SAN DIEGO – 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.

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.

SAN DIEGO – 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.

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.

Eight-hour intermittent fasting had similar weight loss results to calorie counting in adults with obesity, a new study published online in Annals of Internal Medicine has found. The small, unblinded study compared weight loss in 77 participants who either intermittently fasted, adhered to a calorie-restricted diet, or were in a control group with no eating restrictions.

Compared with the control group, absolute weight loss for people in the intermittent fasting group was about 4.6 kg (10 lb), compared with 5.4 kg (12 lb) for those in the calorie-restriction group, after 12 months, with no significant difference between the intervention groups.

Intermittent fasting, or time-restricted eating, relies on the idea that the time you eat is more important for weight loss than what or how much you eat. The term is a catch-all for eating patterns that could include several full days of fasting per week or time-restricted eating during the day.

The effect of having less time to eat is thought to lead to the consumption of fewer calories, thought to be the main reason the approach works. Indeed, this trial found the intermittent fasting group ate 425 fewer calories per day, compared with 405 fewer calories per day in the calorie-restricted group. 

“Time-restricted eating is undoubtedly an attractive approach to weight loss in that it does not require the purchase of expensive food products, allows persons to continue consuming familiar foods, and omits complicated calorie tracking,” Shuhao Lin, RD, University of Illinois at Chicago, and colleagues write.

During the trial, participants were in a weight-loss phase for 6 months. The intermittent fasting group could eat anything they wanted to between 12 p.m. and 8 p.m., and didn’t have to count calories. The later time window is on par with the eating pattern of most people in the United States who fast.

The calorie-restriction group had to cut 25% of their daily calorie intake based on their total energy expenditure. They were also told to fill half of every plate with fruits or vegetables, and consume about half their energy as carbohydrates, 30% as fat, and 20% as protein.

The weight-loss phase was followed by a 6-month weight-maintenance phase. During this phase, the window for eating was extended from 10 a.m. to 8 p.m. for the intermittent fasting group, and the calorie-restriction group was told to match their energy needs, which overall, had reduced by about 15%, compared with baseline.

Most participants were women with a mean body weight of about 100 kg (220 pounds) at baseline.

Both the time-restricted eating and calorie-restriction groups regularly met with dietitians, which the authors of an accompanying editorial say could have made the intermittent fasting more effective than in previous trials.

An earlier, shorter trial found about 0.9 kg (2 lb) weight loss after 12 weeks of adhering to a similar eating window, a more modest result, compared with the 4 kg (9 lb) weight loss at 6 months in this trial.

“The difference in outcomes between these two trials is likely attributable to differences in dietary counseling,” write the editorialists, Adam Gilden, MD, and Victoria Catenacci, MD, from University of Colorado at Denver, Aurora.

Previous studies of intermittent fasting have been short and showed similar findings, compared with a calorie-restricted diet.

The study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health.

SAN DIEGO – 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.

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.”

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.

“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.

VIENNA – An algorithm, the Steatosis-Associated Fibrosis Estimator (SAFE), was developed to detect clinically significant fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). It is effective at detecting chronic liver disease from all causes with or without NAFLD in the general population, according the results of a U.S. population-based study. The algorithm was designed for use in primary care to help slow the steep rise in liver disease burden.

On the basis of the SAFE score, 61.3% of participants were at low risk for clinically significant fibrosis; 11.2% were at high risk; and 27.5% were at intermediate risk. Upon validation, very few of the low-risk participants had liver fibrosis, while nearly a third of those with a high-risk score had clinically significant fibrosis. In addition, a high percentage of the patients with high-risk SAFE scores had viral hepatitis and elevations in ferritin level.

“This is the first time that there has been a test that provides a score to detect low-risk liver disease in primary care,” said Ray Kim, MD, from Stanford (Calif.) University, senior investigator, who was speaking to this news organization at the annual International Liver Congress sponsored by the European Association for the Study of the Liver

“Primary care doctors currently detect liver disease through a serendipitous abnormal finding on ultrasound or blood tests that detect elevated transaminases, and then the patient is referred to a hepatologist, who figures out what is really going on,” said Dr. Kim.

