Design outcomes

Primary

MeasureTime frameDescription
Transfusion Independence Response by Week 24From baseline to Week 24The percentage of subjects who became transfusion independent for ≥ 12 weeks at any time on study. A subject was considered transfusion independent on study if no RBC transfusion occurred in any 12-week period during the 24-week treatment period.

Secondary

MeasureTime frameDescription
Splenic Response Rate at Week 24Measured at Week 24The percentage of subjects who achieved a ≥ 35% reduction in spleen volume from baseline as measured by MRI at Week 24.
Response Rate in Total Symptom Score (TSS) at Week 24Measured at Week 24The percentage of subjects achieving a ≥ 50% reduction from baseline in TSS at Week 24, as measured by the modified Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPNSAF TSS) diary. Total symptom score was assessed using the modified MPN-SAF TSS Version 2, an 8-item questionnaire developed to assess symptom burden and quality of life in patients with MPN. The modified MPN-SAF TSS contained 8 questions, 7 of which were summed to generate the score (the included questions related to tiredness, early satiety, abdominal discomfort, night sweats, itching, bone pain, and pain under the ribs on the left side). Each question is scored on a scale of 0-10, where higher numbers indicate more severe symptoms. For this study, the TSS scale ranges from 0 to 70. The questionnaire was completed daily on an electronic diary device.

Primary

Transfusion Independence Response by Week 24

The percentage of subjects who became transfusion independent for ≥ 12 weeks at any time on study. A subject was considered transfusion independent on study if no RBC transfusion occurred in any 12-week period during the 24-week treatment period.

Time frame: From baseline to Week 24

Population: Assessed in the Safety Analysis Set, which includes all subjects who received ≥ 1 dose of momelotinib. Note that 6 subjects discontinued prior to Week 12 and could not be evaluated over the minimum period required for assessment of the endpoint (12 weeks).

Response Rate in Total Symptom Score (TSS) at Week 24

The percentage of subjects achieving a ≥ 50% reduction from baseline in TSS at Week 24, as measured by the modified Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPNSAF TSS) diary. Total symptom score was assessed using the modified MPN-SAF TSS Version 2, an 8-item questionnaire developed to assess symptom burden and quality of life in patients with MPN. The modified MPN-SAF TSS contained 8 questions, 7 of which were summed to generate the score (the included questions related to tiredness, early satiety, abdominal discomfort, night sweats, itching, bone pain, and pain under the ribs on the left side). Each question is scored on a scale of 0-10, where higher numbers indicate more severe symptoms. For this study, the TSS scale ranges from 0 to 70. The questionnaire was completed daily on an electronic diary device.

Time frame: Measured at Week 24

Population: There were 3 subjects with missing TSS at baseline who were excluded from the analysis. Note that of the 38 subjects evaluated, 17 were missing Week 24 TSS assessments.

Splenic Response Rate at Week 24

Time frame: Measured at Week 24

Population: Assessed in the Safety Analysis Set, which includes all subjects who received ≥ 1 dose of momelotinib. Note that spleen volume at Week 24 was not available for 15 subjects.

Transfusion Response Rate by Week 24

The percentage of subjects who became transfusion independent for ≥ 8 weeks, defined as no RBC transfusions for at least an 8-week period at any time on study.

Time frame: From baseline to Week 24

Population: Assessed in the Safety Analysis Set, which includes all subjects who received ≥ 1 dose of momelotinib. Note that 3 subjects discontinued prior to Week 8 and could not be evaluated over the minimum period required for assessment of the endpoint (8 weeks).
