PCSK9 VACCINE Russian patent published in 2015 - IPC A61K38/08 A61K38/10 A61P9/00 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to immunology and biotechnology. Presented is an immunogen for inducing an immune response to the PCSK9 protein, containing the PCSK9 antigen peptide specified in a group consisting of the disclosed SEQ ID NO: 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 314, 318 and 319, containing the amino acid sequence TRFHRQ, and SEQ ID NO: 182, 183, 184, 185, 186, 187, 188, 317, 401, 402 and 403, containing the amino acid sequence SIPWNLE, wherein the above PCSK9 peptide is conjugated with an immunogenic carrier specified in CRM197 or a Qbeta viral-like particle (VLP). Described is a composition for inducing the immune response to the PCSK9 protein containing at least two immunogens in immunologically effective amounts, wherein the first immunogen represents the above immunogen. Disclosed is a composition for inducing the immune response to the PCSK9 protein containing at least two immunogens in the immunologically effective amounts, wherein the first immunogen is specified in a group of immunogens containing the amino acid sequence SIPWNLE, and wherein the second immunogen is specified in a group of immunogens containing the amino acid sequence TRFHRQ; and wherein the composition can additionally contain at least one adjuvant. What is also presented is a pharmaceutical composition for preventing, treating or relieving PCSK9-related disorders containing: the above immunogen in a therapeutically effective amount, or one of the above compositions, and a pharmaceutically acceptable excipient.

EFFECT: invention enables preparing the effective vaccine for the disorders related to a reaction of the PCSK9 protein and its LDLR receptor.
