Item 7.01 – Regulation FD Disclosure.

On January 7, 2022, the US Food & Drug Administration (“FDA”) granted Sesen Bio, Inc.’s (the “Company”) request for a Type C meeting (“Type C Meeting”) to discuss the study protocol for an additional Phase 3 clinical trial that the Company plans to conduct for potential resubmission of its Biologics License Application (“BLA”) for Vicineum™ for the treatment of BCG-unresponsive non-muscle invasive bladder cancer (“NMIBC”).

The Type C Meeting has been scheduled for March 28, 2022. The Company plans to provide additional information at that time.

The information furnished in this Item 7.01 shall not be deemed to be “filed” for the purposes of Section 18 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of such section, nor shall such information be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS:

This Current Report on Form 8-K contains forward-looking statements, including, but not limited to, statements regarding the Company’s plans to conduct an additional Phase 3 clinical trial for potential resubmission of its BLA for Vicineum and the Company’s plans to provide additional information at the time of the Type C Meeting. The Company’s actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of these risks and uncertainties, including the risk that the Type C Meeting may not occur within the anticipated timing, or at all, the risk that the Type C Meeting may not enable the Company align with the FDA on the protocol for an additional Phase 3 clinical trial of Vicineum for the treatment of BCG-unresponsive NMIBC, the risk that the Company may not resume its plans to pursue regulatory approval for Vicineum for the treatment of BCG-unresponsive NMIBC in the US, the risk that the additional Phase 3 clinical trial of Vicineum for the treatment of BCG-unresponsive NMIBC may fail to demonstrate safety and efficacy to the satisfaction of the FDA, or otherwise produce favorable results, the risk that the FDA may not approve the BLA for Vicineum for the treatment of BCG-unresponsive NMIBC if the Company resubmits the BLA at a future time and the risk that Vicineum for the treatment of BCG-unresponsive NMIBC may cause undesirable side effects, serious adverse events or have other properties that could delay or halt clinical trials, delay or prevent its regulatory approval by the FDA, limit the commercial profile of its labeling, if approved, or result in significant negative consequences following any marketing approval, among other risks and uncertainties. A further description of the risks and uncertainties relating to the business of the Company is contained in the Company’s most recent annual report on Form 10-K and the Company’s quarterly reports on Form 10-Q, as well as any amendments thereto reflected in subsequent filings with the Securities and Exchange Commission. The Company undertakes no duty or obligation to update any forward-looking statements contained in this report as a result of new information, future events or changes in its expectations.
