trying to figure out how it can legitimately harness this tsunami of real-world data to make efficacy decisions, essentially creating a new category of evidence to complement traditional data from randomized trials. It’s an opportunity that agency staff and their outside advisors have been keen to seize, especially given the soaring cost of prospective, randomized trials.

Recognition of this untapped resource in part led to a key initiative, among many others, included in the 21st Century Cures Act, passed in December 2016. Among the Act’s mandates was that, by the end of 2021, the FDA would issue guidance on when drug sponsors could use real-world evidence (RWE) to either help support a new indication for an already approved drug or help satisfy postapproval study requirements.

The initiative recognizes that this approach is not appropriate for initial drug approvals, which remain exclusively reliant on evidence from RCTs. Instead, it seems best suited to support expanding indications for already approved drugs.

Although FDA staff have made progress in identifying the challenges and broadening their understanding of how to best handle real-world data that come from observing patients in routine practice, agency leaders stress that this complex issue will likely not be fully resolved by their guidance to be published later this year. The FDA released a draft of the guidance in May 2019.
 

Can RWE be ‘credible and reliable?’

“Whether observational, nonrandomized data can become credible enough to use is what we’re talking about. These are possibilities that need to be explained and better understood,” said Robert Temple, MD, deputy director for clinical science of the FDA Center for Drug Evaluation and Research.

“Since the 1970s, the FDA has recognized historical controls as legitimate, so it’s possible [for RWE] to be credible. The big test is when is it credible and reliable enough [to assess efficacy]?” wondered Dr. Temple during a 2-day workshop on the topic held mid-February and organized by Duke University’s Margolis Center for Health Policy.

“We’re approaching an inflection point regarding how observational studies are generated and used, but our evidentiary standards will not lower, and it will be a case-by-case decision” by the agency as they review future RWE submissions, said John Concato, MD, the FDA’s associate director for real-world evidence, during the workshop.

“We are working toward guidance development, but also looking down the road to what we need to do to enable this,” said Dr. Concato. “It’s a complicated issue. If it was easy, it would have already been fixed.” He added that the agency will likely release a “portfolio” of guidance for submitting real-world data and RWE. Real-world data are raw information that, when analyzed, become RWE.

In short, the FDA seems headed toward guidance that won’t spell out a pathway that guarantees success using RWE but will at least open the door to consideration of this unprecedented application.
 

Not like flipping a switch

The guidance will not activate acceptance of RWE all at once. “It’s not like a light switch,” cautioned Adam Kroetsch, MPP, research director for biomedical innovation and regulatory policy at Duke-Margolis in Washington, D.C. “It’s an evolutionary process,” and the upcoming guidance will provide “just a little more clarity” on what sorts of best practices using RWE the FDA will find persuasive. “It’s hard for the FDA to clearly say what it’s looking for until they see some good examples,” Dr. Kroetsch said in an interview.

What will change is that drug sponsors can submit using RWE, and the FDA “will have a more open-minded view,” predicted Sebastian Schneeweiss, MD, ScD, a workshop participant and chief of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital in Boston. “For the first time, a law required [the FDA] to take a serious look” at observational data for efficacy assessment.

“The FDA has had a bias against using RWE for evidence of efficacy but has long used it to understand drug safety. Now the FDA is trying to wrap its arms around how to best use RWE” for efficacy decisions, said Joseph S. Ross, MD, another workshop participant and professor of medicine and public health at Yale University, New Haven, Conn.

The agency’s cautious approach is reassuring, Dr. Ross noted in an interview. “There was worry that the 21st Century Cures Act would open the door to allowing real-world data to be used in ways that weren’t very reliable. Very quickly, the FDA started trying to figure out the best ways to use these data in reasonable ways.”
 

Duplicating RCTs with RWE

To help better understand the potential use of RWE, the FDA sponsored several demonstration projects. Researchers presented results from three of these projects during the workshop in February. All three examined whether RWE, plugged into the design of an actual RCT, can produce roughly similar results when similar patients are used.

A generally consistent finding from the three demonstration projects was that “when the data are fit for purpose” the emulated or duplicated analyses with RWE “can come to similar conclusions” as the actual RCTs, said Dr. Schneeweiss, who leads one of the demonstration projects, RCT DUPLICATE.

At the workshop he reported results from RWE duplications of 20 different RCTs using insurance claims data from U.S. patients. The findings came from 10 duplications already reported in Circulation in December 2020 (including a duplication of the LEADER trial), and an additional 10 as yet unpublished RCT duplications. In the next few months, the researchers intend to assess a final group of 10 more RCT duplications.

Workshop participants also presented results from two other FDA demonstration projects: the OPERAND program run by the Multi-Regional Clinical Trials Center of Brigham and Women’s Hospital and Harvard; and the CERSI program based at Yale and the Mayo Clinic in Rochester, Minn. Both are smaller in scale than RCT DUPLICATE, incorporate lab data in addition to claims data, and in some cases test how well RWE can emulate RCTs that are not yet completed.

Collectively, results from these demonstration projects suggest that RWE can successfully emulate the results of an RCT, said Dr. Ross, a coinvestigator on the CERSI study. But the CERSI findings also highlighted how an RCT can fall short of clinical relevance.

“One of our most important findings was that RCTs don’t always represent real-world practice,” he said. His group attempted to replicate the 5,000-patient GRADE trial of four different drug options added to metformin in patients with type 2 diabetes. One of the four options included insulin glargine (Lantus), and the attempt to emulate the study with RWE hit the bump that no relevant real-world patients in their US claims database actually received the formulation.

That means the GRADE trial “is almost meaningless. It doesn’t reflect real-world practice,” Dr. Ross noted.

Results from the three demonstration projects “highlight the gaps we still have,” summed up Dr. Kroetsch. “They show where we need better data” from observational sources that function as well as data from RCTs.

Still, the demonstration project results are “an important step forward in establishing the validity of real-world evidence,” commented David Kerr, MBChB, an endocrinologist and director of research and innovation at the Sansum Diabetes Research Institute in Santa Barbara, Calif.
 

‘Target trials’ tether RWE

The target trial approach to designing an observational study is a key tool for boosting reliability and applicability of the results. The idea is to create a well-designed trial that could be the basis for a conventional RCT, and then use observational data to flesh out the target trial instead of collecting data from prospectively enrolled patients.

Designing observational studies that emulate target trials allows causal inferences, said Miguel A. Hernán, MD, DrPH, a professor of biostatistics and epidemiology at the Harvard School of Public Health, Boston. Plugging real-world data into the framework of an appropriately designed target trial substantially cuts the risk of a biased analysis, he explained during the workshop.

However, the approach has limitations. The target trial must be a pragmatic trial, and the approach does not work for placebo-controlled trials, although it can accommodate a usual-care control arm. It also usually precludes patient blinding, testing treatments not used in routine practice, and close monitoring of patients in ways that are uncommon in usual care.

