- Conditions
- Central Nervous System Lymphoma

- Registration Number
- NCT04938297
- Lead Sponsor
- Henan Cancer Hospital
- Brief Summary
In view of the synergistic effects of rituximab, zanubrutinib, and lenalidomide and severe complications caused by current standard chemotherapy regimens in Patients for primary or secondary CNS lymphoma, we intend to conduct a prospective clinical study to evaluate the efficacy and toxicity of Rituximab, Zanubrutinib in combination with Lenalidomide. Besides, the efficacy of Zanubrutinib or Lenalidomide in maintenance was also compared.
