chemistry, urinalysis, haematology, viral serology, blood pregnancy test for 
females, urinary drug screen, measurement of height and weight (includes 
calculation of BMI), coagulation, serum FSH if applicable, vital signs 
measurement, body temperature, alcohol breath test, urinary cotinine test. 
Total 
Blood 
Volume Taken 
+ 11.5 mL for screening 
+ 21 (samples) x 2 (study periods) x 2 mL = 84 mL 
+ 20 (catheter purge) x 2 (study periods) x 2 mL = 80 mL 
+ 11.5 mL at end of study visit  
= 187 mL of blood in total 
About 20 mL of blood can be additionally withdrawn if repeated laboratory 
tests will be required during screening or follow-up. If one or more blood 
collections must be repeated during the study, it may be necessary to withdraw 
additional amount of blood. The reason for such additional blood collections 
must be justified by Investigator. 
Vital Signs (Blood 
pressure, heart rate, 
respiratory rate) 
 
Body temperature 
Vital signs will be monitored during screening procedures, check-in, prior to 
dosing (-1.00) and at 2.00, 4.00, 12 and 24 hours after IMP administration in 
each Study Period, every day during the subjects’ stay in clinical unit (including 
at -12:00 hour before second dose) and at exit examination.  
Body temperature will be measured during screening, check-in, twice a day 
during the subjects’ stay in clinical unit, and at exit examination. 
Query on AE 
Query on AE will be performed during check-in and every day during 
hospitalization.

Study Design: 
This will be a 2-arm, single center, single dose, open-label, randomized, two-sequence, two-
period crossover, bioequivalence study in healthy adult subjects. 
Subjects will be screened for eligibility within 15 days prior to dosing. Subjects will receive 
each of the two study treatments in fasted state during a 6-day (5-overnight stay) residential 
period at the study site. Subjects will receive each treatment in a randomized order with a 
washout period of at least 72-hour between doses. During each treatment period, subjects will 
provide a pre-dose blood sample 1 hour before dosing and 20 post-dose blood samples at 5, 10, 
20, 30, 40, 50, 60, 80, 90, 120, 150, 180 minutes, 4, 5, 6, 8, 10, 12, 14, 16 hours, for bioanalytical 
analyses of paracetamol.

Type and Planned Number of Subjects: 
Approximately 110 subjects will be screened to randomize approximately 37 healthy adult 
subjects to ensure at least 31 evaluable subjects complete the entire study. In addition, two (2) 
overnight stand-by subjects will be confined until the first dosing as a reserve for pre-dose 
dropouts. 
Statistical Methods: 
The bioequivalence between a new paracetamol oral suspension (Test) and the marketed 
paracetamol oral suspension (Panadol B&I) (Reference) in fasted state will be assessed on the 
PK population:

• If the 90% confidence intervals (CIs) for the ratio of the means of the primary 
pharmacokinetic parameters, AUC0-tlast and Cmax of the paracetamol profiles lie 
completely within the range 0.8-1.25.  
• If there is no difference between the two treatments in terms of tmax.  
An Analysis of Variance (ANOVA) model will be fitted to the log-transformed PK variables 
(AUC0- tlast and Cmax), as the dependent variable, and treatment, period, sequence and subject 
nested within sequence as fixed effects. For each pairwise comparison, only the data from the 
two corresponding treatments will be included in the model. The presence of a statistically 
significant sequence effect will be noted, and its implications will be discussed. Least squares 
estimate of treatment effects will be calculated and a 90% confidence interval (CI) for the 
treatment difference will be computed. The treatment difference and its CI will be exponentiated 
to obtain the ratio of the geometric least square means between the test and reference and its CI. 
Bioequivalence will be determined if the 90% CI for the treatment geometric least square mean 
ratio lies completely within the range 0.80 – 1.25.  
tmax will be analyzed nonparametrically using Wilcoxon signed-rank test. Median of differences 
between treatments will be presented with 90% CI for the median difference based on a method 
by Hodges and Lehman based on PK population. 
AUC0-inf will be analyzed using the same ANOVA model method as for AUC0-tlast and Cmax. 
%AUCex and λz will be summarized for each treatment using descriptive statistics same as for 
the primary PK parameters.

2 There will be a 72-hour washout scheduled between each dose administered 
3 These assessments are also to be conducted for subjects who discontinue study drug. These assessments will 
occur before discharge, on study Day 5 
4 Vital Signs- includes systolic and diastolic blood pressures, heart rate and respiratory rate measurement. Pre-
treatment measurements (i.e. day 1 and day 4) of vitals will happen 1 hour before the scheduled drug administration 
with allowance up to +50 minutes from the scheduled time but must be measured before intravenous catheter 
insertion. Post treatment measurement will take place at 2.00, 4.00 and 12.00 and 24.00 hours after dosing. 
Additional measurements will be performed for medical reasons if necessary. 
5 Based on the actual epidemiologic situation, body temperature will be measured in all subjects in the morning 
and in the evening during the stay at the clinical unit. 
6 For detection of COVID-19, test/s are to be performed as follows: 
• 
At screening visit- RT PCR test is to be done. 
• 
At check-in and early discontinuation or end of study- Antigen test is to be done. 
• 
At any time during residential period in study, when subjects report symptoms suggestive of COVID-19, 
subject will be isolated and antigen test is to be done. If test result is negative, isolate the subject in unit and 
conduct RT PCR. If test result is positive, conduct RT PCR test and discharge the subject for further 
management. Further details in Section 9.3.8: COVID-19 test.

