Overall Rationale for the Global Amendment: 
The purpose of this global amendment from Protocol Version 2.0 is to harmonize the protocol 
language related to contraception per Clinical Trials Facilitation Group (CTFG) guidance and is 
aligned to harmonize with the European union (EU) submissions.  Changes that apply to all 
countries are harmonized throughout this amendment where applicable.  This global protocol 
amendment consolidates country-specific protocol changes requested by each country’s 
competent authority.   
The changes from Protocol Version 2.0 to this amendment are provided in the following table.

Changes that are country-specific for Germany, Italy, and UK are identified, respectively, in the 
following sections. 
Germany Protocol V1.2 
Germany protocol version 1.2, dated 25 August 2022, was amended based on the criteria set 
forth in Article 10(a) of Directive 2001/20/EC of the European Parliament and the Council of the 
European Union in a letter dated 19 May 2022, because it significantly impacts the safety or 
physical/mental integrity of subjects or the scientific value of the study, given the phase of this 
study, study population and expected menopausal status/use of contraception for the enrolled 
subjects.  
Overall Rationale for the Germany Amendment: 
The following table is the summary of changes requested and approved by the Germany Federal 
Institute for Drugs and Medical Devices in a letter dated 16 January 2023 and consolidated in 
this global amendment.

Section # and Name 
Description of Change 
Brief Rationale 
Section 8.2, Safety 
Assessments 
Appendix 17 Schedule of 
Assessment for Germany 
Only  
Added text under “Safety 
Assessments” to specify to closely 
monitor safety of BAT patients 
transitioning to NS-018. 
Text was updated, as NS-018 has very 
limited clinical data to date, and an 
adjustment of the test plan to closely 
monitor safety of BAT subjects 
transitioning to NS-018 was required.  
This change was not included in amendment 
version 1.1 as initially requested by the 
Germany Federal Institute for Drugs and 
Medical Devices in a letter dated 
10 Feb 2022 and is now included in this 
amendment version 1.2. 
Section 5.1, Inclusion 
Criteria 16 
Revised text. 
Text was revised to delete any specific 
information and to refer to protocol 
Appendix 7, to avoid conflicting 
information defined in Appendix 6 and to 
clarify the contraception requirements.  
Text referring to complete abstinence, 
double-barrier method, tubal ligation or 
vasectomy were removed. 
Section 11.0, Appendix 6 
(Contraceptive Guidance 
and Collection of 
Pregnancy Information) 
Revised text under “Male subjects” 
to clarify sperm donation and the 
use of condom. 
Text was revised to clarify that male 
subjects must refrain from donating sperm 
for the duration of the study and for 
180 days after study completion or the last 
dose of study treatment. 
Text was revised to clarify that male 
subjects with partners who are WOCBP, 
pregnant or breastfeeding must agree to 
remain abstinent from penile vaginal 
intercourse throughout the study treatment 
period until 180 days from last study 
treatment. 
The use of condom was also removed from 
the text given that it is not “highly effective” 
as per the CTFG contraception guidance – 
subsection 4.2. 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
18 
Section # and Name 
Description of Change 
Brief Rationale 
 
Revised text under “Female 
subjects” to clarify contraceptive 
use. 
Text was revised for female subjects that 
they must use 2 highly effective 
contraceptive methods during the study and 
for 180 days after last dose of NS-018 as per 
Appendix 6 guidance for males, or for the 
duration required by product information of 
the comparator drug. 
 
Added text under “Female subjects” 
to follow the contraception 
requirements of comparator 
therapies. 
Added text to state that contraception 
requirements of comparator therapies must 
be followed.  As these comparator therapies 
are started in this protocol, this advice must 
be included in the protocol. 
 
Removed footnote b from table for 
“Highly Effective Contraceptive 
Methods” and replaced with revised 
text. 
Removed “hormonal contraception 
methods” clarifying that they cannot 
be used. 
Text was revised to state that hormonal 
contraception methods are not allowed to be 
used.  The IB indicates that NS-018 may be 
susceptible to drug-drug interactions and no 
results of clinical drug-drug interaction 
studies are provided.  Therefore, hormonal 
contraception will not be allowed, and this 
option was removed from the protocol. 
 
Added the following text under 
“Pregnancy Testing”: 
“Monthly pregnancy tests should be 
performed for WOCBP.  The serum 
pregnancy test should not be older 
than 72 hours before taking the first 
dose of study treatment.”. 
Text was revised based on incomplete 
preclinical toxicity testing program and 
related toxicity as described in the IB. 
Throughout 
Text edits. 
Minor editorial changes were made for 
consistency.

Section # and Name 
Description of Change 
Brief Rationale 
Throughout 
Updated with edits, such as 
replacing abbreviations with spelled 
out words and corrections of 
misspelled words, that were made 
in various sections throughout the 
protocol.  
For added clarity and per standard 
style guide. 
Section 1.1 Synopsis 
Section 4.1 Overall Design 
The following sentences were 
removed. 
Subjects treated with a JAK 
inhibitor will be required to taper of 
this treatment before initiation of 
NS 018 at Cycle 1 Day 1.  The dose 
of JAK inhibitor should be 
decreased every 7 days by up to 
50% until the smallest dose 
possible has been given for a 
minimum duration for the total 
tapering period of 14 days.  JAK 
inhibitor should then be stopped 1 
day before starting NS-018.  
Subjects who are taking 5 mg QD 
of a JAK inhibitor are already on 
the lowest dose possible; therefore, 
tapering is not applicable in this 
case.  If recurrence of MF-related 
symptoms (upon discontinuation of 
a JAK inhibitor therapy) is noted, it 
is strongly suggested that therapy 
with a JAK inhibitor be restarted.  
If restart is not possible, then 
prompt therapy with corticosteroids 
(eg, prednisone 60 mg QD) is 
recommended. 
To be consistent with inclusion 
criteria #7 that was changed as 
requested by the Italian Medicines 
Agency.   
Section 2.2 Background 
Replaced “30 da” with “survival” 
after “shortened” 
Typographical error correction.

Section # and Name 
Description of Change 
Brief Rationale 
Section 5.1 Inclusion Criteria 
The following inclusion criteria #7 
was removed as it is only applicable 
for Italy.  
“Subjects treated with a JAK 
inhibitor will be required to taper of 
the JAK inhibitor before initiation 
of NS-018 at Cycle 1 Day 1.  The 
dose of JAK inhibitor should be 
decreased every 7 days by up to 
50% until the smallest dose 
possible has been given for a 
minimum duration for the total 
tapering period of 14 days.  JAK 
inhibitor should then be stopped 
1 day before starting NS-
018.  Subjects who are taking 5 mg 
QD of a JAK inhibitor are already 
on the lowest dose possible; 
therefore, tapering is not applicable 
in this case.  If recurrence of MF-
related symptoms (upon 
discontinuation of a JAK inhibitor 
therapy) is noted, it is strongly 
suggested that therapy with a JAK 
inhibitor be restarted.  If restart is 
not possible, then prompt therapy 
with corticosteroids (eg, prednisone 
60 mg QD) is recommended.”  
The following sentence was added.  
“Subjects who are not benefitting 
from ruxolitinib treatment may be 
enrolled in the study per the 
Investigator’s discretion.” 
Inclusion criteria #7 was changed 
as requested by the Italian 
Medicines Agency. 
Section 5.2 Exclusion Criteria 
The following criteria was added. 
3. Subjects receiving any clinical 
benefits from JAK inhibitor per the 
Investigator’s discretion. 
Exclusion criteria 3. was added to 
reinforce the change in inclusion 
criteria #7 as requested by the 
Italian Medicines Agency.

United Kingdom Protocol Version 1.2 
Overall Rationale for the United Kingdom Amendment: 
United Kingdom (UK) protocol version 1.2, dated 19 July 2022, was amended to incorporate the 
changes requested by the UK Medicines and Healthcare products Regulatory Agency 
(MHRA) in a letter dated 26 May 2022.  
The following table is a summary of changes requested and approved by the MHRA in a letter 
dated 02 November 2022 and consolidated in this global amendment.

Section # and Name 
Description of Change 
Brief Rationale 
Section 5.1, Inclusion 
Criteria 16 
Revised text. 
Text was revised to delete any specific 
information and to refer to protocol 
Appendix 7, to avoid conflicting 
information defined in Appendix 6 and to 
clarify the contraception requirements.  
Text referring to complete abstinence, 
double-barrier method, tubal ligation or 
vasectomy were removed. 
Section 11.0, Appendix 6 
(Contraceptive Guidance 
and Collection of 
Pregnancy Information) 
Revised text under “Male subjects” 
to clarify sperm donation and the 
use of condom. 
Text was revised to clarify that male 
subjects must refrain from donating sperm 
for the duration of the study and for 
180 days after study completion or the last 
dose of study treatment. 
Text was revised to clarify that male 
subjects with partners who are WOCBP, 
pregnant or breastfeeding must agree to 
remain abstinent from penile vaginal 
intercourse throughout the study treatment 
period until 180 days from last study 
treatment. 
The use of condom was also removed from 
the text given that it is not “highly effective” 
as per the Clinical Trial Facilitation Group 
contraception guidance – subsection 4.2. 
 
Revised text under “Female 
subjects” to clarify contraceptive 
use. 
Text was revised for female subjects that 
they must use 2 highly effective 
contraceptive methods during the study and 
for 180 days after last dose of ilginatinib as 
per Appendix 6 guidance for males, or for 
the duration required by product 
information of the comparator drug. 
 
Added text under “Female subjects” 
to follow the contraception 
requirements of comparator 
therapies. 
Added text to state that contraception 
requirements of comparator therapies must 
be followed.  As these comparator therapies 
are started in this protocol, this advice must 
be included in the protocol.

Section # and Name 
Description of Change 
Brief Rationale 
 
Removed footnote b from table for 
“Highly Effective Contraceptive 
Methods” and replaced with revised 
text. 
Removed “hormonal contraception 
methods” clarifying that they cannot 
be used. 
The text in footnote b was unclear and also 
made the unclarified recommendation to use 
2 highly effective methods, which could 
mean 2 types of hormonal methods, or 
1 type of hormonal method combined to 
another highly effective method.  
Text was revised to state that hormonal 
contraception methods are not allowed to be 
used.  The IB indicates that ilginatinib may 
be susceptible to drug-drug interactions and 
no results of clinical drug-drug interaction 
studies are provided.  Therefore, hormonal 
contraception will not be allowed, and this 
option was removed from the protocol. 
Throughout 
Text edits. 
Minor editorial changes were made for 
consistency

1.0 PROTOCOL SUMMARY 
1.1 
Synopsis 
Protocol Title: A Phase 2b, Open-label, Multicenter, Randomized, Controlled, 2-Arm Study to Assess 
the Efficacy and Safety of Orally Administered NS-018 versus Best Available Therapy in Subjects with 
Primary Myelofibrosis, Post-Polycythemia Vera Myelofibrosis, or Post-Essential Thrombocythemia 
Myelofibrosis with Severe Thrombocytopenia (Platelet Count <50,000/μL) 
Study Rationale:  
NS-018 is a potent and specific Janus kinase 2 (JAK2) inhibitor which was designed and synthesized by 
Nippon Shinyaku Co., Ltd.  NS-018 is being developed as a therapeutic agent for myeloproliferative 
neoplasm (MPN) including myelofibrosis (MF).  A Phase 1/Phase 2, multicenter, dose-escalation, open-
label study of NS-018 was conducted in subjects with primary myelofibrosis (PMF), post-polycythemia 
vera MF (PVMF), or post-essential thrombocythemia MF (ETMF) with 10 dosing cohorts (Study No. 
NS-018-101 [NCT01423851]).  A total of 48 evaluable subjects were enrolled in the Phase 1 part of the 
study.  The best response in palpable spleen size reduction of ≥50% observed was similar between 
subjects administered with 300 mg once daily (QD) and twice daily (BID), which is 56% (5/9) and 50% 
(3/6), respectively.  In terms of safety, both 300 mg QD and 300 mg BID were tolerable.  The safety data 
showed a difference between 300 mg QD (17%, 1/6) and 300 mg BID (50%, 4/8) in dose reduction or 
discontinuation up to Cycle 7 Day 1 (first dose cohort).  The 300 mg QD dose was selected as the dose 
for the Phase 2 part of Study NS-018-101.  A total of 29 evaluable subjects were enrolled in the Phase 2 
part of Study NS-018-101.  In the Phase 2 part of the study, spleen volume reduction (SVR) was 
measured by magnetic resonance imaging (MRI) or computed tomography (CT) scan.  There were no 
safety concerns in subjects administered with 300 mg QD; however, only 1 subject with a baseline 
platelet count of <50,000/μL achieved ≥35% reduction in spleen size volume as measured by MRI at 
Cycle 7.  There was a trend, however, that subjects with higher area under the plasma concentration-time 
curve (AUC) obtained higher efficacy in terms of SVR and an improvement of symptoms.  In the Phase 1 
part of Study NS-018-101, there was no clear difference in drug-related hematological adverse events 
(AEs) between 300 mg QD and 300 mg BID (Grade 3/4 thrombocytopenia: 13% (2/15) and 8% (1/12), 
Grade 3/4 anemia: 0% and 17% (2/12), respectively.  The safety assessment of 300 mg QD showed no 
clear difference from 300 mg BID in terms of drug-related non-hematological AEs (gastrointestinal 
disorders 4/15 [27%] versus 6/12 [50%]; nervous system disorders 6/15 [40%] versus 5/12 [42%]), with 
dizziness and nausea the most common toxicities in these classes, respectively.   
In reviewing the available data, the following 3 factors were considered in the selection of subjects with 
severe thrombocytopenia (platelet count <50,000/μL) and the 300 mg BID dose that will be used in the 
NS-018-201 study: 1) 300 mg BID safety profile that was demonstrated in the Phase 1 part of Study 
NS-018-101 (n=12); 2) demonstrated efficacy of >35% SVR as measured by MRI at Cycle 7 in 1 subject 
with baseline platelet count of <50,000/μL who received 300 mg QD in the Phase 2 part of 
Study NS-018-101; and 3) detected trend in higher efficacy in SVR and improvement in symptoms in 
those subjects with higher AUC.

care/therapy’.  The BAT should be administered according to the manufacturer’s instructions or the 
Investigator’s discretion.  The BAT is ‘supportive care/therapy’, and refers to use of blood products, 
fluids (crystalloids), pain medications, and/or antibiotics, that subjects will need to manage myelofibrosis 
symptoms and complications.  Subjects in the control group will receive BAT at doses and schedules 
selected by the Investigator based on the subject’s condition and according to the manufacturer’s 
instructions or the Investigator’s discretion.  The BAT must be a single agent and cannot be combined 
with other agents.  JAK inhibitor can be allowed as BAT if the JAK inhibitor was administered as a 
standard of care based on the product label or Investigator’s discretion.  The BAT may be changed at any 
time during the randomized treatment period based on the Investigator’s clinical assessment of the 
subject’s condition.  However, it is not allowed to change the BAT to JAK inhibitor if it was not used as 
standard of care treatment prior to study participation. .  No experimental agents (ie, those not approved 
for any indication) may be used at any time.  
Study Visits 
Subjects will have regular scheduled study visits at screening, Day 1, Day 15 of Cycles 1, 2, 3, 4, 5, and 
6, and Day 1 of every cycle thereafter.  One cycle is 28 days.  Subjects transitioning from BAT to NS-018 
before or at Cycle 7 Day 1 will have safety laboratory assessments performed on Day 1 and Day 15 of 
each cycle for 6 cycles.  Safety laboratory assessments will continue on Day 1 of the following cycles 
until the end of the study and will be done by a central laboratory (refer to Appendix 17 SoA for further 
details).  Additional local laboratory assessments may be performed per Investigator’s discretion to 
monitor safety and document AEs as per local standards of care.    
Subjects in South Korea only, safety laboratory assessments will be performed weekly at Cycle 1 on 
Day 1, Day 8, Day 15, and Day 22, and Cycles 2 through 6 will be performed on Days 1 and 15, and Day 
1 of each cycle thereafter.  Laboratory visits on Day 8 and Day 22 of Cycle 1 for subjects randomized to 
NS-018 or Cycle 1 after transitioning to NS-018 in subjects who transition to NS-018 will be performed 
at the institutional local laboratory (refer to Appendix 15 SoA for further details).   
Subjects who transition from BAT to NS-018 will have a physical examination done on Day 1 of each 
cycle for the first 4 cycles after transitioning to NS-018 and on Day 1 of every three cycles thereafter, as 
subjects are transitioned to NS-018.  Vital signs will be done on Day 1 of each cycle after transitioning to 
NS-018.  Vital signs will be taken within 3 hours before transitioning to NS-018.  Electrocardiogram 
(ECG) will be done on Day 1 and Day 15 of the first cycle and on Day 1 of the second and fourth cycles 
after transitioning to NS-018, and on Day 1 of every 3 cycles thereafter as subjects randomized to 
NS-018.  Each ECG measurement will be performed 2 hours (±10 minutes) postdose.   
Subjects treated with ruxolitinib will be required to taper off this treatment before initiation of NS-018 at 
Cycle 1 Day 1.  The dose of ruxolitinib should be decreased every 7 days by up to 50% until the smallest 
dose possible has been given for a minimum duration of total tapering period of 14 days.  Ruxolitinib 
should then be stopped 1 day before starting NS-018.  Subjects who are taking 5 mg QD of ruxolitinib as 
standard of care prior to study participation, are already on the lowest dose possible; therefore, tapering is 
not applicable in this case.  If recurrence of MF-related symptoms upon discontinuation of ruxolitinib 
therapy is noted, it is strongly suggested that therapy with ruxolitinib be restarted.  If restart is not 
possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg QD) is recommended.

Eligible subjects will receive NS-018 or BAT according to treatment assignment from Cycles 1 to 6 until 
one of the following criteria for disease progression is met: 
1. Increase in spleen volume of ≥15% measured by MRI (or by CT for applicable subjects) from the 
baseline for subjects who are randomized to NS-018 or transitioned to NS-018. 
2. Splenic irradiation or splenectomy. 
3. Leukemic transformation defined by an increase in peripheral blood blast percentage to ≥20% 
that is sustained for at least 8 weeks. 
4. Leukemic transformation defined by bone marrow blast count of ≥20%. 
5. Death. 
Subjects who meet the criteria for increase in spleen volume of >15% measured by MRI (or by CT for 
applicable subjects), leukemic transformation, or have had splenic irradiation will be discontinued from 
the study treatment and will be asked to complete the end of study procedures.  Subjects randomized to 
the BAT arm (ie, subjects already on BAT or ‘supportive care/therapy’ and met all of the following 
criteria may transition to NS-018 treatment.   
 
Subject has completed at least 24 weeks on BAT or had progression of disease prior to Week 24; 
progression must be declared based only on an increase in splenic volume of >15% measured by 
MRI (or by CT for applicable subjects) from baseline. 
 
Subject has not undergone splenic irradiation or splenectomy. 
 
Subject does not meet criteria for leukemic transformation. 
There will be no MF-directed treatment (other than ruxolitinib) for at least 1 week (7 days) prior to 
initiation of NS-018 after completion of BAT.  Changes in the MF-directed treatment should be 
documented.  
Subjects randomized to receive either NS-018 or BAT may continue to receive NS-018 after completion 
of Cycle 6.  In the BAT treatment arm (control group), after subjects have completed treatment with BAT 
at the end of Cycle 6, the Investigator will determine whether subjects should continue BAT treatment 
outside the study (ie, withdrawn from the study) or discontinue BAT and transition to NS-018 at Cycle 7 
Day 1.  During this transition period, subjects treated with ruxolitinib will be required to taper off this 
treatment before initiation of NS-018.  The dose of ruxolitinib should be decreased every 7 days by up to 
50% until the smallest dose possible has been given for a minimum duration for the total tapering period 
of 14 days.  Ruxolitinib should then be stopped 1 day before starting NS-018.  Subjects who are taking 
5 mg QD of ruxolitinib are already on the lowest dose possible; therefore, tapering is not applicable in 
this case.  If recurrence of MF-related symptoms (upon discontinuation of ruxolitinib therapy) is noted, it 
is strongly suggested that therapy with ruxolitinib be restarted.  If restart is not possible, then prompt 
therapy with corticosteroids (eg, prednisone 60 mg QD) is recommended.   
Subjects receiving treatment other than ruxolitinib will undergo a minimum washout period of 1 week (7 
days) prior to start of NS-018 treatment. 
For subjects receiving BAT and transitioning to NS-018 before Cycle 7 Day 1, subjects will be required 
to taper off or washout this treatment before initiation of NS-018 as described above.

