Abstract: The invention provides methods of immunotherapy of Alzheimer's and similar diseases in which the regime administered is monitored by measuring levels of tau.

Abstract: The invention provides improved agents and methods for treatment of diseases associated with beta amyloid (A?). Preferred agents include antibodies, e.g., humanized antibodies specific for A?.

Abstract: The invention provides compositions and methods for treatment of amyloidogenic diseases. Such methods entail administering an agent that induces a beneficial immune response against an amyloid deposit in the patient. The methods are particularly useful for prophylactic and therapeutic treatment of Alzheimer's disease. In such methods, a suitable agent is A? peptide, active fragments thereof or an antibody thereto.

Abstract: The invention provides preferred dosage ranges, maximum concentrations, average concentrations and monitoring regimes for use in treatment of Alzheimer's disease using antibodies to A?. The invention also provides monitoring regimes that as can assess changes in symptoms or signs of the patient following treatment.

Abstract: The present application provides methods of purifying A? binding proteins having a Fc region, for example, anti-A? antibodies or antibody fusions, by adsorbing the A? binding protein to a Fc binding agent, such as, for example, Protein A or Protein G, followed by a wash with a divalent cation salt buffer to remove impurities and subsequent recovery of the adsorbed A? binding protein. The present application also features methods of eluting the purified A? binding protein as well as the incorporation of the methods within a purification train. Kits comprising components for carrying out the methods and instructions for use are also provided.

Abstract: The present invention provides methods of monitoring A?-directed immunotherapy. The methods involve administering a PET ligand that binds to amyloid deposits and detecting the PET ligand in the brain to provide an indication of the level and/or distribution of amyloid deposits. Surprisingly, the data in the present application show that a statistically significant reduction in amyloid deposits occurs early and consistently among patients following initiation of treatment before statistically significant effects of most if not all other markers are detectable. In consequence, the present methods allow early detection of whether a patient is responding to the A?-directed immunotherapy and if necessary adjustment of the immunotherapy regime.

Abstract: The invention provides improved agents and methods for treatment of diseases associated with amyloid deposits of A? in the brain of a patient. Such methods entail administering agents that induce a beneficial immunogenic response against the amyloid deposit. The methods are useful for prophylactic and therapeutic treatment of Alzheimer's disease. Preferred agents including N-terminal fragments of A? and antibodies binding to the same.

Abstract: The application provides novel neuroactive fragments of human amyloid precursor protein (APP). The fragments include sequence from the A? region of APP but also extend upstream. The fragments are soluble in aqueous solution most bands are about 10 kDa and above and do not correspond with the expected molecular weight of a dimer or trimer. The fragments and subfragments thereof can be used as immunogens in methods of immunotherapy to treat Alzheimer's and other amyloidogenic diseases characterized by deposits of A? in the brain. Antibodies to the part of the fragment upstream from APP or the interface between A? and the upstream sequence can also be used in such therapeutic method. The fragments are also useful as markers, which can be detected for diagnosis or prognosis of disease or for screening agents.

Abstract: The present invention provides formulations for maintaining the stability of A? binding polypeptides, for example, A? antibodies. Exemplary formulations include a tonicity agent such as mannitol and a buffering agent or amino acid such as histidine. Other exemplary formulations include an antioxidant in a sufficient amount as to inhibit by-product formation, for example, the formation of high molecular weight polypeptide aggregates, low molecular weight polypeptide degradation fragments, and mixtures thereof. The formulations of the invention optionally comprise a tonicity agent, such as mannitol, and a buffering agent or amino acid such as histidine. The formulations are suitable for several different routes of administration.

Abstract: The invention provides improved agents and methods for treatment of cerebral amyloid angiopathy (CAA) and methods to effect prophylaxis of CAA. The methods can treat CAA concurrently with Alzheimer's disease or separately. The methods can effect prophylaxis of CAA concurrently with Alzheimer's disease or separately. The methods involve administering antibody that is specific for the N-terminus of A? or an agent that can induce such an antibody.

Abstract: The present invention is directed to methods of producing conjugates of A? peptide immunogens with protein/polypeptide carrier molecules, which are useful as immunogens, wherein peptide immunogens are conjugated to protein carriers via activated functional groups on amino acid residues of the carrier or of the optionally attached linker molecule, and wherein any unconjugated reactive functional groups on amino acid residues are inactivated via capping, thus retaining the immunological functionality of the carrier molecule, but reducing the propensity for undesirable reactions that could render the conjugate less safe or effective. Furthermore, the invention also relates to such immunogenic products and immunogenic compositions containing such immunogenic products made by such methods.
