Annovis Bio, Inc.


A securities class action has been filed against Annovis Bio, Inc. (ANVS) on behalf of persons and entities that purchased or otherwise acquired Annovis Bio securities between May 21, 2021 through July 28, 2021.  This case has been filed in the USDC – E.D.PA.

Annovis is a clinical stage pharmaceutical company that is developing therapies addressing neurodegeneration, such as Alzheimer’s disease (“AD”), Parkinson’s disease (“PD”), and Alzheimer’s disease in Down syndrome (“AD-DS”). Its lead compound is ANVS401 (Posiphen), an orally administrated drug which purportedly inhibited the synthesis of neurotoxic proteins that are the main cause of neurodegeneration.

On July 28, 2021, after the market closed, Annovis reported interim clinical data from its Phase 2a trial. Among other things, the Company reported that AD patients 25 days after treatment failed to show statistically significant improvement compared to the placebo. Annovis also reported that, although patients showed cognitive improvements in certain areas, the results were not statistically significant.

On this news, the Company’s share price fell $65.94, or 60%, to close at $43.50 per share on July 29, 2021, on unusually heavy trading volume.

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (1) that Annovis’s ANVS401 did not show statistically significant results across two patient populations as to factors such as orientation, judgement, and problem solving; and (2) as a result, Defendants’ statements about its business, operations, and prospects were materially false and misleading and/or lacked reasonable basis at all relevant times.
