STUDY DESIGN 
PRIMARY 
OBJECTIVE 
The study will evaluate the efficacy and safety of 2 dose levels of 
NTRA2112 on intestinal malabsorption in preterm infants as compared 
to placebo. 
NTRA-2112 is a powder of insulin formulation for reconstitution in 
breast milk, 
infant formula, 
normal 
and 
half-normal 
saline 
administered concomitantly with preterm infant's formula, donor 
breast milk, or own mother's breast milk for local gastrointestinal (GI) 
therapy. 
For both dose levels, the final obtained insulin concentration in the 
infant's nutrit ion is within physiological levels present in human breast 
colostrum milk and amniotic fluid during pregnancy. 
The study will enroll preterm infants weighing at least 500g born 
betw een 26 and up to 32 weeks of pregnancy who meet the inclusion 
and exclusion criteria. 
The effect on intestinal malabsorption will be evaluated by comparing 
the ability of preterm infants to achieve full enteral (EN) feeding for 3 
consecutive days. 
Infants will be treated for 28 days or until hospital discharge, the 
earliest. Patients would receive NTRA-2112 Treatment A to obtain 400 
µU/ ml -
equivalent dose of insulin or NTRA-2112 Treatment B to 
obtain 2000 µU/ ml dose of insulin or placebo as calculated according 
to planned daily enteral intake. 
During the treatment period, infants will undergo daily evaluation of 
AEs, concomitant medication, nutrition, general growth, gastric 
residuals, and development progression. 
Infants will be evaluated at day of discharge. Follow-up visits will be 
performed at 3 months, 12 months and 24 months corrected age. 
Infants will be permitted infant formula, donor breast milk (DBM) and 
own mother's milk (OMM). 
To assess the efficacy of 2 doses of NTRA-2112 as compared to placebo 
on intestinal malabsorption in preterm infants as measured by the 
t ime to full enteral feeding*.

PROCEDURES 
SAFETY 
EVALUATION 
NUMBER OF 
CENTERS 
The study physician will follow a recommended feeding protocol 
(Appendix A). The final feeding scheme is subject to the physician's 
clinical evaluation. 
Screening procedures 
After the parent or guardian signs the Informed Consent Form 
(ICF), all inclusion/ exclusion criteria will be checked for eligibility. 
A complete medical history and physical examination will be 
performed. 
Within 24 hours of the screening procedures, eligible infants will 
be randomly assigned to one of the three treatment groups. 
Treatment procedure 
During the treatment period, the infants will receive study medication 
with their enteral feeding (own mother's milk (OMM), donor breast 
milk (DBM), or infant formula) until discharge from the hospital or up 
to 28 days, whichever occurs first. The infant will not be treated more 
than 28 days. During the 28-day treatment period, the investigator 
will evaluate the infant for discharge or readiness for discharge from 
hospital, whichever occurs first. 
The powder will be administered preferably with all daily enteral 
feedings, but at least four times each day at enteral 
feedings.Commencement of the treatment period for infants who 
are fed solely on OMM should not begin within the first 72 hours 
post birth. 
Follow up period: 
The infants will return to the clinical site for a follow-up visit at 3 
months, 12 months, and 24 months corrected age. 
Baseline safety assessment will be performed during the screening 
period and throughout the study (see Table 1): 
1. Physical examination (PE) 
2. Blood chemistry and haematology 
3. Vital signs 
During the treatment period, adverse events (AEs), PE, and vital signs 
will be assessed and recorded in the source documentation and 
electronic case report form (eCRF). These would include episodes of 
NEC, sepsis, meningitis, hypoglycemia and death. 
Monitoring of glucose levels will be performed during the treatment 
period. 
Approximately up to 40 sites worldwide (European countries, United 
States of America, Israel, and possibly other countries).

BACKGROUND AND RATIONALE 
5.1. General Introduction 
Preterm infants have an under-developed gastrointestinal (GI) tract due to an abrupt disruption of 
pregnancy. 
During an essential but short t imeframe, preterm infants can compensate for their 3rd 
trimester lost growth and development, at w hich t ime they are at high risk for intestinal malabsorption 
due to their malfunctioning GI tract and other complications. That leads preterm infants to dependency 
on prolonged parenteral nutrit ion support (1-3). 
Promoting EN intake at that sensit ive time frame leads to GI maturation and reduces dependence on 
parenteral nutrit ion (PN) with its associated morbidities and complications. Nutrients consumed enterally 
are better absorbed, enhancing vital organ development, improving infants' growth and development 
during the short w indow of opportunity for compensating lost third trimester growth (3).

Version 7 dated 10 May 2017 
Preterm infants who are born 29 to 32 weeks of gestational age find it very difficult to coordinate suckling, 
swallowing, and breathing regularly. Therefore, they are fed mostly by nasogastric tube (NGT) and as a 
result of their under-developed GI they are placed on PN for a prolonged period of time to avoid 
complications and growth retardation. Smaller preemies cannot perform suckling at all. A meta-analysis 
of 21 articles regarding PN in preterm infants showed that the relevant average gestational age for PN is 
below 32 weeks. Preemies 33 to 36 weeks can usually feed for themselves (2). 
Insulin is one of the biologically active factors in breast milk. During the first days of life, colostrum 
mother's milk contains higher levels of insulin and other bioactive components than mature maternal milk 
does. 
Accumulating evidence indicates that insulin determines important physiological effects on 
intestinal growth, cell maturation, and enzyme expression in several mammalian species (4, 5). 
The perinatal period is crit ical for human development. The brain of preterm infants, who are born 
generally with weight of less than 1,500g, is particularly vulnerable to under-nutrition. Enteral nutrition is 
of major importance for the growth and the development of the GI tract, which depends on the amount 
and composition of feeds. Thus, the goal in preterm infants is fast transition to EN and enable full enteral 
feeding as soon as possible (3). 
Term infants undergo rapid growth in the third trimester of pregnancy, receiving nutrition through the 
placenta and swallowed amniotic fluid with no need to expend calories for temperature regulation or gas 
exchange. Preterm infants miss out on much or all of the third trimester and thus have higher nutrit ional 
requirements on a per kilogram basis than term infants. Human milk nourishes the term infant who can 
tolerate large fluid volumes, whereas preterm infants are less tolerant of high fluid volumes (3). 
For these reasons, human milk usually requires fortification for nutritional adequacy in preterm infants. 
Human milk varies widely in the energy and protein content as well as in other key nutrients. Thus, 
supplementing human milk is a current practice at NICUs. 
A newborn infant's GI tract is naturally exposed to insulin by consuming own mother's milk present 
mainly in colostrum after birth. Importantly, in utero the GI tract is also exposed to insulin levels present 
in the amniotic fluid consumed by the fetus generating a constant flux of insulin stimulating the GI tract. 
As of week 26 gestational age, when skin keratinization is achieved (6), the fetus is exposed to the 
amniotic fluid ingredients such as insulin mainly through the GI tract at ~450 ml of amniotic fluid a day. 
Insulin levels in own mother's milk drop from 1,000-2500 µU/ ml to a ~ 50-90 µU/ ml after the colostrum 
period (48 hours post-delivery); levels are not significantly influenced by gestational age. Thus, just as 
human milk is supplemented with proteins and other key nutrients for preterm infants, Nutrinia proposes 
to supplement human milk with insulin. 
Own mother's milk contains nutritional ingredients as well as various peptides such as insulin. 
Observations on lactating dams and suckling rats have shown that milk-borne insulin is biologically active, 
and that immature enterocytes have an increased responsiveness to insulin (7). 
Shehadeh et al. have 
shown that human milk contains high concentrations of insulin and that insulin is hardly detectable in 
infant formulas (8, 9).

Insulin stimulates intestinal epithelial cell proliferation, and ileal lactase activity is increased when porcine 
insulin is added to newborn piglets' feedings (4, 10). Shulman, et al. demonstrated that enteral insulin 
administration may be of benefit in reducing feeding intolerance in preterm infants (11). Thus, orally 
administered insulin is expected to demonstrate a beneficial influence on gut development. 
The NTRA-2112 pow der is mixed with saline, preterm infant's formula, own mother's breast milk or 
pasteurized breast milk (donor breast milk) for enteral administration. Natural insulin activity level is lost 
in pasteurized breast milk and absent in formula. The final insulin concentration obtained with NTRA-2112 
in the infant's nutrition is physiological and within the range of known local gut exposure to insulin levels 
in amniotic fluid and own mother's milk. 
During the past decade neonatologists have made major efforts to reduce feeding intolerance and t ime to 
full enteral nutrition because of the importance of reducing complications and enhancing development of 
vital organs in preterm infants. Major efforts include the introduction of donor breast milk (DBM) as well 
as improvement of preterm infant formula composition and other supplementations to mother's milk. 
NTRA-2112 is aimed at further improving preterm infant progression to enteral autonomy, reducing risks 
and improving infant development in this crucial window of opportunity. 
Preliminary data in preterm infants receiving 4 IU/ kg/ day insulin enterally from 4 to 28 days of age, suggest 
that enteral insulin administration increases lactase activity and may be of benefit in reducing feeding 
intolerance without inducing hypoglycaemia or other adverse effects (11). 
The administration of insulin to preterm infants' enteral nutrit ion proposed in this study will allow 
assessment of the influence of insulin on gastrointestinal maturation and on blood levels of lipids and 
glucose. 
As described in the following paragraphs, administration of oral insulin to preterm infants, low birth weight 
infants, humans and animals, at concentrations up to 1,000 t imes higher than those proposed in this study, 
demonstrated the safety of oral insulin administration. 
Nutrinia conducted a Phase I safety study in 11 low birth weight healthy infants in tw o centers in Israel 
(INFOR 1). All eleven received NTRA-2112 for 4 months, as in the proposed study, administered within 
infant nutrition. No treatment related adverse events were observed in any of the 11 infants. The 
consumption of insulin did not cause hypoglecemia and did not stimulate the production of anti-insulin 
antibodies. 
Nutrinia also conducted an efficacy Phase I study designed as double-blind, randomized, placebocontrolled 
trial to compare NTRA-2112 to placebo on GI development when added to infants' nutrit ion (infant 
formula) (INFOSUP I). The primary evaluation of gastrointest inal maturation was the ability of the preterm 
infants to achieve full enteral feeding (150ml/kg/day). Other objectives included assessment of whether 
NTRA-2112 led to reduction in the number of days to discharge from the neonatal ward, measurements 
of weight gain, and assessment of safety. The insulin concentration administered for 28 days in the study 
was within the insulin concentration range present in low range maternal colostrum (400 µU/ ml) and as 
proposed for the current study. The study comprised eight preterm infants, gestational age: 26-33 weeks

BW: > 750g were recruited during the study. The gestational age was 27-31 weeks for the control group 
and 30-31 for the treatment group. Infants in the treatment group reached full enteral feeding earlier, 
gained more weight during the treatment period than the control group, were discharged on average 
earlier, and were free of central line nutrit ion (TPN) earlier. 
A Phase 11, multi-center, double-blind, randomized controlled clinical trial is currently being finalized in 
Israel (INFOSUP II). The study's objective w as to evaluate further the effect of NTRA-2112 on preterm 
infants' gastrointestinal maturation. Inclusion criteria included gestational age between 26 and 33 
weeks and birth weight~ 750g. NTRA-2112 effect on GI development is evaluated by number of days to 
reach full enteral feeds (150 ml/kg/ day). As in the proposed study, NTRA-2112 0.04 IU/ g is used to 
prepare a 400 µU/ ml solution of insulin for dosing over a 28-day period. The stock solution is added to 
standard formula or milk to administer to the infant. The analysed data constitute about 45% (n=33) of 
the planned sample size. The data set includes twins {10 pairs) and singleton births (6 in the control 
group and 7 in the treatment group). An interim study analysis demonstrated shorter time to reach full 
enteral feeding as compared to placebo as w ell as benefit on other efficacy parameters related to 
infants' growth. Interim analysis was performed for the group and separately for twins and singletons. 
Mixed model analysis showed no effect of birth (singleton or multiple) on outcome. No drug related 
adverse events have been reported in this study. 
5.2. Rationale and Justification for the Study 
Knowledge of the risks caused by preterm infants' underdeveloped GI tract is described above. Nutrinia 
developed NTRA-2112 to fulfil the important role of enhancing the preterm infant's capacity for absorption 
in the GI tract, and reduce intestinal intolerance and malabsorption, therefore reducing dependence on 
parenteral nutrit ional support, improving development of vital organs, and reducing catheter-associated 
bloodstream infections and other associated complications. 
A new born infant's GI tract is naturally exposed to insulin by consuming own mother's milk present mainly 
in colostrum after birth. Importantly, in utero the GI tract is also exposed to insulin levels present in the 
amniotic fluid consumed by the fetus generating a constant flux of insulin stimulating the GI tract. As of 
week 26 gestational age, when skin keratinization is achieved, the fetus is exposed to the amniotic fluid 
ingredients such as insulin mainly through the GI tract at "'450 m l of amniotic fluid a day (6). 
Thus, the choice of therapeutic dose levels for preterm infants should compensate for both intrauterine 
and extrauterine insulin exposure. Moreover, average colostrum insulin content suffices for stimulation 
of a term infant's GI for enteral/oral feeding, w hile the preterm infant GI tissue takes several weeks to 
compensate for the disruption of pregnancy and critical intrauterine GI development occurring at the last 
trimester of pregnancy (Investigator's Brochure Section 1.6). 
Although human milk is recommended for preterm infants, it does not provide optimal nutrit ion by itself. 
The growth and neurodevelopmental needs of the preterm infants are best met by appropriate 
fortification of enteral nutrition including own mother's milk. Moreover, mothers of preterm infants 
produce only a few drops of colostrum at each expression for the first 24-48 hours after birth; 
consequently, OMM is a poor provider of essential nutrients and bioactive proteins (such as insulin).

