The complaint alleges that, throughout the Class Period, Defendants made false and misleading statements and failed to disclose that: (i) that Sesen Bio’s clinical trial for Vicineum had more than 2,000 violations of trial protocol, including 215 classified as ‘major’; (ii) that three of Sesen Bio’s clinical investigators were found guilty of ‘serious noncompliance,’ including ‘back-dating data’; (iii) that Sesen Bio submitted the tainted data in connection with the BLA for Vicineum (iv) that Sesen Bio’s clinical trials showed that Vicineum leaked out into the body, leading to sides effects including liver failure and liver toxicity, and increasing the risks for fatal, drug-induced liver injury; (v) that, as a result of the foregoing, the Company’s BLA for Vicineum was not likely to be approved; (vi) that, 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 (vii) 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 13, 2021, Sesen Bio announced the FDA declined to approve its Biologics License Application for Vicineum in its current form. On this news, the Company’s share price fell $2.80, or 57%, to close at $2.11 per share on August 13, 2021.
On August 16, 2021, Sesen Bio further revealed that “it appears that [the Company] will need to do a clinical trial to provide the additional efficacy and safety data necessary for the FDA to assess the benefit-risk profile, which is the basis for approval.” The Company announced it expected it could not resubmit its BLA until 2023. On this news, the Company’s share price fell $0.89, or 42%, to close at $1.22 per share on August 16, 2021.
Then, on August 18, 2021, the health and medicine news site STAT published an article entitled “Sesen Bio trial of cancer drug marked by misconduct and worrisome side effects, documents show.” 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. On this news, the Company’s share price fell $0.20, or 13% to close at $1.31 per share on August 18, 2021.
