– An investigational allogeneic stem cell–derived pancreatic islet cell replacement therapy (VX-880, Vertex Pharmaceuticals) continues to show promise as a treatment for type 1 diabetes, according to the latest data, from six patients thus far.

Two of the six are insulin-independent beyond 1 year after receiving the VX-880 infusions, and three others who received them more recently are on a similar trajectory. One dropped out because of reasons unrelated to the therapy. The remaining five are continuing to receive immunosuppressive treatment to prevent rejection of the islets. The six all had undetectable insulin secretion, impaired hypoglycemic awareness, and severe hypoglycemia as the criterion to enter the phase 1/2 study.

“These new findings demonstrate the potential of stem cell–derived islets as a future treatment for patients with type 1 diabetes, signaling a new era that could potentially remove the need for exogenously administered insulin to achieve glycemic control,” said lead investigator Trevor W. Reichman, MD, PhD, surgical director of Pancreas and Islet Cell Transplantation at the University of Toronto.

Dr. Reichman presented the data at the annual scientific sessions of the American Diabetes Association, as an update to the report of the first two patients at last year’s ADA meeting. “We are hopeful that this first-of-its-kind research could be a game-changer for the treatment of type 1 diabetes,” he emphasized.

Co-investigator Maria Cristina Nostro, PhD, senior scientist at McEwen Stem Cell Institute, Toronto, told this news organization: “The clinical trial data are extremely exciting ... I think what was very beautiful is the glucose tolerance test where the insulin secretion was almost like a person without type 1 diabetes. For someone who is in the lab doing basic science research ... all the work we’ve put into this, it’s a labor of love. We’ve been trying to generate the cells for so long, and now to see this, it’s fantastic.”  
 

Two meet primary endpoint, three more on the right path

The six patients had a mean age of 44 years and mean 23 years’ diabetes duration. Three each were male and female. Their mean baseline A1c was 8.1%, and fasting C-peptide was undetectable. They had experienced a mean of 3.3 severe hypoglycemia episodes in the year prior to receiving the infusion, which was delivered to the portal vein similarly to the procedure with cadaveric donor islets, Dr. Reichman said.

The first two patients, including the one who dropped out, received half target doses of VX-880 (trial part A), while the rest, enrolled sequentially (part B), were each administered the full target dose of VX-880 given as a single infusion.

Induction with anti-thymocyte globulin and maintenance immunosuppressants, tacrolimus/sirolimus, was used to protect the cells from the recipient’s immune system. After the infusion, all six participants had C-peptide production, reduction in A1c despite reduced insulin use, and no severe hypoglycemia episodes from day 90 onwards.

Both participants with at least a year of follow-up met the criteria for the primary endpoint of A1c less than 7% with no severe hypoglycemic episodes. The first participant had an A1c of 5.3% at month 21, and the second 6.0% at 12 months. Both had sustained glucose-responsive insulin production with a mixed-meal tolerance test and exceeded the ADA target of more than 70% time-in blood glucose range assessed with continuous glucose monitoring.  
 

 

 

Safety: No major concerns thus far

Among all six, adverse events included elevations in the liver enzyme transaminase, occurring shortly after VX-880 infusion that were transient and resolved. No serious adverse events were considered related to the therapy.

Regarding safety, Dr. Nostro said, “With this trial, I have no concerns, because they’re using immunosuppression, so should anything go bad, you remove immunosuppression and the cells would be destroyed by the immune system. So it’s a perfect trial in a way.”

However, she noted, “Moving forward, as we develop something that will be genetically modified ... I think this is the future, because if you’re going to treat people with type 1 diabetes, we have to eliminate the immune suppression. I think the concern would be making sure the genetically modified cells are safe.”

Dr. Nostro, who gave an introductory presentation at the beginning of the symposium where the VX-880 data were presented, explained that in a current trial of genetically modified cells, “they’re placing the product inside a device so that the cells would be retrievable. It might not be perfect, but at least it’s going to tell us whether the genetically modified product is safe, which I think is what we need to use.”

In her talk, Dr. Nostro also summarized ongoing work in this field involving efforts to improve the generation of stem cell–derived islets with no “off target” non-beta cells to ensure consistency, optimization of engraftment, and elimination of immunosuppression. “[VX-880] is the beginning. This is the first product that’s going to be in the clinic, but I can imagine how 5, 10 years from now we will have different and more enhanced solutions for type 1 diabetes and who knows, maybe even for type 2.” 

Based on the data so far, the VX-880 trial is now moving to part C, in which 10 concurrently enrolled participants will receive the full target dose of the product. The trial, previously exclusively in the United States, has now expanded to additional sites in Norway, Switzerland, and the Netherlands. 

The study was funded by Vertex. Dr. Reichman is on advisory boards for Vertex and Sernova. Dr. Nostro was a consultant for Sigilon Therapeutics from 2018-2022, currently receives research support from Universal Cells, and has a patent licensed to Sernova.

Once-weekly basal insulin nears market for type 2 diabetes

The investigational once-weekly insulin icodec provided superior glucose control, compared with the once-daily basal insulins degludec and glargine in type 2 diabetes, results from two new phase 3a studies suggest.

Data from Novo Nordisk’s ONWARDS 1, comparing once-weekly icodec with once-daily glargine, and ONWARDS 3, comparing once-weekly icodec with daily degludec (Tresiba, Novo Nordisk), both in insulin-naive patients with type 2 diabetes, were presented at the annual scientific sessions of the American Diabetes Association.

In both trials, primary endpoints of superiority and noninferiority in A1c reduction were achieved, and in ONWARDS 1, patients spent more time in target blood glucose range.

“I feel that weekly insulins have the potential to become transformational as preferred options for basal insulin replacement in people with type 2 diabetes in need of initiation of insulin therapy,” said Julio Rosenstock, MD, the lead author of ONWARDS 1.

Asked to comment, independent diabetes industry consultant Charles Alexander, MD, said: “The data certainly support approval of Icodec.”

Dr. Alexander said that an ideal candidate for once-weekly insulin “is someone who’s already on once-weekly [glucagon-like peptide-1 (GLP-1) agonist]. Then, taking your GLP-1 [agonist] and your basal insulin at the same time once a week makes a lot of sense ... Since they’re taking a weekly injection anyway, it’s relatively easy for a person to remember ‘When I take my weekly GLP-1 [agonist], I’ll take my weekly basal insulin.’ ”

However, he also pointed out: “Payers may say they don’t care about the convenience of once-weekly and they prefer to pay for the cheaper daily basal [insulin] ... I think a lot of people will continue to use [insulin] glargine because it is cheaper than either degludec or icodec.”

The data from ONWARDS 1 was published in the New England Journal of Medicine, and the data from ONWARDS 3 was published in JAMA.

Six ONWARDS trials make up Novo Nordisk’s phase 3a clinical development program comparing the efficacy and safety of once-weekly insulin icodec with once-daily basal insulin comparators.

Previously, findings from ONWARDS 2, in which patients with type 2 diabetes taking basal insulin had improved A1c after being switched to once-weekly icodec or once-daily degludec, were presented at the annual meeting of the European Association for the Study of Diabetes.    

Insulin icodec has been submitted for regulatory review in the United States, Canada, Europe, China, Australia, Switzerland, and Brazil, with decisions anticipated starting in the first half of 2024.
 

Hypoglycemia: Is the slight increase clinically significant?

One concern about the once-weekly insulins is that they might result in higher rates of hypoglycemia because they stay active in the body for so long.

Differences in rates of combined level 2 (clinically significant) and level 3 (severe) hypoglycemia were increased with borderline significance in ONWARDS 1.

In ONWARDS 3 there was a threefold significant difference, but the overall risk was still low, equating to one episode per patient per 3 years, said Ildiko Lingvay, MD, of University of Texas Southwestern Medical Center, Dallas, who is lead author for ONWARDS 1 and a co-author for ONWARDS 3.

Dr. Ildiko Lingvay


“Insulin is insulin. When we use insulin there will always be hypoglycemia. But we only have less than one event per year,” added Dr. Rosenstock, of Velocity Clinical Research at Medical City, Dallas.

Dr. Alexander pointed out that in ONWARDS 3 just under half of both groups were taking a sulfonylurea, although the trial design allowed for cutting the dose in half when the basal insulin was added.

In ONWARDS 1, in contrast, sulfonylureas and glinides were stopped at the time of randomization. “That’s not definitive, but I would argue that’s the explanation, to be proven by formal testing.”

Indeed, an audience member asked about that during the discussion, and Dr. Lingvay said they were still analyzing those data. “We’re working on that. It’s very important.”

Dr. Alexander noted, “I think the message here is don’t continue sulfonylureas or glinides in someone you’re giving insulin to because you’re going to get hypoglycemia.”
 

 

 

Better glycemic control, with fewer injections

ONWARDS 1 was a 78-week, randomized, open-label, treat-to-target trial, with a main 52-week phase and a 26-week extension phase. A total of 984 patients with type 2 diabetes and A1c 7%-11% with no prior insulin treatment were randomized 1:1 to once-weekly icodec or daily insulin glargine. All baseline medications except sulfonylureas and glinides were continued.

The primary endpoint was change in A1c from baseline to week 52, and this dropped from 8.5% to 6.9% with icodec, versus 8.4% to 7.1% with glargine, a significant difference, confirming both noninferiority (P < .001) and superiority (P = .02) of icodec, Dr. Rosenstock said.

The percentage of time in blood glucose range (70-180 mg/dL) was also significantly higher with icodec than glargine (71.9% vs. 66.9%; P < .001), also confirming superiority.

Rates of combined clinically significant or severe hypoglycemia at 83 weeks were 0.30 versus 0.16 events per person-year of exposure at week 83 (P = .043). No new safety signals were identified, and incidences of adverse events were similar in the two groups.

A significantly higher proportion of participants achieved an A1c of less than 7% without clinically significant or severe hypoglycemia with once-weekly basal insulin icodec versus once-daily basal insulin glargine (52.6% vs. 42.6%).

ONWARDS 3 randomized 588 patients each to once-weekly insulin icodec plus once-weekly placebo or once-daily insulin degludec plus once-weekly placebo. The primary endpoint, change in A1c from baseline to week 26, fell from 8.6% to 7.0% with icodec and from 8.5% to 7.2% with degludec, confirming both noninferiority (P < .001) and superiority (P = .002).

There were no significant differences between the two insulins in change in fasting plasma glucose, mean weekly insulin dose, or body weight.

Combined level 2 or 3 hypoglycemia rates were numerically higher in the icodec group than in the degludec group from week 0 to 31 (0.31 vs. 0.15 events per patient-year exposure; P = .11) and statistically higher in the icodec group from week 0 to 26 (0.35 vs. 0.12 events per patient-year exposure; P = .01).  

The percentage of patients achieving an A1c of less than 7% without level 2 or 3 hypoglycemia was 52.1% with icodec versus 39.9% with degludec.

Dr. Lingvay and Dr. Rosenstock have reported financial relationships with multiple companies.

