Trial Outcomes & Findings for Phase II, Open Label, Single Arm Study of SAR302503 In Myelofibrosis Patients Previously Treated With Ruxolitinib (NCT NCT01523171)

NCT ID: NCT01523171

Last Updated: 2026-07-16

Results Overview

Spleen volume was measured by central imaging MRI (CT scan in participants with contraindications for MRI). Analysis was performed on Per Protocol (PP) population defined as all treated participants with a baseline and at least one post-baseline MRI/CT scan of spleen volume, and had no important protocol deviations that could impact on efficacy outcome. Last observation carried forward (LOCF) method was used to impute the missing data.

PRIMARY outcome

Timeframe: Baseline, End of Cycle 6

Population: All treated participants with a baseline and at least one post-baseline MRI/CT scan of spleen volume.

Spleen volume was measured by central imaging MRI (CT scan in participants with contraindications for MRI). Analysis was performed on Per Protocol (PP) population defined as all treated participants with a baseline and at least one post-baseline MRI/CT scan of spleen volume, and had no important protocol deviations that could impact on efficacy outcome. Last observation carried forward (LOCF) method was used to impute the missing data.

SECONDARY outcome

Timeframe: Baseline, End of Cycle 6

Population: All treated participants with baseline and at least 1 post-baseline evaluable assessment of total symptom score.

The key MF-associated symptoms were assessed using the modified Myelofibrosis Symptom Assessment Form (MFSAF) Diary: night sweats, pruritus, abdominal discomfort, early satiety, pain under ribs on left side, and bone or muscle pain. These were measured on a scale from 0 (absent) to 10 (worst imaginable). Then Total symptom score (range 0 to 60) was defined as the sum of the scores for each of the 6 symptoms of MFSAF. Higher score indicated greater severity of symptoms. Analysis was performed on MFSAF analysis population defined as all treated participants with baseline and at least 1 post-baseline evaluable assessment of total symptom score.
