Impressively, the trial met its primary endpoint, showcasing a significant reduction in heavy drinking days when compared to placebo, which has important implications for the treatment environment. In conjunction with this, the trial confirmed positive outcomes across key secondary endpoints, including a decrease in World Health Organization Risk Drinking Level classifications.

Clinical Trial Details

The RECLAIM trial's findings marked key progress for Altimmune, given the challenging nature of AUD treatment. Alongside reducing heavy drinking days, participants showed a marked decline in phosphatidyl ethanol levels and even reported zero heavy drinking days, key FDA registrational endpoints. A favorable safety and tolerability profile was also noted, positioning Pemvidutide as a promising candidate for further development.

The next steps involve engaging with the FDA to discuss the trial results and outline future regulatory interactions, enhancing the company's potential pathway to market.