Asked to comment, independent diabetes industry consultant Charles Alexander, MD, said: “The data certainly support approval of Icodec.”

Dr. Alexander said that an ideal candidate for once-weekly insulin “is someone who’s already on once-weekly [glucagon-like peptide-1 (GLP-1) agonist]. Then, taking your GLP-1 [agonist] and your basal insulin at the same time once a week makes a lot of sense ... Since they’re taking a weekly injection anyway, it’s relatively easy for a person to remember ‘When I take my weekly GLP-1 [agonist], I’ll take my weekly basal insulin.’ ”

However, he also pointed out: “Payers may say they don’t care about the convenience of once-weekly and they prefer to pay for the cheaper daily basal [insulin] ... I think a lot of people will continue to use [insulin] glargine because it is cheaper than either degludec or icodec.”

The data from ONWARDS 1 was published in the New England Journal of Medicine, and the data from ONWARDS 3 was published in JAMA.

Six ONWARDS trials make up Novo Nordisk’s phase 3a clinical development program comparing the efficacy and safety of once-weekly insulin icodec with once-daily basal insulin comparators.

Previously, findings from ONWARDS 2, in which patients with type 2 diabetes taking basal insulin had improved A1c after being switched to once-weekly icodec or once-daily degludec, were presented at the annual meeting of the European Association for the Study of Diabetes.    

Insulin icodec has been submitted for regulatory review in the United States, Canada, Europe, China, Australia, Switzerland, and Brazil, with decisions anticipated starting in the first half of 2024.
 

Hypoglycemia: Is the slight increase clinically significant?

One concern about the once-weekly insulins is that they might result in higher rates of hypoglycemia because they stay active in the body for so long.

Differences in rates of combined level 2 (clinically significant) and level 3 (severe) hypoglycemia were increased with borderline significance in ONWARDS 1.

In ONWARDS 3 there was a threefold significant difference, but the overall risk was still low, equating to one episode per patient per 3 years, said Ildiko Lingvay, MD, of University of Texas Southwestern Medical Center, Dallas, who is lead author for ONWARDS 1 and a co-author for ONWARDS 3.

“Insulin is insulin. When we use insulin there will always be hypoglycemia. But we only have less than one event per year,” added Dr. Rosenstock, of Velocity Clinical Research at Medical City, Dallas.

Dr. Alexander pointed out that in ONWARDS 3 just under half of both groups were taking a sulfonylurea, although the trial design allowed for cutting the dose in half when the basal insulin was added.

In ONWARDS 1, in contrast, sulfonylureas and glinides were stopped at the time of randomization. “That’s not definitive, but I would argue that’s the explanation, to be proven by formal testing.”

Indeed, an audience member asked about that during the discussion, and Dr. Lingvay said they were still analyzing those data. “We’re working on that. It’s very important.”

Dr. Alexander noted, “I think the message here is don’t continue sulfonylureas or glinides in someone you’re giving insulin to because you’re going to get hypoglycemia.”
 

 

 

Better glycemic control, with fewer injections

ONWARDS 1 was a 78-week, randomized, open-label, treat-to-target trial, with a main 52-week phase and a 26-week extension phase. A total of 984 patients with type 2 diabetes and A1c 7%-11% with no prior insulin treatment were randomized 1:1 to once-weekly icodec or daily insulin glargine. All baseline medications except sulfonylureas and glinides were continued.

The primary endpoint was change in A1c from baseline to week 52, and this dropped from 8.5% to 6.9% with icodec, versus 8.4% to 7.1% with glargine, a significant difference, confirming both noninferiority (P < .001) and superiority (P = .02) of icodec, Dr. Rosenstock said.

The percentage of time in blood glucose range (70-180 mg/dL) was also significantly higher with icodec than glargine (71.9% vs. 66.9%; P < .001), also confirming superiority.

Rates of combined clinically significant or severe hypoglycemia at 83 weeks were 0.30 versus 0.16 events per person-year of exposure at week 83 (P = .043). No new safety signals were identified, and incidences of adverse events were similar in the two groups.

A significantly higher proportion of participants achieved an A1c of less than 7% without clinically significant or severe hypoglycemia with once-weekly basal insulin icodec versus once-daily basal insulin glargine (52.6% vs. 42.6%).

ONWARDS 3 randomized 588 patients each to once-weekly insulin icodec plus once-weekly placebo or once-daily insulin degludec plus once-weekly placebo. The primary endpoint, change in A1c from baseline to week 26, fell from 8.6% to 7.0% with icodec and from 8.5% to 7.2% with degludec, confirming both noninferiority (P < .001) and superiority (P = .002).

There were no significant differences between the two insulins in change in fasting plasma glucose, mean weekly insulin dose, or body weight.

Combined level 2 or 3 hypoglycemia rates were numerically higher in the icodec group than in the degludec group from week 0 to 31 (0.31 vs. 0.15 events per patient-year exposure; P = .11) and statistically higher in the icodec group from week 0 to 26 (0.35 vs. 0.12 events per patient-year exposure; P = .01).  

The percentage of patients achieving an A1c of less than 7% without level 2 or 3 hypoglycemia was 52.1% with icodec versus 39.9% with degludec.

Dr. Lingvay and Dr. Rosenstock have reported financial relationships with multiple companies.

ADA: Screen all with type 2 diabetes for fatty liver disease

Article Type
Changed
Tue, 06/27/2023 - 16:16

The American Diabetes Association now advises universal screening of people with type 2 diabetes and prediabetes for fatty liver disease and provides new recommendations for management in those with the condition or who are at risk for it.

Liver disease affects up to 70% of people with type 2 diabetes and is common in people with prediabetes and in those with type 1 diabetes who also have obesity. Non-alcoholic fatty liver disease (NAFLD) is the most common form of liver disease in people with diabetes. It can lead to cirrhosis and liver cancer and is associated with an increased risk for cardiovascular disease and death. The condition includes non-alcoholic steatohepatitis (NASH).

“The ADA has recognized that this has become a big problem for their patients because NASH is becoming the number one cause of cirrhosis in people with type 2 diabetes and the number one cause of liver transplantation in the United States, so we have to do something about it,” Kenneth Cusi, MD, who presented a summary of the new guidance at the annual scientific sessions of the American Diabetes Association, said in an interview. 

The new ADA guidance was published as a mid-year update to the ADA’s Standards of Care in Diabetes–2023 in the section on “Comprehensive Medical Evaluation and Assessment of Comorbidities.”

Asked to comment, Atlanta endocrinologist Scott Isaacs, MD, said, “It is wonderful to see that the ADA has recognized NAFLD ... as the hepatic complication of type 2 diabetes and has updated the Standards of Care reflecting the current knowledge and evidence of this ubiquitous and often silent disease.”

The new ADA guidance aligns with those of other professional societies, including the American Association for the Study of Liver Diseases, the American Gastroenterological Society, and the American Association of Clinical Endocrinology.

Dr. Isaacs, who chaired the AACE guidance writing panel, noted, “The ADA update essentially repeats the same guidance in the AACE and AASLD documents. It is excellent to see this type of alignment of guidance among the major organizations.”
 

FIB-4: Easy calculation in the EHR

The ADA now advises screening all adults with type 2 diabetes or prediabetes, particularly those with obesity or cardiometabolic risk factors or established cardiovascular disease – even those with normal liver enzyme levels. People with type 1 diabetes who have obesity and/or cardiovascular risk factors are also to be screened for NAFLD.

The recommended screening tool is the fibrosis-4 index (FIB-4), a calculation that includes the patient’s age, liver enzyme levels, and platelet counts. A score of 1.3 or higher is considered high risk for clinically significant fibrosis and above 2.6 is very high-risk.

Dr. Cusi noted, “The reason we advise using the FIB-4 ... instead of liver enzymes as ADA advised in the past, is that now we know that 70% of people with type 2 diabetes have steatosis already and about one in five have fibrosis, but if you go by liver enzymes you will miss most of them. Liver enzymes are ineffective as a screening tool.”

The FIB-4 is “a simple tool we already have in our electronic health records (EHR) but we’re just simply not using it,” noted Dr. Cusi, chief of endocrinology, diabetes, and metabolism at the University of Florida, Gainesville. 

Indeed, Dr. Isaacs said, “The FIB-4 is a simple ... great screening test because it is essentially free.” But he cautioned that it has some limitations.

“It is a good test for ruling out advanced liver disease but can have false positives and false negatives. The FIB-4 cutoffs need to be adjusted for persons over 65 years old and [should] not to be used for persons under 30 years old.”

Dr. Isaacs also pointed out that, while the calculation can be done from a website, “even this adds time to a clinician’s busy day. Ideally, the FIB-4 should be automatically calculated in the EHR or on the lab report, similar to the [estimated glomerular filtration rate] calculation [for kidney function] and flagged if greater than 1.3.”

The ADA update also provides guidance on follow-up for patients flagged with the FIB-4, including when referral to a gastroenterologist or hepatologist is appropriate.
 

 

 

Treatment: Lifestyle modification plus GLP-1 agonists or pioglitazone

Lifestyle modification is recommended for all adults with diabetes or prediabetes and NAFLD, particularly those with overweight or obesity.  

In addition, the ADA now advises consideration of a using a glucagonlike peptide–1 (GLP-1) agonist with demonstrated benefits in NAFLD as adjunctive therapy to lifestyle interventions for weight loss in those with type 2 diabetes, particularly with overweight/obesity.

And for those with biopsy-proven NASH or who are identified with clinically significant liver fibrosis using non-invasive tests, either a GLP-1 agonist or pioglitazone are the “preferred treatments.”

However, insulin is the preferred treatment for hyperglycemia in adults with type 2 diabetes who have decompensated cirrhosis.

Dr. Isaacs commented, “Pioglitazone has so many benefits and a few known risks ... it is an underused medication. It is very inexpensive. Pioglitazone should be considered as a first line treatment for patients with type 2 diabetes and NAFLD.”

The ADA update also advises statin therapy for people with type 2 diabetes and NAFLD, given their increased cardiovascular risk. However, statins are not recommended for people with decompensated cirrhosis because of limited safety and efficacy data.

Dr. Cusi noted that he has been advocating for fatty liver screening in people with type 2 diabetes for over a decade.

“Doctors have already been adopting it, but ADA as an organization in diabetes care has a big impact. I dreamed many years ago that the day would come when we would screen all people with type 2 diabetes, and that day is today.”

Dr. Cusi is a consultant for Altimmune, Akero, Arrowhead, AstraZeneca, 89Bio, BMS, Coherus, Intercept, Lilly, Madrigal, Merck, Novo Nordisk, Quest, Sagimet, Sonic Incytes, Terns, Thera Technologies, and MSD. Dr. Isaacs reports no relevant financial relationships.

Triple-agonist retatrutide hits new weight loss highs

Article Type
Changed
Wed, 07/05/2023 - 12:08

– New designer molecules that target weight loss via multiple mechanisms continue to raise the bar of how many pounds people with overweight or obesity can lose.