Subjects may continue to receive treatment with NS-018 until the subject meets the discontinuation 
criteria of study treatment (see Section 7.1 of protocol), or until 3 years (expected) after the first subject is 
enrolled at any of the study centers, whichever comes first.  Dose modification is allowed for subjects 
who experience Grade 4 neutropenia, lymphopenia or bleeding, or Grade 3 or 4 non-hematologic AEs 
(see Section 6.6 of protocol).   
Visits for subjects in South Korea, UK, and Germany are detailed in a separate schedule of assessments 
(SoA) in Appendix 15, Appendix 16, and Appendix 17, respectively. 
Number of Investigators and Study Centers: 
A total of 65 Investigators and study centers in multiple countries are expected to participate in this study.  
Additional study centers may be added to support enrollment. 
Number of Subjects: 
A total of 120 subjects are expected to be enrolled and randomized 1:1 to either of the following treatment 
arms:  
 
NS-018 
 
BAT 
See Section 9.2 of the protocol. 
Treatment Groups and Duration: 
Individual subject participation will depend upon the ability to tolerate the treatment regimen and upon 
the time to a progression event mandating study withdrawal. 
The screening period is 28 days before start of treatment.  During screening, all subjects will be evaluated 
for active tuberculosis.  Additionally, inactive (latent) tuberculosis testing will be done in UK and South 
Korea by local laboratory for all subjects.  At Cycle 1 Day 1, before the subject starts study treatment, all 
eligibility criteria including the subject’s status for coronavirus disease 2019 (COVID-19) must be 
reviewed and confirmed.  All subjects will be treated from Cycle 1 Day 1 through the end of the study.  
There will be an indefinite period from Cycle 7 Day 1 until the subject meets the criteria of 
discontinuation of study treatment (see Section 7.1 of protocol), or until 3 years (expected) after the first 
subject is enrolled at any of the study centers, whichever comes first.  All subjects will have a follow-up 
visit within 30 days after study completion or early termination.  
Statistical Methods: 
Sample size: 
A total of 120 randomized subjects (60 subjects in each treatment arm) is planned.  The sample size 
determination is based on literature. 
Assuming a splenic response rate of 20% in the NS-018 arm and 1% in the BAT arm, there is 93.5% 
power at the final analysis to maintain a type I error rate of 5% (ie, a 2-sided significance level using 
Fisher’s exact test is 5%).  Similarly, assuming a symptom response rate of 33% in the NS-018 arm and 
8% in the BAT arm, the power of the final analysis to maintain a type I error rate of 5% is 91.0%.  
Assuming that there is no correlation between SVR and total symptom score (TSS) reduction, the power 
to reject the null hypothesis for both endpoints is 85.1%.

Analysis Populations:  
The intent-to-treat (ITT) population will consist of all randomized subjects. 
The modified intent-to-treat (mITT) population will consist of all randomized subjects who receive at 
least 1 dose of study treatment and have a baseline assessment and at least 1 postbaseline efficacy 
assessment.  Subjects will be analyzed as randomized.  This will be the primary analysis population for 
the evaluation of efficacy. 
The safety (SAF) population will consist of all randomized subjects who receive at least 1 dose of study 
treatment.  For BAT subjects who do not receive therapy, a Cycle 1 Day 1 visit is required to be included 
in the SAF.  Subjects will be analyzed as treated.  This will be the primary analysis population for the 
evaluation of exposure and safety. 
A second safety (SAF2) population will consist of subjects randomized to BAT who complete BAT 
through 6 cycles and go on to receive at least 1 dose of NS-018.  Baseline will consist of the last data 
available prior to initiation of NS-018.  
The PK concentration population will consist of all randomized subjects who receive at least 1 dose of 
study treatment and have at least 1 plasma concentration value for study treatment. 
General Statistical Considerations:  
All statistical tests will be performed at a significance level of 0.05 with no corrections for multiple 
comparisons. 
The first primary endpoint of a proportion of subjects who achieve ≥35% SVR from baseline to Week 24 
will be compared between the NS-018 group and the BAT group using Firth-corrected logistic regression 
model.  Covariates of baseline spleen volume and a history of prior JAK inhibitor treatment will be 
included.  Model-based point estimates for the treatment effects, 95% confidence intervals, and p-values 
will be calculated.  Subjects who do not reach Week 24 will be considered treatment nonresponders 
(ie, did not achieve ≥35% SVR from baseline to Week 24).  No imputations will be made for missing 
data. 
Similar to the analysis of the first primary endpoint, the second primary endpoint of proportion of subjects 
who achieve ≥50% reduction in TSS from baseline to Week 24 as measured by MF-SAF v4.0 and the 
secondary endpoint of proportion of subjects who achieve ≥35% SVR any time up to Week 24 will be 
compared between the NS-018 group and the BAT group using Firth-corrected logistic regression model.  
Covariates of baseline spleen volume and a history of prior JAK inhibitor treatment will be included. 
Adverse events will be coded using the Medical Dictionary for Regulatory Activities.  For each study 
treatment, numbers of treatment-emergent AEs (TEAEs) and incidence rates will be tabulated by 
preferred term and system organ class.  
Treatment-emergent AEs by maximum severity, TEAEs by relationship to study treatment, serious 
adverse events (SAEs), TEAEs leading to death, and TEAEs leading to discontinuation of study treatment 
will be tabulated for each treatment group.  
All central and local laboratory test results, vital signs measurements, electrocardiogram results, physical 
examination, spleen size (by palpation), spleen volume (by MRI) and weight will be summarized for each 
treatment group using descriptive statistics at each visit for raw numbers and change from baseline.

No interim analysis is planned for efficacy.  The primary efficacy analyses will be conducted after all 
subjects have completed assessments at Week 24 (Cycle 7 Day 1).  A final analysis will be conducted at 
the end of the study.  An additional analysis for futility may also be performed.  The statistical analysis 
plan will describe these analyses in greater detail. 
Independent Data Monitoring Committee (IDMC):  
An IDMC will be set up to oversee safety across the life span of the study and all specifics will be 
captured in the IDMC charter.

a Subjects in the control group may receive BAT at doses and schedules selected by the Investigator discretion and 
based on subject’s condition. 
b In the BAT treatment arm (control group), after subjects have completed treatment with BAT including BAT 
‘supportive care/therapy’, at the end of Cycle 6, the Investigator will determine whether subjects should continue 
BAT treatment outside the study or discontinue BAT and transition to NS-018 at Cycle 7 Day 1.  During this 
transition period, subjects must not receive any MF-directed treatment (other than ruxolitinib) for a minimum 
period of 1 week (7 days) prior to start of NS-018 treatment. 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0

c Subjects treated with ruxolitinib will be required to taper off ruxolitinib before initiation of NS-018.  The dose of 
ruxolitinib should be decreased every 7 days by up to 50% until the smallest dose possible has been given for a 
minimum duration for the total tapering period of 14 days.  Ruxolitinib should then be stopped 1 day before 
starting NS-018.  Subjects who are taking 5 mg once daily (QD) of ruxolitnib, are already on the lowest dose 
possible; therefore, tapering is not applicable in this case.  If recurrence of MF-related symptoms (upon 
discontinuation of ruxolitinib therapy) is noted, it is strongly suggested that therapy with ruxolitinib be restarted. 
If restart is not possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg QD) is recommended. 
d Within 14 days after last dose of study treatment or within 14 days after withdrawal from the study. 
e The planned end of study is the scheduled date when the final subject enrolled completes the 30-day follow-up 
phone call after completion of the end of study procedures. 
f 
Indefinite period from Cycle 7 Day 1 until the subject experiences unacceptable toxicity that precludes any 
further treatment, disease progression, and/or loss of benefit from treatment, at the discretion of the Investigator, 
or until 3 years after the first subject in, whichever comes first.

Subjects transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have safety laboratory assessments performed on Day 1 and 15 of each cycle for 6 cycles.  Safety 
laboratory assessments will continue on Day 1 of the following cycles until the end of the study and will be done by a central laboratory.  Hematology includes erythrocytes, 
MCV, MCH, neutrophils, eosinophils, basophils, lymphocytes, monocytes, platelets, leukocytes, hemoglobin, and hematocrit.  Serum chemistry includes BUN, LDH, 
creatinine, uric acid, total protein, albumin, glucose, direct bilirubin for screening, total bilirubin (for safety assessment), magnesium, ALP, AST, ALT, chloride, sodium, 
potassium, amylase, and lipase.  Urinalysis includes pH, protein, glucose, ketone, bilirubin, blood, and nitrite. Note: Additional local laboratory assessments may be performed 
per Investigator’s discretion to monitor safety and document AEs as per local standards of care. 
g 
For eligibility determination and centrally read for all subjects; median QTcF must be ≤480 msec.  For screening, Cycles 1 and 2, triplicate central reading, and then from Cycle 
4 onwards, single central reading.  ECG is required at screening for all subjects but only for NS-018 subjects at the remaining study visits.  ECGs for Cycle 1 Day 1: Predose 
(3 time points within 1 hour) and 1, 2, 4, 6, 8 (±10 minutes) hours after administration of NS-018, Cycle 1 Day 15: 2 (±10 minutes) hours after administration of NS-018, 
Cycle 2 Day 1: Predose (within 1 hour) and 1, 2, 4 (±10 minutes) hours after administration of NS-018, and Cycle 4 Day 1 and thereafter every 3 cycles: 2 (±10 minutes) hours 
after administration of NS-018. Subjects transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have ECG done at Cycle 7 Day 1 and will follow the same visit 
schedule (Cycle 7 Day 15, Cycle 8 Day 1, Cycle 10 Day 1 and thereafter Day 1 of every 3 cycles). 
h 
Within 28 days prior to the first dose of study drug.  However, bone marrow assessment performed within 6 months prior to the first dose can be used as baseline. 
i 
During the screening period, subject will complete the MF-SAF v4.0 assessment daily. The first 7 consecutive days of diary data will be used for eligibility assessment. Subject 
will complete the MF-SAF from Day −7 of Cycle 1 Day 1 to the end of Cycle 6 (Day 168) and the last 7 days in each cycle thereafter until the end of Cycle 12 (Day 336) for 
efficacy assessment. 
j 
The PROMIS questionnaire must be completed daily during the screening period and the last 7 days of each cycle until the end of Cycle 12 (Day 336).  This assessment will be 
performed for all subjects including subjects transitioning from BAT to NS-018. 
k 
If not done within the previous 8 weeks. 
l 
Within 14 days after last dose of study treatment or within 14 days after withdrawal from the study. 
m Randomization can be done within Day −4 so that the subject can start study treatment on the morning of Day 1. 
n 
In the BAT treatment arm (control group), after subjects have completed treatment with BAT at the end of Cycle 6, the Investigator will determine whether subjects should 
continue BAT treatment outside the study or discontinue BAT and transition to NS-018 at Cycle 7 Day 1.  During this transition period, subjects treated with ruxolitinib will be 
required to taper off this treatment before initiation of NS-018.  The dose of ruxolitinib should be decreased every 7 days by up to 50% until the smallest dose possible has been 
given for a minimum duration for the total tapering period of 14 days.  Ruxolitinib should then be stopped 1 day before starting NS-018.  Subjects who are taking 5 mg QD of 
ruxolitinib are already on the lowest dose possible; therefore, tapering is not applicable in this case.  If recurrence of MF-related symptoms (upon discontinuation of ruxolitinib 
therapy) is noted, it is strongly suggested that therapy with ruxolitinib be restarted.  If restart is not possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg 
QD) is recommended.  Subjects receiving treatment other than ruxolitinib will undergo a minimum washout period of 1 week (7 days) prior to start of NS-018 treatment. 
o 
Subjects who discontinue study treatment or withdraw from the study will be asked to complete the end of study procedures within 14 days after the last dose.  If the end of 
study procedures occur at a regular scheduled visit, these procedures may be performed at that time.

2.0 INTRODUCTION 
NS-018 (Ilginatinib) is a potent and specific Janus kinase 2 (JAK2) inhibitor which was designed 
and synthesized by Nippon Shinyaku Co., Ltd.  NS-018 is being developed as a therapeutic agent 
for myeloproliferative neoplasm (MPN) including myelofibrosis (MF). 
2.1 
Study Rationale 
A Phase 1/Phase 2, multicenter, dose-escalation, open-label study of NS-018 was conducted in 
subjects with primary myelofibrosis (PMF; defined in Appendix 9), post-polycythemia vera MF 
(PVMF; defined in Appendix 10), or post-essential thrombocythemia MF (ETMF; defined in 
Appendix 11) with 10 dosing cohorts (Study No. NS-018-101 [NCT01423851]).  A total of 
48 evaluable subjects were enrolled in the Phase 1 part of the study.  Sequential cohorts of 3 to 
6 subjects each were treated with escalating doses of NS-018.  Subjects self-administered 
NS-018 orally.  The starting dose of NS-018 was 75 mg daily.  The 10 dosing cohorts were: 
75 mg once daily (QD), 100 mg twice daily (BID), 125 mg QD, 200 mg QD, 200 mg BID, 
250 mg BID, 300 mg QD, 300 mg BID, 400 mg QD, and 400 mg BID.  Subjects were 
continuously treated with NS-018, administered daily therapy in 28-day cycles, until disease 
progression, whenever the product was tolerated.  The 300 mg QD dose was selected for use in 
the Phase 2 part of the study.  A total of 29 evaluable subjects were enrolled in the Phase 2 part 
of the study.  Subjects were continuously treated with NS-018, administered daily therapy in 
28-day cycles, until disease progression, whenever the product was tolerated.   
Responses  
In the Phase 1 part of Study NS-018-101, the best response in palpable spleen size reduction of 
≥50% observed was similar between subjects administered with 300 mg QD and BID, which is 
56% (5/9) and 50% (3/6), respectively.1  
In the Phase 2 part of Study NS-018-101, spleen volume reduction (SVR) was measured by 
magnetic resonance imaging (MRI) or computed tomography (CT) scan.  Only 1 subject had 
≥35% reduction in spleen size volume at Cycle 7 as measured by MRI and a baseline platelet 
count of <50,000/μL. 
Safety findings  
The maximum tolerated dose (MTD) was not reached during the Phase 1 part of 
Study NS-018-101 study; however, the Safety Review Committee (SRC) considered the 400 mg 
QD and BID cohorts not tolerable based on the proportion of drug-related neurological adverse 
events (AEs).  A treatment-emergent AE (TEAE) was reported for all 48 subjects (100%) during 
the study and Grade 3 or 4 TEAEs were reported for 35 of 48 subjects (72.9%).  The most 
frequently reported drug-related TEAEs were dizziness (11 of 48 subjects [22.9%]), anemia 
(10 of 48 subjects [20.8%]), thrombocytopenia (10 of 48 subjects [20.8%]),

47 
nausea (9 of 48 subjects [18.8%]), and diarrhea (7 of 48 subjects [14.6%]).  The majority of the 
drug-related TEAEs reported were Grade 3 in severity (16 of 48 subjects [33.3%]).  No deaths 
were reported during the study.  Any serious TEAEs were reported for 23 of 48 subjects (47.9%) 
and Grade 3 or 4 serious TEAEs were reported for 19 of 48 subjects (39.6%).  Treatment-
emergent AEs leading to discontinuation of study drug were reported for 14 of 48 subjects 
(29.2%).  There were no apparent dose-related trends in the incidence of TEAE across the 
treatment groups.  The SRC determined that 400 mg QD and BID were not tolerated based on 
the proportion of drug-related neurological AEs.  Dose-limiting toxicities were observed in 2 
subjects: Grade 3 QT prolongation in 1 subject in the 250 mg BID cohort and Grade 3 dizziness 
in 1 subject in the 400 mg BID cohort.  The subject with Grade 3 QT prolongation recovered 
following NS-018 discontinuation.  This was the only case of QT prolongation observed in the 
study.  This was also attributed to the subject’s prior cardiac history and the SRC concluded that 
it did not represent an overall issue for the study.  The most common drug-related hematologic 
events were thrombocytopenia and anemia.  Drug-related Grade 3/4 thrombocytopenia was 
reported for 13% (2/15) and 8% (1/12) in 300 mg QD and 300 mg BID, respectively.  Drug-
related Grade 3/4 anemia was reported for 0% and 17% (2/12) in 300 mg QD and 300 mg BID, 
respectively.  The safety assessment of 300 mg QD showed no clear difference from 300 mg 
BID in terms of drug-related non hematological AEs (gastrointestinal disorders 4/15 [27%] 
versus 6/12 [50%]; nervous system disorders 6/15 [40%] versus 5/12 [42%]), with dizziness and 
nausea the most common toxicities in these classes, respectively.   
In the Phase 2 part of Study NS-018-101, a TEAE was reported for all 29 subjects (100%) during 
the study.  The most frequently reported drug-related TEAEs were diarrhea (34.5%), anemia 
(27.6%), fatigue (24.1%).  The majority of the TEAEs reported were Grade 3 in severity 
(48.3%).  Drug-related Grade 3 anemia and Grade 3 thrombocytopenia were reported for 
21% and 3%, respectively.  No case of Grade 4 TEAE was reported.  A TEAE of Grade 5 in 
severity was reported for 1 of 29 subjects (3.4%). 
Pharmacokinetics 
The pharmacokinetics (PK) parameters of NS-018 were assessed in 43 subjects.  On Day 8, 
maximum plasma concentration (Cmax) was achieved 1 to 3 hours postdosing for all the dose 
cohorts.  Based on Cmax assessments on Day 8, systemic exposure of NS-018 was approximately 
dose proportional.  The half-life of NS-018 was 2 to 4 hours.  There was no evidence of drug 
accumulation as drug exposure was not substantially different between Day 8 and Day 29. 
Based on the efficacy, safety, and PK data of the Phase 1/Phase 2 study (Study No. NS-018-101), 
the 300 mg BID dose of NS-018 will be examined in this Phase 2b, open-label, multicenter, 
randomized, controlled, 2-arm study (Study No. NS-018-201).