dissolution study has been performed to confirm that both products show similar in vitro release 
characteristics. 
Paracetamol can be considered as highly permeable drug. Like BCS class I drugs, their 
bioavailability is unlikely to be affected by any change of small intestine transit time caused by 
sorbitol/ maltitol or any other critical excipients  
2.3 
Benefit/Risk Assessment  
Complete information for this paracetamol oral suspension may be found in the single reference 
safety document (SRSD), which for this study is the Summary of Products Characteristics 
(SmPC) for Czech Republic. 
2.4 
Mechanism of Action/Indication 
Paracetamol is an analgesic and antipyretic without anti-inflammatory effect and with good 
gastrointestinal tolerability. It is suitable for adults and in pediatrics. The mechanism of action 
is likely to be similar to that of acetylsalicylic acid and is dependent on the inhibition of 
prostaglandins primarily in the central nervous system.

STUDY OBJECTIVES AND ENDPOINTS 
Table 3-1 
Study Objectives and Endpoints 
Objective(s) 
Endpoint(s) 
Primary  
• 
To demonstrate the bioequivalence of 
paracetamol in a new paracetamol oral 
suspension 
versus 
the 
marketed 
paracetamol oral suspension (Panadol 
B&I)  
• AUC0-tlast (The area under the plasma 
concentration versus time curve 
calculated from time 0 to the last 
measurable sampling time point, t, 
computed using the linear trapezoidal 
rule)  
• tmax (The time of the maximum 
observed post-dose concentration) 
• Cmax (The maximum observed post-
dose concentration) 
Secondary 
• Assess the pharmacokinetic profile of 
new and the marketed paracetamol oral 
suspension  
• AUC0-inf (The area under the plasma 
concentration versus time curve 
calculated from time 0 to infinity 
AUC0-inf = AUC0-t + C(t)/λz where 
C(t) is the concentration at the last 
measurable sampling time point and 
λz is the terminal elimination rate 
constant) 
• %AUCex (Percentage of AUC0-inf 
obtained by extrapolation, calculated 
as (1－ [AUC0-t /AUC0-inf]) ×100)

• λz (The terminal elimination rate 
constant computed as the slope of the 
regression line of ln (C(t)) on time. 
The regression should generally 
involve at least 3 consecutive 
measurable 
concentrations 
that 
decrease over time) 
Safety 
Assess the safety profile of both products  
• AEs, vital signs and clinical safety 
laboratory test results 
This study will be considered successful if bioequivalence between the new and the currently 
marketed paracetamol oral suspension concludes that the 90% CIs for the ratio of the means of 
the primary pharmacokinetic parameters AUC0-tlast and Cmax of the paracetamol profiles lie 
completely within the range 0.8-1.25, and if there is no difference between the two treatments 
in terms of tmax.

STUDY DESIGN  
4.1 
Overall Design 
This will be a 2-arm, single center, single dose, open-label, randomized, two-sequence, two-
period crossover, bioequivalence study in healthy adult subjects. Subjects will be screened for 
eligibility within 15 days prior to dosing. Subjects will receive each of the two study treatments 
in fasted state during a 6-day (5-overnight stay) residential period at the study site. Subjects will 
receive both treatment regimens in a randomized order with a 72-hour washout period between 
each dose. During each treatment period, subjects will provide a pre-dose blood sample 1 hour 
before dosing and 20 post-dose blood samples at 5, 10, 20, 30, 40, 50, 60, 80, 90, 120, 150, 180 
minutes, 4, 5, 6, 8, 10, 12, 14, 16 hours, for bioanalytical analyses of paracetamol. The schedule 
of activities table (Table 4-1) provides an overview of the subject visits and study procedures. 
Table 4-2 provides an overview of the PK sampling scheme during the study.

3 These assessments are also to be conducted for subjects who discontinue study drug. These assessments will occur before 
discharge, on study Day 5 
4 Vital Signs- includes systolic and diastolic blood pressures, heart rate and respiratory rate measurement. Pre-treatment 
measurements (i.e. day 1 and day 4) of vitals will happen 1 hour before the scheduled drug administration with allowance up 
to +50 minutes from the scheduled time but must be measured before intravenous catheter insertion. Post treatment 
measurement will take place at 2.00, 4.00 and 12.00 and 24.00 hours after dosing. Additional measurements will be performed 
for medical reasons if necessary. 
5 Based on the actual epidemiologic situation, body temperature will be measured in all subjects in the morning and in the 
evening during the stay at the clinical unit. 
6 For detection of COVID-19, test/s are to be performed as follows: 
• 
At screening visit- RT PCR test is to be done. 
• 
At check-in and early discontinuation or end of study- Antigen test is to be done. 
• 
At any time during residential period in study, when subjects report symptoms suggestive of COVID-19, subject will be 
isolated and antigen test is to be done. If test result is negative, isolate the subject in unit and conduct RT PCR. If test 
result is positive, conduct RT PCR test and discharge the subject for further management. Further details in Section 9.3.8: 
COVID-19 test.

during the study, a decision for the subject’s continuation will be made by the investigator, 
based on the time the medication was administered and, on the pharmacology, and 
pharmacokinetics of the study drug and the concomitant medication. 
4.4 
End of Study Definition 
A subject is considered to have completed the study if he or she has completed all phases of the 
study including the last visit or the last scheduled procedure shown in the Schedule of Activities. 
The end of this study is defined as the date of the last visit of the last subject in the study.

