Trial of Magrolimab (Hu5F9-G4) in Combination With Rituximab or Rituximab + Chemotherapy in Participants With Relapsed/Refractory B-cell Non-Hodgkin's Lymphoma
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 autologous stem cell transplant (ASCT) ineligible DLBCL participants.

---|---|---|
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. |
|
Experimental Magrolimab + Rituximab, Phase 2 Indolent Lymphoma |
Participants with indolent lymphoma will receive magrolimab based on RP2DS from Phase 1b portion of the study in combination with rituxumab 375 mg/m^2. |
|
Experimental Magrolimab + Rituximab, Phase 2 Diffuse Large B-Cell lymphoma |
Participants with diffuse large B-cell lymphoma (DLBCL) will receive magrolimab based on RP2DS from Phase 1b portion of the study in combination with rituxumab 375 mg/m^2. |
|
Experimental Magrolimab + R-GemOx, Phase 1b Safety Dose Escalation Phase |
Autologous stem cell transplant (or transplantation) ineligible DLBCL participants will receive 1 mg/kg magrolimab priming dose on Day 1 for Cyle 1 followed by maintenance doses of 30 or 45 mg/kg on Days 8, 11, 15, 22, and 29 for Cycle 1, every week for Cycle 2, and every 2 weeks for each cycle to determine maximum tolerated dose (MTD) + rituxumab 375 mg/m^2 + gemcitabine 1000 mg/m^2 + oxaliplatin 100 mg/m^2. Cycle length is 28 days. |
|
Experimental Magrolimab + R-GemOx, Phase 1b Dose Expansion Phase |
Autologous stem cell transplant (or transplantation) ineligible DLBCL participants will receive magrolimab at a dose determined from Phase 1b Safety Dose-Escalation Phase in combination with rituxumab 375 mg/m^2 + gemcitabine 1000 mg/m^2 + oxaliplatin 100 mg/m^2. |
