Extremely Hypofractionated Intensity Modulated Stereotactic Body Radiotherapy for the Treatment of Prostate Cancer With Rising PSA After Radical Prostatectomy
Recruiting
This phase II trial investigates the effect of extremely hypofractionated intensity modulated stereotactic body radiotherapy in treating patients with prostate cancer that has rising prostate specific antigen (PSA) after radical prostatectomy. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Hypofracti... Read More

Cobimetinib in Refractory Langerhans Cell Histiocytosis (LCH), and Other Histiocytic Disorders
Recruiting
This is a research study of a drug called cobimetinib in children and adults diagnosed with Langerhans cell histiocytosis (LCH), and other histiocytic disorders that has returned or does not respond to treatment. Cobimetinib blocks activation of a protein called Mitogen-activated protein kinase (MEK) that is part of incorrect growth signals in histiocytosis cells.

Study to Evaluate the Pharmacokinetics and Safety of Pralatrexate in Patients With Advanced Solid Tumor or Hematological Malignancy and Either Normal Hepatic Function or Mild, Moderate, or Severe Hepatic Impairment
Recruiting
This purpose of this study is to help to evaluate the pharmacokinetic (PK) profile of pralatrexate when administered to patients with various degrees of hepatic impairment and to evaluate the safety and establish the dosing recommendations for pralatrexate administered once weekly for 6 weeks of every 7-week treatment cycle in patients with hepatic impairment. Pharmacokinetics (or PK) is the study of how your body absorbs, breaks down, and removes a study drug.

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.
