Official title
Genetics Informatics Trial (GIFT) of Warfarin to Prevent Deep Venous Thrombosis (DVT)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Blood clots contribute to the death of at least 100,000 Americans each year. Because many of these deaths occur suddenly where treatment is impossible, the best treatment is prevention. With this grant, researchers in Missouri, New York, Utah, Illinois, and Texas are developing strategies to improve the safety and effectiveness of clot prevention by customizing a popular blood thinner (warfarin) to each person's genetic and clinical profile. They hypothesize that the use of genetics to guide warfarin therapy will reduce the risk of venous thromboembolism (VTE) postoperatively. They further hypothesize that using a target international normalized ratio (INR) of 1.8 is non-inferior to using a target INR of 2.5 in VTE prevention.
