Active Clinical Trials at CHI Health

A clinical trial (also clinical research) is a research study in human volunteers to answer specific health questions. Carefully conducted clinical trials are the fastest and safest way to find treatments that are effective in human subjects. Interventional trials determine whether experimental treatments or new ways of using known therapies are safe and effective under controlled environments. Observational trials address health issues in large groups of people or populations in natural settings.

Clinical trials are ongoing and some may not be listed. If you have any questions please call the CHI Health Research office at (402) 343-8511.
