It’s passé to think of the sodium-glucose cotransporter 2 (SGLT2) inhibitor drugs as agents that primarily treat hyperglycemia because their major clinical role has rapidly morphed into treating or preventing heart failure and chronic kidney disease.

This change suddenly thrust primary responsibility for prescribing these drug into the hands of cardiologists and nephrologists, though endocrinologists, diabetologists, and primary care physicians remain in the prescribing mix, experts agreed at the virtual annual scientific sessions of the American Diabetes Association.

“Glucose lowering plays little or no role in the cardiorenal protection from drugs in the sodium-glucose cotransporter 2 inhibitor class,” said David Z. Cherney, MD, a nephrologist and professor of medicine at the University of Toronto.

The SGLT2 inhibitor drugs “belong to cardiologists and nephrologists,” declared endocrinologist Yehuda Handelsman, MD, an endocrinologist and diabetes specialist who is medical director of The Metabolic Institute of America in Tarzana, Calif.

But therein lies a problem. “Cardiologists and nephrologists often say that they don’t want to start SGLT2 inhibitors because they do not want to interfere with the glucose reducing medications a patient takes,” Dr. Cherney added.

“Cardiologists are absolutely afraid to prescribe SGLT2 inhibitors,” claimed John J.V. McMurray MD, a professor of medical cardiology at the University of Glasgow. “Cardiologists need to talk with diabetologists about the importance of treating heart failure” in patients with type 2 diabetes (T2D), and diabetologists “need to help cardiologists understand how to use these and other effective glucose-lowering drugs that reduce cardiovascular disease risk,” said Dr. McMurray during the ADA sessions.

“I don’t think any medical specialty owns this drug class,” said Silvio E. Inzucchi, MD, professor of medicine at Yale University, New Haven, Conn., and director of the Yale Medicine Diabetes Center. “No permission is needed” from an endocrinologist for another specialist to prescribe an SGLT2 inhibitor to patients with T2D or to appropriate patients without diabetes, he maintained.

The need for greater involvement by cardiologists in prescribing SGLT2 inhibitors to patients with T2D was underscored in findings recently reported by Dr. Inzucchi and associates. They analyzed the physician encounters that patients with T2D had with cardiologists and endocrinologists during 2017 at two U.S. health systems: one centered around clinicians affiliated with Yale Medicine and Yale University, and a second with clinicians drawn from the staffs of the Saint Luke’s Health System, including Saint Luke’s Mid America Heart Institute in Kansas City, Mo.

During 2017, the two systems has outpatient encounters with 109,747 patients with T2D, who averaged 67 years of age and were roughly evenly split between women and men: 43% had prevalent cardiovascular disease, including 30% with coronary artery disease and 15% with heart failure. These patients had more than 110,000 physician visits, and the number of these consultations with a cardiologist was double the number with an endocrinologist, Dr. Inzucchi and associates recently reported (Cardiovasc Endocrinol Metab. 2020 Jun;9[2]:56-9).

Among the 30% of T2D patients with prevalent cardiovascular disease, the consultation rate with a cardiologist was four times greater than with an endocrinologist; among the 15% with heart failure, a visit with a cardiologist was nearly seven times more common that with an endocrinologist.

“Based on these data, cardiovascular specialists encouraging the use of these medications, or, if comfortable, actually prescribing these medications, would likely significantly hasten the adoption of evidence-based glucose-lowering therapies in those patients most apt to benefit from them,” concluded the study’s authors.

Dr. Cherney has been a consultant to or has received honoraria from AstraZeneca, Boehringer Ingelheim, Janssen, Lilly, Merck, Mitsubishi Tanabe Pharma, and Sanofi. Dr. Handelsman has been a consultant to or speaker on behalf of Amarin, Amgen, Applied Therapeutic, AstraZeneca, Boehringer Ingelheim, Esperion, Gilead, Janssen, Merck, Merck-Pfizer, Novo Nordisk, Regeneron, and Sanofi. Dr. McMurray’s employer, the University of Glasgow, received payments from AstraZeneca for his involvement in trials involving dapagliflozin. Dr. Inzucchi has been a consultant to or helped run trials for Abbott, AstraZeneca, Boehringer Ingelheim, Merck, Novo Nordisk, Sanofi/Lexicon, and vTv Therapeutics.

An online, lifestyle-based weight loss initiative known as the Balance After Baby (BAB) program is effective at reducing weight retention a year after birth among women with recent gestational diabetes.

Specifically, results of the study were positive in women of most ethnicities, bar those of a small group of Hispanic origin.

Jacinda Nicklas, MD, from the University of Colorado at Denver, Aurora, presented findings of the BAB trial during the virtual annual scientific sessions of the American Diabetes Association. She was coprincipal investigator alongside Ellen Seely, MD, from Brigham and Women’s Hospital, Boston.

“Looking at the entire population of women on the BAB program, there was a trend in weight loss from 6 weeks postpartum to 12 months (P = .09), and significantly less postpartum weight retention at 12 months (P = .04),” Dr. Nicklas said.

“Through this effect on postpartum weight retention, the BAB program has potential to delay or prevent development of type 2 diabetes in women with recent gestational diabetes, while the web-based, remote nature of the program is scalable and very relevant in current times,” she added. “However, the lack of efficacy in Hispanic women means it needs to be modified to be successful in this ethnic group.”

Frank Qian, MD, who also presented during the same session, said the BAB program has potential as a viable way of preventing both future pregnancy complications and the progression to overt type 2 diabetes in this high-risk population.

“Large-scale epidemiologic studies show us that weight gain from pregnancy is a major risk factor for long-term cardiometabolic risk, particularly for women with a history of gestational diabetes,” he observed. “In turn, it is critical to implement lifestyle interventions that can help women get as close to the weight they were before pregnancy as possible and keep that weight off.”
 

Postpartum weight retention a modifiable risk factor for type 2 diabetes

Current evidence shows that a large proportion of women who develop gestational diabetes go on to develop type 2 diabetes within 10 years and that women with a history of gestational diabetes are more likely to retain or gain weight postpartum.

Dr. Nicklas also pointed out that obesity and weight gain are the strongest modifiable risk factors for type 2 diabetes.

“We know from the Diabetes Prevention Program [DPP] that an intensive lifestyle program in women who had had gestational diabetes led to a 53% reduction in type 2 diabetes,” Dr. Nicklas noted.

However, she added there were barriers to adhering to the intensive DPP program – which required 16 one-on-one meetings in the first 24 weeks – including travel, as some participants lived quite remotely, or family responsibilities. Consequently, Dr. Nicklas and colleagues developed the BAB pilot trial, which involved web-based delivery with remote coaching.

The trial involved women with a history of gestational diabetes who were, on average, 7 weeks postpartum. The key outcome was weight at 12 months, compared with both 6-week postpartum weight and prepregnancy weight.

Based on encouraging results in the pilot trial – in which the intervention group showed significant weight loss from 6-week postpartum weight and in 12-month weight retention – a larger, two-site trial was initiated, the BAB Intervention randomized, controlled trial.

Outcome measures were the same as for the pilot study. The 181 participants were aged 18-45 years, had recent gestational diabetes, and had a mean prepregnancy body mass index of approximately 29 kg/m². Around half were college educated, and 28% were from lower income households. Overall, 48% were white, 22% Asian, 17% African American, and 13% were of other ethnicities, with just over a third being Hispanic.

The initial study visit was at 6 weeks postpartum. Women were randomized to the behavioral intervention website plus a lifestyle coach group or to a control group that consisted of a website plus knowledge links.

The intervention website required women to complete some DPP-derived and bonus modules, and also featured action plans, tracked weight and steps, and had a direct link to contact their lifestyle coach. Follow-up visits were held at 6 and 12 months and A1c, waist circumference, and height/weight were measured. A total of 86% eligible women completed the 6- and 12-month visits.

Why didn’t the BAB program work in Hispanic women?

“The overall result showed that weight change from 6 weeks postpartum to 12 months revealed a slight gain in the control group of 1.3 pounds and a loss in the intervention group of 1.8 pounds, resulting in a between-group difference of 3.1 pounds [P = .09],” reported Dr. Nicklas. Adjustment for gestational weight gain and breastfeeding had no substantial effect.

When 12-month weight retention versus prepregnancy weight was assessed, the former was halved in participants in the BAB program.

