Phase III Study of SAR302503 in Intermediate-2 and High Risk Patients With Myelofibrosis

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.

Phase 3


Inclusion criteria:

   - Diagnosis of Primary Myelofibrosis (MF) or Post-Polycythemia Vera MF or Post-Essential
   Thrombocythemia MF, according to the 2008 World Health Organization and International
   Working Group of Myelofibrosis Research and Treatment (IWG-MRT) criteria.

   - 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

   - Absolute Neutrophil Count (ANC) ≥1.0 x 10exp9/L

   - Platelet count ≥50 x 10exp9/L

   - Serum creatinine ≤1.5 x Upper Limit of Normal (ULN)

   - Serum amylase and lipase ≤1.5 x ULN

Exclusion criteria:

   - Splenectomy.

   - Any chemotherapy (eg, hydroxyurea), immunomodulatory drug therapy (eg, thalidomide,
   interferon-alpha), Anagrelide, immunosuppressive therapy, corticosteroids >10 mg/day
   prednisone or equivalent, or growth factor treatment (eg, erythropoietin), or hormones
   (eg, androgens, danazol) within 14 days prior to initiation of IMP or placebo;
   darbepoetin use within 28 days prior to 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.

   - Major surgery within 28 days or radiation within 6 months 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])
