Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention for this trial is the test formulation of 0.25 mL of 50 mg/mL 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine oral suspension formulation.

Each dose is separated by a one week washout period.

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 24 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 urine dipstick drugs of abuse testing 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.

Outcomes
Primary outcome [1] 329217 0
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 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine tablet using one fully validated LC/MS/MS method. Validation will be conducted to comply with FDA guidelines.
Timepoint [1] 329217 0

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The subject ID will be used to randomise each participant onto the study. Allocation concealment will be completed by the pharmacy staff who are independent of subject recruitment and who are unaware of the identity of each subject.

All staff obtaining consent and confirming eligibility will remain blinded as to what formulation each subject ID has been allocated. Individual randomisation envelopes will be provided in case the identity of study drug administered to a participant needs to be known.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomization by computer
Masking / blinding
Open (masking not used)

Summary
Brief summary
The purpose of our study is to investigate the absorption, safety and tolerability of 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine. In this study we will measure how much 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine is absorbed into the bloodstream and compare the concentrations between the test and reference formulations.

This is called pharmacokinetics and refers to what happens to a medication from the time it enters the body until the exit of all traces of it.