Version 7 dated 10 May 2017 
Roughly three days after delivery, the insulin levels in OMM drop from 1,000-2500 µU/ ml to ~soµU/ ml. 
Thus, similar to way human milk is supplemented with proteins and other key nutrients for preterm 
infants, Nutrinia proposes to supplement human milk with insulin. Infant's formula, DBM, or a mix of these 
sources needs to be compensated, as natural Insulin activity level is lost in pasteurized breast milk and 
absent in formula. 
Tw o dose levels will be assessed versus placebo: 
* 
NTRA-2112 Dose level 12 : 0.04 IU/ g powder formulation (0.5-g stick pack) is reconstituted to 
achieve 400 µU/ ml of planned daily enteral feeds 
* 
NTRA-2112 Dose level 23: 0.2 IU/ g powder formulation (0.5-g stick pack) is reconstituted to achieve 
2000 µU/ ml of planned daily enteral feeds 
The choice of the tw o dose levels is based on safety profiles and evidence of efficacy demonstrated in five 
independent clinical trials and several non-clinical studies. 
The dose levels, w ere selected within the range of known local gut exposure to insulin levels in amniotic 
fluid and own mother's milk to compensate for physiological intestinal insulin exposure. Both dose 
levels have been demonstrated safe in preclinical trials. NTRA-2112 Dose level 1 was assessed in 
previous clinical studies and was found to be safe and efficacious in the proposed patient population. 
Nutrinia and its scientific advisors have conducted clinical trials in preterm infants, small for gestational 
age infants, and short bowel infants and children with three dose levels (investigator's Brochure Section 
4) of orally administered insulin in the course of five separate clinical trials. In these studies, the dose of 
insulin ranged from 0.01 U/ kg/ day to 4.0 U/ kg/ day. These doses correspond to an equivalent dose of 90 
to 4,000 µU/ m l. As previously described these doses are equivalent or higher than the current target dose 
of NTRA-2112 which would correspond to an exposure or 400 or 2000 µU/ ml. Further supporting the dose 
selection is the duration of treatment (28 days) in 4 of the 5 studies. The duration in study INFOR 1 w as 4 
months, while the other clinical trials durations were 28 days. These durations, coupled with the dose 
described above, support the safe administration of NTRA-2112. 
In summary, the accumulated clinical safety and efficacy results in preterm infants dosed with similar and 
significantly higher orally-administered insulin levels as compared to the current proposed study strongly 
support further clinical development of NTRA-2112 as a path to reduce intestinal malabsorption in preterm 
infants. 
2 NTRA-2112 dose level 1 was used in the Phase I & II trials with NTRA-2112 equivalent to 
0.04 U/kg/day (based on 1 kg body weight and 100 ml daily enteral nutrition). 
3 equivale nt to 0.2 U/kg/day (based on 1 kg body weight and 100 ml daily ente ral nutrition)

AEs considered related to the trial medication as judged by a medically qualified investigator and 
all SAEs (related and unrelated to trial medication) will be followed until resolution. Resolution is 
defined as the return to baseline status or stabilization of the condit ion when investigator deems 
further observations or examinations no longer required as medically indicated.

If the event causing the withdrawal occurred betw een days 28 and the final study visit (follow -up 
visit ), and the event was designated as not product-related, the study withdrawal will be recorded

9.5.2. Premature Study Termination 
The study subjects are expected to experience many adverse events, including severe adverse events 
related to premature birth, invasive surgery, or other underlying conditions including potential to 
develop NEC. NEC is characterized by the sudden onset of gastrointestinal distress that may include 
symptoms such as vomit ing, abdominal distention, bloody stools, or dilated loops of bowel that leads to 
cessation of enteral feedings. Therefore, all safety concerns potentially leading to study termination will 
be referred to the Data Monitoring Committee (DMC), w hich is responsible for a formal assessment of 
the safety of the study. This Board will propose the appropriate course of action to the Sponsor. 
Individual Events: 
Any of the following individual events would be referred by the study Medical Monitor to the DMC 
chairman for review, who may decide that the events warrant a full DMC review. The DMC w ill review 
these events unblinded to fully evaluate the potential risk to subjects in this trial. Given this is a blinded 
trial, the DMC review is required to consider if the events, both serious and related non-serious events, 
are occurring more frequently in the active arms and to judge whether there is a meaningful likelihood 
that these events are drug-related. The DMC may recommend to the Sponsor to stop the study, or any 
portion of it, at any t ime for safety reasons on the basis of their review. Individual events that may 
trigger a DMC review based on individual cases: 
• 
Two or more cases of Grade 3 or greater allergic reactions or anaphylaxis, that the investigator 
deems as possibly related to study medication; 
• 
Any case of autoimmune disease associated with neutralizing antibodies to insulin and w here 
other related causes, such as Type I diabetes, are ruled out; 
• 
Two or more cases of persistent Grade 3 or greater hypoglycemia that is non-responsive to 
treatment within 72-hours and reoccurs after temporary discontinuation of study medication and 
re-challenged. 
Further, the Medical Monitor will be responsible for review of all reported SAEs in an ongoing manner. 
Any SAE that is deemed potentially related to study medication, or of particular concern by the Medical 
Monitor, will also be sent to the DMC Chairman for review w ithin 15 days. The DMC Chairman may 
decide to bring any individual SAE event that may be related and of concern to the full DMC for review.

Clinical Trial Protocol: FIT-04 
Version 7 dated 10 May 2017 
The Medical Monitor and DMC will review aggregate safety data in an ongoing manner, at DMC meetings 
w hich will be held approximately each 4 months throughout the trial. The Medical Monitor will remain 
blinded to treatment assignment for cumulative data at all t imes, but may refer any safety concerns 
based on review of safety data to the DMC for further evaluation. The DMC will receive unblinded safety 
data summaries from an independent statistician that is assigned to prepare the unblinded study reports 
for all subjects at each DMC meeting. The DMC statistician will compare the event rates for AEs 
between the groups and the probability that the groups differ in the frequency of events. If there are 
differences in Grade 3 or higher adverse events that differ materially betw een the active arms and/ or 
placebo, and that may be attributable to study medication based on the mechanism of action of the 
drug, the DMC has the option to recommend that the Sponsor stop the study, or modify the protocol for 
safety reasons. 
The study may also be prematurely terminated for administrative reasons, ethical considerations, at the 
request of local regulatory agencies, or for any other reason the Sponsor deems appropriate.

INVESTIGATIONAL MEDICINAL PRODUCT (IMP) 
10.1. 
IMP Description 
The study medications include an active formulation designated NTRA-2112 with human insulin in 2 
different doses as the active pharmaceutical ingredient and a placebo formulation. 
The placebo 
formulation consists of the same inactive ingredients as NTRA-2112. 
NTRA-2112 is incorporated into preterm infant's formula, own mother's milk and pasteurized breast milk 
(donor breast milk) for enteral administration. NTRA-2112 may also be reconstituted with normal (0.9% 
NaCl) or half normal saline (0.45% NaCl) for enteral administration, as described in the pharmacy manual. 
Natural insulin activity level is lost in pasteurized breast milk and absent in formula. The final insulin 
concentration obtained with NTRA-2112 in the infant's nutrition is physiological and within the range 
present in human breast milk and colostrum.

10.5. 
Treatment Compliance 
The compliance check will be based on the number of meals to which NTRA-2112 or placebo was added 
(i.e., actually taken) to the infant's planned daily enteral nutrition. Missed doses should not be replaced 
or added. 
Compliance should be emphasised; however, randomized infants will not be discontinued for lack of 
compliance. 
Full or partial dose interruptions are permitted at the Investigator's discretion; interruptions should last no 
longer than 3 consecutive days. 
10.6. 
Packaging and Labelling 
The IMP (NTRA-2112 and Placebo) is packed in stick packs. Secondary carton packaging is provided with 
200 stick packs for each infant, which genera lly is the sufficient amount of stick packs for the entire 
treatment period. Each infant will have a designated carton package of study medication. In case of a 
need, an unscheduled re-supply of additional IMP kit can be assigned to the infant. 
All labelling complies with Volume 4. Good Manufacturing Practices, Annex 13. Manufacture of 
investigational medicinal products, July 2010. 
10.7. 
Storage of Study Medication 
Study medication will be stored at room temperature in the pharmacy or in the neonatal intensive care 
unit, depending on where the institution stores medication and prepared medication for the study infants. 
Further instructions are available in the Pharmacy Manual. 
10.8. 
Accountability of the Study Medication 
Upon receipt of study drugs, the Investigator (or designee) will conduct an inventory count of the supplies. 
The Investigator will retain a copy of this inventory at the site and provide a copy to the study monitor. 
The study monitor may check the inventory of supplies at the study site at any t ime during the study. 
Drug supplies, which the sponsor will provide, must be kept in a secure, limited access storage area under 
the storage conditions defined by the sponsor (see Pharmacy Manual). 
The Investigator, pharmacist and/or investigational drug storage manager will receive the investigational 
drugs when a ll country-specific required approvals are in place and all required country-specific essential 
documents are provided to Nutrinia or its designee. 
The Investigator, pharmacist and/or investigational drug storage manager must maintain records of the 
product's delivery to the trial site, the inventory at the site, the use by each infant, and the return to the 
Sponsor of unused or partia lly used product. These records will include dates, quantities, batch/serial 
numbers, re-test ('use by') dates, and the unique kit numbers assigned to the investigational product and

w ill maintain records that document adequately that the infants were provided the doses specified by the 
protocol, plus kits assigned by randomization system and reconcile all investigational products received 
from the Sponsor. At the time of return to the Sponsor, the Investigator, pharmacist and/ or investigational 
drug storage manager must verify that all unused or partially used drug supplies have been returned and 
that no remaining supplies are in the Investigator's possession. 
The study monitor is responsible for ensuring that the Investigator (or designee) has correctly documented 
the dispensing of study drugs on the dispensing log. The st udy monitor will perform an inventory of study 
drugs at routine monitoring visits and at the closeout visit to the site. 
11. SAFETY MEASURMENTS

Definitions 
Adverse Event (AE) 
Any untoward medical occurrence in a clinical investigation of a subject 
administered a pharmaceutical product (either test product or cont rol 
product) and that does not necessarily have a causal relationship w ith 
the t reatment. 
An AE is therefore any unfavorable and unintended sign, symptom, or 
disease temporally associated wit h the use of an investigational 
(medicinal) product or other protocol-imposed intervention, regardless 
of attribution, i.e., whether or not related to t hat investigational 
(medicinal) product. An AE may include intercurrent illnesses or injuries 
that represent an exacerbation (increase in frequency, severity, or 
specificity) of pre-existing conditions (e.g., worsening of asthma). 
A laboratory abnormality will be reported on the "Adverse Event" case 
report form only if the investigators considered it clinically significant, or 
if it is associated w ith clinical sequelae or requires therapeutic 
intervention

