Primary Outcome Measures
NameTimeMethod
Progression Free Survival (PFS)Estimated up to 24 months

PFS based on blinded Independent Review Committee (BIRC) assessment according to International Primary Central Nervous System Lymphoma Collaborative Group (IPCG) criteria, defined as time from randomization to progressive disease (PD) or death due to any cause, whichever occurs first.

Secondary Outcome Measures
NameTimeMethod
Overall Response Rate (ORR)Estimated up to 48 months]

ORR based on BIRC per IPCG criteria, defined as the percentage of participants with a best overall response of complete response (CR), unconfirmed complete response (CRu), or partial response (PR).

Overall Survival (OS)Estimated up to 48 months

OS defined as time from randomization until death due to any cause.

Complete Response Rate (CRR)Estimated up to 48 months

CRR based on BIRC per IPCG criteria, defined as the percentage of participants with a best overall response of CR or CRu.

Best Overall Response (BOR)Estimated up to 48 months]

BOR based on BIRC per IPCG criteria, defined as the best response from randomization to the date of PD or the date of initiation of subsequent anticancer therapy for PCNSL, whichever occurs first.

Time to Response (TTR)Estimated up to 48 months

TTR based on BIRC per IPCG criteria, defined as time between randomization and the date of first response of CR, CRu, or PR.

Time to Complete Response (TTCR)Estimated up to 48 months

TTCR based on BIRC per IPCG criteria, defined as the time between randomization and the date of first complete response (CR or CRu).

Duration of Response (DOR)Estimated up to 48 months

DOR based on BIRC per IPCG criteria, defined as the time between the date of first response (CR, CRu, or PR) and the date of the first PD or date of death due to any cause, whichever occurs first.

Disease Free Survival (DFS)Estimated up to 48 months

DFS based on BIRC per IPCG criteria, defined as the time between the date of first complete response (CR or CRu) and the date of the first PD, or date of death due to any cause, whichever occurs first.
