Vaccine Therapy in Treating Women With Triple-Negative Breast Cancer

2014-08-27 03:18:58 | BioPortfolio

Summary

RATIONALE:

Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. Giving booster vaccinations may make a stronger immune response and prevent or delay the recurrence of cancer.

PURPOSE:

This clinical trial is studying the side effects and how well vaccine therapy works in treating women with triple-negative breast cancer.

Description

PRIMARY OBJECTIVES:

I. To evaluate the efficacy of MUC1 peptide-poly-ICLC adjuvant vaccine in boosting systemic immunity to MUC1 in women who have completed therapy for AJCC stage I-III 'triple-negative' [i.e., ER(-) PR(-) HER2/neu(-)] breast cancer.

SECONDARY OBJECTIVES:

I. To evaluate the safety and toxicity of the MUC1 peptide and poly-ICLC vaccine in this cohort of patients.

OUTLINE:

Patients receive MUC-1 peptide vaccine subcutaneously and poly-ICLC vaccine intramuscularly in weeks 0, 4, 8, 12, 52, and 56 in the absence of disease progression or unacceptable toxicity. Patients may receive additional vaccines in weeks 34 and 38 if anti-MUC1 immunity falls below the two-fold enhancement from baseline.

Medical and Biotech [MESH] Definitions

A poly(A) binding protein that is involved in promoting the extension of the poly A tails of MRNA. The protein requires a minimum of ten ADENOSINE nucleotides in order for binding to mRNA. Once bound it works in conjunction with CLEAVAGE AND POLYADENYLATION SPECIFICITY FACTOR to stimulate the rate of poly A synthesis by POLY A POLYMERASE. Once poly-A tails reach around 250 nucleotides in length poly(A) binding protein II no longer stimulates POLYADENYLATION. Mutations within a GCG repeat region in the gene for poly(A) binding protein II have been shown to cause the disease MUSCULAR DYSTROPHY, OCULOPHARYNGEAL.

A poly(ADP-ribose) polymerase that contains two ZINC FINGERS in its N-terminal DNA-binding region. It modifies NUCLEAR PROTEINS involved in chromatin architecture and BASE EXCISION REPAIR with POLY ADENOSINE DIPHOSPHATE RIBOSE.

A poly(A) binding protein that has a variety of functions such as mRNA stabilization and protection of RNA from nuclease activity. Although poly(A) binding protein I is considered a major cytoplasmic RNA-binding protein it is also found in the CELL NUCLEUS and may be involved in transport of mRNP particles.

The addition of a tail of polyadenylic acid (POLY A) to the 3' end of mRNA (RNA, MESSENGER). Polyadenylation involves recognizing the processing site signal, (AAUAAA), and cleaving of the mRNA to create a 3' OH terminal end to which poly A polymerase (POLYNUCLEOTIDE ADENYLYLTRANSFERASE) adds 60-200 adenylate residues. The 3' end processing of some messenger RNAs, such as histone mRNA, is carried out by a different process that does not include the addition of poly A as described here.

Chemicals and drugs that inhibit the action of POLY(ADP-RIBOSE)POLYMERASES.
