Study Endpoints
Primary Endpoints
Biochemical response rate (Phase II)
from date of randomization up to approximately 24 months

Biochemical response rate as defined as the percentage of participants who achieved a ≥ 50% decrease from baseline that is confirmed by a second measurement

Adverse Events (AEs) and Serious Adverse Events (SAEs), and deaths - Phase II
from day of randomization to 30 days after End of Treatment or (last AAA817 dose date + 55 days, last dose date of SoC + 30 days), whichever is later

Safety defined as the type, incidence and severity of AEs and SAEs, and deaths

Tolerability of the proposed dose of AAA817- Phase II
From on-treatment period which start from the first dose of study treatment until 30 days post-last dose date for SoC and 55 days post last-dose for AAA817

Percentage of participants who experienced Dose interruptions, reductions, discontinuation, dose intensity and duration of exposure

Radiographic progression-free survival (rPFS)- Phase III
from date of randomization up to approximately 24 months

Percentage of participants who are alive without radiographic progression or who are lost to follow-up at the time of analysis

Overall survival (OS)- Phase III
from date of randomization up to approximately 24 months

Percentage of participants who are alive or who are lost to follow-up at the time of analysis

Secondary Endpoints
Radiographic progression-free survival (rPFS)- Phase II
from date of randomization up to approximately 24 months
Progression free survival (PFS)- Phase II
from date of randomization up to approximately 24 months
