Sesen Bio, Inc. Loss Submission Form

The Law Offices of Vincent Wong announce that a class action lawsuit has been commenced in the United States District Court for the Southern District of New York on behalf of investors who purchased Sesen Bio, Inc. (NASDAQ: SESN) securities between December 21, 2020 and August 17, 2021.

According to the Sesen Bio lawsuit, throughout the Class Period defendants made false and/or misleading statements and/or failed to disclose that: (1) Sesen Bio’s clinical trial for its cancer treatment product, Vicineum, had more than 2,000 violations of trial protocol, including 215 classified as “major”; (2) three of Sesen Bio’s clinical investigators were found guilty of “serious noncompliance,” including “back-dating data”; (3) Sesen Bio had submitted the tainted data in connection with the Biologics License Application (“BLA”) for Vicineum; (4) Sesen Bio’s clinical trials showed that Vicineum leaked out into the body, leading to side effects including liver failure and liver toxicity, and increasing the risks for fatal, drug-induced liver injury; (5) as a result of the foregoing, the Company’s BLA for Vicineum was not likely to be approved; (6) as a result of the foregoing, there was a reasonable likelihood that Sesen Bio would be required to conduct additional trials to support the efficacy and safety of Vicineum; and (7) as a result of the foregoing, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

If you suffered a loss in Sesen Bio you have until October 18, 2021 to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn\'t require that you serve as a lead plaintiff.