Serious Adverse Event 
A serious adverse event is any untoward medical occurrence that: 
(SAE) 
. results in death 
. is life-threatening 
. requires inpatient hospitalisation or prolongation of existing 
hospitalisation 
. results in persistent or significant disability/incapacity 
Other 'important medical events' may also be considered serious if they 
jeopardise the study infant or require an intervention to prevent one of 
the above consequences. 
NOTE: The term "life-threatening" in the definition of "serious" refers to 
an event in which the infant was at risk of death at the time of the event; 
it does not refer to an event that hypothetically might have caused death 
if it were more severe. 
Serious Adverse Reaction 
An adverse event that is both serious and, in the opinion of the reporting 
(SAR) 
Investigator, believed with reasonable probability to be due to one of 
the t rial treatments, based on the information provided. 
Suspected Unexpected 
A serious adverse reaction, the nature and severity of w hich is not 
Serious Adverse Reaction 
consistent with the information about the medicinal product in question

an "Adverse Event" . 
A clinical event, including a laboratory test abnormality, with a reasonable 
t ime sequence to administration of the drug, but that could also be explained 
Possible 
by concurrent disease or other drugs or chemicals. 
Information on drug 
withdrawal may be lacking or unclear. For the purpose of this protocol, an

11.3. 
Collecting, Recording and Reporting of Adverse Events and Serious Adverse Events 
Treatment-emergent AEs are events that are not present at screening, or if present at screening, have 
worsened in severity or frequency. 
Data regarding all treatment-emergent AEs will be collected in this study and recorded in the source 
documentation and in the eCRF, whether or not the event is attributed to trial medication. Pre-treatment 
emergent events w ill not be considered as AE and will be recorded as medical history. 
Adverse event monitoring will be captured throughout the study from Day 1 (init iation of dosing) until the 
final study visit (follow-up visit). 
AEs and SAEs w ill be evaluated daily during the treatment period. An additional safety evaluation w ill be 
performed at discharge or end of treatment and at final study visit (follow-up visit). 
The follow ing information will be recorded: description, date of onset and end date, severity, assessment 
of relatedness to trial medication, other suspect drug or device, and action taken. Follow-up information 
should be provided as necessary. The investigator will assess AEs for severity, for relationship to the study 
drug, and as to whether the event meets one or more of the definit ions of an SAE. 
AEs w ill be graded on a 5-point scale (mild, moderate, severe, life-threatening, and death) and reported as 
indicated in the source documentation and in the eCRF. Severity of such an AE is defined as follows:

Death 
I Outcome of AE was death 
AEs that are not described on the CTCAE v 4.03 will be graded using the scale in Table 2. 
In order to classify adverse events and diseases, the sponsor or designee will use the Medical Dictionary 
for Regulatory Activities (MedDRA) to assign preferred terms to the original terms entered in the eCRF. 
AEs considered related to the trial medication as judged by a medically qualified investigator and all SAEs 
(related and unrelated to trial medication) must be followed until resolution. Resolution is defined as the 
return to baseline status or stabilization of the condition with the expectation that it will remain chronic. 
The Investigator will use clinical judgment to decide whether or not an AE is of sufficient severity to require 
the study infant's removal from treatment. A participant's parents or legal guardian may also voluntarily 
withdraw from treatment for w hat he or she perceives as an intolerable AE. If either of these occurs, the 
infant must undergo an end of trial assessment and be given appropriate care under medical supervision 
until symptoms cease, or the condition becomes stable. 
All SAEs must be reported to the Sponsor by the Investigator, study coordinator, other designated study 
personnel, or clinical research associate within 24 hours of notification of the SAE for any related SAEs and 
any SAE resulted in death (related or unrelated), and within 48 hours for SAEs unrelated to the 
investigational product, other than death. To report such events, an SAE form must be completed by the 
Investigator and/ or designee and sent by email or fax with relevant information. 
The Investigator or designee must provide further information on the SAE as soon as it is available. This 
should include a copy of the completed SAE form, and any other information that will assist the 
understanding of the event. Significant new information on ongoing SAEs should be provided promptly as 
a follow-up. 
The Investigator and/ or designee also must report all SAEs promptly to the appropriate Independent ethics 
committee (IEC) / Institutional Review Board {IRB) as required by the institution.

Safety M onitoring Plan 
The Investigator is responsible for the classification of adverse events and together w ith the Sponsor for 
the ongoing safety evaluation of the clinical investigation. 
The sponsor shall: 
• 
Set up a Data Monitoring Committee - An independent DMC will review safety data and will make 
recommendations whether to continue or terminate the study. The DMC analyses and operations 
will be formally separated from the sponsor, the investigators, and the Steering Committee. 
Details on the composition of the committee, its procedures, and its interactions are provided in 
a separate DMC Charter. 
• 
Review the investigator's assessment of all adverse events and determine and document in w riting 
their seriousness and relationship to the study medication; in case of disagreement between the 
sponsor and one or more principal investigator, the sponsor shall communicate both opinions to 
the IEC/ IRB and the national regulatory authorit ies, if required. 
• 
Report or ensure the reporting to the IEC/ IRB by the Pis of all serious adverse events according to 
timelines specified in Section 11.3. 
• 
Report to regulatory authorities, within the required time period, all serious adverse events, if 
required by national regulations. 
Inform all Pis in w riting of all the serious adverse events at all investigation sites that have been 
reported to the sponsor, and ensure that the Pis report them to their IEC/ IRB, if required by 
national regulations; this information shall be sent to all Pis w ithin a time frame established based 
on the perceived risk. 
• 
Ensure that the IEC/ IRB and the regulatory authorities are informed of significant new information 
about the clinical investigation. 
In case of a serious adverse event, determine w hether the risk analysis needs to be updated and 
assess whether corrective or preventive action is required.

SAMPLE SIZE AND STATISTICAL METHODS 
12.1. 
Overview 
This trial aims to assess the efficacy and safety of 2 doses of NTRA-2112 as compared to placebo on 
intestinal malabsorption in preterm infants. The primary efficacy w ill be assessed by comparing the 
distributions of days to full enteral feeding (NFE) between active doses and placebo. Safety w ill be assessed 
by adverse events and safety measurements. 
12.1.1. Design Considerations 
This mult i-center, double-blind, randomized, placebo-controlled study will compare preterm infants 
receiving one of 2 doses of NTRA-2112 to those receiving placebo. Infants will be randomized to treatment 
A or 8 or C using a 1:1:1 ratio. Randomization will be blocked and stratified by tw o levels of gestational 
age: 
26+0 to 28+6 wks 
• 
29+0 to 32+0 weeks

The block size will remain blinded to the Sponsor and the Investigators. 
This study allows inclusion of both fraternal and identical twins. For ethical reasons, each twin pair (if both 
are eligible for the study) will be randomized into the same treatment arm. The decision was made after 
consultation with physicians who assert that parents should not be put in a position in which one of their 
twins receives placebo while the other receives NTRA-2112. Because of the possible dependency between 
the outcomes for twins, if both are eligible for the study, the primary analysis will include only the 
firstborn. 6 If only one twin is eligible, then that twin (whether first- or second-born) will be included in the 
primary analysis. 
While only one of the twins will be included in the trial's full analysis set (FAS), throughout the trial period 
all eligible twins will receive the treatment to which they were assigned. The safety analyses will include 
all infants receiving study treatment, whether or not they are members of the FAS. Some additional 
efficacy analyses will include both participating twins and some will include only the second born of the 
participating twins. 
The planned trial is mult i-center; it will be comprised of a large population of infants including twins and 
those given different types of feeding regimens (i.e., OMM, DBM only, formula, combinations). Nutrinia 
knows of no similar study that has been conducted in such a wide-ranging population. The best estimate 
of within-group variation, which is crit ical for correctly computing study power, is based on Nutrinia's 
INFOSUP II - Phase II study with a narrower population. For this current trial, it is important to assess the 
accuracy of our assumption regarding within-group variation because an underestimation of variance has 
the potential to reduce study power substantially. Consequently, a sample size re-estimation procedure 
will be used at the time of the interim futility analysis. The sample size may be increased if the standard 
deviation is at least 5% larger than assumed in the protocol. 
The same statistician who will prepare the analysis for the interim futility calculation will compute the 
average within-group standard deviation; this person will not be involved in any other aspect of the trial. 
The Statistical Analysis Plan, which will be written prior to the futility analysis, will describe in detail the 
method for the estimation of standard deviation and the methods to be used to ensure blinding of study 
statisticians to all information apart from the updated sample size. 
This trial has one primary and one key secondary endpoint. The key secondary endpoint will be formally 
tested only if the data show statistically significant benefit on the primary endpoint. The study is

comparing each of two doses to placebo; a Bonferroni approach will be used to adjust for the two tests of 
the two doses NTRA-2112. 
The key secondary endpoint in this trial is number of days to discharge from the hospital. The decision to 
discharge a preterm newborn from the hospital is based on standard of care and hospital policies, which 
may also include social considerations7• Thus, the key secondary endpoint refers to actual discharge from 
the hospital. Infants not reaching NRD (number of days to discharge from the hospital) due to death or 
complications will, as noted in the preceding paragraph, be excluded from the primary analyses. 
12.2. 
Analysis Sets 
12.2.1. Safety Analysis Set 
The safety analysis set will consist of all infants in w hom any study drug- placebo or NTRA-2112- was 
initiated. If both members of a pair of twins are part icipating in the study, the safety analysis set will 
include both. 
12.2.2. Full Analysis Set (Intention-to-treat) 
The Full Analysis Set will consist of all randomized singletons and, for twins who both participate in the 
study, only the first born. 
12.2.3. Per-Protocol Analysis Sets 
Instead of defining a Per-Protocol (PP) analysis set, modern methods of analysis of PP data that separate 
the reasons for noncompliance from the effect of study drug will be used as per, for example, Robins 
(1989)(12). 
12.2.4. Safety 
Serious adverse events and adverse events occurring at any t ime during the trial or follow-up will be listed 
and summarized. 
The incidence of (1) NEC and (2) death w ill be compared betw een the t reatment groups. 
Safety assessments will include: 
• 
Length of exposure to study medication 
Physical examination and vital signs 
Blood chemistry and haematology 
7 For example, one of a twin pair may remain in the hospital despite readiness for discharge until his/her sibling is 
also ready for discharge, so that both can be discharged at the same time.

Sample Size Considerations 
Presentation of sample size is based on the hypothesis that NFE in either treatment group is shorter than 
in the placebo group. Based on limited historical data (phase 2), the conservative mean is 8.0 days for the 
placebo group and 6.6 days for each of the 2 active dose groups. This assumes a standard deviation of 3.5 
days for each group. 
The analysis will be based on a nonparametric test. The NFEs for each infant in the FAS will be ranked from 
shortest time (the best outcome) to longest time. Infants who do not achieve EN because they experience 
NEC will be assigned the next set of ranks; all the infants experiencing NEC will be ranked in terms of their 
time to NEC (the earlier the worse) and will be assigned ranks one greater than the rank of the longest 
time to achieve NFEs. All infants who die will be assigned the next set of ranks, again with the earliest 
deaths assigned the worst rank. Thus, each infant who has achieved EN or w ho has died or suffered NEC 
will have an observed rank. 
Study Infants will be randomized by center and by gestational age group. The statistical analysis will stratify 
the infants by gestational age group and region (United States and Europe), but not by center. Because 
the analysis will be based on ranks, a Van Elteren test will be used to compare NTRA-2112 to placebo. To 
calculate sample size, an independent groups t-test for 85% power to account for the reduced power of 
the non-parametric test was used (i.e., expect that at-test with 85% power to have at least 80% w hen the 
Van Elteren test is applied). A 2.5% significance level to account for 2 dose comparisons to placebo was 
used. These calculations give N = 136 infants per group. To account for the reduction in power caused by 
potential missing data, the sample size was increased to 150 per group or a total sample size of 450. 
Note: The sample size provided in this section relates only to those infants included in the FAS; however, 
the total number of infants treated with NTRA or placebo may be as high as 530, depending on how many 
of the infants in the study are pairs of twins. As described above, the FAS will include only the first born 
infant in a participating pair of twins. The second born sibling will be included in safety analyses and some 
supplementary efficacy analyses.

