A Phase Ib, Open-label, Multi-center, Two-arm, Dose-finding Study to Assess Safety and Efficacy of the Oral Combination or INC424 (INC424) and BKM120 in Patients With Primary Myelofibrosis (PMF), Postpolycythemia Vera-myelofibrosis (PPV-MF), or Post-essential Thrombocythemia-myelofibrosis (PET-MF)

简要总结
The purpose of this phase Ib clinical trial is to evaluate the safety of the combination of INC424 and BKM120 in the myelofibrosis population and to establish the maximum tolerated dose and or the Recommended Phase II dose of the combination guided by the Bayesian dose escalation model. INC424 has shown efficacy in myelofibrosis (MF) and is approved in the US and EU for the treatment of MF. BKM120 is a PI3K inhibitor. Preclinical and early clinical experience support inhibition of the PI3K/mTOR pathway in MF as aberrant activation of the pathway has been observed in MF models and may contribute to the pathogenesis of the disease.

研究组 & 干预措施
JAK Inhibitor Naive
Two treatment periods applicable to all patients; Treatment Period (6 cycles / 28 days per cycle) and Extension Period ( 6 or more cycles of 28 days, with visits every 28days for 6 cycles and then visits every 12 weeks) following the treatment period dependent on patient continued eligibility. Two Study Phases: Dose Escalation Phase to determine maximum tolerated dose (MTD) / Recommended Phase II dose (RPIID) & an Expansion Phase

结局指标
主要结局
Incidence of dose limiting toxicities
时间窗: baseline, when the maximum tolerated dose is established.
The incidence of dose limiting toxicities will be analyzed to establish the maximum tolerated dose. To assess the maximum tolerated dose, labs and adverse events are monitored.
次要结局
- Severity of serious adverse events(after each cohort is enrolled at baseline until the maximum tolerated dose is established)
- Laboratory test values including Imaging (electrocardiograms (ECGs), abdominal MRI/CT, ECHO/MUGA(Day 1, 2, 5, 8, 11, 18, 22, 25 of cycle 1, weekly in cycle 2, then at every scheduled visit including End of treatment visit)
- Maximum plasma concentration time (Tmax)(pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 24 hours on days 2 and 8)
- Duration of serious adverse events(after each cohort is enrolled at baseline until the maximum tolerated dose is established)
- Area under the plasma concentration time curve (AUC)(pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 24 hours on days 2 and 8)
- Maximum plasma concentration (Cmax)(pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 24 hours on days 2 and 8)
- Frequency of adverse events(after each cohort is enrolled at baseline until the maximum tolerated dose is established)
- Frequency of serious adverse events(after each cohort is enrolled at baseline until the maximum tolerated dose is established)
- Abnormalities in vital signs(baseline, days 2, 8, 15, 22 of cycle 1, day 1 and 15 at Cycle 2, Day 1 from cycle 3 to 12, day 28 on Cycle 12 and every 12 weeks from Week 60 to 96 and at End of treatment)
- Duration of adverse events(after each cohort is enrolled at baseline until the maximum tolerated dose is established)
