Revision date:
20 February 2017
Mode of administration:
Oral administration with 240 mL water in standing position after an overnight fast 
of at least 10 hours
Duration of treatment:
Single dose in each treatment period separated by a wash-out phase of at least 
5 days
Endpoints
Primary endpoints: AUC0-tz and Cmax of ibuprophen and pseudoephedrine-HCl in 
plasma
Secondary endpoints: AUC0-∞of ibuprofen and pseudoephedrine-HCl in plasma; 
AUC0-tz, AUC0-∞and Cmax of R-ibuprofen and S-ibuprofen in plasma; and 
S/R-ibuprofen ratio for AUC0-tz (i.e., AUC0-tz S-ibuprofen / AUC0-tz R-ibuprofen)
of R- ibuprofen and S-ibuprofen in plasma
 
Safety criteria:
Physical examination, vital signs (BP, PR), 12-lead ECG, laboratory tests, adverse
events, tolerability assessment
Statistical methods:
The assessment of bioequivalence will be based upon two-sided 90% confidence
intervals (CIs) for the ratios of the geometric means (test/reference) for the 
primary and secondary endpoints using an acceptance range of 80.00-125.00%. 
This method is equivalent to the two one-sided t-tests procedure, each at the 5% 
significance level. The statistical model will be an ANOVA on the logarithmic 
scale including effects for ‘sequence’, ‘subjects nested within sequences’, ‘period’ 
and ‘treatment’. CIs will be calculated based on the residual error from ANOVA.
Descriptive statistics will be calculated for all endpoints.

INTRODUCTION
1.1
MEDICAL BACKGROUND
The common cold remains the most prevalent cause of acute morbidity. The cause is a viral 
infection, mostly by rhinovirus (up to 80%), corona virus (10-15%), parainfluenza (5%) or 
respiratory syncytial virus (5%) (R13-2920).
Looking at the typical course of a common cold it mostly starts with sore throat, followed 
by the simultaneous occurrence of rhino sinusitis and headache and/or muscle ache. While 
these symptoms gradually resolve, a dry cough may occur. In a later stage, the dry cough 
will develop into cough accompanied by thick tenacious secretion.
As the common cold is a disease of viral origin and usually benign in nature, symptomatic 
treatment is currently the mainstay in the therapy (P88-35100).
Different products are available on the market to treat the single symptoms such as:

Nasal decongestants against nasal congestion

Analgesics against headache, pain and fever

Antihistamines with a drying effect on the nasal passages and a decrease in sneezing

Cough suppressants against dry cough

Mucolytics and secretolytics against productive cough.
Symptomatic treatment with several individual non-prescription products may be 
inconvenient and present a significant additional cost to the patient. Indeed, in a survey in
250 community pharmacists in five European countries, 60% of the questioned pharmacists 
said that they preferred to treat themselves with a combination-product when suffering from 
a common cold (P97-6591).
Most symptoms of common cold are present sometime during the course of the cold, they 
appear, peak and resolve at different times. Nasal congestion and headache or muscle ache 
are often concurrent and both are considered as being bothersome by the patient.
Therefore the development of a fixed dose combination product of an analgesic and a nasal 
decongestant for the treatment of both concurrent and most bothersome symptoms was 
considered.
The combination of an analgesic and a decongestant for treatment of the symptoms 
associated with the common cold is based on the rational of relief from inflammation-based 
symptoms and nasal congestion.
Ibuprofen has been in therapeutic use for decades as nonsteroidal anti-inflammatory drug 
(NSAID). Pseudoephedrine has been in therapeutic use for decades as decongestant, 
respectively.
Their combination provides the cold and influenza sufferer with a convenient and effective 
treatment for the relief of their symptoms (P10-06083).