The target trial approach received broad endorsement during the workshop as the future for observational studies destined for efficacy consideration by the FDA.

“The idea of prespecifying a target trial is a really fantastic place to start,” commented Robert Ball, MD, deputy director of the FDA Office of Surveillance and Epidemiology. “There is still a whole set of questions once the trial is prespecified, but prespecification would be a fantastic step forward,” he said during the workshop.

Participants also endorsed other important steps to boost the value of observational studies for regulatory reviews, including preregistering the study on a site such as clinicaltrials.gov; being fully transparent about the origins of observational data; using data that match the needs of the target trial; not reviewing the data in advance to avoid cherry picking and gaming the analysis; and reporting neutral or negative results when they occur, something often not currently done for observational analyses.

But although there was clear progress and much agreement among thought leaders at the workshop, FDA representatives stressed caution in moving forward.
 

“No easy answer”

“With more experience, we can learn what works and what doesn’t work in generating valid results from observational studies,” said Dr. Concato. “Although the observational results have upside potential, we need to learn more. There is no easy answer, no checklist for fit-for-use data, no off-the-shelf study design, and no ideal analytic method.”

Dr. Concato acknowledged that the FDA’s goal is clear given the 2016 legislation. “The FDA is embracing our obligations under the 21st Century Cures Act to evaluate use of real-world data and real-world evidence.”

He also suggested that researchers “shy away from a false dichotomy of RCTs or observational studies and instead think about how and when RCTs and observational studies can be designed and conducted to yield trustworthy results.” Dr. Concato’s solution: “a taxonomy of interventional or noninterventional studies.”

“The FDA is under enormous pressure to embrace real-world evidence, both because of the economics of running RCTs and because of the availability of new observational data from electronic health records, wearable devices, claims, etc.,” said Dr. Kerr, who did not participate in the workshop but coauthored an editorial that calls for using real-world data in regulatory decisions for drugs and devices for diabetes. These factors create an “irresistible force” spurring the FDA to consider observational, noninterventional data.

“I think the FDA really wants this to go forward,” Dr. Kerr added in an interview. “The FDA keeps telling us that clinical trials do not have enough women or patients from minority groups. Real-world data is a way to address that. This will not be the death of RCTs, but this work shines a light on the deficiencies of RCTs and how the deficiencies can be dealt with.”

Dr. Kroetsch has reported no relevant financial relationships. Dr. Schneeweiss has reported being a consultant to and holding equity in Aetion and receiving research funding from the FDA. Dr. Ross has reported receiving research funding from the FDA, Johnson & Johnson, and Medtronic. Dr. Hernán has reported being a consultant for Cytel.

In 2016, results from the LEADER trial of liraglutide in patients with type 2 diabetes helped jump-start awareness of the potential role of this new class of drugs, the glucagonlike peptide–1 receptor agonists, for reducing cardiovascular events. The randomized, placebo-controlled trial enrolled more than 9000 patients at more than 400 sites in over 30 countries, and took nearly 6 years from the start of patient enrollment to publication of the landmark results.

In December 2020, an independent team of researchers published results from a study with a design identical to LEADER, but used data that came not from a massive, global, years-long trial but from already-existing numbers culled from three large U.S. insurance claim databases. The result of this emulation using real-world data was virtually identical to what the actual trial showed, replicating both the direction and statistical significance of the original finding of the randomized, controlled trial (RCT).

What if research proved that this sort of RCT emulation could reliably be done on a regular basis? What might it mean for regulatory decisions on drugs and devices that historically have been based entirely on efficacy evidence from RCTs?
 

Making the most of a sea of observational data

Medicine in the United States has become increasingly awash in a sea of observational data collected from sources that include electronic health records, insurance claims, and increasingly, personal-health monitoring devices.

The Food and Drug Administration is now in the process of trying to figure out how it can legitimately harness this tsunami of real-world data to make efficacy decisions, essentially creating a new category of evidence to complement traditional data from randomized trials. It’s an opportunity that agency staff and their outside advisors have been keen to seize, especially given the soaring cost of prospective, randomized trials.

Recognition of this untapped resource in part led to a key initiative, among many others, included in the 21st Century Cures Act, passed in December 2016. Among the Act’s mandates was that, by the end of 2021, the FDA would issue guidance on when drug sponsors could use real-world evidence (RWE) to either help support a new indication for an already approved drug or help satisfy postapproval study requirements.

The initiative recognizes that this approach is not appropriate for initial drug approvals, which remain exclusively reliant on evidence from RCTs. Instead, it seems best suited to support expanding indications for already approved drugs.

Although FDA staff have made progress in identifying the challenges and broadening their understanding of how to best handle real-world data that come from observing patients in routine practice, agency leaders stress that this complex issue will likely not be fully resolved by their guidance to be published later this year. The FDA released a draft of the guidance in May 2019.
 

Can RWE be ‘credible and reliable?’

“Whether observational, nonrandomized data can become credible enough to use is what we’re talking about. These are possibilities that need to be explained and better understood,” said Robert Temple, MD, deputy director for clinical science of the FDA Center for Drug Evaluation and Research.

“Since the 1970s, the FDA has recognized historical controls as legitimate, so it’s possible [for RWE] to be credible. The big test is when is it credible and reliable enough [to assess efficacy]?” wondered Dr. Temple during a 2-day workshop on the topic held mid-February and organized by Duke University’s Margolis Center for Health Policy.

“We’re approaching an inflection point regarding how observational studies are generated and used, but our evidentiary standards will not lower, and it will be a case-by-case decision” by the agency as they review future RWE submissions, said John Concato, MD, the FDA’s associate director for real-world evidence, during the workshop.

“We are working toward guidance development, but also looking down the road to what we need to do to enable this,” said Dr. Concato. “It’s a complicated issue. If it was easy, it would have already been fixed.” He added that the agency will likely release a “portfolio” of guidance for submitting real-world data and RWE. Real-world data are raw information that, when analyzed, become RWE.

In short, the FDA seems headed toward guidance that won’t spell out a pathway that guarantees success using RWE but will at least open the door to consideration of this unprecedented application.

Finerenone, an investigational agent from a new drug class, just scored a second pivotal trial win after showing significant benefit for slowing progression of diabetic kidney disease in patients with type 2 diabetes in the FIDELIO-DKD pivotal trial with more than 5,700 patients.

Top-line results from FIGARO-DKD showed significant benefit for the primary endpoint of cardiovascular death and nonfatal cardiovascular disease endpoints in a placebo-controlled trial with about 7,400 patients with type 2 diabetes, reported Bayer, the company developing finerenone in statement released on May 10, 2021.

