Idiopathic Hypersomnia (IH) is a condition where people feel extremely sleepy during the day, especially in the morning, even if they sleep a lot at night. They may have trouble waking up in the morning, no matter how much they sleep (sometimes more than 11 hours per day), and they can't help feeling tired, even after taking daytime naps. Because of this sleepiness, they may have trouble focusing, thinking clearly, or keeping up with daily activities. They may also have symptoms like dizziness o... Read More

Non-healing Venous Leg Ulcers Treated With Standard Care With or Without BR-AC
Recruiting
This study examines a patient population with a non-healing, non-infected venous leg ulcer (VLU) having adequate arterial perfusion with confirmed venous reflux. It is hypothesized that weekly applications of the human placental allograft BioREtain® Amnion Chorion (BR-AC) applied to a non-healing VLU will result in a higher proportion of wounds showing complete healing within 12 weeks of initiating therapy, compared to standard care alone.
This study has a crossover period, where subjects on st... Read More

Comparing New Treatments for People With Newly Diagnosed Acute Myeloid Leukemia That Has an IDH2 Gene Change (A MyeloMATCH Treatment Trial)
Recruiting
This phase II MyeloMATCH treatment trial studies how well ASTX727 and venetoclax plus enasidenib works compared to ASTX727 and venetoclax alone for the treatment of older patients with newly diagnosed acute myeloid leukemia (AML) or younger patients who are considered unfit for standard treatment, and who have an abnormal change (mutation) in the IDH2 gene. This gene mutation can cause AML to grow and spread. This trial is being done to see if adding enasidenib to the usual treatment can help mo... Read More

Testing the Addition of an IDH2 Inhibitor, Enasidenib, to Usual Treatment (Cedazuridine-Decitabine) for Higher-Risk Myelodysplastic Syndrome (MDS) With IDH2 Mutation (A MyeloMATCH Treatment Trial)
Recruiting
This phase II MyeloMATCH treatment trial compares the usual treatment of cedazuridine-decitabine (ASTX727) to the combination treatment of ASTX727 and enasidenib in treating patients with higher-risk, IDH2-mutated myelodysplastic syndrome (MDS). ASTX727 is a combination of two drugs, decitabine and cedazuridine. Cedazuridine is in a class of medications called cytidine deaminase inhibitors. It prevents the breakdown of decitabine, making it more available in the body so that decitabine will have... 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.
