This clinical trial focuses on the long-term follow-up of patients who have previously been treated with a special type of therapy called CAR T cell therapy. This therapy involves using a patient’s own T cells, which are a type of immune cell, that have been genetically modified to better fight certain diseases. The diseases being studied in this trial are potential cancers that may develop in patients who have received this therapy. The main goal of the study is to monitor the long-term safety of these treatments.
The study involves two specific treatments: AUTO1 and AUTO4, both of which are types of CAR T cell therapies. These treatments are given through an intravenous infusion, which means they are delivered directly into the bloodstream through a vein. Another treatment involved in the study is rituximab, known by the brand name MabThera, which is also given as an infusion. Rituximab is a medication that targets specific proteins on the surface of certain cells and is used in various conditions, including some types of cancer.
During the course of the study, participants will be monitored for any serious side effects related to the CAR T cell therapy, the development of new cancers, and other specific health events of interest. The study will also track overall survival rates and the duration of any supportive care needed. Additionally, researchers will look for any remaining genetic material from the therapy in the blood and check for any potential causes of new cancers. This follow-up will continue for up to 15 years after the initial CAR T cell therapy infusion.
