Image-Guided (68Ga-PSMA-11 PET/CT) Prostate Biopsy for the Diagnosis of Prostate Cancer in Men With Prior Negative/Inconclusive Biopsy
Recruiting
This early phase I trial studies how well an image-guided prostate biopsy using the imaging agent 68Ga-prostate-specific membrane antigen (PSMA)-11 with a positron emission tomography/computed tomography (PET/CT) scan works in diagnosing prostate cancer in men with a prior negative or inconclusive prostate biopsy. PSMA is a protein that is found on the surface of prostate cancer cells. 68Ga-PSMA-11 is made up of a substance that binds to PSMA on tumor cells, linked with a radioactive substance t... Read More

Adjuvant ctDNA-Adapted Personalized Treatment in Early Stage NSCLC (ADAPT-E)
Recruiting
In this study circulating tumor DNA (ctDNA) blood testing is used to detect the residual blood cancer. If residual cancer using this blood test is detected there may be at higher risk of having the cancer return. The study is going to test whether or not the number of circulating cancer cells detected in the blood can be reduced by administration durvalumab after the standard treatment if you are tested positive for the residual cancer.

Cardiotoxicity Assessment Through Comprehensive Heart Imaging to Predict Heart Failure
Recruiting
Anthracycline chemotherapies (e.g. doxorubicin, daunorubicin) are commonly given to treat pediatric cancer, and carry a risk of cardiotoxicity. Over the long term, children who receive these therapies have an increased risk of heart failure and early cardiovascular death. However, current strategies for identifying patients who are at risk prior to the development of significant changes in heart function are limited. This study will focus on imaging markers of cardiac injury and dysfunction with... Read More

Novel Serum Markers for Monitoring Response to Anti-Cancer Therapy
Recruiting
The purpose of this study is to measure the levels of serum proteins and other biomarkers in cancer patients and in patients suspected of having cancer. We believe that some of these markers may be useful for confirming the diagnosis or for selecting patients for specific types of cancer therapies. These markers may also help to predict response to therapy, relapse after therapy, and survival after therapy.

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.
