Excerpt:
Secondary endpoints included time to mCRPC stratified by HRR gene and time to treatment failure (TTF) in HRR altered vs WT pts, stratified by therapy. Stratified by individual HRR gene, pts with BRCA2, CDK12, or co-occurring alterations had significantly decreased time to mCRPC compared to other HRR alterations...In terms of mHSPC therapy, 45.7% were treated with ADT alone, 27.8% with an androgen receptor signaling inhibitor (ARSI), and 26.5% with docetaxel. TTF was inferior in HRR altered vs WT pts (10.8 vs 13.8 mos, p-0.004, HR- 1.84). Stratified by therapy, TTF was inferior in HRR altered vs WT pts treated with ADT alone (8.9 vs 13.3 mos, p- 0.019, HR-1.94) and there was no significant difference in TTF in HRR altered vs WT pts treated with either the addition of an ARSI or docetaxel. HRR alterations are associated with worsened outcomes in mHSPC patients.
