PROTOCOL SYNOPSIS 
3.1 
Rationale 
This study is being conducted to assess the effectiveness of the Compound Sodium Alginate 
Double Action Chewable Tablets compared to placebo on acidic reflux events into the 
esophagus in patients diagnosed with GERD. 
 
3.2 
Objective(s) 
The primary objective of this study is to compare the time during the 4 hour post dosing 
period where the pH is below pH 4 for Compound Sodium Alginate Double Action Chewable 
Tablets versus matching placebo tablets. 
The secondary objectives of this study are to determine and compare the number of 
occasions and percentage of time during the 1 and 4 hour post dosing period when pH falls 
below pH 4 and pH 5.  Other secondary objectives include comparing the longest reflux time 
and DeMeester scores during the 4 hour period. 
 
3.3 
Primary Endpoint 
The primary efficacy endpoint will be the percentage of time during the 4 hour post dosing 
period with pH below pH 4 for Compound Sodium Alginate Double Action Chewable Tablets 
versus matching placebo tablets. 
 
3.4 
Secondary Endpoints 
The following secondary endpoints will also be evaluated: 
• 
Percentage of time during the 4 hour post dosing period with pH below pH 5 
• 
Number of occasions during the 4 hour post dosing period when pH falls below pH 4 
• 
Number of occasions during the 4 hour post dosing period when pH falls below pH 5

Design Summary 
This is a multi-centre, randomised, open-label, placebo-controlled, two-period crossover 
study.  After signing a written informed consent, patients will undergo a screening period of 
up to 10 days.  Patients who satisfy the study entry requirements within 10 days of consent, 
will be randomised to receive either four Compound Sodium Alginate Double Action 
Chewable Tablets or four matching placebo tablets following placement of a pH electrode 
and a standardised refluxogenic meal.  
Upon completion of the 4-hour post-dose pH monitoring period patients will be instructed to 
begin taking supplied Compound Sodium Alginate Double Action Chewable Tablets (two 
tablets four times daily) for 7 days. Patients will return after the 7 day period for repeat 
catheter insertion and pH monitoring, receiving the alternative randomised treatment. 
 
3.6 
Sample Size 
The number of patients enrolled for this study has been derived from experience of previous 
pH monitoring studies conducted with other Gaviscon® formulations. It is anticipated that 36 
evaluable patients will be required to complete the study. In order to achieve this, 44 patients 
will be enrolled in this study. 
 
3.7 
Anticipated Study Timings 
It is estimated that the clinical phase of this study will commence in May 2013 and last a 
period of 6-9 months. 
The duration of each patient’s participation in the study will be a maximum of 19 days (from 
screening visit to end of treatment visit) and involve 3 visits.

Statistics 
All statistical tests will be conducted using two-tailed tests at the 5% significance level. 
The null hypothesis at all times will be the equality of the fixed effect being compared from 
the model. 
The primary endpoint will be analysed primarily using an ANOVA of variance model with 
treatment, dosing visit treatment sequence as fixed effects and patient nested within 
treatment sequence as a random effect. The difference between treatment least square 
means will be used to represent the treatment differences. The effects for dosing visit and 
treatment sequence will also be assessed. A residual analysis will be performed. If there is a 
major departure from the assumptions of normality, independence or heteroscedasticity of 
residuals, then further analysis using transformed data will be used to support the original 
model results. If such assumptions still do not hold following an appropriate transformation 
then Wilcoxon Rank-Sum test will be used to compare the dosing visit difference (dosing 
visit 1 – dosing visit 2) between treatment sequence groups to represent the treatment 
comparison. 
All secondary endpoints will be analysed identically to the primary endpoint. 
All secondary endpoints and sensitivity or alternate analyses for the primary endpoint will 
serve as supportive evidence for the primary analysis only and therefore no adjustment for 
multiple comparisons will be made. 
If less than 2 hours post-dosing monitoring data is available, for whatever reason, (or less 
than 1 hour post-dosing data within the first hour for parameters based on the first hour post-
dosing) the derived parameters will be considered missing.  If 2 or more hours post-dosing 
monitoring data is available, the parameters will be derived using the data available, and will 
be adjusted, where necessary, by multiplying by the factor (4 hours / time with data 
available).  Any data recorded more than 4 hours post-dosing will be ignored when deriving 
these parameters.

INTRODUCTION 
Gastro-esophageal reflux disease (GERD) is a condition that develops when the backward 
movement of stomach contents into the esophagus causes troublesome symptoms and/or 
complications. The troublesome symptoms of GERD can have significant impact on health-
related quality of life and work productivity [1-4].  GERD is believed to be the most common 
upper gastro-intestinal condition, affecting between 10% and 20% of the Chinese population 
and the prevalence of GERD in Asia is reported to be approximately 5% [5]. 
Dyspepsia (sometimes referred to by the non-medical term indigestion) is defined as pain or 
discomfort centred in the upper abdomen. It is often described as a feeling of fullness, 
bloating, nausea, heartburn or gassy discomfort in the chest or abdomen. 
Heartburn and regurgitation are the two most predominant clinical manifestations of GERD 
[6]. The pain is usually burning in character and felt retrosternally, rising from the epigastrium 
towards or into the throat.   
The over-the-counter (OTC) preparations for treatment of heartburn in China include 
antacids, proton pump inhibitors (PPIs) and histamine H2-receptor antagonists as well as 
traditional Chinese medicines.  While PPIs are effective in acid-related conditions, they offer 
limited benefit for patients with functional dyspepsia and/or functional heartburn [6-8]. 
Compound Sodium Alginate Double Action Chewable Tablets (also known as Gaviscon® 
Double Action Tablets) are a combination of two antacids (calcium carbonate and sodium 
bicarbonate) and an alginate. On ingestion, the product reacts rapidly with gastric acid to 
form a raft of alginic acid gel having a near neutral pH and which floats on the stomach 
contents effectively impeding gastro-esophageal reflux. 
Calcium carbonate neutralises gastric acid to provide fast relief from indigestion and 
heartburn. This effect is increased by the addition of sodium bicarbonate which also has a 
neutralising action. The total neutralising capacity of four tablets is approximately 20 mEqH+. 
A similar study was previously conducted in China to demonstrate the effect of Gaviscon® 
Original Liquid on esophageal pH in GERD patients [9]. No clinical studies have been 
performed with Compound Sodium Alginate Double Action Chewable Tablets to 
demonstrate the effect on esophageal pH in patients with GERD.  This study is being 
conducted to provide evidence for inclusion in applications to regulatory authorities that 
Compound Sodium Alginate Double Action Chewable Tablets are effective for the treatment 
of reflux in patients diagnosed with GERD.

