CAMBRIDGE, Mass., May 12, 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 first quarter ended March 31, 2022 and provided a corporate update.
“We are very pleased with the momentum generated in the last quarter as we initiated the next phases on two clinical programs and expect to present in July an expanded dataset on 30 patients treated with gavo-cel,” said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR² Therapeutics. “The consistent tumor regression observed with gavo-cel in Phase 1 establishes a baseline efficacy and safety profile upon which we can build in Phase 2. With the initiation of the TC-510 Phase 1 clinical trial, which includes the treatment of pancreatic cancer, colorectal cancer and triple negative breast cancer, we have an opportunity to expand the number of indications potentially addressable with our TRuC-T cell therapies. We look forward to a busy second half of execution as we scale these clinical trials as well as build out our preclinical pipeline targeting CD70 with enhancements and allogeneic strategies.”
TCR² initiated the Phase 2 expansion portion of the ongoing Phase 1/2 clinical trial of gavo-cel, its first-in-class TRuC-T cell targeting mesothelin-expressing solid tumors. Enrollment is ongoing and the Company expects to report on progress from the Phase 2 portion of the clinical trial in the second half of 2022.
TCR² announced the Company plans to present the expanded Phase 1 dataset for gavo-cel from the dose escalation portion of the Phase 1/2 clinical trial of gavo-cel in patients with treatment refractory mesothelin-expressing solid tumors in July 2022. The presentation will focus on safety, efficacy and translational data and include 30 patients from the Phase 1 dose escalation, with data from additional malignant pleural/peritoneal mesothelioma (MPM) and ovarian patients.
TCR² announced the U.S. Food and Drug Administration (FDA) cleared the investigational new drug (IND) application for TC-510, a TRuC-T cell targeting mesothelin that co-expresses a PD-1:CD28 chimeric switch receptor. The Phase 1/2 clinical trial is evaluating the safety and efficacy of TC-510 in patients with mesothelin-expressing MPM, ovarian cancer, pancreatic cancer, colorectal cancer and triple negative breast cancer. The Company expects to report on progress from the Phase 1 portion of the clinical trial in the second half of 2022.
Present the expanded Phase 1 dataset for gavo-cel in July 2022.
Provide an update from the Phase 2 portion of the ongoing gavo-cel Phase 1/2 clinical trial in the second half of 2022.
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.
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.
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.
Cash Position: TCR² ended the first quarter of 2022 with $232.2 million in cash, cash equivalents, and investments compared to $265.6 million as of December 31, 2021. Net cash used in operations was $31.1 million for the first quarter of 2022 compared to $23.9 million for the first quarter of 2021. TCR² projects net cash use of $115-125 million for 2022, the lower end of the range previously provided. We expect cash on hand to support operations into 2024.
R&D Expenses: Research and development expenses were $22.9 million for the first quarter of 2022 compared to $15.9 million for the first quarter of 2021. The increase in R&D expenses was primarily due to an increase in headcount, clinical trial expenses associated with patient treatment and manufacturing, and manufacturing facilities expenses.
G&A Expenses: General and administrative expenses were $6.3 million for the first quarter of 2022 compared to $5.7 million for the first quarter of 2021. The increase in general and administrative expenses was due to an increase in personnel costs and other professional fees.
Net Loss: Net loss was $29.1 million for the first quarter of 2022 compared to $21.5 million for the first quarter of 2021.
TCR² Therapeutics management is scheduled to participate at the following upcoming conferences.
H.C. Wainwright Global Investment Conference: Garry Menzel, President and Chief Executive Officer of TCR² Therapeutics, will present an update on Company progress on Tuesday, May 24, 2022 at 7:00am ET
About TCR² Therapeutics
TCR² Therapeutics Inc. is a clinical-stage cell therapy company developing a pipeline of novel T cell therapies for cancer patients suffering from solid tumors. The company is focused on the discovery and development of product candidates against novel and complex targets utilizing its proprietary T cell receptor (TCR) Fusion Construct T cells (TRuC®-T cells). The TRuC platform is designed to specifically recognize and kill cancer cells by harnessing signaling from the entire TCR, independent of human leukocyte antigens (HLA).

The ongoing gavo-cel Phase 1/2 clinical trial is evaluating the safety and efficacy of gavo-cel in patients with mesothelin-expressing MPM, ovarian cancer, non-small cell lung cancer (NSCLC) and cholangiocarcinoma.
In the Phase 2 portion of the clinical trial, patients will receive gavo-cel at the recommended Phase 2 dose (RP2D)(1x108 cells/m2). A total of 75 patients will be treated in the MPM cohort and a total of 20 patients will be treated in each one of the following indications: ovarian, NSCLC and cholangiocarcinoma. In the MPM cohort, patients will be randomized to receive either single agent gavo-cel, gavo-cel in combination with Opdivo (nivolumab), or gavo-cel in combination with Opdivo and Yervoy (ipilimumab). In ovarian, NSCLC and cholangiocarcinoma, all patients will receive gavo-cel in combination with Opdivo.
TC-510 is a mesothelin-targeted TRuC-T cell that co-expresses a PD-1:CD28 chimeric switch receptor to provide a local costimulatory signal by engaging with PD-L1 expressed in the hostile tumor microenvironment and converting the negative inhibitory signal into a positive costimulatory signal.
The TC-510 Phase 1/2 clinical trial is evaluating the safety and efficacy of TC-510 in patients with mesothelin-expressing MPM, ovarian cancer, pancreatic cancer, colorectal cancer and triple negative breast cancer.
The Phase 1 portion of the clinical trial utilizes a modified 3+3 design with five escalating dose levels for TC-510 (50x106, 100x106, 130x106, 160x106, and 200x106 cells). At each dose level, TC-510 will be treated with lymphodepletion chemotherapy and after the first patient is treated at each dose level, a 28-day safety observation period is instituted. Then, patients 2 and 3 may be infused simultaneously. The primary objective for the study is patient safety with a key secondary objective to determine the RP2D. In addition to standard measures of safety and efficacy, translational work includes the assessment of expansion, trafficking, and persistence of TC-510 T cells.
