Overview
The objective of this study is to establish reasonable assurance of safety and effectiveness of the Golazo® Peripheral Atherectomy System when used as indicated in 159 subjects with symptomatic infrainguinal peripheral arterial disease (PAD) in up to 20 investigational sites in the U.S.
Description
The investigation is a prospective, multicenter, non-randomized, single-arm, open-label pivotal clinical study. Subjects will undergo atherectomy treatment with the Golazo® Peripheral Atherectomy System and will then be followed 6-months post-procedure.
Eligibility
General inclusion criteria:
- Age ≥18 years
- Candidate for atherectomy of the peripheral vasculature in the lower limbs
- Life expectancy >1 year in the opinion of the investigator
- Resting ankle brachial index (ABI) ≤0.90, or ≤0.75 after exercise. Subjects with non-compressible arteries shall have a toe brachial index (TBI) assessment.
- Target limb Rutherford clinical classification category 3 to 5
- Suitable candidate for angiography and endovascular intervention in the opinion of the investigator
- Willing and able to comply with the protocol-specified procedures and assessments
- Informed consent granted
Angiographic inclusion criteria:
- Target lesion(s) defined as stenosis ≥70% by angiographic visual estimation
- Total treated lesion length ≤20 cm by angiographic visual estimation
- Target reference vessel diameter (RVD) ≥2.0 mm and ≤4.5 mm by angiographic visual estimation
- Target limb will have a minimum of one patent (less than 50% stenosis) below the knee (BTK) vessel crossing the ankle, distal to any target lesion, providing perfusion to the foot at baseline
General exclusion criteria:
- Active infection in the target limb
- History of an endovascular procedure or open vascular surgery on the target limb within the last 30 days
- Planned surgical or interventional procedure within 30 days after the index procedure
- Lesion in the contralateral limb requiring intervention during the index procedure or within next 30 days
- Critical limb ischemia (CLI) with Rutherford clinical classification category 6
- Significant acute or chronic kidney disease with a GFR <30 and/or requiring dialysis
- Acute myocardial infarction (non-ST-elevation myocardial infarction or ST-segment elevation myocardial infarction) or other uncontrolled comorbidity in the opinion of the investigator
- Myocardial infarction (MI) or stroke within two months of baseline evaluation
- Pregnant or lactating
- Subject is participating in another clinical investigation of a device, drug, or procedure that has not completed the study treatment or that clinically interferes with the endpoints of this study (post-approval registries are allowed as long as the investigator determines there is no clinical interference with study endpoints)
- Contraindication to antiplatelet, anticoagulant, or thrombolytic therapy
- Uncorrectable bleeding diathesis, platelet dysfunction, thrombocytopenia with platelet count <125,000/microliter, known coagulopathy, or international normalized ratio (INR) >1.5
- Known allergy to contrast agents or medications used to perform endovascular intervention that cannot be adequately medicated
- History of heparin-induced thrombocytopenia (HIT)
- Any thrombolytic therapy within two weeks of enrollment
- Target lesion(s) within a native vessel graft or synthetic graft
- Significant stenosis or occlusion of inflow not successfully treated before the index procedure
- Any evidence or history of intracranial or gastrointestinal bleeding or intracranial aneurysm
- Vulnerable subject populations (e.g., incarcerated or cognitively challenged adults)
- One or more of the following complications of the foot:
- Osteomyelitis that extends to the metatarsal bones.
- Gangrene involving the plantar skin of the forefoot, midfoot or heel
- Deep ulcer or large shallow ulcer (>3cm) involving the plantar skin of the forefoot, midfoot, or heel
- Any heel ulcer with/without calcaneal involvement
- Any wound with calcaneal bone involvement
- Wounds that are deemed to be neuropathic or non-ischemic in nature
- Wounds that require flap coverage or complete wound management for large soft tissue defect
- Congestive heart failure with a NYHA functional classification of III or higher
Angiographic exclusion criteria:
- More than 2 lesions to be treated with the investigational device; lesions located within 3 mm may be considered a single tandem lesion
- Clinical/angiographic complication (other than non-flow limiting dissections) attributed to a currently marketed device prior to introduction of the investigational device
- In-stent restenosis within the target lesion(s)
- Potentially unstable or flow-limiting dissection, type C or greater
- Clinical/angiographic evidence of distal embolization
- Inability to cross the proximal lesion vessel lumen with a guidewire (not subintimal)