The potential risks to patients taking part in the present study are considered to be low.  
Endoscopy and placement of the pH catheter can cause discomfort but the risks associated 
with these procedures are considered to be low.  The adverse reactions that occur very 
rarely (<1/10,000) as a result of taking Gaviscon® products are allergic manifestations such 
as urticaria or bronchospasm, anaphylactic or anaphylactoid reactions as a result of a 
patient being sensitive to any of the active substances (sodium alginate, sodium bicarbonate 
and calcium carbonate) or any of the excipients.  Other adverse reactions include:  
1. Sodium bicarbonate – increased plasma sodium levels especially for those with renal 
and cardiovascular conditions on a highly restricted salt diet. 
2. Calcium carbonate – high doses of calcium may cause alkalosis, hypercalcaemia, 
acid rebound, milk alkali syndrome or constipation. 
For this reason, the risk benefit balance for the current study is considered to be acceptable. 
This study will be conducted in accordance with the principles set out in the Declaration of 
Helsinki. It will comply with International Conference on Harmonisation (ICH) Good Clinical 
Practice (GCP) and applicable regulatory requirements.

STUDY RATIONALE 
This study is being conducted to assess the effectiveness of the Compound Sodium Alginate 
Double Action Chewable Tablets compared to placebo on acidic reflux events into the 
esophagus in patients diagnosed with GERD. 
 
8 
STUDY OBJECTIVES 
The objective of this study is to demonstrate that Compound Sodium Alginate Double Action 
Chewable Tablets are statistically significantly superior to matching placebo tablets in the 
suppression of gastric reflux provoked by a standard refluxogenic meal in GERD patients. 
Gastric reflux will be assessed by ambulatory esophageal pH monitoring over 4 hours. 
The purpose of this study is to compare esophageal pH profiles monitored during the 
4-hours after ingestion of a refluxogenic test meal, followed by a single dose of study 
medication. Patients recruited to the study will attend the clinic on two occasions separated 
by 7 days, and at each visit they will consume a refluxogenic meal; 30 minutes later the 
patient will be randomised to receive either a dose of either four Compound Sodium Alginate

Double Action Chewable Tablets or four matching placebo tablets. On each occasion 
esophageal pH will be monitored for 4 hours post dosing.  Each patient will be his/her own 
control. Between the pH monitoring visits, patients will take Compound Sodium Alginate 
Double Action Chewable Tablets, two tablets 4 times daily for 7 days, to provide ongoing 
symptom relief.  
 
8.1 
Primary Objective 
The primary objective of this study is to compare the time during the 4 hour post dosing 
period where the pH is below pH 4 for Compound Sodium Alginate Double Action Chewable 
Tablets versus matching placebo tablets.

Design Summary 
This is a multi-centre, randomised, open-label, placebo-controlled, two-period crossover 
study.  After signing a written informed consent, patients will undergo a screening period of 
up to 10 days.  Patients who satisfy the study entry requirements within 10 days of consent, 
will be randomised to receive either four Compound Sodium Alginate Double Action 
Chewable Tablets or four matching placebo tablets following placement of a pH electrode 
and a standardised refluxogenic meal.  
Upon completion of the 4-hour post-dose pH monitoring period patients will be instructed to 
begin taking supplied Compound Sodium Alginate Double Action Chewable Tablets (two 
tablets four times daily) for 7 days. Patients will return after the 7 day period for repeat 
catheter insertion and pH monitoring, receiving the alternative randomised treatment.   
 
9.3 
Discussion of Study Design 
Esophageal pH monitoring is a well validated and accepted technique for diagnosis of 
gastro-esophageal reflux disease (GERD). It provides direct physiologic measurement of 
acid in the esophagus and can assess the response of the disease to treatment.   In this 
study it is being used to assess and compare the effects of Compound Sodium Alginate 
Double Action Chewable Tablets and matching placebo tablets on pH over a 4 hour post-
dose period 30 minutes after a refluxogenic meal.

A crossover design is used for this study where the patient has pH measurement for four 
hours after four Compound Sodium Alginate Double Action Chewable Tablets and four 
matching placebo tablets on two separate occasions.  A 7-day washout period occurs 
between each pH monitoring visit; all patients will receive standardised treatment consisting 
of Compound Sodium Alginate Double Action Chewable Tablets (two tablets four times 
daily) for their symptoms of GERD during during this washout period between pH monitoring 
visits. 
 
9.4 
Number of Patients 
The number of patients enrolled for this study has been derived from experience of previous 
pH monitoring studies conducted with other Gaviscon formulations. It is anticipated that 36 
evaluable patients will be required to complete the study. In order to achieve this, 44 patients 
will be enrolled in this study. 
Further details are provided in Section 14.1. 
 
9.5 
Study Duration 
It is estimated that the clinical phase of this study will commence in May 2013 and last a 
period of 6-9 months. 
The duration of each patient’s participation in the study will be a maximum of 19 days (from 
screening visit to end of treatment visit) and involve 3 visits. 
Patients can enter the study, if eligible, as soon as all screening results are available 
following informed consent at Visit 1. A maximum of 10 days will be allowed to screen a 
patient at Visit 1. If eligible, the patient will be randomised and will commence the first pH 
monitoring period at Visit 2 (Day 0).  The patients will be randomised to receive either four 
Compound Sodium Alginate Double Action Chewable Tablets or four matching placebo 
tablets 30 minutes after a refluxogenic meal with pH monitored and recorded for a 4-hour 
period post-dose. 
All patients will then receive Compound Sodium Alginate Double Action Chewable Tablets 
(two tablets four times daily) as Non-investigational Medicinal Product (NIMP) for 
symptomatic treatment.  Patients will stop Compound Sodium Alginate Double Action 
Chewable Tablets 24 hours prior to returning for Visit 3 which occurs 7 ± 2 days later. The 
patient will receive the alternate treatment after a refluxogenic meal with pH monitored and 
recorded for a 4-hour period post-dose.

The anticipated overall duration of study conduct will be between 6 and 9 months.  
 
9.6 
Patient Commitment to the Study 
The duration of each patient’s participation in the study will be up to 19 days (from screening 
visit to final visit). The initial screening visit (Visit 1) will be followed by two visits (Visits 2 and 
3) at which the patient will consume a refluxogenic meal, followed 30 minutes later by a dose 
of either four Compound Sodium Alginate Double Action Chewable Tablets or four matching 
placebo tablets (as randomised); esophageal pH will be monitored continuously from 30 
minutes prior to dosing to 4 hours post dosing.  The study will be completed with post-study 
assessments after the second pH monitoring visit. 
 