2.2 
Background 
Myelofibrosis is a BCR-ABL1-negative MPN characterized by bone marrow fibrosis, anemia, 
progressive splenomegaly, extramedullary hematopoiesis (EMH), debilitating constitutional 
symptoms, cachexia, leukemic progression, shortened survival, and compromised quality of life 
(QoL).2, 3, 4  Myelofibrosis may be de novo (PMF) or secondary to polycythemia vera or essential 
thrombocythemia.  Approximately 90% of patients with MF carry mutations in any of the 3 
driver genes: JAK2 in approximately 60% of cases, calreticulin in approximately 20%, and 
myeloproliferative leukemia virus oncogene in approximately 10%.5, 6  Mutant proteins activate 
the JAK/signal transducers and activators of transcription pathway and other pathways 
downstream, leading to myeloproliferation, proinflammatory cytokine expression, and bone 
marrow remodeling.7, 8  
Because MF is associated with a heterogenous clinical phenotype, stratifying patients by 
prognosis can facilitate choice of appropriate treatment and identify candidates for high-risk 
procedures such as transplant.9  The International Prognostic Scoring System (IPSS), used at 
diagnosis, utilizes 5 independent predictors of inferior survival to determine disease risk in 
primary MF: age >65 years, hemoglobin <10 g/dL, white cell count >25 × 109/L, circulating 
blasts ≥1%, and presence of constitutional symptoms.10  The presence of 0, 1, 2, or ≥3 adverse 
features indicates low-, intermediate 1-, intermediate 2-, or high-risk disease, respectively, and 
corresponding median survival times range from approximately 11.3 to 2.3 years.  The Dynamic 
International Prognostic Scoring System (DIPSS) can be used to stratify prognosis at any time 
during the disease course.11  The DIPSS includes the same 5 prognostic factors as the IPSS but 
ascribes greater weight to low hemoglobin (2 points instead of 1); risk scoring is modified 
accordingly, and corresponding median survival estimates for low-, intermediate 1-, 
intermediate 2-, and high-risk diseases range from not reached to 1.5 years (Appendix 12).  The 
subsequent DIPSS-Plus includes 3 additional independent prognostic factors: red blood cell 
(RBC) transfusion dependence, platelet count <100 × 109/L, and unfavorable karyotype.12  
Until 2019, ruxolitinib, a dual JAK1/JAK2 inhibitor that was approved by the United States (US) 
Food and Drug Administration (FDA) in 2011 and by the European Medicines Agency in 2012, 
was the only available drug indicated for treatment of intermediate- and high-risk MF.  Evidence 
suggests there may be a survival benefit with ruxolitinib compared with conventional therapies.  
Patients treated with ruxolitinib frequently experience gradual loss of response, have a 
suboptimal response or develop cytopenias during treatment, resulting in ruxolitinib 
discontinuation within a few months and therefore, a subsequent risk of disease rebound.  In the 
Phase III COMFORT-I and COMFORT-II trials, pooled ruxolitinib discontinuation rates at 
3 and 5 years were approximately 50% and approximately 70%, respectively.  Suboptimal 
ruxolitinib dosing to avoid treatment-related AEs, at least initially, appears to be relatively 
common.13, 14, 15, 16, 17

Fedratinib is an oral, JAK2 inhibitor with activity against wild-type and mutationally activated 
JAK2 and FMS-like tyrosine kinase 3.18  In August 2019, the US FDA approved fedratinib for 
treatment of adult patients with intermediate-2 or high-risk primary or secondary MF.  The 
National Comprehensive Care Network (NCCN) clinical practice guidelines for treatment of 
MPNs now includes fedratinib as an option for patients with intermediate-2 or high-risk MF with 
platelet count ≥50 × 109/L, used as initial therapy or as second-line therapy for patients 
previously treated with ruxolitinib.19 
Despite the benefits reported with ruxolitinib as the first‑line treatment, a high proportion of 
patients discontinued treatment; the 1-, 2-, and 3-year discontinuation rates are 49%, 71%, and 
86%, respectively.20, 21  For patients who discontinue treatment with ruxolitinib, the median 
overall survival is dismal and ranges from 13 to 16 months.22, 23  There remains a great unmet 
need for patients who are nonresponsive to and have discontinued treatment with a JAK 
inhibitor. 
A detailed description of the chemistry, pharmacology, safety, and key findings of nonclinical 
and clinical studies for NS-018 is provided in the current Investigator’s Brochure (IB). 
2.3 
Benefit/Risk Assessment 
NS-018 is currently being developed as a therapeutic agent for MPN including MF.  NS-018 has 
been shown to have specificity for inhibiting activated JAK2 and is expected to have a wide 
therapeutic range, providing a satisfactory margin of safety between its efficacy and its safety.  
In the Phase 2 part of the Phase 1/Phase 2 study, 15 out of 20 subjects had an SVR of 0% to 50% 
at Cycle 7 since baseline.  One subject who had a baseline platelet count of <50,000/μL, 
achieved ≥35% SVR at Cycle 7.  The available safety data in the Phase 1/Phase 2 study indicate 
an overall acceptable safety and tolerability profile for NS-018.  Based on these data, NS-018 is 
considered to have a positive benefit-risk ratio for the treatment of subjects with MF and with 
platelet count of <50,000/μL.   
Treatment with specific therapy such as the JAK inhibitor, ruxolitinib, was observed in minority 
of patients with platelets below 100,000/µL, which is in line with previous reports.  Although 
there are case reports and series in which JAK inhibitors have been used successfully with 
improvement of platelet count,24, 25 JAK inhibitors are not recommended for patients with severe 
thrombocytopenia according to the NCCN clinical practice guidelines for treatment of MPNs.  
The management of severe thrombocytopenia remains unresolved, and future studies focused on 
patients with low platelets are deeply needed, to extend their extremely limited treatment 
armamentarium.  Several reports showed additional significant negative impact of severe 
thrombocytopenia (<50,000/µL) on prognosis of these patients,26, 27 but little is known about the 
impact of severe thrombocytopenia on the outcome of patients with PMF versus post-PVMF 
versus post-ETMF.  The fact that 1 subject with a baseline platelet count of <50,000/μL achieved 
≥35% SVR at Cycle 7 of the NS-018 clinical study as well as the current clinical situation

described above, it would be worth considering that NS-018 may have a positive benefit-risk 
ratio for the treatment of subjects with MF with platelet count of <50,000/μL. 
See Section 4.0 for details of study procedures, dose, and study design justification.

expected AEs of NS-018 may be found in the IB.

4.0 STUDY DESIGN 
4.1 
Overall Design 
This is a Phase 2b, open-label, multicenter, randomized, controlled, 2-arm study in subjects with 
PMF (Appendix 9), post-PVMF (Appendix 10), or post-ETMF (Appendix 11) to compare the 
efficacy and safety of NS-018 versus best available therapy (BAT).  Subjects will be stratified at 
baseline by spleen volume, and by history of prior JAK inhibitor treatment, and randomized to 
receive either NS-018 or BAT (control group).  The stratification factors will be as follows: 
1) spleen volume 
; 2) JAK inhibitor (naïve versus prior 
treatment).  There will be no MF-directed treatment (other than JAK inhibitor) for at least 
2 weeks prior to initiation of NS-018 or BAT.  A total of 120 subjects are expected to be enrolled 
and randomized 1:1 to either NS-018 or BAT. 
The population for this study includes male and female subjects who are 18 years of age or older 
with PMF, post-PVMF, or post-ETMF with severe thrombocytopenia (platelet count 
<50,000/µL), including subjects with DIPSS intermediate-2 or high-risk MF, and who require 
therapy.  Subjects must have a spleen volume of at least 450 cm3 measured by MRI (or by CT for 
applicable subjects) and have an Eastern Cooperative Oncology Group (ECOG) performance 
status of ≤2 (Appendix 13) at study entry (screening).  Subjects may or may not have received 
prior therapy for MF including JAK inhibitor. 
Individual subject participation in the study will depend upon the ability to tolerate the treatment 
regimen and upon the time to a progression event mandating study withdrawal. 
The screening period is 28 days before start of treatment.  During screening, all subjects will be 
evaluated for active tuberculosis (except in UK).  Additionally, inactive (latent) tuberculosis 
testing will be done in UK and South Korea by local laboratory for all subjects.  At Cycle 1 Day 
1, before the subject starts study treatment, all eligibility criteria including the subject’s status for 
coronavirus disease 2019 (COVID-19) should be reviewed and confirmed.  All subjects will be 
treated from Cycle 1 Day 1 through the end of the study.  There will be an indefinite period from 
Cycle 7 Day 1 until the subject meets the criteria for the discontinuation of study treatment (see 
Section 7.1), or until 3 years (expected) after the first subject in, whichever comes first.  Subjects 
who complete the treatment period will complete the end of study procedures within 14 days 
after the last dose.   
Subjects who discontinue prior to completing the treatment period will be asked to complete the 
end of study procedures within 14 days after the last dose (see Schedule of Assessments [SoA], 
Section 1.3).  For sites in South Korea, UK, and Germany, see SoA in Appendix 15,  
Appendix 16, and Appendix 17, respectively. 
If the end of study procedures occurs at a regular scheduled visit, these procedures may be 
performed at that time.

54 
A 30-day follow-up phone call will be scheduled after completion of the end of study 
procedures. 
NS-018 Dosage and Mode of Administration 
NS-018 will be self-administered orally at a dose of 300 mg BID.  The BAT will be administered 
according to product label and the Investigator’s discretion. 
Best Available Therapy Dosage 
The Investigator will decide the BAT that will be administered to the subject during the 
screening period based on subject’s condition.  The BAT must be one of the following: 
hydroxyurea, danazol, fedratinib, ruxolitinib, interferon, corticoid, erythropoietin, purinethol, 
thalidomide, lenalidomide or ‘supportive care/therapy’.  The BAT should be administered 
according to the manufacturer’s instructions or the Investigator’s discretion.  The BAT 
‘supportive care/therapy’, refers to use of blood products, fluids (crystalloids), pain medications, 
and/or antibiotics, that subjects will need to manage myelofibrosis symptoms and complications.  
Subjects in the control group will receive BAT at doses and schedules selected by the 
Investigator based on the subject’s condition and according to the manufacturer’s instructions or 
the Investigator’s discretion.  The BAT must be a single agent and cannot be combined with 
other agents.  JAK inhibitor can be allowed as BAT if the JAK inhibitor was administered as a 
standard of care based on the product label or Investigator’s discretion. The BAT may be 
changed at any time during the randomized treatment period based on the Investigator’s clinical 
assessment of the subject’s condition. However, it is not allowed to change the BAT to JAK 
inhibitor if it was not used as standard of care treatment prior to study participation.  No 
experimental agents (ie, those not approved for any indication) may be used at any time. 
Genetic Substudy 
In this study, DNA/RNA testing will be conducted.  In DNA testing, mutated genes are detected.  
The main purpose of DNA testing is to investigate a relationship between clinical benefit and 
genetic background.  In RNA testing, an expression of mRNAs is measured.  The main purpose 
of RNA testing is to investigate a more precise mechanism of action of NS-018 and/or explore 
currently unknown underlying pathophysiology of MPNs with special reference to treatment.  
This genetic substudy will be conducted after subjects have signed an optional genetic substudy 
consent form. 
Study Visits 
Subjects will have regular scheduled study visits at screening, Day 1 and Day 15 of 
Cycles 1, 2, 3, 4, 5, and 6, and Day 1 of every cycle thereafter.  One cycle is 28 days. Subjects 
transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have safety laboratory 
assessments performed on Day 1 and Day 15 of each cycle for 6 cycles.  Safety laboratory 
assessments will continue on Day 1 of the following cycles until the end of the study and will be

55 
done by a central laboratory (refer to Appendix 17 SoA for further details).  Additional local 
laboratory assessments may be performed per the Investigator’s discretion to monitor safety and 
document AEs as per local standards of care.     
Subjects in South Korea only, safety laboratory assessments will be performed weekly at Cycle 1 
on Day 1, Day 8, Day 15, and Day 22, and Cycles 2 through 6 will be performed on Days 1 and 
15, and Day 1 of each cycle thereafter.   For subjects who transition to NS-018, safety laboratory 
assessments will be performed on Day 1 and Day 15 of each cycle for the first 6 cycles after 
transitioning to NS-018 (including the additional visits on Day 8 and Day 22 of the first cycle 
after transitioning).  Laboratory visits on Day 8 and Day 22  of Cycle 1 for subjects randomized 
to NS-018 or Cycle 1 after transitioning to NS-018 in subjects who transition to NS-018 will be 
performed at the institutional local laboratory (refer to Appendix 15 for further details).  
Subjects who transition from BAT to NS-018 will have a physical examination done on Day 1 of 
each cycle for the first 4 cycles after transitioning to NS-018 and on Day 1 of every three cycles 
thereafter, as subjects are transitioned to NS-018.  Vital signs will be done on Day 1 of each 
cycle after transitioning to NS-018.  Vital signs will be taken within 3 hours before transitioning 
to NS-018.  ECG will be done on Day 1 and Day 15 of the first cycle and on Day 1 of the second 
and fourth cycles after transitioning to NS-018, and on Day 1 of every 3 cycles thereafter as 
subjects randomized to NS-018.  Each ECG measurement will be performed 2 hours 
(±10 minutes) postdose (refer to Section 8.2.3 and Appendix 16 for further details for UK).   
Subjects treated with ruxolitinib will be required to taper off ruxolitinib before initiation of NS-
018 at Cycle 1 Day 1.  The dose of ruxolitinib should be decreased every 7 days by up to 50% 
until the smallest dose possible has been given for a minimum duration of total tapering period of 
14 days.  Ruxolitinib should then be stopped 1 day before starting NS-018.  Subjects who are 
taking 5 mg QD of ruxolinitb, are already on the lowest dose possible, therefore, tapering is not 
applicable in this case.  If recurrence of MF-related symptoms (upon discontinuation of 
ruxolitinib therapy) is noted, it is strongly suggested that therapy with ruxolitinib be restarted.  If 
restart is not possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg QD) is 
recommended. 
Eligible subjects will receive NS-018 or BAT according to treatment assignment from Cycles 1 
to 6 until one of the following criteria for disease progression is met: 
1. Increase in spleen volume of ≥15% measured by MRI (or by CT for applicable subjects) 
from the baseline for subjects who are randomized to NS-018 or transitioned to NS-018. 
2. Splenic irradiation or splenectomy. 
3. Leukemic transformation defined by an increase in peripheral blood blast percentage to 
≥20% that is sustained for at least 8 weeks. 
4. Leukemic transformation defined by bone marrow blast count of ≥20%. 
5. Death.

56 
Subjects who meet the criteria for increase in spleen volume of ≥15% measured by MRI (or by 
CT for applicable subjects), leukemic transformation, or have had splenic irradiation will be 
discontinued from the study treatment and will be asked to complete the end of study procedures.  
Subjects randomized to the BAT arm (ie, subjects already on BAT or ‘supportive care/therapy’ 
and met all of the following criteria may transition to NS-018 treatment.   
 Subject has completed at least 24 weeks on BAT or had progression of disease prior to 
Week 24; progression must be declared based only on an increase in splenic volume of 
>15% measured by MRI (or by CT for applicable subjects) from baseline. 
 Subject has not undergone splenic irradiation or splenectomy. 
 Subject does not meet criteria for leukemic transformation. 
There will be no MF-directed treatment (other than ruxolitinib) for at least 1 week (7 days) prior 
to initiation of NS-018 after completion of BAT.  Changes in the MF-directed treatment should 
be documented.  
Subjects randomized to receive either NS-018 or BAT may continue to receive NS-018 after 
completion of Cycle 6.  In the BAT treatment arm (control group), after subjects have completed 
treatment with BAT at the end of Cycle 6, the Investigator will determine whether subjects 
should continue BAT treatment outside the study (ie, withdrawn from the study) or discontinue 
BAT and transition to NS-018 at Cycle 7 Day 1.  During this transition period, subjects treated 
with a ruxolitinib will be required to taper off this treatment before initiation of NS-018.  The 
dose of ruxolitinib should be decreased every 7 days by up to 50% until the smallest dose 
possible has been given for a minimum duration for the total tapering period of 14 days.  
Ruxolitinib should then be stopped 1 day before starting NS-018.  Subjects who are taking 5 mg 
QD of ruxolitinib, ruxolitinib, are already on the lowest dose possible; therefore, tapering is not 
applicable in this case.  If recurrence of MF-related symptoms (upon discontinuation of 
ruxolitinib therapy) is noted, it is strongly suggested that therapy with ruxolitinib be restarted.  If 
restart is not possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg QD) is 
recommended. 
Subjects receiving treatment other than ruxolitinib will undergo a minimum washout period of 1 
week (7 days) prior to start of NS-018 treatment.   
For subjects receiving BAT and transitioning to NS-018 before Cycle 7 Day 1, subjects will be 
required to taper off or washout this treatment before initiation of NS-018 as described above. 
Subjects may continue to receive treatment with NS-018 until the subject meets the criteria for 
discontinuation of study treatment (see Section 7.1), or until 3 years (expected) after the first 
subject is enrolled at any of the study centers, whichever comes first.

Visits for subjects in South Korea, UK, and Germany are detailed in a separate schedule of 
assessments (SoA) in Appendix 15, Appendix 16, and Appendix 17, respectively. 
4.2 
Scientific Rationale for Study Design 
This is a Phase 2b, open-label, multicenter, randomized, controlled, 2-arm study.  It will compare 
the efficacy and safety of NS-018 versus BAT in subjects with thrombocytopenia and primary 
MF, post-PVMF or post-ETMF.  A total of 120 eligible subjects are expected to be randomized 
in a 1:1 ratio to 1 of the 2 treatment arms. 
The NCCN clinical practice guidelines (2022 version 1.0) for treatment of MPNs recommends 
participating in clinical trial for patients with platelet counts of <50,000/μL.  In this study, both 
JAK inhibitor-naïve patients and patients who were previously treated with JAK inhibitor can be 
enrolled.  It is highly possible that symptoms and conditions differ very much among patients.  
Therefore, the BAT as comparator would be appropriate because the physician can select a 
treatment according to the subject’s disease status.    
4.3 
Justification for Dose 
The Maximum Tolerated Dose was not reached during the Phase 1 part of the NS-018-101 study; 
however, the Safety Review Committee considered the 400 mg QD and BID cohorts not 
tolerable based on the proportion of drug-related neurological AEs.  Therefore, 300 mg BID is 
the maximum dose which can be administrated. 
In the Phase 1 part of study NS-018-101, the best response in palpable spleen size reduction of 
≥50% observed was similar between subjects administered with 300 mg QD and BID, which is 
56% (5/9) and 50% (3/6), respectively.  However, based on the balance of efficacy and safety 
results in the Phase 1 part, the 300 mg QD dose was selected as the dose for the Phase 2 part of 
study NS-018-101.  
In the Phase 2 part of the study, SVR was measured by MRI or CT scan.  There were no safety 
concerns in subjects administered with 300 mg QD, however, only 1 subject with a baseline 
platelet count of <50,000/μL achieved ≥35% reduction in spleen size volume as measured by 
MRI at Cycle 7.  
The clinical diagnosis of splenomegaly is defined as the organ palpable below the costal margin 
during physical examination.  However, the recognition of the spleen enlargement by means of 
imaging methods such as MRI or CT was proven to be more accurate and reliable and was used 
to measure ≥35% SVR as primary end point in pivotal study for other JAK2 inhibitors 
(ruxolitinib, fedratinib, and pacritinib).  Based on this information, the best response in palpable 
spleen size reduction of ≥50% observed was similar between 300 mg QD and BID, which could 
have shown measurable differences with the use of MRI or CT scans.  In the Phase 2 part, it was 
observed that subjects with higher area under the plasma concentration-time curve (AUC)

Final Protocol NS-018-201 - Protocol V3.0 
 
58 
obtained higher efficacy in terms of SVR and an improvement of symptoms.  This means that if 
SVR is measured by MRI/CT in the Phase 1 part, 300 mg BID might have had better efficacy 
data than 300 mg QD.  
Based on the efficacy, safety, and PK data of the Phase 1/Phase 2 study NS-018-101, 300 mg 
BID dose of NS-018 was determined for use in this Phase 2b study NS-018-201.  In case a dose 
reduction, dose interruption or dose re-escalation is necessary, the study treatment will be 
administered as described in Section 6.6. 
4.4 
End of Study Definition 
The planned end of study is defined as the scheduled date when the last subject enrolled 
completes the 30-day follow-up phone call after the completion of the end of study procedures.   
The total length of the study, from screening of the first subject to the 30-day follow-up phone 
call of the last subject, is expected to be 3 years.

5.0 STUDY POPULATION 
Prospective approval of protocol deviations to recruitment and enrollment criteria, also known as 
protocol waivers or exemptions, is not permitted. 
5.1 
Inclusion Criteria 
Subjects are eligible to be included in the study only if all of the following criteria apply: 
1. Able to provide written informed consent prior to enrollment into the study. 
2. Males and females ≥18 years of age. 
3. Primary MF, post-PVMF or post-ETMF according to the DIPSS risk categories of 
intermediate-2 or high-risk MF (see Appendix 12). 
4. Spleen volume of at least 450 cm3 measured by MRI (or by CT for applicable subjects).  
This baseline scan will be centrally reviewed for spleen volume. 
5. Total symptom score (TSS) ≥10 on MF-SAF v4.0.  The TSS from the first 7 consecutive 
days of entry through the screening period will be used for eligibility.  
6. Platelet count < 50,000/µL.  Two results taken at least 7 days apart during screening are 
needed.  Each result must be <50,000/µL. 
7. No MF-directed treatment (other than ruxolitinib) for at least 2 weeks prior to initiation 
of NS-018, including erythropoietic, thrombopoietic agent, or any use of corticosteroids 
for MF symptom or blood count management.  Low dose corticosteroids <10 mg/day 
prednisone or equivalent is allowed for non-MF purposes.  Subjects treated with 
ruxolitinib will be required to taper off ruxolitinib before initiation of NS-018 at Cycle 1 
Day 1.  The dose of ruxolitinib should be decreased every 7 days by up to 50% until the 
smallest dose possible has been given for a minimum duration for the total tapering 
period of 14 days.  Ruxolitinib should then be stopped 1 day before starting NS-018.  
Subjects who are taking 5 mg QD of ruxolitinib are already on the lowest dose possible; 
therefore, tapering is not applicable in this case.  If recurrence of MF-related symptoms 
(upon discontinuation of ruxolitinib therapy) is noted, it is strongly suggested that therapy 
with ruxolitinib be restarted.  If restart is not possible, then prompt therapy with 
corticosteroids (eg, prednisone 60 mg QD) is recommended.   
Subjects who are not benefitting from ruxolitinib treatment may be enrolled in the study 
per the Investigator’s discretion. 
8. ECOG performance status ≤2. 
9. QTcF ≤480 msec. 
10. Peripheral blood blast count <10%. 
11. Estimated creatinine clearance ≥40 mL/min/1.73 m2 calculated using the Cockcroft and 
Gault equation.