Statistical Analysis 
This section briefly describes the statistical analysis planned for the study. A full Statistical Analysis Plan 
(SAP), to be w ritten prior to the futility analysis, will describe the methodology in detail. Should the 
methods in SAP differ from methods in this section, the methods in the SAP will take precedence.

Clinical Trial Protocol: FIT-04 
Version 7 dated 10 May 2017 
Statistical methodology will be consistent w ith ICH and other regulatory guidelines as well as general 
principles of rigorous statistics. 
12.4.1. Overview 
Data listings by infant will be provided. 
The data w ill be summarized in tables listing the mean, standard deviation median, 25th and 75th 
percentiles, minimum, maximum for continuous data, or in tables presenting counts and percentages. 
Tables will be presented by study arm and overall. "Time-to" data w ill be described by survival curves. 
All statistical analyses will be performed and data appendixes will be created using the SASe system or 
other validated softw are. 
12.4.2. Disposition of Study Infants 
Disposit ion of study infants w ill be reported for the FAS and the safety analysis set. Tables will present the 
number of infants enrolled, exposed, prematurely terminated, and completed will be summarized by 
treatment group and overall. A list of dropouts will show the reason for and t ime of discontinuation. 
12.4.3. Baseline Comparability 
Demographic and baseline clinical variables will be presented for infants in each treatment arms using 
tables and figures along w ith descriptive statistics. Treatment groups w ill be compared to evaluate the 
balance achieved by randomisation. Observed differences between the groups, should there be any, will 
be interpreted for their clinical significance and their potential use as covariates in sensit ivity analyses of 
efficacy endpoints. 
12.4.4. Safety 
The safety analyses w ill be descriptive and narrative in nature, w ith SAEs and AEs coded using MedDRA 
and tabulated by body system, preferred term, treatment group, severity, and relation to IMP. Descriptive 
statistics will be provided by treatment group as appropriate. 
12.4.S. Primary Efficacy Endpoint 
The FAS will be used to test the primary efficacy endpoint. 
The primary efficacy analyses (one for each dose) will test the following null and alternative hypotheses: 
Ho: The distribution of the number of days to full enteral feeding is the same in the treated and 
the placebo groups. 
H1: The distribution of the number of days to full enteral feeding differs in the treated and the 
placebo groups.

Clinical Trial Protocol: FIT-04 
Version 7 dated 10 May 2017 
The ranks for any missing values will be calculated using mult iple imputation; the SAP will describe the 
methods in detail. 
The Van Elteren Test will be used for the primary efficacy analysis with data stratified by two Gestational 
age (GA) strata and two regions (North America and Europe). For each dose, the test will be performed 
with a Bonferroni correction, which will maintain the overall two-sided Type I error rate at 0.05. 
The study will have shown benefit of NTRA-2112 if the null hypothesis for either tested dose is rejected 
and NFE is shorter for NTRA-2112 than for placebo. 
12.4.6. Key Secondary Endpoint 
The FAS will be used to test the key secondary efficacy endpoint. 
The key secondary endpoint will be tested only if the primary efficacy analysis shows superiority. For each 
dose that shows superiority for the primary efficacy endpoint, the following hypothesis will be tested: 
Ho: The distribution of the number of days to NRD is the same in the treated and the placebo 
groups. 
H1: The distribution of the number of days to NRD differs in the treated and the placebo groups. 
where NRD = number of days to discharge from t he hospital. 
The ranks for any missing values will be calculated using mult iple imputation; the SAP will describe the 
methods in detail. 
Testing of the key secondary endpoint will be by the Van Elteren test, stratified by region (North America 
and Europe) with a threshold for statistical significance of P<0.025. 
The data will have shown benefit on the key secondary outcome for either dose for which the null 
hypothesis is rejected and the NRD is shorter for NTRA-2112 than for placebo. 
12.4.7. Other Secondary Endpoints 
The other secondary endpoints will be tested in the FAS. For each of these other endpoints, the two-sided 
Type I error rate will be 0.025 for each dose. Statistical testing of these other secondary endpoints will be 
considered exploratory and will not control for Type I error rate. The SAP will describe the methods used 
for these endpoints including the approaches planned for missing data. Long term follow -up data at 12 
and 24 months will be summarised descriptively. Full details will be given in the SAP. 
12.4.8. Analyses of Predictor Variables 
Effect of covariates: The effect on the primary and key secondary outcomes of the following variables will 
be assessed: 
• 
GA 
• 
Birth weight

feeding 
5. Donor breast milk and formula, in any combination of proportions, to full enteral

12.4.9. Sensitivity Analysis: Missing Values 
The following sensitivity analyses will be conducted on the primary and key secondary endpoints to explore 
the effect of these missing values: 
• 
Worst reasonable case analysis: Infants in an NTRA-2112 group with a missing rank will be 
assigned the median rank in the placebo group and infants in the placebo group with a missing 
rank will be assigned the median rank in the combined NTRA-2112. 
Best reasonable case analysis: Infants in an NTRA-2112 group with a missing rank will be assigned 
the median rank in the respective NTRA-2112 group and infants in the placebo group with a 
missing rank will be assigned the median rank in the placebo group. 
• 
Tipping point analysis: Infants in any group with a missing rank will be assigned varying ranks to 
find the point at which the results reverse from favoring one treatment group to the other. 
Survival ("time-to-event") analysis: a log rank test will be performed to compare t ime-to-FEF. In 
this analysis, infants who experience NEC will be assigned censoring times of 29 days and infants 
who die will be assigned censoring t imes of 30 days. Any other infants who withdraw from the 
study early will be considered censored at the day of their last participation in the study (unless 
they have already achieved FEF in which case they will not be censored. 
12.4.10. 
Sensitivity Analysis: The second born Twin 
Several analyses will be performed to include the second born twin. 
One analysis will repeat test the primary and key secondary endpoints replacing the first born twin by the 
second born twin.

Another approach will be a hierarchical mixed model that includes both twins in a way that accounts for 
the possible correlation between them. The SAP will describe in detail the method to be used, including 
the approach to handle deaths and cases of NEC. 
12.4.11. 
Sensitivity Analysis: The PP Set 
Many physicians are interested in the effect of an intervention on patients who actua lly take the drug. The 
typical approach is to analyze the data in a so-ca lled PP set of data. These analyses are prone to serious 
bias. Nutrinia plans to use modern methods of analysis of PP data that disentangle the reasons for 
noncompliance from the effect of study drug.(12). The SAP will describe these analyses. 
12.4.12. 
Interim Futility Analysis 
The study will include an interim futility analysis as defined in the SAP. For the futility analysis, the 
condit ional power of showing statistically significant evidence of benefit on the primary endpoint will be 
calculated for each dose group. If the conditional power is less than 20% in either dose, continuing to 
enter infants in that dose group will be considered statistically futile. 
An independent statistician will perform the futility analysis. This statistician will not be involved in the 
preparation of the statistical analysis plan or in other aspects of the trial. The statistical analysis performed 
during the futility interim look will be presented as defined in the SAP to an independent Data Monitoring 
Committee (DMC), which will review the results and make a recommendation regarding continuing the 
study, stopping the study, or discontinuing recruitment into one dose group. The DMC will base its 
recommendation on trial continuation on the tota lity of evidence available to it, rather than only on the 
statistical futility criterion. Because the only reason to recommend stopping the study, or stopping one 
dose, is futility (or safety) and not efficacy, this analysis does not compromise the Type I error rate. 
The Sponsor will be blinded to a ll efficacy and safety data. Only the fina l DMC recommendation will be 
provided to the Sponsor.

DATA MANAGEMENT 
13.1. 
Source Data 
Source documents are the documents where data are first recorded, and from which participants' eCRF 
data are obtained. These include, but are not limited to, hospital records (from which medical history and 
previous and concurrent medication may be summarised into the eCRF), clinical and office charts, 
laboratory and pharmacy records, diaries, radiographs, and correspondence. 
The Investigator will maintain adequate and accurate source documents designed to record all 
observations and other pertinent data for each subject treated with the study drug. The Investigator will 
make a ll safety assessments (AEs, vital signs, results from physical examinations, and laboratory tests) on 
an ongoing basis. The Investigator is responsible for all information collected on subjects enrolled in this 
study. All data collected during the course of this study must be reviewed and verified for completeness 
and accuracy by the Investigator. 
CONFIDENTIAL 
Page 54 of 69

Nutrinia 
Clinical Trial Protocol: FIT-04 
Version 7 dated 10 May 2017 
Study personnel at each site will enter data from source documents corresponding to a subject's visit into 
the protocol-specific eCRF when the information corresponding to that visit is available. For all entries into 
the eCRF that are not source electronic data, the data entries must be supported by original source 
documentation (e.g., laboratory reports, medical records) maintained at the investigational site. 
If a subject is lost to follow-up, (i.e., fails to return for scheduled visits) every reasonable effort must be 
made to contact the subject's parent or guardian in order to determine why the subject failed to return. 
All actions taken in this regard will be documented and dated in the eCRF and source record. 
All documents will be stored safely in confidential conditions. On all trial-specific documents, other than 
the signed consent, the participant will be referred to by the trial participant number/code, not by name. 
13.2. 
Access to Data 
Direct access will be granted to authorised representatives from the Sponsor, host institution and the 
regulatory authorit ies to permit trial-related monitoring, audits, and inspections. 
13.3. 
Data Recording and Record Keeping 
An eCRF will be completed for each subject who is assigned a study number and signs and dates the 
studyapproved ICF. All trial data will be entered on eCRF, which is software for capturing and managing 
clinical trial data. The software supports Good Clinical Practice (GCP). It has an intuitive interface for 
enrolment, clinical data capture, validation, and query management. The software uses tools for data 
cleaning, clinical data management, site monitoring, and for overall system oversight, auditing, and 
reporting. The study infants will be identified by a unique trial specific number and/ or code in all 
databases. The name and any other identifying detail will NOT be included in any trial data electronic file. 
The investigator or a designee will be logging into the system and entering the data directly at the site. 
The entries made in the eCRF will be monitored by a Clinical Research Associate (CRA) for completeness 
and accuracy. Edit checks/ rules will be configured for identifying discrepancies. These discrepancies will 
be resolved by investigators or designee after logging into the system. If a correction is required for an 
eCRF data, the t ime and date stamps track the person entering or updating eCRF data and create an 
electronic audit trail. 
The investigator is required to electronica lly sign the eCRF at appropriate t ime intervals. The investigator's 
signature on the eCRF serves to certify that the data collected for each subject is accurate, complete and 
legible. A copy of the eCRF will remain at the study site at the completion of the study.

review completed eCRF and study documentation for accuracy and completeness, and protocol 
compliance. The monitor should assure that data captured in the eCRF is fully supported by the source 
documents. Clinical monitors will also ensure that all protocol requirements, applicable Food and Drug 
Administration (FDA) regulations (CFR Tit le 21 Parts 50, 56, and 312 and ICH Guidelines for GCP - E6), other 
requirements, and Investigator's obligations are being fulfilled. 
By signing this protocol, the Investigator grants permission to the Sponsor (or designee), and appropriate 
regulatory authorities to conduct on-site monitoring and/ or audit ing of all appropriate study 
documentation. 
Apart from assuming responsibility for the communication between the investigator and the Sponsor, the 
clinical monitor duties include: 
• 
On-site visits; and 
• 
Review of study documents and results. 
On-site monitoring visits include pre-study/qualification visits, initiation visits, interim monitoring visits, 
and a close-out visit at the end of the study. At the close of the study, the monitor w ill be required to make 
a final on-site visit to assure that all study data has been properly completed. 
Reports of on-site visits shall be made by the monitor and should include, as applicable, resolution of 
concerns and queries, completion of appropriate follow-up activit ies, completion of assigned tasks, and 
corrective actions. Monitoring visit follow -up letters will be sent to the site for filing and adherence.

