The Attain-2 study, which involved 1,600 participants with obesity or overweight and Type 2 diabetes, demonstrated that orforglipron's 36 mg dose achieved an average weight loss of 22.9 pounds over 72 weeks. This result, while slightly below the 11.5% placebo-adjusted weight loss observed in the Attain-1 study, is promising compared to other trials. For instance, Wegovy's 68-week placebo-adjusted weight loss was 7.5%, and 25 mg oral semaglutide's total weight loss was 7% in the Pioneer Plus trial.
The company's shares reacted positively to the news, indicating investor confidence in Lilly's ability to secure regulatory approval for orforglipron. However, Morningstar analysts caution that Novo's oral semaglutide may still be a significant competitor in the US oral obesity market, with approval expected ahead of Lilly and slightly stronger data in its main obesity/overweight trial. Despite this, Lilly's easier manufacturing process for orforglipron could allow for a more rapid global launch.
In summary, Eli Lilly's orforglipron achieved promising results in the Attain-2 study, supporting its regulatory filings and maintaining investor confidence in the company's stock. The data also highlights Lilly's competitive position in the growing oral obesity market.
