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

Mar 22, 2022

CAMBRIDGE, Mass., March 22, 2022 (GLOBE NEWSWIRE) -- TCR2 Therapeutics Inc. (Nasdaq: TCRR), a clinical-stage cell therapy company with a pipeline of novel T cell therapies for cancer patients suffering from solid tumors, today announced financial results for the fourth quarter ended December 31, 2021 and provided a corporate update.

"Consistent execution throughout the last year has positioned TCR2 for a series of important readouts as we accelerate our clinical progress in 2022," said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR2 Therapeutics. "We were able to successfully conclude the dose escalation portion of our ongoing gavo-cel Phase 1/2 clinical trial with the identification of a RP2D and submit a protocol amendment with the FDA for the upcoming Phase 2 clinical trial. We also submitted an IND with the FDA for our first enhanced TRuC-T cell that incorporates a PD-1:CD28 switch. In the meantime, we have been identifying new clinical trial sites and expanding manufacturing capacity for the reproducible process used by Miltenyi and ElevateBio to support our clinical trials. In addition to the clinical readouts from gavo-cel and TC-510, we will continue to provide updates on the innovations in our rapidly growing pipeline, most immediately with a preclinical data presentation on our allogeneic TRuC targeting mesothelin at the AACR Annual Meeting in April."

Recent Developments


  • TCR2 announced the submission of a protocol amendment to the US Food and Drug Administration (FDA) in the first quarter of 2022 for the gavo-cel Phase 2 expansion cohort, including the amendment to treat patients with gavo-cel in combination with Opdivo and/or Yervoy which forms the basis of the Company’s clinical trial collaboration with Bristol Myers Squibb.


  • TCR2 announced the submission of an Investigational New Drug (IND) to the FDA in the first quarter of 2022 for TC-510, the Company’s first enhanced TRuC-T cell targeting mesothelin with a PD-1:CD28 chimeric switch receptor.


  • TCR2 announced it will present a poster at the American Association of Cancer Research (AACR) Annual Meeting 2022 featuring new preclinical data on an allogeneic (off-the-shelf) TRuC-T cell, taking place on April 8-13, 2022 in New Orleans, Louisiana. In preclinical studies, this allogeneic product candidate without an enhancement demonstrated improved anti-tumor efficacy associated with enhanced persistence and increased antigen sensitivity in vivo compared to donor-matched autologous TRuC-T cells targeting mesothelin. Furthermore, allogeneic TRuC-T cells generated with an additional knockout of Beta-2-microglobulin (B2M) maintained their potency.

  • TCR2 announced a strategic research collaboration agreement with Arbor Biotechnologies focused on the further development of a defined set of allogeneic TRuC-T cell therapies. The collaboration leverages Arbor's proprietary CRISPR gene-editing technology, which is tailored to address the underlying pathology of genetic diseases and TCR2's first-in-class TRuC platform, which has demonstrated clinical activity in multiple treatment-refractory mesothelin-expressing solid tumor indications with gavo-cel.


  • TCR2 announced the appointment of experienced biotech executive Rosemary Harrison, Ph.D., as Chief Business and Strategy Officer where she will be responsible for supporting a range of activities including commercial strategy, operational planning, corporate partnerships and long-term growth opportunities.

Anticipated Milestones

  • Gavo-cel:

    • Present the expanded and complete Phase 1 dataset for gavo-cel in the second quarter of 2022.

    • Initiate the Phase 2 expansion cohort of the ongoing gavo-cel Phase 1/2 clinical trial in the first half of 2022.

    • Provide an initial update from at least one of the Phase 2 expansion cohorts of the ongoing gavo-cel Phase 1/2 clinical trial in the second half of 2022.

  • TC-510:

    • Report initial safety, efficacy and translational data from at least one of the Phase 1 dose escalation cohorts of the TC-510 Phase 1/2 clinical trial in the second half of 2022.

  • Pipeline:

    • Initiate IND-enabling studies for TC-520, an enhanced CD70 targeting TRuC-T cell program, in 2022.

    • Select a lead candidate for its allogeneic program in 2022.

  • Manufacturing:

    • Production of clinical trial material to commence at ElevateBio BaseCamp as capacity is increased in anticipation of demand from the Phase 2 expansion trial of gavo-cel in 2022.

Financial Highlights

  • Cash Position: TCR2 ended the fourth quarter of 2021 with $265.6 million in cash, cash equivalents, and investments compared to $228.0 million as of December 31, 2020. Net cash used in operations was $23.3 million for the fourth quarter of 2021 compared to $13.5 million for the fourth quarter of 2020. TCR2 projects net cash use of $115-125 million for 2022. We expect cash on hand to support operations into 2024.
  • R&D Expenses: Research and development expenses were $22.4 million for the fourth quarter of 2021 compared to $14.3 million for the fourth quarter of 2020. The research and development expenses for the fourth quarter of 2021 include restructuring costs of $3.7 million and are partially offset by a $2 million settlement from a vendor due to a commercial dispute. The remaining increase in R&D expenses was primarily due to an increase in headcount and manufacturing facilities.
  • G&A Expenses: General and administrative expenses were $5.2 million for the fourth quarter of 2021 compared to $4.3 million for the fourth quarter of 2020. The increase in general and administrative expenses was primarily due to an increase in personnel costs.
  • Net Loss: Net loss was $27.7 million for the fourth quarter of 2021 compared to $18.5 million for the fourth quarter of 2020.
