Carbonic anhydrase-9 (CA9) is highly expressed in clear cell renal cell carcinoma but not in normal kidney tissues. CA9-targeted photoimmunotherapy was developed by conjugating IR700 to CA9-antibody and using ML7710 for drug activation. In vitro, it showed cell membrane damage and cell killing across multiple renal cancer cell lines. In vivo, PIT prolonged survival and 70-80% of mice achieved a complete remission after a single PIT session.
