Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Tolerability evaluation
Time Frame: 29 Days

The number of subjects who experienced adverse events and side effects will be tallied. In the tolerability evaluation part, the number of subjects who experienced Dose Limiting Toxicity(DLT) will be tallied

29 Days
Incidence and severity of adverse events (AEs) and serious adverse events (SAEs) during induction
Time Frame: 2 years

Adverse events at each visit with the NCI CTCAE v5.0 used as a guide for the grading of severity.

2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Summary of plasma tirabrutinib concentration at trough and post 2 hours dosing
Time Frame: 30days
30days
Duration of response (DOR)
Time Frame: 2 years

Duration of response is defined as the time between the date of first response (Complete response (CR), Complete response - unconfirmed (CRu), or partial response (PR) ) and the date of the first progressive disease(PD) according to the IPCG criteria, or date of death due to any cause, whichever occurs first.

2 years
Time to response (TTR)
Time Frame: 1 year

Time to response is defined as the time between the date of first administration of tirabrutinib and the date of first response (CR, CRu, or PR) as determined by IRC according to the IPCG criteria.

1 year
Best overall response (BOR)
Time Frame: 1 year

Best overall response based on independent review committee (IRC) response determination is defined as the best response and is derived programmatically based upon the visit responses determined by IRC from the date of administration of tirabrutinib to the date of PD as determined by IRC or the date of initiation of subsequent anticancer therapy for PCNSL, whichever occurs first.

1 year
Complete response rate (CRR)
Time Frame: 4 months

Complete response rate is defined as the proportion of patients with a best overall response of CR or CRu as determined by an independent review committee according to the IPCG criteria.

4 months
