Primary purpose: TREATMENT

Brief summary: Prospective, randomized controlled, single-blind, multicenter, clinical trial to demonstrate the safety and efficacy of the SELUTION SLR 014 PTCA DEB for treatment of de novo lesions in small coronary vessels, defined as reference vessel diameter (RVD) of 2.00 mm to 2.75 mm, in support of a pre-market approval (PMA) application to the United States (US) FDA.

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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Clinical Inclusion Criteria

4. Subject can tolerate dual antiplatelet therapy with aspirin, plus either Clopidogrel, Prasugrel, or Ticagrelor. (Note: For subjects requiring oral anticoagulation, aspirin may be omitted based on investigator discretion).
5. Subject has life expectancy \> 1 year in the opinion of the investigator.
6. Subject is willing and able to provide informed consent and comply with study procedures and required follow-up evaluations.

PK Sub- Study Inclusion Criteria:

Subjects must meet all of the main protocol inclusion criteria to participate in the PK sub-study. Subjects must also meet the following additional PK sub-study inclusion criteria:

1. Subject is willing and able to provide informed consent for the PK sub-study and comply with the PK sub-study procedures and required follow-up evaluations.

Imaging Inclusion Criteria

Subject's target lesion(s) must meet all of the following angiographic criteria for the subject to participate in the trial:

2. Up to two (2) non-target lesions in up to two (2) non-target vessels may be treated, but successful PCI of the non-target lesions must be completed before randomization and treatment of the target lesion.
3. Target lesion is ≤ 36 mm in length.
4. Target lesion has diameter stenosis \> 50% and ≤ 99% with distal flow at least thrombolysis in myocardial infarction (TIMI) 2.
5. Target vessel has RVD of ≥ 2.00 mm and ≤ 2.75 mm \[by visual assessment\].
6. Target lesion is within a native coronary artery or major branch.
7. A target lesion within or near a bifurcation is allowed only if a single vessel (either main vessel or side branch) is to be treated.
8. The identified target lesion has high probability (\> 70%) for successful treatment with approved pre-treatment techniques and DEB alone.
