Psma-hbed-cc ga-68
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). 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. In nearly all prostate cancers, malignant cells express a transmembrane protein called prostate-specific membrane antigen (PSMA). 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.   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. 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.
