ClinConnect Summary

This clinical trial is studying a new treatment approach for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), a type of blood cancer that has not responded to previous treatments. The trial focuses on finding the maximum safe dose of a drug called E7777, which is given before a chemotherapy treatment and Kymriah, a specific type of CAR-T therapy. This study is particularly aimed at patients who are at a higher risk of not responding well to CAR-T therapy because of their disease characteristics.

To participate in this trial, you must be at least 18 years old, have a diagnosis of DLBCL that hasn’t responded to other treatments, and meet certain health criteria, such as having sufficient organ function and a good performance status. Participants will receive E7777 followed by chemotherapy, and then Kymriah. Throughout the trial, you can expect regular health check-ups to monitor your response to the treatment and manage any side effects. It’s important to note that participants should have insurance coverage for Kymriah and agree to use birth control if they are of childbearing potential.
