Trial Outcomes & Findings for A Study to Learn About Novel Hormonal Therapies in People With Metastatic Castration-Sensitive Prostate Cancer (mCSPC) (NCT NCT06072196)

NCT ID: NCT06072196

Last Updated: 2025-12-31

Results Overview

Treatment duration was defined as the time from the initial claim date of NHT (abiraterone, apalutamide, or enzalutamide) until the end of observation for any of the following reasons: (i) end of data availability (December 31, 2022), (ii) participant's date of death, (iii) day before a treatment switch, (iv) day of treatment discontinuation (a 90-day gap in days supply was considered as discontinuation). Retrospective retrieved data collected was evaluated for approximately 1.2 years of this study. Kaplan-Meier method was used for estimation.

Participant Flow

Data for eligible participants with metastatic castration-sensitive prostate cancer (mCSPC), who initiated a novel hormonal therapy (NHT) \[abiraterone or apalutamide or enzalutamide\] and had its claim from 01-Jan-2020 to 31-Dec-2021 (index window) were retrieved from existing administrative data from Original Medicare.

Retrospective data were retrieved and evaluated per objectives of this observational study from 04-Oct-2023 to 18-Dec-2024 (approximately 1.2 years).
