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:
1. A single, target lesions that meet criteria can be treated in a single vessel. No non-target lesions can be treated within the target vessel in the index procedure. Non-target lesions within the target vessel can be staged for treatment > 30 days from the index procedure.
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 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 for successful treatment with approved pre-treatment techniques and DEB alone based on Investigator assessment.
Exclusion Criteria:
- Clinical Exclusion Criteria
Subjects who meet any of the following clinical criteria will be excluded from the trial:
1. Subject with known hypersensitivity or allergy to Sirolimus or its analogues.
2. Subject presents with NSTEMI and rising biomarkers, or ongoing chest pain or is hemodynamically instable.
3. Subject with history of ST-elevation myocardial infarction (STEMI) within 30 days of the index procedure.
4. Subject with planned major surgery within 30 days following the index procedure.
5. Subject with planned treatment of lesion involving aorto-ostial location.

7. Subject with history (within 6 months prior to index procedure) of New York Heart Association (NYHA) class III or IV heart failure.
8. Subject with history of active peptic ulcer or gastrointestinal bleeding within 6 months of the index procedure or other inability to comply with the recommended duration of dual antiplatelet therapy (DAPT).
9. Subject is pregnant, breast-feeding or a woman of childbearing potential who plans pregnancy up to 1 year following index procedure.
10. Subjects with current documented left ventricular ejection fraction (LVEF) < 30%.
11. Subject is considered not able to tolerate at least 30 seconds of coronary occlusion for the target lesion treated.
12. Subjects is currently participating in another investigational drug or device study that has not completed primary endpoint follow-up.
13. Subject with definite clinically active COVID-19 infection defined as a positive COVID test within 24 hours of index procedure.
14. Subject has chronic renal insufficiency (dialysis dependent, or glomerular filtration rate \[GFR\] ≤ 30 ml/min/1.73 m2 within 30 days of index procedure) or had undergone renal transplantation.
PK Sub-Study Exclusion Criteria:
Subjects must meet none of the main protocol exclusion criteria to participate in the PK sub-study. Subjects will be excluded if any of the following additional PK sub-study exclusion criteria are met:
1. 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 non-target lesion(s) treated during the index procedure.
2. Planned intervention with any limus family (Zotarolimus, Everolimus, Sirolimus etc.) eluting device anywhere in the body within 6 months after the index procedure. Note: staged procedures >30 days after index procedure (Exclusion #6 of the main protocol) are permitted only in the main protocol, and are not permitted in this PK sub-study.
3. The subject is taking or has taken within the last 3 months any limus family medication(s) for any reason.
4. Subject is concurrently enrolled in the main protocol angiographic registry.
5. Subjects who are taking strong CYP3A4 Inhibitors within 14 days before the index procedure or plan to take the strong inhibitors during the study period. Strong inhibitors include: cobicistat; ritonavir; indinavir and ritonavir; itraconazole; ketoconazole; lopinavir and ritonavir; paritaprevir and ritonavir and ombitasvir (and/or dasabuvir); posaconazole; saquinavir and ritonavir; tipranavir and ritonavir; elvitegravir and ritonavir; telithromycin; voriconazole; ceritinib; clarithromycin; idealalisib; nefazodone; nelfinavir.
6. Subjects who are taking strong CYP3A4 Inducers within 14 days before the index procedure or plan to take the strong inducers during the study period. Strong inducers include apalutamide; carbamazepine; enzalutamide; ivosidenib; lumacaftor and ivacaftor; mitotane; phenytoin; rifampin; St. John's wort.
