Randomized, Multicenter, Double-blind, Vancomycin-controlled Study to Evaluate the Efficacy of Ethanol Lock Solution for the Curative Treatment of Implantable Venous Access Port Infection Due to Coagulase-negative Staphylococci (Etha-LOCK)

July 25, 2016 updated by: University Hospital, Clermont-Ferrand
Implantable venous access port infections are mainly due to coagulase negative staphylococci and may be managed by antibiotic lock therapy with retention of the port. Most of the time a vancomycin lock is used. Experimental data show that vancomycin may be poorly effective in eradicating the staphylococcal biofilm in the port. Another disadvantage of Vancomycin-containing lock solution is the occurrence of resistant organisms and the risk of catheter occlusion. Ethanol-containing lock solution is highly effective in vitro and does not expose to the risk of emergence resistance.

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

Type of study: multi-center, randomized, double-blind, parallel-group, controlled clinical trial.

Number of centers: 9 French centers in Auvergne and Rhône-Alpes regions

Medical product Ethanol 40% + Enoxaparine 400UI/ml Versus Vancomycin 5 mg/ml + Héparine 2500UI/ml

Patients

Patients eligible for inclusion will be randomized to one of the two groups:

  • Experimental group: 90 patients will receive 10 injections of ethanol lock solution in implantable venous access port during the first 10 days of the study.
  • Control group: 90 patients will receive 10 injections of vancomycin lock solution in implantable venous access port during the first 10 days of the study.
  • For each group, in case of bacteraemia, the lock therapy is associated with a systemic antibiotic therapy using another venous line and optimized by a specialist in infectious diseases.

Study Performance

Patients will be assessed at baseline D0, 3 days (D3), 10 days (D10), 14 weeks (W14) after D0 as follows:

Visit 1 (D0 - baseline):

  • Signature of an informed consent form.
  • Demographic and clinical characteristics (sex, age, disease associated with implantable venous access port, implantable venous access port infection data, bacteraemia data)

Days 1 to 10

  • Injection of ethanol or vancomycin lock solution in implantable venous access port
  • Ethanolemia 30 minutes after injection, on first day
  • Side effects evaluation

Visit 2 (D3) and Visit 3 (D10)

  • Side effects evaluation
  • Blood culture
  • Bacteraemia data (antibiotic therapy modification)

Phone contact each week from week 2 to week 13

End Visit (W14)

  • Side effects evaluation
  • Blood culture
  • Bacteraemia data (antibiotic therapy modification)

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.
