Treatment of Reperfusion Event by Vitamin C Infusion (TREVI)

March 8, 2016 updated by: Francesco Violi, University of Roma La Sapienza

Effect of Vitamin C Infusion on Coronary Reperfusion Indexes

Primary Hypothesis: Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, assessed by measurements of cardiac biomarkers, during acute myocardial infarction.

Secondary Hypotheses: Prophylactic Vitamin C Intravenous Infusion at the time of percutaneous coronary intervention (PCI) would limit the size of the infarct, as measured by the area of delayed hyperenhancement that was seen on cardiac magnetic resonance imaging (MRI), assessed on day 5 after infarction, during acute myocardial infarction.

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multicenter, prospective, controlled, randomized study that will be conducted at up to 5 centers in Italy. All patients who meet the eligibility criteria will be randomized to receive during surgical procedure an intravenous infusion of Vitamin C or Placebo.

Patients will have repeat clinical follow-up to 5 days, 3 and 6 months and 1 year.

The new angiography evaluation will be done if necessary. The study population will consist of at least 100 patients who presented within 12 hours after the onset of chest pain, who had ST-segment elevation of more than 0.1 mV in two contiguous leads, and for whom the clinical decision was made to treat with percutaneous coronary intervention (PCI). Following confirmation of eligibility criteria, patients will be randomized in a 1:1 ratio to receive prophylactic infusion of Vitamin C or Placebo. The coronary angiograms will be assessed at a core laboratory with Quantitative Coronary Angiography.

The incidence of clinical events, including death, myocardial infarction, target vessel revascularization, stent thrombosis, will be evaluated at 1, 3, 6 and, 12 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers
