Title of Study: 
Efficacy and Safety of Racecadotril in the treatment of Taiwanese children aged 3 to 60 months 
suffering from acute diarrhea: A prospective, open-label, multicenter, single arm study  
 
 
 
  
 
Study Duration: 
approximately 2 years  
(from First Subject First Visit until Last Subject Last Visit) 
End of Study is defined as Last Subject Last Visit. 
Phase of Development: 
III (post approval 
commitment) 
Objectives: 
 
Primary objective: 
The primary objective is to evaluate the efficacy of Racecadotril in addition to standard treatment 
oral rehydration solution (ORS) in infants and children (3 months until 60 months) with acute 
diarrhea measured as duration of diarrhea (hours) between the start of treatment until final 
diarrheal/watery stool or end of study treatment (treatment duration maximal 5 days).  
Duration of diarrhea is defined as date and time of the evacuation of the final watery/diarrheal 
stool derived from the daily diary. 
Secondary objective(s): 
 
• Time until recovery, defined as date and time of the evacuation of the first of two 
consecutive normal stools or no stool within 12 hours after the first normal stool. 
 
• Number of recovered subjects in total and until each individual treatment day. Mean and 
median time until recovery. 
 
• Global Physician Assessment (GPA) at the end of treatment (at the discretion of the 
investigator): 
o 1 = Complete relief of acute diarrhea, 
o 2 = marked improvement of acute diarrhea, 
o 3 = moderate improvement of acute diarrhea,

o 4 = slight improvement of acute diarrhea,  
o 5 = no change in acute diarrhea,  
o 6 = worsening of acute diarrhea.  
(Treatment success = GPA score of 1 or 2). 
 
• For toilet trained children only: number of stools per day as well as number of watery 
stools per day from start of treatment and until end of study treatment. 
 
Safety and tolerability: To evaluate the safety and tolerability of Racecadotril in addition to 
ORS in infants and children with acute diarrhea by adverse events, physical examination and 
vital signs. 
Methodology: 
This is a prospective, open-label, multicenter, single-arm study evaluating the efficacy and safety 
of Racecadotril in infants and children with acute diarrhea.  
 
 
Screening and Enrolment (Day 1, Visit 1) 
Subjects presenting with acute diarrhea will be evaluated for eligibility. They will undergo a 
physical examination including vital signs, a review of their medical history including 
vaccination history and concomitant medication. If the subjects are eligible, demographics, 
number of stools during the last 12 hours will be assessed as baseline values. On Day 1, the 
subject will start with study treatment. The starting dose will either be the noon or evening dose. 
 
Treatment period (until recovery, maximally five days) 
Subjects will be treated with Racecadotril three times daily according to the body weight dose 
requirement on an out-patient basis for maximum 5 days in addition to ORS. ORS will be 
prescribed by the investigator. The parent(s)/caregiver(s)/legal representative(s) will be 
instructed to stop treatment when the patient recovered. Recovery is defined by the evacuation of 
the first of two consecutive normal stools or no stool within 12 hours. In the evening of each day, 
the parent(s)/caregiver(s)/legal representative(s) will fill in their diaries, documenting date and 
time of each individual stool, the stool consistency of each stool, ORS amount and the study drug 
intake. AEs are to be reported on an ongoing basis. Treatment will stop at recovery (last dose

summarized. A frequency table will be presented for markedly abnormal values. 
Sample size 
In total, 40 subjects will be allocated to receive Racecadotril treatment, 20 subjects in each age 
group (< 24 months of age and ≥ 24 months of age). Results of a recently finalized study in 
Russian children showed that all children under Racecadotril treatment recovered within 3 days 
of drug treatment. A sample size of 40 subjects is sufficient to estimate a two-sided 95% 
confidence interval with the precision of 3.1 percentage points for a recovery of at least 99% of 
the subjects after 3 days of Racecadotril treatment. In order to account for drop-outs, maximum 
48 subjects will be recruited. Recruitment will be stopped once 40 subjects have completed 
the study.

ETHICS 
1.1 
Independent Ethics Committee or Institutional Review Board 
The Sponsor (or an authorized representative) or the Investigator (according to national 
provisions) is responsible for obtaining written approval for the clinical study protocol (including 
all substantial protocol amendments), the written subject informed consent form (including 
written assent, when applicable), informed consent updates, subject recruitment procedures (e.g., 
advertisements) and any other written information to be provided to subjects from an 
Independent Ethics Committee (IEC) / Institutional Review Board (IRB) that complies with the 
local regulatory requirements. 
Written approval of the study must be obtained from the IEC/IRB prior to the study being 
implemented (i.e., shipment of clinical supplies to the Investigator or screening of subjects). 
Copies of the approval documentation will be maintained by both the Investigator and the 
Sponsor (or an authorized representative) in the designated study documentation files. 
The Sponsor (or an authorized representative) or the Investigator (according to national 
provisions) will submit written reports of the clinical study status to the IEC/IRB annually, or 
more frequently if requested by the IEC/IRB. A final study notification should be forwarded to 
the IEC/IRB within 90 days after the study has completed, or in the event of premature 
termination of the study, within 15 days with the rationale for study termination clearly 
explained. Copies of all clinical study status reports (including termination) will be maintained 
by both the Investigator and the Sponsor (or an authorized representative) in the study 
documentation files. 
In accordance with national provisions and the rules of the EU Clinical Trial Directive, the 
Sponsor (or an authorized representative) will inform all participating IECs/IRBs and national 
authorities of all SAEs/SADRs/SUSARs or other safety-related information, which occur during 
the clinical study. 
1.2 
Ethical Conduct of the Study 
Good Clinical Practice (GCP) is an international ethical and scientific quality standard for 
designing, conducting, recording, and reporting studies that involve the participation of human 
subjects. The study will be conducted in compliance with GCP and the applicable national 
regulations to assure that the rights, safety, and wellbeing of the participating study subjects are 
protected consistent with the ethical principles that have their origin in the Declaration of 
Helsinki.

