Conditions: Multiple Myeloma
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 13
Healthy volunteers: no

Brief summary:
The purpose of this study was to determine clinical efficacy and safety of ruxolitinib (INCB018424), a small molecule Janus kinase 2 (JAK2)-inhibitor, in patients with refractory or relapsed multiple myeloma.

Detailed description:
The protocol was originally designed as a Simon two stage but after it was determined that the initial 13 patients enrolled did not meet the definition of a 'responder' according to the International Uniform Response Criteria for multiple myeloma the protocol was amended to allow patients who had disease progression at any time or stable disease for 3 cycles and did not meet a withdrawal criterion or had withdrawn consent to have 40 mg of dexamethasone added to their dose of ruxolitinib.

Arms:
arm 1: 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.

Interventions: intervention 1: Ruxolitinib 25 mg intervention 2: Dexamethasone 40 mg
Intervention descriptions: intervention 1: Ruxolitinib was supplied as 5 and 25 mg tablets. intervention 2: Dexamethasone was obtained commercially by Investigators in tablet strengths of 20 or 40 mg.