Based on positive experience with free combination of both compounds also fixed dose 
combination products with 200 mg ibuprofen and 30 mg pseudoephedrine-HCl have been 
developed and introduced into the European market.
In 2005 a mutual recognition process was granted with France as reference member state 
and Germany, Austria and Luxembourg as concerned member states. Local registrations 
were granted in UK in the 1990ies and Poland in 2004.
A fixed dose combination (FDC) product containing 400 mg ibuprofen free acid and 60 mg 
pseudoephedrine-HCl per film-coated tablet is going to be developed. This product should 
be registered via a decentralised procedure and marketed throughout Europe.
1.2
DRUG PROFILE
Ibuprofen
Ibuprofen is a NSAID of the arylpropionic acids class. This non-selective cyclooxygenase 
inhibitor exhibits marked stereo selectivity in pharmacokinetics (inversion, elimination) and 
pharmacodynamics, as the S-(+) enantiomer is considerably more potent and formed by 
unidirectional inversion of the R-(-)-enantiomer.
Main indications are the treatment of mild to moderate pain from various origins, in 
particular in the therapy of osteo-arthritis, rheumatoid arthritis and soft-tissue disorders. In 
addition, antipyretic activity and short time inhibition of platelet aggregation were observed.
Absorption occurs rapidly and completely after oral administration. Absolute bioavailability 
is almost 100%. Individual peak plasma concentrations are observed within three hours after 
administration of the free acid, with mean values reported as one to two hours. Rate of 
absorption, and thus maximum plasma concentrations (Cmax), may be significantly 
influenced by formulation properties while total exposure (AUC) remains unaffected. The 
apparent volume of distribution is 0.1 to 0.2 L/kg. As this value approximates plasma 
volume, it is suggested that plasma protein binding (> 98%) is preferred to tissue binding.
Following oral administration, about 80% of an ibuprofen dose is recovered as hydroxyl-
and carboxy-metabolites, either conjugated or unconjugated, in the urine within 24 hours. 
Only about 10% is found in the faeces. The major metabolic pathway involves CYP 2C9 and 
probably CYP 2C8. Most important metabolites are 2-hydroxy- and carboxy-ibuprofen 
while 1- and 3- hydroxy-ibuprofen were found in only very small concentrations. No 
pharmacologically active metabolite is known.
Pharmacokinetics of ibuprofen is dose dependent. At doses greater than 600 mg, the 
unbound fraction of the drug increases, probably due to saturation of the protein binding, 
resulting in an increased clearance and less than proportional area under the curve. Mean 
terminal elimination half-life is reported as 2 hours. For additional information please refer
to RhinAdvil® Summary of Product Characteristics. Evidence for accumulation or time
dependency of pharmacokinetics after multiple dosing was not found.

There are some concerns about the use of NSAIDs. Much of these concerns are related to 
long-term therapy with higher doses in special indications such as e.g. rheumatoid arthritis. 
Ample safety data is available for indications other than upper respiratory tract infections. 
However, this data will not be addressed here in detail. One of the few studies providing 
safety information on the use of ibuprofen in the treatment of cold and flu symptoms was 
reported recently.
In a double-blind randomised study, the tolerability of ibuprofen (up to 1.2 g daily), 
acetylsalicylic acid and acetaminophen (both up to 3 g daily) was investigated in 2815 
patients with mild to moderate pain resulting from cold/flu symptoms or sore throat for 
seven days. The main outcome was the rate of significant adverse events (SGAE). Rates of 
SGAE for ibuprofen, acetylsalicylic acid and paracetamol were respectively 12.0%, 15.7% 
and 12.3%. Ibuprofen was significantly better tolerated than acetylsalicylic acid (p=0.02) 
and showed comparable tolerability compared to paracetamol. The latter was also true for 
total digestive system events and for abdominal pain and dyspepsia. For all other adverse 
events the results were consistent with SGAEs, i.e. comparable proportions of patients in the 
ibuprofen and paracetamol groups and higher percentages of patients in the acetylsalicylic 
acid group than in the ibuprofen group. In conclusion patients with mild to moderate pain 
resulting from cold/flu symptoms or sore throat, ibuprofen used in over-the- counter is well 
tolerated (P04-01312).
Ibuprofen has an excellent safety profile in multiple-dose use with a frequency of 
gastrointestinal adverse events comparable to placebo.
Pseudoephedrine
Pseudoephedrine is a natural alkaloid, commonly manufactured by yeast fermentation. This 
sympathomimetic drug exhibits weak agonist activity at α- and β-adrenergic receptors and 
initiates release of endogenous norepinephrine from storage vesicles in presynaptic neurons. 
Thus, it is used as decongestant of mucous membranes.
The compound is rapidly and completely absorbed after oral administration with peak 
plasma concentrations occurring within 20 to 120 minutes. No information is available on 
plasma protein binding of pseudoephedrine, the apparent volume of distribution is reported 
as 2 −3.3 L/kg.
Pseudoephedrine is metabolised in the liver, but only to a small extent. Main metabolite is 
the pharmacologically active nor-pseudoephedrine. Between 70 and 90% of a given dose is 
excreted unchanged in the urine, only 1% as nor-pseudoephedrine.
Mean terminal elimination half-life is reported between five and six hours, individual values 
of up to 8 hours have been observed (R09-2316). Obviously, pH of the urine exhibits certain 
impact on urinary excretion with normal values at pH of 5 to 6. Higher and lower pH-values 
may increase or decrease half-life significantly due to changes in solubility and tubular 
reabsorption.
In a meta-analysis of 2 repeated dose studies using pseudoephedrine for the symptomatic 
treatment of the common cold, no overall differences in the risk of adverse events compared

