This study aims to document tx patterns and outcomes of pts with mCRPC who received tx in a prior setting. METHODS: A non-interventional, retrospective cohort study of pts with mCRPC in the United States was conducted using data from Flatiron Health's electronic health record database. Pts were included if they were diagnosed with mCRPC between January 1, 2016 and July 31, 2023 and received 1L tx for mCRPC as defined by Flatiron. Results were described for the total cohort and by the txs received prior to mCRPC: 1) NHT exposed only, 2) taxane exposed only, 3) NHT and taxane exposed, 4) NHT and taxane naïve. RESULTS: 4,615 pts received 1L mCRPC tx and all had received tx prior to mCRPC diagnosis; median age: 74 years; White race: 60.6%, Black race 11.2%; Gleason score ≥7: 77.4%, unknown: 16.2%. Overall, most patients were NHT and taxane naïve (n=3,425, 74.2%), 708 (15.3%) were NHT exposed only, 411 (8.9%) were taxane exposed only, and 71 (1.5%) were NHT and taxane exposed. Prior tx use differed by year and unadjusted median overall survival (mOS) from mCRPC 1L tx differed by prior tx(s) received; results are reported in the Table 1. CONCLUSIONS: The use of systemic txs in settings prior to mCRPC is increasing over time, however, majority of pts remain NHT and/or taxane naïve at mCRPC diagnosis. Unadjusted mOS from mCRPC 1L tx differed by prior tx received suggesting tx sequence may impact outcomes.
