Study to Assess Safety and Tolerability of G17DT in Patients With Colorectal Adenocarcinoma. (CC1A&B)

July 3, 2014 updated by: Cancer Advances Inc.

Phase II, Open Label, Single Center, Two Arm Study Study to Assess the Safety, Tolerance and Efficacy of a 2 mg Dose of G17DT Via Intramuscular Injection in Patients With Advanced Metastatic Colorectal Adenocarcinoma.

Pancreatic, gastric, and colorectal cancers have all been shown to overexpress the gastrin gene and to be sensitive to the trophic effects of the gastrin in animal models. The hypothesis of this study is that G17DT will elicit specific and high-affinity antibodies that will bind gastrin-17, thus preventing the trophic activity of cancer cells.
