Abstract: Compounds, compositions, and methods of treatment and prevention of HIV infection are disclosed. The compounds are pyrrolo[2,3-b]pyridines and pyrrolo[2,3-b]pyrimidine JAK inhibitors. Combinations of these JAK inhibitors and additional antiretroviral compounds, such as NRTI, NNRTI, integrase inhibitors, entry inhibitors, protease inhibitors, and the like, are also disclosed. In one embodiment, the combinations include a combination of adenine, cytosine, thymidine, and guanine nucleoside antiviral agents, optionally in further combination with at least one additional antiviral agent that works via a different mechanism than a nucleoside analog. This combination has the potential to eliminate the presence of HIV in an infected patient.

Abstract: Compounds, compositions, and methods of treatment and prevention of HIV, including HIV-1 and HIV-2, Dengue, and Chikungunya infection are disclosed. The compounds are TREM-1 inhibitors. Combinations of these TREM-1 inhibitors and additional antiretroviral compounds, such as NRTI, NNRTI, integrase inhibitors, entry inhibitors, protease inhibitors, JAK inhibitors, macrophage depleting agents, and the like, are also disclosed. In one embodiment, the combinations include a combination of adenine, cytosine, thymidine, and guanine nucleoside antiviral agents, optionally in further combination with at least one additional antiviral agent that works via a different mechanism than a nucleoside analog. This combination has the potential to eliminate the presence of HIV, Dengue, or Chikungunya virus in an infected patient.

Abstract: Compounds, compositions, and methods of treatment and prevention of Hepacivirus, Pestivirus, Flavivirus or Alphavirus infection are disclosed. The compounds are pyrrolo[2,3-b]pyridines and pyrrolo[2,3-b]pyrimidine JAK inhibitors. Combinations of these JAK inhibitors and additional antiretroviral compounds, such as NRTI, NNRTI, integrase inhibitors, entry inhibitors, protease inhibitors, and the like, are also disclosed. In one embodiment, the combinations include a combination of adenine, cytosine, thymidine, and guanine nucleoside antiviral agents, optionally in further combination with at least one additional antiviral agent that works via a different mechanism than a nucleoside analog. This combination has the potential to eliminate the presence of Hepacivirus, Pestivirus, Flavivirus or Alphavirus in an infected patient.

Abstract: The present disclosure relates to solid dosage forms comprising anti-HCV compounds and methods of using such dosage forms to treat or prevent HCV infection. Direct-acting antiviral agents (DAAs) have a high cure rate, and favorable tolerability in persons infected with hepatitis C virus (HCV). However, shorter courses of therapy can improve adherence, affordability, and increase DAAs accessibility. The addition of an NS3 protease inhibitor to dual NS5A-NS5B (nucleoside) inhibitors enhances antiviral efficacy, and reduces treatment duration to 3 weeks (wks) in individuals with a rapid virologic response (RVR), defined as plasma HCV RNA<500, or <1,000, IU/mL by Day 2 of treatment.

Abstract: The present invention is directed to compounds, compositions and methods for preventing, treating or curing Hepatitis B (HBV) infection in human subjects or other animal hosts. The compounds are as also pharmaceutically acceptable, salts, prodrugs, and other derivatives thereof as pharmaceutical compositions and methods for treatment, prevention or eradication of HBV infection.
