Dose-ranging Study to Evaluate Antibody Response to G17DT in Patients With Gastric Cancer

August 10, 2015 updated by: Cancer Advances Inc.

An Open, Dose-ranging, Multicenter Study to Determine the Antibody Response to G17DT and Its Safety and Tolerability in the Treatment of Patients With Gastric Cancer

An open, dose-ranging, multiple dose, multi-centre study in patients with Stage I-III or Stage IV gastric cancer. Twelve patients in each of 5 treatment groups were to receive three injections at weeks 0, 2 and 6 with provision for a single booster injection in an extension study period.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Measurable Antibody Titer
Time Frame: Up to Week 12
Up to Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival from date of randomization to death or end of study
Time Frame: Up to Last Patient Last Visit, January 2001
Patients were scheduled to attend follow-up visits every four weeks after completion of the 12-week core period of the study and to continue until the patient was discharged from the study or declined further follow-up.
Up to Last Patient Last Visit, January 2001
Injection Site Reaction
Time Frame: Through Week 12
A physical examination for the presence of an abcess at the injection site was performed on each patient to assess tolerability to treatment at every posttreatment visit from Week 0 to Week 12.
Through Week 12

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
