Clinical Trials Research

Our physician investigators conduct clinical trials in communities across Southern California, from Bakersfield to San Diego.

The Division of Clinical Trials Research advances medical innovation by supporting evaluation of new drugs, therapies, and devices to prevent and treat health problems. Our physician investigators work with cooperative groups and industry sponsors to conduct clinical trials for investigational drugs, biologics, and devices. In addition, the division develops pragmatic trials that help answer questions about care delivery.

The region has clinical trials programs in oncology (adult, gynecologic, pediatric, and surgical/radiation oncology), urology, gynecology, neurology, dermatology, metabolic diseases, nephrology, ophthalmology, infectious disease, cardiology, hepatology, vascular surgery, and rheumatology. Clinical trials staff support trials at medical centers and medical office buildings throughout the Kaiser Permanente Southern California Region.
