Study of KITE-197 in Participants With Relapsed or Refractory Large B-cell Lymphoma

• Status: Recruiting
• Trial end date: 2027-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This study will have two Phases: Phase 1a and Phase 1b. The goal of Phase 1a of this clinical study is to learn more about the safety, tolerability and dosing of study drug KITE-197, in participants with relapsed or refractory large B-cell lymphoma (r/rLBCL). The goal of Phase 1b of this clinical study is learn about the effectiveness of the recommended dose of KITE-197 in participants with r/r LBCL.

The primary objectives of this study are:

Phase 1a: To evaluate the safety of KITE-197 in participants with r/r LBCL and determine the target dose level for Phase 1b.

Phase 1b: To evaluate the efficacy of KITE-197 in participants with r/r LBCL as measured by the complete remission (CR) rate.