The control group gained a mean of 10.1 pounds, and those in the intervention group gained a mean of 5.3 pounds, equivalent to a difference of 4.8 pounds (P = .04).

A prespecified analysis was conducted of 120 non-Hispanic women. At 12 months, weight retention, compared with prepregnancy weight showed an increase of 9 pounds in the control group versus 1.8 pounds in the intervention group (P = .01).

By comparison, in the small group of Hispanic women only, weight retention at 12 months compared to prepregnancy weight showed a 12.7-pound increase and a 13.3-pound increase in the control and intervention groups respectively, reported Dr. Nicklas.

Addressing the key question of why the BAB program was ineffective in Hispanic women, Dr. Nicklas said, “The literature tells us that low income Hispanic women are twice as likely to experience postpartum weight retention compared to white non-Hispanic women. But we also know that low-income Hispanic women generally engage less with interventions, and there is a higher acceptance of overweight among this ethnic group.”

The researchers hope to follow the women from their trial to determine who progresses to type 2 diabetes.

“Hispanic women are a high-risk population for gestational diabetes and type 2 diabetes, and we plan to identify the best options to help Hispanic women with a history of gestational diabetes prevent type 2 diabetes,” Dr. Nicklas said in an interview.

Dr. Qian also remarked on the differences observed in the weight loss outcomes for non-Hispanic versus Hispanic women, noting that it highlights the importance of studying lifestyle interventions in diverse populations. “Environmental and cultural factors that may differ across different racial or ethnic groups could impact the effectiveness of such interventions.

Dr. Nicklas and Dr. Qian have reported no relevant financial relationships.

Some automated insulin delivery systems currently in development add glucagon and/or pramlintide to insulin, but whether the extra hormones are worth the additional cost and effort is a subject of debate.

Sara Freeman/MDedge News

Also called closed-loop or artificial pancreas systems, they are comprised of an insulin pump and a continuous glucose monitor (CGM) that communicate via a built-in algorithm to deliver insulin based on glucose levels. Currently available systems are called hybrid closed loops because they still require user input for meals, exercise, illness, and other special circumstances.

Two hybrid closed-loop systems available in the United States, the Medtronic Minimed 670G and the Tandem Control-IQ, as well as the Medtronic Minimed 780G that was just approved in Europe, use insulin only.

Of all ongoing active closed-loop clinical studies, 44 involve insulin-only systems, as of May 2020.

However, two such systems in development add a glucagon analogue to insulin in the same pump (in separate cartridges), with the aim of minimizing the risk of hypoglycemia. And four investigational systems combine insulin with pramlintide (Symlin, AstraZeneca), an amylin analogue that reduces postmeal glucose spikes. Three systems in development combine all three hormones. 

In a debate during the virtual American Diabetes Association 80th Scientific Sessions, Roman Hovorka, PhD, of the University of Cambridge (England) argued in favor of insulin-only systems on the basis of efficacy, less burden and complexity, and lower cost.

But Steven J. Russell, MD, PhD, of Massachusetts General Hospital, Boston, countered that glucagon adds safety and value to the system by allowing for more aggressive insulin dosing with lower hypoglycemia risk, benefits which he said would overcome any downsides.
 

Insulin-only systems are good enough

Dr. Hovorka began by defining a “good” artificial pancreas as one that produces consensus time-in-range targets of at least 70% of glucose values between 3.9 to 10 mmol/L (70-180 mg/dL) and less than 3% below 3.9 mmol/L (70 mg/dL). At the same time, he said, the burden should be low, which he suggested means no more than 10-20 minutes a day spent managing the system, low “alarm burden,” and minimal technical issues.

“We need to balance glucose control and the burden. For some people, reducing the burden is sometimes even more important than the glucose control,” Dr. Hovorka commented.

He pointed out that, in addition to Medtronic’s and Tandem’s systems, two other insulin-only hybrid closed-loop systems are marketed outside the United States. These are the CamDiab system, available in the United Kingdom, which uses his group’s Cambridge control algorithm in a Dana pump with the Dexcom G6 sensor, and the Diabeloop algorithm, available in Europe, that combines a patch pump with the Dexcom G6.

“Lots of energy and resources are going to taking [insulin-only] systems into clinic use,” Dr. Hovorka observed.

He reviewed recently published data for both the Tandem Control-IQ and the Cambridge control algorithm showing similar results meeting the “good artificial pancreas” definition.

In his current clinic population of 160 patients aged 2-80 years using the Cambridge algorithm, 69% of users have achieved 70% or greater time in range and 28% have achieved 80% or greater time in range.

“So, the insulin-only system can achieve acceptable, and in some instances very good, glucose control,” Dr. Hovorka said.

He acknowledged that there are still challenges with insulin-only systems, including exercise-related dysglycemia and postprandial hyperglycemia related to slow insulin absorption, missed or incorrect boluses, or large meals.

But, Dr. Hovorka said, downsides of dual-hormone systems include the need for room-temperature stable glucagon and for dual-chamber pumps with two cannulas and two infusion sites (in addition to the sensor site), and the unknown long-term biological risks of chronic subcutaneous glucagon or pramlintide delivery.

Moreover, he said, costs are expected to be higher for a two-chamber versus single-chamber pump, as well as for the second hormone, reservoir, and infusion set.

Data thus far from short-term studies suggest that insulin-only systems are sufficient in eliminating nocturnal hypoglycemia, while the addition of glucagon potentially reduces daytime hypoglycemia, especially during exercise.

However, longer-term head-to-head studies will be needed, Dr. Hovorka said, noting, “Comparative benefits of the single- and dual-hormone system for improving hemoglobin A1c and preventing severe hypoglycemia remain unknown.”

He suggested that glucagon dual-hormone closed-loop systems might be suitable for patients who are particularly prone to hypoglycemia, whereas pramlintide dual-hormone systems have the potential to more fully close the loop when used with ultra rapid-acting insulin analogues.

Nonetheless, he said, “Many, if not most, users may achieve acceptable control with insulin-only systems.”

Dual-hormone systems: Extra benefit worth it?

Dr. Russell, who is an investigator in multicenter pivotal studies of both insulin-only and bihormonal configurations of the Beta Bionics iLet bionic pancreas, began his debate presentation by endorsing the effectiveness of insulin-only hybrid systems and stating that he encourages his patients with type 1 diabetes to use them.

But, he said, adding glucagon can allow for better automation of hypoglycemia prevention and treatment in situations such as exercise.

“A bihormonal system achieves lower glucose, higher time-in-range, and less hypoglycemia than a well-functioning insulin-only system.”

Moreover, Dr. Russell said, “Glucagon reduces the need for medicinal carbohydrates, promotes satiety, and increases energy expenditure. ... Combined, these three factors may oppose weight gain or encourage weight loss as opposed to a system that uses insulin only.”

He pointed to a 2017 meta-analysis that showed improved time-in-range and greater reductions in hypoglycemia with dual- versus single-hormone systems. 

And, in unpublished data from a randomized random-order crossover study of 23 patients with type 1 diabetes who each spent a week with usual care (insulin pump with or without CGM), insulin-only iLet, and bihormonal iLet, mean glucose levels were 165, 148, and 139 mg/dL, respectively. Time-in-range was 60%, 72%, and 79%, and median time with glucose below 54 mg/dL was 0.6%, 0.6%, and 0.2%, respectively.

Dr. Russell also addressed each of the arguments made by Dr. Hovorka and others against glucagon use.

Regarding the need for a stable glucagon formulation, he said that the analogue being developed for the iLet, dasiglucagon (Zealand pharma), is stable for more than a month at 40º C, with higher bioavailability and slightly slower absorption than glucagon.

And while he acknowledged the need for two separate hormone cartridges, Dr. Russell said that the Gen4 version of the iLet is fairly simple and intuitive, and the device itself is about the same size as the Tandem t:slim.

Use of glucagon didn’t increase insulin use in iLet trials, nor was it associated with increased reported nausea or liver glycogen depletion.

And users universally reported preferring the bihormonal system.

Long-term safety of chronic glucagon exposure has yet to be addressed, but animal data are reassuring, Dr. Russell said.

Regarding increased cost, he pointed to 2018 data showing that the incremental improvement in glycemic control from no automation to single-hormone automation is the same as from single to dual (mean glucose reductions of 7.4 and 13.6 mg/dL, respectively, and decreases in time spent in hypoglycemia of 1.28% vs. 2.95%).

