Multiple Myeloma Clinical Trial

Study of Magrolimab Combinations in Participants With Relapsed/Refractory Multiple Myeloma

Summary

The primary objective of this study for the Safety Run-in Cohorts is to evaluate the safety and tolerability of magrolimab in combination with other anticancer therapies and to determine the recommended Phase 2 dose (RP2D) of magrolimab in participants with relapsed/refractory multiple myeloma (MM) for the following combinations: magrolimab + daratumumab, magrolimab + pomalidomide + dexamethasone, and magrolimab + bortezomib + dexamethasone.

The primary objective of this study for the Dose Expansion Cohorts is to evaluate the efficacy of magrolimab in combination with other anticancer therapies in participants with relapsed/refractory multiple myeloma as determined by objective response rate (ORR).

Magrolimab in Combination with Daratumumab: In addition to fulfilling the inclusion criteria for all individuals, individuals who are assigned to receive magrolimab in combination with daratumumab should fulfill the following:

Must have received at least 3 previous lines of therapy for MM including an IMiD such as lenalidomide and a PI such as bortezomib.
Individuals must have not had prior anti-CD38 antibody therapy for at least 6 months prior to enrollment.
No prior history of discontinuation of daratumumab due to toxicity.

Magrolimab in Combination with Pomalidomide and Dexamethasone: In addition to fulfilling the inclusion criteria for all Individuals, Individuals who are assigned to receive magrolimab in combination with pomalidomide and dexamethasone should fulfill the following:

Must have received at least 3 previous lines of therapy for MM including an IMiD such as lenalidomide and a PI such as bortezomib.
Prior treatment with pomalidomide is allowed if the Individual achieved at least a PR to the most recent pomalidomide therapy and will have had at least a 6-month treatment-free interval from the last dose of pomalidomide until first study treatment.
No prior history of discontinuation of pomalidomide due to toxicity.

Magrolimab in Combination with Bortezomib and Dexamethasone: In addition to fulfilling the inclusion criteria for all individuals, individuals who are assigned to receive magrolimab in combination with bortezomib and dexamethasone should fulfill the following:

Must have received at least 1 previous line of therapy for MM including an IMiD such as lenalidomide and a PI such as bortezomib.
Prior treatment with a PI, including bortezomib, is allowed if the Individual achieved at least a PR to the most recent prior PI therapy, and will have had at least a 6-month PI treatment-free interval from the last dose until first study treatment.
No prior history of discontinuation of bortezomib due to toxicity.
