Filter by:The study objective is to evaluate the efficacy and safety of oral YM150 for 52 weeks in patients with a history of venous thromboembolism.
The purpose of this study is to determine whether DNA analysis improves the efficiency of dosing and safety in patients who are being started on warfarin therapy.Warfarin, a blood thinner (anticoagulant) prescribed to 1-2 million patients in the United States, is a leading cause of drug-related adverse events (e.g., severe bleeding), in large part due to dramatic (20-fold) differences between individuals in dose requirements. At least half of this variability now can be explained by 3 common genetic variants, age, body size, and sex; however, warfarin therapy continues to begin with the same dose in every patient with the correct individual dose determined by trial and error. This study proposes to determine genetic variations the same day from DNA simply obtained by swabbing the inside of the cheek and use this information to determine the proper dose regimen individually in each patient. The aim is to show that the investigators can achieve more rapid, efficient, and safe dosing in up to 500-1000 individuals who are initiating warfarin therapy for various clotting disorders across a large healthcare system in order to demonstrate improved dosing effectiveness, efficiency, and safety with genetic-based dosing, which could lead to a nationwide application resulting in as much as a $1 billion dollar annual benefit in healthcare outcomes.
The purpose of this study is to examine the superiority of YM150 to the placebo and to evaluate the dose-dependent response of YM150 in patients undergoing elective total knee replacement surgery.
The purpose of this study is to examine the superiority of YM150 to the placebo and to evaluate the dose-dependent response of YM150 in patients undergoing elective total hip replacement surgery.
Patients that are on total knee/hip replacement initiate prophylaxis treatment on the hospital ground. Once they leave the hospital, as outpatients they continue with the treatment at least during two consecutive weeks. Patients will be instructed to follow treatment recommendations (either LMWH or oral treatment, at physician discretion) and to come back to the surgeon after that period. At that visit, the Treatment Satisfaction Questionaire with Medication (TSQM) test as well as the Moriski-Green Questionaire (measures compliance with medication) will be answer by the patient. TSQM is an self administered validated scale (validated also in spanish) that measures in a generic way the treatment satisfaction to a treatment. Morinski-Green test will be used to measure the compliance degree on medication.
The purpose of this study is to evaluate the efficacy and safety of various doses of YM150 (the experimental drug) compared to enoxaparin in the prevention of venous thromboembolism in patients that are undergoing elective hip replacement surgery.
Enoxaparin is a type of low molecular weight heparin (LMWH), or anticoagulant, used to prevent and treat blood clots. Formation of blood clots, or venous thromboemboli (VTE) in pregnancy can have dangerous and even life-threatening effects on the mother and fetus. Enoxaparin is the preferred medicine to prevent clotting in pregnant patients who are at risk for VTE, because it has been studied to be safe and effective in pregnancy without any harms to the fetus. Although this medication is routinely used and is recommended by several prominent medical groups, the optimal dosing for prevention of VTE is still unclear. The range of standardly prescribed dosing regimens of Enoxaparin includes 40mg daily and 1mg/kg daily, but these two dosing strategies have never been compared in a head to head fashion.
Brigham and Women's Hospital will coordinate a Quality Improvement Initiative at other hospitals that focuses on whether physician notification prior to discharge of high risk VTE patients will reduce the incidence of VTE after hospital discharge.
The purpose of this study is to evaluate the safety and efficacy of therapeutic anticoagulation with tinzaparin during pregnancy via weight-based dosing.
