20090130133 | IMMUNOGENIC POLYPEPTIDE COMPOSED OF TUMOR ANTIGEN-DERIVED OPTIMIZED CRYPTIC PEPTIDES, AND USES THEREOF - The present invention pertains to the field of anti-cancer vaccines. More particularly, the invention concerns an optimized polypeptide, which comprises three cryptic tumor peptides with enhanced immunogenicity and comprises the amino acids sequence YLQVNSLQTVYLEYRQVPVYLEEITGYL, for use in an anti-cancer vaccine. Nucleic acids encoding such a polypeptide, as well as complexes and dendritic cells engineered with this polypeptide or a nucleic acid encoding it, are also part of the invention. | 05-21-2009 |
20120142894 | Identification, Optimization and Use of Shared HLA-B*0702 Epitopes for Immunotherapy - The present invention provides novel methods and materials for efficiently treating patients having an HLA-B*0702 phenotype, based on peptides representing shared epitopes of tumour antigens. In particular, the invention relates to a method for identifying a HLA-B*0702-restricted peptide which can trigger a cytotoxic response against several antigens from one single multigenic family, and to several such epitopes. | 06-07-2012 |
20130266598 | Identification, Optimization And Use Of Cryptic HLA-B7 Epitopes For Immunotherapy - The invention provides methods for identifying a HLA-B*0702-restricted cryptic epitope in an antigen, as well as methods for increasing the immunogenicity of HLA-B*0702-restricted cryptic epitopes. The HLA-B*0702-restricted cryptic epitopes and their cognate immunogenic epitopes are useful for stimulating an immune reaction against the cryptic epitopes in a subject. Accordingly, the invention further provides pharmaceutical compositions comprising a HLA-B*0702-restricted cryptic epitope or a cognate immunogenic epitope thereof, and vaccination kits comprising such epitopes. The novel materials of the invention are particularly useful for efficiently treating patients having an HLA-B*0702 phenotype. | 10-10-2013 |
20140178421 | Use of Native Peptides and Their Optimized Derivatives For Vaccination - The present invention pertains to the field of vaccination, and more particularly to the fields of antitumor and antiviral vaccination. The invention relates to the use of a native peptide in a medicinal composition, for selecting and/or boosting part of a CTL immune response which has been initiated by an optimized immunogenic peptide derived from said native peptide. The invention also concerns vaccination kits which comprise several doses of optimized peptides and of their cognate native peptides. | 06-26-2014 |

20090175892 | Polynucleotides encoding MHC class I-restricted hTERT epitopes, analogues thereof or polyepitopes - This invention relates to the field of anticancer therapy, and to the identification of immunogenic peptides derived from the human telomerase reverse transcriptase (hTERT). The present invention relates to polynucleotides encoding hTERT epitopes restricted to MHC class I molecule, analogues thereof and polyepitopes containing such epitopes and/or analogues. Are also included in the present invention, vector and cell comprising such polynucleotides. The present invention also concerns composition comprising hTERT polypeptides, corresponding polynucleotides, vectors and cells, for use in the treatment and/or prevention of cancer. | 07-09-2009 |
20090269363 | METHOD FOR SCREENING PEPTIDES FOR USE IN IMMUNOTHERAPY - Identifying subdominant/cryptic epitopes (I) that are presented by a HLA (human leukocyte antigen) Class I molecule, is new. Identifying subdominant/cryptic epitopes (I) that are presented by a HLA (human leukocyte antigen) Class I molecule comprising selecting at least one peptide (II) of 8-11 amino acids (aa), potentially representing an epitope for Class I presentation, from a protein against which a cytotoxic T cell (CTL) response is to be raised. (II) corresponds to a non-immunogenic peptide with low affinity for Class I molecules. Variants (IIa) of (II) are prepared in which the N-terminal aa is replaced by Tyr and their immunogenicity detected by identifying those that generate a CTL response against target cells expressing the parent protein. Peptide sequences from which active (IIa) are derived are then identified. Independent claims are also included for the following: (1) immunogenic peptide epitopes (IIa) derived from (I) identified this way; and (2) nucleic acid (III) that encodes chimeric polypeptides (IV) containing one or more, same or different, copies of (IIa). | 10-29-2009 |
