Thromboprophylaxis With Rivaroxaban In Patients With Malignancy and Central Venous Lines (TRIM-Line)

January 18, 2024 updated by: Ottawa Hospital Research Institute

A Pilot Study Assessing the Feasibility of a Randomized Controlled Trial Investigating Primary Thromboprophylaxis With Rivaroxaban in Patients With Malignancy and Central Venous Catheters

Purpose of the Pilot Trial:

To determine the feasibility of conducting a multicentre randomized open label controlled trial evaluating the use of prophylactic dose rivaroxaban to prevent central venous catheter (CVC) associated venous thromboembolism (VTE) among cancer patients.

Hypothesis: treatment with low dose rivaroxaban (10mg) will reduce the incidence of upper extremity venous thrombosis in a high risk population with cancer and CVC.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Design:

This is a pilot interventional study to be conducted at 2 Canadian Centres. The Ottawa Hospital and Juravinski Hospital. It is an open label randomized controlled trial.

Consenting participants, meeting eligibility criteria will be randomized at the time of enrollment to one of two groups.

Rivaroxaban 10mg by mouth daily x 90 (+/- 3) days OR Standard of Care

Participants in the treatment arm will have study drug dispensed at Day 1 and take medication for 90 days or until CVC is removed. Follow up visits (in person or phone) will occur at Day 30 (+/- 3 days) and Day 90 (+/- 3 days). Overall, participants will be followed for 3 months. Adverse events will be collected for the first 90 days.

Outcomes The primary feasibility outcome for the pilot study is the number of participants recruited per centre per month. We will obtain baseline details of the patient's type, location and treatment of cancer, comorbidities and medications. Secondary feasibility outcomes of the pilot study will include, consent rates, loss to follow up, adherence to therapy defining 80% or greater medication taken as having good adherence to study drug, proportion of screened patients who meet eligibility criteria.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame
Primary Feasibility Outcome - Number of Participants Recruited Per Month
Time Frame: 12 months
A convenience sample size of 100 patients was chosen to allow reporting of the average monthly recruitment.

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Thrombotic Complication
Time Frame: 90 days
Thrombotic complication was defined as a combination of major venous thromboembolism (VTE); any symptomatic or incidentally detected proximal deep vein thrombosis (DVT) of the lower or upper limbs, any nonfatal symptomatic or incidental pulmonary embolism (PE), and pulmonary embolism-related death) and any other deep (ie, distal, splanchnic, or cerebral) or superficial venous thrombosis.
90 days
Number of Participants With CVC-Related Complication
Time Frame: 90 days
Central venous catheter (CVC) occlusion was defined as an obstruction of the CVC lumen that prevents or limits the ability to flush, withdraw blood, and/or administer solutions or medications
90 days
Number of Participants With Major Bleeding
Time Frame: 90 days
Defined by the International Society on Thrombosis and Haemostasis (ISTH) as overt bleeding associated with a decrease in the hemoglobin level of ≥2 g/dL, which led to transfusion of two or more units of packed red blood cells, occurred in a critical site, or contributed to death.
90 days
Number of Participants With Clinically Relevant Non-Major Bleed
Time Frame: 90 days
Clinically relevant non-major bleeding, as per the standardized definition by the ISTH, is any signs or symptoms of hemorrhage not meeting criteria for major bleeding but associated with medical intervention, unscheduled in-person contact with a healthcare professional or need for hospitalization or increased level of care.
