Objectives 
Primary: 
• 
Evaluate the safety and tolerability of ND-L02-s0201, administered at 2 dose levels, once 
every 2 weeks (Q2W) over 24 weeks, versus placebo, in conjunction with standard of care 
(SOC) 
Secondary: 
• 
Evaluate the biological activity of ND-L02-s0201 as measured by spirometry over 24 weeks 
• 
Evaluate changes of interstitial lung abnormalities (ILA) as measured by high-resolution 
computed tomography (HRCT)  
• 
Evaluate single-dose pharmacokinetic (PK) endpoints over 24 weeks in a subset of subjects 
• 
Evaluate trough levels for accumulation over time and identify when steady state conditions 
are achieved 
Methodology 
This is a Phase 2, double-blind, placebo-controlled, randomized, multicenter, international study of 
2 doses of ND-L02-s0201 for Injection to evaluate safety, tolerability, biological activity, and PK in 
subjects with a diagnosis of IPF with forced vital capacity (FVC) ≥ 45% of predicted and diffusion 
capacity of the lung for carbon monoxide (DLCO) ≥ 30% of predicted and who meet all inclusion 
criteria and do not meet any exclusion criteria.  
Two dose levels of ND-L02-s0201 will be evaluated: a low dose (45 mg) and a high dose (90 mg). 
Subjects will be randomly assigned to receive ND-L02-s0201 for Injection or placebo Q2W over a 
24-week treatment period. Approximately 120 eligible subjects will be randomized 1:1:1 to 1 of 
3 treatment arms: ND-L02-s0201 for Injection high dose (90 mg), ND-L02-s0201 for Injection low 
dose (45 mg), or placebo.

For the purposes of this trial, SOC is defined as administration of either nintedanib or pirfenidone, 
though not both. Alternatively, eligible subjects do not need to be on either medication. For subjects 
in Germany only (due to country specific medical practice and guidelines), subjects do not need to be 
on either medication, provided they have failed or not tolerated nintedanib and/or pirfenidone. 
Subjects receiving SOC at the time of enrollment in the study will be stratified across the 3 treatment 
arms via the interactive web response system (IWRS). As there is no minimum number of subjects for 
a given SOC stratum, balance in strata across the 3 treatment arms is required.  
Discontinuation of either nintedanib or pirfenidone must have occurred at least 12 weeks before 
Visit 1a. If the subject has been taking either pirfenidone or nintedanib before Visit 1a, the same 
medication should be continued during the subject’s participation in this trial. However, dose 
adjustment or discontinuation of SOC in accordance with the prescribing information is permitted if 
clinically indicated. If the subject is not taking either pirfenidone or nintedanib at Visit 1a, neither 
medication may be taken through Week 24 (Visit 14) or Early Termination (ET). No other 
investigational therapy for IPF is allowed within 8 weeks or 5 half-lives (whichever is longer) before 
Visit 1a. 
Pharmacokinetics: 
 
 
 
 
  
 
Number of Subjects (planned) 
Approximately 120 subjects will be enrolled into the study, with approximately 40 subjects in each of 
3 arms. 
 
 
Inclusion Criteria 
To be randomized, all subjects must meet the criteria listed below. 
1. Males and females between 40 and 80 years of age, inclusive, at the time of consent. 
2. Diagnosis of IPF within 5 years before Visit 1a, confirmed by the Principal Investigator (PI) 
using American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese 
Respiratory Society (JRS)/Latin American Thoracic Association (ALAT) guidelines (Raghu 
et al, 2011 or Raghu et al, 2018; see Section 11.2.5). 
a. Clinical management of the patient at the site must be for IPF and the PI must be 
convinced that all locally available information support UIP/IPF is the most likely 
diagnosis. It is mandatory that the PI consider overreader interpretation of Visit 1b 
HRCT and, if performed, SLB in order to determine that a subject is eligible for this 
trial. 
3. Extent of fibrosis greater than emphysema on HRCT. 
4. If on pirfenidone or nintedanib, unchanged dose for at least 12 weeks before Visit 1a. 
Subjects may not be on both pirfenidone and nintedanib.

Statistical Methods 
Populations of Interest: 
Safety Population: The safety population will include all subjects who receive at least 1 dose of study 
treatment. 
ITT Population: The intent-to-treat (ITT) population will include any randomized subjects. 
PK Population 1: This PK population will include subjects in the PK subset who receive at least 
1 dose of study treatment and have a majority of scheduled PK samples drawn for serial PK 
measurements that allow for PK parameters to be generated. Subjects who do not complete the study 
treatment infusion (Visit 2) will be excluded from the PK analysis. 
PK Population 2: This PK population will include subjects who receive the majority of the study 
treatment doses and also have a majority of the planned trough samples collected that allow for a 
comparison of trough levels across dosing weeks. 
Per Protocol Population: This population will exclude nonevaluable subjects and subjects with major 
protocol deviations thought to impact the ability to assess the effect of study treatment. Exclusion of 
subjects from the Per Protocol (PP) set will be reviewed, documented, and approved before the study 
is unblinded to the study Sponsor. The criteria for excluding subjects from the PP population will be 
specified in the Statistical Analysis Plan (SAP).

Demographic and Baseline Characteristics: 
The safety population will be used for summary of demographic and baseline characteristics. 
Demographic and baseline laboratory results will be summarized overall and by treatment arm using 
descriptive statistics. Additionally, the proportion of subjects on SOC upon randomization for each 
treatment arm will be summarized.   
Safety: 
All safety analyses will be performed on the safety population. 
The analysis of safety, reported for each treatment arm, will be based on the frequency of AEs and 
their severity for all treated subjects. The safety variables, including AEs, SAEs, and AEs of interest 
(coded using the Medical Dictionary for Regulatory Activities [MedDRA]), clinical laboratory tests 
 physical examination, ECGs, and vital 
signs will be summarized or tabulated by treatment arm. Some of the variables will be tabulated by 
treatment arm and by visit. Incidence of AEs will be further tabulated by subjects on SOC within each 
treatment arm. 
The proportion of subjects discontinuing study treatment due to AEs will be tabulated by treatment 
arm.  
Biological Activity: 
All biological activity analyses will be performed on the ITT population.

Note: Refer to Section 18.6 for guidance on clinical trial conduct relating to COVID-19. 
a Screening begins with the first Visit 1a procedure (excluding signing the ICF) and may be shorter than 42 days. If possible, plan Visit 1b and schedule the 
 at the time of 
Visit 1a. To assure that an ineligible subject does not undergo an unnecessary 
ALL Visit 1a procedures MUST be completed before any Visit 1b procedures may be 
started.
 
 
b Subjects should be dosed on the study day listed in the Study Schedule (± 4 days for Visit 3 or ± 7 days for Visits 4 to 13), ensuring a minimum of 7 days between each dose. 
Assessments not associated with study treatment infusion may be performed on days other than the dosing day for scheduling purposes, as long as they are performed before the 
infusion. 
c The ICF should be signed before Visit 1a to allow the site to instruct the subject to withhold bronchodilator use as required for the Visit 1a PFT (see Section 11.2.2) 
 
 
d Adverse event and concomitant medication collection will begin 24 hours before Visit 1a. 
e On Day 2, study personnel will call subjects not returning to the site to collect any AEs and concomitant medications that may have occurred after leaving the site on Day 1. 
f Other abbreviated physical examinations may be performed at the discretion of the Investigator on the basis of signs or symptoms. See Section 11.1.3 for more information.

g During Visit 4 (Day 29), ECGs will be performed once, within 30 minutes after the end of the study treatment infusion. 
h Vital signs and SpO2 will be measured at every study visit, except at Visit 2 (Days 2 and 3; subjects participating in the PK substudy will only have vital signs measured). On 
dosing days vital signs and SpO2 will be measured thrice: once before the study treatment infusion (if premedication is administered, vital signs should be measured after 
premedication), midinfusion ± 5 minutes 
 
 and within 15 minutes after the end of the study treatment infusion. The frequency of monitoring vital signs may be increased as warranted by 
clinical management. See Section 11.1.4 and Section 11.2.1 for more information.  
 
 
 
 
 
 
 
 
 
 
 
o A positive urine pregnancy test will be followed up with a serum pregnancy test. 
 