The results of this study w ill be published under the direction of the Sponsor. Results will not be published 
w ithout prior review and approval by the Sponsor. 
15.6. 
Expenses and Benefits 
No complications are anticipated from feeding the infant with the study insulin-enriched oral nutrition. No 
evidence or scientific findings of long-term negative effects stemming from feeding preterm infants w ith 
the insulin-enriched nutrition have been noted. This is also true w hen administering higher concentrations 
of insulin than the quantity proposed in this trial. Nonetheless, the possibility of long-term effects on the 
creation of insulin antibodies or the prevention of diabetes cannot be ruled out. A study infant may 
experience a slight but insignificant drop in the blood sugar level. 
Should the trial show that insulin indeed speeds up the maturation of the digestive tract, a study infant 
treated w ith NTRA-2112 may reach full nutrit ion sooner than would have occurred had the infant not been 
in the trial. 
This would reduce the risks to preterm infants and may provide better growth and 
development. In addit ion, the infant w ill contribute to study a new medication that may help thousands 
of pre-term infants born each year and suffer from complications due to immature digestive system 
Nutrinia is responsible for managing the financing for the study. Nutrinia has signed a contract w ith the 
facilities where they will perform the trial w ith the study doctor. The participation of the infant in the 
study will not involve any costs and the infant's parent or guardian will not have to pay for the study drugs. 
16. 
RETENTION OF STUDY DOCUMENTS 
The Pl should retain records for all study infants, including eCRFs, all source documentation (containing 
evidence of study eligibility, history and physical findings, laboratory data, results of consultations, etc.) as 
well as IRB/IEC records and other regulatory documentation in a secure storage facility. The records should 
be accessible for inspection and copying by authorized authorities.

Clinical Trial Protocol: FIT-04 
Version 7 dated 10 May 2017 
Appendix E: Expected Complications Related to Premature Birth 
While not all premature babies experience complications, being born too early can cause short-term and 
long-term health problems for preemies. Generally, the earlier a baby is born, the higher the risk of 
complications. Birth weight plays an important role, too. 
Some problems may be apparent at birth, while others may not develop until later. 
Short-term complications 
In the first weeks, the complications of premature birth may include: 
• 
Breathing problems. A premature baby may have trouble breathing due to an immature respiratory 
system. If the baby's lungs lack surfactant -
a substance that allows the lungs to expand -
he or she may 
develop respiratory distress syndrome because the lungs can't expand and contract normally. 
Preemies may also develop chronic lung disease known as bronchopulmonary dysplasia. In addition, some 
preemies experience prolonged pauses in their breathing, known as apnea. 
• 
Heart problems. The most common heart problems premature babies experience are patent ductus 
arteriosus (PDA) and low blood pressure (hypotension). PDA is a persistent opening between two major 
blood vessels leading from the heart. 
While this heart defect often closes on its own, left untreated it can cause too much blood to flow through 
the heart and cause heart failure as well as other complications. Low blood pressure may require 
adjustments in intravenous fluids, medicines and sometimes blood transfusions. 
• 
Brain problems. The earlier a baby is born, the greater the risk of bleeding in the brain, known as an 
intraventricular hemorrhage. Most hemorrhages are mild and resolve with little short-term impact. But 
some babies may have larger brain bleeding w hich causes permanent brain injury. 
Larger brain bleeds may lead to fluid accumulation in the brain (hydrocephalus) over a number of weeks. 
Some babies who develop hydrocephalus will require an operation to relieve the fluid accumulation. 
• 
Temperature control problems. Premature babies can lose body heat rapidly; they do nott have the 
stored body fat of a full-term infant and they cannot generate enough heat to counteract w hat's lost 
through the surface of their bodies. If body temperature dips too low, hypothermia can result . 
Hypothermia in a preemie can lead to breathing problems and low blood sugar levels. In addit ion, a 
preemie may use up all of the energy gained from feedings just to stay warm, not to grow bigger. That is 
w hy smaller preemies require additional heat from a warmer or an incubator until they are larger and able 
to maintain body temperature w ithout assistance. 
• 
Gastrointestinal problems. Preemies are more likely to have immature gastrointestinal systems, leaving 
them predisposed to complications such as necrotizing enterocolitis (NEC). 
This potentially serious 
condition, in which the cells lining the bowel wall are injured, can occur in premature babies after they 
start feeding. Premature babies w ho receive only breast milk have a much lower risk of developing NEC. 
• 
Blood problems. Preemies are at risk of blood problems such as anemia and infant jaundice. Anemia is a 
common condition in which the body does not have enough red blood cells. While all newborns experience 
CONFIDENTIAL

; 
Nutrinia 
Clinical Trial Protocol: FIT-04 
Version 7 dated 10 May 2017 
a slow drop in red blood cell count during the first months of life, the decrease may be greater in preemies, 
especially if the baby has a lot of blood taken for lab tests. 
Infant jaundice is a yellow discoloration in a new born baby's skin and eyes that occurs because the baby's 
blood contains an excess of a yellow-colored pigment from the liver or red blood cells (bilirubin). 
• 
Metabolism problems. Premature babies often have problems with their metabolism. Some preemies 
may develop an abnormally low level of blood sugar (hypoglycemia). This can happen because preemies 
typically have smaller stores of glycogen (stored glucose) than do full-term babies and because preemies' 
immature livers have trouble converting stored glycogen into glucose. 
• 
Immune system problems. An underdeveloped immune system, common in premature babies, can lead 
to infection. Infection in a premature baby can quickly spread to the bloodstream causing sepsis, a 
lifethreatening complication. 
Long-term complications 
In the long term, premature birth may lead to these complications: 
• 
Cerebral palsy. Cerebral palsy is a disorder of movement, muscle tone or posture that can be caused by 
infect ion, inadequate blood flow or injury to a preemie's developing brain either during pregnancy or w hile 
the baby is still young and immature. 
• 
Impaired cognitive skills. Premature babies are more likely to lag behind their full-term counterparts on 
various developmental milestones. Upon school age, a child w ho w as born prematurely might be more 
likely to have learning disabilities. 
• 
Vision problems. Premature infants may develop retinopathy of prematurity, a disease that occurs when 
blood vessels swell and overgrow in the light-sensit ive layer of nerves at the back of the eye (retina). 
Sometimes the abnormal retinal vessels gradually scar the retina, pulling it out of position. When the 
retina is pulled away from the back of the eye, it is called retinal detachment, a condition that, if 
undetected, can impair vision and cause blindness. 
• 
Hearing problems. Premature babies are at increased risk of some degree of hearing loss. All babies will 
have their hearing checked before going home. 
• 
Dental problems. Preemies w ho have been critically ill are at increased risk of developing dental problems, 
such as delayed tooth eruption, tooth discoloration and improperly aligned teeth. 
• 
Behavioral and psychological problems. Children who experienced premature birth may be more likely 
than 
full-term 
infants 
to 
have 
certain 
behavioral 
or 
psychological 
problems, 
such 
as 
attentiondeficit/ hyperactivity disorder (ADHD). However, more recent research suggests that -
at least 
for late preterm babies -
the risk of ADHD may be the same as it is for children w ho were born at full 
term. 
• 
Chronic health issues. Premature babies are more likely to have chronic health issues -
some of w hich 
may require hospital care -
than are full-term infants. Infections, asthma and feeding problems are more 
likely to develop or persist. Premature infants are also at increased risk of sudden infant death syndrome 
(SIDS).

1 INTRODUCTION 
The purpose of this statistical analysis plan (SAP) is to describe the procedures and the 
statistical methods that will be used to analyze and report results for Protocol FIT-04. 
1.1 
STUDY OBJECTIVES 
1.1.1 Primary Objective 
To assess the efficacy of 2 doses of NTRA-2112 as compared to placebo on intestinal 
malabsorption in preterm infants as measured by the time to full enteral feeding. 
 
Achievement of enteral feeding will be regarded as the first of 3 consecutive days 
consumption of at least 150 ml/kg/day enteral feeding (EN). 
The three treatment groups are 
• Placebo 
• NTRA – 2112 400 (µIU Insulin/ml) 
• NTRA – 2112 2000 (µIU Insulin/ml) 
1.1.2 Secondary Objective 
Key secondary objective: 
To assess the effect of 2 doses of NTRA-2112 compared to placebo on the number of 
days to achieve discharge from hospital or readiness for discharge, whichever occurs 
first. 
 
Readiness for discharge from hospital is defined as achieving all of the below: 
• Infant weight ≥ 1800g  
• Stable body temperature  
Capable of oral feeding (reached full enteral feeding and not dependent on parenteral 
nutrition [PN]).  
 
Other secondary objectives:

• Infant weight ≥ 1800g 
• Stable body temperature 
• Capable of oral feeding (reached full enteral feeding and not dependent on PN) 
 
 Note: enteral feeding may also include tube feeds.

1.3 SUMMARY OF THE STUDY DESIGN 
1.3.1 General Study Design and Plan 
The study is a multi-center, double-blind, randomized, three-arm, parallel-group, 
placebo-controlled study to assess the efficacy and safety of NTRA-2112. 
 
Infants will be enrolled within 5 days from birth (at least 6 hours post birth and up to 120 
hours post birth) and will be treated for 28 days or until hospital discharge (whichever 
comes first). The study also includes a follow-up period up to 24 months corrected age. 
 
Full enteral feeding is defined as reaching 3 consecutive days in which the infant 
consumed at least 150 ml/kg/day of enteral nutrition. 
 
Enrolled infants will be under supervision at a NICU.

1.3.2 Randomization and Blinding 
Following screening procedures eligible infants will be randomly assigned to one of the 
three treatment groups in a 1:1:1 ratio. Randomization, stratified by the gestation age 
group, should take place as close as possible to treatment initiation and within 24 hours of 
confirmation of eligibility. 
 
Treatment should commence at postnatal age of up to and including Day 5 (up to 120 
hours post birth). 
 
Commencement of the treatment period for infants who are fed solely on own mother’s 
milk should not begin within the first 72 hours post birth. 
 
Randomization will be performed using random allocation generated by computer code. 
If both members of the twin pair are eligible to be included in the study at the same time, 
the firstborn will be randomized and the other sibling will be automatically allocated to 
the same treatment group as the firstborn sibling. 
 
If siblings are determined to be eligible for the study at different times, the sibling who is 
determined to be eligible for the study first will be randomized first (regardless of birth 
order), and the other sibling will be automatically allocated to the same treatment group. 
The assigned medication numbers (kit number) will be entered in the electronic case 
report form (eCRF), and the corresponding medication kit administered to the infant. 
 
It is assumed that in all cases when twins are both in the study, the first born will be the 
first one entered, and therefore the one who is randomized.  However, to avoid 
ambiguity, any reference in this SAP to “first born” is intended to mean the first entered 
(and therefore randomized) into the study.  Similarly, reference to “second born” is 
intended to mean the second twin entered (and who, therefore, is not randomized, but 
follows the treatment assignment of the twin who was first entered). 
 
In the event that unblinding of treatment allocation is necessary for emergency treatment, 
it is required that the investigator contact the Medical Monitor for the treatment 
allocation of the subject. Following discussion on the urgency and requirement for 
knowing the exact treatment, the Medical Monitor will determine whether to unblind the 
allocation and provide the treatment assignment to the Investigator (PI). All unblinding 
events must be reported to the Sponsor and/or Contract Research Organization (CRO) 
within current approved protocol requirements by the Investigator, study coordinator 
(other designated study personnel), or by the clinical research associate. 
 
1.3.3 Sample Size and Statistical Power Considerations 
Presentation of sample size is based on the hypothesis that NFE in either treatment group 
is shorter than in the placebo group. Based on limited historical data (Phase 2), the 


Protocol No: FIT-04 
Protocol Version: 7.0  
Statistical Analysis Plan V1.3

Confidential 
Page 15 of 40 
 
conservative mean is 8.0 days for the placebo group and 6.6 days for each of the 2 active 
dose groups. This assumes a standard deviation of 3.5 days for each group. 
 
The analysis will be based on a nonparametric test. The NFEs for each infant in the FAS 
will be ranked from shortest time (the best outcome) to longest time. Infants who do not 
achieve full enteral feeding and also experience necrotizing enterocolitis (NEC) will be 
assigned the next set of ranks; all the infants experiencing NEC will be ranked in terms of 
their time to NEC (the earlier the worse) and will be assigned ranks one greater than the 
rank of the longest time to achieve NFEs. All infants who do not achieve full enteral 
feeding and die will be assigned the next set of ranks, again with the earliest deaths 
assigned the largest (i.e. worst) rank. Thus, each infant who has achieved EN or who has 
died or suffered NEC will have a recorded rank. 
 
