TScan Therapeutics Presents Preclinical Data at the American Society of Gene and Cell Therapy 25th Annual Meeting
Identified lead TCR-T cell therapy candidate, TCR-200-A02, for the treatment of HPV-positive solid tumors, on track for IND submission in 2H22
TCR directed to a novel C*07:02-restricted epitope of MAGEA1, TSC-204-C07, on track for IND submission in 2H22
Multiplexing TCRs in vitro leads to cytotoxicity of target cell lines and cytokine-mediated enhancement of anti-tumor activity of specific TCR cells
ImmunoBank enables customized multiplexing of TCRs across both targets and HLA restrictions
Hosting virtual KOL event May 19, 2022 at 4:30 p.m. ET to share preclinical data highlights
WALTHAM, Mass., May 19, 2022 (GLOBE NEWSWIRE) -- TScan Therapeutics, Inc. (Nasdaq: TCRX), a clinical-stage biopharmaceutical company focused on the development of T-cell receptor (TCR) engineered T cell therapies (TCR-T) for the treatment of patients with cancer, presented two posters and an oral presentation around TScan’s proprietary platform technologies for its solid tumor program at the American Society of Gene and Cell Therapy (ASGCT) 25th Annual Meeting.
“The initial preclinical data on our solid tumor program presented at ASGCT demonstrate the capability of TScan’s proprietary platforms to identify novel TCRs. Through ReceptorScan, we identified TSC-200-A02 that targets an HLA-A*02:01 restricted epitope of HPV16-E7 and with TargetScan we identified TSC-204-C07 targeting a novel HLA-C*07:02 restricted epitope of MAGE-A1. We are excited to report initial preclinical results, which showed strong cytoxicity of TSC-200-A02 in HPV+ target cell lines and no off-target activity. When we multiplexed the two TCRs in vitro, we were excited to see synergistic cytotoxic activity.” said Gavin MacBeath, Ph.D., Chief Scientific Officer.
Dr. MacBeath continued, “We are on track to continue progressing IND-enabling studies for the TSC-200 series and submitting IND applications for TSC-200-A02 and TSC-204-C7 during the second half of this year. These initial preclinical results suggest that multiplexing TCRs has the potential to overcome both tumor antigen heterogeneity and HLA loss-of-heterozygosity (LOH).”

Poster presentation titled “Multiplexed TCR-T cell therapy: A strategy to enhance the efficacy of engineered T cell therapy,” presented by Gavin MacBeath, Ph.D.
Oral presentation titled “Discovery of a novel C*07:02-restriced epitope on MAGE-A1 and pre-clinical development of an enhanced TCR-T cell therapy candidate for the treatment of solid tumors,” presented by Gavin MacBeath, Ph.D.
Virtual KOL Event
The Company is hosting a virtual KOL event today, Thursday, May 19, 2022, at 4:30 p.m. ET, featuring Kai Wucherpfennig, M.D., Ph.D. Chair, Cancer Immunology and Virology and Director, Center for Cancer Immunology Research at the Dana-Farber Cancer Institute, Professor of Neurology, Brigham and Women’s Hospital and Harvard Medical School, and Associate Member, Broad Institute of MIT and Harvard. The event will provide an in-depth review of the oral and poster presentations related to solid tumor TCR-T therapy candidates, TSC-200-A02 for HPV16, and TSC-204-C07 for MAGE-A1, as well as TScan’s approach to potentially overcome antigen heterogeneity and HLA loss with multiplexed TCR-T. Following the prepared remarks, the call will be opened for a live question and answer session. To submit a question, please reach out to [email protected]. Registration for the live event can be found here. A replay will be available on the “Events and Presentations” section of the Company’s website at ir.tscan.com.
About TScan Therapeutics, Inc.
TScan is a clinical-stage biopharmaceutical company focused on the development of T cell receptor (TCR) engineered T cell therapies (TCR-T) for the treatment of patients with cancer. The Company’s lead leukemia TCR-T therapy candidates, TSC-100 and TSC-101, are in development for the treatment of patients with hematologic malignancies to eliminate residual leukemia and prevent relapse after hematopoietic stem cell transplantation. The Company is also developing multiplexed TCR-T therapy candidates for the treatment of various solid tumors. The Company has developed and continues to build its ImmunoBank, the Company’s bank of therapeutic TCRs that recognize diverse targets and are associated with multiple HLA types in order to provide customized multiplexed TCR-T therapies for patients with various types of solid tumors.
