The main questions it aims to answer are:\n\nHow effective is liquid biopsy compared to the current standard of care (clinical surveillance and imaging) for early detection of MPNST development among people with NF1? Can liquid biopsy offer a cost-effective method for early detection of MPNST in people with NF1? Also, can liquid biopsy provide earlier detection that potentially leads to better outcomes? Also, can offering liquid biopsy improve access to care for people experiencing barriers to access (such as minority populations or people in rural areas)?\n\nAt baseline, participants will be asked to:\n\n* Complete surveys to provide their demographic and NF1-related health information.\n* Report whether or not they are experiencing MPNST-related symptoms.\n* Provide blood samples (15 mL blood total between three tubes, which is approximately one tablespoon).\n\nEvery six months during the five-year follow-up period, participants will be asked to:\n\n* Complete additional surveys to report whether or not they are experiencing MPNST-related symptoms and/or if they have been diagnosed with a new MPNST.\n* Provide an additional blood sample (10 mL blood total in one tube).\n\nIf diagnosed with an MPNST by their healthcare provider during the follow-up period, participants will be asked to:\n\n* Complete an additional survey regarding their diagnosis and symptoms.\n* Provide an additional blood sample (10 mL blood in one tube).\n* In parallel, the study team will request a sample of tumor tissue from the care provider, if available.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'The study population will be adults with NF1 who live in the United States.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 18 years and older (adults only)\n* Neurofibromatosis Type 1 (NF1) diagnosis (2021 Revised Diagnostic Criteria, PMID: 34012067)\n* History of plexiform neurofibroma (PN)\n* Able to read and understand English or Spanish\n* Live in the USA\n\nExclusion Criteria:\n\n* Are children (younger than 18 years old)\n* Do not have NF1\n* Have no evidence of PN\n* Are not able to read and understand English or Spanish'}, 'identificationModule': {'nctId': 'NCT06515860', 'acronym': 'NF1-TED', 'briefTitle': 'Neurofibromatosis Type 1 Tumor Early Detection Study', 'organization': {'class': 'OTHER', 'fullName': "Boston Children's Hospital"}, 'officialTitle': 'Observational Trial of Liquid Biopsy for Malignant Peripheral Nerve Sheath Tumor (MPNST) Among Participants With Neurofibromatosis Type 1', 'orgStudyIdInfo': {'id': '23-380'}, 'secondaryIdInfos': [{'id': '23-380', 'type': 'OTHER', 'domain': 'Dana Farber/Harvard Cancer Center IRB'}]}, 'armsInterventionsModule': {'interventions': [{'name': 'Liquid biopsy for MPNST development', 'type': 'DIAGNOSTIC_TEST', 'description': 'Participants will be asked to complete a blood sample (liquid biopsy) at baseline (15 mL, approximately 1 tablespoon) and every 6 months (10 mL) for the five-year follow-up period.'}]}, 'contactsLocationsModule': {'locations': [{'zip': '02115', 'city': 'Boston', 'state': 'Massachusetts', 'status': 'RECRUITING', 'country': 'United States', 'contacts': [{'name': 'David T Miller, MD, PhD', 'role': 'CONTACT', 'email': 'david.miller2@childrens.harvard.edu', 'phone': '617-355-8221'}, {'name': 'David T Miller, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': "Boston Children's Hospital", 'geoPoint': {'lat': 42.35843, 'lon': -71.05977}}], 'centralContacts': [{'name': 'David T Miller, MD, PhD', 'role': 'CONTACT', 'email': 'david.miller2@childrens.harvard.edu', 'phone': '617-355-8221'}, {'name': 'Aryani Pallerla, BS', 'role': 'CONTACT', 'email': 'aryani.pallerla@childrens.harvard.edu', 'phone': '6173554517'}], 'overallOfficials': [{'name': 'David T Miller, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': "Boston Children's Hospital"}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED', 'description': 'Investigators conducting the analysis at the end of the follow-up period will need access to IPD, but the plan to share IPD is not yet written.'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'David Miller', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR_INVESTIGATOR', 'investigatorTitle': 'Principal Investigator', 'investigatorFullName': 'David Miller', 'investigatorAffiliation': "Boston Children's Hospital"}}}}
