GR 3: anemia (hemolytic anemia that is medically significant tis considered a DLT), indirect/unconjugated hyperbilirubinemia, electrolyte abnormalities, elevation in alanine aminotransferase, aspartate aminotransferase, or alkaline phosphatase that resolved to ≤ Grade 2 with supportive care within 1 week and is not associated with other clinically significant consequences; nausea, vomiting, or diarrhea that resolved to ≤ Grade 2 with supportive care within 72 hours; fatigue that resolved to ≤ Grade 2 within 2 weeks on study; drug-related infusion reactions in the absence of an optimal pretreatment regimen; tumor lysis syndrome or electrolyte disturbances, hypomagnesemia, that resolved to ≤ Grade 2 or baseline within 1 week;
GR 3 or 4: lymphopenia or leukopenia.Percentage of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs) From first dose date up to last dose date plus 30 days (maximum: 15.3 months) An AE was any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. An AE was any unfavorable and unintended sign, symptom, disease, and/or laboratory or physiological observation that may or may not be related to the investigational medicinal product. A TEAE was defined as AEs worsening or occurring during or after a participant's first exposure to study drug and within 30 days after the last administration of study drug or initiation of new anticancer therapy, whichever occurred first.
Objective Response Rate (ORR) as Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) From Screening until 38.89 months (assessed on Day 1 of Cycle 3 then every 8 weeks [Q8W] from Cycle 5 onwards up to 38.89 months; 1 cycle = 4 weeks) Objective response rate was defined as the percentage of participants with objective response which consisted of complete response (CR)+ partial response (PR) determined by RECIST v 1.1. CR: Disappearance of all target and all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (\< 10 mm short axis). Any pathological lymph nodes (whether target or non-target) had a reduction in short axis to \< 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
- Secondary Outcome Measures
Name Time Method Disease Control Rate (DCR) as Assessed by RECIST v1.1 From Screening until 38.89 months (assessed on Cycle 3 Day 1 then every 8 weeks from Cycle 5 onwards up to 38.89 months; 1 cycle = 4 weeks) DCR was defined as the percentage of participants with disease control which consisted of CR+PR+SD. CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had a reduction in short axis to \< 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum diameters measured while on study. PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum measured while on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Unequivocal progression of existing non-target lesions.
Duration of Response (DOR) as Assessed by RECIST v1.1 From first objective response until documented PD (assessed on Cycle 3 Day 1 then every 8 weeks from Cycle 5 onwards up to 38.89 months; 1 cycle = 4 weeks) DOR was measured from when the first (objective) response was met (i.e., CR or PR) until the first date of objectively documented PD. Participants who did not have objectively PD was censored at their last documented progression-free date. CR: Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had a reduction in short axis to \< 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum measured while on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Unequivocal progression of existing non-target lesions. Kaplan Meier estimate was used for analysis.
Percentage of Participants With Anti-drug Antibodies (ADA) Baseline; post-treatment (assessed continuously up to 30 days after last dose; maximum 15.3 months ) Percentage of Participants With Positive ADA at any timepoint was reported.
PK Parameter: Tmax of Magrolimab Pre-magrolimab dose (within 12 hours) and 1-hour post-magrolimab dose (infusion duration = approximately 3 hours on Day 1 and 2 hours on other days) on Days 8 (Cycle 1 Day 8) and 29 (Cycle 2 Day 1) (1 cycle = 4 weeks) Tmax is defined as the time (observed time point) of Cmax.
Progression Free Survival (PFS) as Assessed by RECIST v1.1 From first dose until documented PD/death (assessed on Cycle 3 Day 1 then every 8 weeks from Cycle 5 onwards up to 38.89 months; 1 cycle = 4 weeks) PFS was measured from first dose until the first date of objectively documented PD or death. Participants who did not have objectively documented PD and not died was censored at their last documented progression-free date. PD: At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum measured while on study (this included the baseline sum if that was the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Unequivocal progression of existing non-target lesions. Kaplan Meier estimate was used for analysis.
Pharmacokinetic (PK) Parameter: Cmax of Magrolimab Pre-magrolimab dose (within 12 hours) and 1-hour post-magrolimab dose (infusion duration = approximately 3 hours on Day 1 and 2 hours on other days) on Days 1 (Cycle 1 Day 1), 8 (Cycle 1 Day 8), and 29 (Cycle 2 Day 1) (1 cycle = 4 weeks) Cmax is defined as the maximum concentration of drug.

Overall Survival (OS) From first dose until death (assessed on Cycle 3 Day 1 then every 8 weeks from Cycle 5 onwards up to 38.89 months; 1 cycle = 4 weeks) OS was measured from first dose until death. Participants who did not die were censored at their last known alive date. Kaplan Meier estimate was used for analysis.
PK Parameter: AUClast of Magrolimab Pre-magrolimab dose (within 12 hours) and 1-hour post-magrolimab dose (infusion duration = approximately 3 hours on Day 1 and 2 hours on other days) on Days 8 (Cycle 1 Day 8) and 29 (Cycle 2 Day 1) (1 cycle = 4 weeks) AUClast is defined as the concentration of drug from time zero to the last observable concentration.
