Vaccine Therapy in Treating Patients With Stage III-IV or Recurrent Ovarian Cancer

February 22, 2021 updated by: University of Washington

A Phase I Trial of the Safety and Immunogenicity of a DNA Plasmid Based Vaccine Encoding the Amino Acids 1-163 of Insulin-Like Growth Factor Binding Protein-2 (IGFBP-2) in Patients With Advanced Ovarian Cancer

This phase I trial is studying the side effects of vaccine therapy in treating patients with stage III-IV or recurrent ovarian cancer. Vaccines made from deoxyribonucleic acid (DNA) may help the body build an effective immune response to kill tumor cells.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the safety of an insulin like growth factor binding protein 2 (IGFBP-2) Th polyepitope plasmid based vaccine in patients with advanced stage or recurrent ovarian cancer.

SECONDARY OBJECTIVES:

I. To determine the immunogenicity of IGFBP-2 Th polyepitope plasmid based vaccine in patients with advanced stage or recurrent ovarian cancer.

II. To determine whether intermolecular epitope spreading occurs with the generation of an IGFBP-2 specific Th1 immune response.

III. To determine whether IGFBP-2 vaccination modulates T regulatory cells.

OUTLINE:

Patients receive pUMVC3-hIGFBP-2 multi-epitope plasmid DNA vaccine intradermally (ID) monthly for 3 months.

After completion of study treatment, patients are followed up at 1, 3, 6, and 12 months, and then every 6 months for 5 years.

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.

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.

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
Measure Description
Time Frame
Safety as assessed per Cancer Therapy Evaluation Program (CTEP) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0
Time Frame: Up to 16 months
Demographic and background characteristics obtained at enrollment will be listed and summarized. The type and grade of toxicities noted during the immunization regimen will be summarized. All adverse events noted by the investigator will be tabulated according to the affected body system. Descriptive statistics will be used to summarize changes from baseline in clinical laboratory parameters.
Up to 16 months

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
Immunogenicity, via cellular immune response and humoral immune response, as assessed by the generation of IGFBP-2 specific T cells and IgG antibodies
Time Frame: Up to 16 months
Cellular immune response will be defined by the magnitude of the Th1 antigen specific immune response using IFN-gamma enzyme-linked immunosorbent spot (ELISPOT). Humoral immune response will be measured by enzyme-linked immunosorbent assay (ELISA) and serum antibody avidity for IGFBP-2 using ELISA to determine an avidity index (AI) before and after vaccination. Spearman's correlation coefficient will be used to estimate the correlation between two continuous measures.
Up to 16 months
Epitope spreading with the generation of an IGFBP-2 Th1 immune response
Time Frame: Up to 16 months
Peripheral blood mononuclear cells (PBMC) will be assessed by ELISPOT for immunity to a panel of immunogenic ovarian cancer related proteins: topoisomerase II-alpha (a), p53, IGF-IR, FASCIN-1, and MMP-7. Epitope spreading will have been considered to occur if new immune responses are generated to any of these antigens during the course of the study. In addition, epitope spreading and T regulatory cells will be defined as present or absent, and the probability of each will be estimated as a simple proportion as above with toxicity.
Up to 16 months
Levels of regulatory T- cells (Tregs) over the course of immunization to detect modulation of Tregs with vaccination
Time Frame: Up to 16 months
Assessed by flow cytometry of PBMC. In addition, epitope spreading and T regulatory cells will be defined as present or absent, and the probability of each will be estimated as a simple proportion as above with toxicity.
Up to 16 months
Disease-free survival
Time Frame: Up to 5 years
A questionnaire will be sent to the patient's primary oncologist requesting laboratory evaluation of toxicity, CA-125, and the patient's disease free and overall survival status.
Up to 5 years
Overall survival
Time Frame: Up to 5 years
A questionnaire will be sent to the patient's primary oncologist requesting laboratory evaluation of toxicity, CA-125, and the patient's disease free and overall survival status
Up to 5 years
