A Phase 1 interventional study of Cyclophosphamide and Fludarabine in Relapsed/Refractory Large B-cell Lymphoma, sponsored by Kite, A Gilead Company. Terminated at 10 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-03-04.
Sponsored by Kite, A Gilead Company · Phase 1, Interventional, and Treatment
The primary objectives of this study are:
Phase 1: To evaluate the safety of sequenced therapy with lenzilumab and axicabtagene ciloleucel in participants with relapsed or refractory large B-cell lymphoma and identify the most appropriate dose of lenzilumab for Phase 2.
Phase 2: To evaluate the incidence of neurologic events with sequenced therapy given at the recommended Phase 2 dose (RP2D) of lenzilumab in participants with relapsed or refractory large B-cell lymphoma.
This study was intended to be a Phase 1/2, but the planned Phase 2 part has been canceled.
All participants who received an infusion of lenzilumab and axicabtagene ciloleucel will be provided the opportunity to transition to a separate long-term follow-up (LTFU) study, KT-US-982-5968.