 
 
r Every effort should be made to test for SARS-CoV-2 virus or viral antigen at Visit 1a if testing is available. The test used should have regulatory approval for marketing and 
sample collection should be performed per the assay’s specifications. Depending on the site and its location, options for subject testing may vary. Refer to Section 8.3.3 for 
guidance on SARS-CoV-2 testing.

ND-L02-s0201 for Injection is being developed for idiopathic pulmonary fibrosis (IPF) by Nitto 
Denko Corporation (Nitto). ND-L02-s0201 for Injection is a lipid nanoparticle (LNP) 
formulation 
 
 
 
 
5.1. 
Idiopathic Pulmonary Fibrosis 
Idiopathic pulmonary fibrosis is a specific form of chronic, progressive fibrosing interstitial 
pneumonia of unknown cause. It occurs primarily in older adults and is limited to the lungs. 
Idiopathic pulmonary fibrosis is characterized by progressive worsening of dyspnea and lung 
function and is associated with a poor prognosis (Raghu et al, 2011). The median survival of 
patients with IPF is generally 2.5 to 3.5 years (Ley et al, 2011). Respiratory failure resulting from 
disease progression is the most frequent cause of death (Ley et al, 2011). 
Pulmonary fibrosis was initially thought to be the result of chronic inflammation, but current 
evidence indicates it is the result of an epithelial-driven and fibroblast-activated process in which 
inflammation may have an ancillary role (Selman et al, 2001). Type II pneumocytes and 
myofibroblasts in usual interstitial pneumonia (UIP) overexpress and co-express HSP47 and type 
I procollagen. Studies have demonstrated expression of human HSP47 is increased in fibrotic 
lesions of IPF, idiopathic nonspecific interstitial pneumonia, and diffuse alveolar damage 
(Razzaque et al, 1998; Kakugawa et al, 2005) and HSP47 is detected in the serum of patients 
with acute exacerbated IPF (Kakugawa et al, 2013). Myofibroblasts, through the production of 
HSP47-associated regulation of type I procollagen, likely play an important role in the 
progression of pulmonary fibrosis (Iwashita et al, 2000).

Study ND-L02-s0201-005 
This Phase 2 clinical study will be a randomized, double-blind, placebo-controlled, multicenter 
study to evaluate the safety, tolerability, biological activity, and pharmacokinetics (PK) of 
ND-L02-s0201 for Injection in subjects with IPF. Approximately 120 subjects will be enrolled 
(approximately 40 subjects in each of 3 arms). Subjects will be randomized 1:1:1 to a low dose 
of ND-L02-s0201 (45 mg), a high dose of ND-L02-s0201 (90 mg), or placebo. Subjects will 
receive study treatment every 2 weeks (Q2W) for 24 weeks and will be followed until 12 weeks 
after the last dose. 
This trial will be conducted in compliance with the protocol, Good Clinical Practice (GCP), and 
the applicable regulatory requirement(s).

INVESTIGATIONAL PLAN 
7.1. 
Study Design 
This is a Phase 2, double-blind, placebo-controlled, randomized, multicenter, international study 
of 2 doses of ND-L02-s0201 for Injection to evaluate safety, tolerability, biological activity, and 
PK in subjects with a diagnosis of IPF. 
There will be 3 treatment arms. Two dose levels of ND-L02-s0201 will be evaluated in 2 arms: a 
low dose (45 mg) and a high dose (90 mg). A third arm will be administered placebo. 
The study will consist of a Screening period lasting up to 42 days, a 24-week treatment period 
including an End-of-Treatment (EOT) visit 2 weeks after the final dose (Visit 14), and 2 follow-
up (FU) visits 4 and 10 weeks after Visit 14. During the treatment period ND-L02-s0201 for 
Injection will be administered by intravenous (IV) infusion Q2W (± 4 days for Visit 3 or 
± 7 days for Visits 4 to 13, ensuring a minimum of 7 days between each dose) for a total of 
12 doses. Subject participation will be up to 281 days (approximately 40 weeks). The end of trial 
will be the last subject, last visit (LSLV). 
 
 
 
 
 
 
 
  
7.2. 
Randomization 
Approximately 120 eligible subjects will be randomly assigned 1:1:1 to 1 of 3 treatment arms: 
low dose ND-L02-s0201 for Injection (45 mg), high dose ND-L02-s0201 for Injection (90 mg), 
and a placebo arm. The randomization schedule will be prepared by an unblinded statistician.

7.3. 
Blinding 
Unblinded study personnel will prepare and administer the study treatment. The Investigator and 
other members of staff involved with the study will remain blinded to the study treatment 
randomization code until the final database is locked. 
 
 
 
7.4. 
Data Monitoring Committee 
To ensure safety of the overall study an independent Data Monitoring Committee (DMC) will be 
established. The DMC will periodically review the safety and tolerability of study treatment for 
the duration of the study. The DMC will include a chairperson and pulmonologist who are 
experienced in IPF; all members will be experienced with clinical trials and evaluating AEs, and 
will not otherwise participate in the study. The DMC will also include an independent 
statistician. 
The DMC will review all available AEs, safety laboratory data, declines in pulmonary function 
tests meeting thresholds defined in Section 11.2.2, 
 at 
preset times. The first scheduled meeting will occur after 25% of subjects have completed 
1 month of the study (ie, Visit 4, Day 29). The second scheduled meeting will occur after 50% of 
subjects have completed Visit 4 (Day 29). The third scheduled meeting will occur after 75% of 
subjects have completed Visit 8 (Day 85). All data listed for all subjects available at the time of 
the meeting will be included for review. 
Following review, the DMC will recommend continuation, modification, or discontinuation of 
the study based on observed toxicities. A DMC charter will describe the activities of this 
committee. 
In the event of unexpected AE or serious adverse event (SAE) findings or other critical safety-
related issues (eg, the coronavirus disease [COVID-19] pandemic), Nitto or the DMC may 
convene an ad hoc meeting. Such a meeting will outline the cause of concern and may identify a 
data cut-off as part of the scheduling request.

8.3.2. 
Other Eligibility Criteria Assessments 
Subjects with a confirmed diagnosis of IPF per this protocol’s eligibility criteria who fail 
Screening may be rescreened once if there is a change in status that, in consideration of protocol 
criteria by the Investigator and Medical Monitor, would allow participation in the study. 
8.3.3. 
COVID-19 Considerations 
8.3.3.1. 
Screening 
Refer to exclusion criterion 20 for eligibility restrictions related to suspected or confirmed 
SARS-CoV-2 infection. 
In terms of exclusion criterion 20c, every effort should be made to test for SARS-CoV-2 virus or 
viral antigen at Visit 1a if testing is available. The test used should have regulatory approval for 
marketing and sample collection should be performed per the assay’s specifications. Depending 
on the site and its location, options for subject testing may vary. Therefore, any of the following 
testing options are acceptable and are listed in order of preference: 
• Local testing performed concurrent with Visit 1a. 
• If local testing is not possible, testing should be performed using the central 
laboratory (if this option is in place and available to the site). 
• If neither local nor central laboratory SARS-CoV-2 testing are available, exclusion 
criterion 20c may be omitted in subjects who do not meet either criterion 20a or 20b. 
In this case, it should be properly documented in eCRF. 
• Detection of antibody to SARS-CoV-2 is not exclusionary. 
If a subject has a positive result from any test to detect SARS-CoV-2 virus or viral antigen 
within 21 days prior to Visit 1a: 
• If this finding is identified before signing the informed consent, the subject should not 
be consented until asymptomatic > 21 days. 
• If the finding is identified after signing the consent, the subject should be considered 
a screen failure with the option to rescreen as detailed in Section 8.3.3.2. 
If local or central SARS-CoV-2 testing is performed, the result should be available and reviewed 
before Visit 1b HRCT is conducted, consistent with Section 12.1. If the SARS-CoV-2 test is 
positive, the Visit 1b HRCT will not be performed. 
8.3.3.2. 
Rescreening 
A subject who was ineligible due to exclusion criterion 20 or details in Section 8.3.3.1, may 
rescreen in the following situations: 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
44 
 
 
• The subject has been asymptomatic > 21 days after exposure to a person as described 
in exclusion criterion 20a. 
• The subject’s signs and symptoms of SARS-CoV-2 infection have completely 
resolved > 21 days prior to the planned date of Rescreening. 
• The subject is asymptomatic for SARS-CoV-2 infection > 21 days after SARS-CoV-2 
virus or viral antigen was detected and prior to the planned date of Rescreening.

