The purpose of this study is to evaluate the safety and effectiveness of AAA817 and an Androgen receptor pathway inhibitor (ARPI) given compared to the standard of care options.
AAA817 is experimental, which means it is being tested and is not yet approved by the United States Food and Drug Administration (FDA).
In this study, AAA817 will be given intravenously (meaning through a needle in the vein directly into the blood). The Androgen receptor pathway inhibitor (ARPI) will be given orallly.
Participants will be randomized into one of two treatment groups. Randomization is like flipping a coin and there is a 50/50 chance of being assigned to either group.
Participation is expected to last 6.1 years.
Detailed eligibility will be reviewed when contacting the study team.
