Primary Outcome Measures
NameTimeMethod
Main Objective: Evaluate the effect of navitoclax alone or in combination with ruxolitinib on spleen volume;Secondary Objective: - To assess the effect of navitoclax alone or in combination with ruxolitinib on total symptom score (TSS) as assessed by the Myelofibrosis Symptom Assessment Form (MFSAF) version 4.0 diary<br>- To evaluate the effect of navitoclax alone or in combination with ruxolitinib on bone marrow fibrosis<br>- To determine the overall response rate (ORR = sum of rates of complete remission [CR] + partial remission [PR]) associated with navitoclax alone or in combination with ruxolitinib<br>- To determine the rate of anemia response associated with navitoclax alone or in combination with ruxolitinib<br>- To describe the safety profile and PK profile observed with navitoclax alone or in combination with ruxolitinib<br>;Primary end point(s): = 35% spleen volume reduction from baseline (SVR35) at Week 24<br>measured by MRI/CT.;Timepoint(s) of evaluation of this end point: Week 24
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): The secondary endpoints are at least 50% reduction in total symptom<br>score from baseline measured by MFSAF 4.0; anemia response; and<br>change in grade of bone marrow fibrosis.;Timepoint(s) of evaluation of this end point: Week 24