Screen Failures 
Screen failures are defined as subjects who consent to participate in the clinical study but are not 
subsequently randomly assigned to study treatment via the Interactive Web Response System 
(IWRS).  A minimal set of screen failure information is required to ensure transparent reporting 
of screen failure subjects to meet the Consolidated Standards of Reporting Trials publishing 
requirements and to respond to queries from regulatory authorities.  Minimal information 
includes demography, screen failure details, eligibility criteria, and any serious adverse event 
(SAE). 
Individuals who do not meet the criteria for participation in this study (screen failure) may be 
rescreened one time.  Rescreened subjects should be given a new screening number  and will 
require re-consenting.  .

Preparation/Handling/Storage/Accountability 
NS-018 tablets should be stored 
 in a pharmacy or a locked and 
secure storage facility, accessible only to those individuals authorized by the Investigator to 
handle the study treatment. 
BAT storage requirements as described in the product insert(s) should be followed. 
Maintenance of a temperature log is mandatory. 
1. The Investigator or designee must confirm appropriate temperature conditions have 
been maintained during transit for all study treatment received and any discrepancies 
are reported and resolved before use of the study treatment. 
2. Only subjects enrolled in the study may receive study treatment and only authorized 
study center staff may supply or administer study treatment.  All study treatments must 
be stored in a secure, environmentally controlled, and monitored (manual or 
automated) area in accordance with the labeled storage conditions with access limited 
to the Investigator and authorized study center staff. 
3. The Investigator, institution, or the head of the medical institution (where applicable) 
is responsible for study treatment accountability, reconciliation, and record 
maintenance (ie, receipt, reconciliation, and final disposition records). 
4. Further guidance and information for the final disposition of unused study treatment 
are provided in the Study Reference Manual.  
The Investigator, a member of the study center staff, or a hospital pharmacist must maintain an 
adequate record of the receipt and distribution of all study treatment using the Drug 
Accountability Log.  These logs must be available for inspection at any time.  A Drug 
Accountability Log should also be maintained for the BAT(s) given to the subjects. 
6.3 
Measures to Minimize Bias: Randomization and Blinding 
This is a Phase 2b, open-label, multicenter, randomized, controlled 2-arm study.  If the subject is 
eligible to participate in the study, the subject will be assigned to receive either NS-018 or BAT.  
A total of 120 subjects are expected to be enrolled into the study and randomized in a 1:1 ratio to 
receive either NS-018 or BAT during the treatment period (Cycle 1 to Cycle 6).  Approximately 
60 subjects will be randomized to receive NS-018 and approximately 60 subjects will be 
randomized to receive BAT.   
Randomization will occur centrally by the IWRS.  Randomization will be stratified by spleen 
volume and a history of prior JAK inhibitor treatment (naïve versus prior treatment). 
Spleen volume will be assessed by the central reader who will be blinded to treatment 
assignments.  Details of the central assessments of spleen volume will be described in an 
imaging review charter.

NS-018 Study Treatment Compliance 
The prescribed dosage, timing, and mode of administration may not be changed, except as 
defined in Section 6.6.  Any departures from the intended regimen must be recorded in the 
electronic case report form (eCRF). 
Subject compliance will be monitored by assessing the tablet count from each of the dispensed 
bottles and returned at each visit.  Subjects will complete a study treatment dosing diary that will 
document the time of day they took their study treatment.  Tablet counts will be compared by the 
site to the dosing diary to further assess compliance and aid subject education regarding 
compliance.  Documentation on the eCRF will account for subject compliance in each treatment 
arm.  Subjects will be instructed to return any unused study treatment when attending clinic visits 
or if the subject is discontinued before the study is complete. 
Subjects who take <80% of the expected prescribed regimen will be counseled on the importance 
of good compliance to the study dosing regimen.  If compliance is <80% during the first month 
of therapy, the subject will be counseled, remain on study treatment, and will follow the study 
assessment schedule.   
Noncompliance is defined as taking less than 80% (underdose) or more than 100% (overdose) of 
study treatment during any evaluation period (visit to visit).  Both these situations should also be 
considered as protocol deviations. 
6.5 
Concomitant Therapy 
Any medication or vaccine (including over-the-counter or prescription medicines, vitamins, 
and/or herbal supplements) taken within 14 days of study drug administration will be considered 
a concomitant medication.  The site will also enter the subject’s prior therapies for MF.  Subjects 
taking medications chronically should be maintained on the same dose and dosing schedule, if 
medically feasible.  The product label of comparator therapies must be consulted and followed 
regarding concomitant therapies. 
Necessary supportive measures for optimal medical care will be given throughout the study, 
including intravenous antibiotics to treat infections, blood components, antidiarrheals, and 
antiemetics.  Additional care will be administered as indicated by the treating physician and the 
subject’s medical need.  No concomitant cytotoxic therapy, whether conventional or 
investigational, will be allowed during this study.  All concomitant medications and supportive 
therapy must be recorded on the eCRF along with: 
 Reason for use 
 Dates of administration including start and end dates 
 Dosage information including dose and frequency.

The Medical Monitor should be contacted if there are any questions regarding concomitant or 
prior therapy.   
A list of excluded medications/therapy is provided in Appendix 5. 
Routine prophylactic use of growth factors (granulocyte colony-stimulating factor, granulocyte 
macrophage-colony stimulating factor, and erythropoietin) or high dose steroids (>10 mg/day of 
prednisone or prednisone equivalent) is not permitted.  Therapeutic use should be considered at 
the treating physician’s discretion in subjects who develop complications secondary to 
cytopenias (eg, overt sepsis).  This should be discussed with the Medical Monitor, if at all 
possible, and documented.   
Blood products can be administered as needed.  
The potential for drugs which are metabolized by CYP enzymes to be affected by NS-018 is 
considered possible.  The plasma concentration of these drugs may increase or decrease when 
administered concomitantly with NS-018. 
Subjects currently taking medication that is substantially metabolized by CYP1A2 or CYP3A4 
(see Appendix 5) are not eligible for this study.  Every effort should be made to change these 
medications to acceptable alternatives to allow subject enrollment. 
Subjects taking strong CYP3A4 inducers or strong CYP3A4 inhibitors (see Appendix 5) who 
cannot be safely switched to an acceptable alternative are excluded from the study. 
Use of moderate or weak CYP3A4 inducers or moderate or weak CYP3A4 inhibitors (see 
Appendix 5) is discouraged (alternative therapies should be considered) during the study, but 
does not disqualify the subject from study participation and does not require dose modification. 
No other drugs that directly treat MF are allowed during this study.  No other investigational 
agents and anticancer agents are permitted while on study.  Herbal medications should be 
discontinued and not initiated while participating in the study. 
Live vaccines are not allowed within 30 days prior to the first dose of study treatment and while 
participating in the study.  In case of other type of vaccines, the subject must consult with the 
Investigator before vaccination.  Non-live COVID-19 vaccines can be used according to the local 
vaccination requirements and recommendations when considered appropriate by the Investigator.  
Any vaccines should be recorded in the eCRF as a concomitant medication, including 
manufacturer, brand name, lot number if available, doses administered (first dose, second dose, 
etc.) with administration dates.

Dose Modification 
Subjects who present the following drug-related AEs must have study treatment interrupted and 
a dose reduction should be considered according to Table 4: 
 Grade 4 neutropenia 
 Grade 4 lymphopenia 
 Grade 4 thrombocytopenia with active bleeding 
 Grade 3 or 4 non-hematologic AEs except for nausea, vomiting and/or diarrhea adequately 
controlled with standard systemic medications (per “Management of non-hematologic AEs”).  
Additional information about AE grades (Common Terminology Criteria for AEs [CTCAE] 
version 5.0) is provided in Appendix 4.   
Study treatment administration may be interrupted for clinically significant AEs of ≥Grade 1 that 
do not meet the interruption criteria, at the discretion of the Investigator.  Once the AE has 
resolved to Grade 0 or 1, or to baseline level within 4 weeks of study drug interruption, the study 
treatment may be resumed at 1 dose level below.  
Subjects requiring a >4-week interruption in study treatment administration should be 
permanently discontinued from study participation.   
If a dose reduction is necessary, the study treatment will be administered as follows (Table 4): 
Table 4 
Study Treatment Administration in Case of Dose Reduction 
Starting dose 
300 mg BID 
Dose level −1 
200 mg BID 
Dose level −2 
100 mg BID 
Abbreviations: BID=twice daily. 
Dose reduction would be to the next lower dose level.  If the subject has been receiving starting 
dose, the next dose level will be level −1.  If the subject has already been receiving 200 mg BID, 
the next dose level will be level −2.  Further dose reductions are not allowed. 
Dose re-escalation is permitted upon resolution to ≤Grade 1 AEs, except for hematological AEs, 
if deemed appropriate by the Investigator and following discussion with the medical monitoring 
team and Sponsor.  In case of hematological AEs, dose re-escalation is determined by the 
Investigator and Medical Monitor. 
Dose delays or modifications for BAT should occur per Investigator’s discretion in accordance 
to approved prescribing information or institutional guidelines.

Management of non-hematologic AEs 
Grade 3 or Grade 4 non-hematologic AEs will require dose interruption or dose reduction per the 
above guidance.  For Grade 3 nausea, vomiting, and/or diarrhea should receive optimal treatment 
with antiemetics or antidiarrheals and persist for at least 72 hours despite the use of an optimal 
antiemetic or antidiarrheal regimen before being considered an AE requiring treatment 
interruption.  The optimal antiemetic regimen is to be determined by each Investigator and 
should at a minimum include a 5-hydroxytrptamine (5-HT3) antagonist (also called serotonin 
receptor antagonists or serotonin blockers).  The optimal antidiarrheal regimen is to be 
determined by each Investigator and should at a minimum include Imodium® (loperamide 
hydrochloride) or Lomotil® (diphenoxylate hydrochloride and atropine sulfate). 
Management of hematologic AEs 
NS-018 should be held for Grade 4 neutropenia, lymphopenia, or bleeding.  Treatment should be 
held until hematologic AE has resolved to baseline level within 4 weeks of study treatment 
interruption, or in a case of Grade 4 thrombocytopenia with active bleeding, until 1 week after 
the resolution of a bleed.  Upon restart, it is additionally recommended to reduce the dose 
according to Table 4.  If the treatment is interrupted for >4 weeks for recovery of hematologic 
toxicities, subjects will be permanently discontinued from the study.   
Blood products can be used as needed.  Use of growth factors (granulocyte colony-stimulating 
factor, granulocyte macrophage-colony stimulating factor, and erythropoietin) is not permitted. 
6.7 
Treatment after the End of the Study 
The Sponsor will evaluate the appropriateness of continuing to provide the study treatment to 
subjects who are benefiting from treatment.  Based on the benefit-risk profile, if the development 
of this investigational study treatment has not been discontinued and if not yet commercially 
available, post-study access may be provided in compliance with local regulations.

SUBJECT DISCONTINUATION/WITHDRAWAL  
7.1 
Discontinuation of Study Treatment 
Subjects will be permanently discontinued from the study under the following circumstances: 
 Clinical progression as determined by Investigator including but not limited to the following 
events as described in Section 4.1: 
 Leukemic transformation defined by an increase in peripheral blood blast percentage 
to ≥20% that is sustained for at least 8 weeks 
 Leukemic transformation defined by bone marrow blast count of ≥20% 
 Subject’s physician considers a change of therapy would be in the best interest of the subject 
 Death 
 Continued unacceptable AEs despite optimal treatment or dose reduction (see Section 6.6) 
 Need for any treatment not allowed by the protocol 
 Noncompliance with study treatment and/or study procedures, as judged by the Investigator 
and/or Sponsor (eg, failure to return for scheduled visits, failure to complete study 
assessments, failure to return study treatment, etc.) 
 Subjects requiring >4-week interruption in study treatment administration 
 Increase in spleen volume of ≥15% measured by MRI (or by CT for applicable subjects) 
from the baseline for subjects who are randomized to NS-018 or transitioned to NS-018. 
Subjects who are discontinued from study participation will be asked to undergo the end of study 
procedures within 14 days after the last dose of study treatment.  If the end of study procedures 
occurs at a regular scheduled visit, these procedures may be performed at that time.  Subjects 
who are discontinued will also be asked to undergo a 30-day follow-up phone call after 
completion of the end of study procedures (see SoA, Section 1.3).  If a subject who does not 
meet enrollment criteria is inadvertently enrolled, that subject must be discontinued from study 
treatment and the Sponsor/designee must be contacted immediately.  An exception may be 
granted in rare circumstances for which there is a compelling safety reason to allow the subject 
to continue.  In these rare cases, the Investigator must obtain documented approval from the 
Sponsor/designee to allow the subject to continue in the study. 
Subjects who discontinue study treatment will not be replaced. 
7.2 
Subject Withdrawal from the Study 
Subjects will be withdrawn from the study under the following circumstances: 
 Withdrawal of consent 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
72 
 Noncompliance with study treatment and/or study procedures, as judged by the Investigator 
and/or Sponsor (eg, failure to return for scheduled visits, failure to complete study 
assessments, failure to return study treatment, etc.) 
 Female subjects who become pregnant during the study or who fail to use adequate birth 
control if applicable (refer to pregnancy section) 
 Sponsor decision to terminate study. 
Subjects who are withdrawn will be asked to undergo the end of study procedures within 14 days 
after withdrawal from the study.  If the end of study procedures occurs at a regular scheduled 
visit, these procedures may be performed at that time.  Subjects who are withdrawn from the 
study will also be asked to undergo a 30-day follow-up phone call after the completion of the end 
of study procedures (see SoA, Section 1.3).  For subjects who withdraw their consent, the end of 
study procedures and/or the 30-day follow-up phone call will not be performed.  
If the subject withdraws consent for disclosure of future information, the Sponsor may retain and 
continue to use any data collected before such a withdrawal of consent.  If a subject withdraws 
from the study, the subject may request destruction of any samples taken and not tested, and the 
Investigator must document this in the study center study records. 
7.3 
Lost to Follow-up 
A subject will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study center.  
The following actions must be taken if a subject fails to return to the clinic for a required study 
visit: 
 The study center must attempt to contact the subject and reschedule the missed visit as soon 
as possible and counsel the subject on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the subject wishes to and/or should continue in the 
study. 
 Before a subject is deemed lost to follow-up, the Investigator or designee must make every 
effort to regain contact with the subject (where possible, 3 telephone calls and, if necessary, a 
certified letter to the subject’s last known mailing address or local equivalent methods).  
These contact attempts should be documented in the subject’s medical record. 
 Should the subject continue to be unreachable, the subject will be considered to have 
withdrawn from the study with a primary reason of lost to follow-up whenever possible.  
7.4 
Procedures for Discontinuation in Relation to COVID-19 
If a subject is diagnosed with COVID-19 or is suspected to have COVID-19 and an AE/SAE is 
reported (see Section 8.3.8), the Investigator should determine whether the subject’s study 
treatment should continue, be temporarily discontinued or permanently discontinued.   

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
73 
Subject safety is paramount, and the Investigator should continue to reassess the risk/benefit of 
continued study involvement for each subject.  
If a subject is unable to attend on-site visits for undergoing safety-related assessments as shown 
in the SoA (Section 1.3) for physical visits at study centers due to local public health rules, 
subject inability or subject/caregiver decision, the subject must be temporarily discontinued from 
study treatment, unless the safety-related assessments can be performed at the subject’s home by 
delegated study center staff. 
Such temporary discontinuation of study treatment does not mean discontinuation of follow-up.  
In case it is not possible to perform on-site visits, the study center staff should keep in close 
contact with the subject to maintain awareness of their status and on-site visits should be 
replaced by telephone contacts following the same procedures as detailed in the SoA 
(Section 1.3) for telephone visits. 
If a subject is temporarily discontinued from study treatment, every effort should be made to 
have the subject/caregiver return all unused study treatment and empty bottles to the study center 
and study center staff should perform accountability as described in Section 6.2. 
If this is not possible: 
 Subjects should be clearly instructed that, in case of any tablets leftover in bottles already 
dispensed to them, they are not allowed to take the study treatment if they are not visiting the 
study center. 
 Remaining study treatment should be returned during the first possible on-site visit. 
 Reasons for not returning the study treatment and instructions given to the subject should be 
thoroughly documented. 
According to the local public health rules and recommendations, as soon as the subject is able to 
undergo study protocol procedures, then the study treatment can be dispensed and treatment 
restarted. 
If a study center is impacted by COVID-19 in a way that results in an inability to perform study 
activities, the study monitor should be informed as soon as possible.

8.0 STUDY ASSESSMENTS AND PROCEDURES 
Subjects will have regular scheduled study visits at screening, Day 1 and Day 15 of 
Cycles 1, 2, 3, 4, 5, and 6, and Day 1 of every cycle thereafter (see SoA, Section 1.3).  One cycle 
is 28 days.  
Subjects transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have safety 
laboratory assessments performed on Day 1 and Day 15 of each cycle for 6 cycles.  Safety 
laboratory assessments will continue on Day 1 of the following cycles until the end of the study 
and will be done by a central laboratory.  Additional local laboratory assessments may be 
performed per Investigator’s discretion to monitor safety and document AEs as per local 
standards of care.   
For subjects in South Korea only, safety laboratory assessments will be performed weekly at 
Cycle 1 on Day 1, Day 8, Day 15, and Day 22, and Cycles 2 through 6 will be performed on 
Days 1 and 15, and Day 1 of each cycle thereafter.  For subjects who transition to NS-018, safety 
laboratory assessments will be performed on Day 1 and Day 15 of each cycle for the first 6 
cycles after transitioning to NS-018 (including the additional visits on Day 8 and Day 22 of the 
first cycle after transitioning).  Laboratory visits on Day 8 and Day 22 of Cycle 1 for subjects 
randomized to NS-018 or Cycle 1 after transitioning to NS-018 in subjects who transition to NS-
018 will be performed at the institutional local laboratory.  
Subjects who transition from BAT to NS-018 will have a physical examination done on Day 1 of 
each cycle for the first 4 cycles after transitioning to NS-018 and on Day 1 of every three cycles 
thereafter, as subjects are transitioned to NS-018.  Vital signs will be done on Day 1 of each 
cycle after transitioning to NS-108.  Vital signs taken within 3 hours before transitioning to NS-
018. Subjects transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have ECG
done at Cycle 7 Day 1 and will follow the same visit schedule (Cycle 7 Day 15, Cycle 8 Day 1,
Cycle 10 Day 1 and thereafter Day 1 of every 3 cycles) as subjects randomized to NS-018.  Each
ECG measurement will be performed at 2 hours (±10 minutes) postdose.

At Cycle 1 Day 1, before the subject starts study treatment, all eligibility criteria, including 
the subject’s COVID-19 status, should be reviewed and confirmed.

Study procedures and their timing are summarized in the Global SoA (Section 1.3),  
(Appendix 15), UK SoA (Appendix 16), and Germany SoA (Appendix 17).

Protocol waivers or exemptions are not allowed.

Immediate safety concerns should be discussed with the Sponsor immediately upon 
occurrence or awareness to determine if the subject should continue or discontinue study 
treatment.

Adherence to the study design requirements, including those specified in the SoA, is essential 
and required for study conduct.

