GENITOURINARY CANCERS

A significant proportion of patients with metastatic castration-resistant prostate cancer with DNA repair gene aberrations responded well to treatment with olaparib in a phase II TOPARP-B trial, making olaparib the first targeted therapy to show benefit in this patient population, the Institute of Cancer Research reported in a press release.

In patients whose solid<strong> </strong>tumors harbor a mutation in <em>KRAS </em>G12C, therapy with MRTX849 has produced promising responses and acceptable toxicity across 3 tumors types, according to data presented at the 2019 American Association for Cancer Research&ndash;National Cancer Institute&ndash;European Organization for Research and Treatment of Cancer International Conference on Molecular Targets and Cancer Therapeutics.

The combination of onvansertib with abiraterone acetate decreased the prostate-specific antigen levels in most of the evaluable patients treated in a phase II study, which used the combination in adult patients with metastatic castration-resistance prostate cancer, according to a press release from onvansertib developer, Trovagene, Inc.

Male patients with advanced prostate cancer had a 97% response rate to relugolix, a gonadotropin-releasing hormone receptor antagonist, in the phase III HERO study, meeting the primary end point of the study. The trial also met all 6 of its key secondary end points, according to a press release from Myovant Sciences.

The early development of PARP inhibitors in 2003 focused on their use in combination with cytotoxic chemotherapy agents, but this was eventually abandoned because of excess toxicity.

In an interview with&nbsp;Targeted Oncology during the 2019 Prostate Cancer Consensus Conference, James L. Mohler, MD, explained the reasons for changes to the NCCN guidelines on genetic testing and counseling in prostate cancer. He also discussed what needs to be addressed in the future to further increase knowledge of genetic testing and improve its use.

William K. Oh, MD, discusses the rationale for presenting the data for the phase III ENZAMET trial in a plenary session at the 2019 ASCO Annual Meeting. He says these data were significant because it was a large randomized clinical trial for the treatment of newly diagnosed patients with metastatic hormone-sensitive prostate cancer.

Apalutamide plus androgen deprivation therapy maintained health-related quality of life in patients with metastatic castration-sensitive prostate cancer in addition to showing positive overall survival and radiographic progression-free survival outcomes in the phase III TITAN trial, said Neeraj Agarwal, MD.

A. Oliver Sartor, MD, discusses a discrepancy found between conventional imaging and PSMA PET/CT scanning for prostate cancer.&nbsp;

In an interview with&nbsp;Targeted Oncology, Alan Bryce, MD, discussed the significance of the data from PROfound for men with mCRPC. He also highlighted findings from the CARD trial and where the field is headed in terms of targeted therapies versus chemotherapies.
