Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
Primary Objective:

* Dose Ranging Phase: To evaluate the efficacy of daily oral doses of 100, 200, and 400 mg SAR302503 in patients with PV and ET who are resistant or intolerant to hydroxyurea (per European LeukemiaNet criteria) for :

* Inducing absence of phlebotomy and a hematocrit below 45% for a minimum of 3 months in patients with polycythemia vera, and
* Reduction of platelet count to =400 x 10x9/L for a minimum of 3 months in patients with essential thrombocythemia.
* PV Dose Expansion Phase and ET Dose Ranging Phase (only 600 mg dose group): To evaluate the efficacy of daily oral SAR302503 in patients with PV and ET who are resistant or intolerant to hydroxyurea (per European LeukemiaNet criteria) for:

* Inducing absence of phlebotomy eligibility beginning at Day 1 of Cycle 4 visit and continuing through Day 1 of Cycle 6 visit in patients with PV, and
* Reduction of platelet count to =400 x 10x9/L beginning at Day 1 of Cycle 4 visit and continuing through Day 1 of Cycle 6 visit in patients with ET.

Secondary Objectives:

* To evaluate the safety of SAR302503.
* To evaluate the efficacy of SAR302503 in patients with PV who are resistant or intolerant to hydroxyurea for inducing absence of phlebotomy eligibility.
* To evaluate the efficacy of SAR302503 in patients with ET who are resistant or intolerant to hydroxyurea for reduction of platelet counts.
* To evaluate the efficacy of SAR302503 in inducing complete and partial responses beginning at Day 1 of Cycle 6 visit through Cycle 8.
* To evaluate splenic response as measured by spleen volume using MRI or CT.
* To evaluate the pharmacokinetics of SAR302503 after single and repeat doses.
* To evaluate the pharmacodynamics of SAR302503 as measured by changes in JAK2V617F allele burden in patients with JAK2V617F mutation, and STAT3 phosphorylation inhibition.
* To measure improvement in baseline myeloproliferative neoplasm (MPN)-associated symptoms, as well as overall impact on quality of life.
* To measure generic health-related quality of life and utility value using the EuroQol Group (EQ-5DTM) questionnaire.
