ClinConnect Summary

This clinical trial is testing a new treatment plan called Rituximab-Methotrexate-Temozolomide-Thiotepa (RMTT) for patients with a type of brain cancer known as primary central nervous system diffuse large B-cell lymphoma (PCNS DLBCL). The goal is to see how effective and safe this treatment is when given as the first option for patients who have just been diagnosed. The trial is currently looking for participants, specifically adults between the ages of 18 and 75 who have not yet received any chemotherapy or similar treatments for their condition.

To be eligible for the trial, participants should have a confirmed diagnosis of PCNS DLBCL and certain measurable lesions in the brain. They should also be in generally good health, with a life expectancy of at least three months. Women of childbearing age need to use effective birth control during the study, and men must agree to do the same. Participants will have the chance to receive this promising treatment and will be closely monitored throughout the trial to ensure their safety. It's important to note that people with certain medical conditions or those who have recently undergone surgery or other treatments may not be eligible to join.
