  • Publication number: 20180079825
    Abstract: The invention provides a method for treating a medical condition, disease, or disorder mediated by a misfolded form of superoxide dismutase (SOD) in a subject in need of treatment. The method optionally comprises administering to the subject a composition comprising a pharmaceutically acceptable vehicle and an agent selected from (1) an exogenous antibody or fragment thereof that binds selectively to the misfolded form of SOD, and/or (2) an immunogen that elicits production of an endogenous antibody that binds selectively to the misfolded form of SOD, and/or (3) a nucleic acid sequence encoding (1) or (2). In certain embodiments, the invention provides methods of treating diseases such as Alzheimer's Disease, Parkinson's Disease or amyotrophic lateral sclerosis using amyotrophic disease-specific epitopes, and compositions including these epitopes. The invention also provides antibodies that bind to monomeric or misfolded SOD1, and not on the molecular surface of native homodimeric SOD1.

  • Patent number: 9879080
    Abstract: The invention provides antibodies that specifically bind to transthyretin (TTR). The antibodies can be used for treating or effecting prophylaxis of diseases or disorders associated with TTR accumulation or accumulation of TTR deposits (e.g., TTR amyloidosis). The antibodies can also be used for diagnosing TTR amyloidosis and inhibiting or reducing aggregation of TTR, among other applications.
