Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Mutliple dose, crossover study design whereby each participant receives the test formulation of 1,1-Dimethyl-2-Phenylethylamine oral tablet (1 x 40 mg) on five occasions and the innovator formulation of 1,1-Dimethyl-2-Phenylethylamine oral capsule (1 x 40 mg) on five occasions with each dose separated by a 10 day washout period. The intervention for this trial is the test tablet formulation.

On study days 1-5 subjects will receive 5 daily doses of one formulation (either the test or innovator) and on study days 15-19 they will receive 5 daily doses of the other formulation (either the innovator or test).

Each dose (1 x 40 mg) 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 the medication has been taken as directed.

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

Participants are required not to eat for 4 hours before receiving each dose on study days 1 to 4 and 15 to 18.

On study days 1 and 15 subjects will report to the Zenith Clinical Site for dosing and observation of adverse events and the provision of one blood sample. They are required to stay at the clinical site for 24 hours after dosing.

On study days 2 to 4 and 16 to 18 subjects will report to Zenith Technology for dosing and the provision of one blood sample.

On study day 5 and 19 no water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose) and subjects are required to fast for 8 hours prior to receiving the dose and approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 8 hours prior to dosing to ensure compliance can be monitored and for 24 hours after dosing.

Standard meals will be consumed at the Clinical Site on study days 5 and 19 with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site prior to dosing.

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

Comparator / control treatment
Multiple dose, crossover study design whereby each participant receives the test formulation of 1,1-Dimethyl-2-Phenylethylamine tablet (1 x 40 mg) on five occasions and the innovator formulation of 1,1-Dimethyl-2-Phenylethylamine capsule (1 x 40 mg) on five occasions with each dose separated by a 10 day washout period. The comparator/control for this trial is the innovator capsule formulation.

Outcomes
Primary outcome [1] 305380 0
To compare the bioavailability of 1,1-Dimethyl-2-Phenylethylamine (as summarised by Cmax(ss) and AUC(ss)) for the two formulations. All plasma samples will be assayed for 1,1-Dimethyl-2-Phenylethylamine using a fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.
Timepoint [1] 305380 0
0, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16, 20 and 24 hours post dosing
Secondary outcome [1] 345018 0
Time to maximum peak concentration (Tmax). Tmax will be the time where the maximum concentration occurred in the sample points. All plasma samples will be assayed for 1,1-Dimethyl-2-Phenylethylamine using a fully validated LC/MS/MS method.

Study design
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 labelled as Formulation A and B. The identification of each treatment will only be known to the Managing Director and the Section Head - Trails and Regulatory Affairs.

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. Sequence generation will be by using a simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation list will be prepared using a computer program for a balanced two-way crossover design.