“This approach is limited, so we need to get SAFE into primary care so these doctors can automatically calculate their scores, and if the patient is over 100 [high risk of chronic liver disease], then they need help [referral to a hepatologist].”
 

Liver deaths sharply rising

Public health data show that more people are dying of liver disease today than previously. Deaths in the United States have doubled over the past 20 years, said Dr. Kim. “If our mission is to help these patients and prevent death, [things are] moving in the wrong direction.”

He stressed that in order to change the direction, “primary care doctors need to engage with the issue and have appropriate tools to identify people with liver disease.”

Most often, the reason for this rise in deaths is that cases are being diagnosed at advanced stages of disease in which reversibility is limited, he added. “We want to move upstream where people might have early-stage disease and where we can intervene and make a difference.”

In an effort to help earlier detection of liver disease, the SAFE score was developed and validated by Dr. Kim and his colleagues to detect clinically significant (greater than stage 2) fibrosis in patients with NAFLD in primary care. The score is based upon age, body mass index, diabetes, platelet level, aspartate and alanine aminotransferase levels, and globulin level. A score of less than zero signifies that a patient is at low risk for liver fibrosis, while a score greater than 100 signifies a high risk of fibrosis. A score between 0 and 99 denotes intermediate risk of fibrosis.

“Unlike other noninvasive tests that detect advanced fibrosis, this one detects early-stage fibrosis. We’ve shown that the SAFE estimator is better than all other blood-based markers,” explained Dr. Kim.
 

Applying SAFE to the general population

In the study presented here at EASL, Dr. Kim aimed to expand the horizon for SAFE testing to the U.S. general population and to assess whether SAFE was effective in screening for chronic liver disease regardless of steatosis of the liver.

Together with first author Nakia Chung, MD, also from Stanford University, Dr. Kim applied the SAFE score to data from 7,156 participants of the National Health and Nutrition Examination Survey (NHANES) for 2017-2020. NHANES is representative of the noninstitutionalized, civilian population of the United States. It includes broad demographic, clinical, and laboratory data, including transient elastography data. FibroScans were first used in 2017, so the investigators had 3 years of FibroScan data with which to validate the score.

The researchers extrapolated the NHANES sample data to the U.S. population. They found that the proportion of adults with steatosis (CAP score > 274 dB/m) and significant fibrosis (LSM > 8.0 kPa) was 42.7% (95% confidence interval, 41.0%- 44.3%) and 8.9% (7.6%-10.2%), respectively. In addition, 11.3% (10.2%-12.5%) of the adult U.S. population demonstrated a significant amount of alcohol use, 2.3% (1.4%-3.3%) showed evidence of hepatitis B or C, and 5.4% (4.6%-6.2%) had elevated serum ferritin levels.

The researchers then stratified the patients according to previously defined SAFE tiers of low, intermediate, and high risk and projected findings to the U.S. general population.

“When we applied our score to the general population, we found multiple abnormalities in the high-risk groups [SAFE >100] having Fibroscan data that are consistent with stage 2 or higher fibrosis regardless of etiology, “Dr. Kim pointed out.

Results also showed that very few patients with SAFE less than 0 had liver fibrosis (4% among those with liver stiffness measure [LSM] > 8kPa, and 0.8% with LSM > 12kPa). Among those with SAFE > 100, nearly a third (31.5%) had LSM of > 8kPa, and 16.5% had LSM > 12kPa.

In addition to fibrosis, liver abnormalities were common among patients with SAFE greater than 100, including steatosis (68.0%), viral hepatitis (7.0%), and abnormal ferritin levels (12.9%); 10.8% of these patients used alcohol.

“Right now, some patients are referred, but on examination and FibroScan, they might actually be okay, so it it’s a waste of time and money for everyone. We can preempt all of this by doing a blood test and focusing on those people who really need a scan,” said Dr. Kim.

The researcher is now working with primary care colleagues to help further develop and integrate SAFE into the primary care setting.
 

Fibrosis score in patients with metabolic dysfunction

Also presenting at the same session on population health was Willem Pieter Brouwer, MD, PhD, from Erasmus University Medical Center, Rotterdam, the Netherlands. He reported results of a validation study of a new risk score – the Metabolic Dysfunction-Associated Fibrosis–5 (MAF-5) score – for use for people with metabolic dysfunction who are recommended for screening for liver fibrosis.

