Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
JSB462 administration starts at day 1 of randomization, whereas AAA617 administration starts at day 1 of treatment period. Participants in arm 1 and arm 2 will therefore receive JSB462 during the 14-day randomization period before first administration of AAA617.
* JSB462 is administered orally, daily and continuously (100 mg or 300 mg once a day (QD)) until disease progression per Prostate Cancer Working Group (PCWG) 3-modified Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 as assessed by the investigator, the occurrence of unacceptable toxicities, death, participant decision or investigator decision.
* AAA617 will be administered at 7.4 gigabecquerel (GBq) intravenously every 6 weeks for up to 6 doses, unless there is disease progression per PCWG3-modified RECIST v1.1 as assessed by the investigator, the occurrence of unacceptable toxicities, death, participant decision or investigator decision.
During the post-treatment follow up period:
* Safety follow-Up: After discontinuation of study treatment, all participants will be followed for at least 1 safety follow-up visit (30 days \[+/- 7 days\] after end of treatment visit). Subsequent lines of therapy may be administered according to investigator's discretion after treatment discontinuation.
* Long-term follow-up: Starts after the Safety follow-up period and lasts until the end of study. Safety, efficacy and survival information may be collected from the participants during this period.
