Fondaparinux is an anticoagulant used in the prevention and treatment of thromboembolic disease. It has recently been approved in the European Union (EU) for the treatment of patients with isolated superficial vein thrombosis (SVT), i.e. without concomitant deep vein thrombosis (DVT), of the lower limbs. As part of EU approval, GlaxoSmithKline (GSK) committed to evaluate physicians' adherence to fondaparinux prescribing information regarding proper diagnosis and dosing for the treatment of SVT. The primary objective is to evaluate physicians' adherence to fondaparinux prescribing information for the treatment of patients with SVT without concomitant DVT. The study is designed as a non-interventional, retrospective chart review of patients prescribed fondaparinux to treat their SVT. The study will be conducted in several EU countries.

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common post-operative complication. The effectiveness of fondaparinux compared with other injectable anticoagulants in VTE following major orthopedic and abdominal surgery has been evaluated in database studies; however, the effectiveness of injectable anticoagulant medications following cancer-related surgeries in the practice setting has not been as well documented. The objective of this study is to analyze patient records from a national hospital database and compare the outcomes and costs between four types of injectable anticoagulant medications that were prescribed for the prevention of VTE following cancer-related surgery. This analysis will assess and quantify the outcomes, resource utilization, and cost of care for patients receiving fondaparinux, enoxaparin, dalteparin or unfractionated heparin. The outcomes of interest include the occurence of VTE, rates of major bleeds, medical resource utilization, and total costs (medical plus pharmacy). The source of data for this study is the Premier Perspective Database™. This hospital claims database links de-identified inpatient medical, pharmacy, and billing data from more than 500 hospitals. This study is a retrospective cohort study that uses propensity score matching to adjust for the differences between the numbers of patients treated with each medication.
Arixtra (fondaparinux sodium) was the first selective Factor Xa inhibitor to be marketed. As with all anticoagulants, an important adverse event associated with Arixtra use is haemorrhage. Previous studies using clinical trial and observational data show no difference in the risk of haemorrhage in patients treated with Arixtra compared to (low molecular weight heparins) LMWHs. This study will assess the risk of haemorrhage in major orthopaedic surgery patients (hip fracture surgery and/or hip/knee replacement surgery) treated with either Arixtra or LMWH for thromboprophylaxis and will provide additional observational data from a European country to strengthen the comprehensive review of haemorrhage and the post-marketing safety of Arixtra. All patients age 18 years and older with a primary discharge diagnosis for hip fracture surgery and/or a hospitalization for hip and/or knee replacement surgery from the PHARMO RLS database in the Netherlands are eligible for participation. For study inclusion patients must receive either Arixtra or LMWH as initial in-hospital thromboprophylactic agent and have at least three months in the PHARMO RLS database before cohort entry date. Patients with a history of hospitalization for haemorrhage, renal failure or liver failure in the past 3 months will be excluded. Descriptive statistics, including gender, age, length of treatment, co-morbidities, concomitant medications, and other covariates will be calculated. Data for this study were obtained from different registers in the PHARMO medical record linkage system (PHARMO RLS) in the Netherlands. The PHARMO medical record linkage system is a population-based patient-centric data tracking system that includes high quality and complete information of patient demographics, drug dispensing, and hospital morbidity records of approximately 2.3 million community-dwelling inhabitants of 48 geo-demographic areas in the Netherlands. The PHARMO registers are linked on a patient level and contain unprecedented accurate and complete information required for the study. The out patient database contains drug dispensing data in the U-Expo database are encoded according to standards based upon the Z-Index drug database (www.z-index.nl). Therefore, it is possible to identify and classify drug use in time, both on the basis of national and international classification schemes as well as on the basis of individual active ingredients and administration forms. Of each dispensed drug, the Anatomical Therapeutic Chemical (ATC) code, the dispensing date, the prescriber, the prescribed dosage regimen, the dispensed quantity, the cost and the estimated legend duration of use are available. The hospital pharmacy database comprises hospital pharmacy data collected in a growing number of non-academic hospitals in the Netherlands. Currently, data are collected on patient level for more than one million patients from a representative sample of non-academic hospital pharmacies scattered over the Netherlands. The hospital pharmacy database includes data on in-patient medication orders such as type of drug, dose, and time of administration and duration of use. The Dutch Medical Register (LMR) is the data source comprising all hospital admissions in the Netherlands (www.prismant.nl). These records include detailed information concerning the primary and secondary discharge diagnoses, diagnostic, surgical and treatment procedures, type and frequency of consultations with medical specialists and dates of hospital admission and discharge. All diagnoses are coded according to the International Classification of Diseases, 9th edition (ICD-9-CM). Currently, data until December 2008 are available.
The primary objective of this study is to evaluate the efficacy (as measured by the rate of recurrent symptomatic Venous Thromboembolism [VTE] (i.e., Pulmonary thromboembolism [PE] and Deep Vein Thrombosis [DVT])) and safety of GSK576428 as the initial treatment in subjects with acute symptomatic DVT in an open-label design.
The purpose of this study is to evaluate the efficacy and safety of fondaparinux in comparison with a heparin (nadroparin) in preventing deep vein thrombosis (blood clots in the leg veins), whether symptomatic or detected by ultrasound, and pulmonary embolism (blood clots that migrate to the lungs) in patients with leg injuries below the knee that require a cast or other type of immobilization but not surgery.
To evaluate fondaparinux 2.5mg subcutaneously once daily for 45 days in the treatment of acute (recent) superficial thrombophlebitis.
This study is requested by PMDA to confirm the optimal dose for THR (total hip replacement).
This study will evaluate the effects of nadroparin on survival and disease progression in patients with hormone-refractory prostate cancer (HRPC), locally advanced pancreatic cancer or non-small-cell lung carcinoma (NSCLC).