“We believe the MAF-5 score may be a good alternative to the FIB-4 [a liver fibrosis biomarker] for use in the referral pathway for liver health evaluation,” remarked Dr. Brouwer. “The clinical practice guidelines recommend using FIB-4 scores, but these have a poor-moderate performance in the population setting.

“We developed and validated our score in a population of 5,500 from the NHANES 2017-2020 cycle and validated the score in populations from Rotterdam, which is a cohort of elderly participants, and in fibrosis among patients with biopsy-proven NAFLD from Colombia and Belgium,” he explained.

He also validated the score against different existing scoring systems and different methods of measuring liver stiffness and validated it for prognostic use to predict all-cause mortality in the NHANES III cohort.

Dr. Brouwer removed age as a factor of his new MAF-5 score; the score is thus stable for patients of all ages and is suitable for detecting liver disease in younger patients. “This is very important because these patients are currently underserved and have the most years of life to win.”

Referring to the SAFE score discussed by Dr. Kim, as well as other scores, he said, “The FIB-4, SAFE, and NFS [NAFLD fibrosis score] all include age in the scores, which causes problems and limitations in aging populations, as more and more patients will be referred due to an increasing score. Hence, the elderly are mostly all referred for liver checkups.”

Dr. Kim and Dr. Brouwer have disclosed no relevant financial relationships.

VIENNA – An algorithm, the Steatosis-Associated Fibrosis Estimator (SAFE), was developed to detect clinically significant fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). It is effective at detecting chronic liver disease from all causes with or without NAFLD in the general population, according the results of a U.S. population-based study. The algorithm was designed for use in primary care to help slow the steep rise in liver disease burden.

On the basis of the SAFE score, 61.3% of participants were at low risk for clinically significant fibrosis; 11.2% were at high risk; and 27.5% were at intermediate risk. Upon validation, very few of the low-risk participants had liver fibrosis, while nearly a third of those with a high-risk score had clinically significant fibrosis. In addition, a high percentage of the patients with high-risk SAFE scores had viral hepatitis and elevations in ferritin level.

“This is the first time that there has been a test that provides a score to detect low-risk liver disease in primary care,” said Ray Kim, MD, from Stanford (Calif.) University, senior investigator, who was speaking to this news organization at the annual International Liver Congress sponsored by the European Association for the Study of the Liver

“Primary care doctors currently detect liver disease through a serendipitous abnormal finding on ultrasound or blood tests that detect elevated transaminases, and then the patient is referred to a hepatologist, who figures out what is really going on,” said Dr. Kim.

“This approach is limited, so we need to get SAFE into primary care so these doctors can automatically calculate their scores, and if the patient is over 100 [high risk of chronic liver disease], then they need help [referral to a hepatologist].”

CHICAGO – Treatment of hyperthyroidism with surgery or radioactive iodine significantly extends survival, compared with antithyroid medication, while surgery raises the risk for obesity, new data from a large cohort study suggest.

“I think this is something we need to take into our discussions with patients because treatment for hyperthyroidism is very much individualized decision-making ... The effects on mortality are not usually one of the factors we discuss there. But now, we have strong data from a very large cohort of patients indicating that this is something that does need to be discussed,” lead author Kristien Boelaert, MD, who is the current president of the British Thyroid Association, said in an interview.

Dr. Boelaert presented the findings of the EGRET (Weight Changes, Cardio-Metabolic Risks and Mortality in Patients With Hyperthyroidism) study at the Annual Meeting of the Endocrine Society.

Other notable findings from EGRET were that the patients on antithyroid medication were thinner than expected, suggesting undertreatment, and that no differences were found for major adverse cardiac events (MACE) across the treatment options, leaving unexplained the reasons for the increased mortality in the medicated group.

Asked to comment, session moderator Spyridoula Maraka, MD, said: “I think this is very important work because so far when we counsel our patients about the different treatment modalities we focus more on risk for recurrence and other short-term outcomes.”

“But these data give us a bigger perspective on mortality and cardiovascular outcomes ... We haven’t had such good quality data to accurately counsel our patients,” added Dr. Maraka, of the University of Arkansas for Medical Sciences, Little Rock.
 

