CAMBRIDGE, Mass., Nov. 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 third quarter ended September 30, 2020 and provided a corporate update.

“The third quarter was marked by consistency in the clinical benefit provided by our lead TRuC-T cell program, TC-210, previously shown to have produced RECIST partial responses at its very first dose level, as well as the completion of a successful financing,” said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR² Therapeutics. “As we prepare for the expansion portion of the TC-210 trial, we are excited to bring on additional clinical sites to increase patient recruitment and we have also launched a strategic partnership with ElevateBio, whose state-of-the-art manufacturing center will support the Phase 2 clinical trial of TC-210 and planned investigator-initiated studies. We look forward to providing a clinical data update on TC-210 in the fourth quarter.”

Recent Developments

• TCR² announced a partnership with ElevateBio, LLC, a Cambridge, MA-based creator and operator of a portfolio of innovative cell and gene therapy companies. The agreement with ElevateBio provides TCR² access to ElevateBio BaseCamp, its centralized 140,000 square foot, world-class cell and gene therapy manufacturing facility based in Waltham, MA. The BaseCamp partnership enables TCR² Therapeutics to establish additional manufacturing capacity and technical capabilities in the U.S., in addition to its existing Stevenage, UK, manufacturing facility, and will support the Phase 2 expansion portion of the TC-210 Phase 1/2 clinical trial once a recommended Phase 2 dose is defined.
  

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 4Q20.
• 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 2021.
• TCR² anticipates certification of its manufacturing facility in Stevenage, UK, in 4Q20.
• TCR² anticipates an IND filing for a third TRuC-T cell program in 2021.

Financial Highlights

• Cash Position: TCR² ended the third quarter of 2020 with $246.7 million in cash, cash equivalents, and investments compared to $158.1 million as of December 31, 2019. Net cash used in operations was $10.8 million for the third quarter of 2020 compared to $10.1 million for third quarter of 2019. TCR² projects net cash use of $65-70 million for 2020.
  
  
• R&D Expenses: Research and development expenses were $12.8 million for the third quarter of 2020 compared to $11.3 million for the third quarter of 2019. The increase in R&D expenses were primarily related to increases 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 $4.4 million for the third quarter of 2020 compared to $3.5 million for the third 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 $16.9 million for the third quarter of 2020 compared to $13.8 million for the third quarter of 2019, driven predominantly by increased personnel 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).
