研究概览
简要总结
The primary objectives of this study are:
Phase 1: To evaluate the safety of axicabtagene ciloleucel in combination with utomilumab and to identify the most appropriate dose and timing of utomilumab to carry forward into Phase 2
Phase 2: To evaluate the efficacy of axicabtagene ciloleucel and utomilumab as measured by complete response rate in participants with refractory large B-cell lymphoma
详细描述
This study was intended to be a Phase 1/2. Enrollment was stopped prior to completion of Phase 1 portion of the study based on the sponsor's decision to end the program. No participants were enrolled in Phase 1 Cohort 5 and Phase 2.
After the study ends, participants who received an infusion of axicabtagene ciloleucel and utomilumab will complete the remainder of the 15-year follow-up assessments in a separate Long-term Follow-up study, KT-US-982-5968 (NCT05041309).
