What was measured
Disease progression was evaluated using the International Uniform Response Criteria. Participants in sCR/CR must meet at least one of the criteria for disease progression specified in the protocol for sCR/CR participants; those not in sCR/CR must meet at least one of the disease progression criteria specified in the protocol for those not in sCR/CR. The cumulative incidence of progression from randomization will be estimated for each treatment arm using the Aalen-Johansen estimator, with death in remission treated as a competing risk. Initiation of anti-myeloma therapy will be considered evidence of progression. Participants who were event-free at two years post-transplant are censored at that time.
Analysis population: All randomized participants were included in the analysis.
Groups in this outcome
Ixazomib Maintenance
Allogeneic HSCT and Fludarabine/Melphalan/Bortezomib conditioning followed by Ixazomib maintenance Allogeneic HSCT: Eligible patients with a Human Leukocyte Antigen (HLA)-matched related or unrelated donor will undergo allogeneic hematopoietic stem cell transplant at Day 0. For GVHD prophylaxis, patients will be given Tacrolimus from Day -3 until at least 6 months following initiation, at an intravenous daily dose of 0.015 mg/kg. This will be combined with an intravenous administration of Methotrexate at 5 mg/m2 on Days +1, +3, +6, and +11. Fludarabine: Patients will receive conditioning treatment before and after HSCT. Fludarabine will be given at 30 mg/m2 intravenously on Day -6 through Day -3. Melphalan: Melphalan will be given at 70 mg/m2 intravenously on Days -4 and -3. Bortezomib: Bortezomib will be administered at 1.3 mg/m2 intravenously on Day -3. Ixazomib: Between 60 and 120 days following HSCT, patients randomized to the experimental arm will receive Ixazomib maintenance. Maintenance will begin at 3-mg oral doses on Days 1, 8, and 15 of a 28-day cycle. This will increase to 4-mg doses on the same cycle schedule, following successful completion of 3 cycles at the previous dosage, for a total of 12 cycles.
Placebo
Allogeneic HSCT and Fludarabine/Melphalan/Bortezomib conditioning followed by placebo maintenance. Allogeneic HSCT: Eligible patients with a Human Leukocyte Antigen (HLA)-matched related or unrelated donor will undergo allogeneic hematopoietic stem cell transplant at Day 0. For GVHD prophylaxis, patients will be given Tacrolimus from Day -3 until at least 6 months following initiation, at an intravenous daily dose of 0.015 mg/kg. This will be combined with an intravenous administration of Methotrexate at 5 mg/m2 on Days +1, +3, +6, and +11. Fludarabine: Patients will receive conditioning treatment before and after HSCT. Fludarabine will be given at 30 mg/m2 intravenously on Day -6 through Day -3. Melphalan: Melphalan will be given at 70 mg/m2 intravenously on Days -4 and -3. Bortezomib: Bortezomib will be administered at 1.3 mg/m2 intravenously on Day -3. Placebo: Between 60 and 120 days following HSCT, patients randomized to the control group will be given 3 mg of placebo orally on Days 1, 8, and 15 of a 28-day cycle. This will increase to 4-mg doses on the same cycle schedule following successful completion of 3 cycles of placebo maintenance at the 3-mg dose. This will continue for a total of 12 cycles.

Source statistical analyses
- group Description
- The null hypothesis is that there is no difference in the proportions of participants with progression between the Ixazomib and Placebo arms during 21 months post-randomization, with death prior to progression treated as a competing risk. Cumulative incidences are compared between treatment arms using Gray's test.
