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.” After the market closed on November 25, 2019, ChemoCentryx announced “Positive Topline Data from Pivotal Phase III ADVOCATE Trial Demonstrating Avacopan’s Superiority Over Standard of Care in ANCA-Associated Vasculitis.” In this announcement, ChemoCentryx stated that the ADVOCATE Phase III Trial “met both of its primary endpoints,” and that “[t]he topline safety results revealed an acceptable safety profile in this serious and life-threatening disease.” Over the next several months, defendants continued to repeatedly laud the results of the ADVOCATE Phase III trial, as well as the safety profile of avacopan for the treatment of ANCA-associated vasculitis. On July 9, 2020, ChemoCentryx announced that it had filed its New Drug Application (“NDA”) for avacopan, and on September 17, 2020, the Company announced that the U.S. Food & Drug Administration (“FDA”) had accepted the NDA for review.

The ChemoCentryx class action lawsuit alleges that, throughout the Class Period, defendants made false and misleading statements and failed to disclose that: (i) 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 ANCA-associated vasculitis; (ii) the data from the Phase III ADVOCATE trial raised serious safety concerns for avacopan; (iii) these issues presented a substantial concern regarding the viability of ChemoCentryx’s NDA for avacopan for the treatment of ANCA-associated vasculitis; and (iv) as a result of the foregoing, defendants’ public statements were materially false and misleading at all relevant times.

On May 4, 2021, the FDA published a Briefing Document concerning ChemoCentryx’s NDA for avacopan. In this Briefing Document, the FDA wrote that “[c]omplexities of the study design, as detailed in the briefing document, raise questions about the interpretability of the data to define a clinically meaningful benefit of avacopan and its role in the management of [ANCA-associated vasculitides].” The FDA Briefing Document continued that “[a]lthough primary efficacy comparisons were statistically significant, the review team has identified several areas of concern, raising uncertainties about the interpretability of these data and the clinical meaningfulness of these results.” The FDA also raised serious safety concerns with avacopan for the treatment of ANCA-associated vasculitis. On this news, the price of ChemoCentryx common stock fell approximately 45%, damaging investors.
