The most common side effects of ICI are immune-related adverse events which can affect any organ or system in the body. Recently, concerns have also risen about cardiovascular effects of ICI. Retrospective studies showed an 4-5 times increased risk of developing an arterial thromboembolic event.\n\nThe mechanisms driving the ICI-associated risks of arterial thromboembolic events such as myocardial infarction and stroke, are unclear. Since the risk of a thromboembolism appears to be increased already during the first months after initiation of ICI, immune-related hypercoagulability or (autoimmune) antiphospholipid antibodies may play a role, but data to support this are lacking. The longer-term risk of arterial thromboembolism may be predominantly driven by (accelerated) atherosclerosis, a chronic low-grade inflammatory disease of the larger arteries. Therefore, this study evaluates the effect of ICI on progression of coronary non-calcifid plaque volume by using computed tomography angiography (CCTA).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '50 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Adult male or female subjects are eligible for study participation if they have a confirmed cancer diagnosis', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients with confirmed diagnosis of the following tumor types, any stage: esophageal, gastric or junction cancer, colorectal cancer, non-small cell lung carcinoma, melanoma, renal cell carcinoma\n* Prior to start of new therapy (i.e. immune checkpoint inhibitor, chemotherapy or follow-up in case of esophageal cancer)\n* Age ≥ 50 years\n\nExclusion Criteria:\n\n* ICI therapy in previous 12 months\n* Suspected or confirmed viral, fungal, or bacterial infectious disease\n* Use of immunosuppressive therapy prior to ICI start\n* Estimated glomerular filtration rate (eGFR) \\<30 mL/min/1.73m2\n* Known allergy to iodinated contrast agents\n* Atrial fibrillation'}, 'identificationModule': {'nctId': 'NCT06519292', 'acronym': 'ITHACA', 'briefTitle': 'Immune Checkpoint Inhibitor Associated Cardiovascular Adverse Events in Patients With Cancer', 'organization': {'class': 'OTHER', 'fullName': 'Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA)'}, 'officialTitle': 'Immune Checkpoint Inhibitor Associated Cardiovascular Adverse Events in Patients With Cancer', 'orgStudyIdInfo': {'id': 'NL82446.018.22'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'ICI group', 'description': 'Patients that receive immune checkpoint inhibitors', 'interventionNames': ['Diagnostic Test: Coronary computed tomography angiography (CCTA) at baseline', 'Diagnostic Test: Coronary computed tomography angiography (CCTA) after 1 year']}, {'label': 'Non-ICI group', 'description': 'Patients with similar malignancies, who do not receive immune checkpoint inhibitors', 'interventionNames': ['Diagnostic Test: Coronary computed tomography angiography (CCTA) at baseline', 'Diagnostic Test: Coronary computed tomography angiography (CCTA) after 1 year']}], 'interventions': [{'name': 'Coronary computed tomography angiography (CCTA) at baseline', 'type': 'DIAGNOSTIC_TEST', 'description': 'Detailed imaging of coronary arteries', 'armGroupLabels': ['ICI group', 'Non-ICI group']}, {'name': 'Coronary computed tomography angiography (CCTA) after 1 year', 'type': 'DIAGNOSTIC_TEST', 'description': 'Detailed imaging of coronary arteries', 'armGroupLabels': ['ICI group', 'Non-ICI group']}]}, 'contactsLocationsModule': {'locations': [{'zip': '1105AZ', 'city': 'Amsterdam', 'state': 'North Holland', 'status': 'RECRUITING', 'country': 'Netherlands', 'contacts': [{'name': 'A Strijdhorst', 'role': 'CONTACT', 'email': 'a.strijdhorst@amsterdamumc.nl', 'phone': '+31 205665975'}], 'facility': 'Amsterdam UMC', 'geoPoint': {'lat': 52.37403, 'lon': 4.88969}}], 'centralContacts': [{'name': 'A Strijdhorst', 'role': 'CONTACT', 'email': 'a.strijdhorst@amsterdamumc.nl', 'phone': '+31 205665975'}], 'overallOfficials': [{'name': 'H.W.M. van Laarhoven, Prof. Dr.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'secretariaat.oncologie@amsterdamumc.nl'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Hanneke W.
