Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prospective, randomized controlled, single-blind, multicenter, clinical trial

The study will enroll up to 910 randomized subjects, up to 30 subjects in a parallel angiographic substudy, and up to 20 subjects in a parallel pharmacokinetic (pK) substudy, at up to 80 sites in the US, Canada, Brazil, Japan and Europe. A minimum of 50% of the subjects will be enrolled in the US.

Subjects who present with chronic coronary syndrome (CCS), unstable angina or stabilized non-ST elevation myocardial infarction (NSTEMI) with an indication for percutaneous coronary intervention (PCI) with planned intervention for de novo lesions in small coronary vessels (RVD 2.00 mm to 2.75 mm) and meeting all eligibility criteria will be randomized 1:1 to treatment of the identified target lesion with either the SELUTION SLR 014 PTCA DEB or contemporary DES.

Randomized Cohort:

* Intervention (DEB Strategy): Subjects randomized to the SELUTION SLR 014 PTCA DEB arm will receive lesion preparation according to the 3rd drug coated balloon (DCB) consensus (optimal balloon angioplasty with adjunct treatment using high-pressure balloon, intravascular lithotripsy, laser, rotational or orbital atherectomy, cutting or scoring balloon at the discretion of the operator as needed to reduce diameter stenosis to ≤ 30%). Subjects with lesions that are then best treated by provisional stenting (flow-limiting dissection, residual stenosis \> 30%) will receive a DES instead of the SELUTION DEB but remain in the SELUTION DEB group (intention to treat analysis). The DEB should not be used after DES implant.
* Control (DES): Subjects randomized to the DES arm will receive treatment using any FDA approved "limus-based" DES, as per standard institutional practice.

Angiographic Substudy:

The angiographic substudy is a parallel registry consisting of up to 30 additional consecutive subjects meeting all eligibility criteria treated with the SELUTION DEB recruited at select study sites. These subjects will undergo angiography at 12 months post-procedure. Clinical follow-up will not extend beyond 12 months in this cohort.

Pharmacokinetic (pK) Substudy:

The pKsubstudy is a parallel registry consisting of up to 20 additional consecutive subjects meeting all eligibility criteria treated with the SELUTION DEB recruited at select study sites. This study will be conducted under an approved substudy protocol and will include blood draws at regular intervals to characterize the pK plasma profile of sirolimus.

Primary Endpoint:

Target lesion failure (TLF), defined as the composite of cardiac death, target-vessel myocardial infarction (MI) or clinically-driven target lesion revascularization (TLR) at 12 months. MI includes spontaneous (Type 1) MI using the 4th Universal Definition of Myocardial Infarction (UDMI) and peri-procedural MI using the Society for Cardiac Angiography and Intervention (SCAI) definition.

Participants Outcome Assessors

The randomized trial is a single-blind study. The physician performing the index procedure as well as study site personnel present at the index procedure will not be blinded, however every effort will be made to maintain blinding for the following:

* Subjects and their families
* Site personnel involved in conducting study assessments during follow-up Unblinding will only occur to protect subject rights, welfare, or well-being. The angiographic and pK substudy cohorts will not be blinded.

The Clinical Events Committee (CEC) will be blinded to the treatment arm during the adjudication process.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

SELUTION SLR 014 PTCA DEB

SELUTION Sustained Limus Release (SLR) 014 Percutaneous Transluminal Coronary Angioplasty (PTCA) Drug Eluting Balloon (DEB)

The SELUTION SLR 014 PTCA DEB is a minimally invasive, single use and sterile Sirolimus coated PTCA balloon catheter.

The SELUTION SLR 014 PTCA DEB is available with balloon diameters from 2.0 to 3.0 mm and lengths of 15 to 40 mm for the purpose of the De Novo IDE trial

Group Type EXPERIMENTAL

PCI with SELUTION SLR DCB

Intervention Type DEVICE

After target lesion pre-dilatation and preparation , a SELUTION SLR 014 PTCA DEB study device should be selected with nominal diameter equal to the RVD of the target lesion (1:1 ratio) and length that allows approximately 2.00 mm longer than the proximal and distal edges of the target lesion (defined as the proximal and distal extent of predilation). If IVUS is performed to assess RVD, and DEB upsizing is deemed clinically necessary for optimal results, a maximum nominal DEB diameter of 3.0 mm is permitted. The SELUTION SLR 014 PTCA DEB should then be delivered, positioned in and deployed per instructions per use. The balloon should be inflated for 60 seconds provided that the patient can tolerate this duration. The minimum inflation time is 30 seconds.

Control Treatment

any FDA approved "limus-based" Drug Eluting Stent, as per standard institutional practice

Group Type ACTIVE_COMPARATOR

PCI with FDA approved "-limus" DES

Intervention Type DEVICE

For subjects randomized to the control group (DES), the treating physician will choose an FDA cleared DES and follow lesion preparation and stent deployment according to the Instructions per use (IFU) and institutional practices.

The DES should be sized per IFU with respect to the vessel RVD. The use of IVUS or OCT is encouraged to guide optimal stent placement and assess final results. After DES deployment, additional balloon inflations should be performed as needed to obtain \< 30% residual diameter stenosis and resolve proximal or distal edge dissections greater than or equal to NHLBI grade B.