Retatrutide (Eli Lilly), an investigational agent that combines agonism to three key hormones that influence eating and metabolism into a single molecule, safely produced weight loss at levels never seen before in a pair of phase 2 studies that together randomized more than 600 people with overweight or obesity, with or without type 2 diabetes.

Among 338 randomized people with overweight or obesity and no type 2 diabetes, 48 weeks of treatment with retatrutide at a 12-mg dose given by weekly subcutaneous injection (the highest dose tested) safely produced an average 24% drop from baseline bodyweight.

Among 281 randomized people with overweight or obesity and type 2 diabetes, the same dose of retatrutide produced a nearly 17% cut in weight from baseline after 36 weeks of treatment.
 

Never before seen weight loss

“I have never seen weight loss at this level” after nearly 1 year of treatment, Ania M. Jastreboff, MD, PhD, who led the obesity study, said during a press briefing at the annual scientific sessions of the American Diabetes Association.

Dr. Ania M. Jastreboff

The average weight loss by study participants taking high-dose retatrutide in the two studies “is really impressive, way beyond my wildest dreams,” said Carel le Roux, MBChB, PhD, an obesity and diabetes researcher at University College Dublin, Ireland, who was not involved with the retatrutide studies.

And Robert A. Gabbay, MD, chief scientific and medical officer of the ADA, called the results “stunning,” and added, “we are now witnessing the first triple-hormone combination being highly effective for not only weight loss but liver disease and diabetes.”

Joslin Diabetes Center
Dr. Robert A. Gabbay


A prespecified subgroup analysis of the obesity study showed that at both 8-mg and 12-mg weekly doses, 24 weeks of retatrutide produced complete resolution of excess liver fat (hepatic steatosis) in about 80% of the people eligible for the analysis (those with at least 10% of their liver volume as fat at study entry); that figure increased to about 90% of people on these doses after 48 weeks, Lee M. Kaplan, MD, reported during a separate presentation at the meeting.
 

Adding glucagon agonism ups liver-fat clearance

“When you add glucagon activity,” one of the three agonist actions of retatrutide, “liver-fat clearance goes up tremendously,” said Dr. Kaplan, director of the Obesity, Metabolism and Nutrition Institute at Massachusetts General Hospital in Boston.

Dr. Lee M. Kaplan

“To my knowledge, no mono-agonist of the glucagon-like peptide-1 (GLP-1) receptor [such as semaglutide or liraglutide] produces more than 50% clearance of liver fat,” added Dr. Kaplan.

The separate, randomized study of people with type 2 diabetes showed that in addition to producing an unprecedented average level of weight loss at the highest retatrutide dose, the agent also produced an average reduction from baseline levels of A1c of about 2 percentage points, an efficacy roughly comparable to maximum doses of the most potent GLP-1 mono-agonist semaglutide (Ozempic, Novo Nordisk), as well as by tirzepatide (Mounjaro, Eli Lilly), a dual agonist for the GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptors.

“No other medication has shown an average 17% reduction from baseline bodyweight after 36 weeks in people with type 2 diabetes,” said Julio Rosenstock, MD, director of the Dallas Diabetes Research Center at Medical City, Texas, who presented the results from the type 2 diabetes study of retatrutide.

For the obesity study, people with a body mass index of 27-50 kg/m2 and no diabetes were randomized to placebo or any of four retatrutide target dosages using specified dose-escalation protocols. Participants were an average of 48 years old, and by design, 52% were men. (The study sought to enroll roughly equal numbers of men and women.) Average BMI at study entry was 37 kg/m2.

Weight loss levels after 24 and 48 weeks of retatrutide treatment followed a clear dose-related pattern. (Weight loss averaged about 2% among the 70 controls who received placebo.)
 

 

 

Twenty-six percent without diabetes lost at least 30% of body weight

Every person who escalated to receive the 8-mg or 12-mg weekly dose of retatrutide lost at least 5% of their bodyweight after 48 weeks, 83% of those taking the 12-mg dose lost at least 15%, 63% of those on the 12-mg dose lost at least 20%, and 26% of those on the highest dose lost at least 30% of their starting bodyweight, reported Dr. Jastreboff, director of the Yale Obesity Research Center of Yale University in New Haven, Conn.

The highest dose was also associated with an average 40% relative reduction in triglyceride levels from baseline and an average 22% relative drop in LDL cholesterol levels.

The results were simultaneously published online in the New England Journal of Medicine.

The incidence of serious adverse events with retatrutide was low, similar to the rate in those who received placebo, and showed no dose relationship.

The most common adverse events were gastrointestinal, in as many as 16% of those on the highest dose; these were mild to moderate in severity and usually occurred during dose escalation. In general, adverse events were comparable to what is seen with a GLP-1 agonist or the dual agonist tirzepatide, Dr. Jastreboff said.
 

A1c normalization in 26% at the highest dose

A similar safety pattern occurred in the study of people with type 2 diabetes, which randomized people with an average A1c of 8.3% and an average BMI of 35.0 kg/m2. After 36 weeks of treatment, the 12-mg weekly dose of retatrutide led to normalization of A1c < 5.7% in 27% of people and A1c ≤ 6.5% in 77%.

“The number of people we were able to revert to a normal A1c was impressive,” said Dr. Rosenstock. These results were simultaneously published online in The Lancet.

The additional findings on liver-fat mobilization in people without diabetes enrolled in the obesity study are notable because no agent currently has labeling from the Food and Drug Administration for the indication of reducing excess liver fat, said Dr. Kaplan.

The researchers measured liver fat at baseline and then during treatment using MRI.

“With the level of fat clearance from the liver that we see with retatrutide it is highly likely that we’ll also see improvements in liver fibrosis” in retatrutide-treated patients, Dr. Kaplan predicted.

Next up for retatrutide is testing in pivotal trials, including the TRIUMPH-3 trial that will enroll about 1,800 people with severe obesity and cardiovascular disease, with findings expected toward the end of 2025.

The retatrutide studies are sponsored by Eli Lilly. Dr. Jastreboff, Dr. Rosenstock, Dr. Kaplan, and Dr. Le Roux have reported financial relationships with Eli Lilly as well as other companies.

The average weight loss by study participants taking high-dose retatrutide in the two studies “is really impressive, way beyond my wildest dreams,” said Carel le Roux, MBChB, PhD, an obesity and diabetes researcher at University College Dublin, Ireland, who was not involved with the retatrutide studies.

And Robert A. Gabbay, MD, chief scientific and medical officer of the ADA, called the results “stunning,” and added, “we are now witnessing the first triple-hormone combination being highly effective for not only weight loss but liver disease and diabetes.”

A prespecified subgroup analysis of the obesity study showed that at both 8-mg and 12-mg weekly doses, 24 weeks of retatrutide produced complete resolution of excess liver fat (hepatic steatosis) in about 80% of the people eligible for the analysis (those with at least 10% of their liver volume as fat at study entry); that figure increased to about 90% of people on these doses after 48 weeks, Lee M. Kaplan, MD, reported during a separate presentation at the meeting.
 

Adding glucagon agonism ups liver-fat clearance

“When you add glucagon activity,” one of the three agonist actions of retatrutide, “liver-fat clearance goes up tremendously,” said Dr. Kaplan, director of the Obesity, Metabolism and Nutrition Institute at Massachusetts General Hospital in Boston.

Dr. Lee M. Kaplan

“To my knowledge, no mono-agonist of the glucagon-like peptide-1 (GLP-1) receptor [such as semaglutide or liraglutide] produces more than 50% clearance of liver fat,” added Dr. Kaplan.

The separate, randomized study of people with type 2 diabetes showed that in addition to producing an unprecedented average level of weight loss at the highest retatrutide dose, the agent also produced an average reduction from baseline levels of A1c of about 2 percentage points, an efficacy roughly comparable to maximum doses of the most potent GLP-1 mono-agonist semaglutide (Ozempic, Novo Nordisk), as well as by tirzepatide (Mounjaro, Eli Lilly), a dual agonist for the GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptors.

“No other medication has shown an average 17% reduction from baseline bodyweight after 36 weeks in people with type 2 diabetes,” said Julio Rosenstock, MD, director of the Dallas Diabetes Research Center at Medical City, Texas, who presented the results from the type 2 diabetes study of retatrutide.

For the obesity study, people with a body mass index of 27-50 kg/m2 and no diabetes were randomized to placebo or any of four retatrutide target dosages using specified dose-escalation protocols. Participants were an average of 48 years old, and by design, 52% were men. (The study sought to enroll roughly equal numbers of men and women.) Average BMI at study entry was 37 kg/m2.

Weight loss levels after 24 and 48 weeks of retatrutide treatment followed a clear dose-related pattern. (Weight loss averaged about 2% among the 70 controls who received placebo.)
 

 

 

Twenty-six percent without diabetes lost at least 30% of body weight

Every person who escalated to receive the 8-mg or 12-mg weekly dose of retatrutide lost at least 5% of their bodyweight after 48 weeks, 83% of those taking the 12-mg dose lost at least 15%, 63% of those on the 12-mg dose lost at least 20%, and 26% of those on the highest dose lost at least 30% of their starting bodyweight, reported Dr. Jastreboff, director of the Yale Obesity Research Center of Yale University in New Haven, Conn.

The highest dose was also associated with an average 40% relative reduction in triglyceride levels from baseline and an average 22% relative drop in LDL cholesterol levels.

The results were simultaneously published online in the New England Journal of Medicine.

The incidence of serious adverse events with retatrutide was low, similar to the rate in those who received placebo, and showed no dose relationship.

The most common adverse events were gastrointestinal, in as many as 16% of those on the highest dose; these were mild to moderate in severity and usually occurred during dose escalation. In general, adverse events were comparable to what is seen with a GLP-1 agonist or the dual agonist tirzepatide, Dr. Jastreboff said.
 

A1c normalization in 26% at the highest dose

A similar safety pattern occurred in the study of people with type 2 diabetes, which randomized people with an average A1c of 8.3% and an average BMI of 35.0 kg/m2. After 36 weeks of treatment, the 12-mg weekly dose of retatrutide led to normalization of A1c < 5.7% in 27% of people and A1c ≤ 6.5% in 77%.

“The number of people we were able to revert to a normal A1c was impressive,” said Dr. Rosenstock. These results were simultaneously published online in The Lancet.

The additional findings on liver-fat mobilization in people without diabetes enrolled in the obesity study are notable because no agent currently has labeling from the Food and Drug Administration for the indication of reducing excess liver fat, said Dr. Kaplan.

The researchers measured liver fat at baseline and then during treatment using MRI.

“With the level of fat clearance from the liver that we see with retatrutide it is highly likely that we’ll also see improvements in liver fibrosis” in retatrutide-treated patients, Dr. Kaplan predicted.

Next up for retatrutide is testing in pivotal trials, including the TRIUMPH-3 trial that will enroll about 1,800 people with severe obesity and cardiovascular disease, with findings expected toward the end of 2025.

The retatrutide studies are sponsored by Eli Lilly. Dr. Jastreboff, Dr. Rosenstock, Dr. Kaplan, and Dr. Le Roux have reported financial relationships with Eli Lilly as well as other companies.