“I would argue that, if one can justify adding automation, one could justify some additional expense to add the cost of glucagon.” And, he said, the cost would likely be based on a negotiation around the extra value offered by the dual-hormone system.

“The addition of glucagon, I believe, will be justified by the improved outcomes and improved quality of life,” he concluded.

Some automated insulin delivery systems currently in development add glucagon and/or pramlintide to insulin, but whether the extra hormones are worth the additional cost and effort is a subject of debate.

Sara Freeman/MDedge News

Also called closed-loop or artificial pancreas systems, they are comprised of an insulin pump and a continuous glucose monitor (CGM) that communicate via a built-in algorithm to deliver insulin based on glucose levels. Currently available systems are called hybrid closed loops because they still require user input for meals, exercise, illness, and other special circumstances.

Two hybrid closed-loop systems available in the United States, the Medtronic Minimed 670G and the Tandem Control-IQ, as well as the Medtronic Minimed 780G that was just approved in Europe, use insulin only.

Of all ongoing active closed-loop clinical studies, 44 involve insulin-only systems, as of May 2020.

However, two such systems in development add a glucagon analogue to insulin in the same pump (in separate cartridges), with the aim of minimizing the risk of hypoglycemia. And four investigational systems combine insulin with pramlintide (Symlin, AstraZeneca), an amylin analogue that reduces postmeal glucose spikes. Three systems in development combine all three hormones. 

In a debate during the virtual American Diabetes Association 80th Scientific Sessions, Roman Hovorka, PhD, of the University of Cambridge (England) argued in favor of insulin-only systems on the basis of efficacy, less burden and complexity, and lower cost.

But Steven J. Russell, MD, PhD, of Massachusetts General Hospital, Boston, countered that glucagon adds safety and value to the system by allowing for more aggressive insulin dosing with lower hypoglycemia risk, benefits which he said would overcome any downsides.
 

Insulin-only systems are good enough

Teens and young adults with diabetes have cognitive deficits that vary by diabetes type and could negatively impact their medical literacy and self-care, an investigator reported at the virtual annual scientific sessions of the American Diabetes Association.

Individuals with youth-onset type 1 or 2 diabetes all performed below average on tests that measure flexible thinking and problem solving, according to the investigator, who reported an analysis including 1,380 individuals enrolled in the SEARCH for Diabetes in Youth study.

That finding suggests that diabetes diagnosed before age 20 contributes to poor fluid cognitive function, which consists of skills that facilitate goal-directed behaviors, according to investigator Allison Shapiro, MPH, PhD, of the University of Colorado at Denver, Aurora.

However, individuals with type 2 diabetes (T2D) performed even worse than those with type 1 diabetes (T1D) on the fluid cognitive function tests, even after adjustment for demographic factors and other confounders, Dr. Shapiro said in her presentation.

Further analysis revealed that individuals with T2D performed significantly worse on measures of crystallized cognition, a domain that includes skills such as vocabulary and language. That suggests the poor fluid cognitive abilities in youths with diabetes may in fact be a result of poor crystallized cognitive development, according to the investigator.

“Among adolescents and young adults with youth-onset type 2 diabetes specifically, intervention should focus on developing both fluid cognitive skills and crystallized cognitive skills,” Dr. Shapiro said.

Deficits in fluid cognitive function (such as reasoning or processing speed) can negatively affect diabetes self-care, thereby potentially increasing the risk of diabetes-related complications, while deficits in crystallized cognitive function (such as vocabulary and understanding of language) could impact medical literacy further compounding the self-care issues.

The study is believed to be one of the first to compare cognitive function deficits in youths with type 1 or 2 diabetes. Although studies in adults clearly show a detrimental relationship between diabetes and cognitive function, according to Dr. Shapiro, the bulk of the research in youths has focused on T1D.

“While limited work has been done in youth-onset type 2 diabetes, cognitive deficits are consistently observed, compared to youth without diabetes,” she said.

Results of this study emphasize the importance of dietary changes and other lifestyle interventions in young patients with diabetes, according to David Della-Morte, MD, PhD, associate professor of neurology at the University of Miami.

“Even the youngest patients may develop cognitive dysfunction,” Dr. Della-Morte said in an interview. “That means that lifestyle is very important, especially in obese patients that are prone to develop type 2 diabetes.”

The analysis by Dr. Shapiro and coinvestigators included 1,095 youths and young adults with T1D and 285 with T2D who had undergone a cognition assessment as part of a study visit. They were aged an average of 22 years, and had an average diabetes duration of 11 years.

The overall fluid cognition score was significantly lower in those individuals with T2D, compared with those with T1D, investigators found. Compared with the national average score of 100, the T2D group scored 84.7, or a full standard deviation below that average, said Dr. Shapiro, while those with T1D scored 95.5 (P < .001).

Participants with T2D also scored significantly lower in individual measures of fluid cognition, including processing speed, inhibitory control and attention, working memory, and episodic memory, she reported. At first glance, that suggested youth-onset T2D has a specific effect on fluid cognition; however, the story remains incomplete without looking at crystallized cognition markers such as vocabulary and language.

Toward that end, a picture vocabulary test conducted as part of the cognitive assessment showed a significant difference between those with T2D, who on average scored 91.5, and those with T1D, who scored 103.6 (P < .001). Accounting for those picture vocabulary scores attenuated the differences between groups in fluid cognitive scores, suggesting that differences in crystallized cognitive function underly the observed differences in fluid cognitive function between groups, Dr. Shapiro said.

Skills such as vocabulary and language are thought to be stable and not influenced by neurologic changes brought on by disease processes such as youth-onset diabetes, but rather, influenced by factors such as childcare and education, according to Dr. Shapiro.

“Crystallized cognition therefore provides a window into an individual’s cognitive functioning, independent of their disease or premorbid to the onset of their disease,” she said.

Dr. Shapiro said she had no conflicts of interest to disclose.

Although studies in adults clearly show a detrimental relationship between diabetes and cognitive function, according to Dr. Shapiro, the bulk of the research in youths has focused on T1D.

“While limited work has been done in youth-onset type 2 diabetes, cognitive deficits are consistently observed, compared to youth without diabetes,” she said.

Results of this study emphasize the importance of dietary changes and other lifestyle interventions in young patients with diabetes, according to David Della-Morte, MD, PhD, associate professor of neurology at the University of Miami.

“Even the youngest patients may develop cognitive dysfunction,” Dr. Della-Morte said in an interview. “That means that lifestyle is very important, especially in obese patients that are prone to develop type 2 diabetes.”

The analysis by Dr. Shapiro and coinvestigators included 1,095 youths and young adults with T1D and 285 with T2D who had undergone a cognition assessment as part of a study visit. They were aged an average of 22 years, and had an average diabetes duration of 11 years.

The overall fluid cognition score was significantly lower in those individuals with T2D, compared with those with T1D, investigators found. Compared with the national average score of 100, the T2D group scored 84.7, or a full standard deviation below that average, said Dr. Shapiro, while those with T1D scored 95.5 (P < .001).

Participants with T2D also scored significantly lower in individual measures of fluid cognition, including processing speed, inhibitory control and attention, working memory, and episodic memory, she reported. At first glance, that suggested youth-onset T2D has a specific effect on fluid cognition; however, the story remains incomplete without looking at crystallized cognition markers such as vocabulary and language.

Toward that end, a picture vocabulary test conducted as part of the cognitive assessment showed a significant difference between those with T2D, who on average scored 91.5, and those with T1D, who scored 103.6 (P < .001). Accounting for those picture vocabulary scores attenuated the differences between groups in fluid cognitive scores, suggesting that differences in crystallized cognitive function underly the observed differences in fluid cognitive function between groups, Dr. Shapiro said.

Skills such as vocabulary and language are thought to be stable and not influenced by neurologic changes brought on by disease processes such as youth-onset diabetes, but rather, influenced by factors such as childcare and education, according to Dr. Shapiro.

“Crystallized cognition therefore provides a window into an individual’s cognitive functioning, independent of their disease or premorbid to the onset of their disease,” she said.

Dr. Shapiro said she had no conflicts of interest to disclose.

Glycemic control among youth with diabetes is no better today than it was in 2002 and in some subgroups it’s worse, despite increased availability of diabetes technology, newer therapies, and more aggressive recommended blood glucose targets, new research finds.

