This pilot study will evaluate the Safety and Efficacy of Negative Pressure Neck Therapy (NPNT) in up to 10 healthy participants. Participants will undergo 2 separate home sleep apnea tests (HSAT) approximately 1 week apart and will be randomly assigned to wear the NPNT device at either night 1 or night 2 of HSAT. Participation will include 5 on-site visits and 1 phone call over approximately 1 month.', 'detailedDescription': "Purpose: To determine the safety and efficacy of the Negative Pressure Neck Therapy (NPNT) in Healthy Participants.\n\nNegative pressure neck therapy (NPNT) uses a self-contained, non-invasive, external device to apply a gentle, outward pulling effect around the neck's surface.\n\nHypothesis: Given the exploratory nature and small sample size no formal hypothesis testing will be conducted\n\nObjectives:\n\nPrimary Objective:\n\n1\\. To determine if NPNT can effectively reduce the number of apnea-hypopnea index (AHI) events (sleep disorder breathing events) in healthy participants.\n\nSecondary Objectives:\n\n1. To determine the tolerability of the NPNT\n2. To determine the duration of time required for acclimating to the device\n3. To determine the NPNT parameters (optimal device fit) based on participant characteristics.\n4. To collect feedback from participants regarding the device use, comfort, fit, function, usability, etc.\n\nSafety and Efficacy Objectives:\n\n1. To evaluate the safety and effectiveness of NPNT\n2. To assess potential side effects of NPNT."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '19 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Body mass index ≤42 kg/m2\n* Able to speak, read, and write English\n\nExclusion Criteria:\n\n* Known sleep disorder such as Obstructive Sleep Apnea (OSA), narcolepsy, restless leg syndrome, idiopathic hypersomnolence or chronic insomnia\n* No previous surgery, injury, or radiation to the neck\n* Excessive hair or beard in the area of the neck, and/or unwillingness to shave that area for the duration of this study\n* Inflammatory skin condition, such as acne or eczema in the neck area\n* Known silicone allergy\n* Night shift work because of irregular sleep-wake cycles\n* Excessive alcohol intake, defined as that leading to interference with work, home life, or the ability to optimally perform normal everyday duties and tasks\n* Use of illicit drugs currently or within the past 5 years\n* Serious pulmonary disease\n* Use of home oxygen or oxygen saturation \\<94%\n* Cancer that has been in remission for less than one year\n* Previous surgery for peripheral arterial disease'}, 'identificationModule': {'nctId': 'NCT07301567', 'briefTitle': 'Pilot Study of Negative Pressure Neck Therapy (NPNT)', 'organization': {'class': 'OTHER', 'fullName': 'University of British Columbia'}, 'officialTitle': 'A Proof-of-concept Pilot Study to Determine the Safety and Effectiveness of the Negative Pressure Neck Therapy (NPNT) in Healthy Participants.', 'orgStudyIdInfo': {'id': 'H25-02563'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Group 1', 'description': 'One night of Home sleep apnea testing (HSAT) with Negative Pressure Neck Therapy (NPNT) intervention, followed by 7 night washout, then one night of HSAT only', 'interventionNames': ['Device: Negative Pressure Neck Therapy (NPNT)']}, {'type': 'EXPERIMENTAL', 'label': 'Group 2', 'description': 'One night of HSAT only, followed by 7 night washout, then one night of HSAT with NPNT intervention.', 'interventionNames': ['Device: Negative Pressure Neck Therapy (NPNT)']}], 'interventions': [{'name': 'Negative Pressure Neck Therapy (NPNT)', 'type': 'DEVICE', 'description': 'Negative pressure neck therapy (NPNT) is a self-contained, non-invasive, soft, flexible, external neck collar', 'armGroupLabels': ['Group 1', 'Group 2']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'V5Z 1M9', 'city': 'Vancouver', 'state': 'British Columbia', 'country': 'Canada', 'contacts': [{'role': 'CONTACT', 'phone': '6048754122'}], 'facility': 'Centre for Lung Health', 'geoPoint': {'lat': 49.24966, 'lon': -123.11934}}, {'zip': 'V6T 2B5', 'city': 'Vancouver', 'state': 'British Columbia', 'country': 'Canada', 'contacts': [{'role': 'CONTACT', 'phone': '6048754122'}], 'facility': 'Leon Judah Blackmore Centre for Sleep Disorders', 'geoPoint': {'lat': 49.24966, 'lon': -123.11934}}], 'centralContacts': [{'name': 'Research Manager', 'role': 'CONTACT', 'email': 'Shelley.Abercromby@vch.ca', 'phone': '6048754111', 'phoneExt': '62500'}], 'overallOfficials': [{'name': 'John A Fleetham, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'VCHA/UBC'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED', 'description': 'This is a pilot study, so only IPD used in the results publication may be shared in the future.'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of British Columbia', 'class': 'OTHER'}, 'collaborators': [{'name': 'Vancouver Coastal Health Research Institute', 'class': 'OTHER'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Professor', 'investigatorFullName': 'John Fleetham', 'investigatorAffiliation': 'University of British Columbia'}}}}
