Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Description of intervention(s) / exposure
This study is a Phase I, single-center, single-dose, open-label, randomized, four way cross-over trial in 28 healthy adult participants. After an initial Screening Period, within 14 days of randomization, there will be four Study Periods each separated by a Washout Period of 7 days and a subsequent 7 days of final Follow-up Period, after the completion of the 4 study periods


The main objectives of the study are:
- to evaluate the pharmacokinetic parameters (Cmax, AUCtot, Tmax and t1/2) of 1000 mg paracetamol and 300 mg ibuprofen, when taken alone, or when taken in combination as 2 tablets of under fasting conditions
and
- to describe the effect of food on the pharmacokinetic profile of the combination when taken as two tablets (paracetamol 1000 mg + ibuprofen 300 mg).

All study medications (paracetamol 1000 mg, ibuprofen 300 mg and their combination) will be administered orally.

Participants will be fasted for at least 10 hours overnight before dosing and for 4 hours post dosing. Participants will be provided with standard meals from 4 hours post dose.
Drug assays will be carried out using validated chromatographic methods developed specifically for the determination of paracetamol and ibuprofen.
Participants allocated to receive the treatment under fed conditions will receive 30 minutes before the administration of the study drug a standardised high-fat, high-calorie meal. No additional food will be allowed for at least 4 hours after dosing

Outcomes
Primary outcome [1] 290704 0
- To define the pharmacokinetic parameters of 1000 mg paracetamol and 300 mg ibuprofen each one alone, or in combination as 2 tablets including:Cmax, Tmax, T1/2, AUC(0-t), AUC(0-inf)
Timepoint [1] 290704 0
Single dose study measuring plasma concentrations over 5, 15, 30, 45 minutes and 1, 1.25, 1.5, 2, 3, 6, 8, 10 and 12 hours after study drug administration
Primary outcome [2] 290712 0
To compare the AUC(0-t) and AUC(0-inf) and Cmax values following fed and fasting administration of 2 tablets of a fixed dose combination of paracetamol 1000 mg + 300 mg ibuprofen to provide an estimate of food effect
Timepoint [2] 290712 0
Single dose study measuring plasma concentrations over 5, 15, 30, 45 minutes and 1, 1.25, 1.5, 2, 3, 6, 8, 10 and 12 hours after study drug administration
Secondary outcome [1] 305071 0
Safety will be evaluated during each study period, and for 7 days following study drug administration.
An acute safety evaluation will be performed during each study period by recording spontaneously reported adverse events and by clinical assessments, including measurements of blood pressure and heart rate.
At screening and at the end of each study period an additional blood sample will be taken for haematology and biochemistry assessment.
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 paracetamol adverse effects (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] 305071 0
Safety will be evaluated at screening and at the end of each study period and for 7 days following the last dose of the study drug administration.

Statistical methods / analysis
The pharmacokinetic parameters Cmax, AUC (0-t), AUC (0-8), Tmax and t1/2 will be derived from the plasma concentration vs. time data using non-compartmental methods. Plasma concentrations for each dose at each time and the pharmacokinetic parameters will be summarised using standard descriptive statistics, including means, medians, geometric means, ranges, inter-quartile ranges, standard deviations and standard errors.

The bioavailability of the fed vs. fasted pharmacokinetic parameters Cmax, AUC(0-t) and AUC(0-8) will be determined from the 90% confidence intervals for the ratios of the parameters calculated using the residual variance from an ANOVA of loge transformed values using Kinetica program. These differences and CIs will be transformed back to original scale to provide an estimate of the relative bioavailability under fed state.
The ANOVA model will include terms for participant, period and formulation.
Bioavailability for the fed vs. fasted estimates will be calculated using only those participants who complete both relevant periods of the study for each comparison.
The additional pharmacokinetic parameter t1/2 will be summarized as means with 90% confidence intervals and compared between the different treatment groupsdoses using ANOVA as described above. Tmax will be summarized as medians with inter-quartile ranges and compared between formulations using Wilcoxon signed rank tests.
Safety 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 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 formulation maybe compared between formulations by ANOVA test using Systat program.
