Serum Concentration for Magrolimab in TN/U AML and TN MDS Participants
Time frame: Predose and/or after 1 hour of infusion (duration 3 hours (± 30 minutes) for 1mg/kg; 2 hours for 15 mg/kg, 30 mg/kg and 60 mg/kg) in Cycles (each cycle of 28 days) 1 to 7, 9, 11, 13, 15, on Days 1, 2, 3, 4, 8, 11, 15, 16, 17, 18, 22, EOT, Safety Follow-up
Population: The Pharmacokinetic (PK) Analysis Set included participants in All Enrolled Analysis Set, who took at least 1 dose of magrolimab and had at least 1 detectable postdose magrolimab concentration value reported by the PK laboratory at the given timepoint.~As per the pre-specified analysis, this outcome measure was applicable only for the TN/U AML and TN MDS cohorts. Data is reported according to the frequency of magrolimab administered: QW, Q2W, QW to Q2W for both TN/U AML and TN MDS cohorts.
