CAMBRIDGE, Mass., Jan. 08, 2021 (GLOBE NEWSWIRE) -- TCR2 TherapeuticsInc. (Nasdaq: TCRR), a clinical-stage immunotherapy company with a pipeline of novel T cell therapies for patients suffering from cancer, today announced its strategic priorities and anticipated upcoming milestones.

“In the past twelve months, we validated the clinical utility of our unique platform and demonstrated that our TRuC-T cells consistently deliver solid tumor regression in patients. Importantly, we are the first cell therapy company to show clinical activity in ovarian cancer. We are pleased that the significant progress across our entire pipeline positions us as a leader in the solid tumor field,” said Garry Menzel, Ph.D., President and Chief Executive Officer of TCR2 Therapeutics. “We believe 2021 will be another pivotal year for TCR2, ending with three product candidates in clinical trials, most notably gavo-cel in Phase 2 trials for multiple solid tumor indications. We anticipate sharing our clinical progress at several medical conferences. We will also be presenting preclinical data on new autologous TRuC-T cell programs and, significantly, our allogeneic TRuC-T cell program targeting mesothelin. Despite the challenges posed by the ongoing pandemic, we remain focused on the execution of our strategic priorities and bringing meaningful therapies to cancer patients.”

2021 Strategic Priorities and Milestones

Gavo-cel: lead TRuC-T cell targeting mesothelin-positive non-small cell lung cancer, ovarian cancer, malignant pleural/peritoneal mesothelioma, and cholangiocarcinoma.

  • Additional safety, efficacy and translational data from Phase 1 dose escalation anticipated in first half of 2021, with data from additional non-mesothelioma patients
  • Identification of recommended Phase 2 dose (RP2D) expected in 2021
  • Initiation of Phase 2 expansion cohort anticipated in 2021

TC-110: TRuC-T cell targeting CD19-positive adult acute lymphoblastic leukemia and aggressive or indolent non-Hodgkin lymphoma.

  • Initial safety, efficacy and translational data from Phase 1 dose escalation anticipated in 2021

Pipeline Expansion: TCR2 plans to file an IND for a third TRuC-T cell program in 2021.

  • Allogeneic TRuC-T cells: preclinical data from an allogeneic TRuC-T cell targeting mesothelin-positive solid tumors anticipated in 2021
  • Autologous TRuC-T cells: preclinical data from a TRuC-T cell targeting CD70-positive solid tumors anticipated in 2021

Manufacturing: TCR2 continues to focus on building manufacturing capacity in a capital efficient manner.

  • US Manufacturing Capacity: Material for gavo-cel clinical trials expected from Elevate Bio in 2021
  • UK Manufacturing Facility: Additional clinical T cell production anticipated to come online by mid-2021

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, 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).
