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

United States, Australia, Austria289 participantsStarted 2011-12

Plain-language 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.

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 placebo: * 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 o…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Response Rate (RR), defined as the proportion of patients who have a ≥35% reduction in volume of spleen size at the end of Cycle 6, and confirmed 4 weeks thereafter
