Eli Lilly's Oral GLP-1 Orforglipron Shows Promising Weight Loss Results
Eli Lilly's investigational oral GLP-1 receptor agonist, orforglipron, has demonstrated compelling efficacy in Phase 3 trials for weight loss and A1C reduction in adults with obesity or overweight and type 2 diabetes. These results pave the...
Key Insights
- Orforglipron led to an average weight loss of 10.5% (22.9 lbs) at the highest dose (36 mg) in a 72-week trial (ATTAIN-2), compared to 2.2% (5.1 lbs) with placebo.
- A1C levels were reduced by an average of 1.3% to 1.8% from a baseline of 8.1% across different doses of orforglipron.
- 75% of participants taking the highest dose of orforglipron achieved an A1C ≤6.5%, meeting the American Diabetes Association's definition of diabetes.
- Orforglipron showed clinically meaningful benefits across key cardiovascular risk factors, including non-HDL cholesterol, systolic blood pressure, and triglycerides.
- Why does this matter? Orforglipron offers a convenient, once-daily oral option for weight loss and diabetes management, potentially increasing accessibility and adherence compared to injectable GLP-1 medications. The availability of an oral GLP-1 could significantly expand treatment options for patients who prefer oral therapies without sacrificing clinical results. This could lead to better management of diabetes and obesity, reducing the risk of associated health complications.
In-Depth Analysis
Eli Lilly's orforglipron is a once-daily small molecule oral glucagon-like peptide-1 (GLP-1) receptor agonist. The Phase 3 ATTAIN-2 trial (NCT05872620) was a 72-week, randomized, double-blind, placebo-controlled study involving over 1,600 participants across multiple countries. Participants with a BMI ≥27.0 kg/m² and type 2 diabetes were treated with orforglipron (6 mg, 12 mg, or 36 mg) or placebo.
The study met its primary endpoint, demonstrating that orforglipron is superior to placebo in mean body weight change from baseline at 72 weeks. The treatment-regimen estimand also showed statistically significant improvements across primary and key secondary endpoints.
The most common adverse events associated with orforglipron were gastrointestinal-related (nausea, vomiting, diarrhea, constipation, and dyspepsia) and generally mild to moderate in severity. Discontinuation rates due to adverse events were comparable to placebo.
Orforglipron's success in Phase 3 trials has triggered global regulatory submissions, with potential approval and availability expected in the near future. Kenneth Custer, Ph.D., Lilly executive vice president, emphasized the urgency to meet the needs of patients and the potential for global scalability of this convenient oral treatment.
