During the period after leukapheresis while the CAR T cells were in production, patients could have ongoing treatment, but received PET scans to confirm disease before continuing enrollment in the trial and receiving liso-cel. The time from apheresis to product release for the pivotal cohort is now under 21 days, he said.
The study was supported by Juno Therapeutics, which plans to market liso-cel. Dr. Abramson reported ties with Celgene, Gilead, Seattle Genetics, Novartis, and Genentech.
