Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Each participant will be randomly allocated to receive a single dose of each of the intervention treatments, and the comparator treatment under fasting conditions in a three-way crossover sequence:

Intervention Treatments:
Treatment A: Paracetamol 500 mg & Ibuprofen 150mg Film-Coated Tablets (500 mg acetaminophen + 150 mg ibuprofen per film coated tablet)
Administration: Two tablets (given at the same time) as a single dose (total dose 1000 mg acetaminophen + 300mg ibuprofen) will be administered orally with 240 mL of water.

Treatment B: Xylometazoline hydrochloride (1 mg/mL; 0.138 mL per spray; 0.138 mL of 1mg/mL xylometazoline hydrochloride will give a calculated dose of 0.138 mg of xylometazoline hydrochloride per spray).

Administration: One spray per nostril, a total of two sprays will be administered as a single dose (total of 0.276 mL of xylometazoline hydrochloride delivered, total calculated dose of 0.276 mg of xylometazoline hydrochloride).

Participants will be fasted for at least 10 hours overnight before dosing and for 4 hours after dosing. Water will be restricted for 1 hour pre-dose and 1 hour post-dose (with the exception of water administered as part of dosing).
The test product will be administered under the site staff's supervision and the exact dosing time will be documented.

There will be three study periods each separated by a washout period of at least 7 days between two consecutive periods and a subsequent 7 days of final follow-up period.

Comparator / control treatment
The comparator treatment is described below:
Treatment C: Paracetamol 500 mg & Ibuprofen 150mg Film-Coated Tablets and Xylometazoline hydrochloride

Administration: Two tablets of Paracetamol 500 mg & Ibuprofen 150mg Film-Coated Tablets (given at the same time) as a single dose (total dose 1000 mg acetaminophen + 300mg ibuprofen) will be administered orally with 240 mL of water, and one spray per nostril, a total of two sprays of Xylometazoline hydrochloride (1 mg/mL; 0.138 mL per spray; 0.138 mL of 1mg/mL xylometazoline hydrochloride will give a calculated dose of 0.138 mg of xylometazoline hydrochloride per spray) will be administered as a single dose (total of 0.276 mg of xylometazoline hydrochloride), taken together in combination.

Participants will be fasted for at least 10 hours overnight before dosing and for 4 hours after dosing. Water will be restricted for 1 hour pre-dose and 1 hour post-dose (with the exception of water administered as part of dosing).
The test product will be administered under the site staff's supervision and the exact dosing time will be documented.


Pharmacokinetic parameters of Treatment C (Paracetamol & Ibuprofen + Xylometazoline hydrochloride), will be compared against the pharmacokinetic parameters of the individual components alone (Treatment A - Paracetamol & Ibuprofen, and Treatment B - Xylometazoline hydrochloride).

Participants will check-in to the Study Centre the evening prior to study drug administration and will stay for the duration of the Study Period (at least 12 hours after dosing). Each Study Period will consist of a Baseline Period (pre-dosing) and a Treatment Period. Safety will be evaluated during each study period, and for 7 days following study drug administration.

Pharmacokinetics
Statistical methods / analysis
On the basis of the concentration-time data, the following pharmacokinetic parameters will be estimated for acetaminophen, ibuprofen and xylometazoline from the plasma concentration against time data, using a non-compartmental model:
AUC0-t: The area under the plasma concentration versus time curve from time zero to the last measurable concentration, as calculated by the linear trapezoidal method.
AUC0-8: The area under the plasma concentration versus time curve, from zero to infinity. AUC0-8 is calculated as the sum of the AUC0-t plus the ratio of the last measurable concentration to the elimination rate constant (Ct/Kel).
Cmax: Maximum measured plasma concentration directly obtained from the experimental data of plasma concentration versus time curves, without interpolation.
Kel: Apparent first-order elimination or terminal rate constant calculated from a semi-log plot of the plasma concentration versus time curve. The parameter will be calculated by linear least-squares regression analysis using the last three (or more) non-zero plasma concentrations and excluding Cmax.
Tmax: Time of maximum measured plasma concentration. If the maximum value occurs at more than one point, Tmax is defined as the time of the first occurrence.
t1/2el: Time required for the plasma drug concentration to decrease by one half. This value is estimated from the elimination rate constant (Kel) calculated from the slope of the linear relationship between the loge concentration and time during the terminal elimination phase.

No value of Kel, AUC0-inf, AUC0-t /AUC0-inf or t1/2el will be reported for cases that do not exhibit a terminal log-linear phase in the concentration versus time profile.

The actual times of blood sampling will be used for these calculations as per internal SOPs, DMU-001, except the first six sampling points after dosing will be adjusted if there is a deviation more than 1 min.

Missing drug concentration data (value below LLOQ, missing value) will be treated as follows:
• Any missing concentration values are treated as missing and not included in the pharmacokinetic calculations.
• Values below LLOQ are treated as zero for all pharmacokinetic and statistical analyses.

Descriptive statistics, including the means, standard deviations, standard error of the mean and coefficient of variation, shall be reported for the plasma concentrations. For pharmacokinetic parameters, arithmetic means, standard deviations, standard error of the mean, minimum, median, maximum, coefficient of variation, inter-quartile ranges and geometric means shall be reported.

Safety Analysis
Adverse events data will be summarized for each treatment using frequencies and percentages (% of participants with each specific AE). Known NSAID specific AEs maybe compared between treatments as appropriate when frequencies are sufficient. Individual safety data will be listed by treatment.
The haematology and biochemistry data collected pre-study and after each period will be summarized descriptively using means, medians, standard deviations, ranges, frequencies and percentages as appropriate. Individual values outside normal ranges and considered clinically significant will be individually listed. Comparisons of the haematology and biochemistry measures associated with each treatment will be compared using repeated measures ANOVA using SPSS Software.