STUDY POPULATION 
5.1 
Type and Planned Number of Subjects 
Since the collection of detailed biopharmaceutic data in vulnerable children is difficult due to 
ethical considerations, this study plans to collect adult data with the assumption that the adult 
observations can be extrapolated to children. For the study healthy adult subjects aged 18-45 
years will be selected. 
Approximately 110 subjects will be screened to randomize approximately 37 healthy adult 
subjects to ensure at least 31 evaluable subjects complete the entire study. An enrolled subject 
will be the one who has agreed to participate in the clinical study following completion of the 
informed consent process and successfully met eligibility criteria to proceed beyond the 
screening visit as applicable for the protocol design.  
This study can fulfill its objectives only if appropriate subjects are enrolled.  The following 
eligibility criteria are designed to select subjects for whom participation in the study is 
considered appropriate.  All relevant medical and non-medical conditions should be taken into 
consideration when deciding whether a subject is suitable for this protocol.   
Subject eligibility to participate in the clinical study should be reviewed and documented by an 
appropriate member of the investigator’s study team before subjects are included in the study. 
5.2 
Inclusion Criteria 
An individual must meet all the following inclusion criteria to be eligible to be included into 
the study: 
1. Subject provision of a signed and dated informed consent document indicating that the 
subject has been informed of all pertinent aspects of the study before any assessment is 
performed. 
2. Subject is male or female 
3. Subject is 18 to 45 years of age inclusive, at the signing of the informed consent. 
4. A subject who is willing and able to comply with scheduled visits, treatment plan, laboratory 
tests, study restrictions and other study procedures. 
5. A subject in good general and mental health with, in the opinion of the investigator or 
medically qualified designee, as determined by medical evaluation, including medical 
history, full physical examination, including blood pressure and pulse rate measurement, 
12-lead ECG or clinical laboratory tests

Study products will be administered under the supervision of investigator site personnel. The 
designated dosing personnel must check the mouth to ensure that the suspension has been 
swallowed. A record of the administration of study treatments (time and date of preparation of 
study drug, study drug ingestion start and stop time and date, including dates for intervention 
delays) will be kept using the Dosing Accountability Log and the CRF, any comments on the 
performance of this procedure should be recorded on the CRF. Any violation of compliance 
will require evaluation by the investigator and sponsor to determine if the subject will continue 
in the study. 
6.8

Should the subject continue to be unreachable, he/she will be considered to have withdrawn 
from the study and lost to follow up.  
Lack of completion of all or any of the early termination procedures will not be viewed as 
protocol deviations so long as the subject’s safety was preserved. 
If the subject withdraws from the study and withdraws consent for disclosure of future 
information, no further evaluations should be performed, and no additional data should be 
collected.  The sponsor may retain and continue to use any data collected before such 
withdrawal of consent.

STUDY PROCEDURES 
This section lists the procedures to be completed at each planned study visit.  An overview of 
study activities is provided in Table 4-1 and Table 4-2. 
Adherence to the study design requirements, including all procedures are essential and required 
for study conduct.  
The site may contact subjects prior to study visit as part of pre-screening activities and follow 
up of AEs as detailed in Section 8.4: Follow up Visits Further details will be included in the 
Informed Consent Form (ICF). Subjects will be invited for antigen test at least 16 hours before 
check-in. Subjects will be then confined from at least 12 hours before dosing until after the 
second 24-hour post-dose blood collection. There will be a washout of at least 72 hours between 
drug administration.  
Participation of each subject in this study should last approximately 1 month (from the time of 
ICF signature to the end of the clinical part of the study). 
8.1 
Screening 
Screening procedures will be conducted by the Investigator, or suitably qualified designee. 
Subjects will be screened within 15 days prior to administration of the investigational product 
to confirm that they meet the subject selection criteria for the study.   
The following procedures will be completed: 
8.1.1 
Informed Consent 
The investigator, or designee, must obtain informed consent from each subject participating in 
this study after adequate explanation of the aims, methods, objectives, and potential hazards of 
the study. Two copies of the ICF will be signed and dated by the subject, the subject will retain 
one copy and the other will be kept at site. 
The investigator, or designee, must also explain to the subjects that they are completely free to 
refuse to enter the study or to withdraw from it at any time.  Appropriate forms for documenting 
a signed and dated consent will be provided by either the investigator or by GSKCH. 
The investigator, or designee, should sign and date each copy of the ICF to confirm that the 
consent process was completed correctly after the subject has signed.   
The time the subject signed the informed consent form will be captured as this is the point at 
which all Adverse Events will be captured from. The date and time of consent will be captured 
in the CRF.

recorded on the Study Conclusion page. 
If a subject has any clinically significant, study-related abnormalities or AEs at the end of the 
study, the GSKCH medical monitor (or designated representative) should be notified and, the 
subject may be asked to remain at the clinical site or be asked to return for a follow-up visit to 
ensure any issue is resolved or deemed not clinically significant.  
8.4 
Follow-up Visit 
The study site may contact a subject to follow up an AE post-study completion/withdrawal and, 
in some circumstances, request they return to the site for additional follow-up visits (final safety 
assessments). If needed, additional examinations may be carried out at such visits.