Subject Withdrawal 
8.4.1. 
Withdrawal Criteria 
Subjects may choose to withdraw from study treatment or the study at any time for any reason. 
In addition, subjects must have study treatment discontinued for any of the following reasons:  
• The subject is unwilling or unable to adhere to the protocol. 
• The subject becomes pregnant or begins breastfeeding. 
• The subject experiences an SAE, clinically significant AE, severe laboratory 
abnormality, intercurrent illness, or other medical condition that indicates to the 
Investigator that continued participation is not in the best interest of the subject. 
• 
 
 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
45 
 
 
• Another medical reason, at the discretion of the Investigator and/or the Medical 
Monitor that indicates continued participation is not in the best interest of the subject.  
The only reason for withdrawal from the study should be subject withdrawal of consent to 
participate.
 
 
 Subjects who discontinue study treatment should be followed for 
outcomes as long as they agree to continued participation in the study. 
8.4.2. 
Withdrawal Procedures 
If it is necessary for a subject to discontinue study treatment before completion, the subject 
should complete all ET and follow-up procedures (refer to Section 12.3 and Section 12.4) if he or 
she is willing and it is not medically contraindicated. At a minimum, all safety-related 
procedures should be performed. Refer to Section 18.6 for guidance on clinical trial conduct 
relating to COVID-19. 
The Investigator must notify the Sponsor and/or the Medical Monitor within 24 hours when a 
subject has discontinued study treatment because of an AE. Any subject who discontinued study 
treatment because of a treatment-related AE (whether serious or nonserious), including clinically 
significant abnormal laboratory test results, will be evaluated by the Investigator or a designee 
and will be treated and/or monitored until resolution, stabilization, or until it has been determined 
that the study treatment or participation is not the cause. 
If a subject does not return for a scheduled visit, every effort should be made to contact the 
subject. The Investigator or designee should inquire about the reason and will contact the subject 
by telephone as scheduled to collect AE information. 
If the subject discontinues study treatment and also withdraws consent for disclosure of future 
information, no further evaluations will be performed, and no additional data will be collected. 
The Sponsor may retain and continue to use data collected before consent was withdrawn. 
8.4.3. 
Documentation of Withdrawal 
The reason(s) for discontinuation of study treatment or withdrawal of consent must be recorded 
in the subject’s electronic case report form (eCRF). 
8.4.4. 
Replacement of Subjects 
Subjects who withdraw from the study will not be replaced. Subjects whose participation in the 
study was affected by restrictions relating to COVID-19 may be replaced if necessary to achieve 
this trial’s objectives. 
8.4.5. 
Stopping Rules 
Subjects will be monitored for evidence of drug-induced liver injury based on regulatory 
guidelines.

10.2.2.2. Nintedanib 
Subjects who are taking nintedanib at the start of the study should be instructed to take 
nintedanib in accordance with the prescribing information. Dose adjustment or discontinuation of 
SOC in accordance with the prescribing information is permitted if clinically indicated (see 
OFEV® Package Insert, 2018). On days when ND-L02-s0201 for Injection is being administered, 
subjects should take the morning dose of nintedanib before the infusion. On days when overnight 
fasting is required for sample collection, subjects should take nintedanib with their first meal of 
the day as prescribed (ie, after blood samples are collected). 
10.2.2.3. Pirfenidone 
Subjects who are taking pirfenidone at the start of the study should be instructed to take 
pirfenidone in accordance with the prescribing information. Dose adjustment or discontinuation 
of SOC in accordance with the prescribing information is permitted if clinically indicated (see 
ESBRIET® Package Insert, 2017). On days when ND-L02-s0201 for Injection is being 
administered, subjects should take the first dose of pirfenidone before the infusion. On days 
when overnight fasting is required for sample collection, subjects should take pirfenidone with 
their first meal of the day as prescribed (ie, after blood samples are collected). 
10.2.3. 
Dose Interruption 
Any interruption or other change in the study treatment infusion must be documented (see 
Section 10.4).  
10.3. 
Prior and Concomitant Medications 
All medications taken within 14 days before Visit 1a through end of study should be recorded in 
the eCRF. 
10.3.1. 
Prior Medications 
Prior medications are those taken within 14 days before Visit 1a until 24 hours before Visit 1a, or 
a longer period as specified in the exclusion criteria (see Section 8.2).  
10.3.2. 
Concomitant Medications 
Concomitant medications are those taken beginning 24 hours before Visit 1a.  
10.3.2.1. Premedication 
Refer to Section 18.5 for more information. 
10.3.2.2. Pirfenidone or Nintedanib 
If the subject has been taking either pirfenidone or nintedanib at an unchanged dose for at least 
12 weeks before Visit 1a (Section 8.1), the same medication should be continued during the 
subject’s participation in this trial. The dose of the medication should remain the same during the

subject’s participation in the study. However, dose adjustment or discontinuation of SOC in 
accordance with the prescribing information is permitted if clinically indicated. 
If the subject is not taking either pirfenidone or nintedanib at Screening, neither medication may 
be taken through Week 24 (Visit 14) or ET. After the collection of data at Week 24 (Visit 14) 
subjects may begin taking either medication at the discretion of the study doctor. Subjects may 
not be taking both pirfenidone and nintedanib during the study.  
10.3.2.3. Contraceptives 
Female Subjects 
Female subjects of childbearing potential must use a highly effective method of contraception 
during participation in the study and study follow up or for 90 days after the last dose of study 
treatment.  
Methods of contraception considered highly effective include 1 of the 5 listed below: 
1. Hormonal contraception (eg, injection, implant, pill, patch, or vaginal ring as available in 
each country) associated with inhibition of ovulation (both estrogen and progestogen and 
progestogen only) in use for at least 30 days before administration of study treatment 
2. Intrauterine device in use for at least 30 days before administration of study treatment 
3. Intrauterine hormone-releasing system (IUS) in use for at least 30 days before 
administration of study treatment 
4. Bilateral tubal occlusion/ligation at least 6 months before administration of study 
treatment 
5. Partner who has been vasectomized at least 6 months before administration of study 
treatment 
Note: A woman is considered to be of nonchildbearing potential if she meets one of the 
following criteria: a) postmenopausal with at least 12 months of spontaneous amenorrhea; b) has 
had a bilateral oophorectomy; or c) has had a hysterectomy. 
Male Subjects  
All males must agree to use a condom throughout the study and for 90 days after the last dose of 
study treatment to prevent seminal transmission of the IP. 
In addition, males with female partners of childbearing potential must agree to use a highly 
effective method of contraception (see above) throughout the study and for 90 days after the last 
dose of study treatment. 
10.3.2.4. Insulin 
If the subject has diabetes, instruct them to adhere to the following recommendations to make 
sure that fasting is safe. 
If the subject does not take insulin for diabetes, instruct them to: 
• Not take any oral diabetes medications while fasting; 
• Drink 250 mL (around 8 oz) of plain water every 4-6 hours prior to blood sampling; 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
52 
 
 
• Eat a meal or snack after blood sample(s) is/are collected; 
• Resume medications after eating the meal or snack. 
If the subject does take insulin for diabetes, instruct them to: 
• If on a basal injectable insulin dose (intermediate of long acting) the recommendation 
is to reduce normal insulin dose by one half or one third of the usual total morning 
dose depending on the fasting blood glucose in the morning after awakening; 
• Omit any short-acting (eg, regular) or rapid-acting (eg, lispro, aspart, glulisine) 
insulin prior to blood sampling; 
• If on continuous insulin infusion (insulin pump), the usual basal infusion rate does not 
need to be adjusted; 
• Drink 250 mL (around 8 oz) of plain water every 4-6 hours prior to blood sampling; 
• Eat a meal or snack after blood sample(s) is/are collected; 
• Resume short-acting (eg, regular) or rapid-acting (eg, lispro, aspart, glulisine) insulin 
after eating the meal or snack. 
10.3.2.5. Other 
After enrollment into the study, every attempt should be made to avoid changes in the subject’s 
medication regimen. Exceptions would include episodes of infections requiring treatment (eg, 
antibiotics or antiviral drugs), exacerbations of their underlying disease requiring immediate 
intervention, or any other situation requiring modification of the subject’s therapy for their safety 
at the discretion of the treating physician or the Investigator. 
10.3.3. 
Prohibited Medications 
Subjects should not be receiving high dose corticosteroids (ie, > 15 mg/day of prednisone or its 
equivalent), cytotoxic agents (eg, azathioprine, cyclophosphamide, methotrexate), unapproved 
IPF-targeted therapy, or cytokine modulating agents while participating in this study, nor can 
they have received such within 8 weeks or 5 half-lives (whichever is longer) before Visit 1a.  
Note: a dose of ≤ 15 mg/day prednisone, or equivalent, is acceptable if unchanged for 
≥ 10 weeks before Visit 1a and is expected to remain unchanged during the subject’s 
participation in the study.  
Note: a systemic dose of corticosteroid may be administered as premedication (see Section 18.5). 
 