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
Ibuprofen and pseudoephedrine are being used therapeutically for decades as NSAID and
decongestant, respectively.
Also combinations of pseudoephedrine with NSAID or antihistamines are common.
Based on positive experience with free combination of both compounds, also fixed dose
combination products with 200 mg ibuprofen and 30 mg pseudoephedrine-HCl have been 
developed and introduced into the market in some European countries.
Marketing Authorisation Application in the EU is planned for a fixed dose combination 
product as film coated tablets containing 400 mg of ibuprofen and 60 mg of 
pseudoephedrine as the test product.
Bioequivalence to RhinAdvil® as reference product, an approved and marketed product in 
France, Germany, (in the past also in Austria, Belgium and Luxumburg) will be assessed 
by means of a clinical phase I study.
Rationale of the study is to establish bioequivalence of the test product to the reference 
product.
2.2
TRIAL OBJECTIVES
2.2.1
Primary objective
To demonstrate the bioequivalence of a fixed dose combination tablet containing
400 mg Ibuprofen and 60 mg Pseudoephedrine-HCl vs. RhinAdvil® (2 tablets containing 
200 mg Ibuprofen and 30 mg Pseudoephedrine-HCl) as a fixed dose combination tablet with 
respect to the analytes, ibuprofen and pseudoephedrine.
2.2.2
Secondary objective
To assess the bioequivalence of a fixed dose combination tablet containing
400 mg Ibuprofen and 60 mg Pseudoephedrine-HCl vs. RhinAdvil® (2 tablets containing 
200 mg Ibuprofen and 30 mg Pseudoephedrine-HCl) as a fixed dose combination tablet with 
respect to R- and S-ibuprofen (enantiomers of ibuprofen).
2.3
BENEFIT – RISK ASSESSMENT
Participation in this bioequivalence study is without any therapeutic benefit for the healthy 
subjects. Their participation in the study, however, is of importance for the development of a 
new oral fixed dose combination of nonsteroidal anti-inflammatory drug (NSAID) and 
decongestant containing Ibuprofen 400 mg and Pseudoephedrine 60 mg.

The subjects are exposed to:

the risks of the study procedures

the known risks related to the exposure with the study medication
The use of an indwelling cannula for the purpose of blood sampling may be accompanied 
by mild bruising and also, in rare cases, by transient inflammation of the wall of the vein. 
After initial irritation, the presence of an indwelling cannula is usually painless and hardly 
noticeable. The same applies to vein puncturing for further blood sampling. In rare cases a 
nerve might be injured while inserting the cannula. This could be followed by paresthesia, 
reduced sensibility or pain for a long-term period.
The total volume of blood withdrawn during the entire study will be about ~ 362.5 ml. No 
safety related risk is expected from this blood withdrawal.
Drug related risks
Ibuprofen:
Reported main side effects of Ibuprofen are:
Agranulocytosis, haemolytic anaemia, dysopia, dyspepsia, epigastralgia,
gastrointestinal bleeding, impaired gastrointestinal motility, nausea, vomiting,
oedema, hypersensitivity, aseptic meningitis, increased levels of transaminase,
dizziness, headache, renal dysfunction, oliguria, asthma, progression of chronic
urticaria, pruritus, skin eruption, rash, erythema multiforme, angioedema.
Pseudoephedrine:
Reported main side effects of pseudoephedrine-HCl are:
Palpitations, tachycardia, narrow-angle glaucoma, dry mouth, nausea, vomiting, rare
cases of haemorrhagic stroke, headache, convulsion*, anxiety, restlessness*,
abnormality in behaviour*, hallucinations*, dysuria, retention of urine, sweating,
exanthema, pruritus, urticaria, hypertony
*have been reported rarely, particularly in children
For further detailed information, please refer to the (RhinAdvil® Summary of Product
Characteristics)
Overall Risk – Benefit assessment
Overall the risk for subjects participating in this trial is considered to be low and 
acceptable. Because of the anticipated benefit that a successful clinical development of the 
film coated fixed dose combination tablet containing ibuprofen 400 mg and 
pseudoephedrine-HCl 60 mg (Test Product) could provide patients a respectable amount of 
release of the symptoms associated with common cold. The sponsor feels the benefit of a 
successful clinical development of one film coated fixed dose combination tablet to 
outweigh the risk.

The study will be performed as an open-label, single dose, randomised, laboratory blind, 
two-way crossover trial.
The following treatments will be administered in the fasting state:
Test (T):
Film coated fixed dose combination tablet containing
Ibuprofen 400 mg and Pseudoephedrine 60 mg
Reference (R):
RhinAdvil® two fixed dose combination tablets containing
Ibuprofen 200 mg and Pseudoephedrine 30 mg
The two treatment sequences T-R and R-T will be randomly allocated to the subjects.
3.1.1
Administrative structure of the trial
The trial is sponsored by Boehringer Ingelheim (BI).
The conduct of the study will be monitored by a representative of the Sponsor to ensure 
compliance with applicable regulatory requirements and GCP. The summary of the 
documentation of the monitoring visits will form part of the study documentation and will be 
archived as such.
Safety Reporting will be done according to BI SOPs and will be described further in
Section 5.3.6.2.
Tasks and functions assigned in order to organise, manage, and evaluate the trial are defined 
in accordance with PAREXEL standard procedures.
A local laboratory service will be used in this trial. Procedures will be in accordance with 
PAREXEL standard procedures. Tests not performed by the local laboratory will be 
outsourced to PAREXEL’s preferred vendor laboratory for analysis. The results from the 
preferred vendor laboratory will be transmitted to ClinBase™and electronically transferred 
to Data Management.
Data Management and Statistical Evaluation will be done according to PAREXEL standard 
procedures. PK Analysis will be done according to non-compartmental analyses guidance and 
the TSAP.
A list of SOPs will be contained in the ISF.