– New designer molecules that target weight loss via multiple mechanisms continue to raise the bar of how many pounds people with overweight or obesity can lose.

Retatrutide (Eli Lilly), an investigational agent that combines agonism to three key hormones that influence eating and metabolism into a single molecule, safely produced weight loss at levels never seen before in a pair of phase 2 studies that together randomized more than 600 people with overweight or obesity, with or without type 2 diabetes.

Among 338 randomized people with overweight or obesity and no type 2 diabetes, 48 weeks of treatment with retatrutide at a 12-mg dose given by weekly subcutaneous injection (the highest dose tested) safely produced an average 24% drop from baseline bodyweight.

Among 281 randomized people with overweight or obesity and type 2 diabetes, the same dose of retatrutide produced a nearly 17% cut in weight from baseline after 36 weeks of treatment.

Children with type 2 diabetes face dire complications as young adults

Article Type

Tue, 06/27/2023 - 08:32

Children with type 2 diabetes face a strikingly high complication rate as they age into young adulthood, with an 80% incidence of at least one vascular complication during up to 15 years of follow-up, show findings from the TODAY prospective, longitudinal study of 699 U.S. children newly diagnosed with type 2 diabetes.

Arterial stiffness and worsened cardiac function often appear in these children within 2-5 years of diagnosis and seem driven in part by the development of hypertension and worsening hemoglobin A1c levels, said Rachelle G. Gandica, MD, at the annual scientific sessions of the American Diabetes Association.

Indeed, an A1c greater than 6.2% at study entry generally predicts these children will fail treatment and is a red flag, said Dr. Gandica. “I teach fellows this all the time, that if a child’s A1c is above 6.2% they will fail, and you have to watch for that,” she noted.

Dr. Rachelle G. Gandica

The results from the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study showed, for example, an overall cardiovascular event rate of 3.7/1,000 patient-years in a population that had just reached an average age of 26 years old, with type 2 diabetes diagnosed for an average of more than 13 years.

During follow-up, there were six cases of congestive heart failure, four myocardial infarctions, four strokes, and three cases of coronary artery disease in the cohort. Hypertension ballooned from a prevalence of 19% at study entry to 68% by the end of follow-up.

Dr. Gandica called these and other findings “sobering details” that document the toll type 2 diabetes takes on children, who averaged 14 years old at the time they entered the study – when their diabetes had been diagnosed for an average of about 8 months – and then underwent an average 12.6 years of follow-up.

Investigators also found:

  • After more than 12 years of type 2 diabetes, 49% of the cohort had developed diabetic retinopathy, with 3.5% having macular edema.
  • Kidney damage (diabetic nephropathy) affected 8% of the cohort at entry, and then increased to a prevalence of 55% after up to 14 years of follow-up.
  • Among the 452 girls who entered the study, 141 (31%) later became pregnant, with a total of 260 pregnancies. A quarter of the pregnancies resulted in preterm deliveries (43% went to term), 25% resulted in miscarriage or fetal demise, with the remaining 8% having elective terminations or unknown outcomes.
  • Complications in neonates were common, including hypoglycemia (29%), respiratory disorder (19%), and cardiac issues (10%).

Dire prognosis a reason to aggressively treat these patients

It has become apparent from this and other studies in youth with type 2 diabetes that the difference in outcomes between youth and adults is stark and could indicate that type 2 diabetes in childhood or adolescence likely has a different underlying pathology and natural history, with a more aggressive disease course.

The dire prognosis is therefore a reason to aggressively treat these patients with antidiabetic medications from drug classes with proven cardiovascular disease protection, specifically sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagonlike peptide-1 (GLP-1) agonists, said Dr. Gandica, a pediatric endocrinologist at Columbia University Medical Center in New York.

“It’s fair to say we now more aggressively use [these agents] in children,” she said in an interview, and noted the very recent approval, just last week, by the U.S. Food and Drug Administration of the SGLT2 inhibitor empagliflozin (Jardiance, Boehringer Ingelheim/Lilly) for children as young as 10 years.

“I look forward to prescribing empagliflozin to children with type 2 diabetes to lower their blood pressure and get additional cardiovascular disease benefits,” Dr. Gandica said.

Other newer type 2 diabetes medications approved for U.S. children in the past few years include the once-weekly injectable GLP-1 agonist exenatide extended release (Bydureon/Bydureon BCise, AstraZeneca) for children with type 2 diabetes aged 10 and older, in 2021, and the daily injectable GLP-1 agonist liraglutide (Victoza, Novo Nordisk) in 2019.
 

 

 

A1c spike heralds treatment failure: ‘Watch for that’

TODAY enrolled 699 children with type 2 diabetes for an average of 8 months since diagnosis at 16 U.S. sites starting in 2004. The protocol began with a run-in phase of up to 6 months, when participating children came off any preexisting antidiabetes medications and then began a metformin-only regimen to bring A1c below 8.0%. If achieved, patients were eligible to continue to randomization.

Participants were randomized to one of three treatment groups: metformin alone, metformin plus lifestyle interventions, or metformin plus rosiglitazone (Avandia, GSK). The primary endpoint was the incidence of treatment failure, defined as A1c that rose back above 8.0% for at least 6 months or persistent metabolic decompensation during initial follow-up, for an average of just under 4 years.

The results showed that only metformin plus rosiglitazone significantly surpassed metformin alone for preventing treatment failure, reported in 2012 in the New England Journal of Medicine

More recent reports on findings from longer-term follow-up have appeared in several journals, including the cardiovascular disease results, reported in 2021 also in the New England Journal of Medicine.

Another key finding from TODAY is the importance of A1c as a risk marker for impending treatment failure. Study findingsshow that an A1c of 6.2% or higher when children entered the study best predicted loss of glycemic control during follow-up. Also, a rise in A1c of at least 0.5 percentage points was significantly associated with loss of glycemic control within the following 3-6 months.

That’s an important message for clinicians, Dr. Gandica concluded.

TODAY and TODAY2 received no commercial funding. Dr. Gandica has reported no relevant financial relationships.

– Coadministration of the long-acting amylin analog cagrilintide plus the glucagonlike peptide–1 (GLP-1) agonist semaglutide, dubbed CagriSema, resulted in significantly greater weight loss, along with improved measures of glucose control, than either agent alone, in a small, short phase 2 trial of patients with type 2 diabetes. 

Juan P. Frias, MD, presented the findings at the annual scientific sessions of the American Diabetes Association, which were simultaneously published in The Lancet.

“Overall, in this phase 2 trial in people with type 2 diabetes, clinically relevant improvements in glycemic control – as assessed by [hemoglobin] A1c, [time in range], and other [continuous glucose monitoring (CGM)] measures – were observed with CagriSema, as well as weight loss of a magnitude not previously reported with pharmacotherapies in this population. CagriSema also had an acceptable safety profile,” the researchers summarized.

“These data support further investigation of CagriSema in people with type 2 diabetes in longer and larger phase 3 studies,” said Dr. Frias, from Velocity Clinical Research, Los Angeles.

In reply to audience questions, he said he was “pleasantly surprised” with the low gastrointestinal adverse events, which may have been related to the slower dosing titration. He also noted that patients in the study did not receive dietary counseling, unlike in the STEP-2 trial, where weight loss with semaglutide was greater than in this study.  

Time in normal blood glucose range in the CagriSema group went from 40% at baseline to 89% at week 32, Chantal Mathieu, MD, PhD, reported during a follow-up presentation that focused on the trial’s CGM findings.

“I was extremely happy that we were allowed to include CGM measurement because it does give you more information, especially in a short-term trial,” said Dr. Mathieu, from the Katholieke Universiteit Leuven (Belgium). The CGM data were collected for 10 days preceding baseline and at weeks 20 and 32.

“At this point in time, it is difficult to make a final determination” about potential future clinical applications, session chair Elisabetta Patorno, MD, DrPH, from Harvard Medical School, Boston, said in an interview. “This was a phase 2 randomized controlled trial, so more patients are needed.

“It’s very interesting what was found with the use of CGM, which makes us think whether they should always be part of [trials] versus the more traditional A1c assessment,” Dr. Patorno added.
 

‘Synergistic effect for both glycemic control and weight loss’

“CagriSema is the next in a series of gut hormone analogs with the potential to herald a new era in treating obesity and preventing diabesity,” the coexistence of type 2 diabetes and obesity, Caroline M. Apovian, MD, and Marie E. McDonnell, MD, both also from Harvard Medical School, wrote in an accompanying editorial in The Lancet.

Cagrilintide plus semaglutide each “effectively delay gastric emptying, suppress glucagon release, and are involved in the regulation of appetite and satiety in the brain,” they noted.

The results – a substantial difference in effect size between the combination drug and each component alone – show that “there is a synergistic effect for both glycemic control and weight loss.

“The weight loss seen in this phase 2 trial of CagriSema in 32 weeks could predict a phase 3 trial result over 1 year that might surpass that of semaglutide (14.9%) and tirzepatide (20.9%) in a population without type 2 diabetes, and might equal that of bariatric surgery (23.5%-30.4%),” they speculated.

However, it’s still early days, the editorialists cautioned. Study limitations include that it was a small trial and the mean duration of type 2 diabetes at baseline was shorter in the CagriSema group (6.4 years) than in the semaglutide or cagrilintide alone groups (9.2 years and 10.7 years, respectively).

The rate of gastrointestinal adverse events was also higher in the CagriSema group (58%) than in the other two groups (about 33%). However, the adverse events “were all mild or moderate and not severe enough to lead to participant withdrawal,” they noted. “Remarkably, only one participant, from the semaglutide group, withdrew due to adverse events during the 32-week trial across all groups.

“Although bariatric surgery remains the most effective treatment for severe obesity, offering the most robust weight reduction, remission of type 2 diabetes, and reduced cardiovascular mortality,” the study suggests that “combination metabolic hormonal therapy could offer all three of these outcomes in the near future,” Dr. Apovian and Dr. McDonnell wrote.
 

92 patients randomized to three treatments

In the study, researchers randomized 92 adults with type 2 diabetes and a body mass index of at least 27 kg/m2 taking metformin alone (73%) or metformin plus a sodium-glucose cotransporter 2 inhibitor (27%), at 17 sites in the United States, between August and October 2021.

Patients were a mean age of 58 years and 64% were men. Mean A1c was 8.4% and mean bodyweight was 106 kg (234 lb).

They were randomized 1:1:1 to receive up to maximal once-weekly doses of 2.4 mg semaglutide and 2.4 mg cagrilintide (CagriSema, given in two injector pens), 2.4 mg semaglutide (plus placebo), or 2.4 mg cagrilintide (plus placebo).

Both cagrilintide and semaglutide are manufactured by the Danish company Novo Nordisk. Semaglutide is already approved in the United States for type 2 diabetes, as Ozempic, and as the weight-loss drug Wegovy. Cagrilintide is not yet approved.

