Comparative assessment of the absorption of a generic formulation of 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine oral suspension against the innovator 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine oral tablet conducted under fasting conditions in healthy male and female volunteers.

A single dose, randomized, blinded, pharmacokinetic study of a test formulation of 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine oral suspension in a 2 way crossover comparison against the innovator 3-chloro-6-(4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine oral tablet conducted under fasting conditions in healthy male and female volunteers.

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.

Interventions

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 sup

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.
