About this study

Official title: A Phase I, Open-Label, Randomized, Multiple-Dose, Two-Way Crossover Study of the Pharmacodynamics of CGT 2168 Compared With Plavix®

CG106 is a Phase I open-label, randomized, multiple-dose, two-way crossover study to characterize the pharmacodynamics and pharmacokinetics of the investigational fixed-dose combination product CGT 2168 (clopidogrel, 75 mg and omeprazole, 20 mg) relative to Plavix® (clopidogrel, 75 mg).

Healthy volunteer subjects will undergo two dosing periods. In each 7-day dosing period, subjects will receive oral doses of study drug consisting of open-label CGT 2168 or Plavix® in the order determined by the randomization schedule. Each period of dose administration will be separated by a two-week washout period. Study exit will occur 1 week after Dosing Period 2. The expected total duration of participation is 8 weeks (56 days), including a screening visit on or within 21 days prior to enrollment.

On the day before Day 1 and Day 7 in each dosing period, subjects will be admitted to the Phase I unit. Blood samples to determine ADP-induced platelet aggregation will be collected pre-dose on Day 1 and 2 h after dosing on Day 7. Plasma concentrations of clopidogrel parent and clopidogrel carboxylic acid metabolite will also be measured pre-dose on Day 1 and pre-dose and serially after dosing on Day 7.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary endpoint of this study is inhibition of platelet aggregation (IPA) based on maximum platelet aggregation (MPA) to 5 and 20 µM ADP after 7 days daily dosing with CGT-2168 compared to Plavix®.

    Measured: 7 days

Secondary outcomes (2)
  1. Residual aggregation, measured 10 min after the addition of 20 and 5 µM ADP, after 7 days daily dosing with CGT 2168 compared to Plavix®.

    Measured: 7 days

  2. Plasma PK measures of clopidogrel (parent drug and carboxylic acid metabolite) with CGT 2168 compared to Plavix®.

    Measured: 7 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CGT-2168 and Plavix in people with Healthy, run by Cogentus Pharmaceuticals at 1 site in United States.

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 5 inclusion and 14 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 Aug 2008. 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 United States. 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?

The primary endpoint of this study is inhibition of platelet aggregation (IPA) based on maximum platelet aggregation (MPA) to 5 and 20 µM ADP after 7 days daily dosing with CGT-2168 compared to Plavix®. (time frame: 7 days). 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 Aug 2008.
