Why is TScan Therapeutics stock collapsing today?
TScan Therapeutics (TCRX) shares fell 28.8% after announcing a strategic reorganization, including a 75% workforce reduction, pausing its Phase 3 ALLOHA-2 trial due to insufficient capital, and redirecting resources to solid tumor candidates. The company expects $55M in cost savings by 2027 and has a cash runway into Q4 2027. It is seeking collaboration partners for paused programs.