study. The informed consent process will take place under conditions where the parent/legal 
representative has adequate time to consider the risks and benefits associated with the child’s 
participation in the study. Subjects will not be screened or treated until the parent/legal 
representative has signed an approved informed consent written in a language that is 
understandable to the subject’s parent/legal representative. 
The IEC/IRB approved informed consent form will be signed and personally dated by the 
parent/legal representative and the person who conducted the informed consent discussion. Each 
parent/legal representative is to receive a copy of the signed and dated written informed consent 
form and any other written subject information. 
The signature of an impartial witness is to be obtained in the event the subject or the subject’s 
legally acceptable representative is unable to read. Additional signatures on the informed consent 
form may be required in accordance with IEC/IRB requirements or those of the Sponsor (or an 
authorized representative). 
The Investigator is responsible for assuring the appropriate content of the informed consent form 
and that informed consent is obtained from each parent/legal representative in accordance with 
the applicable regulations and guidelines. The original signed informed consent is to be retained 
in the study documentation files. 
The Investigator shall maintain a log of all parent(s)/legal representative(s) who sign the 
informed consent form and indicate if the subject received study drug or, if not, the reason why. 
The subject’s medical records should also document that the informed consent form was signed 
and dated prior to any study-related procedures being performed.

INTRODUCTION 
Racecadotril (acetorphan), an enkephalinase inhibitor, represents a promising approach to the 
treatment of diarrhea. Water and electrolyte transport in the intestinal mucosa is regulated by 
local messengers (neuropeptides, amines, and eicosanoids). Most of them act via the mediation 
of cyclic adenosine monophosphate (cAMP), activating or inhibiting its production from 
adenosine triphosphate. An increase in cAMP is induced by endogenous (e.g. VIP, PGE2) or 
exogenous agents (e.g. V. cholerae, E. coli toxins) and leads to net hypersecretion of water and 
electrolytes. Opiate neuropeptides are localized in the intestine myenteric and submucosal 
plexuses, where they modulate motility (mu receptors) and secretion (delta receptors). Activation 
of mu receptors prolongs intestinal transit while activation of delta receptors reduces intestinal 
secretion of water and electrolytes. Enkephalins activate delta receptors and inhibit 
adenylcyclase, thus facilitating a decrease in cAMP levels with a consequent reduction in water 
and electrolyte secretion. This anti-secretory action, however, is brief because enkephalins are 
rapidly degraded by the membrane peptidase enkephalinase (EC 3.4.24.11). Racecadotril is a 
prodrug that is rapidly hydrolysed in man into the active metabolite thiorphan, which is a 
powerful and selective enkephalinase inhibitor. Thus, the anti-secretory action of enkephalins is 
prolonged in the presence of thiorphan. Furthermore, unlike opiates and loperamide, 
Racecadotril does not act on mu receptors and therefore it does not prolong intestinal transit, nor 
does it favour bacterial growth in the small intestine. Racecadotril is devoid of any central or 
peripheral nervous side effect, at the opposite of opiates, such as respiratory depression or 
inhibition of intestinal transit. 
 
Diarrhea is defined as the passage of unusually loose or watery stools, with a frequency of at 
least three times in a 24-hour period. The objective for treatment of acute diarrhea associated 
symptoms is to prevent and treat dehydration at first, to prevent nutritional damage and to reduce 
the duration and severity of diarrhea. Antidiarrheal drugs have been developed to prevent 
dehydration and to resolve diarrhea on top of with oral rehydration solution (ORS). Ideally 
antidiarrheal has a positive safety profile and have limited or no effects on motility and basal 
intestinal secretion.

STUDY OBJECTIVES 
3.1 
Primary Objective(s) 
The primary objective is to evaluate the efficacy of Racecadotril in addition to standard treatment 
oral rehydration solution (ORS) in infants and children (3 months until 60 months) with acute 
diarrhea measured as duration of diarrhea (hours) between the start of treatment until final 
watery/diarrheal stool before recovery or end of study treatment (treatment duration maximal 5 
days).  
 
Duration of diarrhea is defined as date and time of the evacuation of the final watery/diarrheal 
stool before recovery derived from the daily diary. 
 
3.2 
Secondary Objective(s) 
• Time until recovery, defined as date and time of the evacuation of the first of two 
consecutive normal stools or no stool within 12 hours after the first normal stool. 
 
