An ideal injectable would not impair the fibroelastic property of the vocal fold tissues and would integrate within the tissue of the vocal fold. Since Renuva has the property of stimulating adipogenesis by using growth factor and collagen, the investigators believe it could represent a good option in terms of safety and efficacy for vocal fold augmentation.\n\nThis study will assess the safety and efficacy of Renuva as a vocal fold injectable to treat glottic insufficiency.', 'detailedDescription': 'Background/Significance:\n\nVocal cord injection augmentation is commonly used to treat glottal insufficiency. Various materials are used for injection augmentation including autologous fat, hyaluronic acid, collagen, carboxymethylcellulose, and calcium hydroxyapatite. However, all of the current injection choices have individual limitations such as temporary effect, unpredictability due to variable resorption by the body, unfavorable mechanical properties, and challenging handling attributes. Hence, there is a need for a more ideal injection augmentation substance that is biocompatible, nonimmunogenic, able to traverse small gauge needles, easy to use, and facilitates long term or permanent effect when desired.\n\nIntervention:\n\nUnilateral injection augmentation with allograft adipose matrix injectable. Renuva ®, is commonly used as in injectable material in plastic surgery for treatment of small cosmetic irregularities. The injectable stimulates adipogenesis using key matrix proteins including collagen IV, collagen VI, FGF-2, and VEGF. The injectable does not contain any lipids, cellular fragments, or DNA content. In vitro and in vivo demonstrate that the injectable can stimulate adipose tissue generation. Given this important quality, allograft adipose matrix may provide vocal fold bulk for a longer period of time with favorable viscoelastic properties which would make it a desirable agent for vocal fold augmentation.\n\nObjective:\n\nAssess the safety profile and efficacy of allograft adipose matrix for use in injection augmentation Study Design: Single arm prospective clinical trial.\n\nMethods:\n\n50 patients with glottal insufficiency will be enrolled to receive vocal fold augmentation injection using an Allograft adipose matrix, commercially available as Renuva ® over a 24 months recruitment period.\n\nStudy endpoints:\n\nPrimary study endpoint will be the completion of 12 months of follow up post injection with safety monitoring. Secondary endpoints will include patient reported outcome measures (VHI, VFI, DI and EAT-10), blinded Cape-V voice assessment by experts and laryngeal videostroboscopy blinded assessment with the mVali tool.\n\nPlan for analysis:\n\nThe study cohort will be analyzed via descriptive statistics of the primary outcome (safety) via incidence of both minor and major adverse events. Non-parametric statistics (Wilcoxon signed-rank test) will be used for comparisons of patient reported outcome measures and blinded evaluations of voice and videostroboscopy endpoints from post-intervention time points to pre-intervention baseline.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* • Age ≥ 18 years old\n\n * Unilateral vocal fold immobility with glottal insufficiency present for at least 2 weeks from onset\n * Willingness to partake in study and follow-up as documented by signed informed consent\n\nExclusion Criteria:\n\n* History of allergy/hypersensitivity to lidocaine or amide-based anesthetics\n* Pregnancy\n* Active infection or inflammation in the larynx (presence of acute laryngeal infection caused by bacteria/virus or fungus)\n* Comorbid known laryngeal conditions including but not limited to vocal fold scar, vocal tremor, laryngeal dystonia, etc. that would warrant other interventions for optimal treatment\n* History of laryngeal surgery\n* Life expectancy of less than 6 months'}, 'identificationModule': {'nctId': 'NCT04700566', 'briefTitle': 'Allograft Adipose Injectable for Vocal Fold Paralysis', 'organization': {'class': 'OTHER', 'fullName': 'University of Southern California'}, 'officialTitle': 'Safety and Efficacy of Allograft Adipose Matrix Injectable for Glottal Insufficiency', 'orgStudyIdInfo': {'id': 'HS-19-00876'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Injection of Renuva Allograft adipose matrix in vocal fold', 'description': 'Injection of Renuva Allograft Adipose matrix in the vocal fold for vocal fold medialization and treatment of glottal insufficiency', 'interventionNames': ['Biological: Renuva Allograft Adipose Matrix']}], 'interventions': [{'name': 'Renuva Allograft Adipose Matrix', 'type': 'BIOLOGICAL', 'description': 'Injection of Renuva Allograft adipose Matrix in the vocal fold for vocal fold medialization and treatment of glottal insufficiency', 'armGroupLabels': ['Injection of Renuva Allograft adipose matrix in vocal fold']}]}, 'contactsLocationsModule': {'locations': [{'zip': '90033', 'city': 'Los Angeles', 'state': 'California', 'status': 'RECRUITING', 'country': 'United States', 'contacts': [{'name': "Karla O'Dell", 'role': 'CONTACT', 'email': 'kodell@usc.edu', 'phone': '323-442-5790'}, {'name': 'Michael Johns', 'role': 'CONTACT', 'email': 'michael.johna@med.usc.edu', 'phone': '3234425790'}], 'facility': 'University of Southern California', 'geoPoint': {'lat': 34.05223, 'lon': -118.24368}}], 'centralContacts': [{'name': "Karla O'Dell, MD", 'role': 'CONTACT', 'email': 'karla.odell@med.usc.edu', 'phone': '18008722273'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Southern California', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Assistant Professor', 'investigatorFullName': "Karla O'Dell", 'investigatorAffiliation': 'University of Southern California'}}}}
