Thieler Law Corp advises investors with losses exceeding $100,000 of the March 19, 2018 lead plaintiff deadline in a class action lawsuit filed against TESARO Inc (NASDAQ: TSRO) (“TESARO” or “the Company”). The suit is pending in the U.S. District Court for the District of Massachusetts and investors, who purchased Tesaro Inc securities between March 14, 2016 and January 12, 2018, have until March 19, 2018 to move for lead plaintiff. You do not need to move for lead plaintiff to be a member of the Class.

If you purchased Tesaro Inc securities during the Class Period, and have losses over $100,000, you may contact Thieler Law Corp by calling at (619) 377 - 4324 or emailing mail@thielerlaw.com . No class has been certified in this case, and if your losses are less than $100,000 you are still a member of the class.

The complaint alleges that during the Class Period defendants made false and misleading statements and/or allegedly failed to disclose that substantial undisclosed health risks, including anaphylaxis and anaphylactic shock, were associated with TESARO's intravenous formulation of Varubi; and 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, Tesaro announced it had updated the U.S. labeling of VARUBI® (rolapitant) injectable emulsion packages after reports that some patients receiving the treatment experienced “Anaphylaxis, anaphylactic shock and other serious hypersensitivity reactions.”

Following this news, NASDAQ: TSRO fell $4.07 per share or over 5% to close at $65.52 per share on January 16, 2018.

If you were negatively impacted by your investment in Tesaro Inc securities between March 14, 2016 and January 12, 2018 and would like to learn more about this lawsuit and your ability to participate as a lead plaintiff, please contact us for your no-cost evaluation.