• Number of recovered subjects in total and until each individual treatment day.  
 
• Global Physician Assessment (GPA) at the end of treatment (at the discretion of the 
investigator): 
o 1 = Complete relief of acute diarrhea, 
o 2 = marked improvement of acute diarrhea, 
o 3 = moderate improvement of acute diarrhea,  
o 4 = slight improvement of acute diarrhea,  
o 5 = no change in acute diarrhea,  
o 6 = worsening of acute diarrhea.  
(Treatment success = GPA score of 1 or 2). 
 
• For toilet trained children only: number of stools per day as well as number of watery 
stools per day from start of treatment and until end of study treatment. 
 
3.3 
Safety Objective(s) 
To evaluate the safety and tolerability of Racecadotril together with oral rehydration solution 
(ORS) in infants and children (3 months until 60 months) with acute diarrhea by adverse events, 
physical examination and vital signs.

STUDY DESIGN 
4.1 
Overall Study Design and Plan-Description 
This is a prospective, open-label, multicenter, single-arm study evaluating the efficacy and safety 
of Racecadotril in infants and children with acute diarrhea in out-patients. The number of 
subjects to be screened is 50 in order to achieve 40 subjects treated with standard treatment (oral 
rehydration solution, ORS) plus Racecadotril. 
 
1.5 mg/kg of Racecadotril will be administered, 3 times daily, via the oral route. Study drug 
intake will start either with the noon or evening dose on day 1. 
 
In infants less than 9 kg: one 10 mg sachet 3 times daily. 
In infants from 9 kg to <13 kg: two 10 mg sachets 3 times daily. 
In children from 13 kg to 27 kg: one 30 mg sachet 3 times daily. 
In children of more than 27 kg: two 30 mg sachets 3 times daily. 
 
Standard treatment is oral rehydration solution (ORS) according to the registered local label and 
the instruction of the investigator. At the start of the trial, alignment will be reached on the 
understanding of treatment of standard ORS with the principal investigator with the aim to use 
the same brand of ORS for the subjects throughout the trial. ORS treatment will be documented 
in the CRF. 
 
Screening and Enrolment (Day 1, Visit 1) 
Subjects presenting with acute diarrhea will be evaluated for eligibility. They will undergo a 
physical examination including vital signs, a review of their medical history including 
vaccination history and concomitant medication. If the subjects are eligible, demographics, 
number of stools during the last 12 hours will be assessed as baseline values. On Day 1, the 
subject will start with study treatment. The starting dose will either be the noon, or evening dose 
depending on the timing of Visit 1. 
 
Treatment period (until recovery, maximally 5 days) 
Subjects will be treated with Racecadotril three times daily according to the body weight dose 
requirement on an out-patient basis for maximum 5 days. The subjects will be treated with ORS 
(according to the registered local label and the instruction of the investigator) in addition to 
Racecadotril. ORS will be prescribed by the investigator and will be taken according to the 
product label and the instruction of the investigator. The parent(s)/caregiver(s)/legal 
representative(s) will be instructed to stop study drug treatment when the patient recovered. On 
each day, the parent(s)/caregiver(s)/legal representative(s) will fill in their diaries, documenting 
the date and time of each individual stool, the stool consistency of each stool (diarrheal/watery or 
normal), the amount of ORS, and the study drug intake. After the occurrence of two consecutive 
normal stools or no stool within 12 hours, the parent(s)/caregiver(s)/legal representative(s) can 
stop recording of the diary and return to the study site for the end of treatment visit. The date of 
recovery is the day when the first of two consecutive normal stools were excreted or the day

when no stool within 12 hours after the first normal stool was observed. AEs are to be reported 
on an ongoing basis.  
 
End of treatment (Day 6 or early recovery, Visit 2) 
The last dose of study drug will be the morning dose of day 6, if not recovered earlier (last dose 
will be the morning dose after recovery, ORS can be continued until Visit 2). On the same day, 
or within 24 hours after recovery (in exceptional cases within 48 hours), the 
parent(s)/caregiver(s)/legal representative(s) will visit the site for the end of treatment visit of the 
child. Data on vital signs, AEs, physical examination and concomitant medication will be 
collected. Subjects will return their diaries and unused medication.  
 
Safety follow-up 
A phone call will be performed 5-7 days after the end of the treatment period for the safety 
follow-up.

