Biography

Dr. Samuel Denmeade is a professor of oncology and urology at the Johns Hopkins School of Medicine. He also has appointments in the Department of Pharmacology and Molecular Sciences and Department of Biomolecular Engineering. His areas of clinical expertise include bladder cancer, kidney cancer, prostate cancer and testicular cancer.

Dr. Denmeade earned his M.D. from the Columbia College of Physicians and Surgeons of Columbia University. He completed his residency at the University of Chicago. He performed a fellowship in oncology at The Johns Hopkins Hospital and a fellowship in medical oncology at the Johns Hopkins University School of Medicine.

His research interests include prostate and renal cancer, bladder cancer and targeted drug development.

Dr. Denmeade was named the Carolyn and Bill Stutt Scholar by The Patrick C. Walsh Prostate Cancer Research Fund in 2012.

    Research Summary

    The main research goals of Dr. Denmeade’s laboratory are: (1) to identify and study the biology of novel cancer selective targets whose enzymatic function can be exploited for therapeutic and diagnostic purposes; (2) to develop methods to target novel agents for activation by these cancer selective targets while avoiding or minimizing systemic toxicity; and (3) to develop new hormonal therapies for prostate cancer based on underlying biology.

    To accomplish these objectives the lab has originally focused on the development of prodrugs or protoxins that are inactive when given systemically via the blood and only become activated by tumor or tissue specific proteases present within sites of tumor.

    Using this approach, Dr. Denmeade and his lab are developing therapies targeted for activation by the serine proteases prostate-specific antigen (PSA), human glandular kallikrein 2 (hK2) and fibroblast activation protein (FAP) as well as the membrane carboxypeptidase prostate-specific membrane antigen (PSMA). One such approach developed in the lab consists of a potent bacterial protoxin that they have reengineered to be selectively activated by PSA within the Prostate. This PSA-activated toxin is currently being tested clinically as treatment for men with recurrent prostate cancer following radiation therapy. In a related approach, a novel peptide-cytotoxin prodrug candidate that is activated by PSMA has been identified and is this prodrug candidate is now entering early phase clinical development. In addition, they have also identified a series of potent inhibitors of PSA that are now under study as drug targeting and imaging agents to be used in the treatment and detection of prostate cancer.
