Overview
The purpose of this clinical trial is to evaluate efficacy and safety of tirabrutinib alone compared with rituximab and temozolomide (R-TMZ) combination therapy in participants with Relapsed/Refractory Primary Central Nervous System Lymphoma (PCNSL).
Interventions
- Drug Tirabrutinib
Administered orally. - Drug Rituximab
Administered intravenously (IV). - Drug Temozolomide
Administered orally.
Primary outcome measures
- Progression Free Survival (PFS) [Time frame: Estimated up to 24 months]
Secondary outcome measures (9)
- Overall Response Rate (ORR) [Time frame: Estimated up to 48 months]]
- Overall Survival (OS) [Time frame: Estimated up to 48 months]
- Complete Response Rate (CRR) [Time frame: Estimated up to 48 months]
- Best Overall Response (BOR) [Time frame: Estimated up to 48 months]]
- Time to Response (TTR) [Time frame: Estimated up to 48 months]
- Time to Complete Response (TTCR) [Time frame: Estimated up to 48 months]
- Duration of Response (DOR) [Time frame: Estimated up to 48 months]
- Disease Free Survival (DFS) [Time frame: Estimated up to 48 months]
- Change from Baseline in Corticosteroid Dose [Time frame: Baseline, estimated up to 48 months]
Eligibility criteria
Inclusion criteria
- Pathology report confirming the diagnosis of B-cell PCNSL
- Relapsed or refractory B-cell PCNSL with at least 1 prior high-dose methotrexate (HD-MTX) based therapy for PCNSL:
- Relapsed disease: Participants who achieved a response (CR, CRu, PR) to the last treatment and subsequently experienced disease progression.
- Refractory disease: Participants whose best response to the last treatment was stable disease or PD.
- One or more bi-dimensionally measurable brain lesions with a minimum diameter greater than or equal to (≥)1 centimeter (cm) × ≥1 cm in gadolinium-enhanced magnetic resonance imaging (MRI)

Exclusion criteria
- Participants with isolated intraocular PCNSL or spinal PCNSL with no brain lesions
- Participants with non-B-cell PCNSL
- Participants with systemic presence of lymphoma
- Refractory to temozolomide with or without rituximab-containing regimens in the last PCNSL treatment
- Concomitant systemic corticosteroid exposure within 14 days before starting study drug per Investigator assessment with the exception of the following:
- Equivalent of up to 10 milligram per day (mg/day) of prednisone for a disease other than PCNSL
- Equivalent of up to 50 mg/day of prednisone (equal to 8 mg/day dexamethasone) for participants with lesions of the brain and/or spinal cord
- Active malignancy, other than PCNSL requiring systemic therapy
- Poorly controlled comorbidity, or history of medical conditions contraindicated per Investigator assessment
