Stellate Ganglion Block for PTSD
Recruiting
Posttraumatic Stress Disorder (PTSD) is a debilitating condition that affects about 15% of Veterans. Current treatments for Veterans with PTSD include medications and psychological therapies that help to process and desensitize to traumatic events. While effective for many, these treatments do not work for all patients, and many may refuse them. Stellate Ganglion Block (SGB), established to treat pain and other conditions, has shown promise for PTSD: early small studies show it may work fast and... Read More

Prevention of Bleeding in Patients With Moderate and Severe Hemophilia A Playing Sports: A Comparison Between Factor VIII and Emicizumab Prophylaxis
Recruiting
Hemophilia A (HA) is a genetic bleeding disorder resulting from a deficiency or absence of factor VIII (FVIII), which is necessary in the clotting process. This disorder occurs mostly in males and in severe cases causes frequent bleeding episodes in joints and muscles which can lead to progressive damage that affects mobility and quality of life. Prophylactic FVIII administered intravenously every other day has been the standard of care treatment for HA for the past few decades.

A Clinical Trial of Intravenous Lidocaine After Spinal Surgery to Prevent Delirium and Reduce Pain
Recruiting
Postoperative delirium is one of the most frequent adverse events following elective non-cardiac surgery and is associated with cognitive impairment at discharge, as well as in-hospital and long-term mortality, however, despite being a well-recognized problem there is a dearth of effective interventions for prevention and management. A modifiable risk factor associated with postoperative delirium is poor postoperative pain control, and by improving the pain regimen the investigators may be able... Read More

Thymus Regeneration, Immunorestoration, and Insulin Mitigation Extension Trial
Recruiting
The TRIIM-X trial is an expanded pilot clinical study that will evaluate a personalized combination treatment regimen for thymus regeneration. The thymus is a part of the immune system that declines markedly with age, and regenerating it may prevent or reverse key aspects of immunosenescence (immune system aging) and potentially prevent or reverse key parts of the aging process more generally. The study will evaluate biomarkers for epigenetic aging and immunosenescence, as well as evaluate estab... 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.