Mortality higher for medication-treated, but why?

“Hyperthyroidism or an overactive thyroid gland is common, affecting up to 3% of the population, and is associated with long-term adverse cardiac and metabolic consequences. The optimal treatment choice remains unclear,” explained Dr. Boelaert, professor of endocrinology at the University of Birmingham, England, outlining the reasons they conducted the EGRET study.

The study population was 55,318 patients (77% women) with newly diagnosed hyperthyroidism identified from a U.K. population-based primary care electronic health record database. Of those, 77.8% were treated with antithyroid medication, 14.6% with radioactive iodine, and 7.8% with surgery (total or hemithyroidectomy). The health records were linked with national mortality data and Health Survey England data on body mass index (BMI) for comparison.

Dr. Boelaert noted that the trial design “is the best we have” because a randomized clinical trial comparing hyperthyroid treatments would be extremely difficult given the need to individualize therapy and the impossibility of blinding. On the other hand, with the current study, “it’s certainly the largest patient group we’ve looked at.”

Over an average 12.1 years of follow-up, the proportion of patients who died was 14.1% in the medication group, 18.7% of those who had radioiodine therapy, and 9.2% of those who underwent surgery.

Compared with the number who would have been expected to die based on the general background population, the likelihood of reduced life expectancy for the treated groups was increased 2.10-fold for radioiodine, 2.13-fold for surgery, and 2.71-fold for medication. All were significantly higher than the general population (P < .0001).

After further adjustment for multiple confounders, mortality risk was reduced in patients treated with radioiodine (by 13%) or surgery (by 20%), compared with those treated with antithyroid medication, both significant reductions (P < .0001).

After exclusion of the 3.9% with baseline cardiovascular disease, MACE (defined as cardiovascular death or hospitalization for stroke or myocardial infarction) occurred in 9.9%, 13.4%, and 8.0% of the medication, radioiodine, and surgery groups, respectively.

After adjustments, there were no differences in MACE, compared with medications, with hazard ratios of 1.00 (P = .94) for radioactive iodine and 0.97 for surgery (P = .61).

“We were expecting to see a reduction in cardiovascular events, as previous studies suggest that radioactive iodine patients have fewer cardiovascular deaths. We did not see that but our protocol wasn’t set up to get every single specific cause of death. That will require further ongoing analysis,” said Dr. Boelaert.
 

Weight gain: Worth it for longer life

Compared with the background population, thyroidectomy was associated with an increased likelihood of developing obesity (BMI > 30 kg/m²) in both men (odds ratio, 1.56; P < .001), and women (OR, 1.27; P < .001), while radioiodine increased obesity risk in women (OR, 1.12; P < .001) but not in men (OR, 1.03; P = .55).

Among the women, those treated with antithyroid medications had an average 0.28 kg/m² lower BMI, compared with the background population, and those treated with surgery had a 0.83 kg/m² higher BMI. Both differences were significant (P < .001).

The BMI differences were not significant for radioactive iodine in women and for medications and radioactive iodine in men, although the men treated surgically also had a significantly higher BMI (1.09 kg/m²; P < .001).

“The patients on antithyroid drugs were lighter than we would expect. I think that’s ongoing hyperthyroidism. I strongly believe that ... to get rid of hyperthyroidism you have to make patients hypothyroid ... It’s really important that you get good control,” Dr. Boelaert commented.

Dr. Maraka, who is also endocrine section chief of the Arkansas Veteran’s Healthcare System, Little Rock, commented: “[Dr. Boelaert’s] concern is that the patients on antithyroid drugs are not adequately controlled, and we know very well that uncontrolled hyperthyroidism is associated with increased mortality and increased cardiovascular outcomes. This suggests that if patients are on antithyroid medications, they should at least be monitored very well.”

Regarding the possible cause of the increased mortality, if not cardiovascular, Dr. Maraka also pointed out that typically once antithyroid medications are stopped, about half of patients will stay in remission and the other half will return to hyperthyroidism.

“It might be that this kind of ‘yo-yo’ is what’s actually leading to the increased mortality, compared to patients who had definitive treatment and this problem was taken care of. This is speculation but it might be what we’re seeing,” Dr. Maraka observed.

