Indication: Intended for the treatment of various forms of cancer.
Pharmacodynamics: Not Available
Mechanism of action: When administered, G17DT induces an immune response producing antibodies which bind with the peptide and also cross-react and neutralise gastrin 17 thus inhibiting the growth of gastrointestinal cancers and metastasis. In addition the product neutralizes glycine-extended gastrin 17 which is also a stomach and pancreatic cancer growth factor.
