US Experimental Intramuscular 5 Clinical Trials
Gastrin-17

Description

G17DT is a therapeutic cancer vaccine that targets gastrin-17, a hormone frequently overexpressed in colorectal cancer cells. This immunotherapy works by stimulating the patient's immune system to produce antibodies against gastrin-17, thereby blocking growth signals that promote tumor progression. G17DT has been evaluated in metastatic colorectal cancer both as monotherapy and in combination with chemotherapy agents like irinotecan.

Mechanism of Action

G17DT consists of gastrin-17 conjugated to diphtheria toxoid, which acts as an immunological carrier to enhance the immune response. When administered, it induces the formation of antibodies against gastrin-17, neutralizing this growth hormone and potentially reducing tumor cell proliferation and angiogenesis in gastrin-17 expressing colorectal cancers.
