What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
darapladibDrug
experimental drug
| Study group | Role | What they receive |
|---|---|---|
| Single dose | Experimental | single oral dose Receives: Drug: darapladib |
| Repeat Dose | Experimental | 28 day repeat dose Receives: Drug: darapladib |
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary PK endpoints will include AUC and Cmax of darapladib and its metabolites (M10, M3 and M4) following single and repeat oral doses. Metabolite to parent AUC and Cmax ratio for each metabolite will be calculated as data permit.
Measured: following single and 28 day repeat dose
Clinical safety data (spontaneous AE reporting, vital signs, nursing/physician observation, and clinical laboratory tests) will be the primary safety endpoint.
Measured: throughout study
Secondary outcomes (2)
Secondary PK endpoints will include Tmax and T½ of darapladib and its metabolites (M10, M3 and M4) as data permit.
Measured: following single and 28 day repeat dose
Plasma Lp-PLA2 activity, expressed in terms of percent inhibition relative to baseline, as data permit.
Measured: following single and repeat dose

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing darapladib in people with Atherosclerosis, run by GlaxoSmithKline 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 8 inclusion and 19 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 16 Nov 2016. 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 PK endpoints will include AUC and Cmax of darapladib and its metabolites (M10, M3 and M4) following single and repeat oral doses. Metabolite to parent AUC and Cmax ratio for each metabolite will be calculated as data permit. (time frame: following single and 28 day repeat dose). 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 16 Nov 2016.
