Dolutegravir is an HIV integrase inhibitor with a high genetic barrier to resistance and is active against raltegravir- and/or elvitegravir-resistant strains. The clinical development of dolutegravir for HIV infection rescue therapy is based on 3 clinical trials. In the SAILING trial, dolutegravir (5 mg once daily) in combination with 2 other antiretroviral agents was well tolerated and showed greater virological effect than raltegravir (400 mg twice daily) in the treatment of integrase inhibitor-naïve adults with virological failure infected with HIV strains with at least two-class drug resistance. The VIKING studies were designed to evaluate the efficacy of dolutegravir as rescue therapy in treatment-experienced patients infected with HIV strains with resistance mutations to raltegravir and/or elvitegravir. VIKING-1-2 was a dose-ranging phase IIb trial. VIKING-3 was a phase III trial in which dolutegravir (50 mg twice daily) formed part of an optimized regimen and proved safe and effective in this difficult-to-treat group of patients. Dolutegravir is the integrase inhibitor of choice for rescue therapy in multiresistant HIV infection, both in integrase inhibitor-naïve patients and in those previously treated with raltegravir or elvitegravir.
