This study is a Phase 1, multicenter, open-label study designed to evaluate the safety and efficacy of MT-601 in patients with relapsed or refractory Non-Hodgkin lymphoma (NHL) who either received CD19+ chimeric antigen receptor (CAR) T cell therapy or are ineligible for CD19+ CAR T cell therapy. The study will consist of two portions: 1) Dose Escalation (3+3 design) followed by 2) Dose Expansion. The purpose of the Dose Escalation portion of the study is to test safety and tolerability of higher doses of MT-601 up to 400 x 106 cells. The Dose Expansion portion of this study will begin after completion of the Dose Escalation portion. The purpose of the Dose Expansion portion of the study is to evaluate the clinical efficacy of MT-601 at the dose determined to be safe in the Dose Escalation portion.
This study is a Phase 1multicenter study with a Dose Escalation and Dose Expansion evaluating safety and efficacy of MT-601 administration to patients with Relapsed or Refractory NHL. The dose administered is 200 x 10^6 cells (flat dosing).