9.6.1 
Duration of Patient Participation 
Up to 10 days will be allowed to screen a patient at Visit 1 following informed consent. The 
pre-study procedures will consist of a medical history and physical examination, 12-lead 
ECG, endoscopy diagnostic examination (endoscopy’s conducted prior to consent may be 
used if patients were examined within 28 days of giving consent if the examination was 
conducted at the same hospital), haematology and clinical chemistry and urine pregnancy 
test for female patients of child-bearing potential. 
Visit 2 (Day 0) will take place immediately after all screening results are available and within 
10 days after Visit 1. Patients meeting the entry criteria will be randomised to receive either 
four Compound Sodium Alginate Double Action Chewable Tablets or four matching placebo 
tablets administered following placement of a pH electrode (using manometry to position the 
pH electrode) and 30 minutes after a standardised refluxogenic meal. pH will be measured 
for 4 hours post-dose. 
The patient will then be issued with Compound Sodium Alginate Double Action Chewable 
Tablets (two tablets four times daily) to take for 7 + 2 days, stopping dosing at least 24 hours 
prior to Visit 3. 
At Visit 3, End of treatment period (Day 7 ± 2 days), unused investigational medicinal 
product (IMP) will be collected.  The patient will receive the alternate treatment following 
placement of a pH electrode and 30 minutes after a standardised refluxogenic meal.  pH will 
be measured for 4 hours post-dose followed by a final assessment for safety (AEs, 
haematology and clinical chemistry with urine pregnancy test for female patients and 
physical examination).

Further details on the timing of study visits are provided in Section 11.2. 
 
9.6.2 
Invasive Procedures 
Blood samples will be taken for haematology and clinical chemistry at Visit 1 and Visit 3.  
The total volume of blood samples will not exceed 30 ml. 
An endoscopy will be performed at screening or results may be used if conducted prior to 
consent within 28 days of giving consent if the examination was conducted at the same 
hospital. 
pH reflux monitoring for a period of 4.5 hours will take place on two occasions.  This requires 
placement of the pH monitoring probe via one nostril, down the back of the throat, and into 
the esophagus as the patient swallows. Esophageal manometry is used to guide the 
accurate placement of the pH electrodes. 
Further details on the study assessments are provided in Section 11.2. 
 
9.6.3 
General and Dietary Restrictions 
Patients will be instructed to follow their routine meal pattern, avoiding food not normally 
consumed, such as excessively spicy food. There should be an interval of at least three 
hours between meals. 
The patient will be asked to abstain from alcohol 24 hours prior to each test meal and to fast 
for a minimum of 4 hours prior to placement of the pH electrodes. 
The patient will be asked not to take any treatment for GERD symptoms for 24 hours prior to 
each test meal. 
 
9.7 
End of Study

contraceptives; approved hormonal implants or topical patches; intrauterine devices; barrier 
methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with 
spermicidal foam/gel/film/cream/suppository; true abstinence (true abstinence: when this is 
in line with the preferred and usual lifestyle of the patient. Periodic abstinence e.g., calendar, 
ovulation, symptothermal, post-ovulation methods and withdrawal are not acceptable 
methods of contraception. Should the patient become sexually active while participating in 
the study, she must agree to use a double barrier method or condoms/diaphragms with 
spermicidal foam/gel/film/cream/suppository). Patients are to be informed that a female 
condom and male condom should not be used together as friction between the two can 
result in either product failing. A woman of childbearing potential is defined as any female 
who is less than 2 years post-menopausal or who has not undergone a hysterectomy or 
surgical sterilisation, e.g. bilateral tubal ligation, bilateral ovariectomy (oophorectomy). 
The procedures to be followed if a patient becomes pregnant while enrolled in the study are 
described in Section 13.3.

Baseline Visit 
11.3.1 
Screening/Enrolment Procedures 
Potential patients will be provided with the patient information sheets and given ample time 
to read and decide whether they are interested in taking part in the study. If the patient is 
interested, she/he will speak to the investigator or person delegated by the investigator to 
take consent who will explain more about the study and answer any questions. If the patient 
feels fully informed and willing to participate in the study they will complete, sign and date 
the informed consent form (ICF). The ICF will then be counter signed and dated by the 
investigator or person delegated by the investigator  to take consent. A copy of the ICF and 
patient information sheet will be provided to the patient for their personal records. 
All patients will be given a 4-digit screening number once they have provided consent. The 
first two digits will refer to the centre number and the second two digits to the number of 
patients screened at that centre. For example, screening numbers at centre 01 will start 
0101, 0102 etc.  
The screening process can take up to a maximum of ten days after informed consent.

11.3.2.1 
Clinical Assessments at Visit 2 
Visit 2 will take place up to 10 days after Visit 1. It can be the same day as Visit 1 but will 
only occur on the same day as Visit 1 if the patient meets all criteria with respect to use of 
concomitant medication, abstention from alcohol, fasting etc.  
At Visit 2 patients will return to the clinic to have any medical history changes during the 
screening period and concomitant medications recorded; any adverse events noted during 
the pH monitoring session will be recorded. If the patient fulfils the eligibility criteria for 
randomisation, a unique 3-digit randomisation number will be allocated and study medication 
dispensed (001, 002 etc.). The randomisation number will be pre-printed on the medication 
assigned to that patient. Randomisation numbers will not be site-specific. The numbers 
available at a site have to be allocated to the patients in consecutive order.

Eligible patients will undergo the following pH monitoring procedure: 
4-hour pH monitoring 
1) Patients will be required to fast for a minimum period of 4 hours prior to insertion 
of the manometric probe used to transfer the pH electrode. 
2) The basic equipment requirements for ambulatory esophageal pH studies are a 
portable data logger for data storage, a pH electrode, a computer and software for 
analysis of pH data. 
3) The probe and pH electrode will be passed through a nostril; manometry will be 
used to ensure the pH electrode is correctly positioned 5 cm above the superior 
margin of the lower esophageal sphincter (LES) and then taped to the face to hold 
it in place. 
4) 30 minutes after the procedure patients will receive a standardised reflux 
provoking meal (Section 12.5); patients will be allowed 30 minutes to consume the 
entire meal. After consumption of the meal the pH monitoring data logger will be 
activated and recording will continue until 4 hours post-dose. 
5) 30 minutes after completing the meal patients will receive their randomised single 
dose of study medication, either four Compound Sodium Alginate Double Action 
Chewable Tablets or four matching placebo tablets.  
6) Patients will remain in the clinic for the duration of the pH monitoring period, under 
supervision. They will be allowed to sit or stand during the pH monitoring period 
but will be encouraged not to lie down.  
7) Volunteers will not be permitted to eat or drink anything other than the test meal 
from the start of the fasting period until the end of the first dosing visit. 
8) Upon completion of the monitoring period patients will be given a prescribing card 
which they will use to collect their symptom control medication, Compound 
Sodium Alginate Double Action Chewable Tablets, from a dispensing unit.  
Sufficient medication will be dispensed to allow 8 days usage. Patients will be 
instructed to begin taking their Compound Sodium Alginate Double Action 
Chewable Tablets later that same day (typically the evening of Visit 2) and 
continue until their last dose 24 hours prior to their next visit. Patients will be 
instructed to follow their routine meal pattern, avoiding food not normally 
consumed, such as excessively spicy food. There should be an interval of at least 
three hours between meals. They will be instructed to take bring all medication 
with them to the clinic when they return for Visit 3. 
9) Patients will be questioned about adverse events ("How have you been feeling 
today?").  Any adverse events reported in response to this question or otherwise 
spontaneously reported by the volunteer or observed by the study personnel at 
any point during study procedures will be recorded in the patient’s CRF.