The BMI differences worked out to a weight gain with surgery of approximately 2.1 kg (4.6 lb) for a woman with a height of 160 cm and 2.4 kg for 170 cm. Among men, those differences were 3.2 kg and 3.5 kg for heights of 170 cm and 190 cm, respectively.

Dr. Boelaert said, “I think we should discuss this with patients. They will say they don’t want to get fat, but the absolute weight gain is ... not that much.”

“I personally think that 2 kg is not a big price to pay to live longer. I hope that’s what we’ll be telling our patients in clinic in the next few years after we get this published.”

Dr. Boelaert and Dr. Maraka have reported no relevant financial relationships.

Among the women, those treated with antithyroid medications had an average 0.28 kg/m² lower BMI, compared with the background population, and those treated with surgery had a 0.83 kg/m² higher BMI. Both differences were significant (P < .001).

The BMI differences were not significant for radioactive iodine in women and for medications and radioactive iodine in men, although the men treated surgically also had a significantly higher BMI (1.09 kg/m²; P < .001).

“The patients on antithyroid drugs were lighter than we would expect. I think that’s ongoing hyperthyroidism. I strongly believe that ... to get rid of hyperthyroidism you have to make patients hypothyroid ... It’s really important that you get good control,” Dr. Boelaert commented.

Dr. Maraka, who is also endocrine section chief of the Arkansas Veteran’s Healthcare System, Little Rock, commented: “[Dr. Boelaert’s] concern is that the patients on antithyroid drugs are not adequately controlled, and we know very well that uncontrolled hyperthyroidism is associated with increased mortality and increased cardiovascular outcomes. This suggests that if patients are on antithyroid medications, they should at least be monitored very well.”

Regarding the possible cause of the increased mortality, if not cardiovascular, Dr. Maraka also pointed out that typically once antithyroid medications are stopped, about half of patients will stay in remission and the other half will return to hyperthyroidism.

“It might be that this kind of ‘yo-yo’ is what’s actually leading to the increased mortality, compared to patients who had definitive treatment and this problem was taken care of. This is speculation but it might be what we’re seeing,” Dr. Maraka observed.

The BMI differences worked out to a weight gain with surgery of approximately 2.1 kg (4.6 lb) for a woman with a height of 160 cm and 2.4 kg for 170 cm. Among men, those differences were 3.2 kg and 3.5 kg for heights of 170 cm and 190 cm, respectively.

Dr. Boelaert said, “I think we should discuss this with patients. They will say they don’t want to get fat, but the absolute weight gain is ... not that much.”

“I personally think that 2 kg is not a big price to pay to live longer. I hope that’s what we’ll be telling our patients in clinic in the next few years after we get this published.”

Dr. Boelaert and Dr. Maraka have reported no relevant financial relationships.

CHICAGO – Treatment of hyperthyroidism with surgery or radioactive iodine significantly extends survival, compared with antithyroid medication, while surgery raises the risk for obesity, new data from a large cohort study suggest.

“I think this is something we need to take into our discussions with patients because treatment for hyperthyroidism is very much individualized decision-making ... The effects on mortality are not usually one of the factors we discuss there. But now, we have strong data from a very large cohort of patients indicating that this is something that does need to be discussed,” lead author Kristien Boelaert, MD, who is the current president of the British Thyroid Association, said in an interview.

Dr. Boelaert presented the findings of the EGRET (Weight Changes, Cardio-Metabolic Risks and Mortality in Patients With Hyperthyroidism) study at the Annual Meeting of the Endocrine Society.

Other notable findings from EGRET were that the patients on antithyroid medication were thinner than expected, suggesting undertreatment, and that no differences were found for major adverse cardiac events (MACE) across the treatment options, leaving unexplained the reasons for the increased mortality in the medicated group.

Asked to comment, session moderator Spyridoula Maraka, MD, said: “I think this is very important work because so far when we counsel our patients about the different treatment modalities we focus more on risk for recurrence and other short-term outcomes.”

“But these data give us a bigger perspective on mortality and cardiovascular outcomes ... We haven’t had such good quality data to accurately counsel our patients,” added Dr. Maraka, of the University of Arkansas for Medical Sciences, Little Rock.
 

