(GlobeNewswire)
- P1 | N=63 | ALLOHA (NCT05473910) | Sponsor: TScan Therapeutics, Inc. | "To date, 38 patients have been enrolled in the trial and undergone HCT....To date, event-free survival strongly favors the treatment arm (HR=0.30; p=0.04) and early trends suggest a lower probability of relapse (HR=0.28; p=0.14). 2 of 26 (8%) treatment-arm patients relapsed compared to 4 of 12 (33%) control-arm patients. One treatment-arm relapse and subsequent mortality occurred in a very high-risk patient who was taken to transplant without first achieving complete remission, and the other was an extramedullary relapse in the patient’s central nervous system with no evidence of systemic relapse....8 of 38 (21%) patients in the study had TP53 mutations, with 6 cases in the treatment arm and 2 cases in the control arm....TSC-100 and TSC-101 infusions were well-tolerated at all three dose levels with no dose-limiting toxicities."

(GlobeNewswire)
- "Research and development expenses for the second quarter of 2024 were $26.9 million, compared to $21.2 million for the second quarter of 2023. The increase of $5.7 million was primarily driven by an increase in clinical studies expense associated with the ongoing enrollment of our ALLOHA Phase 1 heme trial and start-up activities and initial enrollment in our Phase 1 solid tumor clinical trial, as well as an increase in personnel expenses due to additional headcount in support of our expanded research and development activities."

Patients are treated with these engineered immune cells immediately following transplant, when the number of surviving cancer cells should be at its lowest and easiest to eliminate, thus representing the best chance for achieving relapse-free survival."

Micro-Chimerism Detected By Highly Sensitive AlloHemeTM Solution Is Associated with Treatment Response and Relapse after Allogeneic Stem Cell Transplantation
(TCT-ASTCT-CIBMTR 2024)
- P=N/A, P1 | "Trial 2: NCT05473910 (TSCAN-001, TScan Inc.) is a multi-arm non-randomized controlled Phase 1 study evaluating the safety and efficacy of TScan's TSC100 and TSC101 - allogeneic T-cell receptor-engineered T cells that target haematopoietically restricted antigens HA-1 and HA-2 respectively, both presented on HLA-A*02:01, in mismatched reduced-intensity conditioning (RIC)-haplo donor HCT recipients. Additionally, where MRD results were available, AH CD33 iMC was associated with MRD (p=0.019, N=79) (Table 3). These interim results suggest a potential utility of MC measured by AlloHeme, an ultra-sensitive NGS-based chimerism monitoring solution, as a non-invasive predictive biomarker for treatment response and relapse in post allo-HCT patients."

TSC-100 and TSC-101, TCR-T Cell Therapies That Target Residual Recipient Cells after Reduced Intensity Conditioning Transplantation, Induce Complete Donor Chimerism with Favorable Prognosis: Early Results of a Phase 1 Trial
(TCT-ASTCT-CIBMTR 2024)
- P=N/A, P1 | "The prognostic value of complete donor chimerism by AlloHeme was evaluated in the ACROBAT study (NCT04635384) in which 73 patients achieved >99.9% chimerism in CD33+ cells and, after median follow-up of 9 months/ 270 days (range 72-608 days), 3 relapsed (4%), comparing favorably with 18-20% 6-month relapse rates in CIBMTR data. In summary, TSC-100 and TSC-101 post-HCT induce MRD negativity and complete donor chimerism which may be associated with substantially reduced relapse rates."
