SMART-I: SiroMax™ Multi-Center coronary artery lesion treatment - safety and feasibility study of SiroMax SCB in ISR and DNSV

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

and/or planned PCI of the target vessel within 12 months post procedure * Currently participating or planning to participate, within 24 months of the index procedure, in an investigational drug or device trial * Patient is a recipient of a heart transplant * Known hypersensitivity or contraindication to aspirin, heparin, bivalirudin, or contrast agent * History of allergic reaction or

cells/mm3 or \>700,000 cells/mm3 or a white blood cell count of \<3,000 cells/mm3 * Known renal insufficiency (e.g. serum creatinine \>2.5mg/dL, or creatinine clearance ≤30 mL/min), or subject on dialysis, or acute kidney failure confirmed by 50% increase of serum creatinine within 48 hours before procedure and/or decrease in urine output * Subject with history of New York Heart Association (NYHA) class III or IV heart failure * History of bleeding diathesis, active peptic ulcer or GI bleeding within prior 6 months or coagulopathy or will refuse blood transfusions * Planned surgery that would cause interruption in recommended DAPT duration per current guidelines * History of a stroke within 6 months prior to the index procedure * Concurrent life conditions with a life expectancy of less than 24 months * In Investigator's opinion, the patient is not a good candidate for the study * Left ventricular ejection fraction \< 30% * Unprotected left main coronary artery disease with ≥ 50% stenosis * Target lesion at a bifurcation Note: A target lesion near a bifurcation is allowed if only a single vessel (either main vessel or side branch) is to be treated * Evidence of extensive thrombus or dissection in target lesion * Chronic total occlusion (CTO) in target lesion * \>30% residual stenosis after pre-treatment of target lesion * Target lesion is located in the left main or within any arterial or venous graft * Target lesion is in a side branch that is "jailed" by a main vessel stent * \> 50% stenosis of an additional proximal lesion or clinically significant distal lesion (in a vessel \>2.0mm RVD) to the target or non-target lesion * Target vessel is excessively tortuous, defined as more than one bend \> 90° to reach target lesion * Exclusion Criteria (Additional for ISR arm): * Target lesion is the 3rd or greater stent failure (i.e., more than two \[2\] layers of stent are present at any segment of the target lesion) * Target vessel had any previous vascular brachytherapy treatment or is planned to undergo brachytherapy at index procedure * If single-layer ISR, any previous treatment (other than balloon angioplasty alone) of the target vessel for restenosis If double-layer ISR, any treatment (other than balloon angioplasty alone) of the double-layer ISR restenosis * Exclusion Criteria (Additional for PK Sub-Study): * Any limus family (Zotarolimus, Everolimus, Sirolimus etc.) eluting device has been placed/used in any part of the body within 3 months prior to the index procedure including any non-target lesion treated during
