Research summary
Richter transformation (RT) is a type of aggressive lymphoma which can develop in patients with a previous or concurrent diagnosis of chronic lymphocytic leukaemia (CLL). It is predominantly seen in adults.
The standard therapies that are currently available to treat the disease have limited effectiveness. The purpose of this study is to find out if the experimental treatment, brexu-cel, is safe and effective in treating Richter transformation. Approximately 60 participants will take part globally.
Immunotherapy is a type of therapy that uses the body’s own immune system to target the tumour. Brexu-cel is manufactured using the patient’s own white blood cells. If patients meet study eligibility criteria they will undergo a procedure known as leukapheresis, this involves removing white blood cells from the blood. These cells are then modified so that they can more effectively identify and destroy tumour cells, and then returning those modified cells back to the patient via intravenous (IV) infusion and assessing the effect on their cancer cells. Prior to the infusion participants will undergo lymphodepleting chemotherapy in order to help brexu-cel work with less interference from the cells in the immune system. Patients must remain in hospital for 10 days following their infusion.
The study is open label meaning the treatment is known to both the study doctor and participant.
The study can be broken down into six sections: screening, enrolment and leukapheresis, optional bridging therapy, lymphodepleting chemotherapy, treatment and post-treatment follow up. Participants will be followed up within the study for a duration of 24 months.Assessments to determine how participants are responding to treatment will occur at Day 28, Month 3 and then every 3 months up to Month 12, followed by every 6 months up to Month 24.