Based on the FIDELIO-DKD results, finerenone is currently under review by the U.S. Food and Drug Administration for marketing approval as a treatment for patients with type 2 diabetes and chronic kidney disease. FIDELIO-DKD, in addition to the primary endpoint that focused on slowing progression of diabetic kidney disease, had a secondary endpoint that assessed the combined incidence on treatment of cardiovascular death, or nonfatal episodes of stroke, MI, or hospitalization for heart failure. Results from the study published in 2020 in the New England Journal of Medicine showed that finerenone was safe and effective for both endpoints.

In the current study, FIGARO-DKD, run at more than 1,000 sites in 47 countries, these endpoints flipped. The primary outcome was a composite of cardiovascular death or nonfatal cardiovascular disease events, and the secondary outcome was prevention of DKD progression.

Other than stating the results significantly fulfilled FIGARO-DKD’s primary endpoint of reducing the incidence of combined cardiovascular disease endpoints, the release gave no further outcome details. The release noted that the enrolled patient cohort in FIGARO-DKD included more patients with earlier-stage chronic kidney disease, compared with FIDELIO-DKD.

Finerenone is a first-in-class investigational nonsteroidal, selective mineralocorticoid receptor antagonist (MRA). As an MRA it shares certain activities with the steroidal MRAs spironolactone and eplerenone. But the absence of a steroidal structure means that finerenone does not cause steroidal adverse effects such as gynecomastia. Results in FIDELIO-DKD showed that finerenone caused more hyperkalemia than placebo, but the level of hyperkalemia that it causes relative to spironolactone or eplerenone remains uncertain.

Initiatives targeting hypoglycemia and insulin pen wastage could lead to dramatic cost savings in small community hospitals, new data suggest.

The two projects are part of a dedicated inpatient glucose management service led by Mihail (“Misha”) Zilbermint, MD, one of the few full-time endocrine hospitalists in the United States and one of even fewer who work at a small community hospital.

In 2019, Dr. Zilbermint and colleagues reported that their inpatient glucose management program resulted in a 27% reduction in length of stay and a 10.7% lower 30-day readmission rate. The projected cost savings for the period January 2016 to May 2017 was $953,578.

Dr. Zilbermint’s team has written two new articles that document cost savings for specific elements of the program; namely, a set of hospital-wide hypoglycemia prevention measures, and an initiative that reduced duplicate inpatient insulin pen dispensing.

About 1 in 4 people in U.S. hospitals have diabetes or hyperglycemia. Large academic hospitals have endocrine divisions and training programs, but 85% of people receive care at small community hospitals.

“There are management guidelines, but they’re not always followed ... That’s why I’ve been advocating for endocrine hospitalists to be deployed nationally,” Dr. Zilbermint said. He is chief and director of endocrinology, diabetes, and metabolism at Johns Hopkins Community Physicians at Suburban Hospital, Bethesda, Maryland.

Asked to comment on behalf of the Society of Hospital Medicine (SHM), Greg Maynard, MD, program lead for SHM’s Electronic Quality Improvement Programs, said that Suburban’s overall program goals align with those of the SHM.

“Dedicated inpatient glycemic control teams are very important and desirable to improve the quality and safety of care for inpatients with hyperglycemia and diabetes,” he said.

Regarding specific initiatives, such as those aimed at reducing hypoglycemia and insulin pen wastage, Dr. Maynard said, “All of these are feasible in a wide variety of institutions. The main barrier is getting the institutional support for people to work on these interventions. This series of studies can help spread the word about the positive return on investment.”

Another barrier – the current lack of publicly reported measures or pay-for-performance programs for hypoglycemia prevention and glycemic control – may soon change, added Dr. Maynard, who is also chief quality officer at the University of California, Davis, Medical Center.

“The National Quality Forum has endorsed new measures, and the CDC’s National Healthcare Safety Network is working on ways to augment those measures and embed them into their infrastructure,” he said.

Although SHM doesn’t specifically endorse full-time glycemic control hospitalists over endocrinology-trained glycemic control experts, “certainly hospitalists who accrue added training are very well positioned to be an important part of these interdisciplinary teams,” Dr. Maynard said.
 

‘The nurses were so afraid of hypoglycemia’

Tackling hypoglycemia was Dr. Zilbermint’s first priority when he started the glycemic management program at Suburban in late 2015.

“One of the most common complaints from the nurses was that a lot of their patients had hypoglycemia, especially in the ICU, when patients were placed on insulin infusion protocols ... Every time, the nurse would have to call the attending and ask what to do,” he explains.

In addition, Dr. Zilbermint says, there was no standard for treating hypoglycemia. A nurse in one unit would give two cups of juice, another a 50% dextrose infusion, or another, milk. Even more concerning, “the nurses were so afraid of hypoglycemia they would reflexively discontinue all insulin, including basal.”

So one of the new initiatives, led by Carter Shelton, MSHCM, an administrative fellow at the Medical University of South Carolina, Charleston, was to implement a set of hospital-wide hypoglycemia prevention measures, as described in an article published online April 21 in the Journal of Diabetes Science and Technology.
 

Inpatient hypoglycemia rate was cut nearly in half

This began in 2016, when the multidisciplinary Suburban Hospital Glucose Steering Committee identified four main causes of insulin-induced hypoglycemia (defined as a blood glucose level of ≤70 mg/dL in a patient who had received at least one dose of insulin in the past 24 hours) and devised solutions for each:

1. Lack of a unified hypoglycemia protocol. A formal, evidence-based, nurse-driven treatment protocol with clinical decision support in the electronic medical record was developed. The Suburban team adapted much of the protocol from one that had been recently implemented at the flagship Johns Hopkins Hospital, in Baltimore, Maryland.

According to that protocol, if patients are able to swallow, they are given 15 g or 30 g of carbohydrates in order to achieve a blood glucose level of 50 to 70 mg/dL and <50 mg/dL, respectively. Levels are checked 15 minutes later. Intravenous D50 or glucagon is reserved for patients who can’t swallow.

2. For patients in critical care, the insulin infusion protocol that had been in use set blood glucose targets of 80 to 110 mg/dL, which resulted in hypoglycemia in nearly every patient who received an insulin infusion. This protocol was changed to the currently recommended 140 to 180 mg/dL.

3. Most patients were managed with sliding-scale insulin, an outdated yet still widely used regimen whereby insulin is given based only on current blood glucose without accounting for carbohydrates consumed with meals and not corrected until the subsequent meal. This was changed so that nurses give insulin after the patient has consumed at least 50% of their meal carbohydrates.

4. Lack of hypoglycemia reporting. A glucometrics dashboard – now used throughout the Johns Hopkins system – was adopted to produce daily hypoglycemia reports in the EMR system that could be reviewed by the inpatient glucose management service to track quality metrics and plan further interventions.

Between Jan. 1, 2016, and Sept. 30, 2019, out of a total 49,315 patient-days, there were 2,682 days on which any hypoglycemia occurred and 874 days on which moderate hypoglycemia occurred (≤54 mg/dL). Type 2 diabetes accounted for 84.4% of the total patient-days; type 1 accounted for 4.4%.

