Principal Investigator: Alfredo Daniel Voloschin, MD
Phase: Drug: Phase II
Age Group: Adult
Secondary Protocol No: ONO-4059-09
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. Other Name: ONO-4059 Experimental: Tirabrutinib + R-MPV in patients with newly diagnosed, treatment naïve PCNSL (Part B, Arm 2) 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 Part B, Arm 2 - Tirabrutinib 320 mg or 480 mg, taken orally, once a day on an empty stomach in combination with an R-MPV induction regimen. 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.
