Oral Obesity Drug Pipeline Heats Up as Competitors Eye Eli Lilly’s Market Lead
SHERIDAN, WYOMING – August 12, 2025 – Eli Lilly’s Phase III results for its next-generation oral GLP-1 therapy, orforglipron, have energized the already competitive obesity drug market, sparking renewed focus on oral weight-loss candidates poised to challenge the injectable-dominated landscape. While Lilly’s data confirmed significant efficacy, industry analysts see room for competitors to gain ground with differentiated mechanisms, dosing advantages, and manufacturing scalability.
The ATTAIN-1 study showed orforglipron achieved an average 12.4% weight reduction over 72 weeks, compared with 0.9% for placebo, with nearly 60% of high-dose patients losing at least 10% of body weight. However, analysts at Truist Securities and William Blair noted the therapy’s performance fell short of expectations set by leading injectable GLP-1 agonists—creating an opening for rivals.
