Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Part 1 and Part 2: Number of Subjects With Adverse Events and Serious Adverse Event
Time Frame: From screening to until study discontinuation (approximate 8 years 10 months)
|
AEs (non-serious, serious) as variables of safety and tolerability of NS-018 were assesed.
The number of patients were presented as Overall summary of AEs including treatment-emergent AEs (TEAEs); Treatment-emergent SAEs; Drug-related TEAEs; Treatment-emergent AEs leading to permanent discontinuation of study drug; Hospitalization or prolongation of existing hospitalization; Death.
|
From screening to until study discontinuation (approximate 8 years 10 months)
|
Part 2: Number of Patient With Objective Response Using International Working Group-Myeloproliferative Neoplasms Research and Treatment (IWG-MRT) and European Leukemia Net (ELN)
Time Frame: Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Six response categories are listed: complete remission (CR) and partial remission signify treatment effects that are consistent with disease modification, whereas drug-induced improvements in MF-symptomatic burden were annotated as clinical improvement, anemia response, spleen response, orsymptoms response.
Additional criteria are provided for progressive disease, stable disease, and relapse.
The objective response was defined as the number of patients with confirmed complete remission (CR) + partial response (PR) + clinical improvement (CI) during the treatment period.
|
Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Part 2: Change From Baseline in Spleen Size
Time Frame: From Baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Change from baseline in spleen size was assessed by magnetic resonance imaging (MRI) (computed tomography [CT] scan for patients not able to tolerate MRI).
|
From Baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Part 2: Change From Baseline in Bone Marrow Assessment
Time Frame: From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Bone marrow was assessed by aspiration and biopsy for grade changes in osteomyelofibrosis.
Fibrosis was graded according to European Consensus Myelofibrosis Grading Criteria, ranging from grade 0, which corresponds to normal bone marrow, to grade 3, in which coarse bundles of collagen fibrosis are identifiable with significant osteosclerosis.

Part 1: Change From Baseline in Bone Marrow Assessment
Time Frame: From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Bone marrow was assessed by aspiration and biopsy for grade changes in osteomyelofibrosis.
Fibrosis was graded according to European Consensus Myelofibrosis Grading Criteria, ranging from grade 0, which corresponds to normal bone marrow, to grade 3, in which coarse bundles of collagen fibrosis are identifiable with significant osteosclerosis.

|
Part 1: Change From Baseline in Quality of Life Assessments Using Myelofibrosis Symptom Assessment Form (MF-SAF)
Time Frame: From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
MF SAF is a 20-item instrument comprised of 4 subscales: 1) the Brief Fatigue Inventory [= average of 9 fatigue scores], 2) Splenomegaly associated symptoms [= average of 4 splenomegaly and associated scores], 3) Catabolic/proliferative Symptoms [= average of 3 catabolic/proliferative associated scores] and 4) Overall Quality of Life.
The items were on a scale from 1 to 10 where 1= most favorable, and 10= least favorable.
|
From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Part 2: Change From Baseline in Quality of Life Assessments Using Myeloproliferative Neoplasm Symptom Assessment Form (MPN SAF (MPN 10)
Time Frame: From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Symptoms are evaluated by the MPN-SAF Total Symptom Score (TSS).
The MPN-SAF TSS is assessed by the patients themselves and this includes fatigue, concentration, early satiety, inactivity, night sweats, itching, bone pain, abdominal discomfort, weight loss, and fevers.
Scoring is from 0 (absent/as good as it can be) to 10 (worst imaginable/as bad as it can be) for each item.
The MPN-SAF TSS is the summation of all the individual scores (0-100 scale).
Symptoms response requires >50% reduction in the MPN-SAF TSS.

From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Part 1 and Part 2: Change in Baseline in Janus Kinase 2 (JAK2) V617F Allele Burden Levels
Time Frame: Part 1 and Part 2: From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
The JAK2 V617F allele burden mean changes from baseline (%) are presented as pharmacodynamics parameters.
|
Part 1 and Part 2: From baseline to Cycle 7 Day 1 (duration of cycle was 4 weeks)
|
Part 2: Change From Baseline in Phosphorylated Signal Transducer and Activator of Transcription 3 (Phospho-STAT3)
Time Frame: From Baseline to Pre-dose at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 (duration of cycle was 4 weeks)
|
The Phospho-STAT3 mean changes from baseline (%) are presented as pharmacodynamics parameters. For phospho-STAT3 values (Phase 2 only), study samples were incubated (± IL-6) and labeled with CD markers. Surface markers included CD3+ (CD4+ [helper T cells] and CD8+ [cytotoxic T cells]) and CD14+ (monocytes) to which intracellular phospho STAT3 was targeted. The levels of phospho-STAT3 in CD14+, CD3+CD4+ and CD3+CD8+ cell subtypes were quantified. Phosphorylated-STAT3 levels were evaluated in the cell types before and after IL-6 incubation (stimulation) and reported both as mean fluorescence intensity (MFI) and the percentage of positive cells. For each sample time point, the MFI was normalized to a fold change. The fold change was calculated by MFI after IL-6 treatment/MFI before IL-6 treatment. The percent positive cells were normalized by subtracting the percent positive cells before IL-6 treatment from the percent positive cells after IL-6 treatment. |
