Sesen Bio is an advanced stage clinical company claiming to advance targeted fusion protein (“TFP”) therapies for cancer treatments. Its most advanced product candidate is Vicineum (VB4-845), a topically administered PTF developed for the treatment of unresponsive Calmette-Guérin bacillus (“BCG”) -muscular non-invasive bladder cancer (“NMIBC”). Sesen Bio has published preliminary data on the efficacy of its ongoing Phase 3 clinical trial for Vicineum, the VISTA trial, in August 2019.
At December 21, 2020, the Company announced that it has submitted its biologic license application (“BLA”) to the United States Food and Drug Administration (“FDA”) for Vicineum for the treatment of NMIBCs not responding to BCG.
The complaint alleges that, throughout the Class Period, the Defendants made materially false and / or misleading statements, and failed to disclose material adverse facts regarding the business, operations and prospects of the Company. Specifically, the Defendants failed to disclose to investors: (1) that the clinical trial of Sesen Bio for Vicineum contained more than 2,000 trial protocol violations, of which 215 were classified as “major”; (2) that three of Sesen Bio’s clinical investigators were convicted of “serious non-compliance”, including “backdated data”; (3) that Sesen Bio had submitted flawed data related to the BLA for Vicineum; (4) that clinical trials of Sesen Bio have shown that Vicineum has entered the body causing side effects, including liver failure and liver toxicity, and increasing the risk of fatal drug-induced liver damage; (5) that due to the above, the Company’s BLA for Vicineum was not likely to be approved; (6) that due to the foregoing, there was a reasonable likelihood that Sesen Bio would be required to conduct additional trials to substantiate the efficacy and safety of Vicineum; and (7) that as a result of the foregoing, the Defendants’ positive statements regarding the activities, operations and prospects of the Company were substantially misleading and / or lacked reasonable basis.
At August 13, 2021, Sesen Bio has announced that the FDA has refused to approve its BLA for Vicineum in its current form.
