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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age 18 or more
  • Angiographically confirmed multivessel CAD with involved LAD and critical (>70%)lesion in at least one (apart LAD) major epicardial vessel amenable to both PCI and CABG
  • Indication for revascularization based upon symptoms of angina and/or objective evidence of myocardial ischaemia
  • Patient is willing to comply with all follow-up visits
  • Patient signed an Informed Consent

Exclusion Criteria:

  • Severe congestive heart failure (class III or IV according to NYHA, or pulmonary edema, cardiogenic shock) at the time of enrollment
  • Prior surgery with the opening of pericardium or pleura
  • Prior stroke (within 6 months)or more than 6 months if there are substantial neurological defects

  • One or more chronic total occlusions in major coronary territories
  • Left main stenosis (at least 50% diameter stenosis)
  • Acute ST-elevation MI within 72 hours prior to enrollment requiring revascularization
  • Planned simultaneous surgical procedure unrelated to coronary revascularization (e.g. valve repair/replacement, aneurysmectomy, carotid endarterectomy or carotid stenting)
  • Contraindication to either CABG, MIDCAB or PCI/DES because of a coexisting clinical condition
  • Significant leukopenia, neutropenia, thrombocytopenia, anemia, or known bleeding diathesis.
  • Intolerance or contraindication to aspirin or both clopidogrel and ticlopidine
  • Extra-cardiac illness that is expected to limit survival to less than 5 years e.g. oxygen-dependent chronic obstructive pulmonary disease, active hepatitis or significant hepatic failure, severe renal disease

  • Concurrent enrollment in another clinical trial
  • Patient inaccessible for follow-up visits required by protocol

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

First stage: implantation of the internal mammary artery into LAD in MIDCAB/TECAB procedure Second stage: PCI with drug eluting stents in other coronary arteries qualified for revascularization within 36 hours after surgery
ACTIVE_COMPARATOR: Coronary Artery Bypass Grafting
Procedure: Coronary Artery Bypass Grafting
Coronary artery bypass grafting with sternotomy on or off the pump at discretion of the operator.

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
Possibility defined by means of (1) a % of pts with complete hybrid procedure according to study protocol, and (2) a % of conversion to standard CABG. Safety defined as a occurrence of MACE such as death, MI, stroke, TVR, or major bleeding.
Time Frame: 1 year
1 year

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
Postprocedure and follow up angiographic measurements as patency of grafts and restenosis in revascularized segments
Time Frame: 1 year
1 year
Assessment of quality of life of alive study participants according to SF-36 Health Survey version 2
Time Frame: 1 year
1 year
Cost-effectiveness defined as a cost of revascularization procedure and costs of hospitalizations in both groups.
Time Frame: 1 year
1 year
