TScan Therapeutics cuts workforce by 75% and pauses Phase 3 programme in strategic pivot

TScan Therapeutics is cutting approximately 75% of its workforce and pausing further enrolment in its Phase 3 ALLOHA-2 study as it redirects resources towards in vivo cell therapy programmes for solid tumours.
The restructuring reflects a major strategic shift driven by capital constraints, with TScan prioritising development of its solid-tumour TCR-T programmes.
The company is substantially reducing operating costs while concentrating its remaining resources on programmes it believes offer the strongest future development potential.
