Methotrexate | Methotrexate sodium | CNS prophylaxis protocol |
Cytarabine | Cytosar-U | CNS prophylaxis protocol |
This is a prospective phase 2 clinical trial of systemic central nervous system prophylaxis among patients with diffuse large B-cell lymphoma at high risk of central nervous system recurrence. The main objective is to evaluate safety and efficacy of early institution of intensive central nervous system prophylaxis in a high-risk group to minimize the risk of a devastating central nervous system recurrence. Patients receive standard primary immunochemotherapy with an addition of planned central nervous system prophylaxis courses on or around day 15 of cycles 2, 4, and 6. Growth factor support and Pneumocystis jirovecii prophylaxis is required. The primary endpoint of this pilot study is protocol-defined toxicity, whereas efficacy (cumulative incidence of central nervous system recurrence) will be a secondary endpoint.
