Six Years of Follow-up After Idiopathic Venous Throbmoembolism

France409 participantsStarted 2013-03-28

Plain-language summary

Beyond the first 6 months of anticoagulation, patients with a first episode of unprovoked venous thromboembolism have a high risk of recurrence after stopping anticoagulations. Extending anticoagulant therapy for an additional 18 months is associated with a major reduction of recurrent VTE; however this benefit tended to be lost after stopping anticoagulation during a follow-up period of two years. This risk of recurrentce is likely to continuously increase over the years as well as the risk of chronic thromboembolic pulmonary hypertension (after pulmonary embolism) or the risk of post-thrombotic syndrome (after deep vein thrombosis). The aim of the PADIS-EXTENSION trial is to estimate these risks over 6 years of follow-up in patients who have been initially treated during 6 months or 24 months (patients included in the PADIS PE and PADIS DVT trial).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
