B-Cell Non-Hodgkin Lymphoma-Recurrent, B-Cell Non-Hodgkin Lymphoma-Refractory
Conditions
Brief summary
A phase I, open-label clinical study to evaluate the safety, tolerability, and efficacy of LUCAR-G39D, a dual-targeted cell preparation targeting CD19/CD20, in patients with relapsed/refractory B-cell non-Hodgkin lymphoma.
Detailed description
This is an open-label, dose-escalation/dose extension study to assess the safety, tolerability, and efficacy of LUCAR-G39D in the patient ≥ 18 years of age with relapsed or refractory B-cell non-Hodgkin lymphoma. Subjects who meet the eligibility criteria will receive a single dose of LUCAR-G39D injection. The study will include the following sequential phases: screening, pre-treatment (lymphodepleting chemotherapy), treatment, and follow-up.
Interventions
Prior to infusion of the LUCAR-G39D, subjects will receive a conditioning premedication regimen consisting of cyclophosphamide and fludarabine.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence, severity and type of TEAEs (Treatment-emergent Adverse Events) | Through study completion , an average of 2 years after LUCAR-G39D infusion (Day 1) | An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. |
| Pharmacokinetics in peripheral blood | Through study completion , an average of 2 years after LUCAR-G39D infusion (Day 1). | CAR positive T cells and CAR transgene levels in peripheral blood after LUCAR-G39D infusion. |
| Pharmacokinetics in bone marrow | Through study completion , an average of 2 years after LUCAR-G39D infusion (Day 1) | CAR positive T cells and CAR transgene levels in bone marrow after LUCAR-G39D infusion. |
| The recommended Phase II dose (RP2D) for this cell therapy | Within 30 days after LUCAR-G39D infusion | RP2D established through ATD+BOIN design and the DLTs occurring following CAR T-cell infusion. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duration of Response (DoR) | Through study completion, an average of 2 years after LUCAR-G39D infusion (Day 1) | Duration of Remission (DoR) is defined as the time from the first documentation of remission (CR or PR) to the first documented relapse evidence of the responders. |
| Overall Response Rate (ORR) | Through study completion, an average of 2 years after LUCAR-G39D infusion (Day 1) | Objective Response Rate (ORR) is defined as the proportion of subjects who achieve CR or PR after treatment via LUCAR-G39D cell infusion |
| Immunogenicity assessment of LUCAR-G39D cells | Through study completion, an average of 2 years after LUCAR-G39D infusion (Day 1) | The incidence of Anti- LUCAR-G39D antibody in patients who received LUCAR-G39D cells infusion |
| Progression-free survival (PFS) | Through study completion, an average of 2 years after LUCAR-G39D infusion (Day 1) | Progression Free Survival (PFS) is defined as the time from the date of first infusion of the LUCAR-G39D to the first documented disease progression (according to Lugano 2014) or death (due to any cause), whichever occurs first |
| Overall Survival (OS) | Through study completion, an average of 2 years after LUCAR-G39D infusion (Day 1) | Overall Survival (OS) is defined as the time from the date of first infusion of LUCAR-G39D to death of the subject |
| Time to Response (TTR) | Through study completion, an average of 2 years after LUCAR-G39D infusion (Day 1) | Time to Response (TTR) is defined as the time from the date of first infusion of LUCAR-G39D to the date of the first response evaluation of the subject who has met all criteria for CR or PR. |