Treatment doses were escalated every 4 weeks from 0.25 to 0.5 to 1.0 to 1.7 mg to a maintenance dose of 2.4 mg at 16 weeks. Patients then entered a 16-week maintenance phase followed by a 5-week follow-up period.

Among the key findings, the reduction in A1c at 32 weeks, compared with baseline (primary outcome), was –2.2% with CagriSema, –1.8% with semaglutide, and –0.9% with cagrilintide, but was not significantly greater with CagriSema versus semaglutide (–0.4%; P = .07).

However, in a secondary outcome, there was a significantly greater difference in A1c at 32 weeks with CagriSema versus cagrilintide (–1.3%; P < .0001). Moreover, 89% of patients in the CagriSema group reached an A1c less than 7%.

In other secondary outcomes, there was a significantly greater reduction in body weight at 32 weeks with CagriSema versus cagrilintide or semaglutide, with 71% of patients in the CagriSema group achieving greater than 10% reduction in body weight. Patients in the CagriSema group also had clinically relevant improvements in blood pressure, lipids, and high-sensitivity C-reactive protein.

Adverse events – reported in 68% of patients with CagriSema versus 71% with semaglutide and 80% with cagrilintide – were mostly mild or moderate gastrointestinal events, consistent with those seen in these two drug classes.

At week 32, time in range was 89% with CagriSema versus 76% with semaglutide and 72% with cagrilintide.

“Our phase 2 clinical trial is the first study to report efficacy and safety data for treatment with the combination of a GLP-1 agonist and an amylin analog in participants with type 2 diabetes,” the researchers summarize. “These data support further investigation of CagriSema in this population in longer and larger phase 3 studies.”

This trial was sponsored by Novo Nordisk. Dr. Frias, Dr. Mathieu, Dr. Apovian, and Dr. McDonnell reported financial relationships with a number of companies.

OASIS and PIONEER PLUS support high-dose oral semaglutide

Article Type

Tue, 06/27/2023 - 08:33

Higher doses of oral semaglutide than the 14-mg/day dose that is currently approved for type 2 diabetes may be additional options for patients with prediabetes or diabetes and obesity, according to the results of two new phase 3 clinical trials.

The two trials, OASIS in patients with overweight or obesity without diabetes and PIONEER PLUS in patients with inadequately controlled type 2 diabetes, were presented at the annual scientific sessions of the American Diabetes Association and simultaneously published in The Lancet.

Dr. Vanita R. Aroda

Filip K. Knop, MD, PhD, University of Copenhagen, presented highlights of the OASIS-1 results, and Vanita R. Aroda, MD, Brigham and Women’s Hospital and Harvard University, Boston, presented key findings of PIONEER PLUS, during a press briefing prior to the ADA session.

OASIS-1 showed that “oral semaglutide 50 mg may represent an effective option for the treatment of obesity, particularly in patients who prefer oral administration,” Dr. Knop summarized.

And “the PIONEER PLUS trial showed superior glycemic control and body-weight loss and improvement in cardiometabolic risk factors, with higher doses of once-daily oral semaglutide (25 mg and 50 mg) compared with the currently [highest] approved 14-mg dose,” said Dr. Aroda.

Session chair Marion Pragnell, PhD, vice president of research & science at ADA, said in an interview there is a need for multiple treatment options, as different patients respond differently to individual drugs. The oral dose of semaglutide has to be higher than that approved for subcutaneous injection (as Ozempic or Wegovy) because of bioavailability, but small-molecule research is advancing such that in future lower doses of oral drugs may have the same effect as the current lower subcutaneous doses of the drug.

The oral version of semaglutide (Rybelsus) was approved in the United States for type 2 diabetes in doses of 7 mg or 14 mg per day in 2019; it has not been approved for use in obesity.

Dr. Knop remarked that, in his clinical practice, about 25% of patients with type 2 diabetes prefer daily oral semaglutide and the rest prefer weekly injected semaglutide.

“Having an oral formulation of semaglutide in addition to the subcutaneous, or injectable, formula available will allow people who struggle to lose weight with diet and physical activity alone to take this effective medication in a way that best suits them,” he added.

Participants in OASIS and PIONEER PLUS were instructed to take the once-daily study drug tablet in the morning, in the fasting state, with up to half a glass of water (120 mL) at least 30 minutes before intake of any other food, beverage, or oral medication.
 

OASIS: 50-mg daily pill in adults with overweight or obesity

OASIS is, to their knowledge, “the first trial to assess the bodyweight-lowering effect of an oral GLP-1 agonist (semaglutide 50 mg taken once per day) in adults with overweight or obesity, without type 2 diabetes,” Dr. Knop and colleagues wrote.

The 50-mg dose induced clinically meaningful reductions in bodyweight, with accompanying improvements in cardiometabolic risk factors, consistent with results reported for subcutaneous semaglutide 2.4 mg once weekly (Wegovy) in a similar population.

As an adjunct to diet and physical activity, oral semaglutide 50 mg led to a mean bodyweight reduction of 15.1%, compared with 2.4% in the placebo group, and greater percentages of participants reaching bodyweight reduction targets of at least 5%, 10%, 15%, and 20%.

Body-weight reductions were accompanied by significant improvements in cardiometabolic risk factors, compared with placebo.

“These results indicate that oral semaglutide 50 mg could provide an effective, future option for people with overweight or obesity who would benefit from a GLP-1 receptor agonist,” they concluded.
 

 

 

PIONEER PLUS: Inadequately controlled type 2 diabetes

Reporting the PIONEER PLUS data, Dr. Aroda and colleagues said: “For people with inadequately controlled type 2 diabetes on a stable dose of one to three oral glucose-lowering drugs, higher doses (25 mg and 50 mg) of once-daily oral semaglutide provided more effective glycemic control and greater bodyweight loss than 14 mg semaglutide, without additional safety concerns.”

PIONEER PLUS is the first study to indicate that these bigger doses of semaglutide might provide a highly effective oral option to improve both glycemic control and weight loss in type 2 diabetes.

“This trial provides compelling evidence that the availability of a wider range of doses of oral semaglutide will allow for individualized dosing to the desired effect, and the ability to intensify treatment as needed,” said Dr. Aroda. “We are hopeful that these results encourage earlier effective management of type 2 diabetes and allow for broader management in the primary care setting.”

In an accompanying editorial Christina H. Sherrill, PharmD, and Andrew Y. Hwang, PharmD, write: “This expansion in dosing titration might provide clinicians with more opportunities to obtain the maximum efficacy of this oral GLP-1 agonist.”

But additional investigations “to establish whether the superior glycemic reduction seen at these higher doses translates into cardiovascular risk reduction” are needed, said Dr. Sherrill, of High Point (N.C.) University, and Dr. Hwang, of Massachusetts College of Pharmacy and Health Sciences University, Boston.

Such investigations “would further elucidate the place in therapy of high-dose oral semaglutide,” they concluded.

Dr. Aroda and colleagues agreed: “Future real-world studies will be needed to investigate the clinical impact of the availability of higher doses of oral semaglutide.”

The trials were funded by Novo Nordisk.

As an adjunct to diet and physical activity, oral semaglutide 50 mg led to a mean bodyweight reduction of 15.1%, compared with 2.4% in the placebo group, and greater percentages of participants reaching bodyweight reduction targets of at least 5%, 10%, 15%, and 20%.

Body-weight reductions were accompanied by significant improvements in cardiometabolic risk factors, compared with placebo.

“These results indicate that oral semaglutide 50 mg could provide an effective, future option for people with overweight or obesity who would benefit from a GLP-1 receptor agonist,” they concluded.
 

 

 

PIONEER PLUS: Inadequately controlled type 2 diabetes

Reporting the PIONEER PLUS data, Dr. Aroda and colleagues said: “For people with inadequately controlled type 2 diabetes on a stable dose of one to three oral glucose-lowering drugs, higher doses (25 mg and 50 mg) of once-daily oral semaglutide provided more effective glycemic control and greater bodyweight loss than 14 mg semaglutide, without additional safety concerns.”

PIONEER PLUS is the first study to indicate that these bigger doses of semaglutide might provide a highly effective oral option to improve both glycemic control and weight loss in type 2 diabetes.

“This trial provides compelling evidence that the availability of a wider range of doses of oral semaglutide will allow for individualized dosing to the desired effect, and the ability to intensify treatment as needed,” said Dr. Aroda. “We are hopeful that these results encourage earlier effective management of type 2 diabetes and allow for broader management in the primary care setting.”

In an accompanying editorial Christina H. Sherrill, PharmD, and Andrew Y. Hwang, PharmD, write: “This expansion in dosing titration might provide clinicians with more opportunities to obtain the maximum efficacy of this oral GLP-1 agonist.”

But additional investigations “to establish whether the superior glycemic reduction seen at these higher doses translates into cardiovascular risk reduction” are needed, said Dr. Sherrill, of High Point (N.C.) University, and Dr. Hwang, of Massachusetts College of Pharmacy and Health Sciences University, Boston.

Such investigations “would further elucidate the place in therapy of high-dose oral semaglutide,” they concluded.

Dr. Aroda and colleagues agreed: “Future real-world studies will be needed to investigate the clinical impact of the availability of higher doses of oral semaglutide.”

The trials were funded by Novo Nordisk.

Higher doses of oral semaglutide than the 14-mg/day dose that is currently approved for type 2 diabetes may be additional options for patients with prediabetes or diabetes and obesity, according to the results of two new phase 3 clinical trials.

The two trials, OASIS in patients with overweight or obesity without diabetes and PIONEER PLUS in patients with inadequately controlled type 2 diabetes, were presented at the annual scientific sessions of the American Diabetes Association and simultaneously published in The Lancet.

Dr. Vanita R. Aroda

Filip K. Knop, MD, PhD, University of Copenhagen, presented highlights of the OASIS-1 results, and Vanita R. Aroda, MD, Brigham and Women’s Hospital and Harvard University, Boston, presented key findings of PIONEER PLUS, during a press briefing prior to the ADA session.

OASIS-1 showed that “oral semaglutide 50 mg may represent an effective option for the treatment of obesity, particularly in patients who prefer oral administration,” Dr. Knop summarized.

And “the PIONEER PLUS trial showed superior glycemic control and body-weight loss and improvement in cardiometabolic risk factors, with higher doses of once-daily oral semaglutide (25 mg and 50 mg) compared with the currently [highest] approved 14-mg dose,” said Dr. Aroda.

Session chair Marion Pragnell, PhD, vice president of research & science at ADA, said in an interview there is a need for multiple treatment options, as different patients respond differently to individual drugs. The oral dose of semaglutide has to be higher than that approved for subcutaneous injection (as Ozempic or Wegovy) because of bioavailability, but small-molecule research is advancing such that in future lower doses of oral drugs may have the same effect as the current lower subcutaneous doses of the drug.

The oral version of semaglutide (Rybelsus) was approved in the United States for type 2 diabetes in doses of 7 mg or 14 mg per day in 2019; it has not been approved for use in obesity.