STUDY ASSESSMENTS 
Every effort should be made to ensure that protocol-required tests and procedures are completed 
as described.  However, it is anticipated that from time to time there may be circumstances, 
outside the control of the investigator that may make it unfeasible to complete an assessment.

9.3.5 
Blood Pressure and Pulse Rate  
Additional collection times, or changes to collection times of blood pressure and pulse rate will 
be permitted, as necessary at the discretion of the investigator, to ensure appropriate collection 
of safety data. 
Supine blood pressure will be measured with the subject’s arm supported at the level of the 
heart and recorded to the nearest mm Hg after a minimum 5 minutes of rest.  The same arm 
(preferably the dominant arm) will be used throughout the study.  The same properly sized and 
calibrated blood pressure cuff will be used to measure blood pressure each time. The use of an 
automated device for measuring BP and pulse rate is acceptable, although, when done manually, 
pulse rate will be measured in the brachial/radial artery for at least 30 seconds.   In case of 
coincidence of one or more clinical procedures, and unless deemed by the Investigator 
necessary otherwise, the order of procedures is: Blood Sampling > Vital Signs Reading > AE 
Checks > water intake and/or food intake. 
Systolic and diastolic blood pressures (BP, mmHg) and heart rate (HR, bpm) will be monitored 
during screening procedure, check in, prior to dosing (-1.00) and 2.00, 4.00 and 12.00 and 24.00 
hours after dosing, every day during the subjects’ stay in clinical unit and at exit examination. 
Additional measurements will be performed for medical reasons if necessary. 
Pre-dose vital signs (-1.00 hour) will be measured with allowance up to +50 minutes from the 
scheduled time but must be measured before intravenous catheter insertion. After the drug 
administration, the vital signs will be measured after blood samples drawing with allowance up 
to +15 minutes from the scheduled time. 
The Investigator should be notified immediately, if BP (systolic/diastolic) is outside the range 
of 90-140/60-90 mmHg or HR out of range 50-100 bpm during check-in on day -1, prior to 
dosing (-1.00 hour) and 2.00, 4.00, 12.00 and 24.00 hours after dosing in each period. The 
Investigator should assess clinical significance of each deviation from above described range 
of BP or HR. 
9.3.6 
Respiratory Rate 
Respiratory rate will be measured as a part of vital signs, along with blood pressure and heart 
rate assessment. It will be measured after approximately 5 minutes rest in supine position by 
observing and counting the respirations of the subject for 30 seconds and multiplied by 2.  When 
blood pressure is to be taken at the same time, respiration measurement will be done during the 
5 minutes of rest and before blood pressure measurement. 
9.3.7 
Body Temperature 
Body temperature will be measured during screening procedures, check in, in the morning and 
in the evening during the subjects’ stay at the clinical unit, and at exit examination and 
additionally based on Investigator’s judgement. 
Abnormal values ranges are < 35.4 and/or ≥ 37.3°C. 
9.3.8 
COVID-19 Test 
Nasopharyngeal swab will be collected to test for COVID-19 using RT PCR or antigen test, at 
times specified in the Section 8: Study procedures. Two consecutive negative tests for active 
COVID-19 separated by > 24 hours are required for inclusion in the study. The second test will 
be done on the day of check-in (Day -1).

 Pharmacokinetics (PK) 
9.5.1 
Plasma for Analysis of Paracetamol 
In morning of dosing days of both study periods a dead-volume intravenous catheter will be 
inserted into a forearm vein (starting at 06:00 o’clock) by skilled nurses under Investigator’s 
supervision. Catheter insertion is not applicable for stand-by subjects if not necessary. Blood 
samples will be obtained by the catheter for the first 16 hours post-dose. The blood samples 
may be collected by direct venipuncture in case that subject refuses the insertion of the catheter 
or if the catheter is blocked and/or needs replacement. 
During all study periods, blood samples (2mL in each sampling) for pharmacokinetic analysis 
will be collected into appropriately labeled tubes at times specified in the Section 8: Study 
Procedures. 
Total number of blood collections in each study period will be 21. Blood samples will be taken 
at Pre-dose (1 hour before dosing) , and 5, 10, 20, 30, 40, 50, 60, 80, 90, 120, 150, 180 minutes, 
4, 5, 6, 8, 10, 12, 14, 16 hours post-doses.  
Actual times of PK-blood sampling will be recorded immediately after each blood sampling. 
The actual sample times may change but the number of samples will remain the same.  All 
efforts will be made to obtain the pharmacokinetic samples at the exact nominal time relative 
to dosing.  Sampling time deviations ≥ 2 minutes will be repotted during the first 6 hours after 
drug administration. Sampling time deviations ≥  15 minutes will be reported for all remaining 
sampling intervals. During each sampling, venous blood samples (2 ml) will be withdrawn by 
a suitable trained member of the study staff, either from an indwelling cannula or venipuncture

