  • Patent number: 11045533
    Abstract: The invention relates to humanized antibodies that bind to an epitope at the N-terminus of pyroglutamated amyloid beta (A? N3pE) peptide and to preventive and therapeutic treatment of diseases and conditions that are related to accumulation and deposition of amyloid peptides, such as amyloidosis, a group of disorders and abnormalities associated with pyroglutamated amyloid peptide, like Alzheimer's disease, Down's syndrome, cerebral amyloid angiopathy and other related aspects. More specifically, it pertains to the use of humanized monoclonal antibodies to bind pyroglutamated amyloid beta peptide in plasma, brain, and cerebrospinal fluid to prevent accumulation or to reverse deposition of A? N3pE within the brain and in various tissues in the periphery, and to alleviate amyloidosis. The present invention further pertains to diagnostic assays for the diagnosis of amyloidosis using the humanized antibodies of the invention.

  • Publication number: 20200264197
    Abstract: The present invention can be included in the field of medicine. Specifically, the present invention provides antibodies and antigen-binding fragments thereof which can bind isoAsp7 amyloid ? (A?) and a pharmaceutical composition comprising the antibodies or antigen-binding fragments thereof. IsoAsp7 A? can be found in plaques of Alzheimer's patients and is thus a suitable target for the treatment and/or prevention of A?-related diseases such as Alzheimer's disease. Thus, the antibodies, antigen-binding fragments thereof and the pharmaceutical composition comprising either can be used to treat and/or prevent neurodegenerative diseases. Further, the present invention provides hybridoma cell lines, the use of the antibodies or antigen-binding fragments thereof for the diagnosis and/or prognosis of a neurodegenerative disease and a method for detecting isoAsp7 A? in an isolated sample.
