Safety of Direct Oral Anticoagulant During Pregnancy — SACOD  

Thromboembolic Disease Clinical Trial

Official title: Safety of Direct Oral Anticoagulant During Pregnancy - Pregnancy, Neonatal and Infant Outcome: a National-based Study From the French Claim Database

Status Completed

Clinical Trial Summary

Pregnancy is a major risk factor of thromboembolic disease (2 to 10 increased risk of thromboembolic event for pregnant women). This risk is related to the physiological changes inducing venous stasis and hypercoagulability.

Thromboembolic disease is the first preventable cause of death during pregnancy (in France 1.1 maternal death per 100 000 living births.

The recommended treatment for pregnant women is low molecular weight heparin requiring subcutaneous injections daily. Vitamin K antagonists are contraindicated due to a teratogenic risk. Direct oral anticoagulants (DOAC) are easier to use.

Currently available preclinical and incidental exposure data on DOAC in pregnant women are very limited and insufficient to conclude on their safety. Therefore, its use during pregnancy is currently contraindicated for the grounds of precaution. The use of reimbursement data from the Système National des données de santé (National Health Data System) would provide more information on accidental exposure to DOACs during pregnancy, thanks to its completeness.

The primary objective of SACOD is to compare the prevalence of adverse perinatal outcomes in pregnant women treated with a direct oral anticoagulant versus pregnant women treated with heparin and Vitamin K antagonist.

The secondary objectives of the SACOD study are to i) determine the frequency of patients exposed to a direct oral anticoagulant during pregnancy according to pregnancy, ii) measure the prevalence of adverse perinatal outcomes in pregnant women initiating treatment with a direct oral anticoagulant therapy, iii) compare the prevalence of adverse perinatal outcomes in pregnant women initiating treatment with direct oral anticoagulants compared with pregnant women treated with heparin and a vitamin K antagonist, iv) compare the prevalence of adverse perinatal outcomes in pregnant women with Antiphospholipid syndrome treated with a direct oral anticoagulant versus pregnant women treated with heparin and anti-vitamin K, v) measure the incidence of thrombo-embolic episodes during pregnancy under anticoagulant treatment.
