A Phase 2, Open-Label, Multicenter, Basket Study Evaluating the Safety and Efficacy of Brexucabtagene Autoleucel in Adults with Rare B-cell Malignancies (ZUMA-25) – Substudy D - Relapsed/Refractory Hairy Cell Leukemia (HCL)
Overview
- Phase
- Phase 2
- Status
- Completed
- Sponsor
- Kite Pharma Inc.
- Enrollment
- 15
- Locations
- 18
- Primary Endpoint
- The primary endpoint of ZUMA-25 as per the master protocol is response rates by central assessment as defined in each substudy. The primary end point of Substudy D (HCL) is ORR by central assessment defined as the proportion of subjects who achieve either complete response (CR) or partial response (PR)
Overview
Brief Summary
The primary objective of ZUMA-25 is to evaluate the efficacy of brexucabtagene autoleucel in subjects with rare B-cell malignancies, by determining the Response Rates as defined within the substudies by central assessment. The primary objective of ZUMA-25 substudy D (HCL) is to evaluate the efficacy of brexucabtagene autoleucel in subjects with HCL by determining the objective response rate (ORR) by central assessment.

Secondary Outcomes
- The secondary endpoints of ZUMA-25 as per the master protocol are: • CR rate by central assessment as defined in each substudy
- • Duration of Response
- • Overall Survival
- • Progression-free survival
- • Time to next treatment defined as the time from enrollment (for Full Analysis Set [FAS]) or brexucabtagene autoleucel infusion (for modified intention to treat [mITT]) to the initiation of subsequent anticancer therapy/treatment
- • Time to first response from brexucabtagene autoleucel infusion to the first response as defined in the substudy
- The Substudy D (HCL) specific secondary endpoint is ORR by investigator assessment defined as the proportion of subjects who achieve either CR or PR