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP(S)
For bioequivalence studies, the crossover design is viewed favourably due to its efficiency: 
since each subject serves as his own control, the comparison between treatments is based 
on a comparison within subjects rather than between subjects. This means that the inter-
subject variability is removed from the comparison between treatments [R94-1529].
The open-label treatment is not expected to bias results, since the study endpoints are derived 
from measurement of plasma concentrations of the analytes, which are provided by a 
bioanalytical laboratory that is blinded to treatment allocation.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 56 healthy male and female subjects will be randomised in the study, to 
complete with at least 48 evaluable subjects. At least 16 of each gender should be included in 
the evaluable population. Subjects will be recruited from the subjects’ pool of Bloemfontein 
Early Phase Clinical Unit, PAREXEL International (South Africa).
A log of all patients enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not.
3.3.1

The subject has to take any concomitant drugs interfering with the study medication
The subject is no longer able to participate for other medical reasons (e.g. pregnancy, surgery, 
adverse events or other diseases)
In addition to these criteria, the investigator may discontinue subjects at any time based on 
his or her clinical judgment.
A subject can also be removed from the trial, if eligibility criteria are being violated or if the 
subject fails to comply with the protocol (for instance, by non-adherence to dietary rules, or 
non-attendance at study assessments.
If a subject is removed from or withdraws from the trial prior to the first administration of trial 
medication, the data of this subject will not be entered in the electronic case report form 
(eCRF) or trial database and will not be reported in the clinical trial report (CTR). If a subject 
is removed from or withdraws from the trial after the first administration of trial medication, 
this will be documented and the reason for discontinuation must be recorded in the eCRF; in 
addition, the data will be included in the eCRF/trial database and will be reported in the CTR. 
At the time of discontinuation, a complete end-of-trial examination will be performed, if 
possible, and the information will be recorded in the eCRF. If the discontinuation occurs 
shortly after administration, the discontinued subject should be evaluated for AEs and 
concomitant therapies if possible as long as measureable drug levels are still likely to be 
present, assuming the subject agrees to such an evaluation.
If it is known that a subject becomes pregnant during the trial, administration of the trial 
medication is to be stopped immediately, and the subject is to be removed from the trial. The 
subject is to be followed until she has given birth or until the end of the pregnancy. The 
subject’s data are to be collected until the end of the trial (last visit of last subject) and 
reported in the CTR.
3.3.4.2
Replacement of subjects
Subjects who withdraw or are withdrawn from the study will not be replaced, unless fewer 
complete the study than the estimated number of evaluable subjects.
If a subject is replaced, the replacement will be allocated the subject number of 500 plus the 
subject number being replaced (e.g., Subject
will be replaced by
). The subject numbers
being replaced will be selected such that the replacement subjects receive the same treatment
sequence as the withdrawn subjects and the sequence balance is maintained.
Replacement subject must preferably be of the same gender as the withdrawn subjects, if this is
needed to secure the requirement that at least 1/3 of each gender should complete the study.
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial site
at any time for the following reasons:

5.3.5
Medical Examination / Global assessment
At the screening visit, the medical examination will include documentation of subject 
information, informed consent, demographics including height and weight, smoking and 
alcohol history, relevant medical history and concomitant medication, review of inclusion 
and exclusion criteria, review of vital signs (blood pressure, pulse rate and body 
temperature), 12-lead ECG, laboratory tests (including a pregnancy test in females), and a 
physical examination.
The end- of-study examination will include review of vital signs, 12-lead ECG, laboratory 
tests (including pregnancy test), and a physical examination. Adverse events and 
concomitant therapies will be assessed throughout the study.
The investigator will assess tolerability based on adverse events and the laboratory 
evaluation. Tolerability will be assessed by the investigator according to the categories 
“good”, “satisfactory”, “not satisfactory”, and “bad”.
5.3.6
Assessment of adverse events
The subjects will be required to report spontaneously any AEs as well as the time of 
onset, duration and intensity of these events. The clinical judgment of the intensity will 
be made by the physician.
In addition, each subject will be assessed regularly by the medical staff throughout the 
clinical trial and whenever necessary as deemed by the investigator. Assessment will be 
made using non-specific questions such as “How do you feel?” Specific questions will be 
asked wherever required or useful to more precisely describe an AE.
A written record of all AEs shall be kept by the investigator in charge of the study. Records 
of adverse events shall include data on the time of onset, end time and intensity of the event
as well as any treatment or action required for the event and its outcome.
5.3.6.1
Definitions of AEs
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical
investigation subject administered a medicinal product 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), symptom, or disease temporally

associated with the use of a medicinal product, whether or not considered related to the 
medicinal product.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and
unintended. Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility. Adverse reactions may arise 
from use of the product within or outside the terms of the marketing authorisation or from 
occupational exposure. Conditions of use outside the marketing authorization include off-label 
use, overdose, misuse, abuse and medication errors.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which:

results in death,

is life-threatening, this 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 that hypothetically might have caused 
death if more severe.

