There is no cost or obligation to you.

Faruqi & Faruqi is a leading minority and Woman-owned national securities law firm with offices in New York, Delaware, Pennsylvania, California and Georgia.

As detailed below, the lawsuit focuses on whether the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose: (1) that Sesen Bio's clinical trial for Vicineum had more than 2,000 violations of trial protocol, including 215 classified as "major"; (2) that three of Sesen Bio's clinical investigators were found guilty of "serious noncompliance," including "back-dating data"; (3) that Sesen Bio had submitted the tainted data in connection with the BLA for Vicineum; (4) that 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; and (5) that, 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.

On August 18, 2021, before the market opened, STAT published an article entitled "Sesen Bio trial of cancer drug marked by misconduct and worrisome side effects, documents show." Citing "hundreds of pages of internal documents" and "three people familiar with the matter," the article detailed that the clinical trial for Vicineum was "marked by thousands of violations of study rules, damning investigator conduct, and worrying signs of toxicity the company did not publicly disclose."

The STAT article further stated that Vicineum had led to "worrisome side effects," including "a serious risk for fatal, drug-induced liver injury."

On this news, the Company's share price fell $0.20, or 13%, to close at $1.31 per share on August 18, 2021, on unusually heavy trading volume.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not.

Faruqi & Faruqi, LLP also encourages anyone with information regarding Sesen's conduct to contact the firm, including whistleblowers, former employees, shareholders and others.