11.3.2.2 
Clinical Assessments at Visit 3 
Patients will arrive at the hospital 7 + 2 days after the last visit.  At Visit 3 the Investigator 
will: 
1) Record any concomitant medications and adverse events occurring since the last 
visit; 
2) The Investigator will conduct 4-hour pH monitoring (see section 11.3.2.1 4-hour 
pH monitoring for procedure and fasting requirements). At this second dosing 
visit, the patient will receive the alternate randomised study treatment (four 
Compound Sodium Alginate Double Action Chewable Tablets or four matching 
placebo tablets).  
3) 4-hour pH monitoring data will be collected from Visit 3. The Investigator will 
record any additional adverse events and concomitant medications at the end of 
the visit.  
4) All medication, used and unused blister packs, will be returned to the drug 
dispensing unit.

Study Variables and Methods of Assessment 
11.4.1 
Efficacy Variables 
11.4.1.1 
Overview of Efficacy Variables 
The primary and some secondary efficacy variables are derived from the 4-hour pH 
monitoring sessions following four Compound Sodium Alginate Double Action Chewable 
Tablets or four matching placebo tablets. 
 
11.4.1.2 
Methods of Assessment of Efficacy Variables 
Efficacy is assessed by esophageal pH monitoring following a standard refluxogenic test 
meal.  A single dose of the study treatment is administered 30 minutes after completion of 
the meal and pH measurements recorded for 4 hours post-dose.  Patients will be 
randomised to receive four Compound Sodium Alginate Double Action Chewable Tablets or 
four matching placebo tablets and one week later will receive the alternate treatment. 
 
11.4.2 
Appropriateness of Measurements 
Esophageal pH monitoring is a well validated and accepted technique for diagnosis of 
gastro-esophageal reflux disease (GERD). It provides direct physiologic measurement of 
acid in the esophagus and can assess the response of the disease to treatment. In this study 
it is being used to assess and compare the effects of four Compound Sodium Alginate 
Double Action Chewable Tablets and four matching placebo tablets on pH over a 4 hour 
post-dose period 30 minutes after a refluxogenic meal. 
A crossover design is used for this study where the patient has pH measurement after 
Compound Sodium Alginate Double Action Chewable Tablets and matching placebo tablets 
on two separate occasions.  A 7-day washout period occurs between each pH monitoring 
visit; all patients will receive standard treatment, Compound Sodium Alginate Double Action 
Chewable Tablets (two tablets four times daily), for their symptoms of GERD during this 
washout period between pH monitoring visits.

• 
Reason for unscheduled visit 
• 
Any AEs. 
• 
Concomitant therapy changes. 
• 
Withdrawal (if deemed appropriate). 
• 
Any clinical assessments deemed appropriate for the clinical care of the patient. 
If the dosage regimen of study medication has been changed, the Investigator must contact 
the RB Clinical Project Manager in order to determine if the patient should be withdrawn 
from the study or may be allowed to continue. The Clinical Project Manager will advise the 
Investigator of how information should be recorded on the CRF. 
Unscheduled visits should not alter the timing of the routine study schedule. 
 
11.7 
Patient Withdrawal and Replacement Criteria 
11.7.1 
Patient Withdrawal 
The Investigator may withdraw the patient from the study at any time. Reasons for removing 
a patient from the study include, but are not limited to: 
• 
AEs that in the judgement of the Investigator may cause severe or permanent harm 
(significant clinical deterioration is an AE). 
•

Accountability of Investigational and Non-Investigational 
Medicinal Product(s) 
The Investigator will keep all IMP(s) and NIMP(s) in a pharmacy or a secure storage facility, 
accessible only to those individuals authorised by the Investigator to dispense the 
medication. 
The Investigator or designated individual will maintain an inventory. This will include the 
description and quantity of IMP(s) and NIMP(s) received during the course of this study, as 
well as a record of the materials that are dispensed and returned (how much, to whom, and 
when). This inventory (“Drug Dispensing Log”) will be subject to review by the study monitor 
during monitoring visits. 
The Investigator agrees not to supply IMP(s) and NIMP(s) to any person except study 
personnel and patients enrolled in this study. 
All IMP(s) and NIMP(s) should be stored between 4°C and 30°C. Temperatures must be 
monitored using a minimum / maximum thermometer and recorded in a temperature log on 
working days. 
 
12.9 
Disposal of Unused Investigational and Non-Investigational 
Medicinal Product(s) 
The Investigator agrees to conduct a drug supply inventory, to record the results of this 
inventory (“IMP/NIMP Removal from Site” form) and to return it and all original IMP/NIMP 
containers, whether empty or containing IMP or NIMP, to 
 at the end of the study or 
in stages during the course of the study. 
 and RB will arrange for the appropriate and timely destruction of all returned IMP(s) 
and NIMP(s) following the end of the study (on finalisation of the study report).

Concomitant Therapies 
Concomitant therapies are defined as prescribed medications, physical therapies, and over-
the-counter preparations, including herbal preparations licensed for medicinal use, other 
than IMP(s) and NIMP(s) that the patient receives during the course of the study. 
The Investigator will record any medications given for treatment of AEs on the concomitant 
medication page in the patient’s CRF. Any medication taken by the patient from the time of 
giving informed consent through to the end of the study should also be recorded in the CRF. 
Any changes in concomitant therapy during the study will be documented, including 
cessation of therapy, initiation of therapy, and dose changes. 
 
12.11 
Prohibited Therapies 
The use of the following therapies will not be permitted: 
 
PPIs during the 10 days prior to screening and throughout the study. 
 
Prokinetics or H2 antagonists during the 5 days prior to screening and throughout the 
study. 
 
Systemic glucocorticosteroids or non-steroidal anti-inflammatory drugs (NSAIDs except 
low dose aspirin given for cardioprotection) on more than 3 consecutive days in the 28 
days prior to screening and are not allowed throughout the study. 
 
PPI-based triple or quadruple therapy for eradication of H-pylori during the 28 days prior 
to screening and throughout the study. 
 
