Summary

This trial aims to assess the effectiveness and safety of using cemacabtagene ansegedleucel (cema-cel), a type of immunotherapy, in adult patients with large

Who is the study for?
This trial is for adults with large B-cell lymphoma (LBCL) who've had a complete or partial response to first-line therapy but still have minimal residual disease (MRD). They must be suitable for observation and have MRD detected by the Foresight CLARITY™ IUO MRD test.
What is being tested?
The study tests cemacabtagene ansegedleucel (cema-cel), a CD19 CAR T cell therapy, after standard chemo drugs fludarabine and cyclophosphamide, with or without ALLO-647. It compares this treatment's effectiveness and safety against just observing patients.
What are the potential side effects?
Possible side effects include reactions from the infusion of cema-cel, such as fever, fatigue, immune system complications, and potential toxicity from chemotherapy like nausea or low blood counts.
