Methods of treating retroviral infections and related dosage regimes
View Patent ↗The present invention relates to compounds and methods for treating retroviral infections and/or Hepatitis B viral infections. Some compounds of the invention are described by Formula I: or a stereoisomer, a diastereomer, an enantiomer or racemate thereof.
1. A method of treating a retroviral infection in a primate subject, comprising administering to the subject a therapeutically acceptable amount of a compound of the structure:
wherein M + is K + , Na + , Li + , Ca 2+ , Mg 2+ , or [NR 1 R 2 R 3 R 4 ] + , wherein R 1 , R 2 , R 3 , and R 4 are each independently hydrogen or C 1-5 alkyl;
wherein the compound is administered to the subject daily or weekly in an amount of about 25 mg to about 400 mg, wherein the subject has an NRTI resistant HIV infection.
2. The method of claim 1 , wherein said subject is also infected with HBV.
3. The method of claim 1 , wherein the compound is administered to the subject daily.
4. The method of claim 1 , wherein the compound is administered to the subject weekly.
5. The method of claim 1 , wherein the compound is administered to the subject in an amount of about 25 mg.
6. The method of claim 1 , wherein the compound is administered to the subject in an amount of about 50 mg.
7. The method of claim 1 , wherein the compound is administered to the subject in an amount of about 100 mg.
8. The method of claim 1 , wherein the compound is administered to the subject in an amount of about 200 mg.
9. The method of claim 1 , wherein the compound is administered to the subject in an amount of about 400 mg.
10. The method of claim 1 , further comprising concurrently administering to the subject one or more additional antiviral agents with the compound.
11. The method of claim 10 , wherein the one or more additional antiviral agents is selected from the group consisting of HIV-protease inhibitors, nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, integrase inhibitors, entry inhibitors, fusion inhibitors, maturation inhibitors, and combinations thereof.
12. The method of claim 10 , wherein the one or more additional antiviral agents is selected from the group consisting of lamivudine, abacavir, zidovudine, stavudine, zalcitabine, didanosine, emtricitabine, tenofovir, delavirdine, efavirenz, etravirine, nevirapine, amprenavir, atazanavir, darunavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir, tipranavir, maraviroc, enfuvirtide, raltegravir, and combinations thereof.
13. The method of claim 10 , wherein the one or more additional antiviral agents is selected from the group consisting of raltegravir, ribavirin, indinavir, retrovir, and combinations thereof.
14. The method of claim 1 , wherein the NRTI-resistant HIV has a genotype selected from the group consisting of 41L/67N/70R/215F/219E, 41L/67N/210W/215Y/184V, 41L/67N/210W/215Y, 75I/77L/116Y/151M/184V, 41L/210W/215Y/184V/69SSS, and 65R/184V.
