TCR² Therapeutics Reports First Quarter 2021 Financial Results and Provides Corporate Update

Cambridge, Massachusetts, UNITED STATES

CAMBRIDGE, Mass., May 13, 2021 (GLOBE NEWSWIRE) -- TCR2 Therapeutics Inc. (Nasdaq: TCRR), a clinical-stage cell therapy company with a pipeline of novel T cell therapies for patients suffering from cancer, today announced financial results for the first quarter ended March 31, 2021 and provided a corporate update. 

“We remain on track to identify the recommended Phase 2 dose for gavo-cel in 2021 and advance into the expansion portion of the Phase 1/2 trial where our primary focus will be efficacy as well as continuing to monitor for safety. The clinical benefit we have observed with our cancer patients gave us confidence to expand our manufacturing capabilities by establishing a commercial-scale cGMP facility in Rockville, Maryland, which we expect to come online in 2023,” said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR2 Therapeutics. “In the last quarter we were also able to showcase our early-stage programs in our rich pipeline and reflect on the versatility of our TRuC-T cell platform. This included presenting our CD70-targeted autologous TRuC-T cell and our mesothelin-targeted allogeneic TRuC-T cell at AACR. As for our additional solid tumor milestones in 2021, we expect to present more complete data from the dose escalation Phase 1 portion of the gavo-cel trial, file an IND for TC-510, a mesothelin-targeted TRuC-T cell enhanced with a PD-1:CD28 switch receptor, and present preclinical data on our IL-15 enhancement, which we believe will drive even longer persistence and expression of a memory phenotype, characteristics which could be beneficial across our portfolio.”

Recent Developments


  • TCR2 presented clinical and translational data from the dose escalation portion of the Company’s Phase 1/2 clinical trial of gavo-cel in patients with treatment refractory mesothelin-expressing solid tumors at the American Association for Cancer Research (AACR) Virtual Annual Meeting. The data reported were from eight treatment-refractory mesothelin-expressing solid tumor patients and highlighted translational markers consistent with the clinical profile, including transduction efficiency, CD4:CD8 ratio, memory phenotype, expansion and persistence and cytokines.

Early-Stage Pipeline

  • TCR2 presented new preclinical data from its allogeneic “off the shelf” TRuC-T cell targeting mesothelin highlighting a lack of alloreactivity, reduced risk of host rejection, upregulation of activation markers, secretion of cytokines and clearance of tumors comparable to gavo-cel at the AACR Virtual Annual Meeting.
  • TCR2 presented new preclinical data from its TRuC-T cell targeting CD70 highlighting T cell expansion, improved memory phenotype, significant anti-tumor efficacy in multiple xenograft mouse models with no evidence of in vivo fratricide at the AACR Virtual Annual Meeting.


  • TCR2 announced that it signed a long-term, full-building lease with Alexandria Real Estate Equities, Inc. (NYSE: ARE) for an existing 85,000 square foot cell therapy manufacturing facility in Rockville, Maryland which is ready for Current Good Manufacturing Practice (cGMP) build-out. The site will support clinical and commercial production of gavo-cel with a capacity that is projected to treat several thousand cancer patients annually. The facility is expected to accelerate the Company’s commercial-scale manufacturing timelines with production anticipated in 2023.
  • TCR2 announced the appointment of Aaron Vernon as Vice President of Technical Operations. Previously, Mr. Vernon held senior positions including Vice President of Global Technical Operations and Vice President of Engineering & Supply Chain at Autolus Therapeutics, where he led manufacturing capacity expansion and overseeing internal and external manufacturing of plasmid, vector and cell therapy products.

Anticipated Milestones

  • TCR2 to present additional safety, efficacy and translational data from the Phase 1 portion of the gavo-cel Phase 1/2 clinical trial for patients with mesothelin-expressing solid tumors throughout 2021.
  • TCR2 to present 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 the second half of 2021.
  • TCR2 plans to file an IND for TC-510, the first enhanced TRuC-T cell targeting mesothelin with a PD-1:CD28 switch, in the second half of 2021.
  • TCR2 plans to select a development candidate for its allogeneic program in the second half of 2021.
  • TCR2 to present preclinical data on its IL-15 enhancements program in the second half of 2021.
  • TCR2 anticipates production of clinical trial material from ElevateBio LLC and its manufacturing facility in Stevenage, UK, both in anticipation of demand from the Phase 2 expansion trial of gavo-cel, in 2022.

Financial Highlights

  • Cash Position: TCR2 ended the first quarter of 2021 with $333.3 million in cash, cash equivalents, and investments compared to $228.0 million as of December 31, 2020. Net cash used in operations was $19.9 million for the first quarter of 2021 compared to $16.4 million for the first quarter of 2020. TCR2 projects net cash use of $100-110 million for 2021, which includes tenant improvements to the Rockville facility. We expect cash on hand to support operations through 2023.

  • R&D Expenses: Research and development expenses were $15.9 million for the first quarter of 2021 compared to $12.0 million for the first quarter of 2020. The increase in R&D expenses is primarily related to ongoing clinical trials, increase in headcount and additional lab facilities.

  • G&A Expenses: General and administrative expenses were $5.7 million for the first quarter of 2021 compared to $4.3 million for the first quarter of 2020. The increase in general and administrative expenses was primarily due to an increase in personnel costs.

  • Net Loss: Net loss was $21.5 million for the first quarter of 2021 compared to $15.5 million for the first quarter of 2020, driven predominantly by increased personnel expenses.

Rockville Facility

In March 2021, we entered into a lease for a new manufacturing facility. The landlord built an approximately 85,000 square foot rental building in Rockville, Maryland and leased the facility to the Company as a manufacturing facility for an initial term of 15 years through June 2036.

Because we are involved in the construction project and are responsible for paying a significant portion of the costs of normal finish work and structural elements of the facility, the Company is deemed for accounting purposes to be the owner of the building during the construction period under build to suit lease accounting guidance under ASC 840, Leases. Therefore, the Company recorded a construction-in-progress asset and a related construction financing obligation on our consolidated balance sheets as a component of property and equipment and lease financing obligations, respectively. We anticipate lease payments of $1.4 million for the remainder of 2021.

About TCR2 Therapeutics

TCR2 Therapeutics Inc. is a clinical-stage cell therapy 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, gavo-cel, 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).