ADVERSE EVENT AND SERIOUS ADVERSE EVENTS 
The investigator and any qualified designees are responsible for detecting, documenting, and 
reporting events that meet the definition of an AE or SAE and remain responsible for following 
up AEs that are serious, considered related to the study product or the study, or that caused the 
subject to discontinue the study product or study 
10.1 
Definition of an Adverse Event (AE) 
An AE is any untoward medical occurrence in a clinical study subject, temporally associated 
with the use of a study product including any washout product, whether or not considered 
related to the study product, including any washout product. 
NOTE: An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the 
use of a study product 
Events Meeting the AE Definition:   
• Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (e.g. ECG, radiological scans, vital sign measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (i.e., not related to normal/ expected 
progression of underlying disease). 
• Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition. 
• New conditions detected or diagnosed after study product administration even though 
it may have been present before the start of the study. 
• Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
• Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
product or a concomitant medication. Overdose per se will not be reported as an 
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-harming 
intent. Such overdoses should be reported regardless of sequelae. 
Events NOT meeting the AE definition:  
• Any clinically significant abnormal laboratory findings (if applicable) or other abnormal 
safety assessments which are associated with the underlying disease, unless judged by 
the investigator to be more severe than expected for the subject’s condition.  
• The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the subject’s 
condition.

Page 65 of 85 
• Medical or surgical procedure (e.g. endoscopy, appendectomy) is not the AE. The 
condition that leads to the procedure is an AE (e.g. appendicitis). 
• Situations where an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
• Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen.  
10.2 
Definition of a Serious Adverse Event (SAE) 
A Serious Adverse Event (SAE) is a particular category of an adverse event where the adverse 
outcome is serious. If an event is not an AE per definition above, then it cannot be an SAE even 
if serious conditions are met (e.g. hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease). 
A serious adverse event is any untoward medical occurrence at any dose that: 
• Results in death 
• Is life-threatening  
▪ The term 'life-threatening' in the definition of 'serious' refers to an event in which 
the subject was at risk of death at the time of the event. It does not refer to an event, 
which hypothetically might have caused death, if it were more severe; 
• Requires inpatient hospitalization or prolongation of existing hospitalization  
▪ In general, hospitalization signifies that the subject has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the 
physician’s office or outpatient setting. Complications that occur during 
hospitalization are AEs. If a complication prolongs hospitalization or fulfills any 
other serious criteria, the event is serious. When in doubt as to whether 
“hospitalization” occurred, or was necessary, the AE should be considered serious. 
▪ Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE. 
• Results in persistent or significant disability/incapacity 
▪ The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
▪ This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (e.g. sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption 
• Results in congenital anomaly/birth defect 
• Other situations: 
▪ Medical or scientific judgment should be exercised in deciding whether SAE 
reporting is appropriate in other situations such as important medical events that 
may not be immediately life-threatening or result in death or hospitalization but 
may jeopardize the subject or may require medical or surgical intervention to 
prevent one of the other outcomes listed in the above definition. These events 
should usually be considered serious. 
▪ Examples of such events include invasive or malignant cancers, intensive treatment 
in an emergency room or at home for allergic bronchospasm, blood dyscrasias or

convulsions that do not result in hospitalization, or development of drug 
dependency or drug abuse. 
Note: Classification of an AE as ‘serious’ is based on the outcome of the event and is a factor 
in determining reporting requirements. 
10.3 
Time Period and Frequency for Collecting AE and SAE 
Information 
The Adverse event reporting period begins when the subject first signs informed consent and 
continues until 7 days following last administration of the study product (or last procedure. All 
AEs should be recorded in the CRF in a timely manner. Serious AEs MUST be recorded and 
reported to the Sponsor or designee in the eSAE CRF page immediately (within a maximum of 
24 hours). The investigator will submit any updated SAE data to GSK within 24 hours of it 
being informed. 
Medical occurrences that began before obtaining informed consent will be recorded in the 
Medical History/Current Medical Conditions section of the CRF not the AE section. 
Details recorded by the subject on a diary or similar document that meet the definition of an AE 
must also be discussed with the subjects and transcribed in the AE section of the CRF.  
All SAEs will be recorded and reported to the sponsor or designee immediately and under no 
circumstance should this exceed 24 hours. The investigator will submit any updated SAE data 
to the sponsor within 24 hours of it being available. 
Investigators are not obligated to actively seek AEs or SAEs after the conclusion of the study 
participation. However, if the investigator learns of any SAE, including a death, at any time 
after a subject has been discharged from the study, and he/she considers the event to be 
reasonably related to the study product or study participation, the investigator must promptly 
notify the sponsor. 
10.4 
Reporting Procedures 
The investigator and any designees are responsible for detecting, documenting and reporting 
events that meet the definition of an AE and remain responsible for following up on AEs that 
are serious, considered related to the study product(s), participation in the study, or a study 
procedure, or that caused the subject to discontinue the study product or study.  
Spontaneous reporting of adverse events and those elicited by asking subjects to respond to 
non-leading such as “How do you feel” will be assessed and any AE’s recorded in the CRF and 
reported appropriately. 
The investigator (or medically qualified designee) is to report all directly observed AEs and all 
AEs spontaneously reported by the study subject. In addition, each study subject will be 
questioned about AEs.  
Each AE is to be assessed to determine if it meets the criteria for a SAE.  If an SAE occurs, 
expedited reporting will follow local and international regulations, as appropriate. 
When an AE occurs, it is the responsibility of the investigator (or medically qualified designee) 
to review all documentation (e.g. hospital progress notes, laboratory, and diagnostics reports) 
related to the event. 
The investigator or site staff will then record all relevant information regarding an AE in the 
CRF and all details relating to an SAE in the eSAE Form.

