Lovaza's Effect on Clopidogrel in a Neuro Population


Phase 0 Results N/A

Trial Description

In patients who have suffered an ischemic stroke or TIA (mini-stroke), as well as in patients who are candidates for neuroendovascular stenting, it is standard of care to treat these patients with antiplatelet therapy, or "blood-thinners", the most common of which is clopidogrel (Plavix) with or without the addition of aspirin. A relatively common problem encountered with these patients is non-responsiveness to clopidogrel therapy. A prior study in cardiac patients showed that the addition of omega-3 polyunsaturated fatty acids (Lovaza, or "fish oil") can increase a patient's response to therapy with clopidogrel, but there have been no studies in neuro patients. In this study, patients will be divided into one of two groups: in the study arm, patients will receive clopidogrel +/- aspirin as well as Lovaza. In the control arm, patients will only receive clopidogrel +/- aspirin. Assays will be done to measure responsiveness to clopdiogrel on days 0, 12-24 hours after loading dose, day 3-5 if still inpatient, and at a follow-up visit 20-30 days after the start of the study. The investigators believe that this study will show an increase in platelet aggregation in patients receiving both clopidogrel and Lovaza.
