Determining the Feasibility of MLN9708 as Maintenance After Allogeneic Stem Cell Transplant for Multiple Myeloma

"Patients will be enrolled between Days 45 and 120 after allogeneic transplant and will receive MLN9708 orally (PO) as monotherapy on Days 1, 8, and 15 of each 28-day cycle for 6 cycles. Up to 18 patients will be enrolled in a dose-escalation phase to determine the maximum tolerated dose (MTD).~Dose-Escalation Phase: MLN9708 will be administered orally (PO) as monotherapy. Dosing will start at 2.3 mg. If acceptable tolerability is demonstrated, escalations will be made to 3 mg and to a maximum-planned dose (MPD) of 4 mg."
