| Phase 1/Phase 2 |
Detailed Description
The proposed study is an open-label, single-arm, Phase-Ib/II trial to assess the efficacy of oral drug combination ruxolitinib and pomalidomide in primary and secondary MF patients. Dosages of the drugs are derived from previous Phase-I/II studies; ruxolitinib treatment will be started at 10 mg twice daily, whereas the dose of pomalidomide will be 0.5 mg once daily.
Dose reductions and discontinuations will be allowed in case of myelosuppressive effects.
Intra-patient dose escalation will be permitted for ruxolitinib to optimize efficacy of the therapeutic regimen; pomalidomide will be given in a permanent dosage of 0.5mg per day.
Treatment response will be evaluated continuously after each treatment cycle (1 cycle = 28 days) according to the IWG-MRT criteria expanded by the response criterion RCT-independency.
In case of progressive disease study therapy will be stopped; In patients showing response or stable disease, continuous therapy within the study is intended for a maximum of 12 treatment cycles; After completion of 12 treatment cycles, therapy can be continued if a measurable benefit of treatment is evident. This extension has to be discussed between the local and the principle investigator. Conditions leading to patient withdrawal from the study are detailed in the protocol "PATIENT WITHDRAWAL FROM STUDY PARTICIPATION".

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: ruxolitinib/pomalidomide Cohort 1 (Patient 1 - Patient 41): ruxolitinib treatment will be started at 10 mg twice daily up to 25 mg twice daily, whereas the dose of pomalidomide will be 0.5 mg once daily. Cohort 2 (Patient 42 - Patient 90): ruxolitinib treatment will be started at 10 mg twice daily up to 25 mg twice daily, whereas the dose of pomalidomide will be started at 0.5 mg once daily up to 2 mg once daily. |
Drug: INCB018424/CC-4047
Cohort 1: For patients (1-41) the starting dose of ruxolitinib in this trial is 10 mg twice daily po; pomalidomide will be administered at a permanent dose of 0.5 mg po once daily.
Cohort 2: For patients (42-90) the starting dose of ruxolitinib in this trial is 10 mg twice daily po; the starting dose of pomalidomide is 0.5 mg po once daily.

Outcome Measures
Primary Outcome Measures

Secondary Outcome Measures

overall survival
- Quality of life assessed by the Myeloproliferative Neoplasm Symptom [three years]
Quality of life assessed by the Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF Protocol 5/25/11), change in ECOG performance status from study entry to each visit where the variable is measured.
- Clinical Benefit - Assessment of each patient [three years]
Clinical Benefit: Lab / Clinical data: Stable disease (SD) plus hematologic improvement: prolongation of RBC transfusion intervals by ≥50% compared to baseline in transfusion dependent patients or ≥1 g/dL Hb increase in the absence of RBC transfusion dependency and/or Questionaire: Stable disease (SD) plus improvement of MF-associated symptoms: SD plus improvement of at least one MF-associated symptom according to the MPN-SAF / EORTC QLQ-C30 or FACT-Lym by a minimum of 50% and/or SD plus improvement of ≥ two MF-associated symptoms according the MPN-SAF / EORTC QLQ-C30 or FACT-Lym by a minimum of 25% each.
- Monthly Response assessment [three years]
Response criteria: Assessment according to the IWG-MRT (based on lab, clinical data): CR / PR / CI / PD / SD / RD/ RBC-TD / RBC-TI