7.7 
Prior and Concomitant Therapy 
During the study, subjects are not allowed to be treated with the following treatments:   
• Anti-peristaltic drugs, e.g. loperamide 
• Antibiotics  
• Antipyretics (suppositories)  
Oral antipyretics (acetaminophen or ibuprofen) are allowed to be used concomitantly as 
needed when ear temperature is above 38.3 degrees Celsius, but not longer than two 
consecutive days during the study. If the fever increases above 39 degrees Celsius with two 
repeated measurements within one hours, the subject will be withdrawn.  
• Intestinal antiseptics, e.g. 8-hydroxyquinoline 
• Respiratory decongestants, e.g. phenylephrine  
• Antitussive medication, e.g. noscapine  
Any antitussive drugs, if indicated for pediatric patients, may be given for temporary relief of 
symptoms as PRN (administration on as needed basis) except those containing opium 
alkaloids and derivatives (e.g noscapine). 
• Pre- or Probiotics, e.g. fructooligosaccharides, lactobacilli  
Subjects on continuous probiotic treatment at study start (e.g. Lactobacillus, Bifidobacterium, 
yeast) or probiotic-containing supplements/formula of the same product/brand prior to study 
start can be included. The initiation of pre- or probiotic treatment during the study is 
forbidden as well as the adaptation of the brand/product or dose. 
• Absorbents, e. g. diosmectite, charcoal, pectin, psyllium 
• Zinc-containing medication (other than diaper rash ointments). Diaper rash ointments of 
any kind are allowed. 
• Homemade ORS 
ORS will be provided during the study as judged appropriate by the Investigator. Additional 
intake of self-purchase or self-made ORS is not allowed during the study duration 
• ACE Inhibitors 
• Antispasmodics 
Antispasmodics, indicated for pediatric patients, may be given for temporary relief of 
symptoms as PRN (administration on an as needed basis) in exceptional cases. If 
antispasmodics are needed as daily treatment during the study treatment, the subjects should 
be discontinued. 
• Drugs for symptomatic treatment of diarrhea, e.g. pancreatic enzymes, anticholinergic drugs, 
opiates, diphenoxylate 
• Intravenous fluid or electrolyte replacement. 
 
The presence of bloody or purulent stool and fever above 39 degrees Celsius may indicate either 
the presence of invasive bacteria as a reason for diarrhea or the presence of another severe 
disease. In addition, Racecadotril has not been investigated in patients with antibiotic-associated 
diarrhea. Therefore, Racecadotril should not be administered under these conditions.

stool before recovery derived from the daily diary. 
Secondary Efficacy Variables: 
 
• Time until recovery, defined as date and time of the evacuation of the first of two 
consecutive normal stools or no stool within 12 hours after the first normal stool. 
 
• Number of recovered subjects in total and until each individual treatment day.  
• Global Physician Assessment (GPA) at the end of treatment, at the discretion of the 
investigator: 
o 1 = Complete relief of acute diarrhea, 
o 2 = marked improvement of acute diarrhea, 
o 3 = moderate improvement of acute diarrhea,  
o 4 = slight improvement of acute diarrhea,  
o 5 = no change in acute diarrhea,  
o 6 = worsening of acute diarrhea.  
(Treatment success = GPA score of 1 or 2). 
 
• For toilet trained children only: number of stools per day as well as number of watery 
stools per day from start of treatment and until end of study treatment. 
 
8.2 
Safety Measurements 
Adverse Events 
Requirements for collecting, recording and reporting of AEs are described in Section 9. Each 
subject is to be evaluated at the termination visit. Should any AE be identified at this visit, the 
Investigator will continue to follow the subject as described in Section 9.1.2. 
Vital Signs 
Height and weight must be recorded.

Body temperature will be measured in the morning and in the evening with at least 12 hours 
interval. If the value is >39 degrees Celsius, the measurement has to be repeated within one hour 
to confirm the value. 
Systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse rate are to be measured 
in pediatric appropriate setting. 
Physical Examination 
A physical examination should be performed and any relevant findings are to be recorded on the 
Medical History form in the CRF (for findings from the past that occurred prior to allocation to 
treatment), or on the Adverse Event form in the CRF for findings presently occurring.  
 
8.3 
Other Assessments 
Informed Consent 
Voluntary written informed consent must be obtained from one parent/legal representative prior 
to performing any study-related procedures (see Section 1.3). 
Demographic Data 
Demographic data (gender, age, year and month of birth, race) will be collected for all subjects. 
Medical History 
Any clinical event, including diagnosis, condition, or surgery, that occurred prior to allocation to 
treatment, is to be recorded on the Medical History form. In case a clinical event concerns a 
chronic disorder, which means it started in the past and it is still present at the screening visit, it 
should also be recorded on the Medical History Form. Examples of these events are diabetes, 
migraine, and hay fever. 
Concomitant Medication 
All medication taken by the subject during the study (from signing the informed consent form 
through post-study follow-up) is to be recorded on the Concomitant Medication form, except for 
study drug. 
Subject Diary 
The parent(s)/caregiver(s)/legal representative(s) have to document date and time of each 
individual stool of the subject and the stool consistency (watery, normal) of each evacuation 
continuously. The subject individual stool consistency before start of the diarrhea is defined as 
normal (e.g. taking into account the age and diet, e.g. breast feeding, of the individual subject).

