Subject Company: TCR2 Therapeutics Inc.
(Commission File No. 001-38811)
Date: March 6, 2023
This filing relates to the proposed merger of TCR2 Therapeutics Inc., a Delaware corporation (the “Company”), with CM Merger Sub, Inc. (“Merger Sub”), a Delaware corporation and an indirect wholly-owned subsidiary of Adaptimmune Therapeutics plc (“Parent”) a public limited company incorporated in England and Wales, pursuant to the terms of that certain Agreement and Plan of Merger, dated as of March 5, 2023, by and among the Company, Merger Sub, and Parent (the “Merger Agreement”).
Dear TRuCers,
Today we announced a strategic combination with Adaptimmune Therapeutics aimed at creating a preeminent cell therapy company for solid tumors. This is an important development in the growth of TCR2. Combining with Adaptimmune will give us a stronger foundation to achieve our longstanding goal of bringing to cancer patients an innovative set of potentially curative therapies.
Like us, Adaptimmune is a leader in TCR-specific cell therapy, focused on designing and delivering novel cancer immunotherapy products. Their clinical pipeline is led by afami-cel for the treatment of people with synovial sarcoma and they are on track to submit a BLA by mid-year making it the first TCR therapy approvable for solid tumors. They also have a deep preclinical pipeline with multiple second generation autologous and allogeneic approaches backed by a proprietary TCR platform that is complementary to ours.
I want you all to know that a great deal of thought, analysis and consideration went into this decision. Our focus has always been on how best to advance gavo-cel and our other programs to as many cancer patients as possible. This is a beginning and not an end. In meeting with Adaptimmune, it was clear that they shared our vision and recognize the significant value we have been providing through our strong capabilities, team and culture. During the course of our discussions, we have discovered that Adaptimmune has a culture very similar to our own. The spirit of collaboration has been quite striking. I am confident that as partners we will reach even greater heights than we could have achieved on our own.
The combined company will have two advanced clinical franchises targeting MAGE-A4 and mesothelin. The preclinical pipeline will be anchored around PRAME and CD70. In addition, we will have a deep bench of cell therapy professionals, infrastructure and end-to-end capabilities that could be applied across an even broader portfolio of innovations with a cash runway anticipated to extend into 2026. As you know, focus and specialization are critical in the cell therapy space, and we believe the combined company will have the technologies and financial basis necessary to succeed in a very competitive and capital intensive space.
It is important to keep in mind that today is only the first step towards bringing our two companies together. In terms of next steps, we need to obtain shareholder approval and satisfy other closing conditions to complete the combination, which we currently expect to occur in the second quarter of 2023. Until then, TCR2 and Adaptimmune remain separate companies operating independently as we have done before. It is important to stay focused on our day-to-day roles and responsibilities so that we can continue to treat cancer patients with gavo-cel and TC-510. They depend on us.
Following the close of the transaction, the combined company will be led by Adrian Rawcliffe, the current CEO of Adaptimmune. Adrian is an industry veteran with over 20-years of experience in the biopharma industry, including at Adaptimmune and GSK, with a proven track record of driving innovation. You will get to meet him in person later in the week when he has finished his obligations at the Cowen Healthcare Conference. I know that he is excited to meet all of you.
Importantly, there will also be continued leadership from TCR2 in the combined company with the Board transferring three of our Directors, including myself, and several members of our leadership team expected to be announced at a later time. The combined company will have a significant presence in the key United States cell therapy and innovation hubs of Philadelphia, PA, and Cambridge, MA, as well as Oxford/Stevenage in the United Kingdom.
Change can be difficult and we have recently been through a lot of changes as an organization. I recognize that news like this will inevitably leave more questions than answers in the early stages of the transition period. As we have shown throughout our company’s history, we will treat all employees with due respect and be as transparent as possible during this process. I encourage you to listen to the webcast of the announcement, which can be accessed here, and join me at a Company Meeting scheduled for 11:45 AM ET. A meeting invitation for that will follow shortly. In the meantime, attached is an FAQ which I hope will address some initial questions. You will also have the opportunity for further dialog in group sessions and individual meetings with our leaders.
Today’s news may generate increased external interest in our company. Please direct any inquiries you receive from the media, analysts or investors to Eric Sullivan at eric.sullivan@tcr2.com. I also ask that you refrain from any personal social media posts at this time and restrict yourself to sharing corporate approved postings.
You are an incredible team and I am proud of all that we have accomplished together. It has been an amazing experience building this company over the last six years and providing gavo-cel and TC-510 to cancer patients. We now have an excellent opportunity to accelerate and enhance that work from a strong new foundation.
Thank you for your continued dedication and commitment to TCR2 and the cancer patients we serve.
Sincerely,
Garry (and the Executive Committee)
