Single Centre Study to Determine the Antibody Response to G17DT in Patients With Advanced Pancreatic Cancer.
- Registration Number
- NCT02098239
- Lead Sponsor
- Cancer Advances Inc.
- Brief Summary
The study was designed to assess the effect of jaundice on the ability of G17DT to generate antibodies before and after treatment of biliary obstruction due to advances pancreatic cancer.
- Detailed Description
Jaundiced patients with advanced pancreatic cancer (either locally, advanced or metastatic) were treated with G17DT either immediately (Group A), or following biliary stenting when jaundice had resolved (Group B). Patients not jaundiced at time of presentation were to enter Group B. Patients received 3 Intramuscular injections of G17DT at weeks 0, 1, and 3. A booster injection was offered to patients who had measurable anit-G17Dt antibodies but had anti-G17DT antibodies that fell below a pre-specified threshold after week 23. Patients were evaluated until study closure ort until patient death.

- Arm && Interventions
Group Intervention Description Group A G17DT Jaundiced patients with bilirubin value \>80 μmol/L. Received G17DT immediately prior to biliary stenting. Group B G17DT Patients to be treated following biliary decompression or for immediate treatment if non-jaundiced. Received G17DT 2 weeks after biliary stenting when bilirubin was \<40 μmol/L.
- Primary Outcome Measures
Name Time Method Patient Survival Up to week 139 The vital status of patients was monitored throughout the study and was followed until death or the end of the study.
Pharmacodynamic Weeks 0, 1,3,4,6,8,12, 16+ Gastrin-17 antibodies were measured at baseline (Week 0) and measured at each post-treatment visit.
- Secondary Outcome Measures
Name Time Method Injection Tolerability Up to Week 16 Tolerability was assessed by injection site during first 16 weeks after the first injection.
