Experimental: Ruxolitinib then Ruxolitinib + Dexamethasone
Patients received ruxolitinib 25 mg orally twice daily (bid) in each treatment cycle of 28 days. For those patients who had disease progression at any time or stable disease for 3 cycles and did not meet a withdrawal criterion, or withdrew consent, then 40 mg of dexamethasone was added to ruxolitinib on Days 1 to 4, 9 to 12, and 17 to 20 of four 28-day cycles. After the 4th cycle, 40 mg of dexamethasone was administered only on Days 1 to 4 of each subsequent cycle. Patients could continue to receive monotherapy or combination therapy indefinitely as long as no withdrawal criterion was met, did not have progressive disease and were receiving some clinical benefit.
Drug: Ruxolitinib 25 mg
Ruxolitinib was supplied as 5 and 25 mg tablets.
Other Name: INCB018424Drug: Dexamethasone 40 mg
Dexamethasone was obtained commercially by Investigators in tablet strengths of 20 or 40 mg.
- Number of Responders According to the International Uniform Response Criteria for Multiple Myeloma [ Time Frame: Day 1 of Cycles 2, 3, and 4 and then every 3 months thereafter (up to 25 months). ]A responder is defined as a patient with a complete response (negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and ≤ 5% plasma cells in bone marrow) or a partial response (≥ 50% reduction of serum M-protein and reduction in 24 h urinary M-protein by ≥ 90% or to < 200 mg per 24 h).
- Time to Disease Progression According to the International Uniform Response Criteria for Multiple Myeloma [ Time Frame: Day 1 of Cycles 2, 3, and 4 and then every 3 months thereafter (up to 25 months). ]
Progressive Disease requires 1 or more of the following:
Increase of ≥ 25% from baseline in:
Serum M-component and/or (increase ≥ 0.5 g/dL).
Urine M-component and/or (increase ≥ 200 mg/24 h).
In patients without measurable serum and urine M-protein levels the difference between involved and uninvolved FLC levels increase must be > l0 mg/dL.
Bone marrow plasma cell percentage ≥ 10%.
Definite development of new or increase in the size of existing bone lesions or soft tissue plasmacytomas.
Development of hypercalcemia.
