The American Diabetes Association 83rd Scientific Sessions
By Beth Gilbert HealthDay Reporter
The annual meeting of the American Diabetes Association was held this year from June 23 to 26 in San Diego and attracted more than 15,000 participants from around the world, including clinicians, academicians, allied health professionals, and others interested in diabetes. The conference highlighted the latest advances in diabetes research and improving patient care, with presentations focusing on treatment recommendations and advances in management technology.
In two phase 3 studies, OASIS 1 and PIONEER PLUS, Vanita R. Aroda, M.D., of the Brigham and Women’s Hospital and Harvard Medical School in Boston, and colleagues found that higher doses of orally administrated semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist (RA), results in significant weight loss and hemoglobin A1c (HbA1c) reductions.
The OASIS 1 trial evaluated the effect of oral semaglutide on the treatment of obesity, demonstrating superior body weight reduction compared with placebo (15.1 percent mean weight loss with oral semaglutide compared with 2.4 percent with placebo; net difference of 12.7 percent). The PIONEER PLUS trial compared doses of oral semaglutide higher than currently approved (25 and 50 mg daily versus currently approved 14 mg daily), demonstrating significantly superior HbA1c reduction and body weight reduction at both of the higher doses compared with 14 mg in adults with type 2 diabetes. The overall safety of oral semaglutide at these higher doses was consistent with the safety profile of the GLP-1 RA class, with the most frequent adverse events reported being gastrointestinal in nature (i.e., nausea, vomiting).
“For OASIS 1, these results indicate that oral semaglutide 50 mg may provide an effective, future option for people with overweight or obesity who would benefit from a GLP-1 receptor agonist,” Aroda said. “For PIONEER PLUS, superior glycemic control and body weight loss with oral semaglutide 25 and 50 mg compared with the current highest approved dose of 14 mg suggest that higher doses may support individual, tailored treatment goals.”
The OASIS 1 and PIONEER PLUS studies were funded by Novo Nordisk, the manufacturer of semaglutide.
In the masked, randomized CLEAR Outcomes study, Steven E. Nissen, M.D., of the Cleveland Clinic, and colleagues found that bempedoic acid, a nonstatin cholesterol-lowering drug, is effective in reducing low-density lipoprotein cholesterol and the risk for cardiovascular death, nonfatal myocardial infarction (MI), nonfatal stroke, or coronary revascularization among statin-intolerant patients.
For the study, the authors enrolled 13,970 statin-intolerant patients, including 4,206 patients with risk factors for heart disease but without a prior heart-related event, and evaluated the percentage of patients who met the primary efficacy end point (a composite of cardiovascular death, MI, nonfatal stroke, or coronary revascularization). The researchers found that cholesterol lowering with bempedoic acid resulted in a 30 percent reduction in major cardiovascular events, including a 39 percent reduction in cardiovascular death. Two-thirds of the patients in the study had diabetes.
“High-risk patients are currently undertreated with statins or other cholesterol-lowering drugs,” Nissen said. “This study is a wake-up call that providers need to prescribe cholesterol-lowering drugs more consistently in this group of patients.”
The study was funded by Esperion Therapeutics, the manufacturer of bempedoic acid.
