This study is being done to determine the safety, efficacy and tolerability of a single 50 mCi dose of 131I-Apamistamab given prior to FDA approved (commercially available) infusion in patients with Relapsed or refractory (R/R) non-Hodgkin lymphoma.
This is an open-label single-cohort multi-institutional study of 131I-Apamistamab followed by CAR-T cell therapy for patients with (R/R) DLBCL. Patients will receive a 50 mCi single planned 131I-Apamistamab dose prior to CAR-T cell infusion for lymphodepleting conditioning. There will be a 6-patient safety run-in to assess safety.
Inclusion Criteria: 1. Patients with diffuse large B-cell lymphoma (de novo or DLBCL transformed from an indolent lymphoma (follicular lymphoma, chronic lymphocytic leukemia \[Richter syndrome\]) or high-grade B-cell lymphoma (HGBL): ("DLBCL patients") * Defined as relapsed or refractory DLBCL or high-grade B-cell lymphoma (HGBL) following at least one or more prior chemoimmunotherapy regimen (with at least one course including an anthracycline and CD20-directed therapy) following diagnosis of de novo DLBCL/HGBL or DLBCL arising from indolent lymphoma and requiring further treatment and d…
