Summary for Patent: 8,568,740

Title:	Compositions and methods of topical application and transdermal delivery of botulinum toxins with reduced non-toxin proteins
Abstract:	This invention relates to novel compositions of botulinum toxin that can be applied topically for various therapeutic, aesthetic and/or cosmetic purposes. The compositions may include botulinum toxin complexes, wherein the amounts of hemagglutinin, non-toxin non-hemagglutinin and/or exogenous albumin are selectively and independently reduced compared to conventional commercially available botulinum toxin. The compositions may further contain molecules that are not native to botulinum toxin and that bind non-covalently to the botulinum toxin complexes, thereby acting as skin-tropic \"adhesion molecules\" to improve the ability of the toxin complexes to adhere to and to penetrate the skin epithelium. The compositions have an improved safety profile compared to existing botulinum-containing compositions that are injected subcutaneously. Methods for the use of such compositions are also contemplated by this invention.
Inventor(s):	Waugh; Jacob M. (Mountain View, CA)
Assignee:	Revance Therapeutics, Inc. (Newark, CA)
Application Number:	11/560,555
Patent Claims:	1. A composition for transdermal delivery of botulinum toxin comprising: botulinum toxin; and a sialoprotein adhesion molecule; wherein the sialoprotein adhesion molecule forms a non-covalent complex with the botulinum toxin, and wherein the sialoprotein adhesion molecule is present in said composition in an amount from 0.1 ng to 1 mg per unit of botulinum toxin, inclusive. 2. The composition according to claim 1, wherein the composition further comprises an exogenous stabilizer. 3. The composition according to claim 1, further comprising hemagglutinin protein or non-toxin, non-hemagglutinin protein associated with the botulinum toxin and wherein said hemagglutinin proteins or non-toxin, non-hemagglutinin protein is in an amount less than the amount of hemagglutinin protein or non-toxin, non-hemagglutinin protein present in naturally occurring in-botulinum toxin complexes directly extracted from Clostridium botulinum. 4. The composition of according to claim 2, wherein the exogenous stabilizer is albumin. 5. The composition of claim 1, wherein the botulinum toxin is selected from the group consisting of a botulinum toxin derivative, a recombinant botulinum toxin, a modified botulinum toxin, botulinum toxin type A, botulinum toxin type B, botulinum toxin type C, botulinum toxin type D, botulinum toxin type E, botulinum toxin type F, and botulinum toxin type G. 6. The composition according to claim 1, wherein the botulinum toxin is present in a botulinum toxin complex. 7. The composition according to claim 1, wherein the botulinum toxin is present in a reduced botulinum toxin complex. 8. The composition according to claim 1, wherein the sialoprotein adhesion molecule is selected from the group consisting of bone sialoprotein I and bone sialoprotein II. 9. The composition according to claim 8, where the sialoprotein adhesion molecule is bone sialoprotein I. 10. The composition according to claim 8, wherein the sialoprotein adhesion molecule is bone sialoprotein II.
