Details and patient eligibility


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).

Full description

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.