It is not acceptable for the investigator (or medically qualified designee) to send photocopies 
of the subject’s medical records to GSKCH in lieu of completion of the AE CRF page/eSAE 
form. 
There may be instances when copies of medical records for certain cases are requested by 
GSKCH.  In this instance, all subject identifiers, except for the subject number, will be redacted 
on the copies of the medical records prior to submission to GSKCH. 
The investigator (or medically qualified designee) will attempt to establish a diagnosis of the 
event based on signs, symptoms, and/or other clinical information.  The diagnosis will be then 
documented as the AE/SAE where known and not the individual signs/symptoms. (e.g. upper 
respiratory tract infection, seasonal allergy, etc. instead of runny nose). 
AEs elicited by the investigator (or medically qualified designee) in a standard manner at the 
study visits should also be recorded in the AE section of the CRF and/or using the eSAE form 
(subject to the classification of the AE). Care will be taken not to introduce bias when 
questioning a subject about any changes in their health. Open-ended and non-leading verbal 
questioning should be used. 
10.4.1 
Reporting of an Adverse Event 
All AEs will be reported on the AE page of the CRF by the investigator or site staff.  It should 
be noted that the form for collection of SAE information is not the same as the AE CRF.  Where 
the same data are collected, the AE CRF page and the SAE form must be completed in a 
consistent manner.  For example, the same AE term should be used on both.  AEs should be 
reported using concise medical terminology on the CRF as well as on the electronic form for 
collection of SAE information. 
10.4.2 
Reporting of a Serious Adverse Event 
In addition to recording the details of each AE on the AE CRF page, an eSAE form should be 
completed, as fully as possible.  
It is essential to enter the following information:  
• Protocol and subject identifiers 
• Subject demography 
• Description of events, with diagnosis if available 
• Investigator opinion of relationship to study product (or study procedure, if appropriate) 
• Criterion for seriousness. 
The following are desirable and are of particular relevance for investigator and GSKCH 
assessment of the eSAE report: 
• Date of onset of AE  
• Date AE stopped, if relevant 
• Study product start date 
• Study product end date if relevant 
• Action taken in relation to the study product 
• Outcome if known

H1: The (geometric) mean AUC0- tlast (likewise Cmax) of a new paracetamol oral suspension 
(Test) is between 80.0% and 125.0% of that of Panadol B&I (Reference). 
tmax 
H0: There is no difference between a new paracetamol oral suspension (Test) and Panadol B&I 
(Reference). 
H1: There is a difference between a new paracetamol oral suspension (Test) and Panadol B&I 
(Reference). 
An Analysis of Variance (ANOVA) model will be fit to the log-transformed PK parameters 
(AUC0- tlast and Cmax), as the dependent variable, and treatment, period, sequence and subject 
nested within sequence as fixed effects. For each pairwise comparison, only the data from the 
two, corresponding treatments will be included in the model. The presence of a statistically 
significant sequence effect will be noted, and its implications will be discussed. Least squares 
estimates of treatment effects will be calculated and a 90% CI for the treatment difference will 
be computed. The treatment difference and its CI will be exponentiated to obtain the ratio of 
the geometric least square means between the test and reference and its CI. Bioequivalence will 
be determined if the 90% CI for the treatment geometric least square mean ratio lies completely 
within the range 0.80 – 1.25.  
tmax will be analyzed nonparametrically using Wilcoxon signed-rank test. Median of differences 
between treatments will be presented with 90% CI for the median difference based on a method 
by Hodges and Lehman based on the PK population. 
Individual plasma concentrations of paracetamol will be summarized descriptively by treatment 
and each time point for the PK population and will be listed for the safety population.  Mean 
plasma concentration vs. nominal time profiles by treatment will be graphed for the PK 
population. Individual plasma concentration vs. actual time profiles by treatment and individual 
plasma concentrations vs. actual time profiles by subject will be graphed for the safety 
population. All concentration-time profiles will be shown on both original and semi-logarithmic 
scales. 
All PK parameters will be summarized for each treatment by descriptive statistics (for tmax 
and %AUCex, N, arithmetic mean, standard deviation, first and third quartiles, median, 
minimum, and maximum; for the rest of PK parameters, N, arithmetic mean, standard deviation, 
geometric mean, coefficient of variation of geometric mean, median, minimum, and maximum) 
for the PK population.  
A listing containing individual statistics for each PK parameter will be provided for the safety 
population.  
12.3.2 
Secondary Analysis(es) 
The secondary pharmacokinetics Analysis Variables: 
• AUC0-inf-area under the plasma concentration time curve from zero and extrapolated to infinity 
time. 
• %AUCex-Percentage of AUC0-inf  obtained by extrapolation, calculated as (1－ [AUC0-t /AUC0-
inf]) ×100) 
• λz -The terminal elimination rate constant computed as the slope of the regression line of ln 
(C(t)) on time. The regression should generally involve at least 3 consecutive measurable 
concentrations that decrease over time.

