Health condition
Health condition(s) or problem(s) studied:
Bioequivalence study conducted in healthy volunteers comparing two formulations of desvenlafaxine 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, desvenlafaxine belongs to a class of medicines called Serotonin-Nonadrenaline Reuptake Inhibitors and is an antidepressant prescribed for the treatment and prevention of relapse of depression. 295786 0

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover over study design whereby each participant receives the test formulation of desvenlafaxine (1 x 100 mg) on one occasion and the innovator formulation of desvenlafaxine (1 x 100 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of desvenlafaxine.

Each dose (1 x 100 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 10 hours before receiving each dose and to fast for 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 10 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 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 healthy of participants along with HIV, Hepatitis and drugs of abuse testing.

Comparator / control treatment
Single dose, crossover over study design whereby each participant receives the test formulation of desvenlafaxine (1 x 100 mg) on one occasion and the innovator formulation of desvenlafaxine (1 x 100 mg) on one occasion with each dose seperated by a one week washout period. The comparator/control for this trial is the innovator formulation of desvenlafaxine.

Outcomes
Primary outcome [1] 295723 0
To compare the bioavailability of desvenlafaxine (as summarised by Cmax and AUC) for the two formulations. All plasma samples will be assayed for desvenlafaxine using a fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines.

Secondary outcome [1] 316339 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 desvenlafaxine 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 - Trials and Regulatory Affairs. Randomisation will be performed using a randomisation table created by computer software (i.e. computerised sequence generator).
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
Masking / blinding
