What is Clinical Research?

The physicians and research staff at TOA have many years of experience performing research from advanced devices for spine surgery to the latest biotech pharmaceuticals. We are assisting local universities as well as national networks of researchers in learning more about the causes of the different forms of arthritis. We have participated in clinical trials of most of the rheumatoid arthritis medications that have become available over the past 20 years including Enbrel, Humira, Orencia, Rituxan, Kineret, Actemra, and Cimzia as well as the major anti-inflammatory medications. In addition to rheumatoid arthritis, our studies have included research on gout, pain, osteoarthritis, and various types of back and neck arthritis and disc disease. In our opinion, the availability of clinical research is a major resource for our patients allowing them access to cutting edge therapies when established medications and procedures are not satisfactory. Our participation also keeps us at the forefront of the newest advances. Please check our site often or contact us if you are interested in possible participation in a clinical trial. We are frequently starting new research projects. Please contact us at AllClinicalResearch@triangleortho.com