AUC0-inf will be analyzed using the same ANOVA model method as for AUC0-tlast and Cmax. 
%AUCex and λz will be summarized for each treatment using descriptive statistics same as for 
the primary PK parameters.  
12.3.3 
Safety Analysis(es) 
Safety variables will be summarized for the safety population. 
Adverse Event: 
Treatment Emergent adverse events (TEAEs), i.e. AEs that are emergent or that worsen after 
the first study product (test or reference) administration, will be summarized by presenting, for 
each treatment, the number and percentage of subjects having any AE, any AE in each 
MedDRA System Organ Class (SOC) and having each individual AE. The subset of AEs 
suspected of a relationship to study drug will be presented similarly. All treatment-emergent 
AEs will also be tabulated by severity. Any other information collected (e.g. action taken, 
duration, outcome) will be listed. Each AE will be attributed to the treatment taken most 
recently before the onset of the AE. Adverse events due to COVID-19 will be listed and 
tabulated separately. 
Vital signs: 
Vital signs including temperature will be summarized by time-point and treatment. Summary 
statistics will include mean, standard deviation, minimum, median, and maximum. No 
inferential statistics will be presented. Data will be listed with abnormal values flagged. 
Physical examination: 
Physical Examination data will be listed with abnormal values flagged. 
Laboratory tests: 
Safety Laboratory data will be listed with abnormal values flagged. 
Note: Laboratory data at the screening is considered source and will not be listed unless 
otherwise noted. 
Criteria for assessing safety: 
Vital signs, clinical safety laboratory tests and monitoring of adverse events will be used to 
assess the safety and tolerability of the study products. 
12.3.4 
Exclusion of Data from Analysis  
Subjects who deviate from the protocol will be identified and excluded from analyses as agreed 
by the biostatistician and clinical scientist or designee. *Exclusion of any data from the analyses 
will be determined during a Blind Data Review (BDR) Meeting prior to database lock.  Any 
reasons for exclusion from an analysis population will be listed, if applicable. 
* Exclusion of subjects with baseline > 5% of the Cmax will be determined after database lock 
and unblinding.

the course of these monitoring visits are resolved. 
13.2 
Quality Assurance 
To ensure compliance with GCP and all applicable regulatory requirements, GSKCH may 
conduct a quality assurance assessment and/or audit of the site records, and the regulatory 
agencies may conduct a regulatory inspection at any time during or after completion of the 
study.  
In the event of an assessment, audit or inspection, the investigator (and institution) must agree 
to grant the advisor(s), auditor(s) and inspector(s) direct access to all relevant documents and 
to allocate their time and the time of their staff to discuss the conduct of the study, any 
findings/relevant issues and to implement any corrective and/or preventative actions to address 
any findings/issues identified. 
The investigator(s) will notify GSKCH or its agents immediately of any regulatory inspection 
notification in relation to the study. Furthermore, the investigator will cooperate with GSKCH 
or its agents to prepare the study site for the inspection and will allow GSKCH or its agent, 
whenever feasible, to be present during the inspection. The investigator will promptly apply 
copies of the inspection finding to GSKCH or its agent. Before response submission to the 
regulatory authority, the investigator will provide GSKCH or its agents with an opportunity to 
review and comment on responses to any such findings.  
The sponsor will be available to help investigators prepare for an inspection. 
13.3 
Regulatory and Ethical Considerations 
13.3.1 
Institutional Review Board/ Ethics Committee  
It is the responsibility of the investigator to have prospective approval of the study protocol, 
protocol amendments, informed consent documents, investigator brochure/safety statement 
(including any updates) and other relevant documents, e.g. recruitment advertisements, if 
applicable, from the IRB/EC.  All correspondence with the IRB/EC should be retained in the 
investigator file.  Copies of IRB/EC approvals should be forwarded to GSKCH prior to the 
initiation of the study, and also when subsequent amendments to the protocol are made. 
The only circumstance in which an amendment may be initiated prior to IRB/EC approval is 
where the change is necessary to eliminate apparent immediate hazards to the subjects.  In that 
event, the investigator must notify the IRB/EC and GSKCH in writing immediately after the 
implementation. 
13.3.2 
Ethical Conduct of the Study 
The study will be conducted in accordance with the protocol and legal and regulatory 
requirements, as well as the general principles set forth in the International Ethical Guidelines 
for Biomedical Research Involving Human Subjects (Council for International Organizations 
of Medical Sciences 2002), International Ethical Guidelines for Health-Related Research 
Involving Humans (Council for International Organizations of Medical Sciences, 2016),

