Health condition
Health condition(s) or problem(s) studied:
Bioequivalence study conducted in healthy volunteers comparing two formulations of melatonin with no health condition or problem studied.
Although this study is being conducted in healthy volunteers who are not being treated for the condition to which the medicine is used, melatonin is a naturally occurring hormone produced by the pineal gland and is indicated as monotherapy for the short term treatment of primary insomnia characterised by poor quality of sleep in patients who are aged 55 or over.

Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the test formulation of melatonin (1 x 2 mg) on one occasion and the innovator formulation of melatonin (1 x 2 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of melatonin.
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 10 hours before receiving each dose and to fast for approximately 4 hours after receiving a standardized breakfast and 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 10 hours prior to dosing to ensure compliance and will be monitored and for 24 hours after dosing.
Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours 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.
Each dose (1 x 2 mg) will be taken orally with 240 ml of water at ambient temperature immediately after consuming a high fat content breakfast. Medication must be swallowed whole and a mouth check will be conducted to ensure the medication has been taken as directed.

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 - Trials 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
