Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the test formulation of
1 x 5/2.5 mg 4,5a-epoxy14-hydroxy-3-methoxy-17-methylmorphinan-6-one hydrochloride/naloxone tablet on one occasion and the innovator formulation of 1 x 5/2.5 mg 4,5a-epoxy14-hydroxy-3-methoxy-17-methylmorphinan-6-one hydrochloride/naloxone tablet on one occasion with each dose separated by a one week washout period. The intervention for this trial is the test tablet 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 26 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. 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 be swallowed whole and a mouth check will be conducted to ensure that the medication has been taken as directed.

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 4,5a-epoxy14-hydroxy-3-methoxy-17-methylmorphinan-6-one s using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.

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. The identification of each treatment will only be known to the Managing Director and Section Head - Trials and Regulatory Affairs or their delegate.
Query!
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 study number (randomisation number) after acceptance into the study. Randomization will be performed using a randomisation table created by computer software (i.e. computerized sequence generation).
