難治性狭心症 II 患者における冠状静脈洞レジューサーの有効性 (COSIRA-II)
To demonstrate the safety and effectiveness of the Shockwave Reducer for treatment of patients with refractory angina pectoris treated with maximally tolerated guideline-directed medical therapy who demonstrate objective evidence of reversible myocardial ischemia in the distribution of the left coronary artery and who are deemed unsuitable for revascularization. A non-randomized single-arm registry will further assess the safety and effectiveness of the Shockwave Reducer in selected subjects with reversible myocardial ischemia in the distribution of the right coronary artery and who are deemed unsuitable for revascularization, subjects without documented obstructive coronary disease and abnormal coronary flow reserve (ANOCA), and subjects who cannot complete an exercise tolerance test due to lower limb amputation (above the ankle) or other physiologic condition with documented chronic mobility or balance issues that require the use of a walking aid.

- Must have attempted treatment with the maximally tolerated dose of at least three of the four (preferably all four) approved classes of anti-anginal agents: long-acting nitrates, calcium channel blockers (either a dihydropyridine or a non-dihydropyridine), beta blockers, and ranolazine. The regimen must be stable for at least 30 days prior to enrollment, must remain stable from enrollment to randomization, and there must be no intent to change the medical regimen for at least 12 months after randomization Note: If the dose of a medication was increased or decreased for a temporary period and then returned to the original dose, which will then be continued for at least 12 months after randomization, the subject may be immediately enrolled without needing to otherwise requalify
- Subject has either no treatment options for revascularization by coronary artery bypass grafting or by percutaneous coronary intervention, or is otherwise unsuitable or high risk for revascularization as determined by the local heart team, and confirmed by a Central Screening Eligibility Committee
- Evidence of either exercise or pharmacologically induced reversible ischemia severity by stress echo, nuclear study, PET, perfusion MRI, CT perfusion, FFR-CT, FFR, iFR, or other non-hyperemic FDA approved tests (such as diastolic hyperaemia free ratio [DRF] or resting full-cycle ratio [RFR] in the distribution of the left coronary artery (LCA), performed within 12 months prior to enrollment Note: If the subject has evidence of ischemia in both the LCA and RCA distributions, the extent of ischemia must be greater in the LCA distribution Note: The qualifying assessment must be performed after any myocardial infarction, CABG, or successful PCI within the prior 12 months. For subjects with multiple assessments, the one performed closest to enrollment will serve as the qualifying study

Note: If a pathway to coronary revascularization is present which, in the opinion of the local heart team, is reasonably low risk and reasonably likely to provide long-term symptom relief and the subject refuses the revascularization procedure, the patient is ineligible for randomization
Procedural Angiographic/Hemodynamic Randomization Exclusion Criteria:
- Mean right atrial pressure greater than 15 mmHg assessed during the final screening procedure for eligibility assessment and potential randomization
- Anomalous or abnormal CS anatomy (e.g., tortuosity, aberrant branch, persistent left superior vena cava [SVC]) as demonstrated by angiogram

Single-arm Registry (Unblinded, Non-Randomized Treatment Arm) Inclusion/Exclusion Criteria:
Subject can be included in the single-arm registry if they fall into one of the three categories with inclusions and exclusion criteria as described below.
Predominant right coronary disease subjects (RCA):
-
Reversible ischemia: Subjects with evidence of either exercise or pharmacologically induced reversible ischemia by stress echo, nuclear study, PET, perfusion MRI, CT perfusion, FFR-CT, FFR, iFR, or other non-hyperemic FDA approved or cleared tests (such as DFR or RFR) in the distribution of the right coronary artery (RCA), performed within 12 months prior to enrollment.
Note: If the subject has evidence of ischemia in both the LCA and RCA distributions, the extent of ischemia must be greater in the RCA distribution
Note: The qualifying assessment must be performed after any myocardial infarction, CABG, or successful PCI within the prior 12 months. If the anti-anginal medication regimen is permanently changed after the assessment of ischemia, the test must be repeated. For subjects with multiple assessments, the one performed closest to enrollment will serve as the qualifying study
-
Obstructive CAD: Three-vessel coronary angiography performed within the 12 months prior to enrollment demonstrating obstructive CAD (visually assessed diameter stenosis of ≥70% or ≥50% - <70% with fractional flow reserve (FFR) value of ≤0.80 or an iFR or other FDA-approved/cleared non-hyperemic physiological assessment (such as DFR or RFR) of ≤0.89 in one or more lesions) in the RCA (main epicardial vessels or branches) that is not suitable for and will not be treated with PCI or CABG as determined by the local heart team.
Note: The qualifying assessment must be performed after any myocardial infarction, PCI or CABG within the prior 12 months. For subjects with multiple assessments, the one performed closest to enrollment will serve as the qualifying study
-
In addition to the above inclusion criteria, subjects must meet all inclusion criteria (except clinical inclusion #5 and angiographic inclusion #1) and none of the exclusion criteria of the main randomized trial
Non-obstructive coronary artery disease subjects (ANOCA)
-
Abnormal Coronary Flow Reserve (CFR): subjects must have either abnormal PET CFR (< 2.0), abnormal perfusion CMR (cardiac MRI) CFR (<1.85), or abnormal invasive CFR (<2.5) in at least one main epicardial coronary artery performed within 12 months prior to enrollment
Note: Subjects may or may not have evidence of either exercise or pharmacologically induced reversible ischemia by stress echo, nuclear study, PET, perfusion MRI, or CT perfusion
-
Non-obstructive CAD: subjects have non-obstructive coronary disease (estimated diameter stenosis in all coronary lesions is <50% and (if performed) FFR ≥0.81 or a non-hyperemic test is ≥0.90) demonstrated on three-vessel coronary angiography performed within the 12 months prior to enrollment. If an estimated diameter stenosis is ≥50% to <70%, the patient may still qualify if FFR ≥0.81 or a non-hyperemic test is ≥0.90 in that vessel. If both FFR and a non-hyperemic test are performed, both must be negative.
Note: The qualifying 3-vessel angiogram must be performed after any myocardial infarction, PCI or CABG within the 12 months prior to enrollment. For patients with multiple 3-vessel angiograms, the one performed closest to enrollment will serve as the qualifying study
-
In addition to the above inclusion criteria, subjects must meet all inclusion criteria (except clinical inclusion #5 and angiographic inclusion #1) and none of the exclusion criteria of the main randomized trial
Subjects unable to complete ETT
- Subjects must be unable to complete the required COSIRA-II exercise tolerance test due to lower limb amputation (above the ankle) or other physiologic condition with documented chronic mobility or balance issues that require the use of a walking aid (e.g., wheelchair, cane, rollator, crutches, or knee walker).
- In addition to the above inclusion criteria, subjects must meet all inclusion criteria (except clinical inclusion #6) and none of the exclusion criteria of the main randomized trial
Prior to inclusion in single-arm registry, all subjects will be reviewed by the Central Screening Eligibility Committee to ensure that they meet registry inclusion criteria and are not eligible for enrollment into the randomized study.