ADVERSE EVENTS 
 
 
9.1 
Adverse Events 
Definition of Adverse Event  
Any untoward medical occurrence in a patient or clinical investigation subject administered a 
pharmaceutical product and which does not necessarily have a causal relationship with this 
treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding, for example), symptom (including an AE occurring from drug abuse, an AE 
occurring from drug withdrawal and any failure of expected pharmacological action), or disease 
temporally associated with the use of a pharmaceutical product, whether or not considered 
related to the pharmaceutical product. 
An elective surgery/procedure scheduled to occur during a study will not be considered an 
adverse event if the surgery/procedure is being performed for a pre-existing condition and the 
surgery/procedure has been pre-planned prior to study entry. However, if the pre-existing 
condition deteriorates unexpectedly during the study (e.g., surgery performed earlier than 
planned), then the deterioration of the condition for which the elective surgery/procedure is being 
done will be considered an adverse event. 
9.1.1 
Recording of Adverse Events 
Any AE should be recorded on the Adverse Events form in the CRF and source documents. In 
order to avoid vague, ambiguous or colloquial expressions, the AE should be recorded in 
standard medical terminology rather than the subject’s own words. Whenever possible, the 
Investigator should group together into a single term signs and symptoms which constitute a 
single diagnosis. 
The existence of or change in an AE may be concluded due to the necessity to administer a 
concomitant medication, from a spontaneous report of the subject, from the physical examination 
or from special tests like ECG, EEGs, laboratory assessments or other study specified tests 
(source of AE). 
For each subject that has signed the informed consent and prior to study drug allocation at any 
dose, any change to medical status should be recorded in patient’s medical file in accordance to 
local requirements and the medical history CRF only.  
Any change to medical status, which occurs after study drug allocation at any dose in the 
specified study AE collection period will be handled as an (S)AE.

Page 32 of 48 
For each subject that has signed the informed consent but does not qualify for allocation to 
treatment, i.e. Screen Failure, any change to medical status (from the time of ICF signature until 
determination of non-qualification for the study) should be recorded in patient’s medical file 
according to local requirements. The related medical status change information will not be 
reviewed by Abbott or delegated staff, and will not qualify as a study (S)AE. 
Each AE, of the treatment arm, is to be evaluated for duration, severity, seriousness and causal 
relationship to the investigational drug. The action taken with study drug, the concomitant 
treatment/therapy introduced and the outcome as well as whether the event led to study 
termination will also be recorded.  
The post-study AE collection period is defined as 30 days after the subject’s safety follow-up 
call (collection of (S)AEs should be passive in this period unless otherwise specified). 
Severity 
The severity of the AE should be characterized as “mild, moderate or severe” according to the 
following definitions: 
- 
Mild events are usually transient and do not interfere with the subject’s daily activities. 
- 
Moderate events introduce a low level of inconvenience or concern to the subject and 
may interfere with daily activities. 
- 
Severe events interrupt the subject’s usual daily activity. 
 
Drug-Event Relationship 
The causal relationship between the study drug and the AE should be characterized according to 
the following: 
- 
Unrelated – there is not a reasonable possibility that the study drug caused the AE. 
- 
Unlikely – suggests that only a remote connection exists between the study drug and the 
event. Other conditions, including concurrent illness, progression or expression of the 
disease state or reaction to concomitant medication, appear to explain the AE. 
- 
Possible – suggests that the association of the AE with the study drug is unknown, 
however the event is not reasonably supported by other conditions. 
- 
Probable – suggests that a reasonable temporal sequence of the AE with drug 
administration exists and, in the Investigator’s clinical judgment, it is likely that a causal 
relationship exists between the drug administration and the AE, and other conditions 
(concurrent illness, progression or expression of the disease state, or concomitant 
medication reactions) do not appear to explain the AE. 
- 
Certain – suggests that an AE, including laboratory test abnormality, occurs in a plausible 
time relationship to drug administration, which cannot be explained by concurrent disease 
or other drugs or chemicals. The response to withdrawal of the drug (de-challenge)

should be clinically plausible. The AE must be definitive pharmacologically or 
phenomenologically, using a satisfactory re-challenge procedure if necessary. 
 
 
Outcome 
The outcome of the adverse event should be classified according to the following definitions: 
- 
Recovered / resolved: the event has resolved (no further symptoms are present and no 
treatment is being received by the subject). 
- 
Recovered / resolved with sequelae: the event has resolved but there may be lingering 
effects present (e.g., a scar following a cut or abrasion). 
- 
Fatal: the subject died as a result of the event. This code should only be used for the event 
that caused the death, not any event that was present at the time of the subject’s death. 
Fatal events require immediately reporting to the Sponsor (or an authorized 
representative). 
- 
Unknown: may only be used in the event that the subject is lost to follow-up and no 
reliable data can be obtained. 
 
All efforts should be made to classify the AE according to the above categories. 
Note: when the AE is ongoing, the outcome will remain blank on the Adverse Events form in the 
CRF. 
9.1.2 
Follow-up of Adverse Events 
All AEs occurring during the study are to be followed up in accordance with good medical 
practice until resolved or judged no longer clinically significant, or if a chronic condition, until 
fully characterized. All follow-up results are to be reported to the Sponsor (or an authorized 
representative). 
9.2 
Serious Adverse Events (SAEs) 
Definitions of Serious Adverse Event (SAE) 
Any untoward medical occurrence that at any dose: 
- 
results in death, 
- 
is life-threatening (an event in which the subject was at risk of death at the time of the 
event; it does not refer to an event which hypothetically might have caused death if it 
were more severe), 
- 
requires inpatient hospitalization or prolongation of an existing hospitalization, 
- 
results in persistent or significant disability/incapacity, 
- 
is a congenital anomaly/birth defect,

is considered an important medical event (an event that may not be immediately life-
threatening or result in death or hospitalization, but based on medical judgment may 
jeopardize the subject and may require medical or surgical intervention to prevent any of 
the outcomes listed above (i.e., death of subject, life-threatening, hospitalization, 
prolongation of hospitalization, congenital anomaly, or persistent or significant 
disability/incapacity). Examples of such events include allergic bronchospasm requiring 
intensive treatment in an emergency room or at home, blood dyscrasia, or convulsions 
that do not result in inpatient hospitalization or the development of drug dependency or 
drug abuse as well as spontaneous or elective abortions, stillbirths and ectopic

