HOUSTON – Clinical trials show that an immune checkpoint inhibitor shrinks the tumors of nearly half of patients with an incurable, advanced form of a common skin cancer, an international team led by a researcher at The University of Texas MD Anderson Cancer Center reports in the New England Journal of Medicine.