SOP-208661 Clinical Protocol Template v6.0

guidelines for GCP (ICH 1996 and revision 2), and the Declaration of Helsinki (World Medical 
Association 2013).  
In addition, the study will be conducted in accordance with the protocol, the ICH guideline on 
GCP, and applicable local regulatory requirements and laws. 
13.3.3 
Subject Information and Consent 
All parties will ensure protection of subject personal data and will not include subject names or 
other identifiable data in any reports, publications, or other disclosures, except where required 
by laws.  
When study data are compiled for transfer to GSKCH and other authorized parties, subject 
names, addresses, and other identifiable data will be replaced by numerical codes based on a 
numbering system provided by GSKCH in order to de-identify study subjects.   
Note that the use of initials should be avoided.   
The study site will maintain a confidential list of subjects who participated in the study, linking 
each subject’s numerical code to his or her actual identity.  In case of data transfer, GSKCH 
will maintain high standards of confidentiality and protection of subjects’ personal data 
consistent with applicable privacy laws. 
The informed consent documents must be in compliance with ICH GCP, local regulatory 
requirements, and legal requirements, including applicable privacy laws. 
The informed consent documents used during the informed consent process must be reviewed 
and approved by the sponsor, approved by the IRB/EC before use, and available for inspection. 
The investigator must ensure that each study subject, is fully informed about the nature and 
objectives of the study and possible risks associated with participation.  
The investigator, or a person designated by the investigator, will obtain written informed 
consent from each subject before any study-specific activity is performed.  Both investigator 
and subject will retain the original of each subject's signed informed consent document. 
13.3.4 
Subject Recruitment  
Advertisements approved by IRBs/ECs and investigator databases may be used as recruitment 
procedures.  Use of ethics committee approved, generic, prescreening questionnaire to assess 
basic subject characteristics to determine general eligibility for this study is allowed.  This 
generic questionnaire may be used by sites as a phone script and/or to review internal databases 
to identify subjects.   
GSKCH will have an opportunity to review and approve the content of any study recruitment 
materials directed to potential study subjects before such materials are used.  
13.3.5 
Reporting of Safety Issues and Serious Breaches of the Protocol or 
ICH GCP  
Within GSKCH a serious breach is defined as a breach likely to affect to a significant degree 
the safety and rights of a subject or the reliability and robustness of the data generated in 
GSKCH-sponsored human subject research studies.  
In the event of any prohibition or restriction imposed (i.e., clinical hold) by an applicable 
competent authority in any area of the world, or if the investigator is aware of any new

Page 80 of 85 
information that might influence the evaluation of the benefits and risks of the investigational 
product, GSKCH should be informed immediately.  
In addition, the investigator will inform GSKCH immediately of any urgent safety measures 
taken by the investigator to protect the study subjects against any immediate hazard, and of any 
serious breaches of this protocol or of ICH GCP that the investigator becomes aware of. 
13.4 
Posting of Information on Publicly Available Clinical Trial 
Registers 
Study information from this protocol will be posted on publicly available clinical trial registers 
before enrollment of subjects begins in accordance with applicable GSKCH processes. 
GSK intends to make anonymized subject-level data from this trial available to external 
researchers for scientific analyses or to conduct further research that can help advance medical 
science or improve patient care. This helps ensure the data provided by trial participants are 
used to maximum effect in the creation of knowledge and understanding 
13.5 
Provision of Study Results to Investigators 
Where required by applicable regulatory requirements, an investigator signatory will be 
identified for the approval of the clinical study report.  The investigator will be provided 
reasonable access to statistical tables, figures, and relevant reports and will have the opportunity 
to review the complete study results at a GSKCH site or other mutually-agreeable location. 
GSKCH will also provide the investigator with the full summary of the study results.  The 
investigator is encouraged to share the summary results with the study subjects, as appropriate. 
The procedures and timing for public disclosure of the results summary and for development of 
a manuscript for publication will be in accordance with GSKCH Policy. 
A manuscript will be progressed for publication in the scientific literature if the results provide 
important scientific or medical knowledge. 
13.6 
Records Retention 
Following closure of the study, the investigator must maintain all site study records (except for 
those required by local regulations to be maintained elsewhere), in a safe and secure location.   
The records (study/ site master file) must be maintained to allow easy and timely retrieval, when 
needed (e.g. for a GSKCH audit or regulatory inspection) and must be available for review in 
conjunction with assessment of the facility, supporting systems, and relevant site staff. 
Where permitted by local laws/regulations or institutional policy, some or all of these records 
can be maintained in a format other than hard copy (e.g. microfiche, scanned, electronic); 
however, caution needs to be exercised before such action is taken.  
The investigator must ensure that all reproductions are legible and are a true and accurate copy 
of the original and meet accessibility and retrieval standards, including re-generating a hard 
copy, if required.  Furthermore, the investigator must ensure there is an acceptable back-up of 
these reproductions and that an acceptable quality control process exists for making these 
reproductions. 
The investigator must assure that the subject’s anonymity will be maintained.  On CRFs or other 
documents submitted to GSKCH, subjects should not be identified by their names or initials, 
but by an identification code. The investigator should keep a separate log of subjects’ codes,
