Atorvastatin and Clopidogrel HIgh DOse in Stable Patients With Residual High Platelet Activity
A Phase 4 study testing atorvastatin and clopidogrel and Clopidogrel in people with Stable Angina, run by Ospedale Misericordia e Dolce at 1 site in Italy.
Trial summary
The purpose of this study is to evaluate if high-dose (80mg/day) atorvastatin might exert an adjunctive anti-platelet effect compared to high-dose clopidogrel (150mg/day) in stable patients with high on-treatment reactivity according to a point-of-care platelet function assay.

About this study
The purpose of this study is to evaluate if high-dose (80mg/day) atorvastatin might exert an adjunctive anti-platelet effect compared to high-dose clopidogrel (150mg/day) in stable patients with high on-treatment reactivity according to a point-of-care platelet function assay.
Read the detailed description
This is a prospective, randomized, open-label, control-active trial performed in elective patients candidates to coronary drug eluting stent implantation who presented high-on-treatment platelet reactivity, immediately before coronary intervention (PCI). All patients are treated with aspirin (100 mg/day) and standard-dose clopidogrel (600 mg as loading dose and 75 mg daily as maintenance dose)for at least 7 days before PCI. Platelet function is assessed by the VerifyNow P2Y12 assay (Accumetrics, San Diego, CA). Patients are eligible to be enrolled if they have high-on-treatment reactivity defined as P2Y12 reaction units (PRU) >= 230, immediately before PCI. After PCI, patients are randomized to receive high-dose clopidogrel (150 mg daily) or high-dose atorvastatin (80mg/day) + high-dose clopidogrel (150 mg daily). Study visits and platelet function testing with the VerifyNow P2Y12 test are conducted at 7 and 30 days after randomization.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in on-treatment platelet reactivity at 7 and 30 days
Pharmacodynamic analysis of the randomized groups includes a) assessment of the absolute level of on-treatment reactivity, b) change in on-treatment reactivity, c) rate of high on-treatment reactivity at 7 and 30 days. The platelet reactivity is measured with the VerifyNow P2Y12 test (Accumetrics, SanDiego, CA).
Measured: pre-PCI, 7 days and 30 days

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing atorvastatin and clopidogrel and Clopidogrel in people with Stable Angina, run by Ospedale Misericordia e Dolce at 1 site in Italy.
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 3 inclusion and 8 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 Jan 2012. 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 Italy. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Change from baseline in on-treatment platelet reactivity at 7 and 30 days (time frame: pre-PCI, 7 days and 30 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01335048, which also lists 1 linked publication.
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 Jan 2012; AzTrials last refreshed its copy on 7 Nov 2026.