Mucous membrane protection drugs for 5 days prior to screening and throughout the

SAFETY ASSESSMENTS 
13.1 
Adverse Events 
13.1.1 
Adverse Event Definitions 
Adverse Event (AE): Any untoward medical occurrence in a patient participating in a clinical 
study administered an IMP, which does not necessarily have a causal relationship with 
administration of the IMP. 
Comment: An AE can therefore be any unfavourable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease temporally associated with the use of an 
IMP, whether or not considered related to the IMP. 
AEs do not include the following: 
• 
Medical or surgical procedures; the condition requiring a medical or surgical procedure is 
an AE. 
• 
Elective surgery or pre-existing conditions requiring planned procedures outside the 
scope of the study. 
Adverse Reaction (AR) to an IMP: All untoward and unintended responses to an IMP 
related to any dose administered. 
Comment: All AEs judged by either the Investigator or the sponsor as having a reasonable 
causal relationship to an IMP qualify as ARs. The expression “reasonable causal 
relationship” means to convey in general that there is evidence or argument to suggest a 
causal relationship. 
Serious Adverse Event (SAE): Any untoward medical occurrence (i.e. AE) that at any 
dose:

• 
Results in death. 
• 
Is life-threatening. 
• 
Requires hospitalisation or prolongation of existing hospitalisation. 
• 
Results in persistent or significant disability/incapacity. 
• 
Is a congenital anomaly/birth defect. 
• 
Is otherwise considered to be medically significant. 
Comments: Life-threatening in the definition of an SAE or serious AE refers to an event in 
which the patient 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. 
Medical judgement should be exercised in deciding whether an AE or AR is otherwise 
considered to be medically significant. Important AEs or ARs that are not immediately life-
threatening or do not result in death or hospitalisation but may jeopardise the patient or may 
require intervention to prevent 1 of the other outcomes listed in the definition above should 
also be considered serious. 
Examples of such medically significant events are: 
• 
Intensive treatment in an emergency room or at home for allergic bronchospasm. 
• 
Blood dyscrasias or convulsions that do not result in hospitalisation. 
• 
Development of drug dependency or drug abuse. 
Unexpected Adverse Reaction: An AR, the nature or intensity of which is not consistent 
with the applicable product information (e.g. Investigator Brochure for an unauthorised IMP 
or SmPC for an authorised IMP). 
Comment: When the outcome of the AR is not consistent with the applicable product 
information this AR should be considered as unexpected. 
Suspected Unexpected Serious Adverse Reaction (SUSAR): An SAE considered to have 
a causal relationship with administration of the IMP, and the nature or intensity of which is 
not consistent with the applicable product information (e.g. Investigator brochure for an 
unauthorised IMP or SmPC for an authorised IMP).

Intensity:  The term “severe” is often used to describe the intensity (severity) of a specific 
event.  This is not the same as “serious”, which is based on patient/event outcome or action 
criteria. 
 
13.1.2 
Observation Period for Adverse Event Reporting 
The observation period for an individual patient will start after giving informed consent and 
will finish at the last visit defining the end of the study for the given individual patient.  
Any SAEs occurring after Informed Consent must be reported. 
Any untoward medical events occurring after Informed Consent but prior to IMP 
administration should be recorded in the patient’s medical history and not reported as an AE. 
 
13.1.3 
Information to be Collected on Adverse Events 
Each AE will be recorded according to the criteria given below. “Relationship to IMP” must 
be determined by the Investigator (if medically qualified) or by a medically qualified Co-
Investigator.

Definition 
AE reported 
term 
 
Any untoward medical occurrence in a patient 
administered an IMP and which does not 
necessarily have to have a causal relationship with 
this treatment. 
An AE can therefore be any unfavourable and 
unintended sign (including an abnormal laboratory 
finding, for example), symptom, or disease 
temporally associated with the use of a medicinal 
product, whether or not considered related to the 
IMP.

Date of 
change in 
severity of AE 
 
The date on which the AE changed in severity. 
This date equates to the finish date of the old 
severity and the onset date of the new severity. 
Intensity 
 
Intensity will be determined by the Investigator. For 
symptomatic AEs the following definitions will be 
applied, but medical experience and judgement 
should also be used in the assessment of intensity. 
 
Mild 
The AE does not limit usual activities; the patient 
may experience slight discomfort. 
 
Moderate 
The AE results in some limitation of usual 
activities; the patient may experience significant 
discomfort. 
 
Severe 
The AE results in an inability to carry out usual 
activities; the patient may experience intolerable 
discomfort or pain. 
Actions taken 
None 
No action was taken in relation to this AE. 
 
IMP dose changed 
The dose of IMP was changed due to this AE, i.e. 
increase, decrease, or temporary discontinuation. 
 
IMP permanently 
discontinued 
The IMP was permanently discontinued due to this 
AE. 
 
Symptomatic therapy 
Symptomatic therapy was added or changed due 
to this AE. 
 
Patient hospitalised 
or hospitalisation 
prolonged 
The patient was hospitalised or hospitalisation was 
prolonged due to this AE. 
 
Other action (specify)
Other action was taken due to this AE, e.g. 
diagnostic tests, laboratories and procedures.

13.1.4 
Procedure for Reporting Adverse Events 
All AEs that arise after the patient has had IMP administered will be recorded in the patient’s 
CRF. AEs can be reported spontaneously by the patient or in response to non-leading 
questioning or observation by the Investigator, or be a significant laboratory abnormality. 
The Investigator will ask the patient: “Are you experiencing any symptoms or complaints?” at 
the baseline visit and “Have you had any symptoms or complaints since the last visit?” 
during the study.  
Assessments of the relationship of AEs to IMP must be made by the Investigator (if 
medically qualified) or by a medically qualified Co-Investigator. 
 
13.1.5 
Procedure for Reporting Serious Adverse Events 
In the event of a Serious Adverse Event (SAE), the Investigator should telephone the Clinical 
Project Manager (CPM) within 24 hours of knowledge of the event. The name and contact 
number of the CPM will be provided to the Investigator in the study protocol and/or at the 
Study Initiation Visit. To allow timelines to be met the Investigator can report the event to the 
Global Vigilance Group (GVG) simultaneously by contacting GVG by email: 
. 
The CPM will also forward any SAE information/forms to the RB Global Vigilance Group 
within the same day using the email address: 
.  
Out of hours emergency contacts will be provided to the Investigator in the study protocol 
and/or at the Study Initiation Visit. If notification is via telephone the CPM will ensure that a 
SAE Form is completed but the Investigator will be requested to make a detailed written 
report by sending a follow-up SAE Form as soon as possible. The CPM will be responsible 
for reporting the event to the Global Vigilance Group (
). All the SAE forms will 
be provided to the CPM function via email, and a copy filed in the TMF. Any inconsistencies 
in the information received from the Investigator will be clarified using the Adverse Event 
Data Clarification Form.  
If the case does require reporting, a CIOMS (Council for International Organizations of 
Medical Sciences) form will be produced. A copy of this will be sent to the RB Drug Safety 
Officer (DSO) in China who will complete the SFDA SAE Form in Chinese and submit to the 
SFDA within 7 days for fatal or life-threatening events, or 15 days for all events. 
If the event requires expedited reporting (event classified as a SAE):

1. The IEC/IRB, SFDA and PFDA will be notified by the Investigator within 24 hours of 
awareness 
2. All other investigators participating in the study will be informed by the CPM 
The Investigator will be instructed to retain a copy of all the SAE Forms in the Investigator 
Site File, and must inform his/her local ethics committee/institutional review board of all 
SAEs occurring in the study. 
The Investigator should not break the randomisation code except when it is necessary to do 
so in order to ensure the patient receives appropriate medical care (see Section 12.2). 
The overall procedure for reporting SAEs is illustrated in the flowchart below.

13.1.7 
Follow-up of Patients Experiencing Adverse Events upon 
Completion of the Study or Withdrawal from the Study 
All SAEs, and all AEs that cause premature withdrawal of the patient from the study, that 
have not resolved by the end of the study will be followed up by the Investigator until 
resolution or until the Investigator believes there will be no further change. This may involve 
the patient making additional visits to the site. 
All other AEs will be followed up where possible to resolution or until the Investigator 
believes there will be no further change, whichever is the earlier.  
The minimum data required are the final outcome and date, which may be obtained by the 
Investigator in a documented telephone conversation with the patient or patient’s medical 
practitioner. 
 
13.1.8 
Procedures for Patients Experiencing Onset of Adverse Events 
after End of the Study 
As the active study drug in this study is not absorbed, a serious adverse event that occurs 
within a day of the final dose of study medication should be reported and followed to 
resolution or until the Investigator believes there will be no further change. 
 
13.2 
Overdose 
Overdoses are reportable to RB irrespective of the presence of an associated AE/SAE. The 
overdose and any associated AE/SAE will be captured on an AE CRF page/SAE form. 
 
13.3 
Pregnancy 
If a patient is found to be pregnant after being dosed with IMP: 
• 
Promptly notify RB (i.e. Clinical Project Manager) or CRO monitor (if CRO is 
Investigator’s first port of call for reporting SAEs).  
• 
Withdraw the patient from the study.

The laboratories will be requested to provide documented evidence of GCLP compliance. 
This may be a statement of compliance issued by the appropriate national authority, or 
details of accreditation by a recognised organisation. 
An independent inspection of the laboratories by 
 or RB may be conducted. 
 
13.5 
Vital Signs, Physical Findings and other Observations Related to 
Safety 
Vital signs and physical examinations will be conducted at baseline and final or early 
termination visits. A 12-lead ECG and endoscopy will be conducted and the results will be 
reviewed by the investigator at baseline as part of the screening procedures. Patients will be 
asked about adverse events at follow-up visits.

STATISTICAL CONSIDERATIONS 
The statistical analysis will be undertaken in collaboration with Quintiles. 
A detailed Statistical Analysis Plan will be finalised before the database is locked and prior to 
analysis of the study being carried out.  
Any deviations from the analyses described below will be included in the Statistical Analysis 
Plan, which will form Appendix 16.1.9 of the clinical study report. 
 
14.1 
Sample Size Justification 
No statistical justification for the sample size in this study was performed because the 
variance of the response is not known for Compound Sodium Alginate Double Action 
Chewable Tablets. 
The number of patients enrolled for this study has been derived from experience of previous 
pH monitoring studies conducted with other Gaviscon® formulations.. It is anticipated that 36

Data to be Analysed 
Definition of the analysis populations: 
• 
Full Analysis Set (FAS): All patients enrolled in the study; 
• 
Safety (Safety) population: All patients who are subjected to any invasive procedures 
and/or  take at least one dose of study medication;  
• 
Intention to treat (ITT) population: All patients who take at least one dose of study 
medication and have evaluable pH monitoring data for at least 1 hour post-dosing;  
• 
Per protocol (PP) population: The criteria for inclusion in the PP population will be 
confirmed during data checking, but will at least include the following: patients who 
adhered to the inclusive/exclusive criteria; did not take any prohibited medication 
which would interfere with evaluation of drugs in the study period; attended visits 
within the specified visit windows and had complete pH monitoring data for 4 hour 
post-dosing for both pH monitoring visits. 
The ITT population and safety population are the primary populations for evaluation of 
efficacy and safety, respectively. The PP population will be used for a secondary evaluation 
of the primary endpoint only. 
 
14.3 
Patient Disposition and Characteristics 
Descriptive summary statistics will be provided for demographic characteristics and baseline 
data for each treatment sequence group and all patients. For continuous parameters, mean, 
standard deviation, median, minimum, and maximum will be provided. For categorical 
parameters, the cell frequencies and percentage of patients in each category will be

Efficacy Analyses 
Results will be summarised by treatment for each dosing visit and overall (Compound 
Sodium Alginate Double Action Chewable Tablets, matching placebo tablets) using n, mean, 
standard deviation, median, minimum and maximum values. 
If less than 2 hours post-dosing monitoring data is available, for whatever reason, (or less 
than 1 hour post-dosing data within the first hour for parameters based on the first hour post-
dosing) the derived parameters will be considered missing.  If 2 or more hours post-dosing 
monitoring data is available, the parameters will be derived using the data available, and will 
be adjusted, where necessary, by multiplying by the factor (4 hours / time with data 
available).  Any data recorded more than 4 hours post-dosing will be ignored when deriving 
these parameters. 
 
14.4.1 
Primary Efficacy Analysis Endpoint 
The primary efficacy parameter will be the percentage of time during the 4 hour post dosing 
period with pH below pH 4. 
14.4.2 
Secondary Efficacy Endpoints 
The secondary endpoints will be: 
• 
Percentage of time during the 4 hour post dosing period with pH below pH 5 
• 
Number of occasions during the 4 hour post dosing period when pH falls below pH 4 
• 
Number of occasions during the 4 hour post dosing period when pH falls below pH 5 
• 
Number of reflux episodes during the 4 hour post dosing period with pH below pH 4 
for at least 5 minutes 
• 
Percentage of time during the first hour post dosing with pH below pH 4 
• 
Percentage of time during the first hour post dosing with pH below pH 5 
• 
Number of occasions during the first hour post dosing when pH falls below pH 4 
• 
Number of occasions during the first hour post dosing when pH falls below pH 5

14.4.3 
Statistical Methods for Efficacy Analyses 
SAS 9.1 (or later) will be used for statistical analysis. 
All statistical tests will be conducted using two-tailed tests at the 5% significance level. 
The null hypothesis at all times will be the equality of the fixed effect being compared from 
the model. 
The primary endpoint will be analysed primarily using an ANOVA of variance model with 
treatment, dosing visit treatment sequence as fixed effects and patient nested within 
treatment sequence as a random effect. The difference between treatment least square 
means will be used to represent the treatment differences. The effects for dosing visit and 
treatment sequence will also be assessed. A residual analysis will be performed. If there is a 
major departure from the assumptions of normality, independence or heteroscedasticity of 
residuals, then further analysis using transformed data will be used to support the original 
model results. If such assumptions still do not hold following an appropriate transformation 
then Wilcoxon Rank-Sum test will be used to compare the dosing visit difference (dosing 
visit 1 – dosing visit 2) between treatment sequence groups to represent the treatment 
comparison. 
All secondary endpoints will be analysed identically to the primary endpoint. 
All secondary endpoints and sensitivity or alternate analyses for the primary endpoint will 
serve as supportive evidence for the primary analysis only and therefore no adjustment for 
multiple comparisons will be made. 
14.5 
Safety Analyses 
Withdrawals will be listed in the Clinical Study Report (CSR) Appendices and summarised by 
reason for withdrawal.

Adverse events will be listed on a patient by patient basis in the CSR Appendices. The 
number of adverse events will be summarised by body system and preferred term, 
relationship to study medication and severity. The number of patients experiencing adverse 
events will also be summarised in the same manner. 
14.5.1 
Adverse Events 
All AEs will be coded using the most up-to-date version of MedDRA. For an individual 
patient, AEs that began prior to the first dose of IMP or more than one day after the final 
dose of IMP will not be included in the analysis.  
The incidence of AEs (number and percent of patients reporting each type of AE at least 
once during the study) will be summarised for all AEs, by investigator attribution of 
relationship to IMP and by severity. The incidence of AEs will be compared among 
(between) treatment groups using McNemar’s Test for all AEs, for those AEs classified by 
the Investigator as possibly, probably or certainly related to IMP and for severe AEs. 
 
14.5.2 
Laboratory Data 
For the purpose of analysing laboratory data, “baseline” is defined as the baseline 
assessments at Visit 1, screening and “last visit” is defined as the final visit, Visit 3 or the 
Early Termination Visit. 
Each pre-study baseline laboratory value will be categorised as low, normal, or high based 
on the reference range. Each post-baseline value will be classified in a similar manner, 
producing a 3 x 3 table for each treatment group at each post-baseline visit. Scores of “1” 
will be assigned to low values, “2” to normal values, and “3” to high values. Using these 
scores, shifts from baseline will also be assigned a score. For example, a laboratory value 
that shifts from low to high will be assigned a score of 2, whilst a laboratory value that 
remains at a low value will be assigned a score of 0. Shifts between these categories 
between baseline and subsequent timepoints will be compared using the Wilcoxon Signed-
Rank test within each treatment group. Statistical testing will be performed at last visit. 
At each visit, summary statistics for the absolute laboratory value and the changes from 
baseline will be presented by treatment group. The significance of changes from baseline 
will be assessed using the Wilcoxon Signed-Rank Test.  
Scatter plots of end of treatment values versus baseline values will be provided for all 
laboratory tests.

QUALITY CONTROL AND QUALITY ASSURANCE AUDIT 
15.1 
Monitoring 
The study will be monitored by site visits and meetings with the Investigator and co-
workers(s) at intervals agreed with the Investigator. The anticipated monitoring frequency will 
be stated in the Monitoring Plan. Monitoring will also involve, as appropriate, 
correspondence and telephone contacts. 
The Investigator, or a designated member of the Investigator’s staff, must be available at 
some time during the monitoring visit to review the data and resolve any queries and to allow 
direct access to the patient’s records for source data verification. 
At a site visit the CRFs forms should be made available in order that the accuracy of their 
completion may be checked. Each completed set of CRFs for each visit must be signed and 
dated by the Investigator, or a designated member of the Investigator’s medical staff, to 
verify the data and statements submitted. Similarly all alterations must be initialled and dated 
by the Investigator or a designated person, explained as necessary, with the original mistake 
left legible.

15.2 
Source Document Verification 
On-site monitoring will also include source document verification (SDV). SDV is the 
procedure whereby the data contained in the CRFs are compared with the primary source 
data (e.g. patient notes, original recordings from automated instruments, X-ray films, ECG 
tracings, laboratory results) contained in the patient records held at the investigational site, 
and thereby verified as accurate. 
The Investigator must be aware that: 
• 
SDV is a part of the normal monitoring process. It will be carried out by designated study 
personnel and will be done in such a way as to preserve patient confidentiality, taking 
into account all ethical and legislative requirements. 
• 
SDV will be carried out by direct comparison of entries made in the CRF with appropriate 
source data. Direct access to source data requires that the patient gives written, 
documented consent to this.  
• 
Where source data are in the form of a computer print-out (e.g. medical records, ECG 
tracings) they will be made available by the Investigator to the monitor. Each will be 
signed and dated by the Investigator or a designated person, confirming that the print-out 
is a true and faithful record of the data for that patient. These print-outs will be filed in the 
CRF. 
• 
The 
 Clinical Project Manager/Study Monitor will write an SDV Plan, specifying 
which data require SDV and what constitutes source data. This plan will also include the 
identification of any data to be recorded directly on the CRF and therefore considered 
source data. The Plan will be agreed with the Investigator and documented in the 
Initiation Visit Report.  For all patients, patient identity (date of birth, sex, initials and 
patient number), record of entry into the study and signature of informed must be verified 
from source documents as a minimum. In addition the following will be verified (add as 
appropriate): 
• 
pH monitoring data 
• 
Diagnosis of the condition under investigation and eligibility criteria 
• 
Laboratory reports  
• 
Details of adverse events 
• 
Concomitant medications

o Details of SAEs. 
 
It is important that the patient’s notes record important details about their participation in the 
study. The Investigator or designated person will agree, as a minimum requirement, to 
record the following information in the patient’s notes: 
• 
Study number, brief description or title of study. 
• 
Date that the patient gave written consent. 
• 
All visit dates. 
• 
All SAEs. 
• 
All concomitant medications. 
 
15.3 
Audit 
In accordance with the standards defined in ICH GCP, clinical studies sponsored by RB may 
be subject to an independent audit at the study site which will be conducted by personnel 
from an appropriate Quality Assurance Unit. Full consultation with the Investigator will be 
made prior to and during such audit, which will be conducted according to Quality Assurance 
Unit Standard Operating Procedures.

The approval letter must contain: 
• 
Name and address of the IEC/IRB. 
• 
Date of meeting. 
• 
Sufficient information to identify the version of both the protocol and patient 
information/informed consent. 
• 
Sufficient information to identify the version of other documents reviewed. 
The investigator must also provide RB with a list of IEC/IRB members that includes each 
member’s name, sex, and institutional affiliation. 
The Investigator must submit all protocol amendments to the IEC/IRB for approval and notify 
them of any administrative changes. 
 
