Clinical Outcomes and Clinical Trials Program (COCTP)

The Clinical Outcomes and Clinical Trials Program (COCTP) centers on clinical epidemiology and outcomes research and clinical trials in the fields of nephrology and transplantation medicine. The goal of COCTP is to provide an intellectual home for nephrology clinical research while proving support and training to establish a sound research hypothesis and study design, as well as coordinating budget/contract negotiation, regulatory submission, human subject recruitment, and data management.

The Harold Simmons Center for Chronic Disease Research and Epidemiology at University of California, Irvine

The Harold Simmons Center for Chronic Disease Research and Epidemiology is located on the campus of the University of California, Irvine (UCI), California. The Center is funded by a philanthropic grant from Mr. Harold Simmons in addition to funding from NIH and various other sources. Kamyar Kalantar-Zadeh, M.D. Ph.D who is Professor of Medicine at UCI, heads the Center. Besides its main mission of chronic disease research, the Center provides research training for masters and doctoral students from the UCI/UCLA School of Public Health, students and recent college graduates interested in pursuing careers in medicine and/or medical research, and young physician investigators from all over the world. The Harold Simmons Center has expanded during these past eight years in terms of facility space as well as staff. Our clinical studies staff has expanded to include one full-time study coordinator as well as three part-time staff members and several volunteers who are seeking experience in clinical trial research while pursuing careers in medicine or the healthcare field. The Center is currently mentoring five research physicians who come from all over the world to expand their knowledge of epidemiological research methodologies. Researchers who have completed their tenure are continuing their collaboration with the Center from their respective countries using remote access technologies.
