Magrolimab Monotherapy or Magrolimab in Combination With Azacitidine in Participants With Hematological Malignancies

 Acute Myeloid Leukaemia (AML) / Posted 1 year ago

The primary objectives of this study are:

  • To confirm the safety and tolerability of magrolimab monotherapy in a relapsed/refractory (R/R) acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) population, and of magrolimab in combination with azacitidine in previously untreated participants with AML or MDS and participants with R/R AML and MDS
  • To evaluate the efficacy of magrolimab monotherapy in R/R AML/MDS, and of magrolimab in combination with azacitidine in previously untreated participants with AML/MDS, or R/R AML/MDS as measured by complete remission (CR) rate for participants with AML and higher-risk MDS, and duration of complete response for participants with AML and higher-risk MDS, and duration of CR for participants with AML and higher-risk MDS
  • To evaluate the safety, tolerability, and efficacy of magrolimab monotherapy or combination with azacitidine in low-risk MDS participants as measured by red blood cell (RBC) transfusion independence rate
  • Inclusion Criteria : Ages Eligible for Study: 18 Years and older (Adult, Older Adult) Sexes Eligible for Study: All Accepts Healthy Volunteers: No
    • Meets the criteria below for the appropriate cohort: 1. Relapsed/Refractory Cohorts: Pathologically confirmed relapsed or refractory (primary refractory and/or relapsed refractory) AML or confirmed intermediate, high, or very high risk MDS that is relapsed, refractory or intolerant to conventional therapy 2. Treatment-naive/ Unfit Cohorts: Previously untreated individuals with histological confirmation of AML who are ineligible for treatment with a standard cytarabine and anthracycline induction regimen; or previously untreated individuals with intermediate, high, or very high risk MDS. Prior and concurrent therapy with hydroxyurea, oral etoposide, erythroid and/or myeloid growth factors is allowed. 3. Rollover Cohort: Individuals on active magrolimab therapy on the Phase 1 AML (SCI-CD47-002; NCT02678338) trial who are deriving clinical benefit by Investigator assessment 4. RBC transfusion dependent low risk MDS cohort: Transfusion-dependent MDS individuals who are very low or low risk by IPSS-R with previous treatment with an erythroid stimulating agent or lenalidomide.
