PerMIT: Warfarin : A Prospective Randomized Controlled Trial Comparing Usual Care Warfarin Initiation to PerMIT Pharmacogenetic Guided Warfarin Therapy

Robert Pendleton·interventional·Posted Oct 12, 2009·Updated Jun 24, 2015

In Brief

A Phase 4 clinical trial evaluating warfarin pharmacogenetic dosing and Warfarin for Blood Clotting. Completed, enrolled 26 participants across 1 site.

Detailed Summary

Warfarin is the most commonly used oral anticoagulant medicine (blood thinner). Although this medicine works well, it is difficult to know how much medicine a patient needs. Many things affect how much medicine a patient needs and doses can be very different from patient to patient. It is important for patients to get the right dose to prevent clotting or bleeding problems that can happen with this medicine if the dose is too low or too high. These problems can be life-threatening. To help find the right dose, patients on warfarin must have frequent blood tests to measure how well the medicine is working. The investigators know differences in people's genes can affect how much warfarin medicine someone needs, but they don't yet know with certainty how to use this information in making patient care decisions. The hypothesis of this study is that using a patients warfarin related genetic information incorporated into a computer algorithm to be used by a warfarin provider will lead to better warfarin management compared to usual care.