requires inpatient hospitalisation or

prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, or

is a congenital anomaly / birth defect, 
or

is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Medical and scientific judgement should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalisation but might jeopardise the patient 
or might require intervention to prevent one of the other outcomes listed above. Examples of 
such events are intensive treatment in an emergency room or at home for allergic 
bronchospasm, blood dyscrasias or convulsions that do not result in hospitalisation or 
development of dependency or abuse. Any suspected transmission via a medicinal product of an 
infectious agent is also considered a serious adverse reaction.
AEsconsidered“AlwaysSerious”
Cancers of new histology and exacerbations of existing cancer must be reported as a serious
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs, which by their nature, can always be 
considered to be “serious” even though they may not have met the criteria of an SAE as given 
above.
A copy of the latest list of “Always Serious AEs” will be provided to you upon request. These 
events should always be reported as SAEs as described above.

Adverse events of special interest (AESIs)
No AESIs have been defined for this trial.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Enough discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
The definition of an adverse reaction implies at least a reasonable possibility of a causal
relationship between a suspected medicinal product and an adverse event. An adverse reaction, 
in contrast to an adverse event, is characterised by the fact that a causal relationship between a 
medicinal product and an occurrence is suspected.
Medical judgment should be used to determine the relationship, considering all relevant factors, 
including pattern of reaction, temporal relationship, de-challenge or re-challenge, confounding 
factors such as concomitant medication, concomitant diseases and relevant history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship could 
be:

The event is consistent with the known pharmacology of the drug

The event is known to be caused by or attributed to the drug class.

A plausible time to onset of the event relative to the time of drug exposure.

Evidence that the event is reproducible when the drug is re-introduced

No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).

The event is typically drug-related and infrequent in the general population not exposed 
to drugs (e.g. Stevens-Johnson syndrome).

An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship could 
be:

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks of 
drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)

Continuation of the event despite the withdrawal of the medication, taking into account 
the pharmacological properties of the compound (e.g. after 5 half-lives).

Of note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger.

Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned).

Disappearance of the event even though the study drug treatment continues or remains

Adverse event collection and reporting
AE Collection
The Investigator shall maintain and keep detailed records of all AEs.
The following must be collected and documented on the appropriate CRF(s) by the
Investigator:

From signing the informed consent onwards, until individual patient’s end of trial:
-all AEs (serious and non-serious).

After the individual patient’s end of trial:
the Investigator does not need to actively monitor the patient for AEs but should only 
report relevant SAEs of which the Investigator may become aware of.
The residual effect period (REP) for ibuprofen and pseudoephedrine when measurable drug 
levels or PD effects are still likely to be present, was defined as 48 hours after administration 
(based on half-lives of 3 and 8 hours of ibuprofen and pseudoephedrine, respectively). However,
for assigning AEs to treatments a conservative approach will be used, i.e. post- treatment periods
based on REP will not be defined (see Section 7.3.3).
AE reporting to sponsor and timelines
The Investigator must report SAEs, and non-serious AEs which are relevant for the reported
SAE, on the BI SAE form via fax immediately (within 24 hours) to the sponsor’s unique entry
point (country specific contact details will be provided in the ISF). The same timeline applies if
follow-up information becomes available. In specific occasions the Investigator could inform the
sponsor upfront via telephone. This does not replace the requirement to complete and fax the BI
SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial information.
Information required
For each AE, the Investigator should provide the information requested on the appropriate eCRF
pages and the BI SAE form. The Investigator should determine the causal relationship to the 
trial medication.
The following should also be recorded as an (S)AE in the eCRF and SAE form (if applicable):

Worsening of pre-existing conditions

Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the Investigator.

If such abnormalities already pre-exist prior trial inclusion they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after individual patient’s end of trial must be followed up 
until they have resolved, have been sufficiently characterised, or no further information can be 
obtained.

In rare cases pregnancy may occur in a clinical trial. Once a patient has been enrolled into this 
clinical trial and has taken trial medication, the Investigator must report immediately (within 
24 hours) a potential drug exposure during pregnancy (DEDP) to the sponsor’s unique entry 
point (country-specific contact details will be provided in the ISF). The Pregnancy Monitoring 
Form for Clinical Trials (Part A) should be used.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring Form 
for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B).
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE, 
only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form is to be 
completed. If there is an SAE associated with the pregnancy an SAE form must be completed in 
addition.

