Outcomes
Primary outcome [1] 305781 0
To evaluate and compare the pharmacokinetic parameters (Cmax, AUC0-t, AUC0-inf, Tmax, Kel and t1/2el) between test and reference products under fasting conditions
Timepoint [1] 305781 0
Blood samples (14) were collected before dose (0.00) and at 5 minutes (0.083 hours), 15 minutes (0.25 hours), 30 minutes (0.50 hours), 45 minutes (0.75 hours) and 1.00, 1.25, 1.50, 2.00, 3.00, 6.00, 8.00, 10.00 and 12.00 hours post dose. The total volume of blood draws did not exceed 420 ml.
Secondary outcome [1] 346522 0
To compare the safety and tolerability of test and reference products under fasting conditions.
An acute safety evaluation will be performed during each study period by recording spontaneously reported adverse events and by clinical assessments, including measurements of vital signs (blood pressure, heart rate, respiratory rate) and body temperature.
These measurements will be done at screening as well as prior, during and after each dosing period.
Vital signs will be measured pre-dose and approximately at 0.50, 1.00, 1.50, 2.00, 3.00, 4.00, 6.00 and 12.00 hours after study drug administration. Body temperature will be measured before dosing and approximately at the following times after dosing: 4th and 12th hour. Vital signs may be taken at other times if deemed necessary.
At screening and at the end of each study period an additional blood sample will be taken for haematology, biochemistry and serological assessment (only in screening).
Known NSAID adverse effects (i.e. GI ulceration, indigestion/stomach pain, GI bleeding, bronchospasm, water retention, renal failure, skin reactions and thromboembolic events), and known adverse effects of acetaminophen (i.e. clinical evidence of hepatotoxicity) will be compared between groups.
Adverse events will continue to be assessed up to 7 days after the last dose of the study medication by spontaneous reporting and at a final follow-up phone call.
Timepoint [1] 346522 0
Safety will be evaluated during each study period and for 7 days following study drug administation

Statistical methods / analysis
PK Analysis:
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-inf: The area under the plasma concentration versus time curve, from zero to infinity. AUC0-inf 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.
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
The actual times of blood sampling will be used for these calculations as per internal SOPs, DMU-001
Missing drug concentration data (value below LLOQ, missing value) will be treated as follows:
-Any missing concentration values are 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:
AEs will be collected for all randomized participants and will be listed with type of AE, severity and relationship for each treatment group, using the safety population. Adverse events data will be summarized for each formulation using frequencies and percentages (% of participants with each specific AE).
The haematology and biochemistry data collected pre-study and after each study period will be summarized descriptively using means, medians, standard deviations, ranges and 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 may be compared between treatments using repeated measures by ANOVA using Systat program.
