RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Giving a vaccine with Montanide ISA-51 and sargramostim may cause a stronger immune response and kill more tumor cells.
- Determine the safety of telomerase: 540-548 peptide vaccine emulsified in Montanide ISA-51 and sargramostim (GM-CSF) in patients with HLA-A2-expressing stage IV breast cancer.
- Compare the generation of human telomerase reverse transcriptase (hTERT) peptide-specific vs cytomegalovirus peptide-specific cytotoxic T-lymphocyte (CTL) immunity in patients treated with this regimen.
- Correlate the dose level of this regimen with the generation of hTERT-specific CTL immunity and the development of hTERT-specific autoimmunity in these patients.
- Determine the tumor response in patients treated with this regimen.
OUTLINE: This is a dose-escalation study of the telomerase: 540-548 peptide and CMV 495 peptide portions of the vaccine.
Patients receive telomerase: 540-548 peptide and CMV 495 peptide (as an immunological control) vaccine emulsified in Montanide ISA-51 subcutaneously (SC) followed by sargramostim (GM-CSF) SC on day 1 of weeks 1, 3, 5, 7, 11, 15, 19, and 27 (for a total of 8 vaccinations). Treatment continues in the absence of disease progression or unacceptable toxicity.
Cohorts of 5-8 patients receive escalating doses of telomerase: 540-548 peptide and CMV 495 peptide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 5 or 2 of 8 patients experience dose-limiting toxicity. A total of 12 patients receive treatment at the MTD.
Patients are followed within 30 days and then at 6 and 12 months.
PROJECTED ACCRUAL: A total of 5-28 patients will be accrued for this study.

Current vaccine research has shifted from traditional vaccines (i.e., whole-killed or live-attenuated) to subunit vaccines (i.e., protein, peptide, or DNA) as the latter is much safer due to deliverin...
Vaccination with MHC-II-restricted peptides from Apolipoprotein B (ApoB) with complete and incomplete Freund's adjuvant (CFA/IFA) is known to protect mice from atherosclerosis. This vaccination induce...
Proteus mirabilis is a common pathogen in urinary tract infections (UTIs). There is no vaccine against P. mirabilis, thus a novel multi-peptide vaccine of MrpA, UcaA and Pta factors of P. mirabilis we...
Vulvodynia is a prevalent chronic pain disorder associated with high medical costs and often ineffective treatments. The major pathological feature is proliferation of vaginal nerve fibres. This study...
Propranolol (Pro), a non-specific β-adrenergic blocking drug, competitively prevents the binding of catecholamines to receptors and suppresses cancer cells. The anti-tumor activity of propranolol has...
An antigen solution emulsified in mineral oil. The complete form is made up of killed, dried mycobacteria, usually M. tuberculosis, suspended in the oil phase. It is effective in stimulating cell-mediated immunity (IMMUNITY, CELLULAR) and potentiates the production of certain IMMUNOGLOBULINS in some animals. The incomplete form does not contain mycobacteria.
A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.
A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)
A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.
A fluid-filled closed cavity or sac that is lined by an EPITHELIUM and found in the BREAST. It may appear as a single large cyst in one breast, multifocal, or bilateral in FIBROCYSTIC BREAST DISEASE.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one ...
