Titles & IDs
Public title
Comparative assessment of the absorption of a generic formulation of a combination N-(4-hydroxyphenyl)acetamide/(RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension against two innovator formulations administered simultaneously of N-(4-hydroxyphenyl)acetamide oral suspension and (RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension conducted under fasting conditions in healthy volunteers.
Scientific title
A single dose, randomized, open label bioequivalence study of a generic formulation of 10ml of a combination 250/100 mg N-(4-hydroxyphenyl)acetamide/(RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension in a 2 way crossover comparison against two innovator formulations administered simultaneously of 5 ml of 250 mg of N-(4-hydroxyphenyl)acetamide oral suspension and 5 ml of 100 mg of (RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension conducted under fasting conditions in healthy volunteers.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The combination test formulation of 1 x 10 ml of 250/100 mg N-(4-hydroxyphenyl)acetamide/(RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension on one occasion. The intervention for this trial is the test oral suspension formulation.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with each dose).

Participants are required not to eat for 10 hours before dosing and to fast for approximately 4 hours after each dose.

Bathroom visits will be supervised to ensure no unauthorized water or food intake and for personal safety.

Participants will be confined at the Clinical Site for 12 hours prior to dosing to ensure compliance and for 14 hours after dosing.

Participants will be monitored for adverse events throughout the study.

Standard meals will be consumed at the Clinical Site with no additional food intake allowed. The standard meals will be consumed 4 hours and 9 hours after dosing (at approximately 12pm and 5pm). Alcohol breath testing and dipstick drugs of abuse tests will be performed upon each participant reporting to the clinical site 12 hours prior to dosing.

Screening and study exit laboratory tests will be completed to assess the health of the participants along with HIV, Hepatitis and drugs of abuse testing.

Each dose will be taken orally with 240 ml of water at ambient temperature. Medication must swallow the entire suspension and a mouth check will be conducted to ensure that the medication has been taken as directed.

Treatment: Drugs
Comparator / control treatment
The two innovator formulations administered simultaneously of 1 x 5 ml of 250 mg of N-(4-hydroxyphenyl)acetamide oral suspension and 1 x 5 ml of 100 mg of (RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension on one occasion.

Outcomes
Primary outcome [1] 328845 0
To evaluate the pharmacokinetics (as summarised by Cmax and AUC) of the test formulation relative to that of the reference formulation. All plasma samples will be assayed for N-(4-hydroxyphenyl)acetamide and (RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.
Timepoint [1] 328845 0
0 (pre-dose) and at 10 min, 20 min, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12 and 14 hours post dosing.
Secondary outcome [1] 400627 0
Time to maximum peak concentration (Tmax) will be determined by plasma sample analysis. Tmax will be the time where the maximum concentration occurred in the sample points.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All formulations will be labeled as Formulation A and B. Treatments will be allocated randomly. The identification of each treatment will only be known to the Managing Director and the Section head - Trials and Regulatory Affairs.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each participant will be identified by a 3 digit screening number and a 2 digit subject number. The screening number will be issued once the participant has given written consent to participate in the study and the two digit subject number (randomisation number) after acceptance into the study. Randomisation list will be prepared using a computer program for a two-way crossover design.
