A pilot study of the immunogenicity of a 9-peptide breast cancer vaccine plus poly-ICLC in early stage breast cancer.

Background: Breast cancer remains a leading cause of cancer death worldwide. There is evidence that immunotherapy may play a role in the eradication of residual disease. Peptide vaccines for immunotherapy are capable of durable immune memory, but vaccines alone have shown sparse clinical activity against breast cancer to date.

Survivorship Care Plans: Rural, Low-Income Breast Cancer Survivor Perspectives.

Background: Despite increasing implementation of survivorship care plans (SCPs), cancer survivors still experience unmet needs post-treatment. Rural, low-income survivors experience less planning for supportive care during treatment, which is difficult to overcome after patients complete treatment.

Immunogenicity for CD8+ and CD4+ T cells of 2 formulations of an incomplete freund's adjuvant for multipeptide melanoma vaccines.

An incomplete Freund's adjuvant (IFA) commonly used in experimental cancer vaccines has recently been reformulated. Oleic acid used in the surfactant was purified from a vegetable source (olives, IFA-VG) rather than an animal source (beef tallow, IFA-AN). To provide an insight into the adjuvant properties of the new formulation, we reviewed T-cell responses, by enzyme-linked immunospot assay, to multipeptide vaccines in 2 sequential clinical trials that spanned this transition of adjuvants.

Helper T-cell responses and clinical activity of a melanoma vaccine with multiple peptides from MAGE and melanocytic differentiation antigens.

Purpose: A phase I/II trial was performed to evaluate the safety and immunogenicity of a novel melanoma vaccine comprising six melanoma-associated peptides defined as antigenic targets for melanoma-reactive helper T cells. Source proteins for these peptides include MAGE proteins, MART-1/MelanA, gp100, and tyrosinase.

Patients And Methods: Thirty-nine patients with stage IIIB to IV melanoma were vaccinated with this six-peptide mixture weekly at three dose levels, with a preceding phase I dose escalation and subsequent random assignment among the dose levels.

A multipeptide vaccine is safe and elicits T-cell responses in participants with advanced stage ovarian cancer.

Nine participants with epithelial ovarian, fallopian tube, or primary peritoneal carcinoma, who were human leukocyte antigen (HLA)-A1, HLA-A2, or HLA-A3, were eligible to enroll in a phase 1 study designed to assess the safety and immunogenicity of a peptide-based vaccine. Participants received 5 class I major histocompatibility complex-restricted synthetic peptides derived from multiple ovarian cancer-associated proteins plus a class II major histocompatibility complex-restricted synthetic helper peptide derived from tetanus toxoid protein. The vaccines were administered with granulocyte macrophage-colony stimulating factor in Montanide ISA-51 adjuvant over a 7-week period.
