Adamas Pharmaceuticals, Inc.

On March 4, 2019, Adamas revised previous prescription growth estimates for GOCOVRI, the Company’s primary product, warned of a continued slowdown in GOCOVRI prescriptions, and refused to predict GOCOVRI’s ability to achieve a sizeable market share.

On this news, Adamas’ share price fell $3.99 per share, or more than 32%, to close at $8.16 per share on March 5, 2019, thereby injuring investors.

Then, on September 30, 2019, an analyst lowered its rating on Adamas due to “existing overhangs,” including lack of “Gocovri coverage: a number of national formularies exclude Gocovri.” The analyst “expect[ed] reimbursement hurdles in MSWI space especially with generic Ampyra launch.”

On this news, Adamas’ share price fell $3.02 per share, or more than 42%, over several trading sessions to close at $4.03 per share on October 3, 2019, thereby injuring investors further.

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 health insurers were excluding Adamas's primary product, GOCOVRI, from their prescription formularies or requiring patients to use "step therapy" - i.e., making patients try immediate-release amantadine prior to covering GOCOVRI; (2) that the rapid increase in physicians prescribing GOCOVRI during the Class Period was not due to its efficacy; and (3) that as a result of the foregoing, the Company's financial statements about Adamas's business, operations, and prospects were materially false and misleading at all relevant times.