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
75 
 All screening evaluations must be completed and reviewed to confirm that potential subjects 
meet all eligibility criteria.  The Investigator will maintain a screening log to record details of 
all subjects screened and to confirm eligibility or record reasons for screening failure, as 
applicable.  
The maximum amount of blood collected from each subject over the duration of the study, 
including any extra assessments that may be required, will adhere to the clinical guidance of no 
more than 15% over an individual assessment or a weekly/monthly assessment draw.  Repeat or 
unscheduled samples may be taken for safety reasons or for technical issues with the samples. 
Visits for subjects in South Korea, UK and Germany are detailed in a separate SoA in  
Appendix 15, Appendix 16, and Appendix 17, respectively. 
8.1 
Efficacy Assessments  
8.1.1 
Treatment Response 
Treatment response will be assessed using the International Working Group for Myelofibrosis 
Research and Treatment (IWG-MRT) and European LeukemiaNet (ELN) during the study at 
Cycle 2 Day 1, Cycle 3 Day 1, Cycle 4 Day 1, Cycle 7 Day 1, and at every 3 cycles thereafter 
(Day 1) (see SoA, Section 1.3).  The criteria are provided in Appendix 14. 
8.1.2 
Spleen Volume Assessment 
Magnetic resonance imaging is the imaging modality of choice for the measurement of spleen 
volume.  Subjects who have contraindications to MRI or subjects at sites where MRI is not 
available will be evaluated with CT scans.  Both MRI and CT scans will be performed without 
injection of contrast material.  Consistent imaging, ie, the same modality (MRI or CT) and the 
same technique must be used for a given individual subject throughout the study unless a new 
contraindication develops (such as claustrophobia) or the availability for the originally selected 
method is no longer possible.  Spleen volume will be assessed by limited central readers who 
will be blinded to treatment assignments and centrally adjudicated.  The full details of the central 
assessments of spleen volume will be described in an imaging review charter. 
Spleen volume will be assessed by MRI (CT scan for subjects not able to tolerate MRI) in all 
randomized subjects.  Spleen size measurement will be done at baseline (screening), Cycle 4 
Day 1, Cycle 7 Day 1, Cycle 10 Day 1 and Cycle 13 Day 1.  Details regarding the MRI/CT 
protocol will be provided in the Study Reference Manual.   
Subjects transitioning to NS-018 from BAT at Cycle 7 Day 1 will also have spleen volume 
measurement by MRI at Cycle 7 Day 1, Cycle 10 Day 1, and Cycle 13 Day 1.  
Subjects transitioning to NS-018 from BAT before Cycle 7 Day 1 (see Section 4.1, Study Visits) 
will have spleen volume measurement by MRI at Cycle 4 Day 1 per schedule.

8.1.3 
Bone Marrow Assessment 
Bone marrow assessment will be performed in subjects who are randomized to either NS-018 or 
BAT treatment arm.  Bone marrow will be assessed by aspiration and biopsy, according to 
standard practice at the site at baseline (screening), Cycle 13 Day 1 and at every 12 cycles 
thereafter.  Bone marrow assessment performed within 6 months prior to the first dose can be 
used as baseline  
8.1.4 
Myelofibrosis Symptom Assessment Form 
Myelofibrosis is a highly symptomatic MPN and causes both splenomegaly-related and 
constitutional symptoms.29  In addition to reducing spleen size, relieving symptom severity is a 
key objective of the treatment of MF.   
The MF-SAF v4.0 assesses the severity of 7 core symptoms of myelofibrosis: fatigue, night 
sweats, pruritus, abdominal discomfort, pain under the ribs on the left side, early satiety, and 
bone pain.  The MF-SAF v4.0 asks respondents to report symptom severity at its worst for each 
of the 7 items on a 0 (Absent) to 10 (Worst Imaginable) numeric rating scale.  The MF-SAF v4.0 
is scored as a unidimensional scale to create a TSS.  The TSS for the 24-hour recall (ie, daily 
diary) format is calculated as the sum of the 7 individual item responses on the 0 to 10 scale for a 
possible TSS range of 0 to 70.   
The 24-hour recall (ie, daily diary) format will be used in this study.  The 24-hour recall (daily 
diary) format asks subjects to rate the severity of each symptom at its worst during the past 
24 hours (Table 5). 
Table 5 
Items of Myelofibrosis Symptom Assessment Form v4.0 Diary 
1. During the past 24 hours, how severe was your worst fatigue (weariness, tiredness)? 
2. During the past 24 hours, how severe were your worst night sweats (or feeling hot or flushed)? 
3. During the past 24 hours, how severe was your worst itching? 
4. During the past 24 hours, how severe was your worst abdominal discomfort (feeling pressure or 
bloating)? 
5. During the past 24 hours, how severe was the worst pain under your ribs on your left side? 
6. During the past 24 hours, what was the worst feeling of fullness you had after beginning to eat? 
7. During the past 24 hours, how severe was your worst bone pain (not joint or arthritis pain)? 
 
During the screening period, subjects will complete the MF-SAF v4.0 assessment daily. The first 
7 consecutive days of diary data will be used for eligibility assessment.  Subjects will complete 
the MF-SAF daily from Day −7 of Cycle 1 Day 1 to the end of Cycle 6 (Day 168) and the last 7 
days in each cycle thereafter until the end of Cycle 12 (Day 336) for efficacy assessment.

The MF-SAF v4.0 is designed for electronic data collection by the subject and the electronic 
version will be used in this study.   
8.1.5 
Pharmacokinetics and Pharmacodynamics Assessments 
The PK/pharmacodynamic assessments will be performed in subjects who are randomized to 
NS-018 only.  Instructions for the processing, handling, and shipment of samples for central 
analysis will be provided in the Study Reference Manual. 
8.1.5.1 
Pharmacokinetics Assessments 
Blood samples will be obtained for PK assessments to analyze NS-018 and its metabolite, 
MPD-6007.  The intended time points are specified below for the study (see SoA, Section 1.3).  
Blood samples will be collected from subjects assigned to the NS-018 arm (60 subjects) during 
the randomized phase of the study at Cycles 1 and 2. 
 Cycle 1 Day 1: Predose (within 1 hour) and 0.5, 1, 2, 3, 4, 6, and 8 hours (±10 minutes per 
time point) after administration of NS-018. 
 Cycle 2 Day 1: Predose (within 1 hour) and 0.5, 1, 2, 3, 4, 6, and 8 hours (±10 minutes per 
time point) after administration of NS-018. 
The PK parameters to be estimated include observed Cmax, time to maximum plasma 
concentration (Tmax), AUC, terminal elimination half-life (t1/2), and accumulation ratio (AR). 
8.1.5.2 
Pharmacodynamic Assessments 
8.1.5.2.1 
Phospho-STAT3 Assessments 
The intended time points for phospho-STAT3 assessments are specified below for the study (see 
SoA, Section 1.3). 
 Cycle 1 Day 1: Predose (within 24 hours) and 3 (±10 minutes) hours after administration of 
NS-018. 
 Cycle 2 Day 1: Predose (within 1 hour) and 3 (±10 minutes) hours after administration of 
NS-018. 
Participation in phospho-STAT3 analysis (for NS-018 arm only) is optional and based on the 
site’s capability to process the sample prior to shipment to the central laboratory.   
8.1.5.2.2 
mRNA Sequencing (optional genetic substudy) 
The intended time points for mRNA sequencing are specified below for the study (see SoA, 
Section 1.3). 
 Cycle 1 Day 1: Predose (within 24 hours) and 8 hours (±10 minutes) after administration of 
NS-018. 
 Cycle 2 Day 1: Predose (within 1 hour).

Other Exploratory Assessments 
8.1.6.1 
Patient-Reported Outcomes Measurement Information System (PROMIS) Fatigue 
Short Form (F-SF) 7b 
The PROMIS F-SF is a suitable measure of fatigue.  The PROMIS Fatigue item banks assess a 
range of self-reported symptoms, from mild subjective feelings of tiredness to an overwhelming, 
debilitating, and sustained sense of exhaustion that likely decreases one’s ability to execute daily 
activities and function normally in family or social roles.  Fatigue is divided into the experience 
of fatigue (frequency, duration, and intensity) and the impact of fatigue on physical, mental, and 
social activities.   
The PROMIS F-SF 7b (daily) v1.0 will be used in this study.  The PROMIS 7b daily short form 
measures daily fatigue and asks the subject to evaluate the subject’s fatigue since waking up.   
The electronic version of the questionnaire must be completed daily by the subject during the 
screening period and the last 7 days of each cycle until the end of Cycle 12 (Day 336).30, 31  This 
assessment will be performed as defined in the SoA (Section 1.3) for all subjects including 
subjects transitioning from BAT to NS-018. 
8.1.6.2 
EQ-5D-5L 
The 5-level EQ-5D paper version (EQ-5D-5L; https://euroqol.org/eq-5d-instruments/eq-5d-5l-
about/) consists of 2 pages: the EQ-5D descriptive system and the EuroQoL visual analog scale 
(EQ VAS). 
The descriptive system comprises 5 dimensions: mobility, selfcare, usual activities, 
pain/discomfort, and anxiety/depression.  Each dimension has 5 levels: no problems, slight 
problems, moderate problems, severe problems, and extreme problems.  The subject is asked to 
indicate the subject’s health state by ticking the box next to the most appropriate statement in 
each of the five dimensions.  This decision results in a 1-digit number that expresses the level 
selected for that dimension.  The digits for the 5 dimensions can be combined into a 5-digit 
number that describes the subject’s health state. 
The EQ VAS records the subject’s self-rated health on a vertical VAS, where the endpoints are 
labelled “The best health you can imagine” and “The worst health you can imagine.”  The VAS 
can be used as a quantitative measure of health outcome that reflect the subject’s own judgement. 
The EQ-5D-5L should be collected within 24 hours prior to first dose, at Cycle 7 Day 1 and 
every 6 cycles thereafter.  The subject should complete the questionnaire before any other 
scheduled procedures are performed and dosing occurs. 
Note: Every attempt should be made to have the questionnaires completed according to the SoA.  
Given the importance of having a baseline questionnaire as well as a questionnaire at end of 
treatment collected, if the subject discontinues treatment for reasons not due to disease

79 
progression, questionnaires should be collected at the end of study visit (see Section 1.3 [SoA] 
for questionnaires to be collected).   
Subjects transitioning from the BAT to NS-018 treatment before Cycle 7 Day 1 will complete 
the EQ-5D-5L within 24 hours prior to administering NS-018, at Cycle 7 Day 1, and every 6 
cycles thereafter. 
8.2 
Safety Assessments  
Planned time points for all safety assessments are provided in the SoA (Section 1.3). 
8.2.1 
Physical Examinations 
Full physical examination, including weight and spleen size (by clinical assessment 
[palpation]), will be performed in accordance with the SoA (Section 1.3).   
For UK only, a skin examination will also be conducted as part of the physical examination 
(refer to Appendix 16 for further details). 
At screening, spleen size (palpation) measurement should be done on the same day the spleen 
volume is measured.  If the same day measurement is not feasible, the measurement should be 
assessed within 14 days prior to the first dose of study treatment.  
8.2.2 
Vital Signs 
The following vital signs will be assessed (within 3 hours predose) in accordance with the SoA 
(Section 1.3): 
 Blood pressure (systolic and diastolic [mmHg]) 
 Heart rate (beats per minute) 
 Body temperature (°C) 
 Respiration rate (breaths per minute). 
8.2.3 
Electrocardiograms 
Electrocardiogram  is required for all subjects at screening.  After screening, only subjects 
randomized to NS-018 will have ECGs done at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1, 
Cycle 4 Day 1, and Day 1 of every 3 cycles thereafter as detailed below.  
 Cycle 1 Day 1: Predose (3 time points within 1 hour) and 1, 2, 4, 6, 8 (±10 minutes) 
hours after administration of NS-018 
 Cycle 1 Day 15: 2 (±10 minutes) hours after administration of NS-018. 
 Cycle 2 Day 1: Predose (within 1 hour) and 1, 2, 4 (±10 minutes) hours after 
administration of NS-018 
 Cycle 4 Day 1 and thereafter every 3 cycles: 2 (±10 minutes) hours after 
administration of NS-018

For UK only, ECGs Cycle 1 Day 1: predose (3 time points within 1 hour) and 1, 2, 4, 6, 8 (±10 
minutes) hours after administration of NS-018, Cycle 1 Day 15: 2 (±10 minutes) hours after 
administration of NS-018, Cycle 2 Day 1: predose (within 1 hour) and 1, 2, 4 (±10 minutes) 
hours after administration of NS-018, Cycle 3 Day 1 predose (within 1 hour) and 1, 2, and 4 
(±10 minutes) hours after administration of NS-018, and Cycle 4 Day 1 and thereafter every 
3 cycles: 2 (±10 minutes) hours after administration of NS-018. NOTE: An additional single 
ECG will be done at Cycle 3 and Cycle 9, Day 1 predose (within 1 hour) and 1, 2, and 4 (±10 
minutes) hours after administration of NS-018 .  Refer to Appendix 16 for UK SoA for 
further details. 
 At screening, ECG will be used for eligibility determination and centrally read for all 
subjects.  Median QTcF must be ≤480 msec. 
 Triplicate (for screening, Cycle 1 and Cycle 2) and single and Cycle 4 and thereafter) 12-lead 
ECG (central read) will be obtained as outlined in the SoA (see Section 1.3) using an ECG 
machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTcF 
intervals.   
 At each time point at which triplicate ECGs are required, 3 individual ECG tracings should 
be obtained as closely as possible in succession, but no more than 2 minutes apart.  The full 
set of triplicates should be completed in less than 4 minutes. 
When time points for ECG measurements coincide with the time points for PK sampling, 
triplicate ECG collection should take place immediately prior to the collection of the plasma 
sample for PK. 
All ECGs will be read centrally.  If actions are triggered based on local read by the 
Investigator/study center they should be documented in source documents and corresponding 
eCRF sections.  Details regarding the ECG collection and reading will be provided in the Study 
Reference Manual. 
Subjects transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have ECG done on 
Day 1 and Day 15 of the first cycle of NS-018, Day 1 of the second and fourth cycles, and on 
Day 1 of every three cycles thereafter as subjects randomized to NS-018.  Each ECG 
measurement will be performed at 2 hours (±10 minutes) postdose. 
8.2.4 
Clinical Safety Laboratory Assessments 
Safety laboratory assessments (hematology, chemistry, and urinalysis) will be performed for 
both BAT and NS-018 treatment arms by a central laboratory by means of their established 
methods.  Additional local laboratory assessments may be performed per Investigator’s 
discretion to monitor safety and document AEs as per local standards of care.  Before starting the 
study, the Investigator will supply the Sponsor with a list of the normal ranges and units of 
measurement.   

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
81 
Subjects transitioning from BAT to NS-018 will have safety laboratory assessments performed 
on Day 1 and Day 15 of each cycle for 6 cycles.  Safety laboratory assessments will continue on 
Day 1 of the following cycles until the end of the study and will be done by a central laboratory 
(refer to Section 1.3 and Appendix 16 SoA for further details).  Additional local laboratory 
assessments may be performed at the Investigator’s discretion to monitor safety and document 
AEs as per local standards of care.  
Subjects in South Korea only, safety laboratory assessments will be performed weekly at Cycle 1 
on Day 1, Day 8, Day 15, and Day 22, and Cycles 2 through 6 will be performed on Days 1 and 
15, and Day 1 of each cycle thereafter.   For subjects who transition to NS-018, safety laboratory 
assessments will be performed on Day 1 and Day 15 of each cycle for the first 6 cycles after 
transitioning to NS-018 (including the additional visits on Day 8 and Day 22 of the first cycle 
after transitioning).  Laboratory visits on Day 8 and Day 22  of Cycle 1 for subjects randomized 
to NS-018 or Cycle 1 after transitioning to NS-018 in subjects who transition to NS-018 will be 
performed at the institutional local laboratory.  Visits for subjects in South Korea are detailed in 
a separate SoA in Appendix 15.  
 See Appendix 3 for the list of clinical laboratory tests to be performed (refer to the SoA for 
the timing and frequency).  
 The Investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the eCRF.  The 
laboratory reports must be filed with the source documents.  Clinically significant abnormal 
laboratory findings are those that are not associated with the underlying disease, unless 
judged by the Investigator to be more severe than expected for the subject’s condition. 
 All laboratory tests with values considered clinically significantly abnormal during 
participation in the study or within 30 days after the last dose of study treatment should be 
repeated until the values return to normal or baseline or are no longer considered clinically 
significant by the Investigator or Medical Monitor. 
 If such values do not return to normal/baseline within a period of time judged 
reasonable by the Investigator, the etiology should be identified and the Sponsor 
notified. 
 All protocol-required laboratory assessments, as defined in Appendix 3, must be 
conducted in accordance with the laboratory manual and the SoA. 
 If laboratory values from non-protocol specified laboratory assessments performed at 
the institution’s local laboratory require a change in subject management or are 
considered clinically significant by the Investigator (eg, SAE or AE or dose 
modification), then the results must be recorded in the eCRF.

8.3 
Adverse Events 
The definitions of an AE or SAE can be found in Appendix 4. 
Adverse events will be reported by the subject (or, when appropriate, by a caregiver, surrogate, 
or the subject’s legally authorized representative). 
The Investigator and any designees are responsible for detecting, documenting, and recording 
events that meet the definition of an AE or SAE and remain responsible for following up all 
AEs/SAEs.  All AEs/SAEs, whether related or not, should be followed until resolution or until 
30 days post close of the study. 
8.3.1 
Time Period and Frequency for Collecting AE and SAE Information  
All AEs, including SAEs, will be collected from the signing of the informed consent form (ICF) 
at the time points specified in the SoA (Section 1.3).  All preexisting medical conditions that are 
present prior to signing the ICF should be documented as part of the medical history. 
All SAEs will be recorded and reported to the Sponsor or designee within 24 hours, as indicated 
in Appendix 4.  The Investigator will submit any updated SAE data to the Sponsor within 
24 hours of it being available. 
Investigators are not obligated to actively seek AE or SAE after conclusion of the study 
participation.  However, if the Investigator learns of any SAE, including a death, at any time 
after a subject has been discharged from the study, and considers the event to be reasonably 
related to the study treatment or study participation, the Investigator must promptly notify the 
Sponsor. 
The method of recording, evaluating, and assessing causality of AE and SAE and the procedures 
for completing and transmitting SAE reports are provided in Appendix 4. 
8.3.2 
Method of Detecting AEs and SAEs 
Care will be taken not to introduce bias when detecting AEs and/or SAEs.  Open-ended and 
non-leading verbal questioning of the subject is the preferred method to inquire about 
AE occurrences.  
8.3.3 
Follow-up of AEs and SAEs 
After the initial AE/SAE report, the Investigator is required to proactively follow each subject at 
subsequent visits/contacts.  All SAEs, and serious or nonserious AEs of special interest (AESIs 
as defined in Section 8.3.6), will be followed until resolution, stabilization, the event is otherwise 
explained, or the subject is lost to follow-up (as defined in Section 7.3).  Further information on 
follow-up procedures is given in Appendix 4.  Following the 30-day window after last dose of 
study drug, only SAEs and AESIs considered as related/ potentially related to study drug should 
be reported.

8.3.4 
Regulatory Reporting Requirements for SAEs 
 Notification by the Investigator to the Sponsor/designee of an SAE within 24 hours is 
essential so that legal obligations and ethical responsibilities towards the safety of subjects 
and the safety of a study treatment under clinical investigation are met.  
 The Sponsor/designee has a legal responsibility to notify both the local regulatory authority 
and other regulatory agencies about the safety of a study treatment under clinical 
investigation.  The Sponsor/designee will comply with country-specific regulatory 
requirements relating to safety reporting to the regulatory authority, Institutional Review 
Boards (IRB)/Independent Ethics Committees (IEC), and Investigators. 
 Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and Sponsor/designee policy 
and forwarded to Investigators as necessary. 
 An Investigator who receives an Investigator safety report describing an SAE or other 
specific safety information (eg, summary or listing of SAEs) from the Sponsor/designee will 
review and document the review and then file it along with the IB and will notify the 
IRB/IEC, if appropriate according to local requirements. 
8.3.5 
Pregnancy 
Details of all pregnancies in female subjects and female partners of male subjects will be 
collected after the start of study treatment.   
The Investigator must follow the pregnancy either to term or termination and will collect data on 
both maternal and fetal outcomes until final outcome (ie, normal, abnormal including abortion).  
Pregnancy alone is not considered an AE. 
If pregnancy is reported, the Investigator should inform the Sponsor/designee within 24 hours of 
learning of the pregnancy and should follow the procedures outlined in Appendix 6. 
Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAEs. 
8.3.6 
Adverse Events of Special Interest 
The AESIs for this study may include bleeding of any grade, cardiac events of any grade, 
non-melanoma skin cancer, opportunistic infections such as herpes zoster, progressive multifocal 
encephalopathy, and tuberculosis.  Any development of tuberculosis will be recorded as an 
AESI. 
The AESIs should be promptly recorded in the eCRF so that the Independent Data Monitoring 
Committee (IDMC) and Medical Monitor are notified.  Such events will be reviewed and 
documented by the IDMC and Medical Monitor to enable consideration of implications for other 
subjects. 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
84 
The AESIs that qualify as SAEs should be reported according to Section 8.3.4 and Appendix 4. 
8.3.7 
Events and/or Disease-related Outcomes Not Qualifying as AEs or SAEs 
Events of progression of the underlying MF and events clearly related to the progression of the 
MF should not be reported as an AE or SAE.  These events will be recorded on the 
corresponding eCRF page in the subject’s eCRF. 
NOTE: However, if either of the following conditions applies, then the event must be recorded 
and reported as an AE or SAE if it meets the serious criteria:  
 The event is, in the Investigator’s opinion, of greater intensity, frequency, or duration than 
expected for the individual subject.  
OR 
 The Investigator considers that there is a reasonable possibility that the event was related to 
study treatment. 
Other events not considered SAEs for the purpose of this protocol are: 
 Overdose of study drug or concomitant medication unless associated with an SAE.  Note that 
these should be captured as an AE in the corresponding eCRF page. 
 Preplanned or elective hospitalization including social and/or convenience situations. 
 Hospital visits of less than 24 hours of duration which do not result in hospitalization. 
8.3.8 
Procedures in Relation to COVID-19 Infection 
If a subject presents with clinical signs and symptoms consistent with COVID-19 infection, the 
Investigator should request a test where possible and this should be recorded in the AE field of 
the eCRF as follows: 
 If test is positive, record as “COVID-19 confirmed”. 
 If test is negative, record the AE/SAE signs and symptoms and/or other diagnosis. 
 If test is not available and signs and symptoms, as judged by the Investigator, are highly 
suspicious of COVID-19 infection, record as “COVID-19 suspected”. 
If other concurrent diagnoses exist, eg, pneumonia, the Investigator should record as separate 
AEs. 
If an AE/SAE is associated with COVID-19, the Investigator should determine whether the 
subject’s treatment should continue, be temporarily interrupted, or permanently stopped.  Refer 
to Section 7.4 for discontinuation procedures in relation to COVID-19.  
All AE reporting instructions in this section and SAE reporting in Section 8.3 also apply to any 
AE/SAE associated with COVID-19.

