VIRtual Versus UsuAL In-office Care for Multiple Sclerosis (VIRTUAL-MS)
Recruiting
The current standard of outpatient MS care depends on in-clinic visits, but MS patients face many barriers to accessing this care. These barriers include those resulting from the disease itself, such as physical limitations, driving restrictions and financial limitations, and they are further compounded by an overall shortage of neurologists. Furthermore, MS care has a significant economic impact, with the estimated indirect and direct costs for treating MS in the US estimated to be \> $85.4 bil... Read More

TEAMS R34 #1 After-Action Reviews in Child Welfare Services
Recruiting
This project proposes to improve successful mental health service linkage in Child Welfare Services (CWS) by adapting and testing the After Action Review (AAR) team effectiveness intervention to augment the Child Family Team (CFT) services intervention. Despite being both required and a collaborative approach to service planning, CFT meetings are implemented with questionable fidelity and consistency, rarely including children and families as intended.

A Single-Arm Phase II Study of Neoadjuvant Intensified Androgen Deprivation (Leuprolide and Abiraterone Acetate) in Combination With AKT Inhibition (Capivasertib) for High-Risk Localized Prostate Cancer With PTEN Loss
Recruiting
The purpose of this study is to learn about how an investigational drug intervention completed before doing prostate surgery (specifically, radical prostatectomy with lymph node dissection) may help in treatment of high risk localized prostate cancers that are most resistant to standard treatments. This is a phase II research study. For this study, capivasertib, the study drug, will be taken with intensified androgen deprivation drugs (iADT; abiraterone and leuprolide) prior to radical prostatec... Read More

The Cardiovascular Consequences of Sleep Apnea Plus COPD (Overlap Syndrome)
Recruiting
Major progress has been made in the area of cardiovascular disease, but we believe that further progress will involve mechanistically addressing underlying respiratory causes including chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA). The most common cause of death in COPD is cardiovascular, although mechanisms are unknown. OSA has been associated with major neurocognitive and cardiovascular sequelae, the latter likely a function of autonomic nervous system abnormal... Read More

Limiting AAA With Metformin (LIMIT) Trial
Recruiting
In this research, the investigators are looking at the effects of a drug called metformin may have on the growth of abdominal aortic aneurysm (AAA)s. AAA is an abnormal enlargement of the aorta, which is the large artery in the abdomen (stomach area). The enlargement of the aorta carries a risk that it will rupture and cause life-threatening bleeding in the abdomen (belly). In this study the investigators hope to learn how metformin is associated with the enlargement or change in size of the AAA... Read More

Maintenance rTMS for Depression (Maitr-De)
Recruiting
Repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising intervention for treatment-resistant depression (TRD), yet substantial uncertainties persist regarding its efficacy as a maintenance treatment. This prospective study seeks to investigate the efficacy of maintenance rTMS in individuals with TRD who have previously responded to an acute course of rTMS. In the R61 phase of the study, we will recruit 75 participants across three study sites, the University of California... 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.