 
10.4. 
Subject Compliance 
Study treatment will be administered at the study center by study center personnel.

Blood samples and urine samples will be collected for clinical laboratory testing as shown in 
Table 1. If needed, additional blood samples may be taken for DLCO correction. See 
Section 8.4.5 for guidance on how to manage subjects with elevations in transaminases. 
11.1.3. 
Physical Examinations 
Physical examinations will be conducted by the Investigator or qualified designee. A complete 
physical examination will include the following body systems: general appearance, 
eyes/ears/nose/throat/head/neck, chest and lungs (including inspection of the thorax for scars 
consistent with surgical lung biopsy at Screening), cardiovascular, abdomen, musculoskeletal, 
lymphatic, dermatologic, neurologic, psychiatric, and extremities. A complete physical 
examination, including recording of weight, will be conducted as shown in Table 1.  
An abbreviated physical exam includes general appearance, nose/throat, jugular venous 
distension (sitting; absent or present), auscultation of the lungs (anterior/posterior, 4 quadrants; 
wheezes, crackles, rhonchi [absent or present], other sounds [describe]), auscultation of the heart, 
lower extremity venous distention (absent or present), pitting edema (0, 1+, 2+, 3+, or 4+). An 
abbreviated physical examination will be performed as shown in Table 1. Other abbreviated 
physical examinations may be performed at the discretion of the Investigator on the basis of 
signs or symptoms.
 
 
Height (not a safety assessment) will be recorded only at Visit 1a. 
11.1.4. 
Vital Signs 
Vital signs will include systolic and diastolic blood pressure, heart rate, respiration rate, and oral 
temperature and will be measured at every study visit as shown in Table 1. All measurements 
should be performed in the semisupine or sitting position after the subject has rested in that 
position for at least 5 minutes. When feasible, vital signs should be performed in the same 
position at each visit. Blood pressure may be obtained with an automated or manual blood 
pressure apparatus; however, the same method should be used for any given subject throughout 
the study. Blood pressure and heart rate should be measured in the arm opposite that used for 
infusion of study treatment, and the arm used should be documented. 
Vital signs will be measured according to the following schedule:  
• Once before the study treatment infusion (if premedication is administered, vital signs 
should be measured after premedication) 
• midinfusion ± 5 minutes (if infusion is administered at a modified rate due to an 
infusion-related reaction, the timing should correspond to the middle of the modified 
infusion duration) 
• Within 15 minutes after the end of the study treatment infusion 
The frequency of monitoring vital signs may be increased as warranted by clinical management. 
If an AE occurs during the study treatment infusion, vital signs will be measured within 
5 minutes of the start of the AE and repeated at a minimum frequency of every 15 minutes until 
its resolution.

11.1.5. 
12-Lead Electrocardiograms 
Standard single 12-lead electrocardiograms (ECGs) will be performed after subjects have been 
resting for 5 minutes. If possible, the same model of ECG machine using the same algorithms 
should be used for any given subject for all assessments throughout the study. Heart rate as well 
as RR, PR, QRS, QT, and QTcF (QT interval corrected using Fridericia’s formula) intervals will 
be recorded in the eCRF. The Investigator should recalculate intervals and over read the machine 
interpretation, as necessary. A global interpretation of the ECG will be recorded as to whether 
the ECG is within normal limits or abnormal with any clinically significant findings noted.  
Standard 12-lead ECGs will be performed as shown in Table 1. During Visit 4, ECGs will be 
performed once, within 30 minutes after the end of the study treatment infusion. Additional 
ECGs may be performed if clinically indicated. 
Clinically significant changes not already noted or significantly worsened than documented in 
Medical History will be recorded as AEs.

At each study visit after signing the informed consent through to the FU visit, subjects will be 
asked about medications taken. 
11.2. 
Biological Activity 
11.2.1. 
Pulse Oximetry 
Pulse oximetry (SpO2) will be performed with vital signs as shown in Table 1. 
 
 
 
 
 
 
 
 
All documentation must include whether SpO2 was measured with the subject breathing ambient 
air or supplemental oxygen; if on supplemental oxygen, the flow and means of administration 
must also be recorded. When feasible, SpO2 measurements will be performed with the subject in 
the same position at each visit.  
SpO2 will be measured (with vital signs) according to the following schedule:  
• Once before the study treatment infusion (if premedication is administered, vital signs 
should be measured after premedication) 
• midinfusion ± 5 minutes (if infusion is administered at a modified rate due to an 
infusion-related reaction, the timing should correspond to the middle of the modified 
infusion duration) 
• Within 15 minutes after the end of the study treatment infusion

The frequency of monitoring may be increased as warranted by clinical management. If an AE 
occurs during the study treatment infusion, SpO2 will be measured within 5 minutes of the start 
of the AE and repeated at a minimum frequency of every 15 minutes until its resolution. 
 
 
 
 
11.2.2. 
Pulmonary Function Testing 
11.2.2.1. General Guidelines 
Pulmonary function testing will include both DLCO and spirometry. 
Pulmonary function testing (PFT) for this trial will be conducted in accordance with the PFT 
Manual that will be provided by the central PFT vendor for these services. The manual will 
include information on equipment and subject test instructions. 
 
 
 
 
 
 
PFT may only be performed on subjects in this trial by site personnel who have been determined 
by the PFT vendor to meet certification criteria. Whenever possible, all PFTs on a single subject 
should be performed: 
• on the same equipment 
• by the same site personnel 
• under the same conditions 
The Global Lung Initiative (GLI) 2012 spirometry reference values (Quanjer et al, 2012) and the 
GLI 2017 DLCO (TLCO) reference values (Stanojevic et al, 2017) will be used for all PFTs.  
11.2.2.2. Timing 
 
 
 
Timing of PFT and Bronchodilators 
All PFT on a single subject should be performed at the same time of day (± 2 hours). All PFT for 
this trial should be performed after withholding prescribed bronchodilators, either beta-agonists 
or anticholinergic agents, as follows: 
• short acting agents, typically prescribed on an as needed basis, withheld 4 hours 
before the study visit 
• twice daily agents, withheld 12 hours before the study visit 
• once daily agents, withheld 24 hours before the study visit 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
59 
 
 
Note that inhaled corticosteroids are not bronchodilators and may continue to be taken prior to 
PFT without a change in schedule. 
All PFT will only be performed prebronchodilator; there will be no postbronchodilator testing. 
The requirement to withhold prescribed bronchodilators prior to PFT is especially important 
before the first Screening PFT (Visit 1a). If a subject is taking prescribed bronchodilators, then 
the first Screening PFT may not be performed on the day that informed consent is obtained; it is 
not acceptable to alter the SOC to accommodate research specifications until after informed 
consent has been obtained. After informed consent has been obtained, subjects should be 
provided a reminder to withhold prescribed bronchodilators before each subsequent study visit 
when PFT will be performed. If a subject should present for PFT on any occasion other than the 
first Screening visit having forgotten to withhold prescribed bronchodilators for the specified 
time(s), PFT should be delayed as long as possible but still performed at that visit and within the 
window specified above; an appropriate notation must be captured in source records and the 
corresponding eCRF.