The sobering data from 6,399 participants in the longitudinal SEARCH for Diabetes in Youth study were presented June 15 at the virtual American Diabetes Association 80th Scientific Sessions by Faisal S. Malik, MD, of the University of Washington, Seattle, and Seattle Children’s Research Institute.

“Our finding that current youth and young adults with diabetes are not demonstrating improved glycemic control, compared to earlier cohorts in the SEARCH study was surprising given how the landscape of diabetes management has changed dramatically over the past decade,” Dr. Malik said in an interview.
 

Urgent need to improve glycemic control in youth with diabetes

The SEARCH study, funded by the National Institute of Diabetes and Digestive and Kidney Diseases and the Centers for Disease Control and Prevention, is the largest and most diverse study of diabetes in youth in the United States. It has over 27,000 participants seen at five study sites in California, Colorado, Ohio, South Carolina, and Washington state.

Among youth with type 1 diabetes in the study, average hemoglobin A1c rose from 8.6% in 2002-2007 (n = 3,451) to 8.8% in 2008-2014 (n = 2,254), and remained at 8.8% in 2014-2019 (n = 1,651).

Among those with type 2 diabetes, A1c levels fluctuated from 8.8% (n = 379) to 8.4% (n = 327) to 8.5% (n = 469) in the three time periods, respectively.

By contrast, in 2014 the ADA recommended an A1c of less than 7.5% for youth of all ages with type 1 diabetes, down from prior less stringent targets.

In 2018, the ADA advised A1c levels below 7% for youth with type 2 diabetes. In both cases, targets may be adjusted based on individual circumstances.

A particularly striking data point was seen among youth who had type 2 diabetes for 10 years or more: average A1c skyrocketed from 7.9% in 2008-2013 to 10.1% in 2014-2019. The numbers were small, 25 patients in the earlier cohort and 149 patients in the later, yet the difference was still significant (P < .01). And in those with type 1 diabetes for 5-9 years, average A1c rose from 8.7% in 2002-2007 (n = 769) to 9.2% in 2014-2019 (n = 654) (P < .01).

“These results suggest that not all youth with diabetes are directly benefiting from the increased availability of diabetes technology, newer therapies, and the use of more aggressive glycemic targets for youth with diabetes over time,” Dr. Malik said.

“Recognizing that lower A1c levels in adolescence and young adulthood is associated with lower risk and rate of microvascular and macrovascular complications, this study further underscores the urgent need for effective treatment strategies to improve glycemic control in youth and young adults with diabetes,” he added.

Asked to comment, David M. Maahs, MD, said in an interview that the type 1 diabetes data are “very consistent” with those found in the T1D Exchange registry study but that both datasets include patients seen at diabetes centers and therefore may not represent the entire population.

“I don’t think there’s reason to think we’re actually doing any better than these data indicate,” said Dr. Maahs, professor of pediatrics and division chief of pediatric endocrinology at Stanford (Calif.) University.

Other countries improving, U.S. getting worse

Dr. Maahs contrasted the U.S. situation with that of the English/Welsh National Paediatric Diabetes Audit and some European countries that have improved pediatric diabetes control and outcomes using a population-based approach.

“In the United States we have a disjointed irrational health care system that doesn’t invest in diabetes education and in the basic care and monitoring that children with diabetes need to get better glucose control,” he said.

“We’re not having systematic approaches to it as many European countries have. They have gotten better results over this same time period. In the United States we’re getting worse,” Dr. Maahs observed.

And as far as diabetes technology is concerned, Dr. Maahs said, “there’s more to it than just throwing technology at it. People who are using technology are getting better outcomes, but there are a lot of people who don’t get access to it.”

Indeed, Dr. Malik pointed out, “while the recent SEARCH [type 1 diabetes] cohorts had increased insulin pump use, it’s worth noting that more than half of the participants in the most recent cohort were not using diabetes technology.” And even “fewer participants were likely using continuous glucose monitors during our study period.”
 

Barriers to care, type 1 diabetes is “very labor intensive”

Dr. Malik said that barriers to care include “high cost, alarm fatigue, and encumbrances of wearing a mechanical device [that] continue to present challenges around technology use,” as well as “inequities in the use of these technologies across socioeconomic status, health insurance, and race/ethnicity, which need to be addressed.”

Dr. Maahs did have a recommendation for U.S. primary care physicians who are managing youth with either type of diabetes: a tele-education program called Project ECHO (Extension for Community Healthcare Outcomes), which uses a train-the-trainer model, rather than direct telehealth, to bring tele-education to primary care providers.

Such programs in diabetes have shown some success, he said.

Type 1 diabetes, Dr. Malik noted, “is very labor intensive. Frequent or constant monitoring of glucose and multiple daily doses of basal and bolus insulin are commonly recommended by type 1 diabetes care providers in the United States.”

“This has led to increasingly burdensome management for children and their caregivers, which often results in suboptimal adherence, suboptimal glycemic control, and greater risk of complications.”

Dr. Malik encourages providers “to engage in person-centered collaborative care as recommended by the ADA, which is guided by shared decision-making in treatment regimen selection, facilitation of obtaining needed medical and psychosocial resources, and shared monitoring of agreed-upon regimen and lifestyle.”

Dr. Malik has reported no relevant financial relationships. Dr. Maahs has reported being on advisory boards for Medtronic, Lilly, and Abbott.

The recent resurgence in diabetes-related lower-extremity amputations in the United States is not limited to younger adults, according to the author of a recent study that documents similar increases among an older population of Medicare beneficiaries.

While the rate of amputations fell among these older adults from 2000 to 2009, it increased significantly from 2009 to 2017, albeit at a “less severe rate” than recently reported in younger populations, said study investigator Jessica Harding, PhD.

The rate of nontraumatic lower extremity amputation (NLEA) was ticking upward by more than 1% per year over the 2009-2017 period, according to Dr. Harding, assistant professor in the department of surgery at Emory University, Atlanta.

This latest report follows one from last year, published in Diabetes Care, that documented an annual percentage increase approaching 6% between 2009 and 2015, driven by larger increases among adults 18-64 years of age, as well as an increase among men.

It’s not clear why rates of NLEA would be on the rise among younger and older adults in the United States, Dr. Harding said, though factors she said could be implicated include changes in amputation practice, increased comorbidities, higher insulin costs, or shortcomings in early prevention programs.

“We need large-scale studies with granular data to tease out key risk factors that could help identify the drivers of these increases in amputations,” Dr. Harding said in a presentation at the virtual annual scientific sessions of the American Diabetes Association.

“In the interim, increased attention to preventive foot care across the age spectrum could benefit adults with diabetes,” she added.

Devastating complication in older adults

The latest findings from Dr. Harding and coauthors emphasize the importance of a “team approach” to early prevention in older adults with diabetes, said Derek LeRoith, MD, PhD, director of research in the division of endocrinology, diabetes, and bone diseases with Icahn School of Medicine at Mount Sinai, New York.

“If you take a 75-year-old or even an 80-year-old, their life expectancy can still be a good 10 years or more,” Dr. LeRoith said in an interview. “We shouldn’t give up on them – we should be treating them to prevent complications.”

Lower-extremity amputation is a “particularly devastating” complication that can compromise mobility, ability to exercise, and motivation, according to Dr. LeRoith, lead author of a recent Endocrine Society clinical practice guideline that urges referral of older adults with diabetes to a podiatrist, orthopedist, or vascular specialist for preventive care.

“Quite often, treating their glucose or high blood pressure will be much more difficult because of these changes,” he said.
 

Lower extremity amputation trends upward

Rates of NLEA declined for years, only to rebound by 50%, according to authors of a recent analysis of Nationwide Inpatient Sample (NIS) data reported last year. In their report, the age-standardized diabetes-related NLEA rate per 1,000 adults with diabetes went from 5.30 in 2000, down to 3.07 in 2009/2010, and back up to 4.62 by 2015 (Diabetes Care. 2019 Jan;42:50-4).

The resurgence was fueled mainly by an increased rate of amputations in younger and middle-aged adults and men, and through increases in minor amputations, notably the toe, according to the investigators. “These changes in trend are concerning because of the disabling and costly consequences of NLEAs as well as what they may mean for the direction of efforts to reduce diabetes-related complications,” authors of that report said at the time.

