Survey Based Discrete Choice Experiment Study in Prostate Cancer (DECIDER) Study
January 10, 2023 updated by: Astellas Pharma Global Development, Inc.
Prospective Evaluation of Patient Preferences for Outcomes of Hormonal Agents and Chemotherapy in Combination With Androgen Deprivation Therapy
The purpose of this study is to quantify and publish participants' relative preferences for outcomes of chemotherapy and novel oral hormonal agents when added to androgen deprivation therapy (ADT) for participants with locally-advanced and metastatic hormone-sensitive prostate cancer (mHSPC).
This study will also quantify the importance of administration factors related to convenience relative to treatment outcomes.
