What was measured

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).

Analysis population: All randomized participants.

Groups in this outcome

Placebo

Placebo up to 6 cycles (1 cycle=28 days - median exposure= 24 weeks). At the end of cycle 6, participants were crossed-over to SAR302503 400 or 500 mg until disease progression or unacceptable toxicity.

SAR302503 400 mg

SAR302503 400 mg until disease progression and/or unacceptable toxicity (median exposure= 62.1 weeks).

SAR302503 500 mg

SAR302503 500 mg until disease progression and/or unacceptable toxicity (median exposure =59.7 weeks).
