• FDA Agreement for Lead Heme Program

  TScan Therapeutics reached an agreement with the U.S. Food and Drug Administration (FDA) on a registrational path forward for its lead product candidate, TSC-101, for acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) in Q4 2025. The pivotal study will mirror the ongoing Phase 1 ALLOHA trial.

• Strategic Prioritization and Workforce Reduction

  The company made a strategic decision on November 3, 2025, to prioritize clinical development of its heme program and pause further enrollment in its solid tumor Phase 1 trial (PLEXI-T). This included a workforce reduction of approximately 30% (66 roles), expected to generate annual cost savings of $45.0 million in 2026 and 2027.

• Extended Cash Runway

  As of December 31, 2025, TScan Therapeutics had $152.4 million in cash and cash equivalents, which is expected to fund its operating plan into the second half of 2027. This follows significant capital raises in 2023 and 2024, including public offerings and a direct offering of pre-funded warrants.

• Increased Collaboration Revenue

  Collaboration and license revenue increased significantly to $10.3 million for the year ended December 31, 2025, up from $2.8 million in 2024, primarily due to research activities under the Amgen Agreement.

TScan Therapeutics has outlined a significant strategic shift and provided a positive outlook for its lead clinical program in its annual report. The company has secured an agreement with the FDA on a registrational path for TSC-101, its lead T-cell therapy candidate for hematologic malignancies, which is a major de-risking event for a clinical-stage biotech. This strategic focus is accompanied by a 30% workforce reduction and a pause in its solid tumor Phase 1 trial, aimed at conserving capital and extending its cash runway into the second half of 2027. While the company reported increased net losses, the successful advancement of its lead program and improved liquidity position are critical positive developments for its long-term prospects.