16.2 
Patient Information and Consent 
Prior to entering the study, the Investigator or designated assistant will explain to each 
patient or legally acceptable representative, the nature of the study, its purpose, procedures, 
expected duration, alternative therapy available, and the benefits and risks involved in study 
participation. Patients will be given information and consent documents and the opportunity 
to ask questions. They will be informed of their right to withdraw from the study at any time 
without prejudice. After this explanation and before any study-specific procedures have been 
performed, the patient, or legally acceptable representative, will voluntarily sign and date the 
informed consent form. The person conducting the informed consent discussion and 
providing the information to the patient will also sign and date the consent form. Prior to 
participation in the study, the patient will receive copies of the written information and their 
signed and dated consent document, plus any other written information provided to them.

REGULATORY REQUIREMENTS 
17.1 
Competent Authority Authorisation 
This study proposal was submitted to the SFDA and approved on 4 June 2010.   The 
approval number is 2010L02452. 
 
17.2 
Curriculum Vitae 
A current curriculum vitae (CV) will be obtained from all personnel with significant study 
responsibilities, i.e. the Investigator and those to whom he or she has delegated some of 
his/her responsibilities as well as those whose names appear on the signature and 
delegation of duties forms (see below).  
The CV will contain as a minimum the following information: name, current work address, 
qualifications, current position and previous positions. It will be signed and dated within 2 
years of the start of the study. The CVs will be maintained on file by RB. 
The Investigator and individuals to whom the Investigator has delegated some of his or her 
responsibilities as an investigator will be asked to provide sample signatures. The duties 
delegated to them will also be recorded on the signature and delegation of duties forms. 
 
18 
DATA HANDLING AND RECORD KEEPING 
18.1 
Case Report Forms (CRFs) 
Electronic CRFs (eCRFs) will not be used in this study. The Investigator is responsible for 
the quality of the data recorded in the CRF. The data recorded should be a complete and 
accurate account of the patient’s record collected during the study. The Investigator and 
study monitor will identify any data that will be recorded directly on the CRF such that the 
CRF will be considered the source document (i.e. no prior written or electronic record of the 
data). The study monitor will document this on the Initiation Visit Report. 
The Investigator and other staff who have been delegated responsibility for entering data 
into the CRF at each visit will be trained in the use of the paper/No carbon required (NCR) 
CRFs before the first patient at that site is enrolled. The Investigator must review all entries 
for completeness and correctness. When changes or corrections are made on any 
paper/NCR CRF, the Investigator or authorised persons must draw a single line through the 
error then initial and date the correction, as well as stating the reason for the error, except

when due to a transcription error. The original entry should not be obscured. Data 
management will be conducted by Quintiles. The paper CRF / NCR CRF system will keep an 
audit trail of all changes made after the CRF pages are initially completed and submitted. 
The Investigator agrees to complete and sign the CRFs in a timely fashion after completion 
of each patient and make them available to the study monitor for full inspection. In addition, 
any data queries prepared after the original CRF has been completed should be answered 
promptly. Following monitoring of each patient’s paper CRF / NCR CRF, the investigator will 
sign the CRF. Re-signature by the Investigator may be required prior to database lock after 
resolution of interim data queries. 
Before acceptance, the study monitor will review the CRFs for completeness and adherence 
to the protocol. If a paper CRF is being used, the top copy will be submitted to the 
organisation responsible for data management and a second copy will be retained by the 
Investigator in the Study Site File.  
 
18.2 
Retention of Essential Documentation 
The Investigator should retain all essential documents (as defined in ICH E6 or according to 
other national and international regulations) until at least 5 years after the completion of the 
study. These documents should be retained for a longer period, however, if required by the 
applicable regulatory requirements or by an agreement with RB. It is the responsibility of RB 
to inform the Investigator when these documents no longer need to be retained. 
Patient files and other source data must be kept for the maximum period of time permitted by 
the hospital, institution or private practice. The Investigator must notify RB if his/her 
institution’s policy is to retain documents for a shorter period of time. 
 
18.3 
Protocol Amendments 
The investigator must abide by the agreed protocol as approved by the IEC/IRB. 
No change will be made to the agreed protocol without the prior written approval of the 
Investigator, the Clinical Project Manager, the R&D Manager Clinical (Healthcare) and the 
Global Medical Director, except in circumstances where the immediate safety of the patient 
is at risk. Written approval will also be obtained from other functions if appropriate, for 
example the Statistician if the amendment relates to a change in endpoints.

CLINICAL TRIAL AGREEMENT 
Before the study commences, a Clinical Trial Agreement be will signed in which financial 
aspects of the study (including financial disclosure) as well as responsibilities and obligations 
are described. This will take the form of: 
• 
A contract between 
 and the Investigator/healthcare organisation. 
 
20 
COMPENSATION, INDEMNITY AND INSURANCE 
20.1 
Compensation 
Appropriate treatment and/or compensation will only be provided and/or paid to the patient 
by the Sponsor to the extent that a patient suffers injury or death directly attributable to 
participation in the study without: 
• 
Fault on the part of the investigator or the CRO or its employees or agents. 
• 
The investigator or the CRO failing to comply with the protocol. 
• 
The investigator or the CRO failing to notify the Sponsor of the claim or denying the 
Sponsor full conduct of the claim.  
In any event, such compensation and treatment shall only be provided by the Sponsor to the 
extent required by the applicable law. 
 
20.2 
Indemnity 
RB will provide appropriate indemnity for the Investigator and staff who conduct part or all of 
this study, upon request. The request must be received before the first patient is recruited.

Insurance 
If required, and in accordance with applicable regulatory and legal requirements, RB will take 
out appropriate insurance policies on behalf of the Investigator and staff who conduct part or 
all of this study, and/or on behalf of the patients participating in the study. 
 
21 
REPORTING, PUBLICATION AND PRESENTATION 
A clinical study report will be prepared according to ICH E3 (Structure and Content of 
Clinical Study Reports) as part of RB’s commitment to Good Clinical Practice. The report will 
be a record of the total study conduct and findings, and will be subject to approval by the Co-
ordinating Investigator who will sign the final report. 
The study data will be owned by RB. RB retains the right to publish the data independently 
of the Investigator. RB agrees that before it publishes the results, it will provide the 
Investigator with at least 30 days for full review prior to submission of the manuscript to the 
publisher. The Investigator must submit any proposed manuscript to RB for approval prior to 
submission for publication. 
Any publication must state that it is a part of a multicentre study. Where it would be 
impractical to send the manuscript to every Investigator in a multicentre study, a copy will be 
sent to the Co-ordinating Investigator. In such a study, RB may wish to publish the results of 
the study and this may be done without all participants having the opportunity to review the 
manuscript.
