Item 8.01 – Other Events.

On March 30, 2021, Sesen Bio, Inc. (the “Company”) provided a regulatory update for Vicineum™ for the four largest global markets in terms of commercial opportunity for the treatment of BCG-unresponsive non-muscle invasive bladder cancer (“NMIBC”):

United States:
The Company will be participating in a Late-Cycle Meeting with the U.S. Food and Drug Administration (“FDA”) to discuss the Biologics License Application (“BLA”) for Vicineum on June 1, 2021. The Late-Cycle Meeting will be held between members of the FDA review team and the Company to discuss the status of the review and is intended to share information and plan for the rest of the review.

In February 2021, the Company received notice from the FDA that the BLA for Vicineum was accepted for filing and granted Priority Review with a target Prescription Drug User Fee Act (“PDUFA”) date of August 18, 2021 for a decision on the BLA.

Europe:
The Company received notice on March 25, 2021 from the European Medicines Agency (“EMA”) that the Company’s Marketing Authorization Application (“MAA”) for Vicineum was found to be valid and that the review procedure has officially started. The Company remains on-track for potential approval of Vicineum in Europe in early 2022. Additionally, the Company has completed the tradename approval process with the EMA1 and anticipates an official decision on the proprietary brand name in Europe from the EMA in the next few weeks.

China:
The Company received notice on March 19, 2021 from its partner, Qilu Pharmaceutical, that the Investigational New Drug (“IND”) application for Vicineum for the treatment of BCG-unresponsive NMIBC submitted to the Center for Drug Evaluation (“CDE”) of the China National Medical Products Administration (“NMPA”) was approved, thereby triggering a $3M milestone payment to the Company.

With approval of the IND, Qilu Pharmaceutical is authorized to conduct the proposed clinical trial to assess the efficacy and safety of Vicineum in patients with BCG-unresponsive NMIBC in China, at the sole cost of Qilu Pharmaceutical with the first patient enrolled in the trial expected in the next one-to-two months. Assuming a successful trial, Qilu Pharmaceutical anticipates submission of the product market application for Vicineum in 2022 with potential approval in China expected in 2023.

Middle East and North Africa (“MENA”):
The Company continues to work closely with its partner, Hikma Pharmaceuticals, to submit marketing authorization applications for Vicineum in 2021 in four key markets in the region: the Kingdom of Saudi Arabia, Jordan, Morocco and Egypt. These four markets represent a significant opportunity in the MENA region, as Saudi Arabia, Jordan and Morocco have some of the most advanced healthcare systems in the region while Egypt is the second largest economy in Africa. The Company anticipates the first wave of potential country approvals for Vicineum in the MENA region as early as 2022.

______________

1The proprietary brand name, Vicineum is a corporate trademark which has been conditionally approved by the FDA. Final approval of the Vicineum brand name is conditional on FDA approval of the Company’s product candidate, oportuzumab monatox. The Company is currently awaiting a tradename decision from the EMA for oportuzumab monatox.
