Abstract:

Background: AQUARiUS is an ongoing study of PROs and medical resource use in chemotherapy-naïve pts with mCRPC newly initiated on AAP or ENZ in a real-world setting. Initial 3-month (mo) subset analyses suggested favorable outcomes for AAP vs ENZ in cognition and fatigue. We report 6-mo results. Methods: AQUARiUS prospectively collects PROs on quality of life, cognition, fatigue, and pain using EORTC QLQ-C30, FACT-Cog, BFI-SF, and BPI-SF questionnaires, over 12 mos. PROs were collected at baseline (BL) and during visits based on real-world practice schedules. Incidence of clinically meaningful worsening (CMW) and change from BL scores were determined, adjusting for BL characteristics. Results: All 211 pts were analyzed (AAP, n = 105; ENZ, n = 106). BL characteristics were well balanced (no significant differences). A significantly lower proportion of pts on AAP vs ENZ experienced CMW for cognition and fatigue during the first 6 mos of treatment (TABLE). Clinical trial information: NCT02813408 PRO scales with consistent significant differences (p< 0.05 for ≥ 3 consecutive time points) in change from BL scores were “perceived cognitive impairments” and “comments from others” (FACT-Cog); “fatigue right now,”“usual level of fatigue,” and “worst level of fatigue” (BFI-SF); and “cognitive functioning” and “fatigue” (EORTC QLQ-C30); all favored AAP over ENZ. Where significant differences for these scales were not maintained through the full 6-mo period, nonsignificant trends in favor of AAP were observed. Conclusions: These 6-mo results continue to suggest that AAP provides favorable outcomes vs ENZ for certain measures of cognition and fatigue in pts with mCRPC.
