Comparing the New Anti-cancer Drug Eribulin With Chemotherapy Against the Usual Chemotherapy Alone in Metastatic Urothelial Cancer
Recruiting
This phase III trial compares the usual chemotherapy treatment to eribulin plus gemcitabine in treating patients with urothelial cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Chemotherapy drugs, such as eribulin, gemcitabine, docetaxel, paclitaxel, and sacituzumab govitecan work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This tri... Read More

Testing the Use of Steroids and Tyrosine Kinase Inhibitors With Blinatumomab or Chemotherapy for Newly Diagnosed BCR-ABL-Positive Acute Lymphoblastic Leukemia in Adults
Recruiting
This phase III trial compares the effect of usual treatment of chemotherapy and steroids and a tyrosine kinase inhibitor (TKI) to the same treatment plus blinatumomab. Blinatumomab is a Bi-specific T-Cell Engager ('BiTE') that may interfere with the ability of cancer cells to grow and spread. The information gained from this study may help researchers determine if combination therapy with steroids, TKIs, and blinatumomab work better than the standard of care.

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.
