Provided is a long-acting PCSK9-specific binding protein and application thereof. Provided is an MV072 protein with unique complementarity-determining regions, i.e., a binding protein specifically binding to proprotein convertase subtilisin kexin type 9 (PCSK9). The protein can specifically bind to PCSK9, effectively inhibit the function of PCSK9 and reduce plasma LDL cholesterol level. Further provided is an application of the binding protein in treating diseases related to or influenced by the function of PCSK9.

The present invention relates to a vaccine capable to induce the formation of antibodies directed to PCSK9 in vivo.

The present disclosure provides improved genome editing compositions and methods for editing a PCSK9 gene. The disclosure further provides genome edited cells for the prevention, treatment, or amelioration of at least one symptom of hypercholesterolemia or a condition associated therewith.

This invention relates to methods for increasing the efficiency of siRNA administrations via pre-administration of an agent that lowers LDL receptor levels.

A vaccine construct comprising an antigenic PCSK9 peptide and an immunogenic carrier, and methods of using the same that are effective to lower blood cholesterol levels in a mammal and treat dyslipidemias and related disease states in a mammal without the frequency of administration required by passive immunity strategies.

An human antibody or antigen-binding fragment of a human antibody that specifically binds and inhibits human proprotein convertase subtilisin/kexin type 9 (hPCSK9) characterized by the ability to reduce serum LDL cholesterol by 40-80% over a 24, 60 or 90 day period relative to predose levels, with little or no reduction in serum HDL cholesterol and/or with little or no measurable effect on liver function, as determined by ALT and AST measurements.

Provided herein are multifunctional heteromer proteins. In specific embodiments is a heteromultimer that comprises: at least two monomeric proteins, wherein each monomeric protein comprises at least one cargo polypeptide, attached to a transporter polypeptide, such that said monomeric proteins associate to form the heteromultimer. These therapeutically novel molecules comprise monomers that function as scaffolds for the conjugation or fusion of therapeutic molecular entities resulting in the creation of bispecific or multivalent molecular species.

The present invention provides a vaccine containing a complex of a peptide consisting of the amino acid sequence of SEQ ID NO: 1 and an epitope of a disease-causing biological protein such as DPP4, IL-17A, IgE, S100A9 or PCSK9, which vaccine uses a less antigenic carrier protein and is capable of inducing antibody production to serve as an effective vaccine.

Provided herein are compositions for gene modification or editing and methods of using same to treat or prevent certain conditions. Specific compositions and methods capable of safely and effectively editing gene targets expressed in the liver to durably lower LDL-C thereby treating a leading cause of cardiovascular disease are disclosed.

Disclosed herein are siRNA duplexes, pharmaceutical compositions, and methods for suppressing the expression of proprotein convertase subtilisin/kexin type 9 serine protease (PCSK9).