The overall frequency of any hypoglycemia patient-days per month decreased from 7.5% to 3.9% during the study period (P = .001). This was significant for the patients with type 2 diabetes (7.4% to 3.8%; P < .0001) but not for those with type 1 diabetes (18.5% to 18.0%; P = .08).

Rates of moderate hypoglycemia also decreased significantly among the patients with type 2 diabetes (1.9% to 1.0%; P = .03) but not for those with type 1 diabetes (7.4% to 6.0%; P = .14).

On the basis of these rates in reducing hypoglycemia, in which the inpatient hypoglycemia rate was cut nearly in half, the estimated savings in cost of care to the hospital was $98,635 during the period of January 2016 to September 2019.
 

Reducing insulin pen waste by minimizing duplicate prescriptions

Suburban Hospital had been using insulin vials and syringes when Dr. Zilbermint first arrived there. He lobbied the administration to allow use of pens, because they’re easier to use and they reduce the risk for needlestick injuries. Nurses were educated and retrained monthly in their use.

The switch to pens – aspart (Novolog Flexpen) for bolus insulin and glargine (Lantus SoloSTAR) – took place in 2018. The cost of the aspart pen was $16.19, and the cost of glargine was $25.08. Each holds 300 units of insulin.

After the first month, the team noticed a large increase in expenses. A quality improvement project was devised to address the issue.

“We were dispensing sometimes three or four pens per person. That’s a lot. Each pen holds 300 units, so one pen should last the entire hospital stay of an average 4- or 5-day stay,” Dr. Zilbermint explained. “We had to figure out where we were bleeding the money and where the pens were going.”

When pens disappeared, the pharmacy would have to dispense new ones. One problem was that when patients were transferred from one unit to another, the pen would be left behind and the room would be cleaned. Sometimes the pens weren’t stored properly or were misplaced. Often, they’d end up in a nurse’s pocket.

The second intervention was led by Urooj Najmi, MD, of the American International School of Medicine, Atlanta, Georgia. A program was instituted to reduce duplicate inpatient insulin pen dispensing, as detailed in an article published in the same issue of the Journal of Diabetes Science and Technology.

Solutions to reduce duplicate pen dispensing included having pharmacy track daily insulin pen reports and monitor duplicate orders, with “do not dispense” instructions conveyed via the EMR system. All multidose medications, including insulin pens, were to be placed in patients’ bins at the nursing station, and nurses were instructed to look for patients’ insulin pens prior to their being transferred to another unit, rather than ask for a replacement pen.

From July 2018 to July 2019, 3,121 patients received insulin, of whom 95% received aspart and 47% received glargine. Of the 9,516 pens dispensed, 68% were for aspart and 32% were for glargine. During the study period, the number of pens dispensed per patient dropped from 2.2 to 1.2 for aspart and from 2.1 to 1.3 for glargine; differences were highly significant (P = .0002 and P = .0005, respectively).

The total amount of unnecessary dispensing during the first 4 months after initiating the pen implementation program was 58%. The average monthly cost was $11,820.68; the projected cost per year was $141,848.

Six months after the waste reduction strategies were implemented, monthly waste had dropped to 42%, translating to an estimated potential cost savings of $66,261 over 12 months.

Because Suburban Hospital doesn’t have an outpatient dispensing license, there is still wastage when patients are discharged, because they can’t take their pens home with them. That remains a challenge, Dr. Zilbermint noted.

The team is working on implementing automatic A1c testing for patients admitted with hyperglycemia who either have a history of diabetes or whose blood glucose level is >140 mg/dL. Dr. Zilbermint said, “it’s in the guidelines, but it’s not always done.”

Dr. Zilbermint is a consultant for Guidepoint. Dr. Maynard, Mr. Shelton, and Dr. Najmi have disclosed no relevant financial relationships.

The overall frequency of any hypoglycemia patient-days per month decreased from 7.5% to 3.9% during the study period (P = .001). This was significant for the patients with type 2 diabetes (7.4% to 3.8%; P < .0001) but not for those with type 1 diabetes (18.5% to 18.0%; P = .08).

Rates of moderate hypoglycemia also decreased significantly among the patients with type 2 diabetes (1.9% to 1.0%; P = .03) but not for those with type 1 diabetes (7.4% to 6.0%; P = .14).

On the basis of these rates in reducing hypoglycemia, in which the inpatient hypoglycemia rate was cut nearly in half, the estimated savings in cost of care to the hospital was $98,635 during the period of January 2016 to September 2019.
 

Reducing insulin pen waste by minimizing duplicate prescriptions

Suburban Hospital had been using insulin vials and syringes when Dr. Zilbermint first arrived there. He lobbied the administration to allow use of pens, because they’re easier to use and they reduce the risk for needlestick injuries. Nurses were educated and retrained monthly in their use.

The switch to pens – aspart (Novolog Flexpen) for bolus insulin and glargine (Lantus SoloSTAR) – took place in 2018. The cost of the aspart pen was $16.19, and the cost of glargine was $25.08. Each holds 300 units of insulin.

After the first month, the team noticed a large increase in expenses. A quality improvement project was devised to address the issue.

“We were dispensing sometimes three or four pens per person. That’s a lot. Each pen holds 300 units, so one pen should last the entire hospital stay of an average 4- or 5-day stay,” Dr. Zilbermint explained. “We had to figure out where we were bleeding the money and where the pens were going.”

When pens disappeared, the pharmacy would have to dispense new ones. One problem was that when patients were transferred from one unit to another, the pen would be left behind and the room would be cleaned. Sometimes the pens weren’t stored properly or were misplaced. Often, they’d end up in a nurse’s pocket.

The second intervention was led by Urooj Najmi, MD, of the American International School of Medicine, Atlanta, Georgia. A program was instituted to reduce duplicate inpatient insulin pen dispensing, as detailed in an article published in the same issue of the Journal of Diabetes Science and Technology.

Solutions to reduce duplicate pen dispensing included having pharmacy track daily insulin pen reports and monitor duplicate orders, with “do not dispense” instructions conveyed via the EMR system. All multidose medications, including insulin pens, were to be placed in patients’ bins at the nursing station, and nurses were instructed to look for patients’ insulin pens prior to their being transferred to another unit, rather than ask for a replacement pen.

From July 2018 to July 2019, 3,121 patients received insulin, of whom 95% received aspart and 47% received glargine. Of the 9,516 pens dispensed, 68% were for aspart and 32% were for glargine. During the study period, the number of pens dispensed per patient dropped from 2.2 to 1.2 for aspart and from 2.1 to 1.3 for glargine; differences were highly significant (P = .0002 and P = .0005, respectively).

The total amount of unnecessary dispensing during the first 4 months after initiating the pen implementation program was 58%. The average monthly cost was $11,820.68; the projected cost per year was $141,848.

