iStock, Vectorian Pemvidutide showed a “highly statistically significant” treatment effect in patients with alcohol use disorder. Altimmune is going up against Eli Lilly and newcomer Baseline Therapeutics in this space. Altimmune’s investigational GLP-1/GIP injection met the primary and key secondary endpoints in a mid-stage trial involving patients with alcohol use disorder. In the Phase 2 RECLAIM study , Altimmune enrolled 100 patients who were randomly assigned to receive the experimental therapy, dubbed pemvidutide, or placebo. Topline results revealed Tuesday showed that participants on pemvidutide had 4.20 fewer heavy drinking days—defined as having five drinks for men and four for women—per week, on average, at 24 weeks versus baseline. Meanwhile, in the placebo group, heavy drinking days decreased by 2.75 days per week on average over the same time period. The treatment effect was “highly statistically significant” in favor of pemvidutide, Altimmune said in its press release. ezstandalone.cmd.push(function () { ezstandalone.showAds(129); }); Shares of the biotech jumped as much as 19% to $3.51 in premarket trading. Pemvidutide also aced key secondary trial endpoints, including the proportion of patients with zero heavy drinking days in the final weeks of the study, the percentage of days with alcohol abstinence and serum phosphatidyl ethanol levels, a biomarker of alcohol intake. A “generally favorable” tolerability pro observed. Altimmune is “extremely encouraged” by these findings, Chief Medical Officer Christophe Arbet-Engels said in a prepared statement. With these data in hand, the biotech will request an end-of-Phase 2 meeting with the FDA to determine the path forward for pemvidutide in this indication. RECLAIM’s results will also be presented at an upcoming scientific congress and will be filed for publication in a peer-reviewed journal. Designed as a weekly under-the-skin injection, pemvidutide is a dual agonist of the GLP-1 and GIP receptors—a targeting pro Arbet-Engels said could set the drug apart in the alcohol use disorder (AUD) arena. “Given the known detrimental effects of alcohol on the liver, the liver-directed impact of glucagon in pemvidutide may provide further benefit in the treatment of AUD over GLP-1 alone, underscoring pemvidutide’s promising potential differentiation,” he said on Tuesday. Aside from AUD, Altimmune is also advancing pemvidutide for metabolic dysfunction-associated steatohepatitis. In a Phase 2b study , the candidate elicited significantly improved disease resolution versus placebo, the biotech reported in November 2025. The findings point to “class-leading signals” for pemvidutide, H.C. Wainwright said at the time, further predicting that Altimmune could see peak annual sales topping $1 billion in this indication. MASH Altimmune Poised for $1B+ Opportunity as MASH Drug Aces Phase IIb Altimmune’s pemvidutide showed “class-leading signals” in non-invasive assessments and has “potentially best-in-class tolerability,” according to analysts at H.C. Wainwright.

AUD appears to be of particular interest for biopharma. Eli Lilly, a frontrunner in this drug class, has two Phase 3 trials underway in AUD for its investigational GLP-1/GIP asset brenipatide—one focusing on patients with moderate-to-severe disorder, and another that does not list this enrolment restriction. Joining Lilly is Baseline Therapeutics, which launched in January to advance a weekly GLP-1 drug for AUD, with plans to push into late-stage development this year. GLP-1 7 Indications for GLP-1s Beyond Weight Loss Already established as cornerstone therapies in diabetes and obesity, GLP-1 receptor agonists also show potential in several other indications, including cancer, addiction and neurodegenerative diseases.
