TCR² Therapeutics Reports Second Quarter 2020 Financial Results and Provides Corporate Update


- TC-210 patient with partial response confirmed by independent central review and tumor regression improved further from 42% to 75%

- Began dosing of TC-110 in the Phase 1/2 trial for patients with CD19+ NHL or adult ALL

- Addition of MD Anderson Cancer Center, a leading clinical site, to the TC-110 Phase 1/2 clinical trial

- Raised gross proceeds of $142.6 million in a secondary offering in July; extended cash runway into 2023

CAMBRIDGE, Mass., Aug. 12, 2020 (GLOBE NEWSWIRE) -- TCR2 Therapeutics Inc. (Nasdaq: TCRR), a clinical-stage immunotherapy company with a pipeline of novel T cell therapies for patients suffering from cancer, today announced financial results for the second quarter ended June 30, 2020 and provided a corporate update.

“The second quarter was incredibly strong for the Company as we continued to deliver significant progress in our clinical trials of TC-210 and TC-110 despite the pandemic. We are particularly pleased to update that, following the earlier announcement of five of our first five cancer patients showing tumor regression with TC-210, one patient is now a confirmed partial response based on independent central review and experienced further tumor regression from 42% to 75%,” said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR2 Therapeutics. “The initial data from TC-210 provide meaningful readthrough for our TRuC-T cell platform and we believe our robust preclinical pipeline supports our next phase of growth as we build a leading cell therapy company treating solid tumors. The strengthening of our balance sheet through our recent financing puts us in an excellent position to execute on our objectives and provide further clinical and scientific updates in 2020.”

Recent Developments

  • TCR2 announced positive interim data from the first five patients treated in the Phase 1 portion of the TC-210 Phase 1/2 clinical trial for mesothelin-expressing solid tumors. All five patients showed tumor regression including two with RECIST partial response, one of which is now confirmed and two patients with stable disease through six months. Translational data further demonstrated TRuC-T cell expansion and activation. A manageable toxicity profile was observed with only one patient exhibiting TC-210-related non-hematologic grade >2 toxicity and no evidence of neurotoxicity or on-target, off-tumor toxicity.
  • TCR2 highlighted preclinical data at the American Association for Cancer Research (AACR) Virtual Annual Meeting II of the Company’s proprietary T Cell Receptor Fusion Construct (TRuC®) T cells that co-express a PD-1:CD28 switch receptor, which acts as a cell-intrinsic mechanism to overcome PD-L1/PD-L2 mediated immunosuppression. Upon repeated antigen stimulation, co-expression of the switch receptor in mesothelin-targeting TC-210 T cells enhanced TCR downstream signaling, prevented PD-L1-mediatied functional T-cell inhibition, significantly increased proliferation and augmented the production of growth and effector cytokines.
  • TCR2 announced the expansion of its leadership team with key business development and regulatory affairs cell therapy experts with the appointments of Gregg McConnell as Head of Business Development and Viera Muzithras as Vice President of Regulatory Affairs.

Anticipated Milestones

  • TCR2 anticipates an interim update from the Phase 1 portion of the TC-210 Phase 1/2 clinical trial for patients with mesothelin-expressing solid tumors in 2H20.
  • TCR2 anticipates an interim update from the Phase 1 portion of the TC-110 Phase 1/2 clinical trial for patients with CD19+ non-Hodgkin lymphoma or adult acute lymphoblastic leukemia in 2H20.
  • TCR2 anticipates certification of its manufacturing facility in Stevenage, UK, in 2H20.
  • TCR2 anticipates an IND filing for a third TRuC-T cell program in 2021.

Financial Highlights

  • Cash Position: TCR2 ended the second quarter of 2020 with $124.8 million in cash, cash equivalents, and investments compared to $158.1 million as of December 31, 2019. As a result of the recent equity offering, TCR2 raised an additional $134.6 million. Net cash used in operations was $16.0 million for the second quarter of 2020 compared to $10.2 million for second quarter of 2019. TCR2 continues to project net cash use of $60-70 million for 2020.
     
  • R&D Expenses: Research and development expenses were $12.9 million for the second quarter of 2020 compared to $8.8 million for the second quarter of 2019. The increase in R&D expenses is primarily related to increase in headcount, activities related to the Phase 1/2 clinical trial of TC-210 and activities related to the Phase 1/2 clinical trial of TC-110.
     
  • G&A Expenses: General and administrative expenses were $3.8 million for the second quarter of 2020 compared to $3.3 million for the second quarter of 2019. The increase in general and administrative expenses was primarily due to an increase in personnel costs and costs associated with operations as a public company.
     
  • Net Loss: Net loss was $16.2 million for the second quarter of 2020 compared to $11.1 million for the second quarter of 2019, driven predominantly by increased R&D expenses.

About TCR2 Therapeutics

TCR2 Therapeutics Inc. is a clinical-stage immunotherapy company developing a pipeline of novel T cell therapies for patients suffering from solid tumors or hematological malignancies. TCR2’s proprietary T cell receptor (TCR) Fusion Construct T cells (TRuC®-T cells) specifically recognize and kill cancer cells by harnessing signaling from the entire TCR, independent of human leukocyte antigens (HLA). In preclinical studies, TRuC-T cells have demonstrated superior anti-tumor activity compared to chimeric antigen receptor T cells (CAR-T cells), while secreting lower levels of cytokine release. The Company’s lead TRuC-T cell product candidate targeting solid tumors, TC-210, is currently being studied in a Phase 1/2 clinical trial to treat patients with mesothelin-positive non-small cell lung cancer (NSCLC), ovarian cancer, malignant pleural/peritoneal mesothelioma, and cholangiocarcinoma. The Company’s lead TRuC-T cell product candidate targeting hematological malignancies, TC-110, is currently being studied in a Phase 1/2 clinical trial to treat patients with CD19-positive adult acute lymphoblastic leukemia (aALL) and with aggressive or indolent non-Hodgkin lymphoma (NHL).