Mortality higher for medication-treated, but why?

“Hyperthyroidism or an overactive thyroid gland is common, affecting up to 3% of the population, and is associated with long-term adverse cardiac and metabolic consequences. The optimal treatment choice remains unclear,” explained Dr. Boelaert, professor of endocrinology at the University of Birmingham, England, outlining the reasons they conducted the EGRET study.

The study population was 55,318 patients (77% women) with newly diagnosed hyperthyroidism identified from a U.K. population-based primary care electronic health record database. Of those, 77.8% were treated with antithyroid medication, 14.6% with radioactive iodine, and 7.8% with surgery (total or hemithyroidectomy). The health records were linked with national mortality data and Health Survey England data on body mass index (BMI) for comparison.

Dr. Boelaert noted that the trial design “is the best we have” because a randomized clinical trial comparing hyperthyroid treatments would be extremely difficult given the need to individualize therapy and the impossibility of blinding. On the other hand, with the current study, “it’s certainly the largest patient group we’ve looked at.”

Over an average 12.1 years of follow-up, the proportion of patients who died was 14.1% in the medication group, 18.7% of those who had radioiodine therapy, and 9.2% of those who underwent surgery.

Compared with the number who would have been expected to die based on the general background population, the likelihood of reduced life expectancy for the treated groups was increased 2.10-fold for radioiodine, 2.13-fold for surgery, and 2.71-fold for medication. All were significantly higher than the general population (P < .0001).

After further adjustment for multiple confounders, mortality risk was reduced in patients treated with radioiodine (by 13%) or surgery (by 20%), compared with those treated with antithyroid medication, both significant reductions (P < .0001).

After exclusion of the 3.9% with baseline cardiovascular disease, MACE (defined as cardiovascular death or hospitalization for stroke or myocardial infarction) occurred in 9.9%, 13.4%, and 8.0% of the medication, radioiodine, and surgery groups, respectively.

After adjustments, there were no differences in MACE, compared with medications, with hazard ratios of 1.00 (P = .94) for radioactive iodine and 0.97 for surgery (P = .61).

“We were expecting to see a reduction in cardiovascular events, as previous studies suggest that radioactive iodine patients have fewer cardiovascular deaths. We did not see that but our protocol wasn’t set up to get every single specific cause of death. That will require further ongoing analysis,” said Dr. Boelaert.

SAN DIEGO – 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.

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.

SAN DIEGO – 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.

SAN DIEGO – 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.

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.

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.

More than 140 million Americans use artificial sweeteners, a habit driven by the irrefutable fact that excess sugar is harmful. But I’m continually amazed by alarmist headlines on the topic.

In May, the World Health Organization (WHO) released a report to support its “conditional recommendation” against the use of non-sugar sweeteners (NSS) for weight control. Despite the WHO’s goal “to provide evidence-informed guidance,” the report includes the disclaimer that “The recommendation is based on evidence of low certainty.”

Low certainty is an accurate descriptor for the findings of many of the 280-plus studies in the report. That the guidance does not apply to patients with diabetes was easily lost in the repeated mentions of the perceived dangers of these sugar alternatives.

The review included various table-top and beverage sweeteners, including acesulfame K, aspartame, saccharin, sucralose, stevia, and stevia derivatives. Low-calorie sugars and sugar alcohols such as erythritol were excluded.

The WHO looked at long- and short-term trials, randomized controlled trials (RCTs), prospective studies, and case-control studies measuring a wide range of endpoints, from dental caries to cancer. The report highlighted that some findings cannot be attributed directly to NSS use but may simply be due to their substitution for sugar. Differences in outcomes due to sex, ethnicity, and body weight status could not be assessed either. And the WHO conceded the possibility of reverse causation in observational studies wherein higher-risk individuals may consume more NSS.

Nonnutritive sweeteners are given little credit for weight loss. “A significant difference in body weight and BMI was only observed in trials that reported a reduction in energy intake ... rather than primarily by an inherent property of NSS that can modulate body weight (independently of energy intake),” the report reads. But isn’t the desired effect of using an artificial sweetener instead of table sugar that you lower your calorie intake?

