What was measured
The primary endpoint compares progression-free survival as a time to event endpoint from randomization between patients randomized to ixazomib and placebo maintenance in high risk multiple myeloma. Participants are considered a failure of the primary endpoint if they die or suffer from disease progression or if they initiate non-protocol anti-myeloma therapy. Disease progression was evaluated using the International Uniform Response Criteria. Participants must meet one of the criteria for disease progression specified in the protocol. The time to this event is the time from randomization to progression, death, or initiation of non-protocol anti myeloma therapy whichever comes first. The Kaplan-Meier estimator was used to estimate progression-free survival during the 2 year post-transplant follow-up period. Participants who were event-free at two years post-transplant are censored at that time.
Analysis population: All randomized participants were included in the primary endpoint 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 progression-free survival time post-randomization among randomized subjects receiving Ixazomib vs Placebo maintenance therapy during the 21 month period post-randomization. This was compared between treatment arms using a log rank test.
