Trial of Magrolimab (Hu5F9-G4) in Combination With Rituximab or Rituximab + Chemotherapy in Participants With Relapsed/Refractory B-cell Non-Hodgkin's Lymphoma

Summary

The primary objectives of this study are: * To investigate the safety and tolerability, and to define the recommended Phase 2 dose and schedule (RP2DS) for magrolimab in combination with rituximab and for magrolimab in combination with rituximab, gemcitabine, and oxaliplatin (R-GemOx). * To evaluate the efficacy of magrolimab in combination with rituximab in participants with indolent lymphoma and diffuse large B-cell lymphoma (DLBCL) and to evaluate the efficacy of magrolimab in combination with R-GemOx in autologous stem cell transplant (ASCT) ineligible DLBCL participants.
