简要总结
The purpose of this study is to evaluate the safety and tolerability of MT-3724 in combination with gemcitabine and oxaliplatin (GEMOX) in participants with relapsed or refractory B-Cell NHL.
详细描述
This is a multi-center, open-label two-part study evaluating the safety and tolerability of MT-3724 in combination with GEMOX in relapsed or refractory B-cell Lymphoma patients.
Part 1: (MT-3724 Dose Escalation) Define the maximum tolerated dose (MTD) of MT-3724 in combination with standard treatment of GEMOX
Part 2: (MTD Expansion Cohort) Confirm the safety and tolerability of the MTD of MT-3724 from Part 1 in the MTD Expansion Cohort, where MT-3724 will be given at the MTD in combination with GEMOX. In addition, the PK, PD, immunogenicity and tumor response at the MTD of MT-3724 in combination with GEMOX will be more thoroughly evaluated in Part 2.
In original protocol and amendment 2, participants will be administered intravenous (IV) MT-3724 over 1 hour on Days 1, 3, 5, 8, 10 and 12 in Cycles 1 and 2 (each 28-day cycle) and on Days 1, 8, 15, and 22 in Cycles 3 and 4 (each 28-day cycle). Participants will also be administered Gemcitabine 1000 milligrams per meter square (mg/m^2) as 30-minute IV infusion and Oxaliplatin 100 mg/m^2 as 2-hour IV infusion on Days 2 and 16 in Cycles 1, 2, 3 and 4 (each 28-day cycle). Per amendment 2, participants will be administered MT-3724 on Days 1, 3, 5, 8, 10, 12, 15, 22, 29, and 36 in Cycle 1 (42-day cycle). In Cycles 2, 3 and 4, MT-3724 will be administered weekly on Days 1, 8, 15, and 22 of each 28-day cycle. Gemcitabine and oxaliplatin will be administered on Days 16 and 30 of Cycle 1 and on Days 2 and 16 in Cycles 2, 3 and 4 (42-day cycle for Cycle 1 and 28-day cycle for Cycle 2, Cycle 3 and Cycle 4).
Continued Treatment with MT-3724 in combination with GEMOX will continue for four cycles of until death, disease progression, unacceptable toxicity, withdrawal of consent or another reason for withdrawal.

主要结局
Part 1 and 2: Number of Participants With Dose Limiting Toxicities (DLTs)
时间窗: Up to 168 Days
A DLT is any treatment-emergent adverse event (TEAE) that occurred after the start of infusion in cycle 1 of Part 1 and the TEAE is at least possibly related to the study drug, as determined by the sponsor after consultation with the investigator(s).
Part 1 and 2: Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
时间窗: Up to 168 Days
An AE is as any untoward medical occurrence in a participant or clinical investigation in a participant administered a pharmaceutical product(s) and which does not necessarily have to have a causal relationship with this experimental intervention(s). A SAE is any AE that is fatal or life-threatening, permanently disabling (incapacitating or interfering with the ability to resume usual life patterns), results in unplanned in-subject hospitalization or prolongation of an existing hospitalization, results in a congenital abnormality or birth defect, or any other situation that require medical or scientific judgement. Number of participants with common \>=0 percent (%) TEAEs and SAEs are presented.
