Materials and methods for treating bacterial infections using C-1 gentamicin
Various aspects relate to the use of C-1 gentamicin as an antibiotic effective for the treatment of a bacterial infection, a genetic disorder, or cancer in a subject.
1. A method of treating a condition in a subject comprising administering a composition comprising C-1 gentamicin or a pharmaceutically acceptable acid addition salt thereof, wherein the composition is substantially free of C-1a gentamicin, C-2 gentamicin and C-2a gentamicin, and the condition is selected from the group consisting of a bacterial infection, a monogenic genetic disease and cancer.
2. The method of claim 1 , wherein the condition is a monogenic genetic disease that is cystic fibrosis, Hurler Syndrome, Schele syndrome, Duchenne muscular dystrophy, Becker muscular dystrophy, nephrogenic diabetes insipidus, hemophilia, dystrophic epidermolysis bullosa, or Kabuki syndrome.
3. The method of claim 1 , wherein the condition is cancer and wherein the cancer cells comprise a premature stop codon in a gene encoding a cell regulatory protein.
4. The method of claim 1 , wherein the composition has a ratio of C-1a gentamicin to C-1 gentamicin of less than 1:10 (w/w).
5. The method of claim 1 , wherein the composition has a ratio of C-2a gentamicin to C-1 gentamicin of less than 1:10 (w/w).
6. The method of claim 1 , wherein the composition has a ratio of C-1 gentamicin to total gentamicin of greater than 9:10 (w/w).
7. The method of claim 1 , wherein the composition is a liquid, and the composition comprises C-1 gentamicin at a concentration between about 1 mg/mL and about 115 mg/mL.
8. The method of claim 1 , wherein the composition is a liquid, and the composition comprises less than 1000 ppm C-1a gentamicin.
9. The method of claim 1 , wherein the composition is a liquid, and the composition comprises less than 1000 ppm C-2a gentamicin.
10. The method of claim 1 , wherein the composition is a liquid, and the composition is for intravenous or intramuscular injection.
11. The method of claim 10 , wherein the composition comprises greater than about 1 mg/kg total gentamicin.
12. The method of claim 1 , wherein the composition further comprises at least one additional antibiotic.
13. The method of claim 1 , wherein the composition comprises C-1 gentamicin or a pharmaceutically acceptable acid addition salt thereof in a therapeutically effective amount.
14. The method of claim 1 , wherein the condition is a bacterial infection.
15. A composition comprising C-1 gentamicin or a pharmaceutically acceptable acid addition salt thereof, a preservative, and a chelating agent, wherein the composition is a liquid, and the composition is substantially free of C-1 a gentamicin, C-2 gentamicin and C-2a gentamicin.
16. The composition of claim 15 , wherein the composition comprises less than 1000 ppm C-1a gentamicin.
17. The composition of claim 15 , wherein the composition comprises less than 1000 ppm C-2a gentamicin.
