Dr. Beer has authored and co-authored more than 350 articles and abstracts on prostate cancer largely with a focus on the development of novel therapies through clinical and translational investigation. He co-authored the book Cancer Clinical Trials: A Commonsense Guide to Experimental Cancer Therapies and Clinical Trials. Dr. Beer is particularly known for investigations of targeted therapies and immunotherapies in prostate cancer, including vitamin D receptor, the androgen receptor, and clusterin targeting agents as well as cancer vaccines, CTLA-4 and PD-1 inhibitors, and others. He led the global randomized trial of enzalutamide vs placebo which demonstrated substantial improvements in overall and progression-free survival as well as quality of life and served as the basis for a global change in the standard of care for advanced prostate cancer. Dr. Beer cares for men with prostate cancer at OHSU and at the Portland VA Medical Center.
