Diffuse Large B-cell Lymphoma With no Other Specification
Conditions
Brief summary
The goal of this clinical trial is to learn the safety of OT-C001 and decide a good dose in treating relapsed or refractory diffuse large B-cell lymphoma patients. It will also learn about the preliminary activity of OT-C001. Participants will: Receive a short course of chemotherapy before OT-C001 treatment. During the study treatment, participants will recieve weekly dose of OT-C001 for 3 or 6 weeks. During the study period, participants will also receive another two drugs, rituximab and IL-2, to support OT-C001 treatment. Participants need to visit the clinic or may be hospitalized according to the study plan.
Interventions
OT-C001 will be administered by IV infusion weekly for at least 3 doses.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Incidence and severity of treatment-emergent adverse events and clinically significant findings on clinical laboratory tests, performance status, vital signs, ECGs, and physical examinations. | All assessments will be conducted from first study treatment administration through the End of Treatment or Early Termination Visit (scheduled within 14 days after the last dose). |
Secondary
| Measure | Time frame |
|---|---|
| Antitumor activity characterized by objective response rate per Lugano criteria. | Tumor will be assessed at the end treatment cycles (3 and 6 weeks after the first dose), and every 12 weeks afterwards for up to of 2 years until progression of disease or starting new anti-cancer treatments. |
Other
| Measure | Time frame |
|---|---|
| Duration of OT-C001 persistence after administering OT-C001. | From baseline (before lymphodepletion) to end of study treatment (within 14 days after the last dose of OT-C001). |
| Changes in serum cytokine levels | From baseline (before lymphodepletion) to end of study treatment (within 14 days after the last dose of OT-C001) |