Randomization will be stratified by center and by gestational age group. The statistical 
analysis will stratify the infants by gestational age group and region (North America, 
Europe, and Israel), but not by center. Because the analysis will be based on ranks, a van 
Elteren test will be used to compare NTRA-2112 to placebo. To calculate sample size, an 
independent groups t-test for 85% power to account for the reduced power of the non-
parametric test was used (i.e., expect that a t-test with 85% power to have at least 80% 
power when the van Elteren test is applied). A two-side 5% test will be used to compare 
each active dose to placebo. These calculations give N = 115 infants per group. To 
account for the reduction in power caused by potential missing data, the sample size was 
increased to 130 per group or a total sample size of 390 
 
1.4 GENERAL CONSIDERATIONS 
All descriptive statistics for continuous variables will be reported using mean, standard 
deviation (SD), median, minimum and maximum.  Categorical variables will be 
summarized as number (percent) of subjects. 
 
Confidence intervals (CIs) will be 95% and all tests will be two-sided, unless otherwise 
specified in the description of the analyses. 
 
P-values will be rounded to three decimal places. If a P-value is less than 0.001 it will be 
reported as “<0.001.”  If a P-value is greater than 0.999 it will be reported as “>0.999.” 
 
For both fraternal and identical twins eligible for the study, the primary analysis will 
include only the first-twin (and only twin) to be randomized.  If only one twin is eligible, 
then that twin (whether first to be randomized or second) will be included in the primary 
analysis. The same approach will be applied to the key secondary endpoint, the other 
secondary endpoints, the exploratory secondary endpoints, the other endpoints, and the 
analyses of the primary and key secondary endpoints on per protocol set, unless specifically 
specified which twin(s) will be included.

1.5 
DEFINITIONS OF ANALYSIS SET 
1.5.1 Full Analysis Set (Intention-to-treat)  
The FAS will consist of all randomized singletons and, for twins who both participate in 
the study, both will be included.  
In the situation where both twins are included in FAS, whether only the first twin to be 
randomized, or the second twin assigned to the same treatment group as the first 
randomized twin, or the both twins who will be included in the efficacy analyses on FAS 
will be explicitly stated in Section 2.2. 
 
1.5.2 
Per-Protocol Analysis Set 
Per- protocol (PP) set consists of subjects in FAS who do not have an important protocol 
deviation. The categories of the importance protocol deviation that are thought to have a 
major impact on the interpretability of the overall interpretation of safety and efficacy of 
the trial are provided in Section 2.1.2. 
The approach described in the protocol of using methods that separate the reasons for 
noncompliance from the effect of study drug (e.g. Robins, 1989) will not be followed. 
Instead, the more common approach of defining a PP set based on study compliance will 
be adopted. This is not considered as a major change although it will be mentioned in 
Section 4.0 – Summary of Major Changes in the Planned Analyses. 
1.5.3 Safety Analysis Set 
The safety analysis set will consist of all infants in whom any study drug (placebo or 
NTRA-2112) was initiated. If both members of a pair of twins are participating in the 
study, the safety analysis set will include both infants. 
1.6 
DEFINITIONS AND CONVENTIONS FOR DATA HANDLING 
1.6.1 Baseline Definition 
Baseline: for evaluations collected at multiple time points prior to initiation of study drug, 
the last assessment before the randomization day (Day 1), will be considered the 
“baseline” evaluation for analysis. 
 
1.6.2 Study Day 
Study Day will be calculated relative to the day of first dose (defined as Day 1), and will 
be used to show start/stop day of assessments and events.

Page 17 of 40 
 
If the assessment (or event) date falls on or after the date of first dose then 
Study Day = Assessment Date – Date of First Dose + 1 
 
If assessment date falls before the date of first dose then 
Study Day = Assessment Date – Date of First Dose 
 
In the case of adverse events or concomitant medications where the assessment date is 
partially or completely missing, Study Day and any corresponding durations will follow 
the conventions given in Appendix 6.1. 
 
1.6.3 End of Study 
The definition of end of study is the final study visit (24 months corrected age follow-up 
visit). 
 
1.6.4 Analysis Visit Windows for Follow-up Visits 
For follow-up endpoints at 3, 12 and 24 months, the variables will be summarized based 
on the closest scheduled visit for that variable based on “analysis-defined visit windows.”  
These visit windows have been constructed so that every observation collected can be 
allocated to a unique visit. No visit windows will be defined for the screening visit. 
 
The analysis-defined visit windows for assessments conducted at 3-month, 12-month, and 
24-month are summarized in Table 2. 
 
Table 2: Analysis - Defined Visit windows for measurements recorded for follow-up visits

24 -month 
24-month corrected age 
18-month + 1 day until 30-
month corrected age 
Note: 7.5-month is the mid-point between 3-month and 12-month, and 18-month is the mid-point between 12-month and 
24-month. The exact mid-point will be determined as the day which has equal distance from two adjacent visits if there 
are odd number of days in between, or it is the earlier visit pluses a half number of days if there are event number of days 
in between, 
If multiple readings are recorded within a single analysis-defined visit window, the 
following rules will apply: 
• If there are 2 or more valid, non-missing observations within the same visit window, 
then the non-missing one closest to the scheduled visit day will be used in the 
analysis. 
• If 2 valid observations are equidistant from the scheduled visit, then the non-missing 
observation with the earlier collection date will be used in the analysis.

Page 18 of 40 
 
• If 2 or more valid observations are collected on the same day, then the non-missing 
observation with the earlier collection time will be included in the analysis. 
If a visit window does not contain any observations, then the data will remain missing. 
1.6.5 Missing Data Handling Rules 
The primary approach to handling missing ranks for the primary and the key secondary 
endpoints will be multiple imputation.  The details are provided in Section 2.2.1.3.  
No imputation will be made for other secondary or exploratory endpoints. No imputation 
will be made for any safety or lab measurements. 
 
1.7 MULTIPLE COMPARISONS/MULTIPLICITY 
This trial has one primary and one key secondary endpoint. The study is comparing each 
of two doses to placebo; a hierarchically ordered testing procedure will be used to test the 
primary endpoint, then secondary endpoint for the high dose first, then for the lower dose. 
Nutrinia believe that insulin as a growth factor will have effect with both doses.  We expect 
that there is an opportunity for exploring higher dose that may yield a more favorable 
clinical effect than the lower dose that was used in the phase 2.  Thus for that reason, a 
hierarchal approach is now being considered in the analysis. This procedure will preserve 
the type 1 error rate of 5% overall. The detailed testing procedure and the stopping rules 
are described below. 
 
1. The NTRA – 2112 2000 µIU Insulin/ml group is compared with the placebo group 
for the primary endpoint using a two-sided test at the 0.05 significance level. 
• If the null hypothesis is not rejected, no further comparisons are made. 
• If the null hypothesis is rejected, comparisons continue in the next step. 
2. The NTRA – 2112 2000 µIU Insulin/ml group is compared with the placebo group 
for the key secondary endpoint using a two-sided test at the 0.05 significance level. 
• If the null hypothesis is not rejected, no further comparisons are made. 
• If the null hypothesis is rejected, comparisons continue in the next step. 
3. The NTRA – 2112 400 µIU Insulin/ml group is compared with the placebo group 
for the primary endpoint using a two-sided test at the 0.05 significance level. 
• If the null hypothesis is not rejected, the final comparison will not be made. 
• If the null hypothesis is rejected, the final comparison in the next step will 
be made. 
4. The NTRA – 2112 400 µIU Insulin/ml group is compared with the placebo group 
for the key secondary endpoint using a two-sided test at the 0.05 significance level.

1.8 EXAMINATION OF SUBGROUPS 
Descriptive statistics of effect sizes of treatment on the primary and key secondary 
endpoints will described in the following subgroups: 
 
• Gestation age group 
• Region (North America, Europe, and Israel) 
• Birth weight (< 750g, ≥750g and < 1000g, ≥1000g and < 1500 g, ≥1500g) 
• Gender 
• Ethnicity 
• Enteral feedings type: 
o Only own mother’s milk 
o Only donor breast milk  
o Only human milk (combined)  
o Only Infant formula 
o Only own mother’s milk and formula, in any combination of proportions 
o Only donor breast milk and formula, in any combination of proportions 
o Only human milk and infant formula, in any combination of proportions 
 
For an infant to be in one of the above 7 categories, for example “Only own mother’s 
milk”, the infant had to be on own mother’s milk for enteral feeding every day during the 
treatment period up to Day 28.  
1.9 POOLING OF CENTERS 
The study centers are not planned to be used as a stratification factor nor a covariate in 
the statistical modeling and testing, therefore it is not necessary to pool small centers 
together. 
 
2 STATISTICAL ANALYSES 
Although the study includes follow-up visits up to 24 months corrected age, the primary 
analysis will be completed after the last subject has completed the 3 month corrected age 
follow-up visit.  At that time, all data up to and including the 3 month follow-up visit will 
be cleaned and the study unblinded.   
Subject Information 
2.1.1 Disposition of Subjects 
Subject disposition will be summarized based on all subjects who were screened for the 
study. The total number of subjects screened and the number (percent) of subjects who 
failed screening will be summarized, based on data reported on the eligibility assessment 
in the eCRF.

The distribution of the number of subjects enrolled by each country/region and site will 
be summarized for each treatment group and overall. 
Study Completion: The number (percent) of randomized (including twins) and treated 
subjects who completed the treatment period, and 3-month follow-up visits as planned, 
and those who discontinued from the study (with reasons) will be summarized according 
to the end of treatment assessment in the eCRF.  
A subject data listing of disposition of subjects and the reasons for screen failures will be 
provided. 
2.1.2 Protocol Deviations 
Important deviations will be those which are considered to potentially impact upon the 
interpretation of the primary endpoint in the study.  Only important protocol deviations 
will be listed and tabulated in the CSR. 
The following categories of protocol deviations will be reviewed by medical advisors and 
statisticians prior to unblinding to determine those which are considered important 
deviations. 
• Subjects who do not meet the inclusion criteria 
• Subjects who meet any of the exclusion criteria 
• Concomitant use of disallowed medications (to be identified through programming) 
• Subjects who developed withdrawal criteria during the study but were not withdrawn 
 
Subjects for whom an important protocol deviation was recorded that impacts the 
interpretation of the overall study efficacy and/or safety outcomes will have a footnote 
added to applicable output to describe the deviation and its potential impact.  Such 
subjects will be identified as part of the protocol deviation review process, prior to 
unblinding. 
The number and percentage of subjects with important protocol deviations in the FAS 
will be presented by treatment group. 
 
A listing of these cases will be provided for all important protocol deviations. 
 
2.1.3 Demographics and Baseline Characteristics 
Demographic data will be summarized for each treatment group using descriptive 
statistics on FAS. The following continuous and categorical demographic variables will 
be summarized and tabulated for each treatment group.

2.2.1.2 Key Secondary Analysis 
The key secondary endpoint is the number of days to achieve discharge from hospital or 
readiness for discharge (NRD), whichever occurs first. 
The FAS will be used to test the key secondary efficacy endpoint.  See Section 1.4 for 
explanation of how twins will be handled in this analysis. 
For the key secondary endpoint, the following hypothesis will be tested: 
H0: 
The distribution of the number of days to NRD is the same in the treated 
and the placebo groups. 
 
H1: 
The distribution of the number of days to NRD differs in the treated and 
the placebo groups. 
 
where NRD = number of days to discharge (or readiness for discharge) from the hospital.  
To maintain the overall study-wide two-sided Type I error rate at 0.05, a hierarchically 
ordered testing procedure, described in section 1.7, will be used. The testing of the key 
secondary endpoint will be  by the van Elteren test, stratified by gestational age group 
and region (North America, Europe, and Israel) with a threshold for statistical 
significance of P<0.05.  The average rank will be used for tied NRD values. 
The Hodges–Lehmann estimator will be used to estimate the treatment differences 
(NTRA-2112 dose minus placebo) in days and their 95% confidence intervals.

2.2.1.3.2 Ranks for NEC and Death of Subjects 
 
Infants who experience NEC (Necrotizing Enterocolitis) will be assigned ranks of NFE 
according to censoring times of 29 days and infants who die will be assigned ranks of 
NFE according to censoring times of 30 days. The individual ranks among subjects 
experiencing NEC and the individual ranks among subjects who die will be handled 
according to Section 1.3.3. 
 
