Tumor Vaccine and Interferon Gamma in Treating Patients With Refractory Epithelial Ovarian Cancer

2014-08-27 03:58:25 | BioPortfolio

Summary

RATIONALE: Vaccines made from a person's cancer cells may make the body build an immune response to and kill their tumor cells. Combining vaccine therapy with interferon gamma may be a more effective treatment for epithelial ovarian cancer.

PURPOSE: Phase I trial to study the effectiveness of a tumor cell vaccine and interferon gamma in patients with refractory epithelial ovarian cancer.

Description

OBJECTIVES:

- Determine whether intraperitoneal (IP) injections of epithelial ovarian carcinoma cells infected with ALVAC-hB7.1 and IP interferon gamma have acceptable toxicity and produce any clinical responses in patients with refractory ovarian epithelial cancer.

OUTLINE: This is a dose-escalation study of ALVAC-hB7.1 infected tumor cells.

Patients receive ALVAC-hB7.1 infected tumor cells intraperitoneally (IP) on days 4, 11, and 18. Patients also receive interferon gamma IP on days 8, 10, 15, and 17. In the absence of disease progression, up to 6 courses of therapy may be given. If insufficient tumor cells are available to continue treatment with tumor cell derived vaccine, interferon gamma may be given alone.

Cohorts of 3 to 6 patients receive escalating doses of ALVAC-hB7.1 infected tumor cells until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 2 of 6 patients experience dose-limiting toxicity.

Patients are followed every 6 months until disease progression.

PROJECTED ACCRUAL: A total of 12 patients will be accrued for this study.

Medical and Biotech [MESH] Definitions

The assay of INTERFERON-GAMMA released from lymphocytes after their exposure to a specific test antigen, to check for IMMUNOLOGIC MEMORY resulting from a previous exposure to the antigen. The amount of interferon-gamma released is usually assayed by an ENZYME-LINKED IMMUNOSORBENT ASSAY.

A type II interferon produced by recombinant DNA technology. It is similar to the interferon secreted by lymphocytes and has antiviral and antineoplastic activity.

The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.

An interferon regulatory factor that recruits STAT1 PROTEIN and STAT2 PROTEIN heterodimers to interferon-stimulated response elements and functions as an immediate-early protein.

A multimeric complex that functions as a ligand-dependent transcription factor. ISGF3 is assembled in the CYTOPLASM and translocated to the CELL NUCLEUS in response to INTERFERON signaling. It consists of ISGF3-GAMMA and ISGF3-ALPHA, and it regulates expression of many interferon-responsive GENES.
