Purpose

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 aspartate aminotransferase (ASCT) ineligible DLBCL participants.

ArmDescriptionAssigned Intervention
Experimental
Magrolimab + Rituximab, Phase 1b Dose Escalation
Participants with B-cell non-Hodgkin's lymphoma will receive 1 mg/kg magrolimab priming dose on Day 1 of Cycle 1 followed by weekly maintenance doses of 10, 20, 30, or 45 mg/kg on Days 8, 15, 22 for Cycle 1 and Days 1, 8, 15, and 22 for each cycle to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose and schedule (RP2DS) in combination with rituxumab 375 mg/m^2. Cycle length is 28 days.
