Lymphoma is a cancer that starts in the blood cells that fight infection. There are several types of lymphoma.

The study drug is in testing and has not been approved for sale. This is the first time SGN -35C will be used in people.\n\nThis study will test the safety of SGN-35C in participants with lymphoma. It will also study the side effects of this drug. A side effect is anything a drug does to the body besides treating the disease.\n\nThis study will have three parts. Parts A and B of the study will find out the best dose and dosing schedule for SGN-35C. Part C will use the dose found in parts A and B to find out how safe SGN-35C is and if it works to treat select lymphomas.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Tumor type\n* For dose escalation and back fill and dose optimization (Parts A and B):\n\n * Participants with a histologically confirmed lymphoid neoplasm who in the judgement of the investigator have no appropriate standard therapy available at the time of enrollment and are a candidate for PF-08046044/SGN- 35C treatment.

Exceptions are malignancies with a negligible risk of metastasis or death\n* Active central nervous system (CNS) disease related to the underlying malignancy. Participants with a history of CNS disease related to the underlying malignancy are allowed if prior CNS disease has been treated and the participant is clinically stable (defined as not currently receiving steroid treatment for symptoms related to cerebral/meningeal disease and with no ongoing related AE).\n* Received previous ASCT infusion \\<12 weeks prior to the first dose of SGN-35C.\n* Previous allogeneic stem cell transplant (SCT) if they meet any of the following criteria:\n\n * \\<100 days from allogeneic SCT. Participants ≥100 days from allogeneic SCT who are stable without immunosuppressive therapy for at least 12 weeks are permitted.\n * Active acute or chronic graft-versus-host disease (GVHD) or receiving immunosuppressive therapy as treatment for or prophylaxis against GVHD.\n* History of clinically significant GI bleeding, intestinal obstruction, or GI perforation within 6 months of initiation of trial treatment.'}, 'identificationModule': {'nctId': 'NCT06254495', 'briefTitle': 'A Safety Study of PF-08046044/SGN-35C in Adults With Advanced Cancers', 'organization': {'class': 'INDUSTRY', 'fullName': 'Seagen Inc.'}, 'officialTitle': 'A Phase 1, Open-label Study to Evaluate PF-08046044/SGN-35C in Adults With Advanced Malignancies.', 'orgStudyIdInfo': {'id': 'SGN35C-001'}, 'secondaryIdInfos': [{'id': 'C5801001', 'type': 'OTHER', 'domain': 'Alias Study Number'}, {'id': '2023-505813-26-00', 'type': 'REGISTRY', 'domain': 'CTIS (EU)'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'PF-08046044/SGN-35C', 'description': 'PF-08046044/SGN-35C Monotherapy', 'interventionNames': ['Drug: PF-08046044/SGN-35C']}], 'interventions': [{'name': 'PF-08046044/SGN-35C', 'type': 'DRUG', 'description': 'Given into the vein (IV; intravenously)', 'armGroupLabels': ['PF-08046044/SGN-35C']}]}, 'contactsLocationsModule': {'locations': [{'zip': '91010', 'city': 'Duarte', 'state': 'California', 'country': 'United States', 'facility': 'City of Hope (City of Hope National Medical Center, City Of Hope Medical Center)', 'geoPoint': {'lat': 34.13945, 'lon': -117.97729}}, {'zip': '91010', 'city': 'Duarte', 'state': 'California', 'country': 'United States', 'facility': 'IP Address: City of Hope Investigational Drug Services(IDS)', 'geoPoint': {'lat': 34.13945, 'lon': -117.97729}}, {'zip': '94143', 'city': 'San Francisco', 'state': 'California', 'country': 'United States', 'facility': 'University of California, San Francisco Medical Center', 'geoPoint': {'lat': 37.77493, 'lon': -122.41942}}, {'zip': '33146', 'city': 'Coral Gables', 'state': 'Florida', 'country': 'United States', 'facility': 'Sylvester Comprehensive Cancer Center- The Lennar Foundation Medical Center', 'geoPoint': {'lat': 25.72149, 'lon': -80.26838}}, {'zip': '33442', 'city': 'Deerfield Beach', 'state': 'Florida', 'country': 'United States', 'facility': 'University of Miami Hospital and Clinics -
