personalized medicine using synthetic peptides
Interest in personalized treatment has been fuelled by the concept of tailoring therapy with the best response and highest safety margin to ensure better patient care. Personalized medicine holds promise for improving health care while also lowering costs.
Synthetic Peptides for Personalized Treatment
An immunogenic personal neoantigen vaccine for melanoma patients using synthetic peptides provides an opportunity to develop agents targeted to patient groups that do not respond to medications as intended and for whom the traditional health systems have otherwise failed.
The T cell epitopes with tumor-specific expression arising from non-silent somatic mutations are not expressed in normal tissues. These neoantigens are mutated peptides with the high-affinity binding of autologous HLA molecules.
The vaccination with neoantigens can induce new T cell specificities in cancer patients. Using the synthetic peptides as a personalized vaccine, researchers found that of 6 vaccinated patients, 4 had no recurrence at 25 months post-vaccination.
The T cells discriminated mutated from wild-type peptide antigens and directly recognized autologous tumors. Based on HLA binding predictions, immunizing peptides were selected from this study. Each patient received up to 20 long peptides in 4 pools.
