Lilly Plans NDA for Obesity Pill; Positive Data Released
Eli Lilly says it will soon seek FDA approval for its investigational obesity pill orforglipron following its 8/26 release of “positive topline results” from the Phase 3 ATTAIN-2 trial that evaluated the oral GLP-1 receptor agonist in obese or overweight adults with Type 2 diabetes. “In the trial, all three doses of orforglipron met the primary and all key secondary endpoints, delivering significant weight loss, meaningful A1C reductions, and improvements in cardiometabolic risk factors at 72 week,” the company says. "For the primary endpoint, orforglipron 36 mg, taken once per day without food and water restrictions, lowered weight by an average of 10.5% (22.9 lbs) compared to 2.2% (5.1 lbs) with placebo using the efficacy estimand.”
The drug also improved blood sugar control, with hemoglobin A1C levels falling by as much as 1.8 percentage points from a baseline of 8.1%, Lilly says. Three-quarters of participants on the highest dose achieved an A1C at or below 6.5%, the American Diabetes Association’s threshold for diabetes, it adds.
Orforglipron’s safety profile was also in line with other GLP-1 drugs such as semaglutide, with gastrointestinal side effects like nausea, diarrhea, and vomiting being the most common complaints, according to Lilly. Rates of discontinuation due to side effects ranged from 6% to 11% across doses, similar to placebo.
Lilly notes it is also studying the pill in conditions linked to obesity, including sleep apnea and hypertension.
