Researchers “turbocharge” immune cells to attack prostate cancer

Pfizer announced positive topline results from the phase III TALAPRO-3 study of Talzenna (talazoparib), an oral poly ADP-ribose polymerase inhibitor, in combination with Xtandi (enzalutamide), an androgen receptor pathway inhibitor, in people with homologous recombination repair gene-mutated metastatic castration-sensitive prostate cancer, also known as metastatic hormone-sensitive prostate cancer.

Androgen receptor alterations consistently emerged in serial liquid biopsies researchers used to track how metastatic prostate cancer evolves under treatment pressure. These alterations were linked to poorer outcomes across therapies, according to a multi-center collaboration of investigators from Sylvester, UC San Diego, Moores Cancer Center, the University of California, San Francisco, Scripps Research Institute, and Guardant Health. 

A national clinical trial led by the Alliance for Clinical Trials in Oncology has found that oxybutynin, a drug often used to treat overactive bladder symptoms, reduces hot flashes compared to the placebo in men receiving hormone therapy for prostate cancer.
