Cellectis has developed genome editing technology TALEN, which enables it to create more affordable, ready-to-use allogeneic CAR T-cell therapies. Its technology offers protection against graft-versus-host disease, reduces the risk of rejection and improves safety by integrating a self-destruct mechanism. Using this technology, the company is developing a pipeline of several candidates against non-Hodgkin's lymphoma, large B-cell lymphoma, renal cell carcinoma and melanoma. Cellectis is also advancing PulseAgile technology, which uses electroporation (controlled electric fields) to deliver messenger RNA molecules into cells. It utilizes a unique electric field waveform, which, combined with a proprietary buffer solution, allows molecules such as nucleases to effectively penetrate cells while maintaining high cell viability.
