Arm Intervention/treatment
Experimental: Tirabrutinib monotherapy in patients with relapsed or refractory PCNSL (Part A)
Patients with relapsed or refractory PCNSL who meet eligibility criteria will be enrolled to receive tirabrutinib monotherapy.
Drug: Tirabrutinib
Part A: Tirabrutinib 480 mg, taken orally, once a day on an empty stomach. Tirabrutinib treatment may be continued until disease progression or clinically unacceptable toxicity is observed.
Other Name: ONO-4059

Experimental: Tirabrutinib + MTR in patients with newly diagnosed, treatment naïve PCNSL (Part B, Arm 1)
Patients with newly diagnosed treatment naïve PCNSL who meet eligibility criteria will be enrolled to receive tirabrutinib + methotrexate/temozolomide/rituximab (MTR)
Drug: Tirabrutinib

Part B, Arm 1 - Tirabrutinib 320 mg or 480 mg, taken orally, once a day on an empty stomach in combination with an MTR induction regimen. Tirabrutinib with MTR treatment will be continued for 4 induction cycles (28-day/cycle), or until disease progression or clinically unacceptable toxicity is observed.

For patients not receiving consolidation treatment following induction, tirabrutinib 480 mg will be continued until disease progression, unacceptable toxicities are observed, or the Investigator decides to stop treatment.

Tirabrutinib with R-MPV treatment will be continued for 4 induction cycles (28-day/cycle), or until disease progression or clinically unacceptable toxicity is observed.

For patients not receiving consolidation treatment following induction, tirabrutinib 480 mg will be continued until disease progression, unacceptable toxicities are observed, or the Investigator decides to stop treatment.

Other Name: ONO-4059




Primary Outcome Measures :
  1. Overall response rate (ORR) (Part A) [ Time Frame: 1 year ]
    Overall response rate is defined as the proportion of patients with a best overall response of Complete response (CR), Complete response - unconfirmed (CRu), or (=partial response (PR) as determined by an independent review committee according to the International PCNSL Collaborative Group (IPCG) criteria.

  2. Tirabrutinib dose estimate (Part B) [ Time Frame: 1 month ]
    Estimate of tirabrutinib dose in combination with each backbone induction regimen (MTR and R-MPV) based upon treatment related AEs, SAEs, and toxicities observed during the initial cycle of induction therapy in the dose-ranging phase

  3. Incidence and severity of adverse events (AEs) and serious adverse events (SAEs) during induction (Part B) [ Time Frame: 4 months ]
    Adverse events at each visit with the NCI CTCAE v5.0 used as a guide for the grading of severity.

  4. Complete response rate (CRR) (Part B) [ 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.


Secondary Outcome Measures :
  1. Duration of response (DOR) (Part A and B) [ Time Frame: 2 years ]
    Duration of response is defined as the time between the date of first response (CR, CRu, or PR) and the date of the first PD according to the IPCG criteria, or date of death due to any cause, whichever occurs first.

  2. Time to response (TTR) (Part A and B) [ 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.

  3. Best overall response (BOR) (Part A and B) [ 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.

  4. Change in corticosteroid dose (Part A) [ Time Frame: 2 years ]
    Descriptive statistics will be calculated for the actual corticosteroid dose and the change from baseline at each assessment point.

  5. Incidence and severity of AEs and SAEs (Part A and B) [ Time Frame: 2 years ]
    Adverse events at each visit with the NCI CTCAE v5.0 used as a guide for the grading of severity.

  6. Laboratory abnormality profile of tirabrutinib as measured by incidence and severity of clinical laboratory abnormalities (Part A and B) [ Time Frame: 2 years ]
    Results of laboratory tests

  7. ECG parameters by 12 lead ECG (Part A and B) [ Time Frame: 2 years ]
    Heart rate, RR and QT intervals, QTc (QTcF, QTcB), PR interval, and QRS width.

  8. PK parameters (Cmax) of tirabrutinib in the plasma (Part A and B) [ Time Frame: 29 days ]
  9. PK parameters (Tmax) of tirabrutinib in the plasma (Part A and B) [ Time Frame: 29 days ]
  10. PK parameters (AUC) of tirabrutinib in the plasma (Part A and B) [ Time Frame: 29 days ]
