EXPERIMENTAL: IV busulfan
Intravenous (IV) busulfan was administered as a single daily 3-hour continuous infusion based on the PK-directed dose recommendation for 4 days beginning on Day -5 followed by a single bortezomib 1.3 mg/m^2 dose administered as a 3 to 5-second bolus IV injection on Day -1 prior to HSCT.

Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Overall Disease Response at Month 6
Time Frame: 6 Months
|
The percentage of participants reported in each disease category by International Myeloma Working Group (IMWG) uniform response criteria for Multiple Myeloma 6 months after autologous Hematopoietic stem cell transplant.
Overall Disease Response categories were: [stringent Complete Response (sCR)=CR + normal Free Light Chain (FLC) ratio + absence of clonal cells in bone marrow], [Complete Response (CR)=Negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and ≤5% plasma cells in bone marrow], [Very Good Partial Response (VGPR)=Serum and urine M-protein detectable by immunofixation but not on electrophoresis or 90% or greater reduction in serum M-protein + urine M-protein level <100 mg/24 hour], [Partial Response (PR)=≥50% reduction of serum M-protein and reduction in 24 hour urine M-protein by ≥90% or to <200 mg per 24 hour], [Stable Disease (SD)=Not meeting criteria for CR, VGPR, PR or progressive disease] or [Progressive Disease (PD)].

PD was defined as an Increase of ≥25% from the lowest response value in any one or more of the following: 1)Serum M-component and/or (the absolute increase must be ≥0.5 g/dL), 2)Urine M-component and/or (the absolute increase must be ≥200 mg/24 hr), 3)In patients without measurable serum and urine M-protein levels; the difference between involved and uninvolved FLC levels.
The absolute increase must be >10 mg/dL, 4)Bone marrow plasma cell percentage; the absolute percentage must be ≥10%, 5)Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas and/or 6)Development of hypercalcaemia that can be attributed solely to the plasma cell proliferative diso

Percent Change in IV Busulfan Dose
Time Frame: Baseline (Day -12 to -9), Day -5
|
The percent change in dose is relative to the busulfan dose administered at the Baseline Visit (Day -12 to -9) when a dose of 0.8 mg/kg was administered and on Day -5 when the Seattle Cancer Care Alliance recommended PK-adjusted dose was administered.
|
Baseline (Day -12 to -9), Day -5
|
Ratio Area Under Curve (AUC)/Target AUC
Time Frame: Baseline (Day -12 to -9), Day -5
|
A test dose of IV busulfan 0.8 mg/kg was infused at Baseline (Day -12 to -9) to verify a target busulfan integrated AUC of 20,000 μM*min with a range of 16,000 to 24,000.
If necessary the dose could be adjusted.
The PK-directed dose recommendation based on the test dose was administered at Day -5.
Blood samples for PK analysis were collected at 0, 15, 30 minutes after the End of Infusion and 240, 300, 360 minutes after start of the infusion.
Gas chromatography with mass selective detection (GC-MS) was used to determine the busulfan level in plasma.
The ratio was calculated: AUC/Target AUC.
