Single-tracer Multiparametric PET Imaging
Recruiting
The overarching goal of this project is to develop and evaluate a single-tracer multiparametric positron emission tomography (PET) imaging solution for simultaneous imaging of blood flow and glucose metabolism using 18F-fluorodeoxyglucose (FDG) alone. The investigators working hypothesis is that quantitative blood flow can be extracted from dynamic 18F-FDG PET data by use of tracer kinetic modeling, in addition to glucose metabolism that 18F-FDG is conventionally used for.

Intracerebroventricular Administration of CD19-CAR T Cells (CD19CAR-CD28-CD3zeta-EGFRt-expressing Tn/Mem T-lymphocytes) for the Treatment of Central Nervous System Lymphoma
Recruiting
This phase I trial tests the safety, side effects, and best dose of intracerebroventricularly (ICV) administered CD19-chimeric antigen receptor (CAR) T cells in treating patients with central nervous system (CNS) lymphoma. CAR T cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein,... Read More

Leflunomide in Combination With Steroids for the Treatment of Acute Graft-versus-Host Disease After Donor Stem Cell Transplant for Hematologic Malignancies
Recruiting
This phase I trial tests the safety and side effects of leflunomide in combination with steroids in treating patients with acute graft versus host disease who have undergone done stem cell transplant for blood cancers (hematologic malignancies). Sometimes the transplanted cells from a donor can attack the body's normal cells (called graft-versus-host disease). Leflunomide and steroids are immunosuppressive drugs that work in different ways to lower the body's immune response so that the new dono... Read More

Kaiser Permanente houses over 6,000 physicians in southern California and it is also one of the largest research centers on the state. On its clinical trial division, Kaiser Permanente conducts clinical trials of almost every specialty funded by pharmaceutical companies, government, and foundations.
The Cedars-Sinai Medical Center located in Los Angeles is one of the largest research centers owned and operated by a private hospital in the United States. Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.
There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.
Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.
In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.
Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future. The following lists of trials are broken down by condition, and to find a specific clinical trial in your area click through to clinicaltrials.gov.