STATISTICAL METHODS AND DETERMINATION OF SAMPLE SIZE 
Data handling will be the responsibility of the CRO. The data will be inspected for 
inconsistencies by performing validation checks. Any inconsistencies found will be resolved by 
the monitor after contacting the Investigator. When the data in the database are considered clean 
and the subjects allocated to subject samples in a blind data review, the database will be locked 
to prevent unauthorized access. Next, the database will be made available as SAS® files for 
statistical analysis. 
All details regarding the statistical analysis and the preparation of tables, listings and figures will 
be described in the Statistical Analysis Plan prepared by the CRO and approved by Abbott 
before database lock. 
The statistical analysis will be performed by the CRO. 
10.1 
General Definitions and Conventions 
Time-Related Definitions 
All assessment dates will be related to the first day of study drug administration. This first day of 
drug administration is referred to as Day 1. Day –1 is the day that is preceding Day 1 and a Day 
0 will not be defined. 
The baseline period will be defined as the period from informed consent to the first study drug 
administration. The baseline value for a variable is defined as the last non-missing value 
collected before the first study drug administration. 
The endpoint value for efficacy variables is defined as the last non-missing value assigned to 
treatment for the subject. 
All variables planned to be measured at one or more time points and supposed to be time-related 
will be windowed.  
Coding Systems 
AEs and medical history terms will be assigned to a lowest level term (LLT) and a preferred 
term (PT) and will be classified by high level term (HLT), high level group term (HLGT) and 
primary system organ class (SOC) according to the MedDRA thesaurus. 
Concomitant medications will be classified according to active drug substance using the WHO 
drug dictionary. The generic name, the preferred name and the WHO name will be assigned.

In addition, the Anatomical Therapeutic Chemical (ATC) classes will be assigned to the drug ID. 
ATC codes are defined to the 4th level. For each medication, the primary ATC class will be 
assigned manually based on the generic name and the reason for use. 
Default Summary Statistics 
The default summary statistics for quantitative and ordinal variables will be the number of 
observations (n), mean, standard deviation (SD), median, minimum (Min) and maximum (Max) 
for subjects with data. Any other summary statistics will be described on an individual basis. 
Default Frequency Tabulations 
For qualitative variables, per category the numbers and frequencies of subjects with non-missing 
data (n, %) will be the default summary presentation, and if appropriate and present, the number 
of missing values. 
For AEs, medical history and concomitant medications, however, the denominator for the 
percentage calculation will be the number of subjects at risk for the particular treatment arm. A 
subject will be considered at risk if the subject is in the safety sample and entered the respective 
study period. 
Subject Listings 
Individual subject listings will be produced for all raw data and a selection of the derived data.  
10.2 
Subject Samples 
The main subject samples of interest are defined as follows. 
The all subjects consented sample will consist of all subjects who: 
- 
Gave their informed consent. 
 
The all subjects <allocated to treatment> sample will consist of all subjects who: 
- 
Were in the all subjects consented sample; and 
- 
Were <allocated to treatment>. 
 
The safety sample will consist of all subjects who: 
- 
Were in the all subjects allocated to treatment sample; and 
- 
Had at least one dose of study medication administered.

The full analysis (FA) sample will consist of all subjects who: 
- 
Were included in the safety sample; and 
- 
Had data for at least one post-baseline assessment of any efficacy measurement.  
 
The per-protocol (PP) sample will be defined through blind data review and will consist of all 
subjects who: 
- 
Were included in the FA sample; and  
- 
Did not present any major protocol violation. 
 
 
10.3 
Efficacy  
The primary efficacy variable is the duration (hours) of diarrhea (treatment duration max 5 days). 
Duration of diarrhea is defined as date of the evacuation of the last watery/diarrheal stool before 
recovery or end of treatment. 
 
The primary parameter, duration of diarrhea, will be analyzed using descriptive statistics. In 
addition, a Kaplan-Meier plot will be generated for which summary statistics will be presented as 
well.  
The secondary efficacy variables are 
• Time until recovery, defined as date and time of the evacuation of the first of two 
consecutive normal stools or no stool within 12 hours after the first normal stool. 
• Number of subjects recovered, in total and until each individual treatment day 
• Mean and median time until recovery  
• Assessment of treatment success by the physician: 
The assessment of treatment success by the physician will be done using the Global 
Physician Assessment. 
GPA score:  
1 = Complete relief of acute diarrhea,  
2 = marked improvement of acute diarrhea,  
3 = moderate improvement of acute diarrhea,  
4 = slight improvement of acute diarrhea,  
5 = no change in acute diarrhea,  
6 = worsening of acute diarrhea.  
Treatment will be rated as success when the GPA score equals 1 or 2. 
 
