Abstract

Glycopeptide antibiotics, such as oritavancin, demonstrate significant activity against both a vegetative form of C. difficile and C. difficile spores. Methods for the treatment, prophylaxis and prevention of C. difficile infection and disease in animals, including humans, are described.

Claims (13)

1. A method of treating a C. difficile infection in a subject, consisting of administering a therapeutically effective amount of a glycopeptide antibiotic to a subject having a C. difficile infection, thereby treating a C. difficile infection in a subject, wherein the glycopeptide antibiotic is oritavancin, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, or a mixture thereof.

2. The method of claim 1 , wherein C. difficile is a vegetative form of C. difficile , a C. difficile spore or a mixture of both.

3. The method of claim 1 , wherein the glycopeptide antibiotic is in the form of a pharmaceutical composition comprising the glycopeptide antibiotic and a pharmaceutically acceptable carrier or diluent.

4. The method of claim 1 , wherein said treating inhibits outgrowth of a C. difficile spore, inhibits growth of a vegetative form of C. difficile or inhibits C. difficile sporulation.

5. The method of claim 1 , wherein the therapeutically effective amount of the glycopeptide antibiotic is between about 5 and 30 mg/kg body weight.

6. The method of claim 1 , wherein said administering is BID for four days.

7. A method of preventing a C. difficile infection in a subject, consisting of administering to a subject exposed to C. difficile bacteria an amount of a glycopeptide antibiotic sufficient to prevent C. difficile infection, thereby preventing a C. difficile infection in a subject, wherein the glycopeptide antibiotic is oritavancin, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, or a mixture thereof.

8. The method of claim 7 , wherein C. difficile is a vegetative form of C. difficile , a C. difficile spore or a mixture of both.

9. The method of claim 7 , wherein said administering is via intravenous administration or oral administration.

10. The method of claim 7 , wherein the glycopeptide antibiotic is in the form of a pharmaceutical composition comprising the glycopeptide antibiotic and a pharmaceutically acceptable carrier or diluent.

11. The method of claim 7 , wherein said preventing inhibits outgrowth of a C. difficile spore, inhibits growth of a vegetative form of C. difficile or inhibits C. difficile sporulation.

12. The method of claim 7 , wherein the amount of a glycopeptide antibiotic sufficient to prevent C. difficile infection is between about 5 and 30 mg/kg body weight.

13. The method of claim 7 , wherein said administering is BID for four days.
