A secondary outcome measure is whether cavitation-related changes occur in tissue perfusion in the treated limb and wound measured by ultrasound perfusion imaging and skin flow.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Known history of unilateral or bilateral PAD diagnosed by reduced ankle-brachial index (\\<0.9) or non-compressible vessels\n* Diagnosis of CLI (Rutherford class IV-VI), and a non-healing ischemic ulcer defined as no change in the prior 3 months.\n\nExclusion Criteria:\n\n* Major medical illness other than PAD affecting the limb (muscle disease, blood diseases that influence flow or rheology, severe heart failure \\[NYHA class IV\\]).\n* Pregnant or lactating females\n* Hypersensitivity to any ultrasound contrast agent or to polyethylene glycol (PEG, macrogol).\n* Hemodynamic instability (hypotension with systolic BP \\<90 mm Hg, need for vasopressors).\n* Expected amputation or revascularization procedure within the ensuing 1 month.'}, 'identificationModule': {'nctId': 'NCT05749250', 'briefTitle': 'Ultrasound Cavitation Therapy for CLI', 'organization': {'class': 'OTHER', 'fullName': 'University of Virginia'}, 'officialTitle': 'Ultrasound Cavitation for Treatment of Non-healing Ulcers in Critical Limb Ischemia', 'orgStudyIdInfo': {'id': 'HSR220344'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Cavitation therapy', 'description': 'Subjects treated with cavitation energy', 'interventionNames': ['Device: Acoustic cavitation of ultrasound enhancing agents']}, {'type': 'NO_INTERVENTION', 'label': 'Control', 'description': 'Control subjects not treated with cavitation energy'}], 'interventions': [{'name': 'Acoustic cavitation of ultrasound enhancing agents', 'type': 'DEVICE', 'description': 'Cavitation therapy', 'armGroupLabels': ['Cavitation therapy']}]}, 'contactsLocationsModule': {'locations': [{'zip': '22908', 'city': 'Charlottesville', 'state': 'Virginia', 'status': 'RECRUITING', 'country': 'United States', 'contacts': [{'name': 'Jonathan Lindner, MD', 'role': 'CONTACT', 'email': 'jlindner@virginia.edu', 'phone': '434-297-9442'}], 'facility': 'University of Virginia', 'geoPoint': {'lat': 38.02931, 'lon': -78.47668}}], 'centralContacts': [{'name': 'Jonathan Lindner, MD', 'role': 'CONTACT', 'email': 'jlindner@virginia.edu', 'phone': '434 297-9442'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Virginia', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Professor of Medicine, Cardiovascular Medicine', 'investigatorFullName': 'Jonathan Lindner, MD', 'investigatorAffiliation': 'University of Virginia'}}}}