• Number of stools at baseline and per treatment day for toilet-trained subjects, only. 
• Number of watery stools per day for toilet-trained subjects, only.

Secondary efficacy parameters will be analyzed similarly to the primary analysis. All parameters 
will also be summarized using descriptive statistics. 
 
10.4 
Safety 
The safety sample will be used for the analysis of the safety and tolerability data. 
 
AEs are considered treatment emergent (TE) if they start or worsen at or after the first 
administration of study drug and before or on the day of last administration of study drug plus a 
gap period of 1 day. 
 
AEs will be reported on a per-subject basis, i.e. counting subjects rather than events. This means 
that if a subject suffers the same AEs repeatedly during the applicable study period, the event 
will be counted only once for that period. Repeated events per subject will be summarized 
according to the following rule: if a subject suffered the same AE more than once, the event will 
be assigned the worst severity, the closest relationship to the study drug and the earliest starting 
date. Only treatment emergent AEs will be reported. In the listings, however, all occurrences of 
the AEs will be presented. 
Treatment emergent AEs will be summarized per primary SOC, per HLT by primary SOC and 
per PT by HLT and primary SOC. Severity and drug-event relationship of treatment emergent 
AEs are summarized separately. Non-TEAEs will be listed. 
Vitals signs, including changes from baseline will be summarized. A frequency table will be 
presented for markedly abnormal values. 
10.5 
Other Assessments 
The assignment of subjects to subject samples, the disposition of subjects with respect to 
premature termination, reason for premature termination, drug exposure and treatment 
compliance will be summarized for the treatment group. 
Demographics and other baseline characteristics will be summarized for the treatment group. 
Medical history, including coding data will be summarized per primary SOC, per HLT by 
primary SOC and per PT by HLT and primary SOC. 
Major protocol deviations will be listed.

Determination of Sample Size 
In total, 40 subjects will be allocated to receive Racecadotril treatment, 20 subjects in each age 
group (< 24 months of age and ≥ 24 months of age). Results of a recently finalized study in 
Russian children showed that all children under Racecadotril treatment recovered within 3 days 
of drug treatment. A sample size of 40 subjects is sufficient to estimate a two-sided 95% 
confidence interval with the precision of 3.1 percentage points for a recovery of at least 99% of 
the subjects after 3 days of Racecadotril treatment. In order to account for drop-outs maximum 
48 subjects will be recruited. Recruitment will be stopped once 40 subjects have completed 
the study.

INVESTIGATOR OBLIGATIONS 
The Investigator agrees to conduct the clinical study in compliance with this protocol which was 
approved by the IEC/IRB in compliance with local regulatory requirements. The Investigator and 
the Sponsor will sign the protocol to confirm this agreement. 
11.1 
Essential Study Documents 
The Investigator is responsible for providing and maintaining essential study documents. 
Essential study documents are those documents that individually and collectively permit the 
evaluation of the conduct of the study and the quality of the data produced. These documents 
serve to demonstrate the compliance of the Investigator and the Sponsor (or an authorized 
representative) with the standards of GCPs and with all applicable national regulatory 
requirements. 
Essential study documents will include regulatory documents as well as source documents which 
are original documents, data and records of clinical findings, observations and other activities in 
a clinical study necessary for the reconstruction and evaluation of the study. Source documents 
will include hospital records, clinical and office charts, laboratory notes, memoranda, subject 
diaries or evaluation checklists, pharmacy dispensing records, recorded data from automated 
instruments, copies or transcriptions certified after verification as being accurate copies, 
microfiches, photographic negatives, microfilm or magnetic media, x-rays, subject files and 
records kept at the pharmacy, at the laboratories and at medical/technical departments involved 
in the clinical study. 
The Investigator agrees to allow direct access to all essential clinical study documents for the 
purpose of monitoring and/or auditing by the Sponsor (or an authorized representative) and 
inspection by the appropriate national and foreign regulatory authorities. 
11.2 
Case Report Form (CRF) Completion 
Data reflecting the subject’s participation with the study drug under investigation will be 
reported to the Sponsor (or an authorized representative). The data will be recorded on the 
designated (e)CRFs provided or approved by the Sponsor. 
The (e)CRF is essentially considered a data entry form and should not constitute the original (or 
source) medical records unless otherwise specified. Source documents are all documents used by 
the Investigator or hospital that relate to the subject’s medical history, that verify the existence of 
the subject, the inclusion and exclusion criteria and all records covering the subject’s 
participation in the study. They include laboratory notes, ECG results, memoranda, pharmacy 
dispensing records, patient files, etc. 
The Investigator is responsible for maintaining source documents. These will be made available 
for inspection by the study monitor at each monitoring visit. The Investigator must submit a

