DescriptionCapromab is a Murine IgG1 monoclonal 7E11-C5.3 antibody that recognizes prostate specific membrane antigen (PSMA – also known as glutamate carboxypeptidase 2) 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. Capromab is used to image the extent of prostate cancer.

IndicationFor diagnosis of prostate cancer and detection of intra-pelvic metastases.
Structured Indications
PharmacodynamicsBinds to the prostate-specific membrane antigen, which is a cell surface protein generally overexpressed in prostate tissues and prostate cancers. The radioactive Indium 111, which is covalently attached to the antibody, allows radiodiagnostic detection of PSMA expressing cells and tumors.
Mechanism of actionBinds selectively to cell-surface prostate-specific membrane antigen (PSMA) expressed on prostate tissues and tumors.

Pharmacological action
General Function:
Tetrahydrofolyl-poly(glutamate) polymer binding
Specific Function:
Has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity. Has a preference for tri-alpha-glutamate peptides. In the intestine, required for the uptake of folate. In the brain, modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate. Isoform PSM-4 and isoform PSM-5 would...
