With improvement in treatment options, rates of leptomeningeal disease are increasing and currently found in up to 9% of EGFR mutant NSCLC.\n\nSystemic therapy may be more effective if it can target the correct molecular aberration. The molecular characterization of central nervous system disease may differ from disease outside of the central nervous system. The aim of this pilot trial is to evaluate for molecular differences between cerebral spinal fluid (CSF) and blood circulating tumor DNA (ctDNA) through the use of ddPCR and BC Cancer NGS panel molecular testing.', 'detailedDescription': 'The aim of this pilot trial is to evaluate the concordance/discordance of molecular profiling of CSF and plasma ctDNA after the development of leptomeningeal disease in EGFR mutant NSCLC. Patients with EGFR mutant NSCLC who develop leptomeningeal disease on a first, second or third generation tyrosine kinase inhibitor are potentially eligible for this clinical trial.\n\nThis is a prospective pilot study designed to accrue 10 patients. Baseline MRI brain and spine must be completed prior to enrolment to insure that a lumbar puncture can be completed safely. All eligible subjects will be consented for ddPCR and Canexia Follow It plasma and CSF based molecular testing. Patients will have baseline information collected and will complete baseline quality of life (QoL) questionnaires. QoL questionnaires will be obtained every 12 weeks +/- 2 weeks and survival will be measured through chart review. There will be no treatment intervention; however we will collect information on treatment received after enrolment in trial. Volume of leptomeningeal disease will be scored by number of gadolinium enhancing sites in 8 predetermined locations.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Subject age is greater than or equal to 18 years at the time of signature of informed consent.\n* Histologically or cytologically confirmed metastatic EGFR mutant NSCLC.\n* Leptomeningeal disease based on brain MRI or CSF cytology.\n* ECOG 0-3.\n* Life expectancy of at least 8 weeks.\n* Adequate hematologic and end organ function for testing.\n* Ability to give informed consent for the study procedures defined in this protocol.\n\nExclusion Criteria:\n\n* Inability to undergo a lumbar puncture due to thrombocytopenia, bleeding disorders, as well as inability to cooperate or consent to procedure.\n* Subjects who are otherwise felt by the treating clinician to be unfit to proceed with this protocol.\n* MRI spine demonstrating spinal leptomeningeal disease preventing a safe lumbar puncture.'}, 'identificationModule': {'nctId': 'NCT05257967', 'briefTitle': 'CSF Analysis in EGFR Mutant Non-Small Cell Lung Cancer with Leptomeningeal Disease', 'organization': {'class': 'OTHER', 'fullName': 'British Columbia Cancer Agency'}, 'officialTitle': 'CSF Liquid Biopsy Based Characterization of Leptomeningeal Disease in EGFR Mutant Non-Small Cell Lung Cancer', 'orgStudyIdInfo': {'id': 'LUEGFRLM'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Experimental arm', 'description': 'ddPCR and BC Cancer NGS panel completed on cerebral spinal fluid and blood circulating tumor DNA', 'interventionNames': ['Diagnostic Test: Lumbar puncture and Phlebotomy']}], 'interventions': [{'name': 'Lumbar puncture and Phlebotomy', 'type': 'DIAGNOSTIC_TEST', 'description': 'Sampling of cerebral spinal fluid and plasma.', 'armGroupLabels': ['Experimental arm']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'V5Z4E6', 'city': 'Vancouver', 'state': 'British Columbia', 'status': 'RECRUITING', 'country': 'Canada', 'contacts': [{'name': 'Cheryl Ho, MD', 'role': 'CONTACT', 'phone': '604-877-6000'}], 'facility': 'BC Cancer', 'geoPoint': {'lat': 49.24966, 'lon': -123.11934}}], 'centralContacts': [{'name': 'Cheryl Ho, MD', 'role': 'CONTACT', 'email': 'cho@bccancer.bc.ca', 'phone': '604.877.6000'}, {'name': 'Barbara Melosky, MD', 'role': 'CONTACT', 'phone': '604.877.6000'}], 'overallOfficials': [{'name': 'Cheryl Ho, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'BC Cancer'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'British Columbia Cancer Agency', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Prinicipal Investigator', 'investigatorFullName': 'Cheryl', 'investigatorAffiliation': 'British Columbia Cancer Agency'}}}}