Blood samples are routinely placed on ice between sample collection and centrifuging. Within
30 minutes of collection, centrifuging of blood samples will commence at approximately2700 g
within a range of 0C to 8C for 10 minutes. Thereafter, the supernatant of each sample will be
divided into 4 aliquots (2 aliquots of at least 0.4 mL plasma each for ibuprofen (including R- and 
S-ibuprofen) analysis, and 2 aliquots of at least 1.3 ml each for the determination of
pseudoephedrine) and transferred to labelled, plastic tubes. The plasma samples will be flash-
frozen on dry ice immediately after preparation. One of the two aliquots for each analyte will be
considered as a duplicate set in case of re-assay.
All sample tube labels will contain at least the following information: study number, analyte, 
time (protocol time and/or relative sampling time), subject number, blood sample number and 
treatment period. Plasma samples will be stored at approximately -20C until transfer to 
PAREXEL Bioanalytical Services Division (BASD). Pooled samples for concentration range 
estimation will be prepared according to PAREXEL SOPs. These range estimation samples 
originate from some of the blood samples collected for drug assays and may be used by the 
analytical laboratory to determine suitable quantification ranges.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. Time 
windows are permitted as follows:
General medical examination: at screening (1 to 21 days prior to the first study day) and at the 
end-of-study evaluation (within 7 days following the last trial procedure).
The tolerance for vital signs, ECG and laboratory tests will be provided in a Window Allowance 
Document.
For planned individual plasma concentration sampling times refer to the Flow_Chart. While 
these nominal times should be adhered to as closely as possible, the actual sampling times will 
be recorded and used for determination of pharmacokinetic parameters.
Study measurements and assessments scheduled to occur on study day 1 prior to drug 
administration have to be performed and completed at least 15 minutes prior to drug 
administration. This will be addressed in the Window Allowance Document. If a subject misses 
an appointment, it will be rescheduled if possible.

STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
7.1
STATISTICAL DESIGN - MODEL
The statistical methodology below describes the statistical analysis as it is foreseen when the
study is being planned. A SAP will be prepared with more details on the planned statistical
methodology and will be finalized prior to database lock.
If applicable, deviations from the original SAP and reasons for the deviations, as well as any
alternative or additional statistical analysis that may be performed, will be documented in
the CTR.
The objective of the trial is to establish the bioequivalence of Test treatment (T), one fixed 
dose combination tablet compared to reference treatment (R) RhinAdvil® two fixed dose 
combination tablets given to healthy male and female subjects.
The study will be conducted according to an open-label, randomised, single-dose, two-way 
crossover design. For bioequivalence studies, the crossover design is viewed favourably due
to its efficiency: since each subject serves as his/her own control, the comparison between
formulations is based on a comparison within subjects rather than between subjects. This 
means that the inter-subject variability is removed from the comparison between formulations 
(R94-1529).
Bioequivalence is primarily to be determined on the basis of the endpoints AUC0-tz and Cmax.
of the analytes, ibuprofen and pseudoephedrine-HCL.  Additionally, AUC0-∞and other
secondary endpoints that are described in Section 5.1.2 will be calculated undergoing the same 
analyses as described for the primary endpoints (estimation of relative bioavailability). The
derivation of the PK parameters will be specified in the TSAP.
Safety and tolerability will be determined on the basis of the following parameters: adverse 
events, laboratory tests, physical examination, vital signs (BP, PR), 12-lead ECG, and 
assessment of tolerability by the investigator.
The statistical model used for the analysis of the AUC0-tz, Cmax and AUC0-∞will be an 
ANOVA (analysis of variance) model on the logarithmic scale. This model will include 
effects accounting for the following sources of variation: ‘sequence’, ‘subjects within 
sequences’, ‘period’ and ‘treatment’. All effects will be considered as fixed. The model is 
described by the following equation
yijkm = + i + sim + j + k + eijkm, where
yijkm = logarithm of response (AUC or Cmax) measured on subject m in sequence i
receiving treatment k in period j,
= the overall mean, i = the ith sequence effect, i = 1, 2,

j = the jth period effect, j = 1, 2,
k = the kth treatment effect, k = 1, 2,
eijkm = the random error associated with the mth subject in sequence i who received 
treatment k in period j.
7.2
NULL AND ALTERNATIVE HYPOTHESES
Bioequivalence is established by using the average bioequivalence method to ensure that the
ratio of the primary endpoints of the two treatments (T/R) is contained within a pre-specified
acceptance range (see below). This goal is accomplished by testing the below hypothesis on the
log scale.
Null hypothesis H0 (Inequivalence): T R or
T R 

(i.e. the difference of the population average responses is either less than or equal to 
the lower bound or greater than or equal to the upper bound of the acceptance 
range),
Alternative hypothesis Ha (Equivalence):
T R 

