Study Endpoints
Primary Endpoints
Progression Free Survival (PFS) assessed by Blinded Independent Central Review (BICR) per modified Response Assessment in Neuro-Oncology (RANO) 2.0
From the date of randomization until the date of first documented disease progression, approximately 30 months

PFS, defined as time from date of randomization to the date of the first occurrence of radiographic disease progression per modified RANO 2.0 assessed by BICR or death from any cause, whichever occurs earlier

Part 1: Incidence of adverse events (AEs) and serious adverse events (SAEs)
From participants sign ICF to 30 days after last dose,average 2 years

calculate Percentage and numbers of participants with treatment emergent adverse events (TEAEs) and serious adverse events (SAEs) assessed by CTCAE 5.0

Part 2: Progression-free survival (PFS) assessed by Blinded Independent Central Review (BICR) per Response Assessment in Neuro-Oncology (RANO) 2.0
From randomization until the date of first documented disease progression, average 2 years

PFS is defined as the time from randomization to the date of the first documented disease progression assessed by BICR per RANO 2.0 or death (by any cause in the absence of disease progression).

Part 3 Objective Response Rate (ORR) (Complete Response (CR), Partial Response (PR) and Minor Response (MR)) assessed by Blinded Independent Central Review (BICR) per Response Assessment in Neuro-Oncology (RANO) 2.0
From the first dose of study drug until the date of first documented disease progression, average 18 months
Objective Response Rate (ORR) per modified Response Assessment in Neuro-Oncology (RANO) 2.0 assessed by Blinded Independent Central Review (BICR)
From the date of first dose of study drug until the date of first documented disease progression, approximately 18 months

ORR defined as the proportion of participants with the confirmed best overall response of Complete Response (CR), Partial Response (PR) or Minor Response (MR) per modified RANO 2.0, assessed by BICR

Secondary Endpoints
Objective Response Rate (ORR) assessed by BICR per modified RANO 2.0
From the date of randomization until the date of first documented disease progression, approximately 30 months
Time to Next Intervention (TTNI)
From the date of randomization until the date of the start of another anticancer treatment or date of death, approximately 30 months
PFS assessed by the Investigator per modified RANO 2.0
From the date of randomization until the date of first documented disease progression, approximately 30 months
