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

Nov 10, 2021

CAMBRIDGE, Mass., Nov. 10, 2021 (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 third quarter ended September 30, 2021 and provided a corporate update.

“Over the last few months, we continue to treat cancer patients in our ongoing gavo-cel Phase 1 clinical trial and have observed meaningful clinical benefit in three different treatment-refractory solid tumor indications,” said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR2 Therapeutics. “As we prepare for the phase 2 trial to be launched in early 2022, we are expanding our US manufacturing footprint and successfully negotiated a clinical trial collaboration agreement with Bristol Myers Squibb, where we will have the opportunity to evaluate the efficacy and duration of gavo-cel in combination with Opdivo and Yervoy. We anticipate selecting the RP2D before year end and look forward to providing an update on gavo-cel in 1Q22 following review by the US Food and Drug Administration.”

Recent Developments

Gavo-cel:

  • TCR2 announced positive interim data from the first 17 patients treated in the Phase 1 portion of the gavo-cel Phase 1/2 clinical trial for mesothelin-expressing solid tumors. 15 of the 16 patients evaluable for efficacy experienced regression of their target lesions including 6 patients that achieved a partial response (PR) by target lesion assessment, 4 of whom met criteria for a PR according to RECIST 1.1 criteria. The maximum tolerated dose (MTD) was declared 5x108/m2after lymphodepletion.
  • Following identification of the MTD, TCR2 announced the completion of the 3-patient cohort at the new dose level 3.5A (3x108/m2 following lymphodepletion) using a split dosing approach. Two patients were evaluable for safety. In both cases, gavo-cel was well-tolerated with no patients experiencing Grade ≥3 cytokine release syndrome (CRS).
  • TCR2 announced a clinical trial collaboration agreement with Bristol Myers Squibb (NYSE: BMY) to evaluate gavo-cel in combination with Opdivo® (nivolumab) and Yervoy® (ipilimumab) in its planned Phase 2 clinical trial in treatment refractory mesothelin-expressing solid tumors.

Corporate:

  • TCR2 announced at its virtual R&D Day on October 20, 2021, its pipeline prioritization of solid tumors and highlighted programs from its emerging TRuC pipeline including TC-510, its first TRuC-T cell enhanced with a PD1xCD28 switch receptor; TC-520, its lead candidate targeting CD70 expressing an IL-15 enhancement; allogeneic TRuC-T cells; and TRuC Tregs, the first utilization of the TRuC platform in the autoimmune setting.
  • TCR2 announced the expansion of its manufacturing capacity by exercising an option on a second clean room at ElevateBio BaseCamp which adds to the buildout of clinical and commercial supply currently underway at its Rockville, MD facility. In connection with this expansion, TCR2 proposes to cease manufacturing activities at the Cell and Gene Therapy Catapult (CGT Catapult) in Stevenage, UK.

Anticipated Milestones

  • TCR2 anticipates the identification of the recommended Phase 2 dose (RP2D) in 4Q21.
  • TCR2 plans to file an IND for TC-510, the first enhanced TRuC-T cell (targeting mesothelin with a PD1xCD28 switch), in the first quarter of 2022.
  • TCR2 anticipates initiation of IND-enabling studies for TC-520, an enhanced CD70 targeting TRuC-T cell program in 2022.
  • TCR2 plans to select a lead candidate for its allogeneic program in 2022.
  • TCR2 anticipates production of clinical trial material from ElevateBio BaseCamp in anticipation of demand from the Phase 2 expansion trial of gavo-cel in 2022.

Financial Highlights

  • Cash Position: TCR2 ended the third quarter of 2021 with $295.7 million in cash, cash equivalents, and investments compared to $228.0 million as of December 31, 2020. Net cash used in operations was $19.4 million for the third quarter of 2021 compared to $10.8 million for the third quarter of 2020. TCR2 projects net cash use of $100-105 million for 2021, the lower end of the range previously provided. We expect cash on hand to support operations through 2023.
     
  • R&D Expenses: Research and development expenses were $20.3 million for the third quarter of 2021 compared to $12.8 million for the third quarter of 2020. The increase in R&D expenses was primarily due to an increase in headcount, additional lab facilities, and manufacturing facilities.
     
  • G&A Expenses: General and administrative expenses were $6.0 million for the third quarter of 2021 compared to $4.4 million for the third quarter of 2020. The increase in general and administrative expenses was primarily due to an increase in personnel costs.
     
  • Net Loss: Net loss was $26.2 million for the third quarter of 2021 compared to $16.9 million for the third quarter of 2020.