(i.e. the difference of the population average responses is both greater than the lower bound and
less than the upper bound of the acceptance range), where T and R are the population average 
responses of the log-transformed measures for the formulations Test and Reference, and is the
bioequivalence limit that defines the acceptance range for AUC and Cmax on the logarithmic scale
In this trial, is taken to be ln(1.25). This translates to an acceptance range of 80 to 125% for the
geometric mean of the ratio of the parameters on the original scale.
This hypothesis and its alternative can be decomposed into two one-sided null hypotheses, H01
and H02, with their accompanying alternatives:
H01:
T R vs.
Ha1:
µT  µR   δ
H02:
µ T µ R δ
vs.
Ha2:
µ T µ R δ
Due to the nature of normal-theory confidence intervals, the test of the null hypothesis at the =
0.05 level is equivalent to carrying out two one-sided tests of the above null hypotheses each at
the = 0.05 level of significance. The rejection of both null hypotheses H01 and H02 at the =
0.05 level is equivalent to the inclusion of the 90% confidence interval for T R in the
acceptance range.

PLANNED ANALYSES
7.3.1
Primary analyses
The PK analysis population (PKS, PK set) will include all treated subjects that provide 
observations for both periods for at least one primary endpoint evaluable (see below) and 
without any major protocol deviation thought to interfere with the absorption, distribution,
metabolism, and excretion of the compound to be measured. PK parameters for subjects who
discontinue after a single treatment may be presented in the listings but will not be used for
summary statistics or any statistical analysis.
The total ibuprofen and pseudoephedrine pharmacokinetic parameters AUC0-tz and Cmax of test
(T) and reference will be log transformed (natural logarithm) prior to fitting the ANOVA
model. The difference between the expected means for log(T)-log(R) will be estimated by the 
difference in the corresponding Least Square Means (point estimate) and two-sided 90% 
confidence intervals based on the t-distribution will be computed. These quantities will then be
back-transformed to the original scale to provide the point estimate and 90% CIs for each
endpoint.
A claim of bioequivalence will be made if the 90% confidence intervals of the geometric 
means of both ratios AUC0-tz and Cmax of ibuprofen and pseudoephedrine-HCL are contained
in the pre-defined acceptance range.
7.3.2
Secondary analyses
The parameter AUC0-∞of total ibuprofen and pseudoephedrine will statistically be assessed
using the same methods as described for the primary endpoints.
Additionally, R- and S-ibuprofen pharmacokinetic parameters AUC0-tz, AUC0-∞and Cmax will
statistically be assessed using the same methods as described for the primary endpoints
(analysis of relative bioavailability).  The same methods will be applied for the 
S/R-ibuprofen ratio for AUC0-tz.
Concentrations will be used for graphs and calculations in the format that is reported in the 
bioanalytical report.
Plasma concentrations will be plotted graphically versus time for all subjects as listed in the 
drug plasma concentration-time tables. For the presentation of the mean profiles, the geometric
mean and the planned blood sampling times will be used.
The following descriptive statistics will be calculated for plasma concentrations as well as for 
all primary and secondary pharmacokinetic parameters: N, arithmetic mean, standard 
deviation, minimum, median, maximum, arithmetic coefficient of variation, geometric mean,
geometric coefficient of variation. The data format for descriptive statistics of concentrations
will be defined in the TSAP.

7.3.3
Safety analyses
All subjects who received at least one dose of study drug will be included in the safety evaluation
(safety population). Safety analyses will be descriptive in nature and will be based on BI
standards
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs). In 
general, all adverse events occurring between start of treatment and end of the residual effect 
period are considered ‘treatment-emergent’. The residual effect period (REP) was defined as
2 days which is shorter than the wash-out period. In the special setting of single doses in the 
cross-over design AEs will be assigned to treatments as detailed below without taking into 
account the residual effect period separately.
AEs will be assigned to treatments based on start date/time of the AE in relation to dosing in 
each period.

All AEs with start date/time prior to dosing in period 1 are pre-treatment AEs and will 
be assigned to screening.

All AEs with start date/time after the date/time of dosing in period 1, but before dosing 
in period 2, will be assigned to the treatment received in period 1.

