This clinical trial is focused on studying a type of cancer called follicular lymphoma, which is a form of non-Hodgkin lymphoma affecting the lymphatic system. The trial is specifically for adult patients whose disease has returned or has not responded to at least two previous treatments. The main treatment being tested in this study is called tisagenlecleucel, also known by its code name CTL019. This is a type of cell therapy that uses the patient’s own immune cells, which are modified to better fight cancer. The study will compare the effectiveness of tisagenlecleucel with the standard treatments currently used for this condition.
Participants in the study will receive either tisagenlecleucel or one of the standard treatments, which may include medications like rituximab, cyclophosphamide monohydrate, doxorubicin hydrochloride, vincristine sulfate, prednisone, prednisolone, fludarabine phosphate, lenalidomide, bendamustine hydrochloride, or tocilizumab. Some participants may receive a placebo. The purpose of the study is to determine if tisagenlecleucel can improve the time patients live without their disease getting worse, which is known as progression-free survival.
The study will involve regular visits to the clinic for treatment and monitoring. Participants will undergo various tests and assessments to track their health and the progress of their disease. The trial will last for several years, with the aim of gathering comprehensive data on the safety and effectiveness of tisagenlecleucel compared to standard treatments. This information will help determine the best treatment options for patients with relapsed or refractory follicular lymphoma.
