- Maximum Tolerated Dose (MTD) and Recommended MTD of Dasatinib in Combination With Bortezomib and Dexamethasone [ Time Frame: Days 1 to 21 ]MTD is defined as the dose level combination below the dose level that produces a dose-limiting toxicity in at least 2 out of 6 or fewer participants in that cohort. If MTD is not reached, the recommended MTD is the maximum dose that the participants received.
- MTD and Recommended MTD of Bortezomib in Combination With Dasatinib and Dexamethasone [ Time Frame: Days 1 to 21 ]MTD is defined as the dose level combination below the dose level that produces a dose-limiting toxicity in at least 2 out of 6 or fewer participants in that cohort. If MTD is not reached, the recommended dose is the maximum dose that the participants received.
- Best Overall Tumor Response Rate (RR) As Assessed Using International Uniform Response Criteria for Multiple Myeloma and Criteria of the European Bone Marrow Transplant Registry [ Time Frame: Day 1 until last tumor assessment (maximum reached: 9 months) ]S=serum; U=urine; MP=M-protein; ST=soft tissue, PC=plasmacytomas; IF=immunofixation; BL=baseline. RR calculated on best response any time. CR=MP undetectable by IF, ≤5% plasma cells in bone marrow, and no ST PC. VGPR=MP detectable by IF, or ≥90% drop in S MP and U MP<100 mg/24h. PR= ≥50% drop in S MP and ≥90% drop in U MP or U protein <200 mg/24h, ≥50% drop in BL ST PC size. MR= ≥25% to <50% drop in S MP and ≥50% to <90% drop in U MP and ≥25% to <50% drop in BL ST PC. SD=Not CR, VGPR, PR, or MR. PD= ≥25% rise in S or U M-component; new/increased size of bone lesions, ST PC, or hypercalcemia.
- Duration of Response [ Time Frame: First occurrence of response to disease progression or death, whichever occurred first (maximum reached: 12.2 months) ]Duration of response calculated for those with best response=CR (M-protein [MP] undetectable by immunofixation [IF], ≤5% plasma cells in bone marrow, no soft tissue plasmacytomas); VGPR (MP detectable by IF, or ≥90% drop in serum [S] MP and urine [U] MP<100 mg/24h); PR(≥50% drop in S MP and ≥90% drop in U MP or U protein <200 mg/24h, ≥50% drop in BL ST PC size); or MR (≥25% to <50% drop in S MP and ≥50% to <90% drop in U MP and ≥25% to <50% drop in BL ST PC). Duration of response calculated from day criteria for CR, VGPR, PR, and MR were met until progression or death, whichever came first.
- Progression-free Survival [ Time Frame: Day 1 to disease progression or death, whichever came first (maximum reached: 14 months) ]Progression-free survival was defined as the time from start of treatment until progression or death, whichever occurred first. Participants were to be followed-up for 12 months following the last dose of dasatinib for progression and survival. PFS was analyzed for the all-treated population.
- Number of Participants With Death As Outcome, Serious Adverse Events (SAEs), Drug-related SAEs, Drug-related Adverse Events (AEs) Leading to Discontinuation, AEs Leading to Discontinuation, AEs, and Drug-related AEs by Grade [ Time Frame: Continuously from Day 1 until last day of study medication + 30 days (maximum reached: 10 months) ]An AE is any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment. An SAE is any unfavorable medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency or abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Drug-related=possibly, probably, or certainly related to or of unknown relationship to study treatment. Grade 3=severe; Grade 4=life-threatening.
