Non Hodgkin Lymphoma Clinical Trial
Evaluation of Safety and Efficacy of Allo GDA-201 NK Cells in Patients With Relapsed/Refractory B Cell NHL
This is an open-label, non-randomized, interventional, single group assignment study of GDA-201, an allogeneic cryopreserved NK cell therapy derived from donor peripheral blood, in combination with rituximab, monoclonal anti-CD20 antibody, for patients with relapsed or refractory B Cell non-Hodgkin lymphoma (NHL).
The study is divided into a phase I dose escalation phase and a phase II expansion phase.
Patients with relapsed or refractory follicular lymphoma (FL) or diffuse large B-cell lymphoma (DLBCL)/high grade B-cell lymphoma (HGBCL) will receive GDA-201 followed by a short course of low-dose interleukin-2 (IL-2). Rituximab will be administered prior to and after GDA-201 infusion.
Phase I: Dose escalation phase The objective of Phase I is to evaluate the safety of GDA-201 in patients with FL, DLBCL/ HGBCL, marginal zone lymphoma or mantle cell lymphoma. The maximal tolerated dose (MTD) and recommended Phase II Dose (RP2D) will be determined based on dose limiting toxicities (DLT).
Phase II expansion phase The objective of the Phase II expansion cohort is to evaluate the safety and efficacy of GDA-201 in two patient cohorts, FL and DLBCL/HGBCL.
Patients must have relapsed/refractory FL or HGBCL/DLBCL that has failed conventional therapy defined as follows:
Received at least 2 prior lines of therapy
Transplant ineligible patients allowed assuming they meet criterion a.
Patients who received prior chimeric antigen receptor modified T-cells (CAR-T) cell therapy or are considered ineligible for CAR-T therapy per the investigator's discretion
FL transformed to HGBCL: Must have received at least 1 line of therapy after transformation to DLBCL/HGBCL
Patients must be at least 18 years of age
Patients must have adequate hematologic, hepatic, renal, cardiac and pulmonary function prior to any study treatment.
Time between previous treatment and first dose of study treatment (rituximab):
Allogeneic HSCT < 6 months prior to study treatment
Autologous HSCT < 3 months prior to study treatment
CAR-T < 2 months prior to study treatment
