Indium (111In) capromab pendetide

Indium (¹¹¹In) capromab pendetide (trade name Prostascint) is used to image the extent of prostate cancer. Capromab is a mouse monoclonal antibody which recognizes prostate specific membrane antigen (PSMA) from prostate cancer cells and normal prostate tissue. It is linked to pendetide, a derivative of DTPA. Pendetide acts as a chelating agent for the radionuclide indium-111. Following an intravenous injection of Prostascint, imaging is performed using single photon emission computed tomography (SPECT).

Early trials with yttrium (⁹⁰Y) capromab pendetide were also conducted.
