Prostate cancer study pulled before it began

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Participants with lymph node-only disease are not eligible. * Willing to provide tumor tissue (archival) for determination of deleterious germline or somatic HRR gene alterations, if no local (testing done at investigator center or commercial testing) or prior sponsor-approved test result is available. 1.Testing must demonstrate pathogenic gene alterations in ≥1 of the following genes to proceed to screening: ATM, BRCA1, BRCA2, BRIP1, CDK12, CHEK2, FANCA, HDAC2, or PALB2. * Castration-resistant disease, defined by the PCWG3 as any of the following criteria while on castrate levels of testosterone (less than or equal to 50 ng/dL): 1.
