About this study

Official title: 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

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).
Read more

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.
Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Response Rate (RR): Percentage of Participants Who Had a >=35% Reduction From Baseline in Volume of Spleen Size at The End Cycle 6

    Spleen volume was determined by magnetic resonance imaging (MRI) (or computed tomography scan in participants with contraindications for MRI) at baseline and at the end of cycle 6 with a confirmatory scan approximately 4 weeks after the end of Cycle 6. The MRI or CT imaging results reviewed in a blinded manner by an Independent Review Committee (IRC). Analysis was performed on intent-to-treat (ITT) population defined as all randomized participants who signed informed consent form (ICF).

    Measured: Baseline, Week 24

Secondary outcomes (2)
  1. Symptom Response Rate (SRR): Percentage of Participants With >=50% Reduction From Baseline in the Total Symptom Score at End of Cycle 6

    Total symptom score is the averaged value of the daily scores for each of 6 key Myelofibrosis (MF) associated Symptom items (night sweats, pruritus, abdominal discomfort, early satiety [filling up quickly when you eat], pain under ribs on left side, and bone or muscle pain), each item measured on a scale from 0 (absent) to 10 (worst imaginable). A higher score indicates worse symptoms. Analysis was performed on ITT population. Number of participants analysed= participants with available data at end of cycle 6.

    Measured: Baseline, Week 24

  2. Percentage of Participants Who Had >=25% Reduction From Baseline in Volume of Spleen Size at End of Cycle 6

    Spleen volume was determined by magnetic resonance imaging (MRI) (or computed tomography scan in subjects with contraindications for MRI) at baseline and at the end of cycle 6 with a confirmatory scan approximately 4 weeks after the end of Cycle 6. Analysis was performed on ITT population.

    Measured: Baseline, Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SAR302503 in people with Hematopoietic Neoplasm, run by Bristol-Myers Squibb at 101 sites in 25 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 11 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 101 sites in United Kingdom, United States, France, Russia, South Korea and 20 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Aug 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Response Rate (RR): Percentage of Participants Who Had a >=35% Reduction From Baseline in Volume of Spleen Size at The End Cycle 6 (time frame: Baseline, Week 24). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01437787, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2026.
