Description Gallium (Ga) 68 prostate-specific membrane antigen (PSMA)-11, or Ga-68 gozetotide, is a radiopharmaceutical agent used to identify and assess prostate-specific membrane antigen (PSMA)-positive lesions in adult men with prostate cancer during positron emission tomography (PET).[L26981] Prostate cancer is one of the most commonly diagnosed cancers among men in Western countries and many patients treated with androgen-deprivation therapy relapse with castration-resistant prostate cancer.[A225396] In nearly all prostate cancers, malignant cells express a transmembrane protein called prostate-specific membrane antigen (PSMA).[A225396] Ga-68 PSMA-11 is an imaging agent that binds PSMA during positron emission tomography: it emits positrons to indicate the presence of PSMA-positive prostate cancer lesions in patients with suspected prostate cancer or in patients who may have recurrent prostate cancer.[L27006] On December 1, 2020, Ga-68 PSMA-11 was approved by the FDA as the first molecular-targeted drug for positron emission tomography (PET) imaging of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer.[L27006] It is administered intravenously. In October 2022, the EMA's Committee for Medicinal Products for Human Use (CHMP) recommended Ga-68 gozetotide be granted marketing authorization for the diagnosis of prostate cancer.[L43542]
