About this study

In patients with acute clots (deep vein thrombosis or pulmonary embolism) the investigators will collect real world data on their short and long term outcomes. The investigators hypothesise that in patients treated from the outset with rivaroxaban that: 1. treatment will be non-inferior to treatment with conventional anticoagulants (heparins and warfarin); 2. there will be less bleeding than when patients are on conventional anticoagulants; 3. there will be a lower long-term incidence of morbidity from chronic thromboembolic pulmonary hypertension and post-thrombotic limb syndrome.

Read the detailed description

United Kingdom-only prospective, non-interventional, investigator-led, multi-centre, single cohort, registry. The observation period for each patient covers the treatment period with rivaroxaban and follow up until study end. For each patient, the treating health care professional records patient demographics, medical history, signs and symptoms, diagnosis, treatment and safety parameters at an initial visit and subsequent follow-up visit(s). Data monitoring will be undertaken by the Sponsor.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of long term complications

    Incidence of long term complications as composite primary end point of VTE recurrence, PTS and CTEPH in patients treated with rivaroxaban without bridging heparin therapy

    Measured: 5 years from diagnosis of index event (DVT or PE), annual follow-up

Secondary outcomes (7)
  1. Incidence of major post-thrombotic complications

    Incidence (up to 5 years) of individual major sequelae (VTE recurrence, PTS and CTEPH)

    Measured: 5 years from diagnosis of index event (DVT or PE), annual follow-up

  2. Incidence of treatment-emergent bleeding rates

    Long-term treatment-emergent bleeding rates (up to 5 years).

    Measured: 5 years from diagnosis of index event (DVT or PE), annual follow-up

  3. All-cause mortality

    Measured: 5 years from diagnosis of index event (DVT or PE), annual follow-up

  4. Treatment adherence

    Adherence will be measured by patient interviews with a validated questionnaire conducted during follow-up visits.

    Measured: Full duration of anticoagulation treatment (average of 6 months)

  5. Quality of life assessment

    Regular quality of life assessment in patients diagnosed with VTE, three questionnaires to be completed at time of index event, then at second and then final clinic visits.

    Measured: Full duration of anticoagulation treatment (average of 6 months)

  6. Healthcare resource utilisation

    Healthcare resource utilisation in patients treated with long-term (>12 months) anticoagulation

    Measured: Full duration of anticoagulation treatment (average of 6 months)

  7. Incidence of other thromboembolic events

    Long-term incidence rates of other thromboembolic events (e.g. myocardial infarction and ischaemic stroke).

    Measured: 5 years from diagnosis of index event (DVT or PE), annual follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of Venous Thromboembolism, run by King's College Hospital NHS Trust at 4 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United Kingdom. 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?

Incidence of long term complications (time frame: 5 years from diagnosis of index event (DVT or PE), annual follow-up). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2020.
