Solid Tumor Analysis for HLA Loss of Heterozygosity (LOH) and Apheresis for CAR T- Cell Manufacturing
NCT04981119
Recruiting
Objective: To collect information on how often a solid tumor cancer might lose the Human Leukocyte Antigen (HLA) by next generation sequencing and perform apheresis to collect and store an eligible participant's own T cells for future use to make CAR T-Cell therapy for their disease treatment. Design: This is a non-interventional, observational study to evaluate participants with solid tumors with a high risk of relapse for incurable disease. No interventional therapy will be administered on... Read More

A Study of 177Lu-FAP-2286 in Advanced Solid Tumors
NCT04939610
Recruiting
Fibroblast activation protein (FAP) is a cell surface protein that is highly expressed on the surface of cancer-associated fibroblasts (CAFs) present in the tumor microenvironment of most epithelial cancers, whereas limited expression of FAP is observed in normal tissues. In some cancers of mesenchymal origin, notably sarcoma and mesothelioma, FAP expression has also been observed on the tumor cells themselves. Given the restricted expression profile, FAP is a promising target for peptide-target... Read More

Prospective Evaluation Of High-Dose Systemic Methotrexate In Patients With Breast Cancer And Leptomeningeal Metastasis
NCT02422641
Recruiting
Management of leptomeningeal disease (LMD) in patients with metastatic breast cancer is an area of unmet clinical need. High-dose methotrexate (HD-MTX) is known to have activity against breast cancer and in contrast to other systemic chemotherapeutics, it penetrates the blood brain barrier, targets areas of poor cerebrospinal fluid flow, may penetrate bulky leptomeningeal disease, and provide treatment to systemic disease burden. While two retrospective studies have suggested activity of HD-MTX... Read More