 In the event the repeat PFT is 
scheduled when the subject’s status has continued to deteriorate and either the subject or the 
Investigator determines testing is not feasible: 
• a notation that PFT was “not possible” should be entered into the corresponding 
eCRF and the most recent PFT results will be used for statistical analysis 
• a notation that PFT was “not possible” should be recorded in source records

Diagnosis of Idiopathic Pulmonary Fibrosis 
The diagnosis of IPF will be confirmed by the PI using ATS/ERS/JRS/ALAT consensus criteria 
(Raghu et al, 2011 or Raghu et al, 2018).  
Clinical management of the patient at the site must be for IPF and the PI must be convinced that 
all locally available information support that UIP/IPF is the most likely diagnosis. It is 
mandatory that the PI consider overreader interpretation of Visit 1b HRCT and, if performed, 
SLB in order to determine that a subject is eligible for this trial. 
The diagnosis of IPF may be made on the basis of HRCT and, when performed, SLB patterns in 
accordance with respective tables in the guidelines. Additional clinical data may also be used. In 
accordance with local implementation of the guidelines the diagnosis of IPF may also be 
established by review of the case at multidisciplinary discussion (MDD). 
Documentation of the diagnosis must be included in the subject’s source records.

STUDY PROCEDURES  
All study visits, assessments, and procedures involving study subjects will be performed at a 
Sponsor-approved Investigator site, and assessments and procedures will be performed by study 
center personnel under the supervision of the Investigator. The Investigator may perform 
unscheduled assessments not specified in this protocol to ensure subject safety. All 
measurements performed and results obtained during the study will be recorded in the eCRF. 
The informed consent form (ICF) should be signed before Visit 1a to allow the site to instruct the 
subject to withhold bronchodilator use as required for the PFT (Section 11.2.2) 
 
 A signed and

Statistical Plan 
13.2.1. 
Populations of Interest 
Safety Population: The safety population will include all subjects who receive at least 1 dose of 
study treatment. 
ITT Population: The intent-to-treat (ITT) population will include any randomized subjects. 
PK Population 1: This PK population will include subjects in the PK subset who receive at least 
1 dose of study treatment and have a majority of scheduled PK samples drawn for serial PK 
measurements that allow for PK parameters to be generated. Subjects who do not complete the 
study treatment infusion (Visit 2) will be excluded from PK analysis. 
PK Population 2: This PK population will include subjects who receive the majority of the study 
treatment doses and also have a majority of the planned trough samples collected that allow for a 
comparison of trough levels across dosing weeks. 
Per Protocol: This population will exclude nonevaluable subjects and subjects with major 
protocol deviations thought to impact the ability to assess the effect of study treatment. 
Exclusion of subjects from the Per Protocol (PP) set will be reviewed, documented, and 
approved before the study is unblinded to the study Sponsor. The criteria for excluding subjects 
from the PP population will be specified in the SAP. 
13.2.2. 
Demographic and Baseline Characteristics  
The safety population will be used for summary of demographic and baseline characteristics.

interest (coded using the Medical Dictionary for Regulatory Activities [MedDRA]), clinical 
laboratory tests 
 physical 
examination, ECGs, and vital signs will be summarized or tabulated by treatment arm. Some of 
the variables will be tabulated by treatment arm and by visit. Incidence of AEs will be further 
tabulated by subjects on SOC within each treatment arm. 
The proportion of subjects discontinuing study treatment due to AEs will be tabulated by 
treatment arm.

ADVERSE EVENTS 
14.1. 
Adverse Event Definitions 
14.1.1. 
Adverse Event 
An AE means any untoward medical occurrence associated with the use of a drug in humans, 
whether or not considered drug-related. An AE (also referred to as an adverse experience) can be 
any unfavorable and unintended sign (eg, an abnormal laboratory finding), symptom, or disease 
temporally associated with the use of a drug and does not imply any judgment about causality. 
An AE can arise with any use of the drug (eg, off-label use, use in combination with another 
drug) and with any route of administration, formulation, or dose, including an overdose. 
14.1.2. 
Suspected Adverse Reaction  
Any AE for which there is a reasonable possibility that the drug caused the AE. For the purposes 
of Investigational New Drug (IND) safety reporting, ‘‘reasonable possibility’’ means there is 
evidence to suggest a causal relationship between the drug and the AE. Suspected adverse 
reaction implies a lesser degree of certainty about causality than adverse reaction, which means 
any AE caused by a drug. 
14.1.3. 
Life-Threatening Adverse Event or Life-Threatening Suspected Adverse 
Reaction 
An AE or suspected adverse reaction is considered ‘‘life-threatening’’ if, in the view of either the 
Investigator or Sponsor, its occurrence places the subject at immediate risk of death. It does not 
include an AE or suspected adverse reaction that, had it occurred in a more severe form, might 
have caused death. 
14.1.4. 
Serious Adverse Event or Serious Suspected Adverse Reaction  
An AE or suspected adverse reaction is considered ‘‘serious’’ if, in the view of either the 
Investigator or Sponsor, it results in any of the following outcomes: 
• Death 
• A life-threatening AE – see definition above  
• Admission to the hospital or prolongation of existing hospitalization1 
• A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions 
• A congenital anomaly/birth defect  
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, they 
may jeopardize the subject and may require medical or surgical intervention to prevent one of the 
outcomes listed in this definition. Examples of such medical events include allergic 
 
1 Admission to the hospital for a scheduled PK blood sample collection will not be considered an SAE. If the 
planned hospitalization should be prolonged due to an AE, an SAE would need to be documented. 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
81 
 
 
bronchospasm requiring intensive treatment in an emergency room or at home, blood dyscrasias 
or convulsions that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse. 
14.1.5. 
Unexpected Adverse Event or Unexpected Suspected Adverse Reaction 
An AE or suspected adverse reaction is considered ‘‘unexpected:’’  
• If it is not listed in the Investigator Brochure or is not listed at the specificity or 
severity that has been observed, or  
• If an Investigator Brochure is not required or available, is not consistent with the risk 
information described in the general investigational plan or elsewhere in the current 
application, as amended.  
For example, under this definition, hepatic necrosis would be unexpected (by virtue of greater 
severity) if the Investigator Brochure referred only to elevated hepatic enzymes or hepatitis. 
Similarly, cerebral thromboembolism and cerebral vasculitis would be unexpected (by virtue of 
greater specificity) if the Investigator Brochure listed only cerebral vascular accidents.  
‘‘Unexpected,’’ as used in this definition, also refers to AEs or suspected adverse reactions that 
are mentioned in the Investigator Brochure as occurring with a class of drugs or as anticipated 
from the pharmacological properties of the drug, but are not specifically mentioned as occurring 
with the particular drug under investigation. 
14.2. 
Adverse Event Classification 
14.2.1. 
Treatment-Emergent Adverse Events 
An AE is defined as treatment-emergent if it occurs at or after the first dose of study treatment 
and through 2 weeks after the last dose of study treatment. This also includes AEs which are 
observed before the first dose of study treatment and increase in severity after the first dose 
through 2 weeks after the last dose of study treatment. 
Note: 2 weeks after the last dose of study treatment was selected because it is expected to be 
longer than 5 times the terminal half-life of ND-L02-s0201. 
 
 
 
 
 
  
14.2.4. 
Respiratory Adverse Events 
It is recognized that exacerbations of IPF occur and that they may be preceded by indolent 
symptoms. These indolent symptoms should be recorded per the site’s customary practices for 
reporting AE. When a subject’s status progresses to include sufficient respiratory deterioration, 
imaging findings, histopathology, and/or clinical interventions consistent with exacerbation of 
IPF, AE reporting should convert to this term as long as it is the same event. If the Investigator 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
82 
 
 
determines that there is a relationship between the AE (eg, upper respiratory tract infection) and 
the exacerbation, the former term should be modified to indicate the relationship (eg, upper 
respiratory tract infection preceding IPF exacerbation or upper respiratory tract infection-related 
to IPF exacerbation). If the time-relationship is unclear, separate AEs are appropriate and IPF 
exacerbation should be captured as a new event.  
14.2.5. 
Acute Exacerbation of IPF 
Idiopathic pulmonary fibrosis exacerbation is defined as an unexplained worsening of dyspnea, 
evidence of hypoxemia as defined by worsened or severely impaired gas exchange, new 
radiographic alveolar infiltrates, and an absence of an alternative explanation such as infection, 
pulmonary embolism, pneumothorax, or heart failure (Raghu et al, 2011). 
 
