Overview
Brief Summary
To determine the safety and tolerability of alnuctamab in combination with mezigdomide in participants with RRMM (primary - all phases). To determine the recommended Phase 2 dose (RP2D) and schedule of mezigdomide when administered in combination with alnuctamab in participants with RRMM (Phase 1b only). To evaluate the preliminary efficacy of alnuctamab in combination with mezigdomide in comparison to alnuctamab monotherapy in participants with RRMM (Phase 2a only).

Outcomes
Primary Outcomes
All phases: Type, frequency, seriousness, and severity of all aAEs;. To be assessed continuously for all participants until 80 days after the last dose of alnuctamab or 28 days after the last dose of mezigdomide, whichever is later.
All phases: Type, frequency, seriousness, and severity of all aAEs;. To be assessed continuously for all participants until 80 days after the last dose of alnuctamab or 28 days after the last dose of mezigdomide, whichever is later.
Phase 1b: Establish RP2D and dosing schedule of mezigdomide in combination with alnuctamab for Phase 2a expansion. To be assessed at end of Phase 1.
Phase 1b: Establish RP2D and dosing schedule of mezigdomide in combination with alnuctamab for Phase 2a expansion. To be assessed at end of Phase 1.
Phase 2a: Overall response rate. To be assessed every cycle for all participants starting at Cycle 2 Day 1 until end of treatment. Participants in efficacy follow-up may be assessed every 8 weeks until dprogression, withdrawal of consent, death, or initiation of new systemic anticancer therapies.
Phase 2a: Overall response rate. To be assessed every cycle for all participants starting at Cycle 2 Day 1 until end of treatment. Participants in efficacy follow-up may be assessed every 8 weeks until dprogression, withdrawal of consent, death, or initiation of new systemic anticancer therapies.
Secondary Outcomes
- All phases: Other myeloma response measures such as very good partial or better rate and complete response rate; time-to-response (the time it takes for a myeloma response after treatment) and duration of response. These will be assessed for all participants starting at Cycle 2 Day 1. Other measures include progression-free survival (the amount of time after starting treatment that the cancer does not worsen) and overall survival, both of which will be assessed continuously
- Phase 1b: overall response rate. To be assessed every cycle for all participants starting at Cycle 2 Day 1 until end of treatment. Participants in efficacy follow-up may be assessed every 8 weeks until dprogression, withdrawal of consent, death, or initiation of new systemic anticancer therapies.