Six months after the waste reduction strategies were implemented, monthly waste had dropped to 42%, translating to an estimated potential cost savings of $66,261 over 12 months.

Because Suburban Hospital doesn’t have an outpatient dispensing license, there is still wastage when patients are discharged, because they can’t take their pens home with them. That remains a challenge, Dr. Zilbermint noted.

The team is working on implementing automatic A1c testing for patients admitted with hyperglycemia who either have a history of diabetes or whose blood glucose level is >140 mg/dL. Dr. Zilbermint said, “it’s in the guidelines, but it’s not always done.”

Dr. Zilbermint is a consultant for Guidepoint. Dr. Maynard, Mr. Shelton, and Dr. Najmi have disclosed no relevant financial relationships.

For persons with obesity who lost a substantial amount of weight on a low-calorie diet, the combination of exercise and medication significantly improved weight-loss maintenance, and more so than either strategy alone, according to results of a randomized, head-to-head trial.

A year after starting moderate to vigorous exercise coupled with liraglutide treatment, study participants had a weight loss 9.5 kg more than those who received placebo and usual activity, study results show.

Reductions in both weight and fat loss seen with exercise and liraglutide was roughly twice as much as what was achieved at 1 year with the strategies of liraglutide or exercise alone, according to authors of the study, which appears in the New England Journal of Medicine .

Although the findings may not apply to those who can’t or won’t perform moderate to vigorous exercise, the intervention in this study was nevertheless feasible in this group of persons with obesity who had a very low level of fitness, according to the authors.
 

Hope for healthy weight loss maintenance

Investigator Signe S. Torekov, PhD, said in an interview that these results provide hope that more-intensive exercise regimens, with or without medication, can be useful and well accepted among individuals struggling with obesity.

“When we started our study, we were told, ‘you are never going to have people with obesity exercising that much, and for that long’ – but people were actually very happy about the exercise,” said Dr. Torekov, a professor in the department of biomedical sciences at the University of Copenhagen.

“If you actually set up a program where people are monitored and you have a feedback system, then exercise is an excellent component in obesity treatment that should be much more actively used – not only for its weight-lowering component, but also for improving health and quality of life,” she said in an interview.

Weight-management specialist John D. Clark, MD, PhD, said results of this study can be used to help inform patients about how successful different strategies incorporating exercise and medication may be following initial weight loss.

“When patients plateau on a consistent, calorie-restricted dietary plan, we can educate them and manage expectations about what options may be available to them after their initial weight loss,” said Dr. Clark, of the University of Texas, Dallas.

“If the patient’s goal specifically is weight loss at all costs, then I may suggest, ‘let’s consider liraglutide or liraglutide in combination with exercise,’ ” he said in an interview. “Exercise improves body composition, even if it may not on its own be as successful in the next phase of their weight-loss journey, as shown in this study.”
 

Obesity and weight-loss challenges

Although it’s not uncommon for obese patients to lose a large amount of weight, keeping the weight off is frequently a challenge unless the patient follows a structured weight maintenance program, according to Dr. Torekov and coauthors.

The rapid weight regain seen in many obese patients could be a result of reductions in total energy expenditure or increased appetite. Exercise is one strategy to sustain weight loss, though according to the authors, very few studies have looked at exercise in isolation to quantify its contribution to maintenance.

Accordingly, the present study sought to determine whether exercise, medication, or the combination thereof works best to keep weight off.

The study incorporated liraglutide, a GLP-1 receptor agonist indicated for chronic weight management, along with a reduced-calorie diet and increased physical activity, in adults with elevated body mass index and at least one weight-related comorbidity.

The investigator-initiated phase 3 trial included 215 adults with a body mass index of 32-43. Individuals with type 2 diabetes were excluded. All participants followed an 8-week, low-calorie diet comprising 800 calories per day.

Participants who lost 5% or more of their body weight were then randomized to 1 year of exercise plus liraglutide, exercise plus placebo, usual activity plus liraglutide, or usual activity plus placebo.

The exercise program – which was structured but flexible, according to investigators – included group exercise sessions that incorporated 30 minutes of indoor cycling and 15 minutes of circuit training 2 days each week. Participants wore heart rate monitors during exercise to make sure they reached targets for moderate to vigorous intensity.

Instructors trained in exercise physiology planned and monitored individualized exercise programs for each participant in the exercise-medication or exercise-only arms of the study.

Participants in all groups attended 12 one-on-one consultations where body weight was measured and dietetic support was provided.
 

Weight loss with exercise and medication

Out of 215 individuals enrolled in the study, 195 lost at least 5% of body weight and continued on to the randomized portion, the investigators reported. During the diet phase, they lost a mean of 13.1 kg, translating into a 12% mean reduction in body weight.

The mean frequency of exercise was 2.4 times per week in the exercise-plus-medication group and 2.5 times per week in the exercise-only group. About one-third of the exercise took place in the group sessions, and there was no difference in relative intensity between group and individual exercise regimens, the investigators said.

Individuals in the exercise plus medication group continued to lose more weight, such that, at the end of 1 year, the weight loss decreased even further, by a mean of –3.4 kg. By contrast, weight increased by a mean of 6.1 kg for the placebo group, adding up to a treatment difference of –9.5 kg (95% confidence interval, –13.1 to –5.9; P < .001), according to the report.

That treatment effect was also seen, but more muted, in the exercise- and liraglutide-only groups, at –4.1 kg and –6.8 kg, respectively.

A significant treatment effect was observed for exercise plus liraglutide, compared with exercise alone, at –5.4 kg (P = .004), while the treatment effect for the combination versus liraglutide alone was not significant at –2.7 kg (P = .13), the data show.

Body-fat reduction at 52 weeks was –3.9 percentage points for exercise plus liraglutide as compared with placebo, or roughly twice the reductions seen in the exercise- and liraglutide-alone groups, the investigators said, adding that the combination preserved lean mass.

Reductions in hemoglobin A1c, which are generally thought to reduce diabetes risk, were reduced in both the liraglutide and liraglutide-exercise combination group, according to their report.

The research was supported in part by grants from the Novo Nordisk Foundation.

The proportions of patients who visited a physician for diabetes care and received hemoglobin A1c testing, foot and eye exams, and cholesterol testing increased from 2005 to 2018. However, this increase was primarily among those aged 65 years and older, and therefore eligible for Medicare.

“Our study suggests that providing affordable health care coverage can help ensure people with diabetes get recommended care. We also found that patients who were not receiving recommended care were more likely to be younger, newly diagnosed with diabetes, and not on diabetes medication. Clinicians can pay more attention to these patient populations to improve recommended care delivery and prevent diabetes-related complications,” lead author Jung-Im Shin, MD, said in an interview.

The data predate the COVID-19 pandemic, which has also had major effects on delivery of diabetes care, added Dr. Shin of Johns Hopkins University, Baltimore.

