Korábbi kezelés

• Any prior treatment with more than two JAK inhibitors.
• Previous treatment with NS-018.
• Subjects actively receiving a concurrent investigational agent.
• Subjects with any unresolved AE greater than Grade 1 other than hematological AEs from previous anticancer therapy.
• Currently taking medication that is substantially metabolized by cytochrome P450 (CYP) 1A2 or CYP3A4 (see Appendix 5) or taking medication known to be strong inhibitors or inducers of CYP3A4 (see Appendix 5).
• Radiation therapy for splenomegaly within 6 months prior to study entry (screening).
• Subjects diagnosed with another malignancy within 2 years prior to an enrollment.
• Subjects who have had surgery (other than placement of vascular access and bone marrow biopsy) within 4 weeks of study entry (screening), or subjects with incomplete recovery from any prior surgical procedures.

• Primary MF, post-PVMF or post-ETMF according to the DIPSS risk categories of intermediate-2 or high-risk MF
• Average platelet count of <50,000/µL at Screening based on 2 measurements taken on different days; both measurements must be <50,000/µL.
• ECOG performance status ≤2.
• Life expectancy >6 months.
• Spleen volume of at least 450 cm3 measured by MRI (or by CT for applicable subjects).