Dr. Knop remarked that, in his clinical practice, about 25% of patients with type 2 diabetes prefer daily oral semaglutide and the rest prefer weekly injected semaglutide.

“Having an oral formulation of semaglutide in addition to the subcutaneous, or injectable, formula available will allow people who struggle to lose weight with diet and physical activity alone to take this effective medication in a way that best suits them,” he added.

Participants in OASIS and PIONEER PLUS were instructed to take the once-daily study drug tablet in the morning, in the fasting state, with up to half a glass of water (120 mL) at least 30 minutes before intake of any other food, beverage, or oral medication.
 

OASIS: 50-mg daily pill in adults with overweight or obesity

OASIS is, to their knowledge, “the first trial to assess the bodyweight-lowering effect of an oral GLP-1 agonist (semaglutide 50 mg taken once per day) in adults with overweight or obesity, without type 2 diabetes,” Dr. Knop and colleagues wrote.

Tackle education and mindset to reduce diabetes distress

Article Type

Interventions that specifically address diabetes distress can not only improve patient mental health but can also cut costs, according to two new studies in patients with type 1 diabetes presented at the annual scientific sessions of the American Diabetes Association.

Danielle Hessler Jones, PhD, presented findings from Behavioral Approaches to Reducing Diabetes Distress and Improving Glycemic Control (EMBARK) in adults with type 1 diabetes during an oral session.

The three-arm randomized trial found that patients had the greatest improvements in feelings of powerlessness after a 3-month behavioral intervention that combined type 1 diabetes education plus specific attention to diabetes distress.

And in a late-breaking poster, “Do The Right Thing: Behavioral Intervention for At-Risk T1D Youth,” David V. Wagner, PhD, showed that a behavioral intervention not only improved glycemic management but also reduced cost of care in disadvantaged youth.

“Diabetes distress is the emotional response to living with diabetes, the burden of relentless daily self-management, and the prospect of its long-term complications,” said Dr. Hessler Jones, professor and vice chair for research in the department of family and community medicine at the University of California, San Francisco.  

It is common, experienced by 20%-58% of people with type 1 and type 2 diabetes, and is different from depression, as it is associated with glycemic control and disease management. It “is also chronic and does not disappear on its own without intervention,” she stressed.

“It is the expected worries, concerns, and fears that are associated with struggling with a demanding and progressive chronic disease and its management,” she added.

The findings from EMBARK “suggest that distress reductions are greatest when interventions integrate education alongside approaches to address the emotional side of diabetes,” she said.  

The group is also analyzing changes in A1c with the three different interventions in EMBARK, with results expected this fall.

Dr. Hessler Jones said they also just received funding for DDASSIST, which will answer the question: “How do I translate this into care in my clinic?” The aim of the clinic training program is to bring the intervention to the diabetes care team.

“Could this program be delivered by somebody else, other than a psychologist?” an audience member asked. They will be looking at this, she replied.
 

‘Do the right thing’

For the late-breaking poster by Dr. Wagner and colleagues, researchers evaluated direct cost data from three health care systems provided for youth with type 1 diabetes who received an intensive behavioral health intervention, Novel Interventions in Children’s Healthcare (NICH).

Youths were included in the analyses if they had type 1 diabetes and at least 1 year of cost data prior to and following NICH enrollment. Outpatient, emergency department, and inpatient costs were combined. The analysis included 53 youth with the following characteristics: mean age, 14.2 years; 87% Medicaid; 58% female; 32% Black, 29% Non-Hispanic White, 28% Hispanic/Latinx, 7% Pacific Islander, 2% Asian, and 2% other racial and ethnic groups.

Average yearly costs significantly decreased from $20,400 per youth prior to NICH to $9,500 per youth afterward, largely due to inpatient charges.

“These results highlight the benefits of providing access to intensive interventions to pediatric populations experiencing health disparities,” said Dr. Wagner. “Investing early in the lives of youth experiencing health disparities is not only the right thing to do to improve patients’ health but it could also have a positive economic impact down the road.”
 

 

 

Three interventions in 300 adults with type 1 diabetes

Meanwhile, EMBARK recruited 300 patients with type 1 diabetes in the United States from clinics and community organizations who were aged 21 and older and had an elevated type 1 diabetes distress score (> 2.0) and A1c greater than or equal to 7.5%.

Participants were a mean age of 46 years, 79% were female, and 89% were White. They had a type 1 diabetes distress score of 2.8, a mean A1c of 8.3%, and 71% used an insulin pump and 79% used a continuous glucose monitor.

Participants were randomized to one of three interventions:

  • Streamline: A traditional diabetes educator-led education and management program.
  • Tuned-in: A psychologist-led program focused exclusively on reducing diabetes distress.
  • Fixit: An integration of the two programs.

Interventions were given virtually over 3 months to small groups of 8-12 individuals and included initial workshops, one-to-one phone calls, and follow-up group meetings. Participants were then followed for 8 months.  

Researchers found statistically significant and substantial reductions in overall diabetes distress in all three interventions, with the greatest reductions in the combined intervention group, which were greater than in the educational approach alone group (P = .005).

The percentage of participants who no longer reported elevated diabetes distress at follow-up was 25% in Streamline, 37% in Tuned-in, and 42% in Fixit.

The percentage of participants who reported a minimal clinically important difference – the smallest change in a treatment outcome that an individual would identify as important – was also greatest in those in the Fixit intervention group (82%) than in the Tuned-in (74%) or Streamline (65%) interventions.
 

‘Adding the psychologist is where the real magic happens’

“The certified diabetes care specialist intervention is really a very standard thing that most clinicians would have access to; they tend to focus on knowledge and problem solving and some of the psychosocial issues,” Robert Gabbay, MD, PhD, chief scientific and medical officer for the ADA, said in an interview.

The EMBARK trial found a “graded response: CDCS alone, psychologist really focused on diabetes distress, and the two together, which would be the ideal practice model,” he noted.

There are these validated ways of measuring diabetes distress using a diabetes distress survey tool, which is also underutilized.  

“Adding the psychologist is really where the real magic happens in terms of diabetes distress,” Dr. Gabbay said.

“As you can imagine, [if] somebody ... feels powerless, it is going to be tough to manage their diabetes and unlikely to be terribly successful,” he observed. Often, these individuals are just not doing well. This study highlighted the importance of identifying this.

“I’m encouraged by the findings from the studies presented during this year’s Scientific Sessions as we continue to seek out innovative, evidence-based solutions that support people living with diabetes when they need it the most,” Dr. Gabbay concluded.

‘Striking’ benefit of lipid lowering in primary prevention

Article Type
Changed
Tue, 06/27/2023 - 09:30

A new analysis of a large-scale trial of a novel lipid-lowering agent has shown a particularly large reduction in cardiovascular events in the primary prevention population enrolled in the study, two-thirds of whom also had type 2 diabetes, leading to calls for more attention to be paid to this group of patients.

The main results of the CLEAR Outcomes trial of bempedoic acid (Nexletol, Esperion) in a mixed secondary and primary prevention population intolerant to statins, presented in March at the 2023 joint scientific sessions of the American College of Cardiology and the World Heart Federation, showed a 13% relative risk reduction in the main primary endpoint, a composite of cardiovascular death, myocardial infarction, stroke, or coronary revascularization.

This new analysis of the 4,206 high-risk primary prevention patients in the study – 67% of whom also had type 2 diabetes – has shown a 30% relative risk reduction in the same endpoint.

Other key endpoints were reduced to a similar or even greater extent, with the composite of cardiovascular death/stroke/MI showing a 36% relative risk reduction, and a 39% relative risk reduction for cardiovascular death and MI individually.

Dr. Steven Nissen

“These results are frankly striking,” lead investigator Steve Nissen, MD, said in an interview. 

“These are really large reductions. These results are telling us that high-risk primary prevention patients, although their absolute event rate is lower than secondary prevention patients, can have very impressive relative risk reductions in major cardiovascular events with lipid-lowering therapy,” he said.

But Dr. Nissen, chief academic officer at the Heart Vascular & Thoracic Institute at the Cleveland Clinic, pointed out that this population of patients is not well treated. 

“This is the problem: Less than half of high-risk primary prevention patients in the U.S., and in virtually every other developed country, are receiving cholesterol-lowering medication. These patients tend to get ignored,” he stressed. 

Asked what advice he would give to clinicians based on the current findings, Dr. Nissen said: “If a patient is at high risk of developing cardiovascular disease, particularly those with [type 2] diabetes, they need to go on a lipid-lowering drug.” 

“If patients can tolerate a statin then that should be the first choice. We know statins work, and they are now inexpensive. They are likely to give the exact same benefit as we have shown in this study with bempedoic acid, as the two drug classes work by very similar mechanisms. But if patients can’t tolerate a statin, then treat them with bempedoic acid. The bottom line is that these patients just need to be treated,” he said.
 

‘Wake-up call’

He said these new results are a “wake-up call for the medical community that we need to pay far more attention to high-risk primary prevention patients.”

Dr. Nissen does not believe the effect is specific to bempedoic acid; rather, it is more likely an effect of lowering LDL cholesterol (LDL-C) levels. 

“This message is not about bempedoic acid, in particular. We have seen similar findings in historical studies with the statins, but that seems to have been forgotten. The message is about lowering LDL in patients who are at high risk of having a first cardiovascular event. We need to identify patients at high risk for a first cardiac event and get them on a cholesterol-lowering drug – and in most cases that will be a statin.”

Dr. Nissen presented the new analysis from the CLEAR OUTCOMES trial at the annual scientific sessions of the American Diabetes Association. It was simultaneously published online in JAMA.

He pointed out that large trials of lipid-lowering therapy in the primary prevention population have not been done for many years. 

“All the contemporary trials with lipid-lowering therapy have only included secondary prevention patients and they often enroll patients after an acute coronary syndrome event.

“But for the CLEAR OUTCOMES trial, we included a significant amount of primary prevention patients – those with risk factors such as [type 2] diabetes and hypertension who are considered to be at high risk of developing cardiovascular disease,” he explained.

CLEAR OUTCOMES was a masked, randomized, trial that enrolled 13,970 statin-intolerant patients. The new analysis included 4,206 of those patients with risk factors for heart disease but without a prior cardiovascular event – the primary prevention group. The mean age of these participants was 68 years, 67% had diabetes, and 59% were women.

Treatment with bempedoic acid showed a 22% reduction in LDL-C, compared with placebo, with a reduction of 30.2 mg/dL from a mean baseline of 142.5 mg/dL. High-sensitivity C-reactive protein (CRP) levels were also reduced by 0.56 mg/L (21.5%), from a median baseline of 2.4 mg/L.

Dr. Nissen told a press briefing at the ADA meeting that he believes “it’s the combination of LDL lowering and reduction in CRP that might have been the driver [for the effects we saw in the trial]. Certainly, bempedoic acid lowers both.”

And he noted the recent U.S. approval of a new low dose of colchicine 0.5 mg (Lodoco, Agepha Pharma) with a broad indication for use in atherosclerotic cardiovascular disease (ASCVD), which represents a completely new approach to treatment, specifically targeting inflammation as a driver of atherosclerosis.

