About this study

Official title: Dabigatran Versus Rivaroxaban in Cerebral Venous Thrombosis, a Randomized Controlled Trial

Along with the current clinical trial, the efficacy and safety of a 150 mg Bid dabigatran administered within 24 hours of randomization after having first-ever cerebral venous thrombosis compared to 20 mg rivaroxaban were assessed through rate of recurrent VTE, mRS, rate of venous recanalization, HIT score, MoCA test, and central and peripheral hemorrhagic complications

Read the detailed description

The investigators conducted a single-blinded randomized controlled trial between August 2024 and September 2026 after the ethics committee of the faculty of medicine at Kafr el-Sheik University approved it.

The investigators got written informed consent from all eligible patients or their first order of kin before randomization.

The study will be composed of 2 arms rivaroxaban arm, which consisted of 100 patients who received 150 mg Bid dabigatran for 6 months, and the rivaroxaban arm, consisting of 100 patients who received 20mg rivaroxaban daily for 6 months

Study Procedures:

Every patient in our study will undergo:

Clinical workup: History, clinical assessment, NIHSS, MoCA, HIT-6, and mRS were recorded at baseline and at 30,90,180 days as a follow-up.

Detection of Risk Factors \& Profiles:

Echocardiography TTE: in indicated patients ECG Monitoring: daily ECG monitoring will be performed in indicated patients. 3- Carotid Duplex: carotid duplex in indicated patients.

4- ESR \& Lipid Profile\& liver functions: All will be tested routinely for all patients.

5- Non-contrast CT brain and CTV on admission or MRI and MRV:, at baseline and after 6 months of treatment CT brain: Any patient with unexplained clinical deterioration at any time throughout his/her hospital stay will be urgently imaged by CT.

Primary End Point:

The primary efficacy outcome was the rate of Proportion of subjects with partial or complete venous recanalization by Day 180, and the primary safety outcome was the rate of drug hemorrhagic complications using the PLATO bleeding definition.

  • Secondary End Point: The secondary efficacy outcomes were to evaluate the rates of patients who achieved a favorable outcome with (mRS = 0-2) after one week and after 180 days in a face-to-face interview in the outpatient clinic, Proportion of subjects with recurrent venous thromboembolism (any thrombosis at a new site, including cerebral venous thrombosis in a separate location from the index event) at Day 180 or the end of anticoagulation, whichever is sooner, rates of a composite of pulmonary embolism, DVT, myocardial infarction, and death due to vascular events after 180 days of follow-up, the MoCA, HIT-6 by 180 days, while the secondary safety outcome was the rate of treatment-related adverse effects assessed by a follow-up questionnaire

What is being measured

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

  1. The proportion of subjects who have partial or complete venous recanalization by Day 180

    the investigators will perform magnetic resonance venography for all patients after 6 months to show if there is partial or complete recanalization of the affected venous sinus

    Measured: 180 days

  2. Rate of drug-related hemorrhagic complications

    the rate of drug hemorrhagic complications which was evaluated using the PLATO bleeding definition which classified hemorrhagic complications into three types as follows: Major bleeding which had one or more of the following criteria: fatal bleeding, intracranial, intrapericardial, bleeding associated with reduction of hemoglobin > 3-5 g/dl, bleeding required transfusion of two to four units whole blood or PRBCs, bleeding produced hypovolemic shock or severe hypotension that required pressor or surgery; Minor bleeding that required medical intervention to stop or treat bleeding: Minimal bleeding: any bleeding that did not require intervention or treatment such as bruising, bleeding gums, oozing from injection sites.

    Measured: 180 days

Secondary outcomes (5)
  1. value of Modified Rankin Scale (mRS) at six months

    mRS measures the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. Its value ranges from 0 to 6; the lower the score, the better the stroke outcome. A favorable stroke outcome is considered with an mRS value equal to two or less.

    Measured: 6 months

  2. value of HIT-6 score in each group after six months of treatment

    The investigators assessed the absolute change in HIT6 score, the Headache Impact Test-6 (HIT-6) assessed the burden of headache in each group; the HIT-6 consists of six items: pain, social functioning, role functioning, vitality, cognitive functioning, and psychological distress, the patient answers each of the six related questions using one of the following five responses: "never", "rarely", "sometimes", "very often," or "always." These responses are summed to produce a total HIT-6 score that ranges from 36 to 78, where a higher score indicates a greater impact of headache on the daily life of the respondent. It has four impact grades: little-to-no impact (HIT-6 score: 36-49), moderate impact (HIT-6 score: 50-55), substantial impact (HIT-6 score: 56-59), and severe impact (HIT-6 score: 60-78)

    Measured: 6 months

  3. rate of drug adverse effects

    Drug adverse effects: all non-hemorrhagic side effects related to the drugs of our study will be reported

    Measured: 6 months

  4. The proportion of participants with recurrent venous thromboembolism

    The investigators will assess the proportion of participants with recurrent venous thromboembolism (any thrombosis at a new site, including CVT in a separate location from the index event) during 6 months of treatment

    Measured: 6 months

  5. rate of composite pulmonary embolism, myocardial infarction, and death due to vascular events

    The investigators will assess the proportion of participants with pulmonary embolism, myocardial infarction, and death due to vascular events at during 6 months of treatment

    Measured: 6 months

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 10 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: looking for participants now, as of the sponsor's last update on 13 Aug 2024. 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 Egypt. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact mohamed G. Zeinhom, MD (2001009606828, mohamed_gomaa@med.kfs.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The proportion of subjects who have partial or complete venous recanalization by Day 180 (time frame: 180 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06551402, which also lists 2 linked publications.

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?
