ClinConnect Summary

This clinical trial is studying a new treatment combination for patients with untreated EBV-positive diffuse large B-cell lymphoma (DLBCL), a type of blood cancer. The researchers want to see how well the drug selinexor works when given alongside a standard treatment called R-CHOP, which includes several medications to help fight the cancer. After the initial treatment, patients will continue taking selinexor on its own to see if it helps keep the cancer from coming back.

To be eligible for this trial, participants need to be between 18 and 70 years old and must have a confirmed diagnosis of EBV-positive DLBCL. They should not have received any previous treatments for their cancer, except for a short use of prednisone to manage symptoms. Participants will undergo regular check-ups to monitor their health and the effectiveness of the treatment. This trial is currently recruiting participants, and anyone interested should discuss it with their healthcare provider to see if they qualify.
