About this study
Official title: Postmarketing Study of ORTHO EVRA and Levonorgestrel Oral Contraceptives in Relation to Non-fatal Venous Thromboembolism, Ischemic Stroke and Myocardial Infarction.
This study uses the PharMetrics and MarketScan US health care insurance claims database to estimate relative risks for non-fatal venous thromboembolism (including cerebral venous sinus thrombosis), ischemic stroke, and acute myocardial infarction (heart attack), in current users of ORTHO EVRA (norelgestromin and ethinyl estradiol contraceptive patch) compared to current users of oral levonorgestrel-containing oral contraceptives with 30 micrograms ethinyl estradiol, with special attention to duration of use.
Read the detailed description
This observational, retrospective study uses the PharMetrics and MarketScan US health care claim insurance database to assess the occurrence of venous thromboembolism (including cerebral venous sinus thrombosis), ischemic stroke, and acute myocardial infarction in current users of ORTHO EVRA (norelgestromin and ethinyl estradiol transdermal contraceptive patch) compared to current users of levonorgestrel-containing oral contraceptives with 30 micrograms ethinyl estradiol, with special attention to duration of use. PharMetrics is a United States based, ongoing longitudinal database with information on around 55 million covered lives going back as far as 1995. It is made up of data contributed by managed care plans throughout the United States and it contains information on paid claims for pharmaceuticals, medical diagnoses and procedures as well as demographic information on all subjects. There will be 3 sets of cases reflecting women who have a first-time recorded claim for an ICD-9 diagnosis of the following during the study period: (1) deep vein thrombosis (blood clot), pulmonary embolism, or cerebral venous sinus thrombosis, venous thrombotic event (VTE) with hospitalization, a visit to the emergency room or positive indication of VTE from diagnostic test results, at any time during the study period and who had subsequent multiple claims for anticoagulant treatment. The requirement for multiple prescriptions for anticoagulation therapy was used to provide evidence that the original diagnosis of VTE was confirmed. (2) ischemic stroke and who were hospitalized, or (3) acute myocardial infarction (heart attack) or acute coronary revascularization and who were hospitalized. Three separate sets of controls will be identified for each outcome. Planned analysis will estimate the relative risk of idiopathic (unknown cause) ischemic stroke or myocardial infarction, and another analysis will estimate the relative risk of idiopathic VTE. Conditional logistic regression will be used. Analyses will be stratified by calendar year. The analyses will be repeated including non-idiopathic cases of VTE, ischemic stroke, and acute myocardial infarction. Each transdermal patch containing 6 milligrams norelgestromin and 0.75 milligram ethinyl estradiol is worn for 1 week for 3 consecutive weeks; the fourth week is patch-free. Triphasic levonorgestrel-containing oral contraceptives with 30 micrograms ethinyl estradiol is taken for 21 consecutive days followed by no pill or an inert pill for 7 days. Duration of use can vary. NOTE: The study was conducted in two parts. This study, CR014383, represents the first portion of the study. Study CR012022, NCT00377988, represents the second portion of the extended study.

It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
