Amylyx Pharmaceuticals, Inc. is a commercial-stage biotechnology company that engages in the discovery and development of treatments for ALS, also known as Lou Gehrig’s disease, and other neurodegenerative diseases. The Company’s products include, among others, AMX0035 (commercially referred to as “RELYVRIO” in the U.S.), a dual UPR-Bax apoptosis inhibitor composed of sodium phenylbutyrate and taurursodiol, for the treatment of ALS in adults in the U.S.

A recently filed securities fraud class action complaint alleges that, Amylyx Pharmaceuticals, Inc., through certain of its officers and directors, made materially false and misleading statements regarding the Company’s business, operations, and prospects in that: (i) Defendants had overstated RELYVRIO’s commercial prospects; (ii) patients were discontinuing treatment with RELYVRIO after six months; (iii) the rate at which new patients were starting treatment with RELYVRIO was decreasing; (iv) accordingly, Defendants had also overstated RELYVRIO’s prescription rate; (v) Defendants attempted to hide the foregoing negative trends from investors and the market by blocking analysts from viewing RELYVRIO’s prescription data; and (vi) as a result, Defendants’ public statements were materially false and misleading at all relevant times.
