Brief summary

Proportion of patients with spleen volume reduction (SVR) of ≥35% (SVR35) at Week 24 as measured by MRI or CT scan by Investigator assessment, Absolute mean change in TSS (Abs-TSS) from baseline to Week 24 as measured by the Myelofibrosis Symptom Assessment Form (MFSAF) v4.0a

Detailed description

Proportion of patients with SVR35 at Week 48 as measured by MRI or CT scan by Investigator assessment, Overall survival (OS) defined as the time interval from the date of randomization to the date of death due to any cause., PFS as defined in the statistical analysis plan (SAP), Proportion of patients with SVR35 at any time point in the study as measured by MRI or CT scan., Absolute mean change in TSS (Abs-TSS) from baseline to Week 48 as measured by the Myelofibrosis Symptom Assessment Form (MFSAF) v4.0a, Incidence and severity of TEAEs including treatment-related adverse events (TRAEs), SAEs., PK endpoints including but not limited to AUC, Cmax, and Tmax., Proportion of patients with at least a 1-grade decrease in bone marrow fibrosis at any point in the study., Progression-free survival (PFS)
