Age-adjusted high-dose chemotherapy followed by autologous stem cell transplantation or conventional chemotherapy with R-MP as first-line treatment in elderly primary CNS lymphoma patients – a randomized phase III trial - PRIMA-CNS
EU CTIS ID: 2024-512320-11-00
What this study is testing
Primary: To demonstrate that intensified chemotherapy followed by consolidating high-dose chemotherapy and autologous stem-cell transplantation (HCT-ASCT) is superior to conventional chemotherapy with R-MP followed by maintenance in elderly patients with newly diagnosed PCNSL in terms of progression free survival (PFS). Secondary: To compare quality of life, remission after induction treatment, remission after maintenance treatment (arm A) / consolidation treatment (arm B), event free survival, overall survival and treatment related morbidities (neurotoxicity and adverse events) between both treatment arms.
- Therapeutic confirmatory (Phase III)
