ClinConnect Summary

This clinical trial is studying a combination of three medications—rituximab, zanubrutinib, and lenalidomide—to see how well they work together in treating patients with central nervous system lymphoma. This type of lymphoma affects the brain and spinal cord, and the trial aims to find a safer and more effective treatment option than the current standard therapies, which can cause severe side effects. After the initial treatment, the study will also compare the effectiveness of continuing treatment with either zanubrutinib or lenalidomide.

To participate in this trial, patients must be at least 18 years old and have a confirmed diagnosis of a specific type of lymphoma. They should be willing to follow all study procedures and provide necessary tissue samples. The trial is open to patients who have not responded to previous treatments or who cannot tolerate standard therapies, particularly those aged 65 and older. Participants can expect to receive careful monitoring throughout the study, including assessments of how the treatment affects their health and any potential side effects. It's important for interested patients to discuss the trial with their healthcare provider to see if they meet the eligibility criteria and to understand the procedures involved.
