Solid Tumor Analysis for HLA Loss of Heterozygosity (LOH) and Apheresis for CAR T- Cell Manufacturing
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

Prospective Evaluation Of High-Dose Systemic Methotrexate In Patients With Breast Cancer And Leptomeningeal Metastasis
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

TrialNet Pathway to Prevention of T1D
Recruiting
Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T... Read More

Chronic Subdural Hematoma Treatment With Embolization Versus Surgery Study
Recruiting
The goal of this clinical trial is to test in moderately symptomatic chronic subdural hematoma (CSDH) patients if middle meningeal artery embolization (MMAE) can be used as an alternative to conventional open surgery. The main questions it aims to answer are: * Compared to open conventional surgery, does MMAE reduce the need for rescue surgery or deaths? * What is the safety of MMAE and conventional open surgery in these patients? Participants will be asked to: * Share their medical history a... Read More

Ruxolitinib With and Without CTLA-4 Ig Abatacept for the Prophylaxis of Graft-Versus-Host Disease and Cytokine Release Syndrome After T-cell Replete Haploidentical Peripheral Blood Hematopoietic Cell Transplantation
Recruiting
Allogeneic hematopoietic cell transplantation (HCT) is one of the only curative intent therapies available for hematologic malignancies. HLA-matched sibling donors have historically offered the best clinical results but are unavailable for the majority of patients, while most patients do have readily available haploidentical donors. One of the risks of a haploidentical HCT is graft vs. host disease (GVHD), but it is difficult to reduce the incidence of GVHD without compromising the graft vs. leu... Read More

Rural Colon Cancer Screening Toolkit Intervention
Recruiting
Less than half of all positive fecal immunochemical testing (FIT)s are followed-up by colonoscopy, thus limiting the full potential of colorectal cancer (CRC) screening to reduce mortality. Given the need for coordination in order to achieve high rates of follow-up, multilevel approaches are needed. Such approaches could be particularly beneficial in communities and populations that experience cancer disparities and have fewer specialty providers, but most data focuses on large systems or urban...