“Routine visits to the doctor and important screenings for retinopathy or foot examination have been postponed. People with diabetes have had to reschedule or cancel nonurgent visits, some have lost ... insurance following unemployment, and many have avoided health care facilities out of fear. We are only just beginning to understand the consequences of the pandemic on the health of people with diabetes,” Dr. Shin noted.
 

Overall improvements seen only in those aged 65 and older

The data, from 4,069 adults aged 20 years and older from the 2005-2018 National Health and Nutrition and Examination Survey (NHANES), were published online April 16, 2021, in Diabetes Care.

Dr. Shin and colleagues defined receipt of diabetes care as meeting all of the following five criteria in the past 12 months, based on the ADA Standards of Care and NHANES data availability: seeing a primary doctor for diabetes care, receiving A1c testing, receiving a foot examination, receiving an eye examination, and receiving cholesterol testing.

Over the entire 13-year period, 29.2% of respondents reported having received all five components.

That proportion increased significantly over time, from 25.0% in 2005-2006 to 34.1% in 2017-2018 (P = .004). However, among the individual components, only receiving A1c testing increased significantly over time, from 64.4% to 85.3%, in all age groups (P < .001).

Moreover, when stratified by age, receipt of all five components only increased significantly among participants aged 65 and older, from 29.3% in 2005-2006 to 44.2% in 2017-2018 (P = .001).

The proportion remained unchanged among those aged 40-64 (25.2% to 25.8%; P =  .457) and showed a nonsignificant increase in those aged 20-39 (9.9% to 26.0%; P = .401).

In adjusted analyses, older age, higher income and education, health insurance, longer duration of diabetes, use of diabetes medications, and hypercholesterolemia were significantly associated with receipt of ADA guideline–recommended diabetes care.

Factors not found to be associated with care receipt included sex, race/ethnicity, body mass index, smoking status, A1c, hypertension, cardiovascular disease, chronic kidney disease, and depressive symptoms.

Participants who received ADA guideline–recommended care were significantly more likely to achieve A1c below 7.5% (adjusted odds ratio, 1.52), blood pressure less than 140/90 mm Hg (aOR, 1.47), and LDL cholesterol below 100 mg/dL (aOR, 1.47), and to receive cholesterol-lowering medication (aOR, 1.79).

Dr. Shin said that it will be “important to study the impact of COVID-19 on diabetes care when new data are available.”

The project was supported by a research grant from Merck to Johns Hopkins University. Shin has reported receiving a grant from the National Institute of Diabetes and Digestive and Kidney Diseases. Two coauthors are Merck employees.

Dr. Shin and colleagues defined receipt of diabetes care as meeting all of the following five criteria in the past 12 months, based on the ADA Standards of Care and NHANES data availability: seeing a primary doctor for diabetes care, receiving A1c testing, receiving a foot examination, receiving an eye examination, and receiving cholesterol testing.

Over the entire 13-year period, 29.2% of respondents reported having received all five components.

That proportion increased significantly over time, from 25.0% in 2005-2006 to 34.1% in 2017-2018 (P = .004). However, among the individual components, only receiving A1c testing increased significantly over time, from 64.4% to 85.3%, in all age groups (P < .001).

Moreover, when stratified by age, receipt of all five components only increased significantly among participants aged 65 and older, from 29.3% in 2005-2006 to 44.2% in 2017-2018 (P = .001).

The proportion remained unchanged among those aged 40-64 (25.2% to 25.8%; P =  .457) and showed a nonsignificant increase in those aged 20-39 (9.9% to 26.0%; P = .401).

In adjusted analyses, older age, higher income and education, health insurance, longer duration of diabetes, use of diabetes medications, and hypercholesterolemia were significantly associated with receipt of ADA guideline–recommended diabetes care.

Factors not found to be associated with care receipt included sex, race/ethnicity, body mass index, smoking status, A1c, hypertension, cardiovascular disease, chronic kidney disease, and depressive symptoms.

Participants who received ADA guideline–recommended care were significantly more likely to achieve A1c below 7.5% (adjusted odds ratio, 1.52), blood pressure less than 140/90 mm Hg (aOR, 1.47), and LDL cholesterol below 100 mg/dL (aOR, 1.47), and to receive cholesterol-lowering medication (aOR, 1.79).

Dr. Shin said that it will be “important to study the impact of COVID-19 on diabetes care when new data are available.”

The project was supported by a research grant from Merck to Johns Hopkins University. Shin has reported receiving a grant from the National Institute of Diabetes and Digestive and Kidney Diseases. Two coauthors are Merck employees.

The majority of children with type 1 diabetes who tested positive for SARS-CoV-2 were cared for at home and did well, according to the first report of outcomes of pediatric patients with type 1 diabetes and COVID-19 from the United States.

Most children who were hospitalized had diabetic ketoacidosis (DKA) and high hemoglobin A1c levels, the new report from the T1D Exchange Quality Improvement Collaborative indicates. Fewer than 2% required respiratory support, and no deaths were recorded.

The greatest risk for adverse COVID-19 outcomes was among children with A1c levels >9%. In addition, children of certain ethnic minority groups and those with public health insurance were more likely to be hospitalized.

The study, conducted by G. Todd Alonso, MD, of the University of Colorado, Barbara Davis Center, Aurora, and colleagues, was published online April 14 in the Journal of Diabetes..

“As early reports identified diabetes as a risk factor for increased morbidity and mortality with COVID-19, the findings from this surveillance study should provide measured reassurance for families of children with type 1 diabetes as well as pediatric endocrinologists and their care teams,” say Dr. Alonso and colleagues.
 

Disproportionate rate of hospitalization, DKA among Black patients

Initiated in April 2020, the T1D Exchange Quality Improvement Collaborative comprises 56 diabetes centers, of which 52 submitted a total of 266 cases involving patients younger than 19 years who had type 1 diabetes and who tested positive for SARS-CoV-2 infection. Those with new-onset type 1 diabetes were excluded from this analysis and were reported separately. The data were collected between April 9, 2020, and Jan. 15, 2021.

Of the 266 patients, 23% (61) were hospitalized, and 205 were not. There were no differences by age, gender, or diabetes duration.

However, those hospitalized were more likely to be Black (34% vs. 13% among White patients; P < .001) and to have public health insurance (64% vs. 41%; P < .001). They also had higher A1c levels than patients who were not hospitalized (11% vs. 8.2%; P < .001), and fewer used insulin pumps (26% vs. 54%; P < .001) and continuous glucose monitors (39% vs. 75%; P < .001).

Those hospitalized were also more likely to have hyperglycemia (48% vs. 28%; P = .007), nausea (33% vs. 6%; P < .001), and vomiting (49% vs. 3%; P < .001). Rates of dry cough, excess fatigue, and body aches/headaches did not differ between those hospitalized and those who remained at home.

The most common adverse outcome was DKA, which occurred in 72% (44) of those hospitalized.