The WHO noted that weight loss was not sustained – a finding in nearly every weight loss trial in history and something more attributable to human nature than the sweetener one chooses.

The document outlines that meta-analyses of prospective cohort studies show that higher intakes of NSS were associated with an increased risk for type 2 diabetes and elevated fasting glucose, while meta-analyses of randomized trials suggest no significant effect on “biomarkers used in the assessment and diagnosis of diabetes and insulin resistance, including fasting glucose, fasting insulin and hemoglobin A1c.”

Similar disparities are noted with cardiovascular risk. Prospective trials suggest an increased risk for CVD, including stroke and its precursor, hypertension; but again, the RCT data found no evidence to suggest a significant effect “on biomarkers used in the assessment and diagnosis of CVDs, including blood pressure, low-density lipoprotein cholesterol and other blood lipids.”
 

Splenda and stevia under fire

Predictably, some in the nonnutritive sweetener industry are incensed.

Ted Gelov, CEO of Heartland Food Products Group, maker of Splenda, responded in a press release, “Every few years now it seems I have to come to you and clarify misleading headlines ... Suggesting that sweeteners like Splenda cannot have long-term benefits is a disservice to healthcare providers, their patients, and all consumers.”

Splenda has been on the U.S. market since 1999, and Mr. Gelov reportedly uses three to eight packets daily in his coffee and tea.

I reached out to Heartland and they sent me an eight-page document consisting of over 50 statements, summaries, and clinical trials supporting the safety of artificial sweeteners, including sucralose, an ingredient in Splenda. In 2016, Mr. Gelov rebutted claims that sucralose was linked to cancer in Swiss male mice. These “dramatized headlines are based on one flawed study by an isolated Italian research laboratory, the Ramazzini Institute,” Mr. Gelov wrote.

Another recent headline was about the DNA-damaging effects of sucralose-6-acetate (S6A) seen in an in vitro study published in the Journal of Toxicology and Environmental Health. According to the authors, commercial sucralose samples contain up to 0.67% S6A, a manufacturing impurity.

Despite many reports linking this study to Splenda, Heartland wrote that “Splenda and its ingredients were never studied or tested in this research. We, and our suppliers, rigorously and routinely test and monitor for any impurities in our products. We can confirm that S6A is not present in Splenda Brand sucralose down to the lowest detection limit possible, which is .001% sensitivity level.”

F. Perry Wilson, MD, director of Clinical and Translational Research Accelerator at Yale and a regular contributor to this news organization, took to Twitter to put this study in context: “The human exposure equivalent to sucralose would be 60 packets per day,” he pointed out. And the blood levels of S6A with normal consumption would not “come close to the DNA damage threshold noted in the article.”

Perhaps the most concerning scientific data suggesting a link between artificial sweetener use and ill health is a Cleveland Clinic study showing an association between higher blood levels of erythritol and adverse cardiovascular outcomes such as heart attack, stroke, or death. The researchers also found that erythritol, which is found in stevia and some keto food products, made platelet activation and clot formation easier.

When I asked about these findings, Heartland stated, “The study was primarily conducted on patients who were at an elevated risk of cardiovascular events due to their advanced age, elevated body mass and presence of pre-existing health conditions ... the stated findings were only an association and cannot imply causation.”

The main conclusion I’ve drawn on the topic of artificial sweeteners is that a lot of resources were wasted in performing underpowered, poorly designed trials on compounds that are already generally regarded as safe (GRAS) by the FDA. The WHO “conditional guideline” is, by its own description, based on a plethora of “low certainty” to “very low certainty” evidence.

The monies to produce the WHO report and many of these trials would have been better spent educating the public on the difference between simple and complex carbohydrates; the inflammatory and disease-producing effects of excess sugars; and how to prevent, diagnose, and treat diabetes.

If more trials on artificial sweeteners are planned, they should be performed on people doing human things – which does not include ingesting 60 packets of any sweetener in a single day.

In my personal N-of-1 trial, consuming sugar makes me crave more, feel sluggish, and gain weight. I don’t believe that NSS alone will control my weight. But I’ll continue to drink two cups of stevia-laced coffee every morning, take walks, avoid alcohol, eat my vegetables, and hope for the best.
