Study to Determine the Antibody Response to 500µg G17DT in Treatment of Patients With Gastric Cancer
- Conditions
- Gastric Cancer
- Interventions
- Biological: G17DT
- Registration Number
- NCT02450032
- Lead Sponsor
- Cancer Advances Inc.
- Brief Summary
This study was designed to investigate the antibody response generated by a 500µg dose of G17DT in patients with gastric cancer.
- Detailed Description
Another study, GC2, initiated prior to the start of this study investigated the appropriate dose and dosing schedule for G17DT in patients with Stage I-III gastric cancer. The highest dose tested in the GC2 study was 250µg. This dose was well tolerated but was not considered sufficiently immunogenic. Since tolerability had not constrained dosing up to 250µg, the GC5 study was designed to investigate a 500µg dose administered as a regimen of 0, 2, and 6 weeks.

Group Intervention Description G17DT G17DT Treatment with 500µg/ 0.4mL dose of G17DT administered by intramuscular injection at 0, 2, and 6 weeks.
- Primary Outcome Measures
Name Time Method Antibody Levels Through Week 12 Gastrin-17 antibodies are produced as a result of treatment with G17DT and the proportion of patients producing gastrin-17 antibodies was considered to be an appropriate measure of the immunogenicity of the dosing schedule under study.
Injection Site Reaction Up to Week 12 A physical examination for the presence of an abscess at the injection site was performed on each patient to assess tolerability to treatment at every posttreatment visit from Week 0 to Week 12.
Change in Subject's World Health Organization Performance Status Through Week 12 The subject's WHO performance status was evaluated at each visit up to Week 12 to assess changes in subject's ability complete normal daily activities.
- Secondary Outcome Measures
Name Time Method Overall Survival From date of randomization up to Week 24 or until death Vital status was monitored throughout the study. Patients were followed up to their death or the study completion date, 18 June 2001.
Adverse Events Through week 12 All adverse events reported during the study.
