Petros Grivas discussed Neeraj Agarwal's insights about the latest prostate cancer study results that will impact patient care as presented at ASCO GU 2019.  The ARAMIS trial evaluated the efficacy of darolutamide for delaying metastasis and death in men with nonmetastatic, castration-resistant prostate cancer.  Darolutamide is a structurally unique androgen-receptor antagonist that is under development for the treatment of prostate cancer. Neeraj discusses the interim analysis Karim Fizazi presented on the Efficacy and Safety Study of Darolutamide in Men With High-risk Nonmetastatic Castration-resistant Prostate Cancer (ARAMIS).  

In total, 1509 patients underwent randomization (955 to the darolutamide group and 554 to the placebo group). In the planned primary analysis, which was performed after 437 primary end-point events had occurred, the median metastasis-free survival was 40.4 months with darolutamide, as compared with 18.4 months with placebo (hazard ratio for metastasis or death in the darolutamide group, 0.41; 95% confidence interval, 0.34 to 0.50; P<0.001). 

Neeraj and Petros also discuss the results of the final analysis of LATITUDE and the first results as presented in metastatic hormone sensitive prostate cancer (mHSPC) patients from the ARCHES trial.  The results show that enzalutamide plus androgen deprivation therapy (ADT) met the primary endpoint by significantly reducing the risk of radiographic progression or death by 61% versus ADT alone (n=1,150; HR=0.39 [95% CI: 0.30-0.50]; p<0.0001).  The treatment of prostate cancer has continued to evolve since 2010 and the new data presented here adds to the opportunities in treating men with advanced prostate cancer.
