SEQUENCE LISTING
The instant application contains a Sequence Listing which has been submitted
electronically in ASCII format and is hereby incorporated by reference in its 10 entirety. Said ASCII copy, created on March 7, 2014, is named 204257-0016-WO-

The การประดิษฐ์นี้ relates to a polyethylene glycol (PEG) modified canine
leptin polypeptide and related compositions and methods useful in treating companion 15 animal obesity and other leptin-related disorders.
Leptin is a neurohormone that acts in the hypothalamus to regulate energy balance and food intake. Much has been written about the problems associated with leptin and its receptor for humans (US2012/0149,636), but companion animals also suffer from leptin-
related disorders. Of particular note are companion animals, such as canines, which
20 experience leptin-disorders, such as obesity. While administering exogenous leptin as a
therapy is known in humans, it is hampered by several problems, not the least of which is the failure to provide long lasting effect. Thus, efforts to find better alternatives are
ongoing and these efforts รวมถึง finding safer, longer lasting, and more potent
compounds for humans as well as companion animals.
25 The การประดิษฐ์นี้ provides a compound comprising a polypeptide of SEQ ID
NO: I and a polyethylene glycol (PEG) moiety, โดยที่ the PEG moiety is covalently
attached to a para-acetyl-phenylalanine (pAF) residue of the polypeptide of SEQ ID NO:l.
The การประดิษฐ์นี้ also provides a method of treating obesity in companion animals comprising administering to an animal in need thereof an effective amount of a compound according to the การประดิษฐ์นี้.
The การประดิษฐ์นี้ also provides a method of preventing obesity in companion 5 animals comprising administering to an animal in need thereof an effective amount of a
compound according to the การประดิษฐ์นี้.
The การประดิษฐ์นี้ also provides a compound according to the การประดิษฐ์นี้ for use in therapy.
The การประดิษฐ์นี้ also provides a compound according to the present 10 การประดิษฐ์ for use in the treatment of obesity.
The การประดิษฐ์นี้ also provides a compound according to the การประดิษฐ์นี้ for use in the perevention of obesity.
The การประดิษฐ์นี้ also provides a composition comprising the compound according to the การประดิษฐ์นี้ and one or more carriers, diluents or excipients.
