NCT04947319

Brief Summary

This study will evaluate the efficacy, safety, and pharmacokinetics of tirabrutinib monotherapy in patients with relapsed or refractory PCNSL (Part A), and tirabrutinib in combination with one of two different high dose methotrexate based regimens (methotrexate/ temozolomide/rituximab or rituximab/methotrexate/procarbazine/ vincristine) as first line therapy in patients with newly diagnosed, treatment naïve PCNSL (Part B)

Outcome Measures

Primary Outcomes (4)

  • Overall response rate (ORR) (Part A)

    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.

    1 year

  • Tirabrutinib dose estimate (Part B)

    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

    1 month

  • Incidence and severity of adverse events (AEs) and serious adverse events (SAEs) during induction (Part B)

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

    4 months

  • Complete response rate (CRR) (Part B)

    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

Secondary Outcomes (10)

  • Duration of response (DOR) (Part A and B)

    2 years

  • Time to response (TTR) (Part A and B)

    1 year

  • Best overall response (BOR) (Part A and B)

    1 year

  • Change in corticosteroid dose (Part A)

    2 years

  • Incidence and severity of AEs and SAEs (Part A and B)

    2 years

  • +5 more secondary outcomes

Study Arms (3)

Tirabrutinib monotherapy in patients with relapsed or refractory PCNSL (Part A)

EXPERIMENTAL

Patients with relapsed or refractory PCNSL who meet eligibility criteria will be enrolled to receive tirabrutinib monotherapy.

Drug: Tirabrutinib

Tirabrutinib + MTR in patients with newly diagnosed, treatment naïve PCNSL (Part B, Arm 1)

EXPERIMENTAL

Patients with newly diagnosed treatment naïve PCNSL who meet eligibility criteria will be enrolled to receive tirabrutinib + methotrexate/temozolomide/rituximab (MTR)

Drug: Tirabrutinib

Tirabrutinib + R-MPV in patients with newly diagnosed, treatment naïve PCNSL (Part B, Arm 2)

EXPERIMENTAL

Patients with newly diagnosed treatment naïve PCNSL who meet eligibility criteria will be enrolled to receive tirabrutinib + rituximab/methotrexate/procarbazine/vincristine (R-MPV)

Drug: Tirabrutinib

Interventions

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.
