Study of Safety and Efficacy of KTE-C19 in Combination With Atezolizumab in Adults With Refractory Diffuse Large B-Cell Lymphoma (DLBCL)

Trial ID or NCT#

NCT02926833

Status

not recruiting iconNOT RECRUITING

Purpose

The primary objective of phase 1 is to evaluate the safety of KTE-C19 and atezolizumab combination regimens. The primary objective of phase 2 is to evaluate the efficacy of KTE-C19 and atezolizumab, as measured by complete response rate in participants with refractory diffuse large B-cell lymphoma (DLBCL). Participants who received an infusion of KTE-C19 will complete the remainder of the 15 year follow-up assessments in a separate long-term follow-up study, KT-US-982-5968 (NCT05041309).
