A new approach to drugging a difficult cancer target

Phys.org | March 15, 2019

One of the most common cancer-promoting genes, known as Myc, is also one of the most difficult to target with drugs. Scientists have long tried to develop drugs that block the Myc protein, but so far their efforts have not been successful. Now, using an alternative strategy, MIT researchers have discovered a compound that can reduce Myc activity by tying up the protein that is Myc's usual binding partner, leaving Myc partnerless and unable to perform its usual functions. The research team, led by Angela Koehler, an assistant professor of biological engineering and a member of MIT's Koch Institute for Integrative Cancer Research, found that the compound they developed could suppress tumor growth in mice with certain types of cancer. The compound has been licensed by an MIT spinout that is now seeking to develop more powerful versions that could potentially be tested in human patients.

Sesen Bio and Carisma Therapeutics Announce Merger Agreement

Sesen Bio and Carisma Therapeutics | September 22, 2022

Sesen Bio, Inc. and Carisma Therapeutics Inc. a privately held, clinical stage biopharmaceutical company focused on discovering and developing innovative immunotherapies, announced that they have entered into a definitive merger agreement to combine the companies in an all-stock transaction. The combined company will focus on the advancement of Carisma’s proprietary cell therapy platform that utilizes engineered macrophages and monocytes to potentially transform the treatment of cancer and other serious disorders. Carisma is pioneering the development of chimeric antigen receptor macrophage therapies and is believed to be the only company developing CAR-M therapies with demonstrated proof of mechanism and safety data in clinical trials. The combined company is expected to operate under the name Carisma Therapeutics Inc. and trade on Nasdaq under the ticker symbol “CARM”. Carisma has also secured commitments from a syndicate of investors for a $30 million financing, including HealthCap, AbbVie, Wellington Partners, SymBiosis, Penn Medicine, TPG Biotech, MRL Ventures Fund, the therapeutics-focused corporate venture arm of Merck & Co., Agent Capital, Solasta, Livzon, Pictet Alternative Advisors and 4Bio, which is expected to close concurrently with the completion of the merger. With the cash expected from both companies at closing and the proceeds of the concurrent financing, the combined company is expected to have approximately $180 million in cash, cash equivalents and marketable securities. These cash resources are expected to be used to advance Carisma’s pipeline through multiple ongoing and planned key data readouts across several clinical trials and to fund operating expenses and capital expenditure requirements through 2024. The merger and related financing are expected to close in the next three to four months. “The proposed merger represents an exciting opportunity for shareholders of each company, and we believe it gets us one step closer to our goal of revolutionizing the field of immunotherapy. This transaction will provide us with financial strength to not only continue to develop our lead candidate CT-0508, but also allow us to accelerate the growth of our platform and pipeline within and outside of oncology and develop additional strong strategic partnerships beyond those we already have with Moderna and Novartis. Carisma is focused on delivering cutting-edge technology for patients in a way that has never been done before, and we look forward to advancing this important mission.” Steven Kelly, President and Chief Executive Officer of Carisma “This transaction represents the result of a thoughtful and careful review of strategic alternatives over the past four months, during which Carisma’s clinical programs, management team, and corporate strategy stood out amongst the 42 bids reviewed,” said Dr. Thomas Cannell, President and Chief Executive Officer of Sesen Bio. “Carisma is an exciting clinical-stage company with groundbreaking science and an impressive management team, which we believe makes them the optimal partner to provide value for our shareholders. Our mission at Sesen Bio has always been to save and improve the lives of patients with cancer, and we believe Carisma has the science and the unwavering patient focus required to make that mission a reality.” About the Proposed Merger Pre-merger Sesen Bio stockholders are expected to own approximately 41.7% and pre-merger Carisma stockholders are expected to own approximately 58.3% of the combined company, in each case before giving effect to the concurrent financing described above and the conversion of the outstanding Moderna convertible note. Under the terms of the merger agreement, stockholders of Carisma will receive newly issued shares of Sesen Bio common stock pursuant to an exchange ratio formula set forth in the merger agreement. The percentage of the combined company that Sesen Bio stockholders will own upon the closing of the merger is further subject to adjustment based on the amount of Sesen Bio’s net cash at the time of closing. Immediately prior to the closing of the proposed merger, Sesen Bio stockholders of record will be issued a contingent value right (CVR) for each outstanding share of Sesen Bio common stock held by such Sesen Bio stockholder as of such date, representing the right to receive certain cash payments from proceeds received by Sesen Bio related to the Roche Asset Purchase Agreement, if any, subject to customary deductions, including for expenses and taxes. SVB Securities is acting as exclusive financial advisor to Sesen Bio for the transaction and Hogan Lovells US LLP is serving as its legal counsel. Evercore Group LLC is serving as lead financial advisor to Carisma for the transaction and BofA Securities, Inc. is also serving as financial advisor to Carisma for the transaction. Wilmer Cutler Pickering Hale and Dorr LLP is serving as legal counsel to Carisma. BofA Securities, Inc. and Evercore Group L.L.C. are serving as co-placement agents for Carisma’s concurrent financing and Shearman & Sterling LLP is serving as the placement agents’ legal counsel. About Sesen Bio Sesen Bio, Inc. is a late-stage clinical company focused on targeted fusion protein therapeutics for the treatment of patients with cancer. Sesen Bio’s most advanced product candidate, Vicineum™, also known as VB4-845, is a locally-administered targeted fusion protein composed of an anti-epithelial cell adhesion molecule antibody fragment tethered to a truncated form of Pseudomonas exotoxin A for the treatment of non-muscle invasive bladder cancer. On July 15, 2022, Sesen Bio made the strategic decision to voluntarily pause further development of Vicineum in the US. The decision was based on a thorough reassessment of Vicineum, which included the incremental development timeline and associated costs for an additional Phase 3 clinical trial, following Sesen Bio’s discussions with the United States Food and Drug Administration. Sesen Bio has turned its primary focus to assessing potential strategic alternatives with the goal of maximizing shareholder value. Additionally, Sesen Bio intends to seek a partner for the further development of Vicineum. About Carisma Therapeutics Carisma Therapeutics Inc. is a biopharmaceutical company dedicated to developing a differentiated and proprietary cell therapy platform focused on engineered macrophages, cells that play a crucial role in both the innate and adaptive immune response. The first applications of the platform, developed in collaboration with the University of Pennsylvania*, are autologous chimeric antigen receptor (CAR)-macrophages for the treatment of solid tumors. Carisma Therapeutics is headquartered in Philadelphia, PA.
