Robbins LLP is Investigating the Allegations that Altimmune, Inc. (ALT) Misled Investors Regarding the Viability and Efficacy of its Weight Loss Drug

Robbins LLP informs investors that a shareholder filed a class action on behalf of all persons and entities that purchased or otherwise acquired Altimmune, Inc. (NASDAQ: ALT) securities between December 1, 2023 and April 26, 2024. Altimmune is a clinical stage biopharmaceutical company that focuses on developing treatments for obesity and liver diseases. The Company’s lead product candidate is pemvidutide, a glucagon-like peptide-1 (“GLP-1”) agonist for the treatment of obesity and metabolic dysfunction-associated steatohepatitis  (“MASH”).  GLP-1 agonists are medications that help lower blood sugar levels and promote weight loss.

The Allegations

According to the complaint, during the class period, defendants failed to disclose that: (i) Altimmune overstated the potential for pemvidutide to stand out from competing GLP-1 agonists based on the drug’s efficacy and tolerability results observed in the MOMENTUM Trial; (ii) accordingly, the MOMENTUM Trial results were less significant to pemvidutide’s clinical, commercial, and competitive prospects than defendants had led investors to believe; and (iii) as a result of all the foregoing, defendants had overstated Altimmune’s prospects for finding a strategic partner to develop pemvidutide. 

Plaintiff alleges that on February 13, 2024, Kerrisdale Capital published a report alleging that “a deeper examination of Altimmune’s data reveals a drug with little chance of competing against either the approved incumbents or the other GLP-1 agonists progressing through clinical trials.” On this news, Altimmune’s stock price fell $1.94 per share, or 18.65%, to close at $8.46 per share on February 13, 2024.

Then, on April 29, 2024, Bloomberg published an article entitled “Altimmune Down as Guggenheim Sees Overhang in No Partnership,” reporting that “Guggenheim Securities downgraded [Altimmune’s] stock to neutral from buy saying [a] partnership for the biotech’s lead asset pemvidutide look[s] ‘increasingly unlikely.’” On this news, Altimmune’s stock price fell $0.87 per share, or 11.98%, to close at $6.39 per share on April 29, 2024.
