简要总结
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.

Thereafter from Cycle 8 and beyond, rituximab will be administered on Day 1 of every other cycle (on even cycles). Each Cycle length of 28 days.
干预措施: Rituximab (Drug)
结局指标
主要结局
Phase 1b: Percentage of Participants Experiencing Dose-limiting Toxicities (DLTs) in Antibody Treatment Combination
时间窗: Up to 28 days
DLTs refer to toxicities experienced during the first 28 days of study treatment that have been judged to be clinically significant and related to study treatment in participant in Phase 1b. A DLT was defined as any Grade 3 or greater AE that was assessed as related to either magrolimab and/or rituximab that occurred during the 4-week DLT observation period. Any treatment-emergent adverse event (TEAE) that was, in the opinion of the Clinical Trial Steering Committee, of potential clinical significance such that further dosing exposed participants to unacceptable risk, was considered a DLT.
Phase 1b: Percentage of Participants Experiencing Dose-limiting Toxicities (DLTs) in Chemotherapy Treatment Combination
时间窗: Up to 28 days
DLTs refer to toxicities experienced during the first 28 days of study treatment that have been judged to be clinically significant and related to study treatment in participant in Phase 1b. DLT was defined as any Grade 3 or greater AE including Grade 4 hematologic toxicity that does not resolve to Grade 2 and delays initiation of cycle 2 by more than 14 days, Grade 4 febrile neutropenia or associated infections, Grade 4 non-hematologic toxicity that does not resolve or decrease to Grade 2 within 1 week, Grade 4 infusion-related reaction (IRR), and recurrent Grade 3 or greater IRR despite optimal pretreatment regimen that was assessed as related to either magrolimab, rituximab, gemcitabine, or oxaliplatin and occurred during the 4-week DLT observation period. Any TEAE that was, in the opinion of the Clinical Trial Steering Committee, of potential clinical significance such that further dosing exposed participants to unacceptable risk, was considered a DLT.
Percentage of Participants Experiencing Treatment Emergent Adverse Events (TEAEs)
时间窗: Up to 7.2 years
TEAE's were defined as any AEs with an onset date on or after the study drug start date, no later than 30 days after last dose of any study drug or day before initiation of subsequent line of anti-cancer therapy, whichever is earlier, or the AEs leading to the discontinuation of the study drug. An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with use of an investigational product or other protocol imposed intervention, regardless of attribution.
Objective Response Rate (ORR) (Complete Response [CR] + Partial Response [PR]) as Defined by the Investigator According to the Lugano Classification for Lymphomas
时间窗: Up to 7.3 years
ORR:CR(complete metabolic response(CMR);complete radiological response(CRR)) or PR(partial metabolic response(PMR);partial radiologic response(PRR)).CMR:PET 5 point-scale(5PS) with 1(no uptake above background,2(uptake≤mediastinum),3(uptake\>mediastinum but≤liver)with/without residual mass;no new lesions;no fluorodeoxyglucose (FDG)-avid disease in bone marrow(BM).CRR:target nodes/nodal masses regressed ≤1.5cm in longest transverse diameter of lesion(LDi);no extra lymphatic disease sites;absent non-measured lesions(NMLs);organ enlargement to normal;no new sites;BM morphology normal.PMR:scores 4(uptake moderately\>liver),5(uptake markedly\>liver,new lesions)with reduced uptake from baseline \& residual mass;no new lesion;responding disease at interim/residual disease at end of treatment.PRR:≥50% decrease in sum of perpendicular diameters up to 6 target measurable nodes,extra-nodal sites;absent/normal,regressed,but no increase of NMLs;spleen regressed \>50% length beyond normal; no new sites.
