In context
“isorder. We expect to initiate several more phase II and phase III trials in 2026, exploring how brenepatide may be able to treat other conditions, including a phase three trial for major depressive disorder, testing if brenepatide can prevent relapse of disease. In Alzheimer's disease, we continue to look forward to the results from Trailblazer ALS3, our study of donanemab in people with normal cognition but a positive blood test for Alzheimer's disease.

This unique phase three trial was designed to answer a common question from doctors and patients: Can people successfully maintain weight loss achieved on the maximum tolerated dose of injectable incretins by switching to an oral GLP-1 therapy? Participants in ATTAINMANTAIN previously on injectable semaglutide or tirzepatide then switched to orforglipron or placebo. As shown on slide 16, orforglipron helped people maintain weight loss that they had achieved on injectable therapies, and the study met all primary and secondary endpoints. People who switched from semaglutide to orforglipron maintain”
