Outcome measures
Primary outcome
The primary endpoint of the study is target lesion failure (TLF) defined as a
composite of clinically-driven target lesion revascularization, target vessel
related myocardial infarction, or cardiac death that could not be clearly
attributed to a vessel other than the target vessel at 12-months
post-procedure.
Secondary outcome
•Procedural endpoints: Lesion success, Device success, Procedure success.
•Clinical endpoints through 18 months post procedure and annually from 2 to 5
years post procedure: Target lesion revascularization (TLR) (total and
clinically driven), Target vessel revascularization (TVR) (total and clinically
driven), Target vessel failure (TVF) and its individual components, Major
adverse cardiac events (MACE) (death, Q wave or WHO-defined non-Q wave
myocardial infarction, emergent bypass surgery, or repeat target lesion
revascularization) and its individual components.
•Safety endpoints through 18 months post procedure and annually from 2 to 5
years post procedure: Stent thrombosis (acute, sub-acute, late, very late),
Bleeding events, Death (cardiac and non-cardiac), Myocardial Infarction (Q wave
or WHO-defined non-Q wave), Stroke (hemorrhagic and non- hemorrhagic).
•Patient reported outcomes as measured by a quality of life (QOL) survey at
baseline, 30 days, 6 months, 12 months, 18 months, and from 2-5 years post
procedure.
Background summary
Restenosis remains a frequent cause of late failure after initially successful
coronary angioplasty occurring in as many as 20-40% of procedures performed.
Restenosis following stenting is primarily a result of neointimal hyperplasia.
An increasing body of evidence has emerged demonstrating that local delivery of
pharmacologic agents that inhibit cellular proliferation, and therefore
neointimal hyperplasia, may lead to improved outcomes following coronary
stenting. The advantages of local drug delivery include sufficient drug
concentration in the treated segment while limiting systemic exposure and
potential side effects.
The first agents to be studies for the prevention of coronary restenosis on a
drug-eluting stent platform were sirolimus and paclitaxel. Sirolimus has an
anti-proliferatieve action in T cells and smooth muscle cells and prevents
proliferation and migration of smooth muscle cells in several models of
restenosis and vascular disease.
Study objective
The primary objective of this study is to evaluate the target lesion failure
rate of the Conor Sirolimus-eluting Coronary Stent System in lesions up to 28
mm in length in native coronary arteries with a reference vessel diameter of
2.5 mm to 3.5 mm compared to an OPC derived from historical data.
Study design
The RES-Elution II NR study is a prospective, multi-center, single-arm,
open-label study for the treatment of
lesions in native coronary arteries. Clinical follow-up will take place at 30
days, 6 months, 12 months, 18 months
and annually from 2 through 5 years post-procedure.
Intervention
Standard procedure of balloon angioplasty with stenting procedure and
con-comitant anti-platelets treatment.
Study burden and risks
The following risks relating to standard PTCA, stenting, and angiography may
occur (listed in order of severity): Death; intima dissection (additional stent
placing or surgical revascularisation), injury to the artery requiring
emergency coronary artery bypass graft; Myocardial ischemia and/or infarction;
Stroke/transient ischemic attack; Cardiac tamponade, Dissection, perforation,
or rupture of the coronary artery; Embolism; Stent thrombosis/occlusion (early
or late); Total occlusion of the artery; Restenosis of the stented artery;
Coronary perforation; Aneurysm, pseudoaneurysm, or arteriovenous fistula;
Arrhythmias including tachyarrhythmias, bradyarrhythmias or cardiac arrest;
Hemorrhage, possibly requiring transfusion, as a result of the procedure or
associated medications; Renal insufficiency or renal failure; Respiratory
failure; Shock/pulmonary edema; Abrupt vessel closure or spasm;
Hypotension/hypertension; Allergic reaction or hypersensitivity (to contrast,
antiplatelet therapy, stent materials including metal, drug or polymers);
Peripheral ischemia/peripheral nerve injury; Infection or fever; Unstable
angina; atypical angina; chest pain; Pain/reaction at catheter insertion site;
balloon rupture; Stent migration; Failure to deliver the stent to the intended
site of treatment; Stent misplacement; Incomplete stent apposition; Stent
compression; Stent fracture; Vasospasm; Hematoma. Deformed stents that cannot
be implanted could also lead to problems associated with stent retrieval which
could in turn expose the patient to longer procedure times and increased x-ray
exposure.
Potential adverse events not outlined above but listed in the CYPHER® SELECT
Plus and/or CYPHER® product labeling (Cordis Corporation) P020026 that may be
related to sirolimus or to the sirolimus drug coating include: Immune
suppression, especially in patients with hepatic insufficiency or who are
taking medications that inhibit CYP3A4 or P-glycoprotein; Hypersensitivity, to
the drug (sirolimus or its excipients) or to the polymer (or individual
components) including anaphylactic/anaphylactoid type reactions; Changes in
lipid metabolism which may include hypertriglyceridemia or
hypercholesterolemia; Abnormal liver function tests; Anemia, low white blood
cell count, or low platelet count; Joint pain/discomfort; Diarrhea; Increased
cholesterol or increased triglycerides; Low blood potassium levels; Infections;
Interstitial lung disease; Lymphoma and other malignancies.
The bruden for the patient exists of ballon angioplasty with stenting procedure
and anticoagulant therapy.
The patient will be admitted to the hospital for the ballon angioplasty with
stenting procedure for 1-2 days.
Clinical follow-up will take place at 30 days, 6 months, 12 months, 18 months
and annually from 2 through 5 years post-procedure. During this visits patient
will be asked to complete a QoL questionnaire, ECG will be taken and the
investigator will assess the patient's angina status. After 6 months an
identical telephone visit will be done without the ECG.
