Abstract 1810P
Background
This post hoc analysis of the phase 3 VISION study of [177Lu]Lu-PSMA-617 (177Lu-PSMA-617) plus standard of care (SoC) vs SoC alone in adults with progressive, prostate-specific membrane antigen (PSMA)-positive metastatic castration-resistant prostate cancer (mCRPC), assessed associations of PSA decline, radiographic progression-free survival (rPFS) and overall survival (OS) with time to worsening (TTW) of health-related quality of life (HRQoL).
Methods
Associations of PSA decline with TTW of HRQoL (n = 385) were assessed in the 177Lu-PSMA-617 arm. Patients were grouped by PSA decline (unconfirmed) overall or up to 12 weeks of treatment: no decline, ≤ 50%, > 50 to ≤ 90% and > 90%. Worsening of HRQoL was defined as a decrease of ≥ 10 (total) or ≥ 3 (subdomain) points in FACT-P, an increase of ≥ 2 points in BPI-SF or any decrease in EQ-5D-5L. Associations of rPFS or OS with TTW of HRQoL were carried out in the full analysis set (FAS; N = 831) using three Spearman’s rank methods (restricted, highest rank, iterative multiple imputation), with and without imputation for missing OS and rPFS data.
Results
In the 177Lu-PSMA-617 arm, greater PSA decline overall and up to 12 weeks of treatment was associated with longer median TTW in FACT-P total and subdomain scores (Table). Correlations of rPFS and OS with and without imputation with TTW of HRQoL were positive and significantly different to zero in both arms, but mainly weak/moderate. In the total FAS without imputation, rPFS correlations were 0.27–0.51 (FACT-P total), 0.19–0.34 (EQ-5D-5L) and 0.26–0.47 (BPI-SF severity); OS correlations were 0.41–0.55 (FACT-P total), 0.13–0.31 (EQ-5D-5L) and 0.20–0.55 (BPI-SF severity).

Conclusions
Greater PSA decline and increased rPFS and OS were associated with longer TTW of HRQoL. Ongoing analyses will assess associations of other HRQoL measures with PSA decline and overall response rate.
