About this study

Official title: CG-549 Tablet Pharmacokinetics Study: An Open-label, Single Ascending Dose Study to Evaluate the Safety and Pharmacokinetics of a Tablet Formulation of CG-549 in Healthy Subjects

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.

Read the detailed 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CG-549 in people with Healthy, run by CrystalGenomics, Inc. at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Observed Plasma Concentration (Cmax) of CG549 (time frame: up to 4 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 May 2022.
