Efficiency of a New Therapy to Treat Stenosis of Coronary Vessels in Comparison With Two Already Admitted Therapies

May 15, 2007 updated by: University Hospital Tuebingen

Local-Tax Trial: Local Intracoronary Administration of Paclitaxel After Stent Implantation for Prevention of Restenosis in Comparison With Stent Implantation Alone and With Implantation of a Paclitaxel-Eluting Stent

The aim of the study is to examine the efficacy of Paclitaxel injection after a stent implantation in patients with stenosis in native coronary arteries to prevent restenosis in comparision with two admitted therapies.

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

The aim of the study is to examine whether in patients with stable or instable Angina pectoris and/or documented myocardial ischemia in the presence of de-novo stenosis in native coronary arteries with a degree of stenosis between 50 % and 99 % an additional local administration of paclitaxel after implantation of a conventional stent is superior to the implantation of a conventional stent alone with respect to late lumen loss (LLL). In case of superiority it will be examined whether an additional local administration of paclitaxel after implantation of a conventional stent is not inferior to the implantation of a paclitaxel-eluting stent with respect to late lumen-luss. Is this the case, superiority will be tested.

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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

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
Time Frame
The primary objective is the angiographical determination of the late lumen loss in the stent and/or persistent area, 6 month after stent implantation.
Time Frame: week 26 +/- 14 days
week 26 +/- 14 days

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
Time Frame
The angiographical determination of the binary restenosis rate, defined as diameter stenosis of at least 50 % in the stent and / or persistent area, 6 months after stent implantation.
Time Frame: week 26 +/- 14 days
week 26 +/- 14 days
The angiographical determination of the degree of stenosis, defined as percentage diameter stenosis in the stent and /or persistent area, 6 months after stent implantation.
Time Frame: week 26, +/- 14 days
week 26, +/- 14 days
Tthe angiographical determination of the minimal lumen diameter in the stent and / or persistent area, 6 months after stent implantation.
Time Frame: week 26, +/- 14 days
week 26, +/- 14 days
The 6 months after stent implantation determined combined endpoint of abrupt and subabrupt closure of the target vessel, target lesion revascularisation and major adverse cardiac events including myocardial infarction and death.
