Brief Summary:
Primary Objective:
- To evaluate the efficacy of once daily dose of SAR302503 in subjects previously treated with ruxolitinib and with a current diagnosis of intermediate-1 with symptoms, Intermediate-2 or high-risk primary myelofibrosis (PMF), post-polycythemia vera myelofibrosis (Post-PV MF), or post-essential thrombocythemia myelofibrosis (Post-ET MF) based on the reduction of spleen volume at the end of 6 treatment cycles;
Secondary Objectives:
- To evaluate the effect of SAR302503 on Myelofibrosis (MF) associated symptoms as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF) diary
- To evaluate the durability of splenic response
- To evaluate the splenic response to SAR302503 by palpation at the end of Cycle 6
- To evaluate the splenic response to SAR302503 at the end of Cycle 3
- To evaluate the effect of SAR302503 on the Janus kinase 2 (JAK2) V617F allele burden
- To evaluate the safety and tolerability of SAR302503 in this population
- To evaluate plasma concentrations of SAR302503 for population PK analysis, if warranted
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Hematopoietic Neoplasm | Drug: SAR302503 | Phase 2 |
The expected duration of the treatment in this study is approximately 8 months, based on a maximum 28-day screening period, followed by a 6-month (6-cycle) treatment period, and an EOT visit for subjects who will not continue the treatment after completing the 6 cycles of SAR302503, or discontinue the treatment early for any reasons as well as a follow-up visit which should occur 30 days after the last administration of SAR302503. Patients who continue to benefit clinically will be allowed to remain on study medication beyond the 6-month treatment period until the occurrence of disease progression or unacceptable toxicity.

Primary Outcome Measures :
- Response Rate (RR), defined as the proportion of subjects who have a ≥35% reduction from baseline in volume of spleen at the end of Cycle 6 as measured by Magnetic Resonance Imaging (MRI) (or CT scan in subjects with contraindications for MRI) [ Time Frame: 6 months ]
Secondary Outcome Measures :
- Symptom Response Rate (SRR): Proportion of subjects with a ≥50% reduction from baseline to the end of Cycle 6 in the total symptom score using the modified MFSAF [ Time Frame: 6 months ]
- Duration of spleen response, measured by MRI (or CT scan in subjects with contraindications for MRI) [ Time Frame: 6 months ]
- Proportion of subjects with a ≥50% reduction in length of spleen by palpation from baseline at the end of Cycle 6 [ Time Frame: 6 months ]
- Response Rate at the end of Cycle 3, defined as the proportion of subjects who have a ≥35% reduction from baseline in volume of spleen at the end of Cycle 3 as measured by MRI (or CT scan in subjects with contraindications for MRI) [ Time Frame: 6 months ]
- Percent change of spleen volume at the end of Cycles 3 and 6 from baseline as measured by MRI (or CT scan in subjects with contraindications for MRI) [ Time Frame: 6 months ]
- Safety, as assessed by clinical, laboratory, ECG, and vital sign events; graded by the NCI CTCAE v4.03 [ Time Frame: approximately 5 years ]
- Plasma concentrations of SAR302503 [ Time Frame: 4 months ]
- The effect of SAR302503 on the JAK2V617F allele burden [ Time Frame: 2 years ]