Since it can take significantly longer than 28 days to be discharged or being ready to be 
discharged, infants who experience NEC (Necrotizing Enterocolitis) will be assigned 
ranks of NRD according to censoring times of 181 days and infants who die will be 
assigned ranks of NRD according to censoring times of 182 days. The individual ranks 
among subjects experiencing NEC and the individual ranks among subjects who die will 
be handled according to Section 1.3.3. 
 
 
 
2.2.1.4 Sensitivity Analysis: Missing Values 
 
Some infants in the FAS are expected to drop out of the study or, for some other reason, 
not to have a ranking. As described in Section 2.2.1.3, multiple imputation will be used to 
include these infants in the analysis of the primary and key secondary endpoint. 
 
The following sensitivity analyses will be conducted on the primary and key secondary 
endpoint to explore the effect of these missing values:  
 
• Worst reasonable case analysis: Infants in an NTRA-2112 group with a missing 
rank will be assigned the median rank in the placebo group and infants in the placebo 
group with a missing rank will be assigned the median rank in the combined NTRA-
2112 groups. The van Elteren test, stratified by gestation age group and region (North 
America, Europe, and Israel) will be performed. 
 
• Best reasonable case analysis: Infants in an NTRA-2112 group with a missing rank 
will be assigned the median rank in the respective NTRA-2112 group and infants in 
the placebo group with a missing rank will be assigned the median rank in the

placebo group. The van Elteren test, stratified by gestation age group and region 
(North America, Europe, and Israel) will be performed. 
 
Tipping point analysis: Infants in either of the NTRA-2112 groups with a missing 
rank will be assigned varying ranks to find the point at which statistical significance 
is lost.  Specifically, if the outcome of the hypothesis test is in favor of a NTRA-2112 
group over the placebo group (P-value <0.05), then one day will be added to each of 
the imputed values for the NTRA-2112 group in each copy of the imputed dataset, 
whilst the data for the placebo group will remain the same.  The 5 imputed datasets 
will then be combined to run the van Elteren test results using PROC MI procedure in 
SAS. This “day shifting” will be repeated with one extra day at a time until the 
outcome of the hypothesis test is no longer in favor of the NTRA-2112 group over the 
placebo group (i.e. the P-value becomes greater than 0.05). As the overall ranks of 
NTRA-2112 group increase as the results of adding one day each time to each 
imputed missing rank, the highest rank for the imputed missing ranks will be 
truncated at Day 30 (implying that a missing data point is as bad as a death). 
 
• Survival (“time-to-event”) analysis: a stratified log rank test will be performed to 
compare time-to-FEF (the first day of Full External Feeding). In this analysis, infants 
who experience NEC will be assigned censoring times of 29 days and infants who die 
will be assigned censoring times of 30 days. Any other infants who withdraw from 
the study early will be considered censored at the day of their last participation in the 
study (unless they have already achieved FEF in which case they will not be 
censored). 
 
      This time to event analysis will be reported for the time to FEF as the first of 3    
      consecutive days and again as the third of 3 consecutive days of enteral feeding. 
 
2.2.1.5 Sensitivity Analysis: The Second (Born) Twin 
The second twin is the one who is assigned to the same treatment group as the first (born) 
randomized twin.  
 
The following analyses will be performed on FAS to include the second twin.  
 
One analysis will repeat test the primary and key secondary endpoints replacing the first-
randomized twin by the second twin.  
 
Another analysis will be a hierarchical mixed model that includes both twins in a way 
that accounts for the possible correlation between them. For the mixed effects model, the 
dependent variable will be the number of days, the independent variable is the treatment 
group, with gestation age group and the region (North America, Europe, and Israel) as 
two class covariates. A twin effect will be included in the model as a random cluster 
effect. For each singleton, the cluster has one subject, and for each twin the cluster will 
have two subjects. This random cluster effect is used to model the correlation within each 
twin-pair under the compound symmetry covariance structure.

For infants who experience NEC (Necrotizing Enterocolitis) or death, their ranks will be 
assigned in the same way as described in Section 2.2.1.3.2. 
 
2.2.1.6 Sensitivity Analysis: The Per Protocol Set 
Per protocol set consists of subjects in FAS who do not have any important protocol 
deviations. The important protocol deviations will be determined before the database is 
unblinded. The analysis of the primary and the key secondary endpoint will be repeated 
on the per protocol set. 
 
2.2.1.7 Sensitivity Analysis: Breaking Tied NFE Rankings 
For the infants who have the same NFE value which lead to the tied NFE rankings, their 
baseline enteral feeding volume will be used to break the tie. Specifically, the infant with 
the lowest baseline enteral feeding volume will be ranked lowest among them, the infant 
with the second lowest enteral feeding volume will be ranked the second lowest, and so 
on. For infants who have the same NFE rank and the same baseline enteral feeding 
volume, their NFE ranks will remain to be tied.  For subjects who have unique NFE 
rankings, they will retain their ranks if there were no ties. For infants who experience 
NEC (Necrotizing Enterocolitis) and infants who die, their NFE will be assigned to Day 
29 and Day 30 without breaking ties by their baseline enteral feeding volume. The 
individual ranks among subjects experiencing NEC and the individual ranks among 
subjects who die will be handled according to Section 1.3.3. For subjects who didn’t meet 
the enteral feeding criterion during the treatment period, their NFE will be censored on 
Day 28 without breaking by their baseline enteral feeding volume. The testing of such 
NFE ranking will be analyzed in the same way as described in 2.2.1.1 for the van Elteren 
test, stratified by gestational age group and region (North America, Europe, and Israel).  
 
2.2.1.8 Supportive Analysis: Infants Who Achieved Partial Enteral Feeding  
The number and percent of infants who achieve enteral feeding of at least 150 ml/kg/day 
for at least 3 consecutive days, only two consecutive days, and just one day will be 
summarized for each treatment group.  
  
2.2.2 Other Secondary Endpoints 
The following other secondary endpoints will be analyzed on FAS only.  
• Growth velocity (g/kg/day) at 6, 8, and 10 days, the last day of treatment (or Day 28), 
day of discharge, 3-month follow-up, 12-month follow-up, and 24-month follow up 
• Change in Z-score at 6, 8 and 10 days, the last day of treatment (or Day 28), day of

days from initiation of treatment. 
• Total number of days receiving parenteral nutrition 
• Number of days to 120Kcal/kg/day 
• Number of days to wean-off PN 
 
For the continuous variables (growth velocity, z-score, body weight), ANCOVA analysis 
will be performed at each time point of interest, including treatment, the stratification 
factors of gestation age and region (North America, Europe, and Israel) as class variables, 
and the baseline values as a continuous covariate, the estimated treatment differences 
(NTRA-2112 minus placebo), 95% confidence intervals, and P-values will be provided. 
For the variable of number of day to a given event, the van Elteren test stratified for 
gestation age and region will be performed. The average score will be used for the ties. 
Infants who experience NEC (Necrotizing Enterocolitis) and infants who die will be 
assigned the second worst and the worst ranks. The individual ranks among subjects 
experiencing NEC and the individual ranks among subjects who die will be handled 
according to Section 1.3.3. 
 
For percent of infants reaching full external feeding, Cochran-Mantel-Haenszel (CMH) 
test stratified for gestation age and region will be performed. 
Statistical testing of these other secondary endpoints will be considered exploratory and 
will not control for Type I error rate inflation. 
No imputation will be performed for the missing values for the other secondary 
endpoints. 
2.2.3 Exploratory Secondary Efficacy Endpoints 
The FAS will be used to analyze the exploratory secondary efficacy endpoints. The 
continuous variables will be analyzed using ANCOVA analysis at each time point of 
interest, including treatment, the stratification factors of gestation age group and region 
(North America, Europe, and Israel) as class variables, and the baseline values as a 
continuous covariate, the estimated treatment differences (NTRA-2112 minus placebo), 
95% confidence intervals, and P-values will be provided. 
For percent enteral feeding from total nutrition and percent parenteral nutrition from total 
nutrition, CMH test stratified for gestation age group and region (North America, Europe, 
and Israel) will be performed.

SAFETY ANALYSIS 
All safety analyses will be performed on the Safety Analysis Set.  Safety data presented 
by treatment group will be summarized on an “as treated” basis.  Safety variables include 
the extent of exposure, treatment-emergent adverse events (TEAEs), clinical laboratory 
parameters, vital signs, and other relevant variables.  Study Day 1 for all safety analyses 
is defined as the date of the first dose of study drug. 
Both fraternal and identical twins enrolled in the study, will be included in the safety 
analyses. 
 
2.3.1 Treatment Compliance

duration (days).   The following describes the calculation algorithm for individual subject 
compliance based on the information on eCRF. 
1. If no study drug was missed for the day, then the daily compliance is 100%. 
2. If the study drug was missed for the day, then based on how many feeds were 
missed and how many feeds were planned for the day, the daily compliance will 
be calculated as the ratio of number of feeds with study drug administered over 
the number of feeds planned x 100%. 
For each subject, the daily treatment compliance will be calculated for each day while the 
subject was supposed to receive the treatment.  
For an infant, the average of the daily compliance over the treatment period (up to Day 
28) will be the overall treatment compliance for this infant.  
The overall treatment compliance values will be summarized using descriptive statistics 
for each treatment group. 
A subject data listing of treatment compliance will be provided. 
2.3.2 Safety Outcome Variables 
The following safety data will be collected: reported AEs (including SAEs), clinical 
chemistry, physical examination, vital signs, respiration status, complete blood count, 
glucose level, anti-insulin antibodies, and stool frequency and consistency.  
All safety measurements will use all available data for analyses, including data from 
unscheduled visits and repeated measurements. 
Change from baseline to each post-treatment time point where scheduled assessments 
were made will be calculated for relevant measurements.  
No safety data will be imputed. The handling of partial/missing dates for AEs and 
prior/concomitant medications is detailed in Appendix 6.1. 
2.3.2.1 Adverse Events 
Adverse events (AEs) experienced by the subjects will be collected from initiation of 
dosing through the final study visit and will be coded using the latest version of the 
Medical Dictionary for Regulatory Activities (MedDRA) per the Data Management Plan.  
Adverse event data will be categorized according to their onset date into the following 
study periods: 
• Treatment-emergent adverse events are the ones that they started during or after 
administration of the first dose of study medication up till the last dose date + 30 
days. In addition, medical history events that worsen in severity after the start of 
dosing will be considered treatment-emergent adverse events.

• AEs during the 3 month corrected age follow up period : < last dose date + 30 days - 
<= Month 3 follow-up visit 
• AEs during the 12 month corrected age follow up period : < Month 3 follow-up visit - 
<= Month 12 follow-up visit 
• AEs during the 24 month corrected age follow up period : < Month 12 follow-up visit 
- <= Month 24 follow-up visit  
 
If an AE has a missing onset date then unless the stop date of the AE indicates otherwise, 
this will be considered an ongoing AE. Similarly, if an AE has a partial onset date, then 
unless the partial onset date or the stop date indicates otherwise, this will be considered 
an ongoing AE. 
Only those AEs that are treatment-emergent will be included in summary tables.  All AEs, 
treatment-emergent or otherwise, will be presented in subject data listings. 
TEAEs will be summarized by treatment group, separately for the four reporting periods 
above.  The incidence of TEAEs will be reported as the number (percent) of subjects with 
TEAEs within SOC and PT.  Subjects will be counted only once within a SOC and PT, 
even if the subject experienced more than one TEAE within a specific SOC and PT. The 
number (percent) of subjects with TEAEs will also be summarized by maximum severity 
of Common Terminology Criteria for Adverse Events (CTCAE) and the relationship to 
the study drug (unlikely, possible, probable). 
2.3.2.2 Deaths, Serious and Other Significant Adverse Events 
The number (percent) of subjects with TEAEs leading to death will be summarized by 
MedDRA SOC and PT for each treatment group separately for the on-study period and 
the long-term follow-up period.  A subject data listing of all AEs leading to death will be 
provided.   
The number (percent) of subjects with treatment-emergent serious adverse events (SAEs) 
will be summarized by MedDRA SOC and PT for each treatment group, separately for 
the on-study period and the long-term follow-up period.  A subject data listing of all 
SAEs will be provided. 
The number (percent) of subjects with TEAEs leading to discontinuation from study 
treatment will be summarized by MedDRA SOC and PT for each treatment group during 
the on-study period.  A subject data listing of all AEs leading to discontinuation from 
study treatment will be provided.