Bempedoic acid is a prodrug that works along the same pathways as statins but does not cause muscle pain, which makes many people intolerant to statins. Bempedoic acid was first approved by the Food and Drug Administration in 2020 for the treatment of adults with heterozygous familial hypercholesterolemia or established ASCVD who require additional LDL-C lowering.
 

 

 

Greater benefit in primary prevention?

In this primary prevention group, treatment with bempedoic acid for 40 months was associated with a significant risk reduction for the primary endpoint – a composite of cardiovascular death, nonfatal MI, nonfatal stroke, or coronary revascularization – which occurred in 5.3% of the treatment group versus 7.6% in the placebo group (adjusted hazard ratio, 0.70; P = .002). This represents a 30% relative risk reduction in major cardiovascular events.

Other key secondary endpoints also showed impressive reductions.

The rate of the composite endpoint of cardiovascular death, MI, or stroke was 6.4% in the placebo group and 4.0% with bempedoic acid (HR, 0.64; P < .001); MI occurred in 2.2% versus 1.4% (HR, 0.61), cardiovascular death in 3.1% versus 1.8% (HR, 0.61), and all-cause mortality in 5.2% versus 3.6% (HR, 0.73), respectively.

Adverse effects with bempedoic acid included a higher incidence of gout (2.6% vs 2.0%), cholelithiasis (2.5% vs. 1.1%), and increases in serum creatinine, uric acid, and hepatic enzyme levels.

Dr. Nissen believed these results suggest that there may be a greater benefit of lipid lowering in high-risk primary prevention patients than in the secondary prevention population.

“It may seem paradoxical, but there is actually some history that this may be the case,” he said.

He pointed out that the JUPITER trial of rosuvastatin in 2008 was the last major primary prevention trial of a lipid-lowering agent, which was stopped early with a 44% reduction of the primary endpoint.

He noted that one of the arguments against the use of statins in primary prevention is the belief that absolute risk reductions are quite modest.

“But in this analysis, we found an absolute risk reduction of 2.3% for the primary endpoint. That’s a number needed to treat to prevent 1 event of 43. That’s pretty good,” he said.

Trying to explain why there may be more benefit in the primary prevention population, Dr. Nissen suggested that these patients may have more vulnerable plaques.

“I think high-risk primary prevention patients probably have a lot of lipid-laden plaque – some people call it ‘vulnerable’ plaque. These are softer, cholesterol-laden plaque. We know that treatment with cholesterol-lowering medication causes these plaques to shrink. The lipid core is delipidated and the plaque stabilizes,” he explained. “It may be that in secondary prevention patients to some extent the horse is already out of the barn – they have advanced disease. But primary prevention patients may have plaques that are more amenable to modification by cholesterol lowering.”

He admitted that the idea is only speculation. “But that is a potential explanation for our observations.”
 

Editorial cautious

In an accompanying editorial, also published in JAMA, Dhruv S. Kazi, MD, Beth Israel Deaconess Medical Center, Boston, said the findings need to be interpreted with caution as they come from one of many subgroup analyses of a larger trial.

Dr. Kazi pointed out that the intervention and control survival curves separate right away, on the first day of follow-up, whereas the true effect of lipid-lowering therapy for primary prevention would be expected to have a somewhat delayed onset, an observation he says supports the argument that this is a chance finding.

Dr. Kazi also reminded clinicians that bempedoic acid should not be regarded as a substitute for statins, which should remain the first-line therapy for primary prevention.

“For now, available evidence suggests that, although bempedoic acid is not a perfect substitute for a statin, it is a reasonable therapeutic choice for primary prevention of ASCVD events in high-risk, statin-intolerant patients,” he concluded.

A new analysis of a large-scale trial of a novel lipid-lowering agent has shown a particularly large reduction in cardiovascular events in the primary prevention population enrolled in the study, two-thirds of whom also had type 2 diabetes, leading to calls for more attention to be paid to this group of patients.

The main results of the CLEAR Outcomes trial of bempedoic acid (Nexletol, Esperion) in a mixed secondary and primary prevention population intolerant to statins, presented in March at the 2023 joint scientific sessions of the American College of Cardiology and the World Heart Federation, showed a 13% relative risk reduction in the main primary endpoint, a composite of cardiovascular death, myocardial infarction, stroke, or coronary revascularization.

This new analysis of the 4,206 high-risk primary prevention patients in the study – 67% of whom also had type 2 diabetes – has shown a 30% relative risk reduction in the same endpoint.

Other key endpoints were reduced to a similar or even greater extent, with the composite of cardiovascular death/stroke/MI showing a 36% relative risk reduction, and a 39% relative risk reduction for cardiovascular death and MI individually.

Dr. Steven Nissen

“These results are frankly striking,” lead investigator Steve Nissen, MD, said in an interview. 

“These are really large reductions. These results are telling us that high-risk primary prevention patients, although their absolute event rate is lower than secondary prevention patients, can have very impressive relative risk reductions in major cardiovascular events with lipid-lowering therapy,” he said.

But Dr. Nissen, chief academic officer at the Heart Vascular & Thoracic Institute at the Cleveland Clinic, pointed out that this population of patients is not well treated. 

“This is the problem: Less than half of high-risk primary prevention patients in the U.S., and in virtually every other developed country, are receiving cholesterol-lowering medication. These patients tend to get ignored,” he stressed. 

Asked what advice he would give to clinicians based on the current findings, Dr. Nissen said: “If a patient is at high risk of developing cardiovascular disease, particularly those with [type 2] diabetes, they need to go on a lipid-lowering drug.” 

“If patients can tolerate a statin then that should be the first choice. We know statins work, and they are now inexpensive. They are likely to give the exact same benefit as we have shown in this study with bempedoic acid, as the two drug classes work by very similar mechanisms. But if patients can’t tolerate a statin, then treat them with bempedoic acid. The bottom line is that these patients just need to be treated,” he said.
 

‘Wake-up call’

He said these new results are a “wake-up call for the medical community that we need to pay far more attention to high-risk primary prevention patients.”

Dr. Nissen does not believe the effect is specific to bempedoic acid; rather, it is more likely an effect of lowering LDL cholesterol (LDL-C) levels. 

“This message is not about bempedoic acid, in particular. We have seen similar findings in historical studies with the statins, but that seems to have been forgotten. The message is about lowering LDL in patients who are at high risk of having a first cardiovascular event. We need to identify patients at high risk for a first cardiac event and get them on a cholesterol-lowering drug – and in most cases that will be a statin.”

Dr. Nissen presented the new analysis from the CLEAR OUTCOMES trial at the annual scientific sessions of the American Diabetes Association. It was simultaneously published online in JAMA.

He pointed out that large trials of lipid-lowering therapy in the primary prevention population have not been done for many years. 

“All the contemporary trials with lipid-lowering therapy have only included secondary prevention patients and they often enroll patients after an acute coronary syndrome event.

“But for the CLEAR OUTCOMES trial, we included a significant amount of primary prevention patients – those with risk factors such as [type 2] diabetes and hypertension who are considered to be at high risk of developing cardiovascular disease,” he explained.

CLEAR OUTCOMES was a masked, randomized, trial that enrolled 13,970 statin-intolerant patients. The new analysis included 4,206 of those patients with risk factors for heart disease but without a prior cardiovascular event – the primary prevention group. The mean age of these participants was 68 years, 67% had diabetes, and 59% were women.

Treatment with bempedoic acid showed a 22% reduction in LDL-C, compared with placebo, with a reduction of 30.2 mg/dL from a mean baseline of 142.5 mg/dL. High-sensitivity C-reactive protein (CRP) levels were also reduced by 0.56 mg/L (21.5%), from a median baseline of 2.4 mg/L.

SURMOUNT-2: Tirzepatide rings up major weight loss in type 2 diabetes

Article Type
Changed
Tue, 06/27/2023 - 08:35

Weekly tirzepatide injections in adults with type 2 diabetes and overweight or obesity safely led to 12.8%-14.7% in-trial weight loss after 72 weeks in the SURMOUNT-2 pivotal trial, a finding that will likely lead to Food and Drug Administration approval of a new indication for weight loss for tirzepatide.

Tirzepatide received FDA approval as a treatment for type 2 diabetes in adults, marketed as Mounjaro, in 2022. The agent – a “twincretin” that acts as an agonist at both the glucagon-like peptide-1 (GLP-1) receptor and glucose-dependent insulinotropic polypeptide (GIP) receptor – had also previously scored a decisive win for weight loss in adults with overweight or obesity without diabetes in the SURMOUNT-1 pivotal trial.

Taken together, results from SURMOUNT-1 and SURMOUNT-2 appear to make a good case for a weight-loss indication that will not depend on whether a patient also has type 2 diabetes.

“We anticipate that tirzepatide will be [FDA] approved for weight loss later this year,” W. Timothy Garvey, MD, lead researcher for SURMOUNT-2, said during a press briefing at the annual scientific sessions of the American Diabetes Association.
 

Tirzepatide ‘fills the gap’

Tirzepatide “fills the gap to get [medication-driven] weight loss in the range of 15% of baseline weight or better,” Dr. Garvey noted, which puts it in a favorable position relative to a 2.4-mg weekly subcutaneous injection with the GLP-1 agonist semaglutide (Wegovy), which produced an average weight loss from baseline of about 9.6% in people with type 2 diabetes in the STEP-2 trial

Dr. W. Timothy Garvey

Although tirzepatide has not been compared head-to-head for weight loss with any of the several available GLP-1 agonists, the reported weight-loss numbers seem to favor tirzepatide, said Dr. Garvey, director of the Diabetes Research Center of the University of Alabama at Birmingham.

“If you look at the degree of weight loss across trials, we see a clinically significant difference in weight loss” compared with semaglutide and other agents that only act on the GLP-1 receptor, he noted. (Although cross-trial comparisons of different medications often have uncertain reliability.)

“The data suggest an incremental effect from tirzepatide” compared with the GLP-1 agonists now approved for weight loss, said Marlon Pragnell, PhD, vice president, research and science, ADA, who was not involved in the tirzepatide studies.

This is a “step forward for treating people with obesity and type 2 diabetes; it’s a very promising treatment option,” Dr. Pragnell said in an interview.
 

Tirzepatide the ‘most effective agent’

Ildiko Lingvay, MD, the designated discussant for the SURMOUNT-2 presentation at the meeting, fully agreed. The new findings “confirm that tirzepatide is the most effective agent currently on the [U.S.] market to help achieve the two coprimary goals for patients with type 2 diabetes – weight loss and glycemic control – while also having favorable effects on cardiovascular risk factors,” said Dr. Lingvay, an endocrinologist at UT Southwestern Medical Center in Dallas, who was not involved with the SURMOUNT studies.