8.4 
Treatment of Overdose 
For this study, any dose of NS-018 greater than 300 mg BID within a 24-hour time period will be 
considered an overdose.  For BAT, refer to the approved label/package insert for overdose 
information.   
The Sponsor does not recommend a specific treatment for an overdose.  In the event of an 
overdose, the Investigator should: 
1. Contact the Medical Monitor immediately. 
2. Closely monitor the subject for any AE/SAE and laboratory abnormalities until study 
treatment can no longer be detected systemically (at least 2 days). 
3. Obtain a plasma sample for PK analysis within 1 day from the date of the last dose of study 
treatment if possible and requested by the Medical Monitor (determined on a case-by-case 
basis). 
4. Document the quantity of the excess dose as well as the duration of the overdose in the eCRF. 
Decisions regarding dose interruptions or modifications will be made by the Investigator in 
consultation with the Medical Monitor based on the clinical evaluation of the subject. 
8.5 
Pharmacokinetics 
The PK parameters will include: 
Cycle 1 Day 1 
 Cmax  
 Tmax  
 Area under the plasma concentration-time curve (AUC0-24)  
 Terminal elimination phase rate constant (λz)   
 t½ 
 Apparent total body clearance (CL/F) 
 Apparent volume of distribution (Vz/F) 
 Lag time (Tlag) 
Cycle 2 Day 1 
 Cmax  
 Tmax  
 AUC0-24  
 λz  
 t½  
 AR = [AUC0-24] Cycle 2 Day 1/[AUC0-24] Cycle 1 Day 1  
 Average plasma concentration (Cav)

 Observed minimum plasma concentration (Cmin)   
 Percentage fluctuation  
 PTF % =100 × (Cmax − Cmin)/Cav 
 CL/F 
 Vz/F 
 Tlag 
 Whole blood samples of approximately 3 mL will be collected from subjects assigned to the 
NS-018 treatment arm only for measurement of plasma concentrations of NS-018 and 
MPD-6007 as specified in the SoA (Section 1.3).  A maximum of 8 samples may be collected 
including sample taken predose and samples taken at 0.5, 1, 2, 3, 4, 6, and 8 hours postdose.  
Instructions for the collection and handling of biological samples will be provided by the 
Sponsor/designee.  The actual date and time (24-hour clock time) of each sample will be 
recorded.  The time and date of study treatment administration and the subject’s most recent 
ingestion of drugs will also be recorded. 
 Samples will be used to evaluate the PK of NS-018 and MPD-6007.  Each plasma sample 
will be divided into 5 aliquots (for 2 primary PK samples and 3 back-up PK samples).  
Analyses of NS-018 and MPD-6007 plasma concentration may also be used to evaluate 
safety, efficacy or PK aspects related to concerns arising during or after the study. 
 Genetic analyses will not be performed on these plasma samples.  Subject confidentiality will 
be maintained.  At visits during which plasma samples for the determination of NS-018 will 
be taken, 1 sample of sufficient volume can be used. 
Any changes in the timing or addition of time points for any planned study assessments must be 
documented and approved by the relevant study team member and then archived in the 
Sponsor/designee and study center study files, but will not constitute a protocol amendment.  The 
IRB/IEC will be informed of any safety issues that require alteration of the safety monitoring 
scheme or amendment of the ICF. 
If a subject refuses blood collection for PK analysis, this will not be considered a protocol 
violation as the PK analysis is a secondary objective. 
8.6 
Pharmacodynamics 
Venous blood samples will be collected for measurement of phospho-STAT3 assessments, and 
mRNA sequencing at the time points specified in the SoA (Section 1.3).  Details on processes for 
collection and shipment of these samples can be found in the study laboratory manual. 
8.7 
Genetics 
Blood samples for DNA isolation will be collected from subjects who have consented to 
participate in the genetic analysis component of the study.  Sample for genetic testing can be 

CONFIDENTIAL

collected at any time prior to first dose at Cycle 1 Day 1.  Participation is optional.  Subjects who 
do not wish to participate in the genetic research may still participate in the study. 
In the event of DNA extraction failure, a replacement genetic blood sample may be requested 
from the subject.  Signed informed consent will be required to obtain a replacement sample 
unless it was included in the original consent. 
See Appendix 7 for information regarding genetic research.  Details on processes for collection 
and shipment and destruction of these samples can be found in the study laboratory manual.

9.0 STATISTICAL CONSIDERATIONS 
9.1 
Statistical Hypotheses 
All statistical tests will be performed at a significance level of 0.05 with no corrections for 
multiple comparisons. 
The first primary endpoint is the proportion of subjects who achieve ≥35% SVR from baseline to 
Week 24 (splenic response).  The null hypothesis (H0) and the alternative hypothesis (HA) are: 
H0: The null hypothesis is that the proportion of subjects who achieve ≥35% SVR from 
baseline to Week 24 in each treatment arm is the same.  
HA: The alternative hypothesis is that the proportion of subjects who achieve ≥35% SVR 
from baseline to Week 24 is different by treatment arm. 
The second primary endpoint is the proportion of subjects who achieve ≥50% reduction in TSS 
from baseline to Week 24 as measured by MF-SAF v4.0. The null hypothesis (H0) and the 
alternative hypothesis (HA) are: 
H0: The null hypothesis is that the proportion of subjects who achieve ≥50% reduction in 
TSS from baseline to Week 24 as measured by MF-SAF v4.0 in each treatment arm is the 
same.  
HA: The alternative hypothesis is that the proportion of subjects who achieve 
≥50% reduction in TSS from baseline to Week 24 as measured by MF-SAF v4.0 is 
different by treatment arm. 
The efficacy of SVR and TSS, as co-primary endpoints, will be confirmed when the null 
hypotheses of SVR and TSS are rejected simultaneously.  
9.2 
Sample Size Determination 
A total of 120 randomized subjects (60 subjects in each treatment arm) is planned.  The sample 
size determination is based on literature.32, 33 
Assuming a splenic response rate of 20% in the NS-018 arm and 1% in the BAT arm, there is 
93.5% power at the final analysis to maintain a type I error rate of 5% (ie, a 2-sided significance 
level using Fisher’s exact test is 5%).  Similarly, assuming a symptom response rate of 33% in 
the NS-018 arm and 8% in the BAT arm, the power of the final analysis to maintain a Type I 
error rate of 5% is 91.0%.  Assuming that there is no correlation between SVR and TSS 
reduction, the power to reject the null hypothesis for both endpoints is 85.1%. 
 
 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
89 
9.3 
Populations for Analyses 
The intent-to-treat (ITT) population will consist of all randomized subjects. 
The modified intent-to-treat (mITT) population will consist of all randomized subjects who 
receive at least 1 dose of study treatment and have a baseline assessment and at least 
1 postbaseline efficacy assessment.  Subjects will be analyzed as randomized.  This will be the 
primary analysis population for the evaluation of efficacy. 
The safety (SAF) population will consist of all randomized subjects who receive at least 1 dose 
of study treatment.  For BAT subjects who do not receive therapy, a Cycle 1 Day 1 visit is 
required to be included in the SAF.  Subjects will be analyzed as treated.  This will be the 
primary analysis population for the evaluation of exposure and safety. 
A second safety (SAF2) population will consist of subjects randomized to BAT who complete 
BAT through 6 cycles and go on to receive at least 1 dose of NS-018.  Baseline will consist of 
the last data available prior to initiation of NS-018. 
The PK concentration population will consist of all randomized subjects who received at least 
1 dose of study treatment and have at least 1 plasma concentration value for study treatment. 
9.4 
Statistical Analyses 
A more technical and detailed description of the statistical methods will be provided in the 
statistical analysis plan (SAP).  The SAP will be developed and finalized before database lock 
and will describe the subject analysis sets to be included in the analyses, and procedures for 
accounting for missing, unused, and spurious data.  This section is a summary of the planned 
statistical analyses of the primary and secondary endpoints. 
9.4.1 
Efficacy Analyses 
The primary efficacy analyses will be performed on the mITT population (Table 6).  Efficacy 
data from the SAF2 population will be presented separately.

Efficacy Analyses 
Endpoint 
Statistical Analysis Methods 
First Primary 
The first primary endpoint of a proportion of subjects who achieve ≥35% SVR from baseline 
to Week 24 will be compared between the NS-018 group and the BAT group using 
Firth-corrected logistic regression model.  Covariates of baseline spleen volume and a history 
of prior JAK inhibitor treatment will be included.  Model-based point estimates for the 
treatment effects, 95% confidence intervals, and p-values will be calculated.  Subjects who do 
not reach Week 24 will be considered treatment nonresponders (ie, did not achieve 
≥35% SVR from baseline to Week 24).  No imputations will be made for missing data. 
Subgroup analyses may be performed by age, gender, race, stratification factors and other 
baseline characteristics. 
The primary efficacy analyses will be conducted after all subjects have completed 
assessments at Week 24 (Cycle 7 Day 1). 
Second Primary 
Similar to the analysis of the first primary endpoint, the second primary endpoint of 
proportion of subjects who achieve ≥50% reduction in TSS from baseline to Week 24 as 
measured by MF-SAF v4.0 will be compared between the NS-018 group and the BAT group 
using Firth-corrected logistic regression model.  Covariates of baseline spleen volume and a 
history of prior JAK inhibitor treatment will be included. 
Secondary 
Similar to the analysis of the primary endpoint, the secondary endpoint of proportion of 
subjects who achieve ≥35% SVR any time up to Week 24 will be compared between the 
NS-018 group and the BAT group using Firth-corrected logistic regression model.  Covariates 
of baseline spleen volume and a history of prior JAK inhibitor treatment will be included. 
Exploratory 
Will be described in the SAP finalized before database lock. 
Abbreviations: BAT=Best Available Therapy; JAK=Janus kinase; MF-SAF v4.0=Myelofibrosis Symptom 
Assessment Form version 4.0; SAP=statistical analysis plan; SVR=spleen volume reduction; TSS=total symptom 
score. 
The primary estimand is defined as: 
 Population of interest: Subjects with PMF, post-PVMF, or post-ETMF with severe 
thrombocytopenia defined by the inclusion/exclusion criteria. 
 Variables/endpoints of interest:  
 Proportion of subjects who achieve ≥35% SVR from baseline to Week 24. 
 Proportion of subjects who achieve ≥50% reduction in TSS from baseline to Week 24 
as measured by MF-SAF v4.0. 
 Intercurrent event handling strategy: 
 Death due to any cause: Subject death for any cause occurring prior to Week 24 will 
be considered as a non-response for the first and second primary endpoint definitions 
(ie, did not achieve ≥35% SVR from baseline to Week 24 and did not achieve ≥50% 
reduction in TSS from baseline to Week 24, respectively).  
 Prohibited medication: Subjects who take prohibited medication during the study will 
be analyzed by the treatment policy strategy, ie, data collected after the initiation of 
prohibited medications will be included in analysis as collected. 

CONFIDENTIAL

 Population-level summary measure:  
 Difference in proportion of subjects achieving ≥35% SVR from baseline to Week 24 
between the NS-018 group and the BAT group will be analyzed as described in 
Table 6. 
 Difference in proportion of subjects who achieve ≥50% reduction in TSS from 
baseline to Week 24 as measured by MF-SAF v4.0 between the NS-018 group and 
the BAT group will be analyzed as described in Table 6. 
The following sensitivity analysis will be planned for the primary estimand: 
 In the mITT population, subjects who experience death prior to Week 24, the last SVR will 
be imputed to Week 24 for the first primary endpoint. 
The following supplementary analysis will be planned for the primary estimand: 
 A per-protocol analysis consisting of all subjects without a major protocol violation that 
might affect the efficacy assessment (criteria will be specified prior to unblinding), following 
the same method as described for the primary estimand. 
Additional sensitivity and supplementary analysis will be explored in the SAP as appropriate. 
A similar intercurrent event handling strategy will be used for estimands related to the second 
primary endpoint of proportion of subjects who achieve ≥50% reduction in TSS from baseline to 
Week 24 as measured by MF-SAF v4.0 and the secondary endpoint of proportion of subjects 
who achieve ≥35% SVR any time up to Week 24. 
9.4.2 
Safety Analyses 
The primary safety analyses will be performed on the SAF population.  Safety data from the 
SAF2 population will be presented separately. 
Adverse Events 
Treatment-emergent AEs are defined as AEs that first occurred or worsened in severity after the 
first administration of study treatment and up to 30 days after the last administration of study 
treatment. 
Adverse events will be coded using the Medical Dictionary for Regulatory Activities.  For each 
study treatment, numbers of TEAEs and incidence rates will be tabulated by preferred term and 
system organ class.  
Treatment-emergent AEs by maximum severity, TEAEs by relationship to study treatment, 
AESIs, SAEs, TEAEs leading to death, and TEAEs leading to discontinuation of study treatment 
will be tabulated for each treatment group.

All central and local laboratory test results, vital signs measurements, ECG results, physical 
examination, spleen size (by palpation), spleen volume (by MRI) and weight will be summarized 
for each treatment group using descriptive statistics at each visit for raw numbers and change 
from baseline. 
9.4.3 
Other Analyses 
All analyses, summaries, and listings will be performed using SAS® software (version 9.4 or 
higher).  If not stated otherwise, all efficacy data will be summarized descriptively by treatment 
group and visit. 
The following descriptive statistics will be used as applicable to summarize the study data unless 
otherwise specified: 
 Continuous variables: sample size (n), mean, standard deviation, median, minimum (min), 
and maximum (max). 
 Categorical variables: frequencies and percentages. 
Individual subject data will be presented in listings.   
Pharmacokinetics, pharmacodynamics, and exploratory analyses will be described in the SAP 
finalized before database lock.  The population PK analysis and pharmacodynamic analyses will 
be presented separately from the main clinical study report.  
9.4.3.1 
Pharmacokinetics Analyses 
Blood samples for PK analysis of NS-018 will be collected at the designated study visits.  All PK 
analyses will be based on the PK population. 
Plasma concentrations of NS-018 will be summarized descriptively by time point of collection.  
Summary statistics including number of subjects, arithmetic mean, geometric mean, geometric 
coefficient of variation, coefficient of variation, standard deviation, minimum, maximum, 
median, and standard error of the mean will be presented.  Individual subject and mean plasma 
concentrations of NS-018 will be plotted versus time in linear and log-linear scale. 
Derived PK parameters will be listed and summarized using the same measures as for the plasma 
concentrations of NS-018. 
9.4.3.2 
Pharmacodynamic Analyses 
The pharmacodynamic analysis for phospho-STAT3 will be based on the pharmacodynamic 
population.  Phospho-STAT3 values at each time point and changes from baseline will be 
summarized descriptively and listed.

Sensitivity analyses of the primary endpoints to assess the impact of missing data and any 
imputation methods for secondary efficacy endpoints and partially missing dates will be 
described in the SAP. 
9.5 
Interim Analyses  
No interim analysis is planned for efficacy.  The primary efficacy analyses will be conducted 
after all subjects have completed assessments at Week 24 (Cycle 7 Day 1).  A final analysis will 
be conducted at the end of the study.  An additional analysis for futility may also be performed.  
The SAP will describe these analyses in greater detail.

Appendix 2 
Regulatory, Ethical, and Study Oversight Considerations 
Regulatory and Ethical Considerations 
 This study will be conducted in accordance with the protocol and with the following: 
 Consensus ethical principles derived from international guidelines including the 
Declaration of Helsinki and Council for International Organizations of Medical 
Sciences International Ethical Guidelines. 
 Applicable International Council for Harmonisation (ICH) Good Clinical Practice 
(GCP) Guidelines. 
 Applicable laws and regulations. 
 The protocol, protocol amendments, ICF, IB, and other relevant documents (eg, 
advertisements) must be submitted to an IRB/IEC by the Investigator and reviewed and 
approved by the IRB/IEC before the study is initiated.  
 Any amendments to the protocol will require IRB/IEC and regulatory authority approval, 
when applicable, before implementation of changes made to the study design, except for 
changes necessary to eliminate an immediate hazard to subjects.  
 The Investigator will be responsible for the following: 
 Providing written summaries of the status of the study to the IRB/IEC annually or 
more frequently in accordance with the requirements, policies, and procedures 
established by the IRB/IEC. 
 Notifying the IRB/IEC of SAEs or other significant safety findings as required by 
IRB/IEC procedures. 
 Providing oversight of the conduct of the study at the study center and adherence to 
requirements of 21 CFR, ICH guidelines, the IRB/IEC, European regulation 536/2014 
for clinical studies (if applicable), and all other applicable local regulations. 
 After reading the protocol, each Investigator will sign the protocol signature page and send a 
copy of the signed page to the Sponsor or representative (Appendix 19).  The study will not 
start at any study center at which the Investigator has not signed the protocol. 
Financial Disclosure 
Investigators and sub-Investigators will provide the Sponsor with sufficient, accurate financial 
information as requested to allow the Sponsor to submit complete and accurate financial 
certification or disclosure statements to the appropriate regulatory authorities.  Investigators are 
responsible for providing information on financial interests during the course of the study and for 
1 year after completion of the study. 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
102 
Insurance 
Sponsor will provide insurance in accordance with local guidelines and requirements as a 
minimum for the subjects in this study.  The terms of the insurance will be kept in the study files. 
Informed Consent Process 
 The Investigator or his/her representative will explain the nature of the study to the subject or 
his/her legally authorized representative and answer all questions regarding the study.  
 Subjects must be informed that their participation is voluntary.  Subjects or their legally 
authorized representative will be required to sign a statement of informed consent that meets 
the requirements of 21 CFR 50, local regulations, ICH guidelines, Health Insurance 
Portability and Accountability Act (HIPAA) requirements, where applicable, and the 
IRB/IEC or study center.  
 The medical record must include a statement that written informed consent was obtained 
before the subject was entered in the study and the date the written consent was obtained.  
The authorized person obtaining the informed consent must also sign the ICF. 
 Subjects must be re-consented to the most current version of the ICF(s) during their 
participation in the study.  
 A copy of the ICF(s) must be provided to the subject or the subject’s legally authorized 
representative.  
A subject who is rescreened will be required to sign another ICF. 
The ICF will contain a separate section that addresses the use of remaining mandatory samples 
for optional exploratory research.  The Investigator or authorized designee will explain to each 
subject the objectives of the exploratory research.  Subjects will be told that they are free to 
refuse to participate and may withdraw their consent at any time and for any reason during the 
storage period.  A separate signature will be required to document a subject’s agreement to allow 
any remaining specimens to be used for exploratory research.  Subjects who decline to 
participate in this optional research will not provide this separate signature. 
Data Protection 
 Subjects will be assigned a unique identifier by the Sponsor/designee.  Any subject records 
or datasets that are transferred to the Sponsor/designee will contain the identifier only; 
subject names or any information which would make the subject identifiable will not be 
transferred.  
 The subject must be informed that his/her personal study-related data will be used by the 
Sponsor/designee in accordance with local data protection law.  The level of disclosure must 
also be explained to the subject.  

