SHAREHOLDER ALERT: Kessler Topaz Meltzer & Check, LLP Announces Securities Fraud Class Action Lawsuit Filed Against ChemoCentryx, Inc.

Jun 21, 2021 2:09 PM ET


 The law firm of Kessler Topaz Meltzer & Check, LLP alerts investors that a securities fraud class action lawsuit has been filed against ChemoCentryx, Inc. on behalf of those who purchased or acquired ChemoCentryx common stock between November 26, 2019 and May 3, 2021, inclusive (the "Class Period").

ChemoCentryx is a biopharmaceutical company focused on the development and commercialization of new medications targeting inflammatory disorders, autoimmune diseases, and cancer. ChemoCentryx's lead drug candidate is avacopan, which ChemoCentryx describes as a "potential first-in-class, orally-administered molecule that employs a novel, highly targeted mode of action in the treatment of ANCA vasculitis and other complement-driven autoimmune and inflammatory diseases."

After the market closed on November 25, 2019, ChemoCentryx issued a press release announcing "Positive Topline Data from Pivotal Phase III ADVOCATE Trial Demonstrating Avacopan's Superiority Over Standard of Care in ANCA-Associated Vasculitis."  Throughout the Class Period, the defendants lauded the results of the ADVOCATE Phase III trial, as well as the safety profile of avacopan for the treatment of ANCA-associated vasculitis ("AAV").

However, the truth was revealed on May 3, 2021 when, the United States Food and Drug Administration ("FDA") published a Briefing Document concerning ChemoCentryx's New Drug Application ("NDA") #214487 for avacopan. The FDA also raised serious safety concerns with avacopan for the treatment of ANCA-associated vasculitis.  Following this news, the price of ChemoCentryx's common stock fell over 45% in one day, down from its May 3, 2021 closing price of $48.82 per share to a May 4, 2021 close of $26.63 per share.

The complaint alleges that throughout the Class Period, the defendants misrepresented and/or failed to disclose to investors that: (1) the study design of the Phase III ADVOCATE trial presented issues about the interpretability of the trial data to define a clinically meaningful benefit of avacopan and its role in the management of AAV; (2) the data from the Phase III ADVOCATE trial raised serious safety concerns for avacopan; (3) these issues presented a substantial concern regarding the viability of ChemoCentryx's NDA for avacopan for the treatment of ANCA-associated vasculitis; and (4) as a result of the foregoing, the defendants' public statements were materially false and misleading at all relevant times.

ChemoCentryx investors may, no later than July 6, 2021, seek to be appointed as a lead plaintiff representative of the class through Kessler Topaz Meltzer & Check, LLP, or other counsel, or may choose to do nothing and remain an absent class member.  A lead plaintiff is a representative party who acts on behalf of all class members in directing the litigation.  In order to be appointed as a lead plaintiff, the Court must determine that the class member's claim is typical of the claims of other class members, and that the class member will adequately represent the class.  Your ability to share in any recovery is not affected by the decision of whether or not to serve as a lead plaintiff.
