WALTHAM, Mass. - TScan Therapeutics, Inc. (NASDAQ:TCRX), a clinical-stage biopharmaceutical company, announced positive data from its Phase 1 clinical trial of TSC-100 and TSC-101 therapies designed to treat residual disease and prevent relapse in patients with certain blood cancers. The data, presented at the 2024 Tandem Meetings, indicated that all eight patients treated with these therapies achieved and maintained complete donor chimerism, a potential early indicator of treatment success.
The trial includes patients with acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), or acute lymphocytic leukemia (ALL) who have undergone hematopoietic cell transplantation (HCT). The company's Chief Medical Officer, Debora Barton, M.D., highlighted the significance of one high-risk, TP53-mutated MDS patient remaining relapse-free for over a year following treatment with TSC-101. Additionally, a patient with AML converted from detectable minimal residual disease (MRD) to undetectable following treatment with TSC-101.
In contrast, two out of six patients in the control arm relapsed after receiving standard HCT alone, with one patient succumbing to the disease. This comparison underscores the potential of TSC-100 and TSC-101 to improve outcomes for patients at risk of relapse post-transplant.
The study's primary endpoints focus on safety and dose-finding, while secondary and exploratory endpoints include relapse rates and supportive surrogates of efficacy, such as donor chimerism and MRD.
TScan's CEO, Gavin MacBeath, Ph.D., commented on the encouraging results, emphasizing the importance of sustained complete donor chimerism in patients treated with the company's cell therapy products. With approximately 60% of patients cured by HCT, the remaining 40% who relapse face limited treatment options and poor prognosis. TScan's therapies aim to improve these odds.
The company will host a virtual KOL event today to discuss the data further. The event will feature experts from the City of Hope and Columbia University Irving Medical Center.