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
103 
 The subject must be informed that his/her medical records may be examined by Clinical 
Quality Assurance auditors or other authorized personnel appointed by the Sponsor/designee, 
by appropriate IRB/IEC members, and by inspectors from regulatory authorities. 
 The ICF will incorporate (or, in some cases, be accompanied by a separate document 
incorporating) wording that complies with relevant data protection and privacy legislation. 
 The Sponsor/designee or its representative will not provide individual genotype results to 
subjects, any insurance company, any employer, their family members, general physician, or 
any other third party, unless required to do so by law. 
 Extra precautions are taken to preserve confidentiality and prevent genetic data being linked 
to the identity of the subject.  In exceptional circumstances, however, certain individuals 
might see both the genetic data and the personal identifiers of a subject.  For example, in the 
case of a medical emergency, the Sponsor/designee or representative physician or an 
Investigator might know a subject’s identity and also have access to his or her genetic data.  
Also, regulatory authorities may require access to the relevant files.

Dissemination of Clinical Study Data 
The results of the study should be reported within 1 year from the end of the clinical study.  
Irrespective of the outcome, the Sponsor will submit to the EU database a summary of the results 
of the clinical study within 1 year from the end of the clinical study.  It shall be accompanied by 
a summary written in a manner that is understandable to laypersons. 
Data Quality Assurance 
 All subject data relating to the study will be recorded on printed or eCRFs unless transmitted 
to the Sponsor or designee electronically (eg, laboratory data).  The Investigator is 
responsible for verifying that data entries are accurate and correct by physically or 
electronically signing the case report form (CRF).  
 The Investigator must maintain accurate documentation (source data) that supports the 
information entered in the eCRF.  
 The Investigator must permit study-related monitoring, audits, IRB/IEC review, and 
regulatory agency inspections and provide direct access to source data documents.  
 The Sponsor or designee is responsible for the data management of this study including 
quality checking of the data.  
 Study monitors will perform ongoing source data verification to confirm that data entered 
into the eCRF by authorized study center personnel are accurate, complete, and verifiable 
from source documents; that the safety and rights of subjects are being protected; and that the 
study is being conducted in accordance with the currently approved protocol and any other 
study agreements, ICH GCP, and all applicable regulatory requirements.  
 Records and documents, including signed ICFs, pertaining to the conduct of this study must 
be retained by the Investigator for 10 years after the last approval of a marketing application 
in an ICH region unless local regulations or institutional policies require a longer retention 
period.  No records may be destroyed during the retention period without the written 
approval of the Sponsor.  No records may be transferred to another location or party without 
written notification to the Sponsor.  
Source Documents 
The Investigator/institution should maintain adequate and accurate source documents and study 
records that include all pertinent observations on each of the study center’s subjects.  Source data 
should be attributable, legible, contemporaneous, original, accurate, and complete.  Changes to 
source data should be traceable, should not obscure the original entry, and should be explained if 
necessary (eg, via an audit trail). 
 Source documents provide evidence for the existence of the subject and substantiate the 
integrity of the data collected.  Source documents are filed at the Investigator’s study center. 
 Data reported on the CRF or entered in the eCRF that are transcribed from source documents 
must be consistent with the source documents or the discrepancies must be explained.  The 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
105 
Investigator may need to request previous medical records or transfer records, depending on 
the study.  Also, current medical records must be available. 
 Definition of what constitutes source data can be found in the Clinical Monitoring Plan. 
Study and Study Center Closure 
The Sponsor designee reserves the right to close the study center or terminate the study at any 
time for any reason at the sole discretion of the Sponsor.  Study centers will be closed upon study 
completion.  A study center is considered closed when all required documents and study supplies 
have been collected and a study center closure visit has been performed. 
The Investigator may initiate study center closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study center by the Sponsor or Investigator may include but 
are not limited to: 
 Failure of the Investigator to comply with the protocol, the requirements of the IRB/IEC or 
local health authorities, the Sponsor’s procedures, or GCP guidelines. 
 Inadequate recruitment of subjects by the Investigator. 
 Discontinuation of further study treatment development. 
 Unjustifiable risk and/or toxicity in risk-benefit analysis (decision taken by sponsor 
representative), eg, when adverse events occur, unknown to date in respect of their nature, 
severity, duration or frequency in relation to the current established safety profile (substantial 
changes in risk-benefit considerations), and therefore medical and/or ethical reasons affect 
the continued performance of the study.  
 New scientific evidence becomes available during the study that could affect the subject’s 
safety (benefit-risk analysis no longer positive), eg, new insights from other clinical trials.  
 Request of the sponsor or regulatory agency, eg, as a consequence of inspection.  
 In case of difficulties in the recruitment of the planned number of subjects in the indicated 
time (insufficient recruitment rate). 
 Withdrawal of the license to manufacture. 
Publication Policy 
The data generated by this study are confidential information of the Sponsor.  The Sponsor will 
make the results of the study publicly available.  The publication policy with respect to the 
Investigator and study center will be set forth in the Clinical Trial Agreement.

Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting 
Definition of AE 
AE Definition 
 
An AE is any untoward medical occurrence in a subject, temporally associated with the use of study 
treatment, whether or not considered related to the study treatment. 
 
NOTE: An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory 
finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. 
 
Events Meeting the AE Definition  
 
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or other safety 
assessments (eg, ECG, radiological scans, vital signs measurements), including those that worsen from 
baseline, considered clinically significant in the medical and scientific judgment of the Investigator (ie, not 
related to progression of underlying disease). 
 
Exacerbation of a chronic or intermittent preexisting condition including either an increase in frequency 
and/or intensity of the condition. 
 
New conditions detected or diagnosed after study treatment administration even though it may have been 
present before the start of the study. 
 
Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
 
Signs, symptoms, or the clinical sequelae of a suspected overdose of either study treatment or a concomitant 
medication.  Overdose per se will not be reported as an AE/SAE unless it is an intentional overdose taken 
with possible suicidal/self-harming intent.  Such overdoses should be reported regardless of sequelae. 
 
"Lack of efficacy" or "failure of expected pharmacological action" per se will not be reported as an AE or 
SAE.  Such instances will be captured in the efficacy assessments.  However, the signs, symptoms, and/or 
clinical sequelae resulting from lack of efficacy will be reported as AE or SAE if they fulfill the definition of 
an AE or SAE.   
 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
109 
Events NOT Meeting the AE Definition  
 
Any clinically significant abnormal laboratory findings or other abnormal safety assessments which are 
associated with the underlying disease, unless judged by the Investigator to be more severe than 
expected for the subject’s condition. 
 
The disease/disorder being studied or expected progression, signs, or symptoms of the disease/disorder 
being studied, unless more severe than expected for the subject’s condition. 
 
Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that leads to the 
procedure is the AE. 
 
Situations in which an untoward medical occurrence did not occur (social and/or convenience 
admission to a hospital).  Hospital visits of less than 24 hours of duration which do not result in 
hospitalization. 
 
Anticipated day-to-day fluctuations of preexisting disease(s) or condition(s) present or detected at the 
start of the study that do not worsen. 
 
Definition of SAE 
If an event is not an AE per definition above, then it cannot be an SAE even if serious conditions 
are met (eg, hospitalization for signs/symptoms of the disease under study, death due to 
progression of disease). 
An SAE is defined as any untoward medical occurrence that, at any dose: 
a) Results in death 
b) Is life-threatening 
The term ‘life-threatening’ in the definition of “serious” refers to an event in which the subject was at risk of 
death at the time of the event.  It does not refer to an event, which hypothetically might have caused death, if it 
were more severe. 
c) Requires inpatient hospitalization or prolongation of existing hospitalization 
In general, hospitalization signifies that the subject has been detained (usually involving at least an overnight 
stay) at the hospital or emergency ward for observation and/or treatment that would not have been appropriate in 
the physician’s office or outpatient setting.  Complications that occur during hospitalization are AEs.  If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is serious.  When in doubt as 
to whether “hospitalization” occurred or was necessary, the AE should be considered serious. 
Hospitalization for elective treatment of a preexisting condition that did not worsen from baseline is not 
considered an AE. 
d) Results in persistent disability/incapacity 
 
The term disability means a substantial disruption of a person’s ability to conduct normal life functions. 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
110 
 
This definition is not intended to include experiences of relatively minor medical significance such as 
uncomplicated headache, nausea, vomiting, diarrhea, influenza, and accidental trauma (eg, sprained ankle) 
which may interfere with or prevent everyday life functions but do not constitute a substantial disruption. 
e) Is a congenital anomaly/birth defect 
f) 
Other situations: 
 
Medical or scientific judgment should be exercised in deciding whether SAE reporting is appropriate in other 
situations such as important medical events that may not be immediately life-threatening or result in death or 
hospitalization but may jeopardize the subject or may require medical or surgical intervention to prevent one 
of the other outcomes listed in the above definition.  These events should usually be considered serious. 
Examples of such events include invasive or malignant cancers, intensive treatment in an emergency room or 
at home for allergic bronchospasm, blood dyscrasias, or convulsions that do not result in hospitalization, or 
development of drug dependency or drug abuse.

111 
Recording and Follow-up of AE and/or SAE 
AE and SAE Recording 
 
When an AE/SAE occurs, it is the responsibility of the Investigator to review all documentation (eg, hospital 
progress notes, laboratory reports, and diagnostics reports) related to the event. 
 
The Investigator will then record all relevant AE/SAE information in the CRF.  Each event must be recorded 
separately. 
 
It is not acceptable for the Investigator to send photocopies of the subject’s medical records to 
Sponsor/designee in lieu of completion of the CRF page. 
 
There may be instances when copies of medical records for certain cases are requested by Sponsor/designee.  
In this case, all subject identifiers, with the exception of the subject number, will be redacted on the copies of 
the medical records before submission. 
 
The Investigator will attempt to establish a diagnosis of the event based on signs, symptoms, and/or other 
clinical information.  Whenever possible, the diagnosis (not the individual signs/symptoms) will be 
documented as the AE/SAE. 
Assessment of Intensity 
The Investigator will make an assessment of intensity for each AE and SAE reported during the study according to 
Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 
(https://ctep.cancer.gov/protocoldevelopment/electronic_applications/docs/CTCAE_v5_Quick_Reference_5x7.pdf) 
or higher grading scale.  For AEs not covered by National Cancer Institute (NCI) CTCAE, the severity will be 
characterized as mild, moderate, severe, life-threatening, or fatal according to the following definitions: 
 
Grade 1: Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not 
indicated.  
 
Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental 
Activities of Daily Living (ADL)*.  
 
Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization or prolongation 
of hospitalization indicated; disabling; limiting self-care ADL**.  
 
Grade 4: Life-threatening consequences; urgent intervention indicated.  
 
Grade 5: Death related to AE. 
A semi-colon indicates ‘or’ within the description of the grade.  
A single dash (-) indicates a grade is not available.  
Activities of Daily Living (ADL)  
*Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the telephone, managing 
money, etc. 
**Self-care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, taking medications, and 
not bedridden.

Assessment of Causality 
 
The Investigator is obligated to assess the relationship between study treatment and each occurrence of each 
AE/SAE.  The AE must be characterized as unrelated, unlikely to be related, possibly related, probably 
related, or definitely related. 
o 
“Definitely related” conveys the adverse event has a timely relationship to administration of study 
treatment and there is no apparent, potential alternate etiology. 
o 
“Probably related” conveys that there are facts, evidence, and/or arguments to suggest a causal 
relationship, rather than a relationship cannot be ruled out. 
o 
“Possibly related” suggests that the association of the AE with the study treatment is unknown; 
however, the AE is not reasonably supported by other conditions. 
o 
“Unlikely to be related” suggests that only a remote connection exists between the study treatment 
and the AE.  Other conditions, including chronic illness, progression or expression of the disease 
state or reaction to concomitant therapy, appear to explain the reported AE. 
o 
“Unrelated” is used if there is not a reasonable possibility that the study treatment caused the AE.  
 
The Investigator will use clinical judgment to determine the relationship. 
 
Alternative causes, such as underlying disease(s), concomitant therapy, and other risk factors, as well as the 
temporal relationship of the event to study treatment administration will be considered and investigated. 
 
The Investigator will also consult the IB and/or Product Information, for marketed products, in his/her 
assessment. 
 
For each AE/SAE, the Investigator must document in the medical notes that he/she has reviewed the AE/SAE 
and has provided an assessment of causality. 
 
There may be situations in which an SAE has occurred and the Investigator has minimal information to 
include in the initial report to the Sponsor/designee.  However, it is very important that the Investigator always 
make an assessment of causality for every event before the initial transmission of the SAE data to the 
Sponsor/designee. 
 
The Investigator may change his/her opinion of causality in light of follow-up information and send a SAE 
follow-up report with the updated causality assessment. 
 
The causality assessment is one of the criteria used when determining regulatory reporting requirements. 
o 
Events deemed “Unlikely to be related” and “Unrelated” will not be considered a SUSAR for 
regulatory reporting purposes.

Follow-up of AEs and SAEs 
 
The Investigator is obligated to perform or arrange for the conduct of supplemental measurements and/or 
evaluations as medically indicated or as requested by Sponsor/designee to elucidate the nature and/or causality 
of the AE or SAE as fully as possible.  This may include additional laboratory tests or investigations, 
histopathological examinations, or consultation with other health care professionals. 
 
New or updated information will be recorded in the originally completed CRF. 
 
The Investigator will submit any updated SAE data to the Sponsor/designee within 24 hours of receipt of the 
information. 
 
Reporting of SAEs 
SAE Reporting to Sponsor/designee via an Electronic Data Collection Tool 
 
The primary mechanism for reporting an SAE to Sponsor/designee will be the electronic data collection tool. 
 
If the electronic system is unavailable for more than 24 hours, then the study center will use the paper SAE 
data collection tool (see next section). 
 
The study center will enter the SAE data into the electronic system as soon as it becomes available. 
 
After the study is completed at a given study center, the electronic data collection tool will be taken off-line to 
prevent the entry of new data or changes to existing data. 
 
If a study center receives a report of a new SAE from a subject or receives updated data on a previously 
reported SAE after the electronic data collection tool has been taken off-line, then the study center can report 
this information on a paper SAE form (see next section) or to the Medical Monitor/SAE coordinator by 
telephone. 
 
Contacts for SAE reporting can be found in the Investigator Study Binder 
 
SAE Reporting to Sponsor/designee via Paper CRF 
 
E-mail transmission of the SAE paper CRF is the preferred method to transmit this information to 
Sponsor/designee with Facsimile transmission as back-up method. 
 
In rare circumstances and in the absence of e-mail/facsimile equipment, notification by telephone is acceptable 
with a copy of the SAE data collection tool. 
 
Initial notification via telephone does not replace the need for the Investigator to complete and sign the SAE 
CRF pages within the designated reporting time frames. 
 
Contacts for SAE reporting can be found in the Investigator Study Binder.  Submission of paper CRF pages, 
in the event electronic data collection tool is unavailable, should be completed and submitted via e-mail to 
Safety-Inbox.Biotech@IQVIA.com or faxed to +1-919-313-1412.

Contraceptive Guidance and Collection of Pregnancy 
Information 
Definitions: 
Woman of Childbearing Potential (WOCBP) 
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile (see below). 
Women in the following categories are not considered WOCBP 
1. Premenarchal 
2. Premenopausal female with one of the following: 
a. Documented hysterectomy. 
b. Documented bilateral salpingectomy. 
c. Documented bilateral oophorectomy. 
Note: Documentation can come from the study center personnel’s: review of the subject’s 
medical records, medical examination, or medical history interview. 
3. Postmenopausal female: 
a. A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause.  A high follicle-stimulating hormone (FSH) level in the postmenopausal range 
may be used to confirm a postmenopausal state in women not using hormonal contraception 
or hormonal replacement therapy (HRT).  However, in the absence of 12 months of 
amenorrhea, a single FSH measurement is insufficient.  
b. Females on HRT and whose menopausal status is in doubt will be required to use highly 
effective contraception methods if they wish to continue their HRT during the study.  
Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status 
before study enrollment. 
Contraception Guidance 
Male subjects 
 Male subjects must refrain from donating sperm for the duration of the study and for 180 
days after study completion or the last dose of study treatment. 
 Male subjects with partners who are WOCBP, pregnant or breastfeeding must agree to 
remain abstinent from penile-vaginal intercourse throughout the study treatment period until 
180 days from last study treatment.  
 Be abstinent from penile-vaginal intercourse as their usual and preferred lifestyle (abstinent 
on a long term and persistent basis) and agree to remain abstinent. 
 Use a male condom plus partner use of an additional contraceptive method when having 
penile-vaginal intercourse with a woman of childbearing potential who is not currently 
pregnant. 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
118 
The following are not acceptable methods of contraception: 
 Periodic abstinence (calendar, symptom-thermal, post-ovulation methods), withdrawal 
(coitus interruptus), spermicides only, and lactational amenorrhea method (LAM). 
 Male condom with cap, diaphragm or sponge with spermicide. 
 Male and female condom cannot be used together. 
Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-
vaginal intercourse or use a male condom during each episode of penile penetration. 
Female subjects 
Female subjects of childbearing potential are eligible to participate if they agree to use 2 highly 
effective methods of contraception consistently and correctly as described in the table below.  
Female subjects must use the permitted contraception during the study and for 180 days after the 
last dose of NS-018 or for the duration required by product information of the comparator drug.  
Contraception requirements in the product information of a comparator therapy must be 
followed. 
Highly Effective Contraceptive Methods 
Highly Effective Methods That Are User Independent a  
 
Intrauterine device. 
 
Intrauterine hormone-releasing system (Italy only). 
 
Bilateral tubal occlusion. 
Vasectomized partner  
A vasectomized partner is a highly effective birth control method provided that the partner is the sole male sexual 
partner of the WOCBP and the absence of sperm has been confirmed.  If not, an additional highly effective method 
of contraception should be used.   
Sexual abstinence  
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual 
intercourse during the entire period of risk associated with the study treatment.  The reliability of sexual abstinence 
needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the subject.   
NOTES:  
a Failure rate of less than 1% per year.  Typical use failure rates may differ from those when used consistently and 
correctly.  Use should be consistent with local regulations regarding the use of contraceptive methods for 
subjects participating in clinical studies.  
Two highly effective methods of contraception should be utilized during the treatment period and for 180 days (for 
females) and 180 days (for male subjects with partners who are women of childbearing potential [WOCBP], 
pregnant or breast feeding), corresponding to time needed to eliminate study treatments with genotoxic potential 
after the last dose of study treatment.  Hormonal contraception methods are not allowed to be used.

Pregnancy Testing: 
 WOCBP should only be included after a confirmed menstrual period and a negative highly 
sensitive serum pregnancy test at times specified in the SoA (Section 1.3). 
Collection of Pregnancy Information 
Male subjects with partners who become pregnant  
 The Investigator will attempt to collect pregnancy information on any male subject’s female 
partner who becomes pregnant while the male subject is in this study.  This applies only to 
male subjects who receive study treatment. 
 After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the Investigator will record pregnancy information on the appropriate form and 
submit it to the Sponsor/designee within 24 hours of learning of the partner’s pregnancy.  
The female partner will also be followed to determine the outcome of the pregnancy.  
Information on the status of the mother and child will be forwarded to the Sponsor/designee.  
Any termination of the pregnancy will be reported regardless of fetal status (presence or 
absence of anomalies) or indication for the procedure.  
Female subjects who become pregnant  
 The Investigator will collect pregnancy information on any female subject who becomes 
pregnant while participating in this study.  Information will be recorded on the appropriate 
form and submitted to the Sponsor/designee within 24 hours of learning of a subject’s 
pregnancy.  The subject will be followed to determine the outcome of the pregnancy.  The 
Investigator will collect follow-up information on the subject and the neonate and the 
information will be forwarded to the Sponsor.  
 The Investigator must follow the pregnancy either to term or termination and will collect data 
on both maternal and fetal outcomes until final outcome (ie, normal, abnormal including 
abortion).  Pregnancy alone is not considered an AE. 
 While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy will be reported as an AE or SAE.  A spontaneous 
abortion is always considered to be an SAE and will be reported as such. 
 Any post-study pregnancy related SAE considered reasonably related to the study treatment 
by the Investigator will be reported to the Sponsor/designee as described in Section 8.3.4.  
While the Investigator is not obligated to actively seek this information in former subjects, he 
or she may learn of an SAE through spontaneous reporting.  
 Any female subject who becomes pregnant while participating in the study will discontinue 
study treatment or be withdrawn from the study.