In the current study, Dr. Harding and colleagues included Medicare Parts A and B claims data for beneficiaries enrolled from 2000 to 2017. There were 4.6 million Medicare fee-for-service beneficiaries with diabetes in 2000, increasing to 6.9 million in 2017, she reported at the virtual ADA meeting.

Rates of NLEA followed a trajectory similar to what was seen in the earlier NIS report, falling from 8.5 per 1,000 persons in 2000 to 4.4 in 2009, for an annual percentage change of –7.9 (P < .001), Dr. Harding said. Then rates ticked upward again, to 4.8 in 2017, for an annual percentage change of 1.2 over that later period (P < .001).

While the trend was similar for most subgroups analyzed, the absolute rates were highest among men and black individuals in this older patient population, reported Dr. Harding and coauthors.

Dr. Harding said she and coauthors had no disclosures related to the research, which was performed as a collaboration between Emory University and the Centers for Disease Control and Prevention Division of Diabetes Translation.

Lower-extremity amputation is a “particularly devastating” complication that can compromise mobility, ability to exercise, and motivation, according to Dr. LeRoith, lead author of a recent Endocrine Society clinical practice guideline that urges referral of older adults with diabetes to a podiatrist, orthopedist, or vascular specialist for preventive care.

“Quite often, treating their glucose or high blood pressure will be much more difficult because of these changes,” he said.
 

Lower extremity amputation trends upward

Rates of NLEA declined for years, only to rebound by 50%, according to authors of a recent analysis of Nationwide Inpatient Sample (NIS) data reported last year. In their report, the age-standardized diabetes-related NLEA rate per 1,000 adults with diabetes went from 5.30 in 2000, down to 3.07 in 2009/2010, and back up to 4.62 by 2015 (Diabetes Care. 2019 Jan;42:50-4).

The resurgence was fueled mainly by an increased rate of amputations in younger and middle-aged adults and men, and through increases in minor amputations, notably the toe, according to the investigators. “These changes in trend are concerning because of the disabling and costly consequences of NLEAs as well as what they may mean for the direction of efforts to reduce diabetes-related complications,” authors of that report said at the time.

In the current study, Dr. Harding and colleagues included Medicare Parts A and B claims data for beneficiaries enrolled from 2000 to 2017. There were 4.6 million Medicare fee-for-service beneficiaries with diabetes in 2000, increasing to 6.9 million in 2017, she reported at the virtual ADA meeting.

Rates of NLEA followed a trajectory similar to what was seen in the earlier NIS report, falling from 8.5 per 1,000 persons in 2000 to 4.4 in 2009, for an annual percentage change of –7.9 (P < .001), Dr. Harding said. Then rates ticked upward again, to 4.8 in 2017, for an annual percentage change of 1.2 over that later period (P < .001).

While the trend was similar for most subgroups analyzed, the absolute rates were highest among men and black individuals in this older patient population, reported Dr. Harding and coauthors.

Dr. Harding said she and coauthors had no disclosures related to the research, which was performed as a collaboration between Emory University and the Centers for Disease Control and Prevention Division of Diabetes Translation.

Adults with prediabetes of normal weight may derive at least as much benefit from lifestyle health coaching programs as adults who are overweight or obese, results of a recent nonrandomized, real-world study show.

Fasting plasma glucose (FPG) normalized in about 63% of prediabetic adults with normal body mass index (BMI) participating in a personalized coaching program that emphasized exercise, nutrition, and weight management, according to researcher Mandy Salmon, MS.

By contrast, FPG normalized in about 52% of overweight and 44% of obese prediabetic individuals participating in the program, according to Ms. Salmon, a medical student at the University of Pennsylvania, Philadelphia.

The normal-weight individuals didn’t lose any weight after participating in the coaching program, but they did significantly increase exercise, as did their overweight and obese counterparts, Ms. Salmon said in a presentation of her findings at virtual annual scientific sessions of the American Diabetes Association.

That means not only that normal-weight individuals shouldn’t be excluded from coaching interventions for diabetes prevention, but also that the success of such programs shouldn’t be judged solely on the magnitude of weight loss, according to the researcher.

“It is interesting to note that, although the normal weight group lost the least amount of weight, they still benefited from the lifestyle health coaching program, but having a resultant greatest decrease in fasting plasma glucose and normalization to a range of someone without prediabetes,” Ms. Salmon said.

The fact that most of those patients experienced normalization of FPG despite no weight loss emphasizes the importance of physical activity as a lifestyle intervention, according to Mark Schutta, MD, medical director of Penn Rodebaugh Diabetes Center in Philadelphia, who was not involved in the study.

“You hear these axioms that say things like, ‘you can never outexercise a bad diet,’ and that’s probably true. But all the studies will tell us that a fit, overweight diabetic has much lower risk of cardiovascular disease than an unfit overweight diabetic,” Dr. Schutta said in an interview.
 

Benefits in normal-weight individuals

One in three Americans has prediabetes, and of those individuals, one in five have a normal BMI, Ms. Salmon said in her virtual ADA presentation.

It’s thought that diabetes may develop in those normal-weight individuals through different pathological mechanisms than in overweight or obese individuals. In turn, that could mean that standard methods for staving off diabetes prevention may not be as effective for them, she said.

Those mechanisms are not well understood; even so, normal BMI is currently an exclusion criterion for many diabetes prevention programs, she added, including the Center for Disease Control and Prevention’s National Diabetes Prevention Program, which specifically requires that individuals have an elevated BMI to be eligible for referral.

To evaluate the potential benefits of coaching in normal-weight individuals, the investigators studied a cohort of 1,897 adults with prediabetes, defined as a baseline FPG of 100-125 mg/dL, who were participating in a lifestyle health coaching program. Of those participants, 188, or about 10% had a normal BMI of 18.5-24.9 mg/m². Another 495 participants were overweight, with BMIs between 25 and 29.9, while 1,214 were obese, with a BMI of at least 30.

The intervention included an initial assessment to generate goals and a personalized action plan based on the individual’s risk factors, according to Ms. Salmon, along with an action plan that included one-on-one, behaviorally oriented, technology-enabled lifestyle health coaching focused on exercise and physical activity, weight management, and nutrition.
 

Key findings

With a mean follow-up of 145 days, weight loss in the obese group was greater than that of the overweight group, with mean BMI changes of –1.3 and –0.6, respectively, while there was no significant change in weight for the normal-weight individuals, according to Ms. Salmon.

By contrast, weekly aerobic activity increased significantly in all three groups, she added, with average increases of 95 minutes in the obese group, 98 minutes in the overweight group, and 77 minutes in the normal-weight group.

Likewise, significant decreases in FPG were seen in all 3 groups, with average changes of –6 mg/dL for the obese participants, –7 mg/dL for overweight participants, and –9 mg/dL for normal-weight participants, Ms. Salmon said.

The proportion of individuals whose FPG normalized was highest in the normal-weight group, at 62%, compared with 51.7% for overweight and 44% for obese individuals, she added.

Most previous studies of lifestyle interventions for prediabetes have excluded normal-weight individuals, according to Ms. Salmon, who said one strength of her study was that the subjects were already participating in the established lifestyle health coaching program and didn’t interact with the team of researchers.

“It was an effectiveness study in which we could see the real-world benefits of the program, rather than a theoretical efficacy study,” she said.

Ms. Salmon said she had no potential conflicts of interest to disclose. The coinvestigators of the study were members or employees of a privately held population health management company called INTERVENT International.

Treatment of patients with type 2 diabetes with the SGLT2 inhibitor dapagliflozin led to a significant drop in the occurrence of ‘fast decline’ of renal function in more than 15,000 patients enrolled in the drug’s main cardiovascular outcome trial, another example of the potent renal protective effects of agents from this drug class.

Among patients with type 2 diabetes enrolled in the DECLARE-TIMI 58 trial, the incidence of a fast decline in renal function, defined as a drop in estimated glomerular filtration rate (eGFR) of at least 3 mL/min per 1.73 m², was 27% among patients treated with dapagliflozin and 37% in control patients who received placebo, a statistically significant difference for this post-hoc analysis, Itamar Raz, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

This finding, which adds to a long list of other renal function parameters reported to have been improved by treatment with sodium-glucose cotransporter 2 (SGLT2) inhibitors, “emphasizes the value of SGLT2 inhibitors as an important component of both prevention and treatment of chronic kidney disease among patients with type 2 diabetes,” said Dr. Raz, a diabetes researcher and professor of medicine at Hadassah University Hospital in Jerusalem.

