PNT2004 is a radioligand that targets Fibroblast Activation Protein-α (FAP-α), which is highly expressed on a wide range of solid tumors, but absent in all other healthy tissues.

Invented by Dr. William Bachovchin at Tufts University, PNT2004 offers the potential for a tissue agnostic opportunity that could enable the precise treatment of a variety of solid tumors independent of tissue origin.
