Apalutamide + Hormone and Radiation Therapies

for Prostate Cancer

This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.
