TScan Therapeutics Announces Upcoming Oral Presentation of Data from the ALLOHA™ Phase 1 Heme Trial at the 66th American Society of Hematology Annual Meeting and Exposition
All TSC-treated patients were relapse-free and MRD negative as of data cutoff
TSC-100 and TSC-101 demonstrate the potential to reduce relapse rates and increase relapse-free survival in patients with AML, ALL, or MDS undergoing allogeneic HCT with reduced intensity conditioning
Company to host virtual KOL event featuring Ran Reshef, M.D., M.Sc., on Tuesday, December 10, at 8:00 a.m. ET
WALTHAM, Mass., Nov. 05, 2024 (GLOBE NEWSWIRE) -- TScan Therapeutics, Inc. (Nasdaq: TCRX), a clinical-stage biotechnology company focused on the development of T cell receptor (TCR)-engineered T cell (TCR-T) therapies for the treatment of patients with cancer, today announced that preliminary results from the ALLOHA™ Phase 1 trial of TSC-100 and TSC-101, in patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and myelodysplastic syndrome (MDS) undergoing allogeneic hematopoietic cell transplantation (HCT) with reduced intensity conditioning, will be featured in an oral presentation at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition being held December 7 – 10 in San Diego, CA. A copy of the abstract is now available online via the ASH website at www.hematology.org.
“Disease relapse is the leading cause of death in patients undergoing transplant with reduced intensity conditioning,” said Gavin MacBeath, Ph.D., Chief Executive Officer. “TSC-100 and TSC-101 were designed with this significant unmet need in mind, and preliminary clinical and translational data from the ALLOHA trial supports the safety and potential of TSC-100 and TSC-101 to reduce relapses and increase relapse-free survival. We look forward to providing additional data from the ongoing trial at the meeting in December.”
In the ongoing ALLOHA Phase 1 trial (NCT05473910), patients receive either TSC-100 or TSC-101 post-HCT, whereas control-arm patients receive HCT alone as per standard of care. As of the July 8, 2024 data cut, 27 patients were enrolled in the trial and had undergone HCT, with 16 in the treatment arm and 11 in the control arm. No relapses occurred in the treatment arm versus three relapses in the control arm. Median time to relapse was not evaluable in TSC-treated patients, where no relapses occurred, versus 159 days in the control arm. All five TSC-treated patients that reached one-year follow-up remained relapse-free and MRD negative as of the data cutoff, consistent with effective elimination of residual cancer cells post-HCT. No dose limiting toxicities occurred following TSC-100 or TSC-101 infusions and safety was similar in the treatment and control arms, with expected post-HCT adverse events.
Enrollment in the ALLOHA Phase 1 trial continues and updated data will be presented at the meeting in December.
A copy of the presentation materials will be added to the “Publications” section of the Company’s website at tscan.com once the presentation has concluded.
