Liisa Bayko's questions to Altimmune Inc (ALT) leadership • Q1 2025
Question
Liisa Bayko of Evercore ISI asked about patient discontinuation rates in the IMPACT study, the importance and expected benchmark for weight loss, and potential Phase 3 trial design elements like dose and endpoint timing.
Answer
CBO Ray Jordt expressed satisfaction with the trial's discontinuation rates and highlighted that weight loss is a key differentiator, benchmarking it against semaglutide's results adjusted for a 24-week timeline. CEO Dr. Vipin Garg confirmed they are strongly considering using the higher 2.4mg dose in Phase 3 to maximize weight loss and are also considering a 6-month endpoint to potentially accelerate the development timeline, pending FDA discussions.