 
 
 
 
 
 
 
 
 
 
 
14.2.7. 
Relationship to Study Treatment, Premedication, and Standard of Care 
Relationship to study treatment, premedication, and standard of care will be assessed. Hereafter 
referred to as drug in this section. 
The Investigator’s assessment of causality must be provided for all AEs (serious and nonserious). 
An Investigator’s causality assessment is the determination of whether there exists a reasonable 
possibility that the drug caused or contributed to an AE. The possibility of a causal relationship 
means that there are facts, ie, evidence, or arguments to suggest a causal relationship. Adverse 
events with a relationship of “none” are considered not related to drug. All other AE relationship 
(unlikely, possible, probable, and definite) are considered related to drug. 
Clinical judgement should be used to determine the relationship of drug to the AE. The 
Investigator should consider, for example, all relevant and/or alternative causes, including 
pattern of the reaction, temporal relationship, de-challenge, re-challenge, underlying disease(s), 
concomitant therapy(ies), concomitant illness(es), risk factor(s), and medical history. 
None: 
No relationship between the experience and the administration of drug; related to 
other etiologies such as concomitant medications or subject’s clinical state. 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
83 
 
 
Unlikely: 
The current state of knowledge indicates that a relationship is unlikely. However, 
as a causal relationship to the drug cannot be ruled out, the causal relationship 
will be classified as related to drug. 
Possible: 
A reaction that follows a plausible temporal sequence from administration of the 
drug and follows a known response pattern to the suspected drug. The reaction 
might have been produced by the subject’s clinical state or other modes of therapy 
administered to the subject, but this is not known for sure. 
Probable: 
A reaction that follows a plausible temporal sequence from administration of the 
drug and follows a known response pattern to the suspected drug. The reaction 
cannot be reasonably explained by the known characteristics of the subject’s 
clinical state or other modes of therapy administered to the subject. 
Definite: 
A reaction that follows a plausible temporal sequence from administration of the 
drug and follows a known response pattern to the suspected drug and can be 
confirmed with a positive re-challenge test or supporting laboratory data. 
Note: AEs that occur after administration of premedication (if applicable) but before the 
administration of study treatment should not be reported as related to study treatment. 
Refer to the country-specific package insert of Summary or Product Characteristics for the risks 
and side effects associated with pirfenidone, nintedanib, and premedication (if applicable). 
14.2.8. 
Severity 
Grading of AEs will be done using the National Cancer Institute (NCI) Common Terminology 
Criteria for Adverse Events version 5.0 (CTCAE v5.0) 
(https://ctep.cancer.gov/protocoldevelopment/electronic_applications/ctc.htm#ctc_50).  
If an AE is not listed in the CTCAE v5.0, then the Investigator will use the terms: mild, 
moderate, severe, life-threatening, or death to describe the maximum intensity of the AE. For 
purposes of consistency, these intensity grades are defined as follows: 
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 
livinga 
Grade 3 
Severe or medically significant 
but not immediately life-
threatening 
Hospitalization or prolongation of hospitalization 
indicated; disabling; limiting self-care activities of daily 
livingb 
Grade 4 
Life threatening consequences 
Urgent intervention indicated 
Grade 5 
Death 
Death related to an adverse event 
a Instrumental activities of daily life refer to preparing meals, shopping for groceries or clothes, using the telephone, 
managing money, etc 
b Self-care activities of daily life refer to bathing, dressing and undressing, feeding self, using the toilet, taking 
medications, and not bedridden.

14.3. 
Exposure in Utero 
The subject will be instructed to notify the Investigator if the subject or subject’s partner 
becomes pregnant during the study, The Investigator must notify the Sponsor within 24 hours, 
and must complete the Pregnancy Notification Form and submit it to the Sponsor within 
2 working days of being notified. The Investigator should obtain informed consent/assent from 
the subject or subject’s partner allowing the Investigator to obtain information regarding the 
pregnancy and its outcome. If the subject or subject’s partner provides informed consent/assent, 
the Investigator should follow the pregnancy until outcome. A final Pregnancy Notification Form 
should be completed when the outcome of the pregnancy is known. 
14.4. 
Monitoring of Adverse Event Data 
To ensure safety of the overall study an independent DMC will be established. The DMC will 
periodically review the safety and tolerability of study treatment for the duration of the study. 
Refer to Section 7.4 for details.  
14.5. 
Documentation of Adverse Events by Investigator 
Subjects will be evaluated and questioned generally to identify AEs during the course of the 
study. Adverse event collection will begin 24 hours before Visit 1a. Adverse events that occur up 
to and including 12 weeks after administration of the last dose of study treatment, including ET, 
must be reported. 
All AEs spontaneously reported by the subject and/or in response to an open question from study 
personnel or revealed by observation, physical examination, or other diagnostic procedures will 
be recorded on the Adverse Event Form for that visit. Any clinically relevant deterioration in 
laboratory assessments, intercurrent illness, or other clinical findings is considered an AE and 
must be recorded on the Adverse Event Form. In addition, an abnormal test finding will be 
classified as an AE if one or more of the following criteria are met: 
• The test finding is accompanied by clinical symptoms. 
• The test finding necessitates additional diagnostic evaluation(s) or medical/surgical 
intervention; including significant additional concomitant drug treatment or other 
therapy. Note: simply repeating a test finding, in the absence of any of the other listed 
criteria, does not constitute an AE. 
• The test finding leads to a change in study treatment dosing or discontinuation of 
subject participation in the clinical research study. 
• The test finding is considered an AE by the Investigator. 
Wherever possible, a specific disease or syndrome rather than individual associated signs and 
symptoms should be identified. However, if an observed or reported sign or symptom is not 
considered a component of a specific disease or syndrome by the Investigator, it should be 
recorded as a separate AE. Laboratory data will be collected as stipulated in this protocol. 
Clinical syndromes associated with laboratory abnormalities will be recorded as appropriate 
(eg, diabetes mellitus rather than hyperglycemia).

For SAEs, a Serious Adverse Event Form must also be completed with as much information as 
possible and submitted in the time frame described below in Section 14.6. When new significant 
information is obtained as well as when the outcome of an event is known, the Investigator 
should record the information on a new SAE form. If the subject was hospitalized, a copy of the 
discharge summary and any other relevant hospital records (eg, admission report, laboratory test 
results, etc.) must be included as part of the subject medical file.  
The clinical course of each AE will be followed until resolution, stabilization, or until it has been 
determined that the study treatment or participation is not the cause.  
14.6. 
Notification about Serious Adverse Events and Serious and 
Unexpected Suspected Adverse Reactions 
14.6.1. 
Investigator Reporting to Sponsor 
All SAEs that occur during the course of the study must be reported by the Investigator to the 
Sponsor, designated representative, and Medical Monitor within 24 hours by fax or email. In 
addition, all SAEs that occur up to and including 12 weeks after administration of the last dose of 
study treatment must be reported to the Sponsor within 24 hours from when the Investigator 
becomes aware of the SAE. 
Investigators must report to the Sponsor all SAEs, whether or not considered drug-related, 
including those listed in the Investigator Brochure. The report must include an assessment of 
causality.  
For all SAEs, the Investigator is obligated to obtain and provide information to the Sponsor in 
accordance with the timeframes for reporting specified above. In addition, an Investigator may 
be requested by the Sponsor to obtain specific additional follow-up information in an expedited 
fashion. This information may be more detailed than that captured on the AE CRF. In general, 
this will include a description of the AE in sufficient detail to allow for a complete medical 
assessment of the case and independent determination of possible causality. Information on other 
possible causes of the event, such as concomitant medications and illnesses must be provided. In 
the case of a subject death, a summary of available autopsy findings must be submitted as soon 
as possible to the Sponsor or its designated representative. 
 
 
 
 
 
 
14.6.2. 
Reporting to Regulatory Agencies and Institutional Review Boards/Independent 
Ethics Committees 
If there is a serious and unexpected suspected adverse reaction, the Sponsor will notify the 
appropriate regulatory agency(ies) on an expedited basis. In addition, Sponsors must submit 
expedited reports of an increased rate of occurrence of serious suspected adverse reactions over 
that listed in the Reference Safety Information.