The primary, prespecified renal outcomes in DECLARE-TIMI 58 were a cardiorenal composite outcome of sustained decline of at least 40% in eGFR to less than 60 mL/min per 1.73 m², end-stage renal disease (defined as dialysis for at least 90 days, kidney transplantation, or confirmed sustained eGFR of less than 15 mL/min per 1.73 m²), or death from renal or cardiovascular causes; and a second prespecified renal-specific composite outcome that was the same except for excluding death from cardiovascular causes. The results showed that the cardiorenal outcome dropped by a statistically significant 24% with dapagliflozin treatment relative to control patients, and the renal-specific outcome fell by a statistically significant 47% with dapagliflozin relative to control patients (Lancet Diab Endocrinol. 2019 Aug 1;7[8];606-17).

The new findings on the incidence of fast decline in renal function help to further flesh out the scope of renal benefit exerted by SGLT2 inhibitors like dapagliflozin in patients with type 2 diabetes, said experts. Fast decline is a relatively recently devised measure of a high-risk, precipitous loss of renal function that has been defined as a drop of either 3 or 5 mL/min per 1.73 m² per year (Kidney Int. 2017 Jun;91[6]:1300-11); for this analysis Dr. Raz and his associates used the less stringent definition.
 

Finding and treating ‘fast decliners’

The new report from Dr. Raz “confirms the original [renal] findings and looks to expand them to a particularly high risk group: the fast decliners,” commented Robert A. Gabbay, MD, chief science & medical officer of the ADA. “In some ways, the group of patients that we need to find a better treatment for most are those whose GFR declines quickly. We don’t always know who they are until after the fact, and studies have been looking for markers that might prospectively identify them,” he said in an interview.

The new analysis showed that dapagliflozin “was effective in this subgroup of patients. Furthermore, it didn’t matter if they had significant baseline disease or not. Even people with normal kidney function [at baseline] who were still fast decliners fared better with the drug than without it. This suggests that, if it can be confirmed in a prospective study, dapagliflozin might be effective very early in the course of treatment if we can identify who will be the fast decliners.”

Dr. Raz and his associates had the data necessary to calculate the rates of eGFR decline during the full follow-up period for 15,012 of the 17,160 patients enrolled in DECLARE-TIMI 58, and they found that 4,788 (32%) were fast decliners and 10,224 had a slower rate of renal deterioration. The average annual decline in eGFR during the period from 6 months after study entry through 4 years was 6.3 mL/min per 1.73 m² per year (median of 5.1 mL/min per 1.73 m² per year) among the fast decliners, and zero (median of 0.6 mL/min per 1.73 m² per year) among the other patients.
 

Overcoming dapagliflozin’s initial eGFR reduction

The researchers focused on the 6-month to 4-year period of treatment as more representative of the impact of dapagliflozin because the SGLT2 inhibitors have an established pattern of triggering an initial, moderate decline in eGFR over roughly the first 6 months on the drug, which is similar to what happens to patients who start treatment with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker.

“Some patients get as much as a 10% decline in eGFR” when SGLT2 inhibitor treatment starts, but “patients do better over time even with this initial hit,” the same way they do on drugs that act on the renin-angiotensin system, explained Silvio E. Inzucchi, MD, an endocrinologist and professor of medicine at Yale University in New Haven who has extensively studied the SGLT2 inhibitors.

The analyses reported by Dr. Raz showed that the protection against fast decline during the 6-month to 4-year period with dapagliflozin treatment was consistent across a range of patient subgroups regardless of age, duration of their type 2 diabetes, their baseline level of hyperglycemia, and their baseline eGFR. Nearly half the patients enrolled in DECLARE-TIMI 58 had an eGFR at baseline of at least 91 mL/min per 1.73 m² and in this subgroup the incidence of fast decliners was 23% with dapagliflozin and 31% on placebo. Among the 45% of patients who began with an eGFR of 60-90 mL/min per 1.73 m² the fast-decliner incidence was 32% and 43% when on or off dapagliflozin. Among the 7% of patients who entered with an eGFR below 60 mL/min per 1.73 m², the fast-decliner incidence was 25% on dapagliflozin and 36% among controls. All the between-group differences were statistically significant.

The incidence of fast decliners was also lower with dapagliflozin treatment when the analysis included the entire first 4 years on treatment, including the first 6 months when SGLT2s usually spikes a loss of renal function. For the entire 4-year period, fast decline occurred among 34% of patients on dapagliflozin and in 37% of control patients, a statistically significant difference.

The mechanisms behind the consistent renal-protective effects of the SGLT2 inhibitors remain unclear right now, but likely seem related to the “perfect” diuretic action the drugs produce, said Dr. Inzucchi. “They’re not as hugely effective as diuretics, but they’re gentler.” While the SGLT2 inhibitors cause a modest amount of fluid loss ”for some reason they don’t activate the compensatory mechanisms that prevent further reductions in plasma volume,” a property that manifests as little or no change in catecholamines or renin-angiotensin activity, which sets this diuretic action apart from what happens with conventional diuretic drugs, he said in an interview.

In DECLARE-TIMI 58 treatment with dapagliflozin met its primary safety outcome of noninferiority to placebo with respect to major adverse cardiovascular events. The results failed to show statistically significant superiority for one of the primary efficacy endpoints, the rate of major adverse coronary events, but they did show significantly better performance for the second primary efficacy outcome of the rate of cardiovascular death or hospitalization for heart failure, which occurred in 4.9% of patients treated with dapagliflozin and in 5.8% of the control patients during a median follow-up of 4.2 years (N Engl J Med. 2019 Jan 24;380[4]:347-57).

DECLARE-TIMI 58 was sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Raz has been an advisor to and speaker on behalf of AstraZeneca as well as several other companies. Dr. Gabbay had no relevant disclosures. Dr. Inzucchi has been a consultant to AstraZeneca, and also to Abbott, Boehringer Ingelheim, Merck, Novo Nordisk, Sanofi/Lexicon, and vTv Therapeutics.

The results failed to show statistically significant superiority for one of the primary efficacy endpoints, the rate of major adverse coronary events, but they did show significantly better performance for the second primary efficacy outcome of the rate of cardiovascular death or hospitalization for heart failure, which occurred in 4.9% of patients treated with dapagliflozin and in 5.8% of the control patients during a median follow-up of 4.2 years (N Engl J Med. 2019 Jan 24;380[4]:347-57).

Treatment of patients with type 2 diabetes with the SGLT2 inhibitor dapagliflozin led to a significant drop in the occurrence of ‘fast decline’ of renal function in more than 15,000 patients enrolled in the drug’s main cardiovascular outcome trial, another example of the potent renal protective effects of agents from this drug class.

Among patients with type 2 diabetes enrolled in the DECLARE-TIMI 58 trial, the incidence of a fast decline in renal function, defined as a drop in estimated glomerular filtration rate (eGFR) of at least 3 mL/min per 1.73 m², was 27% among patients treated with dapagliflozin and 37% in control patients who received placebo, a statistically significant difference for this post-hoc analysis, Itamar Raz, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

This finding, which adds to a long list of other renal function parameters reported to have been improved by treatment with sodium-glucose cotransporter 2 (SGLT2) inhibitors, “emphasizes the value of SGLT2 inhibitors as an important component of both prevention and treatment of chronic kidney disease among patients with type 2 diabetes,” said Dr. Raz, a diabetes researcher and professor of medicine at Hadassah University Hospital in Jerusalem.

The primary, prespecified renal outcomes in DECLARE-TIMI 58 were a cardiorenal composite outcome of sustained decline of at least 40% in eGFR to less than 60 mL/min per 1.73 m², end-stage renal disease (defined as dialysis for at least 90 days, kidney transplantation, or confirmed sustained eGFR of less than 15 mL/min per 1.73 m²), or death from renal or cardiovascular causes; and a second prespecified renal-specific composite outcome that was the same except for excluding death from cardiovascular causes. The results showed that the cardiorenal outcome dropped by a statistically significant 24% with dapagliflozin treatment relative to control patients, and the renal-specific outcome fell by a statistically significant 47% with dapagliflozin relative to control patients (Lancet Diab Endocrinol. 2019 Aug 1;7[8];606-17).