The most recent A1c level was less than 9% in 82% of those hospitalized vs. 31% of those who weren’t (P < .001) and in 38 of the 44 (86%) who had DKA.

“Our data reveal a disproportionate rate of hospitalization and DKA among racial and ethnic minority groups, children who were publicly insured, and those with higher A1c. It is essential to find pathways for the most vulnerable patients to have adequate, equitable access to medical care via in person and telehealth services, to obtain and successfully use diabetes technology, and to optimize sick day management,” say Dr. Alonso and colleagues.

One child, a 15-year-old White boy, underwent intubation and was placed on a ventilator. His most recent A1c was 8.9%. Another child, a 13-year-old boy whose most recent A1c level was 11.1%, developed multisystem inflammatory syndrome of childhood.

The registry remains open.

The Food and Drug Administration has approved dapagliflozin (Farxiga, AstraZeneca) to reduce the risk for kidney function decline, kidney failure, cardiovascular death, and hospitalization for heart failure in adult patients with chronic kidney disease (CKD) at risk for disease progression.

“Chronic kidney disease is an important public health issue, and there is a significant unmet need for therapies that slow disease progression and improve outcomes,” said Aliza Thompson, MD, deputy director of the division of cardiology and nephrology at the FDA’s Center for Drug Evaluation and Research. “Today’s approval of Farxiga for the treatment of chronic kidney disease is an important step forward in helping people living with kidney disease.”

Dapagliflozin was approved in 2014 to improve glycemic control in patients with diabetes mellitus, and approval was expanded in 2020 to include treatment of patients with heart failure and reduced ejection fraction, based on results of the DAPA-HF trial.

This new approval in chronic kidney disease was based on results of the DAPA-CKD trial that was stopped early in March 2020 because of efficacy of the treatment.

DAPA-CKD randomly assigned 4,304 patients with CKD but without diabetes to receive either dapagliflozin or placebo. The full study results, reported at the 2020 annual congress of the European Society of Cardiology and simultaneously published in the New England Journal of Medicine, showed that, during a median of 2.4 years, treatment with dapagliflozin led to a significant 31% relative reduction, compared with placebo in the study’s primary outcome, a composite that included at least a 50% drop in estimated glomerular filtration rate, compared with baseline, end-stage kidney disease, kidney transplant, renal death, or cardiovascular death.

Dapagliflozin treatment also cut all-cause mortality by a statistically significant relative reduction of 31%, and another secondary-endpoint analysis showed a statistically significant 29% relative reduction in the rate of cardiovascular death or heart failure hospitalization.

“Farxiga was not studied, nor is expected to be effective, in treating chronic kidney disease among patients with autosomal dominant or recessive polycystic (characterized by multiple cysts) kidney disease or among patients who require or have recently used immunosuppressive therapy to treat kidney disease,” the FDA statement noted.

Dapagliflozin should not be used by patients with a history of serious hypersensitivity reactions to this medication, or who are on dialysis, the agency added. “Serious, life-threatening cases of Fournier’s Gangrene have occurred in patients with diabetes taking Farxiga.”

Patients should consider taking a lower dose of insulin or insulin secretagogue to reduce hypoglycemic risk if they are also taking dapagliflozin. Treatment can also cause dehydration, serious urinary tract infections, genital yeast infections, and metabolic acidosis, the announcement said. “Patients should be assessed for their volume status and kidney function before starting Farxiga.”

Dapagliflozin previously received Fast Track, Breakthrough Therapy, and Priority Review designations for this new indication.

Two new phase 2 studies show encouraging findings with the investigational once-weekly basal insulin analogue icodec (Novo Nordisk) for people with type 2 diabetes who require insulin.

Sara Freeman/MDedge News

Insulin icodec works by reversibly binding to albumin, which slows the release of the active insulin analogue. It has a half-life of about 1 week. The glucose-lowering effect is distributed nearly evenly over the course of that week.

Ildiko Lingvay, MD, of the University of Texas Southwestern Medical Center, Dallas, who is an author of both new articles, said: “A weekly insulin is a game changer that will decrease the treatment burden for patients while also improving compliance.”

She noted that these studies demonstrate optimal approaches to initiating treatment with icodec and serve “as the steppingstones for a large phase 3 clinical trial program that is currently ongoing ... which is designed to evaluate the efficacy of once-weekly insulin administration in patients with either type 1 or type 2 diabetes.”

Another advantage of the formulation, Dr. Lingvay pointed out in a press release from her institution, is that it could decrease the burden on caregivers of patients with diabetes who require insulin.

“For example, for patients who need help injecting, those living in long-term care facilities, and those with memory problems, a once-weekly insulin will facilitate treatment and decrease the burden on the care providers,” she explained.
 

Titration balances glycemic control with hypoglycemic risk reduction

The first phase 2 trial, published online April 19, 2021, in Diabetes Care, was an open-label, 16-week, treat-to-target study that involved 205 insulin-naive adults with type 2 diabetes whose hemoglobin A1c levels were 7%-10% while using oral glucose-lowering medications.

They were randomly assigned to one of three once-weekly icodec titration groups:

• Group A – Fasting glucose target of 80-130 mg/dL with adjustments ±21 units/wk
• Group B – Fasting glucose target of 80-130 mg/dL with ±28 units/wk
• Group C – Fasting glucose target of 70-108 mg/dL, adjusting by ±28 units/wk or to once-daily glargine U100 with a fasting glucose target of 80-130 mg/dL with adjustments of ±4 units/d

The percentage of time in the ideal glucose range of 70-180 mg/dL, assessed by continuous glucose monitoring during weeks 15-16, improved from baseline levels of 57.0%, 55.2%, 51.0% for groups A, B, and C, respectively, and from 55.3% for glargine to 76.6%, 83.0%, 80.9%, and 75.9%, respectively.

There were no unexpected safety problems. Hypoglycemia episodes of glucose levels <54 mg/dL occurred in 0.05, 0.15, 0.38, and 0.00 per patient-year for the four groups, respectively. None were severe (i.e., required assistance).

The titration for patients in group A (80-130 mg/dL, ±21 units/wk) yielded the best balance between glycemic control and risk for hypoglycemia, Dr. Lingvay and colleagues said.
 

Use of loading dose when switching to icodec improves time in range

In the other phase 2 trial, also published online April 19 in Diabetes Care, Harpreet S. Bajaj, MD, of Mount Sinai Hospital, Toronto, and colleagues, with Dr. Lingvay as a coauthor, examined two methods of switching to icodec. This multicenter, open-label, treat-to-target study included 154 patients with A1c levels of 7-10% who were already receiving basal insulin daily and at least one oral glucose-lowering medication.

Patients were randomly assigned to one of three treatment approaches: a 100% loading dose of icodec (only the first dose was doubled), no loading dose, or once-daily glargine.

