Most patients stayed outpatient as cema-cel hit 58.3% MRD negativity
Cellectis announced positive interim futility analysis data from Allogene’s pivotal ALPHA3 trial for cema-cel in large B-cell lymphoma, showing 58.3% MRD negativity compared to 16.7% for observation. The treatment demonstrated favorable tolerability with most patients managed as outpatient, and Cellectis is eligible for up to $340 million in milestones and royalties. However, full trial accrual and primary event-free survival analysis are not expected until mid-2028, extending the regulatory timeline.
