About this study
Official title: EXPERT Trial: Exercise to Prevent Post-thrombotic Syndrome Elicited by Recent Thrombosis
The purpose of this pilot study is to assess the feasibility of determining the effects of a structured exercise program started two to four weeks after diagnosis of a first episode lower-extremity deep vein thrombosis (DVT) for a period of 12 weeks in reducing the incidence of post-thrombotic syndrome (PTS).
Read the detailed description
Deep Vein Thrombosis (DVT) affects nearly 300,000 people in the U.S. each year. DVT of the leg results in PTS in up to 65% of patients,despite receiving appropriate medical management with anticoagulant therapy.
PTS, caused by persistent venous outflow obstruction and venous valvular dysfunction, may result in symptoms of leg pain, swelling, heaviness and cramping especially with prolonged standing.
All eligible patients with documented first-episode DVT interested in participating will undergo medical screening and a screening treadmill test prior to enrollment between two and four weeks post DVT diagnosis. All patients will be provided and asked to wear class II (30 to 40mmHg) knee length compression hose daily during the entire trial.
The formal exercise training includes both a supervised walking program and a home-based walking program for 12 weeks with follow-up at 26 weeks. Blood tests will be taken to measure levels of indicators of inflammation at baseline, week 4, week 12, and week 26. The primary outcomes will be the feasibility of the exercise program and the incidence of post-thrombotic syndrome at 26 weeks.

The record says: finished, as of the sponsor's last update on 13 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Villalta PTS score (time frame: at 26 weeks). 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?
