简要总结

The primary purpose is to determine the safety and tolerability of belantamab mafodotin in combination with nirogacestat, pomalidomide, and dexamethasone and to establish the recommended Phase 2 dose for combination treatment to explore in the cohort expansion (CE) phase in participants with RRMM. This study is a sub study of the Master protocol (NCT04126200).

•Participants with prior treatment with an investigational agent within 14 days or 5 half-lives of receiving the first dose of study drugs, whichever is shorter.

•Participants who have received transfusion of blood products within 2 weeks before the first dose of study drug.
•Participants must not receive live attenuated vaccines within 30 days prior to first dose of study treatment or whilst receiving belantamab mafodotin +- partner agent in any sub-study arm of the platform trial and for at least 70 days following last study treatment.
•Participants with presence of active renal condition (infection, requirement for dialysis or any other condition that could affect participant's safety). Participants with isolated proteinuria resulting from MM.
•Participants with known human immunodeficiency virus (HIV) infection, unless the participant can meet all criteria: a) established anti-retroviral therapy for at least 4 weeks and HIV viral load<400 copies/milliliter (mL) b) cluster of differentiation 4 plus (CD4+) T-cell (CD4+) counts >= 350 cells/microliter (µL) c) No history of Acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections within the last 12 months in which case the participant would be eligible for CE Phase only. For participants receiving nirogacestat, HIV drugs that are strong Cytochrome P450 3A4 (CYP3A4) inhibitors are prohibited. HIV drugs that are moderate CYP3A4 inhibitors, while permitted, should be co-administered with caution and must be accompanied by nirogacestat dose modifications.
•Participants with uncontrolled small and/or large intestinal disease.
•Participants with uncontrolled skin disease.
•Participants with any condition causing hypophosphatemia, hypokalemia or hypomagnesemia which is refractory to electrolyte replacement.
•Participants with previous administration of a gamma secretase inhibitor.
•Participants with concomitant administration of a strong CYP3A4 inhibitor or inducer.
•Participants with active or history of venous thromboembolism within the past 3 months.
•Participants with evidence of active mucosal or internal bleeding.
•Participants with contraindications to or are unwilling to undergo protocol-required anti-thrombotic prophylaxis or unable to tolerate antithrombotic prophylaxis.
•Participants who discontinued prior treatment with pomalidomide due to intolerable adverse events.
