Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Single dose, crossover study design whereby each participant receives the test formulation of R107 tablet on one occasion and the innovator formulation of 60 mg ketamine IV solution on one occasion with each dose separated by a one week washout period. The intervention for this trial is the test R107 formulation.

No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for 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 confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored 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 will be taken orally with 240 ml of water at ambient temperature. The R107 tablet must be swallowed whole and the IV Solution will be administered through a syringe and a mouth check will be conducted to ensure the medication has been taken as directed.

Treatment: Drugs
Comparator / control treatment
Single dose, crossover study whereby each participant receives the test formulation (1 x 60 mg) on one occasion and the innovator formulation (1 x 60 mg) on one occasion with each dose separated by a one week washout period. The comparator/control for this trial is the innovator IV solution formulation.
Control group
Active

Outcomes
Primary outcome [1] 306616 0
To evaluate the pharmacokinetics (as summarised by Cmax and AUC). All plasma samples will be assayed for ketamine and norketamine using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.
Timepoint [1] 306616 0
Sampling immediately prior to dosing and at 30 minutes and 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8, 9, 10, 12, 14, 17, 20, 24, 32 and 48 hours post dosing.
Secondary outcome [1] 349022 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.
Timepoint [1] 349022 0

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.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each participant will be given 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)
