Title (EN) LISTERIA-BASED IMMUNOGENIC COMPOSITIONS COMPRISING HETEROCLITIC WILMS TUMOR PROTEIN ANTIGENS AND METHODS OF USE THEREOF
(FR) COMPOSITIONS IMMUNOGÈNES À BASE DE LISTERIA COMPRENANT DES ANTIGÈNES DE PROTÉINE TUMORALE DE WILMS HÉTÉROCLITIQUE ET PROCÉDÉS D'UTILISATION CORRESPONDANTS
Abstract:
(EN) Provided herein are recombinant fusion polypeptides comprising one or more antigenic Wilms tumor protein (WT1) peptides, wherein at least one of the antigenic WT1 peptides is a heteroclitic mutant WT1 peptide (e.g., fused to a PEST-containing peptide). Also provided are nucleic acids encoding such fusion polypeptides, recombinant bacteria or Listeria strains comprising such fusion polypeptides or such nucleic acids, and cell banks comprising such recombinant bacteria or Listeria strains. Also provided herein are methods of generating such fusion polypeptides, such nucleic acids, and such recombinant bacteria or Listeria strains. Also provided are immunogenic compositions, pharmaceutical compositions, and vaccines comprising such fusion polypeptides, such nucleic acids, or such recombinant bacteria or Listeria strains. Also provided are methods of inducing an anti-WT1 immune response in a subject, methods of inducing an anti-WT1-expressing-tumor or anti-WT1-expressing-cancer immune response in a subject, methods of treating a WT1-expressing or WT1-associated tumor or cancer in a subject, methods of preventing a WT1-expressing or WT1-associated tumor or cancer in a subject, and methods of protecting a subject against a WT1-expressing or WT1-associated tumor or cancer using such recombinant fusion polypeptides, nucleic acids, recombinant bacteria or Listeria strains, immunogenic compositions, pharmaceutical compositions, or vaccines.
(FR) L'invention concerne des polypeptides de fusion recombinants comprenant un ou plusieurs peptides de protéine tumorale de Wilms (WT1) antigéniques, au moins l'un des peptides WT1 antigéniques étant un peptide WT1 mutant hétéroclitique (par exemple fusionné en peptide contenant du PEST). La présente invention concerne également des acides nucléiques codant pour de tels polypeptides de fusion, des bactéries recombinantes ou des souches de Listeria comprenant de tels polypeptides de fusion ou de tels acides nucléiques, et des banques cellulaires comprenant de telles bactéries recombinantes ou souches de Listeria. La présente invention concerne également des procédés de production de tels polypeptides de fusion, tels que des acides nucléiques, et de telles bactéries recombinantes ou souches de Listeria. La présente invention concerne également des compositions immunogènes, des compositions pharmaceutiques, et des vaccins comprenant de tels polypeptides de fusion, de tels acides nucléiques, ou de telles bactéries recombinantes ou souches de Listeria. L'invention porte également sur des procédés d'induction d'une réponse immune anti-WT1 chez un sujet, sur des procédés d'induction d'une réponse immune anti-tumeur exprimant la WT1 ou anti-cancer exprimant la WT1 chez un sujet, des procédés de traitement d'une tumeur ou d'un cancer exprimant la WT1 ou associé(e) à la WT1 chez un sujet, des procédés de prévention d'une tumeur ou d'un cancer exprimant la WT1 ou associé(e) à la WT1 chez un sujet et des procédés de protection d'un sujet contre une tumeur ou un cancer exprimant la WT1 ou associé(e) à la WT1 à l'aide de tels polypeptides de fusion recombinants, de tels acides nucléiques, de telles souches recombinantes de bactéries ou de souches de Listeria, de compositions immunogènes, de compositions pharmaceutiques ou des vaccins.
