Item 8.01 – Other Events.
As previously announced, on September 20, 2022, Sesen Bio, Inc., a Delaware corporation (“Sesen Bio”), entered into a definitive merger agreement with CARISMA Therapeutics Inc., a Delaware corporation (“Carisma”), pursuant to which a wholly-owned subsidiary of Sesen Bio will merge with and into Carisma (the “merger”), with Carisma surviving as a wholly-owned subsidiary of Sesen Bio. The merger is currently expected to close in the next one to two months, subject to approval by Sesen Bio’s stockholders and other customary closing conditions.
On December 12, 2022, Carisma posted an updated corporate presentation on its website, which is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference. Among other items, the primary updates to Carisma’s corporate presentation include updated interim data for Study 101 of Carisma’s lead asset CT-0508, which further supports the safety profile and tumor infiltration observed by Carisma to date, and an updated timeline for Carisma’s anticipated value inflection points over the next 18 months, including six pre-clinical and clinical development milestones Carisma expects in 2023.
