OKLAHOMA CITY, OKLA. – With a $1.2 million grant to the University of Oklahoma, an OU Health urologic oncologist is leading an innovative new clinical trial for the treatment of prostate cancer when the cancer is beginning to spread beyond the prostate. The trial, offered at OU Health Stephenson Cancer Center, will study the combination of two drugs, each of which is already used to treat prostate cancer but has not been evaluated together.