completed (e)CRF for each subject who did not fail screening. All supportive documentation 
submitted with the (e)CRF, such as laboratory or hospital records, should be clearly identified 
with the study and subject number. Any personal information, including subject name, should be 
removed or rendered illegible to preserve individual confidentiality. 
All data must be entered in English. The (e)CRFs should always reflect the latest observations on 
the subjects participating in the trial. Therefore, the (e)CRFs are to be completed as soon as 
possible after the subject’s eligibility has been confirmed and thereafter during or after the 
subject’s visit. To avoid inter observer variability, every effort should be made to ensure that the 
same individual who made the initial baseline determinations completes all efficacy and safety 
evaluations. The Investigator must verify that all data entries in the (e)CRFs are accurate and 
correct. If some assessments are not done, or if certain information is not available or not 
applicable or unknown, the Investigator should indicate this in the (e)CRF. The Investigator will 
be required to (electronically) sign off on the clinical data. 
The monitor will review the (e)CRFs and evaluate them for completeness and consistency. The 
(e)CRF will be compared with the source documents to ensure that there are no discrepancies 
between critical data. All entries, corrections and alterations are to be made by the responsible 
Investigator or his/her designee. The monitor is not allowed to enter data in the (e)CRFs. 
If additional corrections are needed, the responsible monitor or Data Manager will raise a query. 
The appropriate investigational staff will answer queries sent to the Investigator. 
In case screen failure data is entered in the (e)CRF, these data should be clearly indicated in the 
raw datasets and removed from the analysis datasets. 
 
11.3 
Essential Records Retention 
The Investigator should maintain the essential clinical study documents (including CRFs, source 
documents, clinical drug disposition records, signed subject informed consent forms, AE reports 
and other regulatory documents) as required by the applicable national regulatory requirements. 
The Investigator is to take adequate measures to prevent accidental or premature destruction of 
these documents. In the event of accidental destruction, the Investigator should notify the 
Sponsor (or an authorized representative) immediately. 
Essential clinical study documents will be retained at least two (2) years after the last approval of 
a marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region OR at least two (2) years have elapsed since the formal 
discontinuation of clinical development of the investigational product. These documents shall be 
retained for a longer period, however, if required by the applicable regulatory requirements or by 
an agreement with the Sponsor (or an authorized representative).

The Investigator is required to notify the Sponsor (or an authorized representative) prior to 
changing the location or status of any essential clinical study documents. The Sponsor (or an 
authorized representative) will be responsible for informing the Investigator as to when these 
documents no longer need to be retained. 
11.4 
Investigator Agreement 
The Investigator is responsible for assuring the proper implementation and conduct of the 
clinical study including those study-related duties delegated to other appropriately qualified 
individuals. The Investigator and his/her staff will cooperate with the Sponsor (or an authorized 
representative) during monitoring and auditing visits to assist with the review of the study data 
and resolve any discrepancies. 
The Investigator will demonstrate due diligence in recruitment and screening of potential study 
subjects. The enrollment rate should be sufficient to complete the study as agreed with the 
Sponsor (or an authorized representative). The Sponsor (or an authorized representative) is to be 
notified of any projected delays, which may impact the completion of the study. 
The Sponsor retains the right to terminate the clinical study at any time for any reason. In such 
an event, instructions on the requirements for the discontinuation of subjects will be provided by 
the Sponsor (or an authorized representative).

SPONSOR OBLIGATIONS 
12.1 
Protocol Amendments 
Only the Sponsor (or an authorized representative) will make modifications to the clinical study 
protocol, which will be documented in a written amendment that describes all changes that will 
be implemented. Protocol amendments will be categorized as either substantial or non-
substantial. 
Protocol amendments will be considered substantial when the changes have significant impact 
on: 
- 
The safety of physical or mental integrity of the subjects 
- 
The scientific value of the study 
- 
The conduct or management of the study 
- 
The quality or safety of any investigational medicinal product or control used in the study 
 
Protocol amendments will be considered non-substantial when the changes affect only 
administrative issues with the conduct of the study, i.e., changes in telephone numbers or 
addresses. 
The Sponsor (or an authorized representative) will be responsible for notifying the appropriate 
national regulatory authorities in writing of any amendments to the protocol prior to the changes 
being implemented except in those cases where the changes are necessary to eliminate an 
immediate hazard to the clinical study subjects. 
Substantial amendments will require written approval by the IEC/IRB prior to being 
implemented by the Investigator at the study site except under those circumstances described 
previously. Non-substantial amendments will not require approval by the IEC/IRB unless 
requested by the IEC/IRB. 
12.2 
Study Monitoring 
The study will be monitored by authorized representatives of the Sponsor throughout its duration 
by means of personal visits to the Investigator’s facilities and through other communications 
(e.g., telephone calls, written correspondence). Monitoring visits will be scheduled at mutually 
agreeable times periodically throughout the study and at frequency deemed appropriate for the 
study.  
These visits will be conducted to evaluate the progress of the study, ensure the rights and well-
being of the subjects are protected, check that the reported clinical study data are accurate, 
complete and verifiable from source documents, and the conduct of the study is in compliance 
with the approved protocol and amendments, GCPs and applicable national regulatory 
requirements. A monitoring visit will include a review of the essential clinical study documents

the clinical study records and resolve/document any discrepancies found during the visit. 
12.3 
Quality Assurance Audits 
The Sponsor’s (or an authorized representative’s) Quality Assurance department may conduct
