Cellectis (CLLS) said Tuesday the US Food and Drug Administration has given the Regenerative Medicine Advanced Therapy, or RMAT, designation to lasme-cel to treat relapsed or refractory B-cell acute lymphoblastic leukemia.
The designation is backed by phase 1 results showing "promising efficacy and a manageable safety profile," the company said.
Final phase 1 data from the trial will be presented in a session at the 2026 Congress of the European Hematology Association on June 13, Cellectis said.