It is the responsibility of the Investigator to promptly notify the Institutional Review Board 
(IRB)/Independent Ethics Committee (IEC) of all serious and unexpected suspected adverse 
reactions involving risk to human subjects. 
14.7. 
Emergency Identification of Study Medication 
In the event of a medical emergency, when knowledge of the subject’s treatment assignment may 
influence the subject’s clinical care, the Investigator may obtain the treatment assignment of the 
subject experiencing the emergency. The Investigator can unblind individual subjects via the 
study IWRS. The Investigator will create a secure account and receive a username and password 
prior to enrolling subjects. After unblinding, the Investigator should contact the Medical 
Monitor. 
If unblinding is necessary, the Investigator must document the reasons for unblinding in the 
subject’s source documents but should not divulge the subject’s treatment assignment to any 
individuals except the Medical Monitor and those individuals involved in the direct care of the 
subject. The date and the reasons for breaking the blind must be submitted to the Sponsor within 
24 hours.  
If a subject’s treatment assignment is unblinded, the subject should remain in the study and 
continue the protocol-specified follow-up evaluations. 
14.8. 
Emergency Sponsor Contact 
In a medical emergency, a qualified healthcare provider will attend to the subject’s immediate 
clinical management, including administration of medical intervention according to the SOC.

The IRB/IEC will meet all FDA and applicable regulatory authority requirements governing 
IRBs/IECs in accordance with ICH GCPs.  
The Investigator will provide the Sponsor (or designee) with documentation of IRB/IEC 
approval of the following documents before the study begins at the study site(s): protocol, ICF, 
and any other relevant materials intended for or directed to subjects (eg, subject diaries, 
advertisements). The Investigator will supply documentation to the Sponsor (or designee) of 
IRB/IEC requirements regarding continuing review and approval of revisions to any of these 
documents. 
15.2. 
Ethical Conduct of the Study 
This study will be conducted in accordance with the current IRB/IEC approved clinical protocol, 
ICH GCP Guidelines, and relevant policies and requirements of the national regulations and 
laws, including the Health Insurance Portability and Accountability Act of 1996 (HIPAA). 
15.3. 
Subject Information and Informed Consent 
Written informed consent/assent is required from each subject before any testing under this 
protocol, including Screening tests and evaluations. The ICF, as specified by the clinical site’s 
IRB/IEC, must follow the Protection of Human Subjects regulations listed in 21 Code of Federal 
Regulations (CFR) Part 50 and ICH E6 4.8.  
The ICF will be used to explain the risks and benefits of study participation in simple terms 
before the subject will be entered into the study. The ICF will contain a statement that the 
consent is freely given, that the subject is aware of the risks and benefits of entering the study, 
and that the subject is free to withdraw from the study at any time. Written informed consent 
must be given by the subject after the receipt of detailed information on the study. It is the 
responsibility of the Investigator to obtain consent/assent and to provide the subject with a copy 
of the signed and dated ICF. Confirmation of a subject’s informed consent must also be 
documented in the subject’s medical record before any testing under this protocol, including 
Screening tests and evaluations. 
All ICFs used in this study must be approved by the appropriate IRB/IEC and by the Sponsor or 
its designee. The ICF must not be altered without the prior agreement of the relevant IRB/IEC 
and the Sponsor (or designee).

STUDY ADMINISTRATION 
16.1. 
Administrative Structure 
A list of individuals who will have key positions in this study will be saved in the Trial Master 
File (TMF). This list will include names, titles, and roles of selected individuals from the 
Sponsor (or designee) and the Contract Research Organization (CRO) that will contribute to this 
study. 
16.2. 
Quality Control and Quality Assurance 
16.2.1. 
Overview 
According to the GCP Guidelines, the Sponsor is responsible for implementing and maintaining 
quality assurance (QA) and QC systems with written SOPs.  
QC will be applied to each stage of data handling. The following steps will be taken to ensure the 
accuracy, consistency, completeness, and reliability of the data: 
• Investigator meeting(s); 
• Site initiation visit; 
• Routine site monitoring; 
• Ongoing site communication and training; 
• Data management quality control checks; 
• Continuous data acquisition and cleaning; 
• Internal review of data; and 
• QC checks of the final clinical study report (CSR). 
In addition, the Sponsor’s (or designee) Clinical QA Department may conduct periodic audits of 
the study processes, including, but not limited to study site, site visits, vendors, clinical database, 
and final CSR. When audits are conducted, access must be authorized to Sponsor’s 
representatives and regulatory authorities for all study-related documents, including medical 
history and concomitant medication documentation. 
16.2.2. 
Risk Management 
Program risks will be evaluated on an ongoing basis by the Sponsor in accordance with ICH 
E6 (R2) Section 5, and any important deviations from prespecified quality limits will be 
documented in the clinical study report. 
16.2.3. 
Monitoring 
The Sponsor has engaged the services of a CRO to perform all monitoring functions for this 
clinical study. Monitors will work in accordance with the CRO’s SOPs and have the same rights 
and responsibilities as monitors from the Sponsor organization. Monitors will establish and 
maintain regular contact between the Investigator or designee and the Sponsor. 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
89 
 
 
Monitors will evaluate the competence of each study site, informing the Sponsor about any 
problems relating to facilities, technical equipment, or medical staff. During the study, monitors 
will check that written informed consent/assent has been obtained from all subjects correctly and 
that data are recorded correctly and completely on the eCRFs. Monitors are also required to 
compare entries in eCRFs with corresponding source data and to inform the Investigator or 
designee of any errors or omissions. Monitors will also review adherence to the protocol and to 
regulatory requirements at the study site and discuss and deviations noted with the Investigator 
or designee. They will arrange for the study site to receive adequate supply of IP, review IP 
accountability records to IP supplies/subject use, and ensure appropriate storage conditions are 
maintained.  
In the event that onsite monitoring visits are not allowed due to health safety concerns, monitors 
will remotely monitor data entry into the database by site staff and may perform source data 
verification (if allowed by the site) to identify SAEs that may not have been reported by sites. As 
soon as feasible, onsite monitoring will resume, and data monitored remotely will be source data 
verified. 
Monitoring visits will be conducted according to the United States CFR Title 21 parts 50, 56, and 
312 and ICH Guideline for GCP. The monitor will make written reports to the Sponsor following 
each contact with the Investigator or designee, regardless of whether it is by phone or in person. 
16.2.4. 
Data Management/Coding 
Study data will be handled according to the relevant SOPs of the data management and 
biostatistics departments of the Sponsor (or designee) or CRO. 
AEs will be coded using MedDRA and medications will be coded using World Health 
Organization (WHO) Drug Dictionary Enhanced (WHODDE) drug dictionary. 
16.2.5. 
Quality Assurance Audit 
Study sites, the study database and study documentation may be subject to a QA audit by the 
Sponsor or designee on behalf of the Sponsor. In addition, inspections may be conducted by 
regulatory bodies at their discretion. 
16.3. 
Data Handling and Recordkeeping 
16.3.1. 
Electronic Data 
When using electronic trial data handling and/or remote electronic trial data systems, the Sponsor 
(or designee) will: 
• Ensure and document that the electronic data processing system(s) conforms to the 
Sponsor’s established requirements for completeness, accuracy, reliability, and 
consistent intended performance (ie, validation) 
• Maintain SOPs for using these systems 
• Ensure that the systems are designed to permit data changes in such a way that the 
data changes are documented and that there is no deletion of entered data (ie, 
maintain an audit trail, data trail, edit trail)

