"ccRCC is the most common type of kidney cancer, and this significant milestone underscores our commitment to advancing innovative treatments to these patients as quickly as possible."

Fast Track Designation is a process designed to facilitate development and expedite the review of drugs intended to treat serious conditions and fill an unmet medical need.

About ADI-270

ADI-270 is an armored allogeneic "off-the-shelf" gamma delta CAR T cell therapy candidate targeting CD70-positive cancers. CD70 is a compelling target due to its high expression in both solid and hematological malignancies. ADI-270 is engineered with a third-generation CAR designed to target CD70 using its natural receptor, CD27, as the binding moiety and is further armored with a dominant negative form of the transforming growth factor-β receptor II (dnTGFβRII) to provide functional resilience to the immunosuppressive tumor microenvironment. ADI-270 is also designed to increase exposure and persistence by reducing susceptibility to host vs. graft elimination. These properties of ADI-270 combined with the potent tumor infiltration demonstrated with gamma delta 1 T cells aim to improve clinical responses of RCC patients and other patients with CD70+ tumors.