The new findings on the incidence of fast decline in renal function help to further flesh out the scope of renal benefit exerted by SGLT2 inhibitors like dapagliflozin in patients with type 2 diabetes, said experts. Fast decline is a relatively recently devised measure of a high-risk, precipitous loss of renal function that has been defined as a drop of either 3 or 5 mL/min per 1.73 m² per year (Kidney Int. 2017 Jun;91[6]:1300-11); for this analysis Dr. Raz and his associates used the less stringent definition.
 

Finding and treating ‘fast decliners’

The new report from Dr. Raz “confirms the original [renal] findings and looks to expand them to a particularly high risk group: the fast decliners,” commented Robert A. Gabbay, MD, chief science & medical officer of the ADA. “In some ways, the group of patients that we need to find a better treatment for most are those whose GFR declines quickly. We don’t always know who they are until after the fact, and studies have been looking for markers that might prospectively identify them,” he said in an interview.

The new analysis showed that dapagliflozin “was effective in this subgroup of patients. Furthermore, it didn’t matter if they had significant baseline disease or not. Even people with normal kidney function [at baseline] who were still fast decliners fared better with the drug than without it. This suggests that, if it can be confirmed in a prospective study, dapagliflozin might be effective very early in the course of treatment if we can identify who will be the fast decliners.”

Dr. Raz and his associates had the data necessary to calculate the rates of eGFR decline during the full follow-up period for 15,012 of the 17,160 patients enrolled in DECLARE-TIMI 58, and they found that 4,788 (32%) were fast decliners and 10,224 had a slower rate of renal deterioration. The average annual decline in eGFR during the period from 6 months after study entry through 4 years was 6.3 mL/min per 1.73 m² per year (median of 5.1 mL/min per 1.73 m² per year) among the fast decliners, and zero (median of 0.6 mL/min per 1.73 m² per year) among the other patients.
 

Overcoming dapagliflozin’s initial eGFR reduction

The researchers focused on the 6-month to 4-year period of treatment as more representative of the impact of dapagliflozin because the SGLT2 inhibitors have an established pattern of triggering an initial, moderate decline in eGFR over roughly the first 6 months on the drug, which is similar to what happens to patients who start treatment with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker.

“Some patients get as much as a 10% decline in eGFR” when SGLT2 inhibitor treatment starts, but “patients do better over time even with this initial hit,” the same way they do on drugs that act on the renin-angiotensin system, explained Silvio E. Inzucchi, MD, an endocrinologist and professor of medicine at Yale University in New Haven who has extensively studied the SGLT2 inhibitors.

The analyses reported by Dr. Raz showed that the protection against fast decline during the 6-month to 4-year period with dapagliflozin treatment was consistent across a range of patient subgroups regardless of age, duration of their type 2 diabetes, their baseline level of hyperglycemia, and their baseline eGFR. Nearly half the patients enrolled in DECLARE-TIMI 58 had an eGFR at baseline of at least 91 mL/min per 1.73 m² and in this subgroup the incidence of fast decliners was 23% with dapagliflozin and 31% on placebo. Among the 45% of patients who began with an eGFR of 60-90 mL/min per 1.73 m² the fast-decliner incidence was 32% and 43% when on or off dapagliflozin. Among the 7% of patients who entered with an eGFR below 60 mL/min per 1.73 m², the fast-decliner incidence was 25% on dapagliflozin and 36% among controls. All the between-group differences were statistically significant.

The incidence of fast decliners was also lower with dapagliflozin treatment when the analysis included the entire first 4 years on treatment, including the first 6 months when SGLT2s usually spikes a loss of renal function. For the entire 4-year period, fast decline occurred among 34% of patients on dapagliflozin and in 37% of control patients, a statistically significant difference.

The mechanisms behind the consistent renal-protective effects of the SGLT2 inhibitors remain unclear right now, but likely seem related to the “perfect” diuretic action the drugs produce, said Dr. Inzucchi. “They’re not as hugely effective as diuretics, but they’re gentler.” While the SGLT2 inhibitors cause a modest amount of fluid loss ”for some reason they don’t activate the compensatory mechanisms that prevent further reductions in plasma volume,” a property that manifests as little or no change in catecholamines or renin-angiotensin activity, which sets this diuretic action apart from what happens with conventional diuretic drugs, he said in an interview.

The results failed to show statistically significant superiority for one of the primary efficacy endpoints, the rate of major adverse coronary events, but they did show significantly better performance for the second primary efficacy outcome of the rate of cardiovascular death or hospitalization for heart failure, which occurred in 4.9% of patients treated with dapagliflozin and in 5.8% of the control patients during a median follow-up of 4.2 years (N Engl J Med. 2019 Jan 24;380[4]:347-57).

The cardiovascular outcome trial results for a fourth sodium-glucose cotransporter 2 (SGLT2) inhibitor, ertugliflozin, were most notable for their consistency with the four prior, similar trials run on the three other drugs from this class on the U.S. market, canagliflozin, dapagliflozin, and empagliflozin, further solidifying the important role this drug class has recently taken on for patients with type 2 diabetes.

But the ertugliflozin results, which showed statistically significant superiority to placebo for just one endpoint, hospitalization for heart failure, made it unclear whether clinicians will regard ertugliflozin as the top agent from this class to prescribe.

“Our big takeaway is that the findings are consistent with what’s been seen in the other studies” of cardiovascular and renal outcomes in the EMPA-REG OUTCOME study of empagliflozin (N Engl J Med. 2015 Nov 26;373[22]:2117-28 ), the CANVAS (N Engl J Med. 2017 Aug 17;377[7]:644-57) and CREDENCE (N Engl J Med. 2019 June 13;380[24]:2295-306 ) studies of canagliflozin, and the DECLARE-TIMI 58 trial with dapagliflozin (N Engl J Med. 2019 Jan 24;380[4]:347-57), Christopher P. Cannon, MD, said at the virtual annual scientific sessions of the American Diabetes Association.

The cardiovascular outcome trials (CVOTs), mandated in 2008 by Food and Drug Administration guidance for type 2 diabetes drugs that is now in the process of undergoing an update, have had the main goal of proving safety, and the primary endpoint of the new ertugliflozin trial, VERTIS-CV, was noninferiority to placebo when used on top of standard type 2 diabetes medications for the combined endpoint of cardiovascular death, nonfatal MI, or nonfatal stroke.
 

Key findings

Both of the tested dosages of ertugliflozin, 5 mg and 15 mg daily, met this endpoint, with event rates over a median 3.0 years of follow-up that ran very close to the placebo rate, clearly proving noninferiority. But the results showed no suggestion of superiority in a study that randomized 5,499 patients to either of the ertugliflozin regimens and 2,747 to placebo, reported Dr. Cannon, a cardiologist and professor of medicine at Harvard Medical School, Boston.

The primary outcome also showed similar event rates for each component of the composite endpoint, and subgroup analysis showed consistent results from ertugliflozin, compared with placebo, regardless of study-cohort subdivision by demographic, clinical, or treatment factors.

The trial design called for a hierarchical sequence of secondary-outcome superiority analyses, starting with the impact of ertugliflozin on cardiovascular death or heart failure hospitalization, and for this outcome ertugliflozin showed a point estimate of a 12% relative risk reduction, compared with placebo-treated patients, but this difference was not statistically significant. This meant that all subsequent superiority analyses in this trial could only be hypothesis generating and not definitive.

This negated the statistical validity of the only statistically significant treatment difference between ertugliflozin and placebo seen in VERTIS-CV, for the outcome of hospitalization for heart failure, where ertugliflozin treatment cut this outcome by 30%, compared with placebo patients. The rate of cardiovascular death alone, as well as a renal composite endpoint each showed no statistically significant benefit of ertugliflozin, compared with placebo, although the renal endpoint came close, with ertugliflozin reducing the combined rate of renal death, need for dialysis, need for renal transplant, or a doubling of serum creatinine from baseline by 19%, compared with placebo (P = .08).

How results compare with prior CVOTs

In some ways, these results seemed to contrast with outcomes from the CVOTs for the other SGLT2 inhibitors, which all showed at least two statistically significant benefits for major endpoints when compared with placebo.