Genetics 
Use/Analysis of DNA 
 Genetic variation may impact a subject’s response to study treatment, susceptibility to, and 
severity and progression of disease.  Variable response to study treatment may be due to 
genetic determinants that impact drug absorption, distribution, metabolism, and excretion; 
mechanism of action of the drug; disease etiology; and/or molecular subtype of the disease 
being treated. Therefore, where local regulations and IRB/IEC allow, a blood sample will be 
collected for DNA analysis from consenting subjects. 
 DNA samples will be used for genetic mutation profiling.  
 The results of genetic mutation profiling may be reported in the clinical study report. 
 The Sponsor will store the DNA samples in a secure storage space with adequate measures to 
protect confidentiality. 
 The samples will be discarded once this study is completed.

Dynamic International Prognostic Scoring System 
The DIPSS includes the same 5 prognostic factors as the IPSS but ascribes greater weight to low 
hemoglobin (2 points instead of 1) while the other risk factors are counted as 1; risk scoring is 
modified accordingly, and corresponding median survival estimates for low-, intermediate 1-, 
intermediate 2-, and high-risk diseases range from not reached to 1.5 years.

The 5 adverse prognostic factors identified as predictors of shortened survival are: 
 Age >65 years 
 Constitutional symptoms 
 Hemoglobin <10 g/dL 
 White blood cell count >25 × 109/L 
 Peripheral blood blasts ≥1% 
Subjects are assigned into one of 4 risk categories based on the number of risk factors present.

Recommendations for assessing treatment-induced cytogenic and molecular changes 
Cytogenetic remission 
At least 10 metaphases must be analyzed for cytogenetic response evaluation 
and requires confirmation by repeat testing within 6 months window. 
 
CR: eradication of a pre-existing abnormality 
PR: ≥50% reduction in abnormal metaphases (partial response applies only 
to subjects with at least 10 abnormal metaphases at baseline) 
Molecular remission 
Molecular response evaluation must be analyzed in peripheral blood 
granulocytes and requires confirmation by repeat testing within 6 months 
window. 
 
CR: Eradication of a pre-existing abnormality 
PR: ≥50% decrease in allele burden (partial response applies only to subjects 
with at least 20% mutant allele burden at baseline) 
Cytogenetic/molecular relapse 
Re-emergence of a pre-existing cytogenetic or molecular abnormality that is 
confirmed by repeat testing 
Abbreviations: EMH=extramedullary hematopoiesis (no evidence of EMH implies the absence of pathology- or 
imaging study-proven nonhepatosplenic EMH); LCM=left costal margin; MF=myelofibrosis; UNL=upper 
normal limit. 
* Baseline and post-treatment bone marrow slides are to be interpreted locally at one sitting preferably by the same 
assessor.  Cytogenetic and molecular responses are not required for CR assignment. 
† Grading of MF is according to the European classification (Thiele et al.  European consensus on grading bone 
marrow fibrosis and assessment of cellularity.  Haematologica 2005;90:1128).  It is underscored that the 
consensus definition of a CR bone marrow is to be used only in those subjects in which all other criteria are met, 
including resolution of leukoerythroblastosis.  It should also be noted that it was a particularly difficult task for 
the working group to reach a consensus regarding what represents a complete histologic remission. 
‡ Immature myeloid cells constitute blasts + promyelocytes + myelocytes + metamyelocytes + nucleated red blood 
cells.  In splenectomized subjects, 5% immature myeloid cells is allowed. 
§ See above for definitions of anemia response, spleen response, and progressive disease.  Increase in severity of 
anemia constitutes the occurrence of new transfusion dependency or a ≥20 g/L decrease in hemoglobin level 
from pretreatment baseline that lasts for at least 12 weeks.  Increase in severity of thrombocytopenia or 
neutropenia is defined as a 2-grade decline, from pretreatment baseline, in platelet count or absolute neutrophil 
count, according to the CTCAE version 4.0.  In addition, assignment to CI requires a minimum platelet count of 
≥25,000 × 109/L and absolute neutrophil count of ≥0.5 × 109/L. 
|| Applicable only to subjects with baseline hemoglobin of <100 g/L.  In subjects not meeting the strict criteria for 
transfusion dependency at the time of study enrolment (see as follows), but have received transfusions within the 
previous month, the pretransfusion hemoglobin level should be used as the baseline. 

CONFIDENTIAL 
Final Protocol NS-018-201 - Protocol V3.0 
 
132 
{ Transfusion dependency before study enrollment is defined as transfusions of at least 6 units of packed red blood 
cells (PRBC), in the 12 weeks prior to study enrollment, for a hemoglobin level of <85 g/L, in the absence of 
bleeding or treatment-induced anemia.  In addition, the most recent transfusion episode must have occurred in the 
28 days prior to study enrollment.  Response in transfusion-dependent subjects requires absence of any PRBC 
transfusions during any consecutive “rolling” 12-week interval during the treatment phase, capped by a 
hemoglobin level of ≥85 g/L. 
# In splenectomized subjects, palpable hepatomegaly is substituted with the same measurement strategy. 
** Spleen or liver responses must be confirmed by imaging studies where a ≥35% reduction in spleen volume, as 
assessed by MRI or CT, is required.  Furthermore, a ≥35% volume reduction in the spleen or liver, by MRI or 
CT, constitutes a response regardless of what is reported with physical examination. 
†† Symptoms are evaluated by the MPN-SAF TSS.  The MPN-SAF TSS is assessed by the subjects 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. 
‡‡ Progressive disease assignment for splenomegaly requires confirmation by MRI or computed tomography 
showing a ≥25% increase in spleen volume from baseline.  Baseline values for both physical examination and 
imaging studies refer to pretreatment baseline and not to post-treatment measurements.

f 
Safety laboratory assessments will be performed on Cycle 1 Days 1, 8, 15, and 22, Cycle 2 through Cycle 6 on Days 1 and 15, and Day 1 of each cycle thereafter at minimum.  
For subjects who transition to NS-018, safety laboratory assessments will be performed on Day 1 and Day 15 of each cycle for the first 6 cycles after transitioning to NS-018 
(including the additional visits on Day 8 and Day 22 of the first cycle after transitioning).  Hematology includes erythrocytes, MCV, MCH, neutrophils, eosinophils, basophils, 
lymphocytes, monocytes, platelets, leukocytes, hemoglobin, and hematocrit.  Serum chemistry includes BUN, LDH, creatinine, uric acid, total protein, albumin, glucose, direct 
bilirubin for screening, total bilirubin (for safety assessment), magnesium, ALP, AST, ALT, chloride, sodium, potassium, amylase, and lipase.  Urinalysis includes pH, protein, 
glucose, ketone, bilirubin, blood, and nitrite.  Assessments on Day 8 and Day 22 of Cycle 1 for subjects randomized to NS-018 or Cycle 1 after transitioning to NS-018 in 
subjects who transition to NS-018 will be performed at the institutional local laboratory.  All other safety laboratory assessments will be performed at the central laboratory.  
Additional local laboratory assessments may be performed per Investigator’s discretion to monitor safety and document AEs as per local standards of care.

h 
Within 28 days prior to the first dose of study drug.  However, bone marrow assessment performed within 6 months prior to the first dose can be used as baseline. 
i 
 During the screening period, subjects will complete the MF-SAF v4.0 assessment daily. The first 7 consecutive days of diary data will be used for eligibility assessments. 
Subjects will complete the MF-SAF daily  from Day −7 of Cycle 1 Day 1 to the end of Cycle 6 (Day 168) and the last 7 days in each cycle thereafter until the end of Cycle 12 
(Day 336) for efficacy assessment. 
j 
The PROMIS questionnaire must be completed daily during the screening period and the last 7 days of each cycle until the end of Cycle 12 (Day 336).  This assessment will be 
performed for all subjects including subjects transitioning from BAT to NS-018. 
k 
If not done within the previous 8 weeks. 
l 
Within 14 days after last dose of study treatment or within 14 days after withdrawal from the study. 
m Randomization can be done within Day −4 so that the subject can start study treatment on the morning of Day 1. 
n 
In the BAT treatment arm (control group), after subjects have completed treatment with BAT at the end of Cycle 6, subjects will discontinue BAT and transition to NS-018 at 
Cycle 7 Day 1.  During this transition period, subjects treated with ruxolitinib will be required to taper off this treatment before initiation of NS-018.  The dose of ruxolitinib 
should be decreased every 7 days by up to 50% until the smallest dose possible has been given for a minimum duration for the total tapering period of 14 days.  Ruxolitinib 
should then be stopped 1 day before starting NS-018.  Subjects who are taking 5 mg QD of ruxolitinib are already on the lowest dose possible; therefore, tapering is not 
applicable in this case.  If recurrence of MF-related symptoms (upon discontinuation of ruxolitinib therapy) is noted, it is strongly suggested that therapy with ruxolitinib be 
restarted.  If restart is not possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg QD) is recommended.  Subjects administered with treatment other than 
ruxolitinib will undergo a minimum washout period of 1 week (7 days) prior to start of NS-018 treatment.

NOTE: At Cycle 1 Day 1, before the subject starts study treatment, all eligibility criteria including the subject’s COVID-19 status should be reviewed and confirmed.   
NOTE: Verification of COVID-19 status is based on the World Health Organization diagnostic criteria (Public health surveillance for COVID-19.  Interim guidance, 
07 August 2020).  If a subject presents with clinical signs and symptoms consistent with COVID-19 infection, the Investigator should request a test where possible and this 
should be recorded in the AE field of the eCRF.

a 
Including concomitant medications within 28 days prior to study treatment administration, blood products transfused within 3 months prior to study treatment administration, 
and concurrent baseline conditions. 
b 
Full physical examination including weight and spleen size by clinical assessment (palpation).  At screening, spleen size (palpation) measurement must be done on the same 
day the spleen volume is measured by MRI. 
c 
Directed physical examination including weight and spleen size by palpation.  A skin examination will also be conducted as part of the physical examination.  
d 
Assess spleen volume within 14 days prior to the first dose of the study treatment. 
e 
Predose; may be obtained within 24 hours prior to study treatment administration.  AEs on Cycle 1 Day 1 will also be collected postdose. 
f 
Subjects transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have safety laboratory assessments performed on Day 1 and 15 of each cycle for 6 cycles. Safety 
laboratory assessments will continue on Day 1 of the following cycles until the end of the study.  Hematology includes erythrocytes, MCV, MCH, neutrophils, eosinophils, 
basophils, lymphocytes, monocytes, platelets, leukocytes, hemoglobin, and hematocrit.  Serum chemistry includes BUN, LDH, creatinine, uric acid, total protein, albumin, 
glucose, direct bilirubin (for screening)  total bilirubin (safety assessment), magnesium, ALP, AST, ALT, chloride, sodium, potassium, amylase, and lipase.  Urinalysis includes 
pH, protein, glucose, ketone, bilirubin, blood, and nitrite. Note: Additional local laboratory assessments may be performed per Investigator’s discretion to monitor safety and 
document AEs as per local standards of care. 
g 
For eligibility determination; median QTcF must be ≤480 msec.  For screening, Cycles 1 and 2, triplicate central reading, and then from Cycle 4 onwards, single central 
reading.  ECGs Cycle 1 Day 1: Predose (3 time points within 1 hour) and 1, 2, 4, 6, 8 (±10 minutes) hours after administration of NS-018, Cycle 1 Day 15: 2 (±10 minutes) 
hours after administration of NS-018, Cycle 2 Day 1: Predose (within 1 hour) and 1, 2, 4 (±10 minutes) hours after administration of NS-018, Cycle 3 Day 1 predose (within 1 
hour) and 1, 2, and 4 (±10 minutes) hours after administration of NS-018, and Cycle 4 Day 1 and thereafter every 3 cycles: 2 (±10 minutes) hours after administration of NS-
018.  NOTE: An additional single ECG will be done at Cycle 3 and Cycle 9, Day 1 predose (within 1 hour) and 1, 2, and 4 (±10 minutes) hours after administration of NS-018.   
h 
Within 28 days prior to the first dose of study drug.  However, bone marrow assessment performed within 6 months prior to the first dose can be used as baseline. 
i 
During the screening period, subjects will complete the MF-SAF v4.0 assessment daily. The first 7 consecutive days of diary data will be used  for eligibility assessments. 
Subjects will complete the MF-SAF daily  from Day −7 of Cycle 1 Day 1 to the end of Cycle 6 (Day 168) and the last 7 days in each cycle thereafter until the end of Cycle 12 
(Day 336) for efficacy assessment. 
j 
The PROMIS questionnaire must be completed daily during the screening period and the last 7 days of each cycle until the end of Cycle 12 (Day 336).  This assessment will be 
performed for all subjects including subjects transitioning from BAT to NS-018. 
k 
If not done within the previous 8 weeks. 
l 
Within 14 days after last dose of study treatment or within 14 days after withdrawal from the study. 
m Randomization can be done within Day −4 so that the subject can start study treatment on the morning of Day 1. 
n 
In the BAT treatment arm (control group), after subjects have completed treatment with BAT at the end of Cycle 6, subjects will discontinue BAT and transition to NS-018 at 
Cycle 7 Day 1.  During this transition period, subjects treated with ruxolitinib will be required to taper off this treatment before initiation of NS-018.  The dose of ruxolitinib 
should be decreased every 7 days by up to 50% until the smallest dose possible has been given for a minimum duration for the total tapering period of 14 days.  Ruxolitinib 
should then be stopped 1 day before starting NS-018.  Subjects who are taking 5 mg QD of ruxolitinib are already on the lowest dose possible; therefore, tapering is not 
applicable in this case.  If recurrence of MF-related symptoms (upon discontinuation of ruxolitinib therapy) is noted, it is strongly suggested that therapy with ruxolitinib be 
restarted.  If restart is not possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg QD) is recommended.  Subjects administered with treatment other than 
ruxolitinib will undergo a minimum washout period of 1 week (7 days) prior to start of NS-018 treatment. 
o 
Subjects who discontinue study treatment or withdraw from the study will be asked to complete the end of study procedures within 14 days after the last dose.  If the end of 
study procedures occur at a regular scheduled visit, these procedures may be performed at that time.

P 
Follow-up phone call will be done 30 (±3) days after the completion of end of study procedures. 
q 
For WOCBP only, a negative serum pregnancy test will be required within 7 days prior to dosing on Cycle 1 Day 1, and a negative urine and/or serum pregnancy test will be 
required within 7 days prior to dosing on Day 1 of each cycle (local laboratory).  Of note to sites, if the urine test is the choice and is positive or cannot be confirmed as 
negative, a serum pregnancy test must be completed to confirm pregnancy result.  
WOCBP will have pregnancy tests done monthly for early detection of pregnancy and discontinuation of study drugs.

NOTE: At Cycle 1 Day 1, before the subject starts study treatment, all eligibility criteria including the subject’s COVID-19 status should be reviewed and confirmed.   
NOTE: Verification of COVID-19 status is based on the World Health Organization diagnostic criteria (Public health surveillance for COVID-19.  Interim guidance; 
07 August 2020).  If a subject presents with clinical signs and symptoms consistent with COVID-19 infection, the Investigator should request a test where possible and this 
should be recorded in the AE field of the eCRF. 
NOTE: Monthly pregnancy tests should be performed for women of childbearing potential.  The serum pregnancy test should not be older than 72 hours before taking the first dose 
and can be done locally.  The subsequent monthly serum pregnancy tests should be done at Day 1 of each Cycle until the end of the study. 
NOTE: Subjects transitioning from BAT to NS-018 must be monitored as closely as subjects who are initially randomized to NS-018 with physical examination, vital signs, safety 
laboratory assessments and 12-lead ECG, etc., for the first cycles after transition to the NS-018 following the SoA from Cycle 1 Day 1. 
a 
Including concomitant medications within 28 days prior to study treatment administration, blood products transfused within 3 months prior to study treatment administration, 
and concurrent baseline conditions. 
b 
Full physical examination including weight and spleen size by clinical assessment (palpation).  At screening, spleen size (palpation) measurement must be done on the same 
day the spleen volume is measured by MRI. If the same day measurement is not feasible, the measurement should be assessed within 14 days prior to the first dose of the study 
treatment. 
c 
Directed physical examination including weight and spleen size by palpation. 
d 
Assess spleen volume within 14 days prior to the first dose of the study treatment.

f 
Subjects transitioning from BAT to NS-018 before or at Cycle 7 Day 1 will have safety laboratory assessments performed on Day 1 and 15 of each cycle for 6 cycles. Safety 
laboratory assessments will continue on Day 1 of the following cycles until the end of the study.  Hematology includes erythrocytes, MCV, MCH, neutrophils, eosinophils, 
basophils, lymphocytes, monocytes, platelets, leukocytes, hemoglobin, and hematocrit.  Serum chemistry includes BUN, LDH, creatinine, uric acid, total protein, albumin, 
glucose, direct bilirubin for screening, total bilirubin (for safety measurement), magnesium, ALP, AST, ALT, chloride, sodium, potassium, amylase, and lipase.  Urinalysis 
includes pH, protein, glucose, ketone, bilirubin, blood, and nitrite. Additional local laboratory assessments may be performed per Investigator’s discretion to monitor safety and 
document AEs as per local standards of care. 
g 
For eligibility determination; median QTcF must be ≤480 msec.  For screening, Cycles 1 and 2, triplicate central reading, and then from Cycle 4 onwards, single central 
reading.  ECGs for Cycle 1 Day 1: Predose (3 time points within 1 hour) and 1, 2, 4, 6, 8 (±10 minutes) hours after administration of NS-018, Cycle 1 Day 15: 2 (±10 minutes) 
hours after administration of NS-018, Cycle 2 Day 1: Predose (within 1 hour) and 1, 2, 4 (±10 minutes) hours after administration of NS-018, and Cycle 4 Day 1 and thereafter 
every 3 cycles: 2 (±10 min) hours after administration of NS-018.  
h 
Within 28 days prior to the first dose of study drug.  However, bone marrow assessment performed within 6 months prior to the first dose can be used as baseline. 
i 
During the screening period, subjects will complete the MF-SAF v4.0 assessment daily. The first 7 consecutive days of diary data will be used for eligibility assessments. 
Subjects will complete the MF-SAF daily from Day −7 of Cycle 1 Day 1 to the end of Cycle 6 (Day 168) and the last 7 days in each cycle thereafter until the end of Cycle 12 
(Day 336) for efficacy assessment. 
j 
The PROMIS questionnaire must be completed daily during the screening period and the last 7 days of each cycle until the end of Cycle 12 (Day 336).  This assessment will be 
performed for all subjects including subjects transitioning from BAT to NS-018. 
k 
If not done within the previous 8 weeks. 
l 
Within 14 days after last dose of study treatment or within 14 days after withdrawal from the study. 
m Randomization can be done within Day −4 so that the subject can start study treatment on the morning of Day 1. 
n 
In the BAT treatment arm (control group), after subjects have completed treatment with BAT at the end of Cycle 6, subjects will discontinue BAT and transition to NS-018 at 
Cycle 7 Day 1.  During this transition period, subjects treated with ruxolitinib will be required to taper off this treatment before initiation of NS-018.  The dose of ruxolitinib 
should be decreased every 7 days by up to 50% until the smallest dose possible has been given for a minimum duration for the total tapering period of 14 days.  Ruxolitinib 
should then be stopped 1 day before starting NS-018.  Subjects who are taking 5 mg QD of ruxolitinib are already on the lowest dose possible; therefore, tapering is not 
applicable in this case.  If recurrence of MF-related symptoms (upon discontinuation of ruxolitinib therapy) is noted, it is strongly suggested that therapy with ruxolitinib be 
restarted.  If restart is not possible, then prompt therapy with corticosteroids (eg, prednisone 60 mg QD) is recommended.  Subjects administered with treatment other than 
ruxolitinib will undergo a minimum washout period of 1 week (7 days) prior to start of NS-018 treatment. 
o 
Subjects who discontinue study treatment or withdraw from the study will be asked to complete the end of study procedures within 14 days after the last dose.  If the end of 
study procedures occur at a regular scheduled visit, these procedures may be performed at that time. 
P 
Follow-up phone call will be done 30 (±3) days after the completion of end of study procedures. 
q  For WOCBP only, a negative serum pregnancy test will be required within 7 days prior to dosing on Cycle 1 Day 1, and a negative urine and/or serum pregnancy test will be 
required within 7 days prior to dosing on Day 1 of each cycle (local lab).  Of note to sites, if the urine test is the choice and is positive or cannot be confirmed as negative, a 
serum pregnancy test must be completed to confirm pregnancy result.  WOCBP will have pregnancy tests done monthly for early detection of pregnancy and discontinuation of 
study drugs.
