Descriptive Information
Brief Title  ICMJE Phase III Study of SAR302503 in Intermediate-2 and High Risk Patients With Myelofibrosis
Official Title  ICMJE A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled, 3-Arm Study of SAR302503 in Patients With Intermediate-2 or High-Risk Primary Myelofibrosis, Post-Polycythemia Vera Myelofibrosis, or Post-Essential Thrombocythemia Myelofibrosis With Splenomegaly
Brief Summary

Primary Objective:

  • To evaluate the efficacy of daily oral doses of 400 mg or 500 mg of SAR302503 (Investigational Medicinal Product, IMP) compared to placebo in the reduction of spleen volume as determined by magnetic resonance imaging (MRI) (or computed tomography scan in patients with contraindications for MRI).

Secondary Objectives:

  • To evaluate the effect on Myelofibrosis (MF)-associated symptoms (key MF symptoms) as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF) diary.
  • To evaluate the Overall Survival of patients treated with either 400 mg/day or 500 mg/day of IMP as compared to placebo.
  • To evaluate the Progression Free Survival of patients treated with either 400 mg/day or 500 mg/day of IMP as compared to placebo.
  • To evaluate the durability of splenic response.
  • To evaluate the safety of IMP.
Detailed Description

The expected duration of a patient's 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 End Of Treatment (EOT) visit, which should be performed at least 30 days following the last administration of IMP or placebo.

Patients who continue to benefit clinically will be allowed to remain on IMP or placebo beyond the 6-month treatment period until the occurrence of disease progression or unacceptable toxicity.

  • MF classified as high-risk or intermediate-risk level 2, as defined by modified IWG-MRT criteria (IPSS) (according to Cervantes F. et. al.; at screening).
  • Enlarged spleen, palpable at least 5 cm below costal margin.
  • At least 18 years of age.
  • Eastern Cooperative Oncology Group performance status of 0, 1, or 2 at study entry.
  • The following laboratory values within 14 days prior to the initiation of IMP or placebo:

Patients who have had exposure to hydroxyurea (eg, hydrea) in the past may be enrolled into the study as long as it has not been administered within 14 days prior to initiation of IMP or placebo.

  • Prior treatment with a Janus Kinase 2 (JAK2) inhibitor.
  • Known active (acute or chronic) Hepatitis A, B, or C; and hepatitis B and C carriers
  • AST or ALT ≥2.5 x ULN
  • Total Bilirubin:
  • Exclude if ≥3.0 x ULN
  • Patients with total bilirubin between 1.5-3.0 x ULN must be excluded if the direct bilirubin fraction is ≥25% of the total
  • Prior history of chronic liver disease (eg, chronic alcoholic liver disease, autoimmune hepatitis, sclerosing cholangitis, primary biliary cirrhosis, hemachromatosis, non-alcoholic steatohepatitis [NASH])