As summarized in a new meta-analysis of all the CVOTs by Darren K. McGuire, MD, a cardiologist and professor of medicine at the University of Texas, Dallas, both empagliflozin and canagliflozin showed statistically significant superiority compared with placebo for their trial’s primary, combined major cardiovascular adverse event endpoint, but dapagliflozin and ertugliflozin did not. Empagliflozin was the sole SGLT2 inhibitor to show a statistically significant cut in cardiovascular deaths, compared with placebo.

The primary, composite renal efficacy endpoints used in these trials were hardest to compare because they differed from study to study, but unlike ertugliflozin, all the other three drugs in the class showed a statistically significant improvement, compared with placebo, for their respective renal outcomes. On the other hand, the pattern of estimated glomerular filtration rates measured at multiple times during the various trials showed a high level of consistency across the CVOTs.

The greatest consistently among the major endpoints across the trials was for heart failure hospitalization. All four agents showed statistically significant improvements, compared with placebo, and all four had roughly equal magnitudes of effect, a cut in event rates by about one-third.

“The greatest magnitude of benefit is for reductions in heart failure hospitalizations and for renal outcomes,” with the heart failure outcomes the “most consistent” across the studies and the renal outcomes “largely consistent,” concluded Dr. McGuire. All together, the five CVOTs for these four SGLT2 inhibitors involved more than 46,000 patients.

“A lot of data suggest these are all class effects,” that are roughly similar across all four of these SGLT2 inhibitors, commented Mark E. Cooper, MBBS, a professor and head of the department of diabetes at Monash University, Melbourne, and designated discussant for the study.

There was “clear homogeneity” between the VERTIS-CV results for hospitalization for heart failure and the other CVOTs, he noted. “I think there is a difference” in the cardiovascular death outcomes, specifically the sole statistically significant, 38% relative risk reduction with empagliflozin that stood out from the other CVOTs, but this difference is “totally unexplained,” added Dr. Cooper. “To really determine differences you’d need head-to-head studies that are unlikely to happen.”

The results of new SGLT2 inhibitor meta-analysis appeared to also “support contemporary society recommendations to prioritize the use of SGLT2 inhibitors independent of glucose-control considerations in patients with type 2 diabetes with or at high risk for cardiovascular and renal complications,” said Dr. McGuire.

“The guidelines have it right. Now it’s on us to implement these treatments to appropriate patients,” concluded Dr. Cannon.
 

Study details

VERTIS-CV (Cardiovascular Outcomes Following Ertugliflozin Treatment in Type 2 Diabetes Mellitus Participants With Vascular Disease) enrolled and followed patients with type 2 diabetes and established atherosclerotic cardiovascular disease at 531 centers in 34 countries during December 2013–December 2019. Other effects from ertugliflozin recorded during the trial were consistent with prior studies of the drug, which is already FDA approved for glycemic control: Compared with placebo, ertugliflozin treatment reduced hemoglobin A1c by an average of 0.5% after 1 year, cut average body weight by about 2.5 kg after 1 year with additional modest weight loss, during subsequent years on the drug, and reduced systolic blood pressure by about 3 mm Hg after 1 year.

The drug’s safety profile was generally reassuring and consistent with prior studies of this drug and others in the class, with overall no increase in total adverse events or serious adverse events, compared with placebo, and modestly increased rates of urinary tract and mycotic genital infections.

VERTIS-CV was sponsored by Merck and Pfizer, the companies that market ertugliflozin (Steglatro). Dr. Cannon has received research funding and fees from Merck and Pfizer and from several other companies. Dr. McGuire has received honoraria from Merck, has been a consultant to Pfizer, and has had similar relationships with several other companies.

Frequent hypoglycemic episodes were linked to a raised incidence of cardiovascular events in adults with type 2 diabetes in a recent retrospective study, suggesting certain hypoglycemia-associated diabetes drugs should be avoided, an investigator said.

Patients who had more than five hypoglycemic episodes per year had a 61% greater risk of cardiovascular (CV) events, compared with patients with less frequent episodes, according to results of the study.

Although there were fewer strokes among younger patients, the overall increase in cardiovascular event risk held up regardless of age group, according to investigator Aman Rajpal, MD, of Louis Stokes Veterans Affairs Medical Center and Case Western Reserve University, both in Cleveland.

On the basis of these and earlier studies tying hypoglycemia to CV risk, health care providers need to “pay close attention” to low blood sugar and personalize glycemic control targets for each patient based on risk of hypoglycemia, Dr. Rajpal said in a presentation of the study at the virtual annual scientific sessions of the American Diabetes Association.

“Also, this suggests that avoidance of drugs associated with increased risk of hypoglycemia – namely insulin, sulfonylureas, or others – is essential to avoid and minimize the risk of cardiovascular events in this patient population with type 2 diabetes,” said Dr. Rajpal. “Let us remember part of our Hippocratic oath: ‘Above all, do no harm.’ ”
 

Tailoring treatment to mitigate risk

Mark Schutta, MD, medical director of Penn Rodebaugh Diabetes Center in Philadelphia, said that results of this study suggest a need to carefully select medical therapy for each individual patient with diabetes in order to mitigate CV risk.

“It’s really about tailoring their drugs to their personal situation,” Dr. Schutta said in an interview.

Although newer diabetes drug classes are associated with low to no risk of hypoglycemia, Dr. Schutta said that there is still a place for drugs such as sulfonylureas in certain situations.

Among sulfonylureas, glyburide comes with a much higher incidence of hypoglycemia, compared with glipizide and glimepiride, according to Dr. Schutta. “I think there’s a role for both drugs, but you have to be very careful, and you have to get the data from your patients.”
 

Hypoglycemia frequency and outcomes

Speculation that hypoglycemia could be linked to adverse CV outcomes was sparked years ago by trials such as ADVANCE. Severe hypoglycemia in that study was associated with a 168% increased risk of death from a CV cause (N Engl J Med. 2010 Oct 7;363:1410-8).

At the time, ADVANCE investigators said they were unable to find evidence that multiple severe hypoglycemia episodes conferred a greater risk of CV events versus a single hypoglycemia episode, though they added that few patients had recurrent events.

“In other words, the association between the number of hypoglycemia events, and adverse CV outcomes is still unclear,” said Dr. Rajpal in his virtual ADA presentation.
 

Potential elevated risks with more than five episodes

To evaluate the association between frequent hypoglycemic episodes (i.e., more than five per year, compared with one to five episodes) and CV events, Dr. Rajpal and colleagues evaluated outcomes data for 4.9 million adults with type 2 diabetes found in a large commercial database including information on patients in 27 U.S. health care networks.

Database records indicated that about 182,000 patients, or nearly 4%, had episodes of hyperglycemia, which Dr. Rajpal said was presumed to mean a plasma glucose level of less than 70 mg/dL.

Characteristics of the patients with more than five hypoglycemic episodes were similar to those with one to five episodes, although they were more likely to be 65 years or older, and were “slightly more likely” to be on insulin, which could possibly precipitate more hypoglycemic episodes in that group, Dr. Rajpal said.
 

Key findings

In the main analysis, Dr. Rajpal said, risk of CV events was significantly increased in those with more than five hypoglycemic episodes, compared with those with one to five episodes, with an odds ratio of 1.61 (95% confidence interval, 1.56-1.66). The incidence of cardiovascular events was 33.1% in those with more than five episodes and 23.5% in those with one to five episodes, according to the data presented.

Risks were also significantly increased specifically for cardiac arrhythmias, cerebrovascular accidents, and MI, Dr. Rajpal said, with ORs of 1.65 (95% CI, 1.9-1.71), 1.38 (95% CI, 1.22-1.56), and 1.43 (95% CI, 1.36-1.50), respectively.

Because individuals in the group with more than five hypoglycemic episodes were more likely to be elderly, Dr. Rajpal said that he and coinvestigators decided to perform an age-specific stratified analysis.

Although cerebral vascular incidence was low in younger patients, risk of CV events overall was nevertheless significantly elevated for those aged 65 years or older, 45-64 years, and 18-44 years, with ORs of 1.69 (95% CI, 1.61-1.7), 1.58 (95% CI, 1.48-1.69), and 1.62 (95% CI, 1.33-1.97).

“The results were still valid in stratified analysis based on different age groups,” Dr. Rajpal said.

Dr. Rajpal and coauthors reported that he had no conflicts of interest related to the research.
