Summary

The purpose of this study is to determine the efficacy and safety of the new treatment proposed in this study. Conducting a prospective study "CNS-2015" in patients with PDLBCL CNS made it possible to achieve 2-year EFS, DFS and OS of 83%, 83% and 88%, respectively. The presence of early relapses of the disease has now led to the need to find an alternative program for patients with PDLBCL CNS. In the new "CNS-2021" protocol, lenalidomide was included in the R-MPV program in order to intensify the induction stage. In the conditioning regimen, thiotepa was replaced by carmustine, due to its significant CNS bioavailability. In order to possibly prevent early relapses, an anti-PD-1 inhibitor (nivolumab) was used as maintenance therapy.

Conditions

  • Primary CNS Lymphoma

Interventions

DRUG

Rituximab, Methotrexate, Vincristine, Procarbazine, Lenalidomide

The initial treatment will consist of cycles of 14 days. Each cycle will start with rituximab, which will be given by vein on day 1. On day 2 you will receive: Methotrexate will be given by vein over 2 to 3 hours and vincristine will be given as a single injection over a few minutes. Procarbazine and Lenalidomide are a pill that you will take at bedtime for 7 nights starting on day 2. Procarbazine and Lenalidomide are only given every other cycle. During each cycle, you will be in the hospital. After the second cycle of chemotherapy, PBPCs will be collected. You will be hospitalized again for high-dose chemotherapy and receive supportive medications to help avoid complications, including antibiotics and blood transfusions. Busulfan, carmustine and cyclophosphamide will be given to you for 5 days. After break of 1 day, we will return your PBPC (or bone marrow) to you through a vein. You will be in the hospital for at least 3 weeks.
