Tesaro is an oncology-focused biopharmaceutical company that identifies, acquires, develops, and commercializes cancer therapeutics and oncology supportive care products in the United States.

At all relevant times, Tesaro’s product portfolio has included Varubi (rolapitant), a neurokinin-1 (NK-1) receptor antagonist for the prevention of chemotherapy induced nausea and vomiting. In 2015, the U.S. Food and Drug Administration (“FDA”) approved an oral version of Varubi. On March 14, 2016, Tesaro announced the submission of a New Drug Application for an intravenous formulation of Varubi to the FDA. On October 25, 2017, Tesaro announced the FDA’s approval of its intravenous version of Varubi.

The Complaint alleges that throughout the Class Period, Defendants made materially false and misleading statements regarding the Company’s business, operational and compliance policies. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) substantial undisclosed health risks, including anaphylaxis and anaphylactic shock, were associated with Tesaro’s intravenous formulation of Varubi; and (ii) as a result of the foregoing, Tesaro’s shares traded at artificially inflated prices during the Class Period, and class members suffered significant losses and damages.

On January 12, 2018, post-market, Tesaro announced that it had updated the U.S. labeling for the intravenous formulation of Varubi after receiving reports of “[a]naphylaxis, anaphylactic shock and other serious hypersensitivity reactions . . . in the post-marketing setting, some requiring hospitalization.” The Company further stated that it “has issued a Dear Healthcare Professional (DHCP) letter.”

On this news, Tesaro’s share price fell $4.07 or 5.85%, to close at $65.52 on January 16, 2018.
