Abstract

Provided are methods, uses, pharmaceutical regimens, pharmaceutical compositions, and kits comprising modulators of TLR7, including those of Formula II:

and pharmaceutically acceptable salts thereof, useful in treating HIV infections.

First claim

We claim:

1 . A method of treating an HIV infection in a human, the method comprising administering to a human in need thereof a pharmaceutically effective amount of a TLR7 modulating compound, or a pharmaceutically acceptable salt thereof.

2 . A method of treating an HIV infection in a human, the method comprising:
a) administering to a human in need thereof a pharmaceutically effective amount of a combination antiretroviral therapy regimen sufficient to lower the level of HIV detected in the human's blood or plasma from a first level to a second level, the second level comprising a lower concentration of HIV in the human's blood or plasma than the concentration of HIV in the human's blood or plasma in the first level; and b) administering to the human a pharmaceutically effective amount of a TLR7 modulating compound, or a pharmaceutically acceptable salt thereof.

3 . The method of claim 2 wherein the first level of HIV in the human's plasma is below 50 copies of HIV RNA/ml.

4 . The method of claim 2 wherein the second level of HIV in the human's plasma is below 30 copies of HIV RNA/ml.

5 . The method of claim 2 wherein the first level of HIV in the human's plasma is below 10 copies of HIV RNA/ml.

6 . The method of claim 2 wherein the first level of HIV in the human's plasma is below 1 copy of HIV RNA/ml.

7 . The method of claim 2 further comprising the step of administering to the human a pharmaceutically effective amount of an HIV antibody.

8 . The method of claim 2 further comprising the step of administering to the human in need thereof a pharmaceutically effective amount of an HIV vaccine.

9 . The method of claim 2 wherein the administration of the pharmaceutically effective amount of the TLR7 modulating compound induces transient HIV-1 viremia in the human.

10 . The method of claim 2 wherein the HIV infection is eliminated from the human.

11 . The method of claim 2 , wherein the TLR7 modulating compound is a compound of Formula II, or a pharmaceutically acceptable salt thereof:
