Enoxaparin 20mg Versus 30mg Subcutaneously Once Daily in Elderly Patients With Impaired Renal Function

September 8, 2017 updated by: Nibal Chamoun, Lebanese American University

Evaluation of Non-Surgical Venous Thromboembolism Prophylaxis Dosing Strategies: Enoxaparin 20mg Versus 30mg Subcutaneously Once Daily in Elderly Patients With Impaired Renal Function

This is a clinical trial including non-surgical patients, 70 years of age or older, with renal impairment requiring pharmacological venous thromboembolism prevention during hospitalization. Patients are randomized to receive either 20 mg or 30mg of enoxaparin. Both dosing regimens of enoxaparin have been approved for thromboprophylaxis in impaired kidney function in different countries. Therefore, this study aims to evaluate the efficacy and safety of enoxaparin 20mg versus 30mg subcutaneously daily by comparing anti-xa levels, thrombosis and bleeding events.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

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.
Outcome Measure
Measure Description
Time Frame
Peak anti-Xa levels
Time Frame: Day 3 of thromboprophylaxis
Peak anti-Xa levels, drawn 4 hours after the enoxaparin dose is given
Day 3 of thromboprophylaxis

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Trough anti-xa levels
Time Frame: Day 3 of thromboprophylaxis
Trough anti-Xa levels, drawn right before the third enoxaparin dose is given
Day 3 of thromboprophylaxis
Bleeding according to the GUSTO bleeding criteria.
Time Frame: Bleeding within 30 days will be assessed from randomization till date of bleeding or date of discharge, whichever comes first.
Bleeding within 30 days will be assessed from randomization till date of bleeding or date of discharge, whichever comes first.
Objectively confirmed symptomatic or asymptomatic venous thromboembolism (VTE) including both deep vein thrombosis (DVT) and or pulmonary embolism (PE).
Time Frame: Venous thromboembolism (VTE) within 30 days will be assessed from randomization till date of VTE or date of discharge, whichever comes first.
Chart documentation of objectively detected DVT by either bilateral venography or duplex ultrasonography whereas PE detection by contrast enhanced computerized tomography scan (CT Scan) or Magnetic resonance imaging (MRI).
Venous thromboembolism (VTE) within 30 days will be assessed from randomization till date of VTE or date of discharge, whichever comes first.
