This invention relates to novel compositions comprising analogs of naturally occurring polypeptides, wherein the analog comprises an α-amino acid and at least one β-amino acid. Administration of the compositions may be used for effecting treatment or prevention of a plurality of disease states caused by dysfunctional biochemical or biological pathways. The compositions and methods of this invention are particularly useful to identify novel therapeutic modulators of in-vivo receptor activity with extended half-lives and relevant bioactivity as compared to the naturally translated polypeptides upon which the analogs are derived.

The present invention relates to compositions of peptide and polypeptide analogs that are resistant to proteolysis, pharmaceutical uses thereof, and methods of preparation thereof.

The invention relates to biotechnology. The exenatide analogue with the formula H-His-Gly-Glu-Gly-Thr-Phe-Thr-Ser-As-Leu-Ser-Lys-Gln-Glu-Glu-Glu-Glu-Ala-Val-Arg-Leu-Phe-Ile-Glu-Trp-Leu-Lys-Asn-Gly-Gly-Pro-Ser-Ser-Gly-Ala- Pro-Pro-Pro-Ser-D-Arg-D-Arg-D-Arg-D-Arg-D-Arg-D-Arg-D-Arg-D-Arg-Gly-OH is presented. The invention allows treating and taking preventive measures against diabetes mellitus as well as treating and taking preventive measures against type 2 diabetes mellitus complications, such as diabetic neuropathy, muscular dystrophy and endotheliopathy.

Provided is an incretin, or analogue thereof, an incretin receptor agonist, an incretin enhancer, or any combination thereof, for use in a method of reducing elevated intracranial pressure (ICP) in a subject. Methods of reducing elevated ICP in a subject may comprise administering an incretin, or analogue thereof, an incretin receptor agonist, an incretin enhancer, or any combination thereof to the subject. The elevated ICP may be associated with idiopathic intracranial hypertension (IIH), secondary pseudotumour cerebri, hydrocephalus, normal pressure hydrocephalus, raised intracranial pressure secondary to a brain tumour, meningitis, brain trauma, brain injury, and venous sinus thrombosis.

The invention relates to composition comprising a pharmaceutically effective amount of one or more functional vasoactive intestinal peptide (VIP) fragments, and the use of those compositions in the treatment of fibrosis, hypertension and other disorders.

The present application provides methods and compositions for AAV-mediated delivery of PYY and Glucagon-like Peptide 1 or an analog thereof (e.g., Exendin-4) to a subject (e.g., the saliva of a subject). In some embodiments, compositions and methods for topical delivery of Ex-4 and PYY peptides also are provided. Methods and compositions are useful to promote weight loss and/or altered lipid taste sensitivity, as well as for the treatment of diabetes.

The present invention relates to dual GLP-1/glucagon receptor agonists or optionally trigonal GLP-1/glucagon/GIP receptor agonists and their medical use, for example in the treatment of disorders of the metabolic syndrome, including diabetes and obesity, as well as for reduction of excess food intake.

The present invention relates to neutralizing antibodies of the human pituitary adenylate cyclase activating polypeptide type I receptor (PAC1) and pharmaceutical compositions comprising such antibodies. Methods of treating or preventing headache conditions, such as migraine and cluster headache, using the neutralizing antibodies are also described.

The invention relates to a gene transfer-based method to protect a subject from diabetes or obesity. The method comprises administering to a salivary gland of the subject an AAV virion comprising an AAV vector that encodes an exendin-4 protein. Also provided are exendin-4 proteins and nucleic acid molecules that encode such exendin-4 proteins. Also provided are AAV vectors and AAV virions that encode an exendin-4 protein. One embodiment is an exendin-4 protein that is a fusion protein comprising an NGF secretory segment joined to the amino terminus of an exendin-4 protein domain.

This invention relates to methods of screening for anti-PACAP antibodies, or anti-PACAP receptor antibodies, and antigen binding fragments thereof, for potential use in treating or preventing PACAP-associated photophobia or light aversion, and therapeutic compositions containing and methods of using anti-PACAP antibodies, or anti-PACAP receptor antibodies, and antigen binding fragments thereof.
