Clinical Trial Summary

The NIREUS study aims to demonstrate angiographic non-inferiority for the BioNIR Ridaforolimus Eluting Coronary Stent System (hereafter referred to as BioNIR) in comparison to the Resolute zotarolimus-eluting stent (hereafter referred to as Resolute).

The trial hypothesis is that the BioNIR is non-inferior to the Resolute for the primary endpoint of angiographic in-stent late loss at 6 months.

Description:

This is a prospective, multi-center, single-blind, two-arm, 2:1 randomized clinical trial.

Randomization will be stratified by the presence of medically treated diabetes vs. no medically treated diabetes and by site. Lesions planned to be treated must be declared and recorded at time of randomization.

Angiographic follow-up will be performed at 6 months. Clinical follow-up will be performed at 30 days, 6 months, and 1, 2, 3, 4, and 5 years post randomization.

The Primary Endpoint is in-stent late loss at 6 months as measured by the angiographic core laboratory.

Angiographic Secondary Endpoints to be evaluated at 6 months are:

• In-segment late loss

• Follow-up percent diameter stenosis (in-stent and in-segment)

• Binary restenosis (in-stent and in-segment)

• Length and patterns of angiographic restenosis (Mehran classification)

Clinical Secondary Endpoints to be evaluated at 30 days, 6 months, and 1, 2, 3, 4 and 5 years, except as noted, are:

• Device, Lesion, and Procedure Success at time of baseline procedure

• Target lesion failure (TLF; the composite of cardiac death, target vessel-related MI, or ischemia-driven TLR)

• Major adverse cardiac events (MACE; the composite rate of cardiac death, any MI or ischemia-driven TLR)

• Target vessel failure (TVF; the composite rate of death, target vessel-related MI, or ischemia-driven TVR)

• Overall Mortality

• Cardiac Death

• Myocardial Infarction

• Target Vessel Related MI

• Ischemia-driven TLR

• Ischemia-driven TVR

• Stent Thrombosis (ARC definite and probable)

Eligibility

Inclusion Criteria:

• Age = 18 years

• Patient with an indication for PCI including angina (stable or unstable), silent ischemia (in absence of symptoms a visually estimated target lesion diameter stenosis of =70%, a positive non-invasive stress test, or FFR =0.80 must be present), NSTEMI, or recent STEMI. For STEMI the time of presentation to the first treating hospital, whether a transfer facility or the study hospital, must be >24 hours prior to randomization and enzyme levels (CK-MB or Troponin) demonstrating that either or both enzyme levels have peaked.

• Non-target vessel PCI are allowed prior to randomization depending on the time interval and conditions as follows:

a. During Baseline Procedure: i. PCI of non-target vessels performed during the baseline procedure itself immediately prior to randomization if successful and uncomplicated defined as: <50% visually estimated residual diameter stenosis, TIMI Grade 3 flow, no dissection = NHLBI type C, no perforation, no persistent ST segment changes, no prolonged chest pain, no TIMI major or BARC type 3 bleeding.

b. Less than 24 hours prior to Baseline Procedure: i. Not allowed (see exclusion criteria #3). c. 24 hours-30 days prior to Baseline Procedure: i. PCI of non-target vessels 24 hours to 30 days prior to randomization if successful and uncomplicated as defined above.

ii. In addition, in cases where non-target lesion PCI has occurred 24-72 hours prior to the baseline procedure, at least 2 sets of cardiac biomarkers must be drawn at least 6 and 12 hours after the non-target vessel PCI. If cardiac biomarkers are initially elevated above the local laboratory upper limit of normal, serial measurements must demonstrate that the biomarkers are falling.

d. Over 30 days prior to Baseline Procedure: iii. PCI of non-target vessels performed greater than 30 days prior to procedure whether or not successful and uncomplicated.

• Patient or legal guardian is willing and able to provide informed written consent and comply with follow-up visits and testing schedule.

Angiographic inclusion criteria (visual estimate):

• Treatment of up to three de novo target lesions, maximum of one de novo target lesion per vessel

• Target lesion(s) must be located in a native coronary artery with visually estimated diameter of =2.5 mm to =4.25 mm and diameter stenosis =50% to <100%.

• Lesion must be =28 mm long and can be covered by a single study stent with maximum length of 33 mm (note: multiple focal stenoses may be considered as a single lesion and be enrolled if they can be completely covered with one stent).

Exclusion Criteria:

• Non-target lesion PCI in the target vessel within 12 months of the baseline procedure.

• White blood cell (WBC) count <3,000 cells/mm3.

• Clinically significant liver disease.

• Renal disease as defined by an estimated creatinine clearance <40 mL/min using Cockcroft-Gault equation.

• Active peptic ulcer or active bleeding from any site.

• Bleeding from any site within the prior 8 weeks requiring active medical or surgical attention.

• History of bleeding diathesis or coagulopathy or likely to refuse blood transfusions.

• If femoral access is planned, significant peripheral arterial disease which precludes safe insertion of a 6F sheath.

• Cerebrovascular accident or transient ischemic attack within the past 6 months, or any permanent neurologic defect attributed to CVA.

• Known allergy to the study stent components, whether in the BioNIR or Resolute, e.g. cobalt, nickel, chromium, molybdenum, Carbosil®, PBMA, Biolinx polymer, or limus drugs (ridaforolimus, zotarolimus, tacrolimus, sirolimus, everolimus, or similar drugs or any other analogue or derivative or similar compounds).

• Known allergy to protocol-required concomitant medications such as aspirin, or DAPT (clopidogrel, prasugrel, ticagrelor), or heparin and bivalirudin, or iodinated contrast that cannot be adequately pre-medicated.

• Any co-morbid condition that may cause non-compliance with the protocol (e.g. dementia, substance abuse, etc.) or reduced life expectancy to <24 months (e.g. cancer, severe heart failure, severe lung disease).

• Patient is participating in or plans to participate in any other investigational drug or device clinical trial that has not reached its primary endpoint.

• Women who are pregnant or breastfeeding (women of child-bearing potential must have a negative pregnancy test within one week before treatment).

• Women who intend to become pregnant within 12 months after the baseline procedure (women of child-bearing potential who are sexually active must agree to use a reliable method of contraception from the time of screening through 12 months after the baseline procedure).

• Patient has received an organ transplant or is on a waiting list for an organ transplant.

• Patient is receiving or scheduled to receive chemotherapy within 30 days before or any time after the baseline procedure.