Dr. Ildiko Lingvay

Dr. Lingvay offered as evidence the performance of tirzepatide’s main rival for weight loss semaglutide (Wegovy), delivered at the 2.4 mg/week subcutaneous injected dosage approved for weight loss. The semaglutide trial that SURMOUNT-2 most resembles is the STEP-2 trial, she said, which showed as its primary outcome a 9.6% average weight loss from baseline after 68 weeks of weekly semaglutide that compares, in a cross-trial way, with the 14.7% average drop from baseline weight with 15 mg tirzepatide weekly for 72 weeks and an average 12.8% weight loss with a weekly 10-mg tirzepatide dose.

“It’s fair to say that tirzepatide has an edge,” despite the limitations of cross-trial comparisons, Dr. Lingvay said in an interview.

But she acknowledged that superior weight loss efficacy takes a back seat in U.S. practice to access and affordability when making a prescribing decision for individual patients as these newer drugs are all expensive. 
 

Affordability and access will remain a ‘big problem’

Dr. Garvey, too, cautioned that access and affordability of tirzepatide as well as other GLP-1 agonists remains a major sticking point.

“These medications are very expensive – more than $1,000 a dose – and this cost limits access ... [which is] a big problem,” Dr. Garvey noted. U.S. health care payers “do not want to open the gates [to expensive treatments] for a disorder that’s as common as obesity.”

“Access and affordability are always an issue for these medications,” agreed Janet Brown-Friday, RN, president, health care and education, ADA, who had no role in the tirzepatide studies.

SURMOUNT-2 randomized 938 adults with type 2 diabetes and overweight or obesity at 77 centers in seven countries including the United States from March 2021 to April 2023. The study had two primary outcomes: Average percent change in body weight from baseline to week 72, and percentage of participants who achieved a weight reduction from baseline of at least 5% after 72 weeks.
 

In-trial weight loss of 12.8%-14.7%

The in-trial analysis showed that a 10-mg weekly subcutaneous dose of tirzepatide resulted in an average 12.8% weight loss from baseline, and a 15-mg weekly subcutaneous dose led to an average 14.7% drop from baseline weight. People randomized to receive a placebo injection averaged a 3.2% drop from their baseline weight after 72 weeks, a finding that documents significant improvements compared with placebo with both tirzepatide doses.

The percentage of patients who achieved at least a 5% reduction in weight from baseline was 79% with the 10-mg dose of tirzepatide, 83% with the 15-mg dose, and 32% with placebo; these improvements were significant for both tirzepatide doses compared with placebo.

A 15% or greater reduction in weight from baseline occurred in 40%-48% of people who received tirzepatide compared with 3% of those who received placebo. A reduction in weight of this magnitude from baseline “will prevent a broad array of complications,” Dr. Garvey noted.

The results were simulatenously published online in The Lancet.
 

Glucose control without severe hypoglycemia

The safety profile of tirzepatide in SURMOUNT-2 was consistent with prior studies of the agent, as well as with other medications in the GLP-1 agonist class, with gastrointestinal adverse effects such as nausea and vomiting predominating, especially during the dose-escalation phase at treatment onset.

Dr. Garvey especially highlighted the overall safety of tirzepatide, and particularly its ability to produce clinically important reductions in A1c that averaged more than two percentage points from baseline values without producing a single episode of severe hypoglycemia, and an incidence of milder hypoglycemia of less than a 5%.

The absence of any severe hypoglycemia was “amazing,” Dr. Garvey said, especially given that 46%-49% of people taking tirzepatide in SURMOUNT-2 achieved normalization of their A1c to less than 5.7% on treatment compared with 4% of participants taking placebo.

The results also showed the benefit of a “big reduction in fasting insulin levels,” which averaged a 41% cut from baseline in those who received the 15-mg subcutaneous weekly dose of tirzepatide, coupled with increased insulin sensitivity, Dr. Garvey said.

Dr. Garvey disclosed ties to Eli Lilly, which sponsored SURMOUNT-2 and markets tirzepatide (Mounjaro), as well Boehringer Ingelheim, Novo Nordisk, Pfizer, Fractyl Health, Alnylam Pharmaceuticals, Inogen, and Merck. He has been an investigator for studies sponsored by Novo Nordisk, Epitomee, Neurovalens, and Pfizer. Dr. Pragnell and Dr. Brown-Friday have disclosed no relevant financial relationships.

“We anticipate that tirzepatide will be [FDA] approved for weight loss later this year,” W. Timothy Garvey, MD, lead researcher for SURMOUNT-2, said during a press briefing at the annual scientific sessions of the American Diabetes Association.
 

Tirzepatide ‘fills the gap’

Tirzepatide “fills the gap to get [medication-driven] weight loss in the range of 15% of baseline weight or better,” Dr. Garvey noted, which puts it in a favorable position relative to a 2.4-mg weekly subcutaneous injection with the GLP-1 agonist semaglutide (Wegovy), which produced an average weight loss from baseline of about 9.6% in people with type 2 diabetes in the STEP-2 trial

Although tirzepatide has not been compared head-to-head for weight loss with any of the several available GLP-1 agonists, the reported weight-loss numbers seem to favor tirzepatide, said Dr. Garvey, director of the Diabetes Research Center of the University of Alabama at Birmingham.

“If you look at the degree of weight loss across trials, we see a clinically significant difference in weight loss” compared with semaglutide and other agents that only act on the GLP-1 receptor, he noted. (Although cross-trial comparisons of different medications often have uncertain reliability.)

“The data suggest an incremental effect from tirzepatide” compared with the GLP-1 agonists now approved for weight loss, said Marlon Pragnell, PhD, vice president, research and science, ADA, who was not involved in the tirzepatide studies.

This is a “step forward for treating people with obesity and type 2 diabetes; it’s a very promising treatment option,” Dr. Pragnell said in an interview.
 

Tirzepatide the ‘most effective agent’

Ildiko Lingvay, MD, the designated discussant for the SURMOUNT-2 presentation at the meeting, fully agreed. The new findings “confirm that tirzepatide is the most effective agent currently on the [U.S.] market to help achieve the two coprimary goals for patients with type 2 diabetes – weight loss and glycemic control – while also having favorable effects on cardiovascular risk factors,” said Dr. Lingvay, an endocrinologist at UT Southwestern Medical Center in Dallas, who was not involved with the SURMOUNT studies.

Dr. Lingvay offered as evidence the performance of tirzepatide’s main rival for weight loss semaglutide (Wegovy), delivered at the 2.4 mg/week subcutaneous injected dosage approved for weight loss. The semaglutide trial that SURMOUNT-2 most resembles is the STEP-2 trial, she said, which showed as its primary outcome a 9.6% average weight loss from baseline after 68 weeks of weekly semaglutide that compares, in a cross-trial way, with the 14.7% average drop from baseline weight with 15 mg tirzepatide weekly for 72 weeks and an average 12.8% weight loss with a weekly 10-mg tirzepatide dose.

“It’s fair to say that tirzepatide has an edge,” despite the limitations of cross-trial comparisons, Dr. Lingvay said in an interview.

But she acknowledged that superior weight loss efficacy takes a back seat in U.S. practice to access and affordability when making a prescribing decision for individual patients as these newer drugs are all expensive. 
 

Affordability and access will remain a ‘big problem’

Dr. Garvey, too, cautioned that access and affordability of tirzepatide as well as other GLP-1 agonists remains a major sticking point.

“These medications are very expensive – more than $1,000 a dose – and this cost limits access ... [which is] a big problem,” Dr. Garvey noted. U.S. health care payers “do not want to open the gates [to expensive treatments] for a disorder that’s as common as obesity.”

“Access and affordability are always an issue for these medications,” agreed Janet Brown-Friday, RN, president, health care and education, ADA, who had no role in the tirzepatide studies.

SURMOUNT-2 randomized 938 adults with type 2 diabetes and overweight or obesity at 77 centers in seven countries including the United States from March 2021 to April 2023. The study had two primary outcomes: Average percent change in body weight from baseline to week 72, and percentage of participants who achieved a weight reduction from baseline of at least 5% after 72 weeks.
 

In-trial weight loss of 12.8%-14.7%

The in-trial analysis showed that a 10-mg weekly subcutaneous dose of tirzepatide resulted in an average 12.8% weight loss from baseline, and a 15-mg weekly subcutaneous dose led to an average 14.7% drop from baseline weight. People randomized to receive a placebo injection averaged a 3.2% drop from their baseline weight after 72 weeks, a finding that documents significant improvements compared with placebo with both tirzepatide doses.

The percentage of patients who achieved at least a 5% reduction in weight from baseline was 79% with the 10-mg dose of tirzepatide, 83% with the 15-mg dose, and 32% with placebo; these improvements were significant for both tirzepatide doses compared with placebo.

A 15% or greater reduction in weight from baseline occurred in 40%-48% of people who received tirzepatide compared with 3% of those who received placebo. A reduction in weight of this magnitude from baseline “will prevent a broad array of complications,” Dr. Garvey noted.

The results were simulatenously published online in The Lancet.
 

Glucose control without severe hypoglycemia

The safety profile of tirzepatide in SURMOUNT-2 was consistent with prior studies of the agent, as well as with other medications in the GLP-1 agonist class, with gastrointestinal adverse effects such as nausea and vomiting predominating, especially during the dose-escalation phase at treatment onset.

Dr. Garvey especially highlighted the overall safety of tirzepatide, and particularly its ability to produce clinically important reductions in A1c that averaged more than two percentage points from baseline values without producing a single episode of severe hypoglycemia, and an incidence of milder hypoglycemia of less than a 5%.

The absence of any severe hypoglycemia was “amazing,” Dr. Garvey said, especially given that 46%-49% of people taking tirzepatide in SURMOUNT-2 achieved normalization of their A1c to less than 5.7% on treatment compared with 4% of participants taking placebo.

The results also showed the benefit of a “big reduction in fasting insulin levels,” which averaged a 41% cut from baseline in those who received the 15-mg subcutaneous weekly dose of tirzepatide, coupled with increased insulin sensitivity, Dr. Garvey said.

Dr. Garvey disclosed ties to Eli Lilly, which sponsored SURMOUNT-2 and markets tirzepatide (Mounjaro), as well Boehringer Ingelheim, Novo Nordisk, Pfizer, Fractyl Health, Alnylam Pharmaceuticals, Inogen, and Merck. He has been an investigator for studies sponsored by Novo Nordisk, Epitomee, Neurovalens, and Pfizer. Dr. Pragnell and Dr. Brown-Friday have disclosed no relevant financial relationships.

Weekly tirzepatide injections in adults with type 2 diabetes and overweight or obesity safely led to 12.8%-14.7% in-trial weight loss after 72 weeks in the SURMOUNT-2 pivotal trial, a finding that will likely lead to Food and Drug Administration approval of a new indication for weight loss for tirzepatide.

Tirzepatide received FDA approval as a treatment for type 2 diabetes in adults, marketed as Mounjaro, in 2022. The agent – a “twincretin” that acts as an agonist at both the glucagon-like peptide-1 (GLP-1) receptor and glucose-dependent insulinotropic polypeptide (GIP) receptor – had also previously scored a decisive win for weight loss in adults with overweight or obesity without diabetes in the SURMOUNT-1 pivotal trial.
