Healthy Clinical Trial - CG-549 Tablet Pharmacokinetics Study

Status Completed

Clinical Trial Summary

This will be an open label, crossover, single dose study consisting of 2 parts (Part A and Part B) in a total of 24 healthy male and female subjects.

Clinical Trial Description

Part A Part A is an open-label, 3-period, fixed-sequence, escalating dose study in 6 healthy subjects to find a tablet dose that results in a CG-549 exposure that is expected to be safe and potentially efficacious (i.e., within the targeted efficacious exposure range as defined below). Subjects will receive the following treatments of the tablet formulation of CG-549, in the fed state: - Period 1: a single oral dose of 300 mg CG-549 on Day 1. - Period 2: a single oral dose of XX mg CG-549 on Day 1. After interim PK evaluation of Period 1, the CG-549 dose of Period 2 will aim at reaching the lower end of the targeted efficacious exposure range. - Period 3: a single oral dose of YY mg CG-549 on Day 1. After interim PK evaluation of Period 2, the CG-549 tablet dose of Period 3 will aim at reaching the higher end of the targeted efficacious exposure range. Doses XX and YY will be multiples of 300 mg and will not exceed 3 times the dose used in the preceding period. After interim PK evaluation of all periods in Part A, the CG-549 dose and the type of breakfast to be used in Part B will be selected which is anticipated to result in an exposure that is expected to be safe and potentially efficacious. Part B Part B is an open-label, 2-period, randomized crossover study in 18 healthy subjects to confirm that the selected dose of the tablet formulation of CG-549 results in a CG-549 exposure that is expected to be safe and potentially efficacious, and to compare the PK profiles of a single dose of the tablet formulation of CG 549 between the fed and the fasted states. Subjects will receive the following treatments of the tablet formulation of CG-549: - Period 1: a single oral dose of ZZ mg CG-549 on Day 1 in fed or fasted state. - Period 2: a single oral dose of ZZ mg CG-549 on Day 1 in fasted or fed state. Dose ZZ will be a multiple of 300 mg. There will be 2 treatment sequences in the study: fed-fasted and fasted-fed. Subjects will be randomly assigned to a treatment sequence in a 1:1 ratio. In the fed state, subjects will either receive a high-fat or a medium fat breakfast. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
