A Phase 1 Open-label, Single Arm, Multicenter Study Evaluating the Safety and Efficacy of KITE-197 in Subjects With Relapsed or Refractory Large B-cell Lymphoma

Phase 1 Interventional Gilead Sciences · NCT06079164

This study is testing a new treatment called KITE-197 for people with relapsed or refractory large B-cell lymphoma to see if it is safe and effective in helping them achieve remission.

What this trial studies

This clinical trial consists of two phases aimed at evaluating the safety and effectiveness of KITE-197 in participants with relapsed or refractory large B-cell lymphoma (r/rLBCL). Phase 1a focuses on determining the safety, tolerability, and appropriate dosing of KITE-197, while Phase 1b assesses the efficacy of the recommended dose by measuring the complete remission rate. Participants will be monitored for approximately 24 months post-infusion, followed by long-term follow-up for up to 15 years. The study involves the administration of KITE-197 along with Cyclophosphamide and Fludarabine.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with relapsed or refractory large B-cell lymphoma who have at least one measurable lesion and adequate organ and bone marrow function.

Not a fit: Patients with a history of certain malignancies, prior stem cell transplants, or specific previous therapies targeting CD19 may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat relapsed or refractory large B-cell lymphoma.

How similar studies have performed: Other studies targeting similar conditions with innovative therapies have shown promising results, indicating potential for success in this approach.

Individuals who meet these criteria may be eligible

* History of autoimmune disease (eg, Crohn's disease, rheumatoid arthritis, systemic lupus) resulting in end organ injury or requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years
* History of symptomatic deep vein thrombosis (DVT) or pulmonary embolism within 3 months before enrollment. Catheter induced DVT which has been treated for at least 6 weeks prior to enrollment is permitted
* Females of childbearing potential who are pregnant or breastfeeding because of the potentially dangerous effects of the preparative chemotherapy on the fetus or infant