2.3.3.1 Blood Chemistry 
For the purposes of clinical chemistry shift tables, baseline will be defined as the 
assessment prior to randomization and maximum or minimum value post-baseline will be 
calculated over the entire study period, up to the 3-month follow-up visit. 
Changes in blood chemistry variables between baseline and post-baseline assessments 
will be calculated.  The change from baseline is defined as the post-baseline visit value 
minus the baseline visit value.  There will be no imputation for missing values.  For 
values recorded with a leading greater than or less than symbol (“>”, “<”), the reported 
numeric value will be used for analysis and the value with the symbol will be included in 
the listings, unless otherwise specified.  For example, a value of <0.01 will be analyzed 
as 0.01 and listed as <0.01. 
Absolute values will be compared to the reference range and classified as normal, 
abnormal, or not performed.  The abnormal values will be further classified as clinically 
significant or not clinically significant. 
Data for subjects who have treatment-emergent changes outside laboratory reference 
ranges will be presented.  This data presentation will include all visits for this subset of 
subjects. 
Maximum post-baseline ALT and AST will be presented, expressed as multiples of ULN.  
AST and ALT will be presented in multiples of the following ULN ≤1, >1-3, >3-5, >5-
10, >10. 
2.3.3.2 Blood Glucose Level 
Blood glucose level will be monitored twice/day for the first 4 days (96 hours), with one 
measurement approximately 1 hour after the study drug administration each day, and then 
starting at Day 4 every other day (at 07:00-10:00, before a meal). 
The blood glucose level will be summarized using descriptive statistics for each treatment 
group by time and the day during the treatment period (Day 1 to Day 28), and the 3-
month follow-up visit. 
A shift table will be provided to summarize the changes from the baseline statuses to the 
post-baseline statuses.  
Graphical presentation of the mean glucose level over time by treatment group will be 
provided. 
A subject data listing of blood glucose level will be provided. 
2.3.3.3 Respiration Status 
Fraction of inspired oxygen will be summarized using descriptive statistics. The other 
categorical variables will be summarized as percentages for each treatment group.

respiration rate, temperature, weight) and changes from baseline will be presented by 
visit and treatment group. 
Baseline to maximum post-baseline and baseline to minimum post-baseline value shift 
tables will be generated, as applicable for each parameter and will include subjects with 
both baseline and post-baseline data. 
A subject data listing of vital signs will be provided. 
2.3.4.2 Physical Examinations 
Physical examination results are collected at screening, each treatment day, the day of 
discharge, and 3-month corrected age follow-up visits. Each component of the physical 
examination will be recorded as normal, abnormal not clinically significant, or abnormal 
clinically significant. 
Physical examination results will be summarized by treatment group in frequency and 
percentage at these visits. 
A subject data listing of physical examination will be provided. 
2.3.5 Other Safety Analyses

FUTILITY ANALYSIS AND DATA MONITORING COMMITTEE (DMC)  
3.1 
FUTILITY ANALYSIS 
The study will include an interim futility analysis of the primary endpoint. The interim 
futility analysis will be performed when at least 150 subjects have been randomized. The 
date for data transfer, which includes the values for the primary endpoint and the key 
secondary endpoint, and gestation age group and region (North America, Europe, and 
Israel) will allow the randomized subjects to be followed for at least 28 days. The 
multiple imputation for the missing values due to drop-out will be implemented as 
described in Section 2.2.1.3.1. if more than 10% of values are missing due to early 
termination other than NEC or death for the primary endpoint. A partial data lock (snap 
shot) will be completed after the data transfer and the data and SAS program will be 
transferred to the unblinded statistician to complete the interim futility analysis. 
To maintain adequate statistical power for the final analysis of the primary endpoint, a 
blinded sample size re-estimation will be carried out at the time of the interim futility 
analysis. The blinded team statistician will calculate the pooled standard deviation of the 
primary endpoint without distinguishing treatment groups. The sample size may be 
increased up to 450 patients (total) if the estimated standard deviation is at least 10% 
larger than that assumed in the sample size section of the protocol. In order to keep the 
sample size re-estimation independent of the futility analysis, the sample size re-
estimation will be based on the blinded data used for the futility analysis to obtain the 
pooled standard deviation.  The result of the blinded review will be documented and 
reported to the sponsor and DMC before the DMC meets to consider futility.  The final 
sponsor decision on sample size will be provided to the DMC and will be the primary 
driver in the futility assessment. Because the analysis will be based on ranks, a van 
Elteren test will be used to compare NTRA-2112 to placebo. To calculate sample size, a 
2-sample t-test for 85% power to account for the reduced power of the non-parametric 
test was used (i.e., expect that a t-test with 85% power to have at least 80% power when 
the van Elteren test is applied). With 144 evaluable patients per arm, assuming a standard 
deviation of 5.0 days, a 2-sample t-test will have 85% power to detect a mean difference 
of 1.77 days in the number of days to reach full enteral feeding between the treated and 
placebo arm. Similarly, assuming a standard deviation of 4.0 days, a 2-sample t-test will 
have 85% power to detect a mean difference of 1.42 days.  Considering a dropout rate of 
5%, an enrollment of 152 patients per arm will likely recruit 144 per arm evaluable

patients. 
For the futility analysis, the conditional power of showing statistically significant (P≤0.05) 
evidence of benefit on the primary endpoint at the final analysis will be calculated for each 
dose group. Conditional power will be calculated from the z-value based on the interim 
analysis, treating the primary endpoint as a continuous variable, approximately following 
the normal distribution. The conditional power will be calculated based on the observed 
interim trend of effect size, not the original expectation in the sample size calculation. If 
the conditional power is less than 35% in either dose, continuing to enter infants in that 
dose group will be considered statistically futile.  
The futility analysis results, including the calculated conditional power for each dose group 
and summaries of selected key safety parameters (adverse events, lab tests, physical exams, 
and vital signs), will be presented to the Data Monitoring Committee, who will review the 
results and make a final recommendation regarding the continuation or discontinuation of 
one or both dose arms. The recommendation will be based on the conditional power and 
the totality of the clinical data available. 
3.2 
 DATA MONITORING COMMITTEE  
An independent DMC is established and responsible for monitoring the trial to ensure the 
safety of patients in the trial. The DMC will review safety data and will make 
recommendations whether to continue or terminate the study. The DMC analyses and 
operations will be formally separated from the sponsor, the investigators, and the Steering 
Committee. 
 
The DMC’s responsibilities are to: 
• Review safety and efficacy data during the study with consideration for the impact on 
patient safety, as well as the ethics of continued study conduct. 
• Conduct review results of interim and final safety evaluations of the study, including 
an interim analysis for futility. 
• Consider factors external to the study when relevant information becomes available, 
such as scientific or therapeutic developments that may have an impact on safety, 
scientific integrity, or the ethics of conducting the study. 
• Review and evaluate ad hoc safety issues concerning the study that arise from any 
Serious Adverse Drug Reaction (an adverse event that might be related to the study 
drug, i.e. a causal relationship between exposure to the study drug and the serious 
adverse event is at least possible) or other safety matters at the request of the sponsor. 
• Make recommendations to the sponsor concerning continuation/termination, or other 
modifications of the study based on the observed beneficial or adverse effects of the 
study drug. 
• Operate according to the procedures described in the DMC charter. 
 
A DMC Charter has been developed that defines the DMC organization, responsibilities, 
relationship with other trial entities, and the purpose and schedule of the DMC meetings.

The charter provides the procedures for ensuring confidentiality, proper communication, 
scopes of the interim data to be presented, and the statistical guidelines for interim futility 
analysis by the DMC.

SUMMARY OF MAJOR CHANGES IN THE PLANNED ANALYSES 
The PP set is defined differently from the protocol, but the difference is not considered to 
be major. The approach described in the protocol of using methods that separate the 
reasons for noncompliance from the effect of study drug (e.g. Robins, 1989) will not be 
followed. Instead, the more common approach of defining a PP set based on study 
compliance will be adopted. PP analysis will only be supportive of the primary intention-
to-treat analysis based on the FAS. 
The treatment difference between two NTRA-2112 doses will be estimated for the 
primary endpoint, key secondary endpoint, exploratory secondary endpoint, and other 
endpoints. 
The Bonferroni correction was described in the protocol for testing the primary and the key 
secondary endpoints simultaneously for each dose level. Nutrinia believe that insulin as a 
growth factor will have effect with both doses.  We expect that there is an opportunity for 
exploring higher dose that may yield a more favorable clinical effect than the lower dose 
that was used in the phase 2.  Thus for that reason, a hierarchical approach is now being 
implemented in the analysis. This procedure is described in Section 1.7 of this SAP to allow 
testing the primary endpoint, then secondary endpoint for the high dose first, then for the 
low dose while maintaining the type 1 error rate of 5% overall. 
 
The sample size was re-calculated in Section 1.3.3 due to the change in the testing 
procedure stated above.  
Section 2.2.1.3.2 was modified to allow longer time, up to 180 days, to observe the actual 
time for discharge or being ready to be discharged (NRD).  
Section 2.2.1.7 was added for a sensitivity analysis using the baseline enteral 
feeding volume to break the tied NFE ranking.  
Section 2.2.1.8 was added for a summary of number and percent of infants 
who achieve the complete and partial enteral feeding success for each 
treatment. 
The reporting periods for AE reporting have been further defined in Section 2.3.2.1. 
Section 3.1. The timing of the sample size re-estimation relevant to the futility analysis is 
further clarified. The conditional power is raised from 20% to 35%. Based on the 
conditional power and the totality of the clinical data available at the futility analysis, the 
DMC will recommend to continue or discontinue one or both dose arms. The sponsor 
will consider increasing the total sample size up to 450 patients based on the sample size

6 APPENDIX 
6.1 
PARTIAL DATES FOR ADVERSE EVENTS AND PRIOR/CONCOMITANT MEDICATION  
Dates missing the day or both the day and month of the year will adhere to the following 
conventions to classify treatment-emergent AEs and to classify prior/concomitant 
medications. When the conventions are applied to infants, if an imputed date is before 
infant’s birthday, the date should be set on the birthday. For example, if a missing date of 
AE is set on January 1, but January 1 is before infant’s birth, then the date of AE should 
be set on the birthday. 
Adverse events 
The missing day of onset of an AE will be set to: 
First day of the month that the event occurred, if the onset YYYY-MM is after 
the YYYY-MM of first study treatment 
The day of the first study treatment, if the onset YYYY-MM is the same as 
YYYY-MM of the first study treatment 
The date of informed consent, if the onset YYYY-MM is before the 
YYYY-MM of the first treatment. 
The missing day of resolution of an AE will be set to: 
The last day of the month of the occurrence. If the subject died in the same 
month, then set the imputed date as the death date. 
 
If the onset date of an AE is missing both the day and month, the onset date will be set to: 
January 1 of the year of onset, if the onset year is after the year of the first 
study treatment 
The date of the first treatment, if the onset year is the same as the year of the 
first study treatment 
The date of informed consent, if the onset year is before the year of the first 
treatment 
 
If the resolution date of an AE is missing both the day and month, the date will be set to: 
December 31 of the year of occurrence. If the subject died in the same year, 
then set the imputed date as the death date.

Prior/concomitant medication 
The missing day of start date of a therapy will be set to the first day of the month or the 
infant’s birthday, whichever is later, that the event occurred. 
The missing day of end date of a therapy will be set to the last day of the month of the 
occurrence. 
If the start date of a therapy is missing both the day and month, the onset date will be set 
to January 1 of the year of onset. 
If the end date of a therapy is missing both the day and month, the date will be set to 
December 31 of the year of occurrence. 
If the start date of a therapy is missing and the end date is not a complete date then the 
start date will be set to the date of the first study visit. 
 
If the start date of a therapy is missing and the end date is a complete date 
and the end date is after the date of the first study visit then the start date will 
be set to the date of the first study visit. 
otherwise the start date will be set to the end date of the therapy. 
 
If the end date of a therapy is missing and the start date is not a complete date then the 
end date will be set to the date of the last study visit. 
 
If the end date of a therapy is missing and the start date is a complete date 
and the start date is prior to the date of the last study visit then the end date will 
be set to the date of the last study visit. 
otherwise, the end date will be set to the start date of the therapy.
