Altimmune's Bold Move: Expanding Pemvidutide's Reach to Alcohol-Related Disorders

In the ever-evolving landscape of biotechnology, Altimmune Inc. (ALT) is making waves with its innovative weight-loss drug, pemvidutide. The company's recent announcement to expand the drug's potential to Alcohol Use Disorder (AUD) and Alcohol Liver Disease (ALD) has sparked both excitement and skepticism among investors and industry experts. Let's dive into the details and explore the implications of this bold move.

The Science Behind Pemvidutide

Pemvidutide is a GLP-1/glucagon dual receptor agonist, a novel peptide-based therapeutic designed to mimic the effects of diet and exercise on weight loss. By activating both GLP-1 and glucagon receptors, pemvidutide suppresses appetite and increases energy expenditure, leading to significant weight loss and improvements in metabolic health. The drug has shown promising results in clinical trials for obesity and metabolic dysfunction-associated steatohepatitis (MASH), with a 76.4% relative reduction in liver fat at the highest dose compared to 14% for placebo.

Expanding into AUD and ALD

Altimmune's decision to explore pemvidutide's potential in AUD and ALD is a strategic move that leverages the drug's unique mechanism of action. The Phase 2 trials for AUD and ALD are expected to start in the second and third quarters of 2025, respectively. These trials aim to evaluate pemvidutide's efficacy in reducing alcohol cravings, improving liver health, and promoting weight loss.

The primary endpoint for the Phase 2 ALD study is a change in liver stiffness measurement at 24 weeks, with additional readings at 48 weeks. For the Phase 2 AUD study, the primary endpoint is the change in the number of heavy drinking days at 24 weeks. Secondary endpoints include weight loss and changes in biomarkers of alcohol consumption.

Potential Synergies and Challenges

The expansion into AUD and ALD presents potential synergies for Altimmune. Pemvidutide's ability to reduce alcohol cravings and improve liver health could make it a valuable treatment option for patients with these conditions. Additionally, the company's strong financial position, with $132 million in cash, provides a solid runway to support these new trials and key regulatory milestones.

However, there are also challenges to consider. The high level of trial discontinuation observed in pemvidutide's obesity trial, with 24.0% of the treatment group discontinuing due to gastrointestinal adverse events, could pose a similar challenge in the AUD and ALD trials. The company will need to address these safety and tolerability issues to ensure the success of these new indications.

Investor Sentiment and Stock Performance

The upcoming Phase 2 trials for AUD and ALD could significantly influence investor sentiment and Altimmune's stock performance. Key milestones to watch for include the primary and secondary endpoints, safety and tolerability data, regulatory interactions, partnerships, and financial performance. Positive results from these trials could drive substantial shareholder value and propel pemvidutide towards a Phase 3 program.



Conclusion

Altimmune's expansion of pemvidutide into AUD and ALD is a bold move that could significantly enhance the drug's market potential. While there are challenges to overcome, the potential benefits for patients and investors make this a story worth watching. As the trials progress, investors and industry experts will be closely monitoring the data to assess pemvidutide's true potential in these new indications.