The primary endpoint was time in range (70-180 mg/dL) during weeks 15 and 16. This was achieved with 72.9% of patients receiving the icodec loading dose, 66.0% of patients receiving icodec without the loading dose, and 65.0% of patients receiving daily glargine. The difference between the icodec loading-dose method and glargine was significant, Dr. Bajaj and colleagues reported.

The mean A1c level was reduced from an overall average of 7.9% at baseline to 7.1% in the icodec loading dose group and to 7.4% in both the no-loading-dose and glargine groups.

Rates of adverse events and hypoglycemic episodes did not differ significantly among the groups.

Previous phase 2 data showing that the efficacy and safety of icodec were comparable with that of once-daily insulin glargine U100 in 247 insulin-naive patients with type 2 diabetes were published in November 2020 in the New England Journal of Medicine and were presented at the European Association for the Study of Diabetes (EASD) 2020 Annual Meeting, as reported by this news organization.

Both studies were funded by Novo Nordisk. Dr. Lingvey has received research funding, advisory/consulting fees, or other support from Novo Nordisk, Eli Lilly, Sanofi, AstraZeneca, Boehringer Ingelheim, Janssen, Intercept, Intarcia, Target RWE, Merck, Pfizer, Novartis, GI Dynamics, Mylan, Mannkind, Valeritas, Bayer, and Zealand Pharma. Dr. Bajaj has received speaking fees from AstraZeneca, Eli Lilly, Janssen Pharmaceuticals, Merck, and Novo Nordisk and research funding paid to LMC Healthcare for serving as principal investigator on clinical trials from Amgen, AstraZeneca Boehringer Ingelheim, Ceapro Inc, Eli Lilly, Gilead Sciences, Janssen Pharmaceuticals, Kowa Pharmaceuticals, Madrigal Pharmaceuticals, Merck, Novo Nordisk, Sanofi, and Tricida.

This was achieved with 72.9% of patients receiving the icodec loading dose, 66.0% of patients receiving icodec without the loading dose, and 65.0% of patients receiving daily glargine. The difference between the icodec loading-dose method and glargine was significant, Dr. Bajaj and colleagues reported.

The mean A1c level was reduced from an overall average of 7.9% at baseline to 7.1% in the icodec loading dose group and to 7.4% in both the no-loading-dose and glargine groups.

Rates of adverse events and hypoglycemic episodes did not differ significantly among the groups.

Previous phase 2 data showing that the efficacy and safety of icodec were comparable with that of once-daily insulin glargine U100 in 247 insulin-naive patients with type 2 diabetes were published in November 2020 in the New England Journal of Medicine and were presented at the European Association for the Study of Diabetes (EASD) 2020 Annual Meeting, as reported by this news organization.

Two new phase 2 studies show encouraging findings with the investigational once-weekly basal insulin analogue icodec (Novo Nordisk) for people with type 2 diabetes who require insulin.

Insulin icodec works by reversibly binding to albumin, which slows the release of the active insulin analogue. It has a half-life of about 1 week. The glucose-lowering effect is distributed nearly evenly over the course of that week.

Ildiko Lingvay, MD, of the University of Texas Southwestern Medical Center, Dallas, who is an author of both new articles, said: “A weekly insulin is a game changer that will decrease the treatment burden for patients while also improving compliance.”

She noted that these studies demonstrate optimal approaches to initiating treatment with icodec and serve “as the steppingstones for a large phase 3 clinical trial program that is currently ongoing ... which is designed to evaluate the efficacy of once-weekly insulin administration in patients with either type 1 or type 2 diabetes.”

Another advantage of the formulation, Dr. Lingvay pointed out in a press release from her institution, is that it could decrease the burden on caregivers of patients with diabetes who require insulin.

“For example, for patients who need help injecting, those living in long-term care facilities, and those with memory problems, a once-weekly insulin will facilitate treatment and decrease the burden on the care providers,” she explained.
 

Titration balances glycemic control with hypoglycemic risk reduction

The first phase 2 trial, published online April 19, 2021, in Diabetes Care, was an open-label, 16-week, treat-to-target study that involved 205 insulin-naive adults with type 2 diabetes whose hemoglobin A1c levels were 7%-10% while using oral glucose-lowering medications.

They were randomly assigned to one of three once-weekly icodec titration groups:

• Group A – Fasting glucose target of 80-130 mg/dL with adjustments ±21 units/wk
• Group B – Fasting glucose target of 80-130 mg/dL with ±28 units/wk
• Group C – Fasting glucose target of 70-108 mg/dL, adjusting by ±28 units/wk or to once-daily glargine U100 with a fasting glucose target of 80-130 mg/dL with adjustments of ±4 units/d

The percentage of time in the ideal glucose range of 70-180 mg/dL, assessed by continuous glucose monitoring during weeks 15-16, improved from baseline levels of 57.0%, 55.2%, 51.0% for groups A, B, and C, respectively, and from 55.3% for glargine to 76.6%, 83.0%, 80.9%, and 75.9%, respectively.

There were no unexpected safety problems. Hypoglycemia episodes of glucose levels <54 mg/dL occurred in 0.05, 0.15, 0.38, and 0.00 per patient-year for the four groups, respectively. None were severe (i.e., required assistance).

The titration for patients in group A (80-130 mg/dL, ±21 units/wk) yielded the best balance between glycemic control and risk for hypoglycemia, Dr. Lingvay and colleagues said.
 

Use of loading dose when switching to icodec improves time in range

In the other phase 2 trial, also published online April 19 in Diabetes Care, Harpreet S. Bajaj, MD, of Mount Sinai Hospital, Toronto, and colleagues, with Dr. Lingvay as a coauthor, examined two methods of switching to icodec. This multicenter, open-label, treat-to-target study included 154 patients with A1c levels of 7-10% who were already receiving basal insulin daily and at least one oral glucose-lowering medication.

Patients were randomly assigned to one of three treatment approaches: a 100% loading dose of icodec (only the first dose was doubled), no loading dose, or once-daily glargine.

The primary endpoint was time in range (70-180 mg/dL) during weeks 15 and 16. This was achieved with 72.9% of patients receiving the icodec loading dose, 66.0% of patients receiving icodec without the loading dose, and 65.0% of patients receiving daily glargine. The difference between the icodec loading-dose method and glargine was significant, Dr. Bajaj and colleagues reported.

The mean A1c level was reduced from an overall average of 7.9% at baseline to 7.1% in the icodec loading dose group and to 7.4% in both the no-loading-dose and glargine groups.

Rates of adverse events and hypoglycemic episodes did not differ significantly among the groups.

Previous phase 2 data showing that the efficacy and safety of icodec were comparable with that of once-daily insulin glargine U100 in 247 insulin-naive patients with type 2 diabetes were published in November 2020 in the New England Journal of Medicine and were presented at the European Association for the Study of Diabetes (EASD) 2020 Annual Meeting, as reported by this news organization.
