Primary Outcome Measures:
  • To evaluate safety and tolerability of NS-018 assessed by the type, frequency, seriousness and intensity of adverse events [ Time Frame: Throughout the study until 30 days after the last dose of study drug (patients with disease progression or no clinical benefit after 6 cycles [168 days] will be discontinued from the study) ] [ Designated as safety issue: Yes ]
    Phase 1 and Phase 2

  • To establish maximum tolerated dose of NS-018 [ Time Frame: Cycle 1 (28 days) ] [ Designated as safety issue: Yes ]
    Phase 1

  • To evaluate response to NS-018 treatment using the International Working Group-Myeloproliferative Neoplasms Research and treatment (IWG-MRT) and European LeukemiaNet (ELN) consensus, change in spleen size and bone marrow assessment [ Time Frame: Day 29, 57, 85, and every 84 days thereafter ] [ Designated as safety issue: No ]
    Phase 2

Secondary Outcome Measures:
  • To determine the pharmacokinetic parameters of NS-018 (Cmax, Tmax, AUC, t1/2 and accumulation ratio) [ Time Frame: Up to 24 hours post-dose on Day 1, 8, 15, 29 ] [ Designated as safety issue: No ]
    Phase 1 and Phase 2

  • To evaluate pharmacodynamic correlates of NS-018 [ Time Frame: Day 1, 8, 15, 29, 57, 85, and every 84 days thereafter ] [ Designated as safety issue: No ]
    Phase 1 and Phase 2

  • To evaluate quality of life assessments using Myelofibrosis Symptom Assessment Form (MF-SAF) for Phase 1 and the Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) for Phase 2. [ Time Frame: Day 29, 85, and every 84 days thereafter ] [ Designated as safety issue: No ]
    Phase 1 and Phase 2

Arms Assigned Interventions
Experimental: Intervention: Drug: NS-018 Drug: NS-018
Treatment will be administered continuously as oral daily therapy in cycles of 4 weeks in duration (28 day treatment cycles).

Detailed Description:

This is a Phase 1/2 study that is currently enrolling JAK2 failures into the Phase 2 portion of the study.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Primary myelofibrosis, post-PV MF, or post-ET MF that requires therapy
  • MF patients must have received prior JAK2 inhibitor therapy, and been found to be intolerant, or refractory/relapsed from prior JAK2 inhibitor therapy, based on investigator assessment
  • ≥18 years old
  • ECOG Performance Status of ≤ 3
  • Estimated life expectancy of ≥12 weeks
  • Male or non-pregnant, non-lactating female patients
  • Serum creatinine of ≤1.5 × the upper limit of normal (ULN)OR estimated creatinine clearance (CrCl) ≥ 40 ml/min/1.73 m2
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤3 × the upper limit of normal (ULN) and total bilirubin ≤1.5 × ULN. If the total bilirubin is elevated between 1.5 x and 3 x ULN, patients with a direct bilirubin ≤ 1.5 X ULN are eligible during the Phase II portion.
  • Absolute neutrophil count (ANC) >1000/μL and Platelet count > 25,000/μL
  • QTcB ≤ 480 msec
  • No MF-directed treatment for at least 2 weeks prior to initiation of NS-018, including any use of corticosteroids for Myelofibrosis symptom or blood count management. Low dose corticosteroids ≤ 10 mg/day prednisone or equivalent is allowed for non-myelofibrosis purposes.

Exclusion Criteria:

  • Active, uncontrolled systemic infection
  • Patients with any unresolved toxicity greater than Grade 1 from previous anticancer therapy
  • Potentially curative therapy is available
  • Currently taking medication that is substantially metabolized by cytochrome P450 (CYP) 1A2 or CYP3A4 or taking medication known to be strong inhibitors or inducers of CYP3A4
  • Patients with a serious cardiac condition within the past 6 months
  • Pregnant or lactating
  • Radiation therapy for splenomegaly within 6 months prior to study entry
  • Splenectomy (Phase 2 portion of the study only)
  • Known HIV positive status
  • Known active hepatitis, a history of viral hepatitis B or hepatitis C