• Maintain a security system that prevents unauthorized access to the data 
• Maintain a list of the individuals who are authorized to make data changes 
• Maintain adequate backup of the data 
• Safeguard the blinding, if any (eg, maintain the blinding during data entry and 
processing) 
Documentation regarding electronic systems used in this protocol is available upon request from 
the CRO maintaining the electronic trial data system. 
16.3.2. 
Case Report Form Completion 
Electronic data capture will be used for the study. All data will be recorded on source 
documentation at each study location and entered electronically by the study center personnel. 
Data collected on each subject will be documented on the appropriate eCRF. Completed eCRFs 
will be signed off by the Investigator or his/her designee. 
16.3.3. 
Data Handling 
If data are transformed during processing, records will be maintained so that it will be possible to 
compare the original data and observations with the processed data. 
An unambiguous subject identification code will be used that allows identification of all the data 
reported for each subject. 
16.3.4. 
Retention of Study Records 
The Investigator must maintain essential study documents (protocol and protocol amendments, 
completed eCRFs, signed ICFs, relevant correspondence, and all other supporting 
documentation) until at least 2 years after the last approval of a marketing application in an ICH 
region and until there are no pending or contemplated marketing applications in an ICH region or 
at least 2 years after the formal discontinuation of clinical development of the IP. These 
documents will be retained for a longer period if required by the applicable regulatory 
requirements or the hospital, institution, or private practice in which the study is being 
conducted. Subject identification codes (subject names and corresponding study numbers) will 
be retained for this same period of time. These documents may be transferred to another 
responsible party, acceptable to the Sponsor, who agrees to abide by the retention policies. 
Written notification of transfer must be submitted to the Sponsor. The Investigator or designee 
must contact the Sponsor before disposing of any study records. 
16.4. 
Financing and Insurance 
Financing and insurance are addressed in a separate document. 
16.5. 
Confidentiality 
To maintain subject privacy, all eCRFs, study treatment accountability records, study reports and 
communications will identify the subject by the assigned subject number. The Investigator will 
grant monitor(s) and auditor(s) from the Sponsor or its designee and regulatory authority(ies) 
access to the subject’s original medical records for verification of data gathered on the eCRFs

and to audit the data collection process. The subject’s confidentiality will be maintained in 
accordance with applicable laws and regulations. 
Subjects will be informed that registration information, results, and other information about this 
study will be submitted to publicly available clinical trial registry databases in the United States, 
European Union, and Japan; however, protected health information of individual subjects will 
not be used. 
All information regarding the IP supplied by the Sponsor to the Investigator is privileged and 
confidential information. The Investigator agrees to use this information to accomplish the study 
and will not use it for other purposes without consent from the Sponsor. It is understood that 
there is an obligation to provide the Sponsor with complete data obtained during the study. The 
information obtained from the clinical study will be used toward the development of the IP and 
may be disclosed to regulatory authority(ies), other Investigators, corporate partners, or 
consultants as required. 
16.6. 
Publication Policy 
The data generated by this study are considered confidential information and the property of 
Sponsor and shall not be published or disclosed without the prior written consent of Sponsor. 
16.7. 
Direct Access to Source Data 
The Investigators/institutions clinical sites will permit trial-related monitoring, audits, IRB/IEC 
review, and regulatory inspections as requested by FDA or other regulatory authorities, the 
Sponsor, or the Sponsor designee, including direct access to source data/documents (ie, original 
medical records, laboratory reports, hospital documents, progress reports, signed ICFs, etc) in 
addition to eCRFs. 
The Investigator or designee will prepare and maintain adequate and accurate source documents 
to support all observations and other pertinent data recorded on the eCRFs for each subject 
enrolled in the study.   
The Investigator will allow the Sponsor (or designee) and authorized regulatory authorities to 
have direct access to all documents pertaining to the study. 
16.8. 
Protocol Amendments 
Changes to the conduct of the study should be prepared as a protocol amendment and 
implemented only upon joint approval of the Sponsor, or a representative of the Sponsor, and the 
Investigator. Protocol amendments should also receive written IRB/IEC approval before 
implementation, except when necessary to eliminate immediate hazards to the subjects or when 
the changes involve only logistical or administrative aspects of the trial (eg, change of monitor, 
telephone numbers). In this case, the Sponsor will amend and implement the protocol change and 
subsequently notify the regulatory authorities and/or the IRB/IEC, as appropriate.

Appendix F: Restrictions Relating to COVID-19 
This section describes safety measures that were taken due to the COVID-19 pandemic. These 
measures will also apply to subsequent outbreaks/pandemics resulting from SARS-CoV-2 
infections. 
18.6.1. 
Restrictions to Study Conduct 
The following will be taken into consideration when determining whether there are any 
restrictions to conducting onsite visits: 
• Local government/institution and hospital readiness to allow clinical research 
activities 
• Confirmed absence of COVID-19-related restrictions on mobility of persons (central, 
regional, & municipal government plus institutional) applicable to the trial 
candidates, subjects, or site personnel 
• Ability for clinical research associate (CRA) to perform onsite routine monitoring in 
accordance with the Monitoring Plan. 
• Confirmed ability to perform research PFT per protocol/established guidelines 
• Confirmed ability to perform research HRCT per protocol/established guidelines 
• Confirmed ability to process and ship central and local laboratory samples per 
protocol/established guidelines 
• Adequate stock of study supplies including laboratory kits, personal protective 
equipment, and study treatment preparation and administration materials  
• Unrestricted courier services 
The Investigator will be responsible for determining if it is safe to proceed with onsite study 
visits at his/her site considering the requirements above. If the Investigator determines that onsite 
study procedures are not feasible based on the criteria above, they must inform the IRB/IEC and 
advise the CRA or clinical trial lead (CTL). Recommendations for how to proceed if there are 
restrictions preventing onsite visits are included Section 18.6.2. 
To resume onsite study visits, the Investigator must inform the IRB/IEC and CRA or CTL after 
considering the guidelines above. 
18.6.2. 
Study Visit Guidelines 
18.6.2.1. Consenting and Screening 
When study procedures cannot be performed onsite, the Investigator should pause consenting of 
new subjects and suspend screening procedures for already consented subjects. Subjects who 
have been consented but have not received study treatment, should be considered screen failures 
(with the option to rescreen at a later time). If the Investigator believes these activities may 
resume after considering the guidelines in Section 18.6.1, the Investigator must inform the 
IRB/IEC and CRA or CTL. 

Clinical Protocol: Study ND-L02-s0201-005 
Amendment 05 
 
17 June 2020 
109 
 
 
18.6.2.2. Managing Treatment Period Study Visits 
When onsite study procedures cannot be performed for already randomized subjects, up to 
2 scheduled Treatment Period visits may be conducted remotely. The implementation of remote 
visits allows for a maximum delay in study treatment administration of 6 weeks after the last 
dose. Section 18.6.2.4 describes what data should be collected at a minimum during a remote 
visit. 
If onsite visits can resume and study treatment can be administered ≤ 6 weeks after the last dose, 
feasible study-related procedures should resume onsite as soon as possible per Section 12.2. In 
this case, the subject should proceed with the next protocol visit and follow those procedures. 
For example, if the subject has remote Visit 4 and Visit 5, and onsite visits can resume within 
6 weeks of their last dose of study treatment, the subject will resume the study and complete 
Visit 6 study procedures. 
18.6.2.3. Managing End-of-Treatment and Follow-Up Period Visits 
Subjects Who Complete Planned Treatment Period Visits 
If a subject completes all planned Treatment Period visits, remote or onsite through Visit 13, 
Visit 14 should be conducted per Section 12.3. If it is not safe or feasible to proceed onsite, 
Visit 14 may be postponed for up to 8 weeks after the last dose. If onsite Visit 14 will not be safe 
or feasible in ≤ 8 weeks after the last dose, the visit should be conducted remotely. If at any time 
circumstances change and it becomes safe and feasible for a subject to come to the site, 
subsequent visits should be performed onsite and follow procedures per Section 12 for the visits 
described below. 
a. Visit 14 performed onsite or remotely ≤ 8 weeks after Visit 13 
b. Visit 15 performed onsite or remotely 4 ± 1 week after Visit 14 
c. Visit 16 performed onsite or remotely 10 ± 1 week after Visit 14 
Subjects Who Do Not Complete Planned Treatment Period Visits 
If a subject misses 2 Treatment Period visits as described in Section 18.6.2.2, and it is not 
expected that study treatment administration can restart ≤ 6 weeks after the last dose, perform a 
remote ET visit. If circumstances change and it becomes safe and feasible for the subject to come 
to the site, ET and Follow-Up visits should be performed onsite and follow procedures per 
Section 12. 
a. ET visit performed onsite or remotely 2 ± 1 week after the second missed visit 
b. Visit 15 performed onsite or remotely 4 ± 1 week after ET visit 
c. Visit 16 performed onsite or remotely 10 ± 1 week after ET visit 
18.6.2.4. Data Collection During Remote Visits 
During remote visits, the following information should be collected at a minimum: 
1. Concomitant medications 
2. Adverse events (If the subject reports COVID-19, ask whether the infection has been 
confirmed via testing. If possible, the test used should be recorded.)