AEs with start date/time after the date/time of dosing in period 2 will be assigned to the 
treatment received in period 2.
With this definition AEs occurring in wash-out will be assigned to the treatment received in 
period 1. AEs up to the follow-up visit will be assigned to the treatment received in period 2 if
the start date/time of the AE was after dosing in period 2.
Independent of this rule, the relationship of an adverse event to the treatments will be assessed by
the investigator.
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Frequency, severity, and causal relationship of AEs will be tabulated by 
treatment, system organ class, and preferred term. SAEs, and other significant AEs 
(according to ICH E3) will be listed separately.
Global tolerability will be assessed by the Investigator.

specific time points will be calculated only when at least 2/3 of the individuals have
concentrations within the validated concentration range. The overall sample size to decide
whether the “2/3 rule” is fulfilled will be based on the total number of samples intended to be
drawn for that time point (i.e. BLQ, NR and NS are included).
7.5.3
Pharmacokinetic parameters
In the non-compartmental analysis, concentration data identified with NS and NR will not be
considered. BLQ in the lag phase will be set to zero. The lag phase is defined as the period
between time zero and the first time point with a concentration above the quantification limit.
All other BLQ values of the profile will be ignored.
Data may/will be excluded from PK analysis (concentrations listed only) if any of the following
criteria are fulfilled:

The pre-dose concentration is greater than 5% of the corresponding Cmax in any given 
treatment period.

Subject experienced emesis within 2 x the reported median tmax for the analyte (Median 
tmax is to be determined excluding the subjects experiencing emesis).
Descriptive statistics of parameters are calculated only when at least 2/3 of the individual 
parameter estimates of a certain parameter are available. If the actual sampling time will not be
recorded or will be missing for a certain time point, the planned time will generally be used 
for this time point instead. Pharmacokinetic parameters which cannot be determined will be 
identified by "not calculated" (NC).
7.6
RANDOMISATION
Subjects will be randomised to one of the two treatment sequences (T-R, R-T) in a 1:1 ratio.
Stratification by gender will not be done.
The randomisation schedule will be provided by PAREXEL Biostatistics. The 
randomisation schedule will be generated utilizing the PROC PLAN procedure of SAS® 
software.
7.7
DETERMINATION OF SAMPLE SIZE
The intra-individual variability of the primary endpoints of both analytes was determined 
based on a similar internal study (1024.7) with the same test and reference products but lower
doses. For Cmax the coefficient of variation (gCV) was estimated below 19 % for both analytes,
while for AUC, the gCV for both analytes was lower than 12%. For Cmax the T/R ratio
estimate (gMean) was not lower than 91%, for AUC not greater than 105%.

Hence the sample size for this trial was determined based on the Cmax, accounting for multiple
testing of the two analytes, i.e. the overall power of the study is the product of the power of
the test of each analyte, as their endpoints are assumed to be uncorrelated. Using gCVs of 19
and 20% and a power of 95% for the single test (in order to achieve an overall power greater than 
90%) to reject the null hypothesis of bio-inequivalence for Cmax in favour of equivalence at the
5% level of significance is displayed in Table 7.7: 1 under various assumptions for the T/R-
subject ratio. The total sample size is double the size per sequence group.

90% for concluding equivalence (with respect to an acceptance range of 80-125%) assuming

crossover based on Cmax data of 1024.7 (ibuprofen)

This ratio reflects the median intra-subject ratio defined by exp(µT)/exp(µR) and is estimated by the
geometric mean of the intra-subject ratios
From the above table, a sample size of 48 will have a more than 90% power to conclude 
bioequivalence if the T/R ratio is not lower than 91%, the lowest ratio in study 1014.7 (Cmax of
ibuprofen). Accounting for up to 8 dropouts, a total of N = 48 + 8 = 56 subjects will be entered
into the study
The calculation was performed as described by Diletti et al (cf. R94-1445) using nQuery.

requirements. A data management plan (DMP) will be prepared to describe the work- and data-
flow within the clinical study. If applicable, sponsor-specific requests, timelines, versions for the
computer systems and the coding will be defined in the DMP. The DMP must be finalized before
data entry. Different levels of data validation checks may be developed based on the different
data sources. A data validation specification (DVS) may be created if not covered by standard
processes. In such case study-specific checks will be added to the standard checks that are
already available. If applicable the DVS must be finalized before data validation. The raw data
intended for further processing will be checked by standard routines or according to the DVS and
queries will be generated and sent to the investigator for answers. Corrections resulting from
these queries will be confirmed on the data clarification forms (DCFs). This process will be
repeated until no further discrepancies are found. The study monitor will confirm that all queries
have been closed out appropriately. The data will be then be declared as clean. Applicable
documentation will be stored in the study files. Only trained study staff will have access to the
clinical database and every change in data will have a full audit trail.

Description of change
Addition of a secondary trial objective to assess the 
bioequivalence of a fixed dose combination tablet 
containing 400 mg Ibuprofen and 60 mg 
Pseudoephedrine-HCl vs. RhinAdvil® (2 tablets 
containing 200 mg Ibuprofen and 30 mg 
Pseudoephedrine-HCl) as a fixed dose combination 
tablet with respect to R- and S-ibuprofen 
(enantiomers of ibuprofen).
Updating applicable sections of the trial protocol to 
provide for the added PK analyses of R- and 
S-ibuprofen.
Due to technical problems, document number 
extension needs to be -03 and due to second-step 
signature workflow needed, document number 
extension -04 is current.
Rationale for change
To add an additional secondary trial objective.
