Since the surgical procedure is independent of the population a single center study is applied. A double-blind study is not possible considering the implantation procedure with the surgeon always knowing if the device is set. Therefore, the study is designed to be non-randomized and non-blinded as a pilot trial.\n\nTo reduce bias and other influences of single surgeon skills a principal investigator and one investigator are part of the clinical study. Further, subjects with previous treatments such as Pillar implant or previous airway surgery other than nasal, adenoid, tonsil or UPPP are excluded from the clinical study. A double-blind study is not possible considering the implantation procedure with the surgeon always knowing if the device is set. Therefore, the study is designed to be non-randomized and non-blinded as a pilot trial.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* • Socially disturbing snoring and obstructive sleep apnea syndrome with AHI≥10/h\n\n * Predominantly retropalatal obstructions established either by:\n * Drug-induced sedation nasendoscopy\n * or ApneaGraph ≥60% (optional)\n * or successful application of the Velumount palatal device (optional)\n * Findings for predominantly retropalatal obstructions in ENT-examination:\n * No tonsils or tonsils grade I\n * Normal finding of larynx and tongue base, no omega-shaped epiglottis\n * No lingual tonsil hypertrophy\n * ASA (American Society of Anaesthesiology, 1963) classes I or II\n * Body mass index (BMI) \\< 30 kg/m2\n * Age \\> 18 yrs\n * Fix bed partner\n * Ability to read and understand the patient's information\n\nExclusion Criteria:\n\n* • Previous Pillar implants\n\n * Medartis palatinal implant (from previous phase I study)\n * Previous airway surgery other than nasal, adenoid, tonsil or UPPP\n * Presence of other sleep disorders\n * Psychiatric disorders\n * Neurological disorders (e.g. Cerebrovascular injury)\n * Dysmorphia of the cranial skeleton\n * Pregnancy or breastfeeding\n * Known hypersensitivity to nitinol\n * Participation in another clinical study\n * Recurrent tonsillitis with prescription of antibiotics during the last 2 years (≥3x/year)\n * Omega-shaped epiglottis\n * Lingual tonsil hypertrophy\n * Kinking of the internal carotid artery"}, 'identificationModule': {'nctId': 'NCT03640793', 'briefTitle': 'Prospective Evaluation of a Palato-Pharyngeal Implant System (PPIS) Obstructive Sleep Apnea Syndrome (OSAS)', 'organization': {'class': 'INDUSTRY', 'fullName': 'Medartis AG'}, 'officialTitle': 'Prospective Evaluation of a Palato-Pharyngeal Implant System (PPIS) for the Treatment of Snoring and Obstructive Sleep Apnea Syndrome (OSAS): a Pilot Study', 'orgStudyIdInfo': {'id': 'P15214'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Single center, prospective, non-randomized, non-blinded study', 'description': 'Implantation of 6 PPIS implants in each patient', 'interventionNames': ['Device: Implantation']}], 'interventions': [{'name': 'Implantation', 'type': 'DEVICE', 'description': 'Implantation of 6 PPIS implants', 'armGroupLabels': ['Single center, prospective, non-randomized, non-blinded study']}]}, 'contactsLocationsModule': {'locations': [{'zip': '4410', 'city': 'Basel', 'state': 'Basel-Landschaft', 'country': 'Switzerland', 'facility': 'Kantonsspital Liestal'}], 'overallOfficials': [{'name': 'Kurt Tschopp, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Kantonsspital Liestal'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Medartis AG', 'class': 'INDUSTRY'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
