Dolutegravir: An Integrase Strand Transfer Inhibitor for the Treatment of Human Immunodeficiency Virus 1 in Adults.

ABSTRACT: Objective: To review the efficacy, safety, pharmacokinetics, pharmacodynamics, administration, drug interactions, and cost of dolutegravir (Tivicay), a third in class integrase strand transfer inhibitor (INSTI), for the treatment of human immunodeficiency virus (HIV-1) in adults. Data Sources: MEDLINE, International Pharmaceutical Abstracts, ClinicalTrials.gov, and Google Scholar searches (January 2000 to May 2014) were conducted for articles published in English and limited to human subjects, using the key words antiretroviral drugs, HIV integrase strand transfer inhibitors, dolutegravir, DTG, and S/GSK1349572. Study Selection and Data Extraction: Following MEDLINE, International Pharmaceutical Abstracts, ClinicalTrials.gov, and Google Scholar searches, 6 clinical trials were identified and included in this review. Phase III/IV studies evaluating the safety and efficacy of dolutegravir in humans were selected and evaluated. Data Synthesis: In treatment naïve and experienced patients dolutegravir was noninferior to raltegravir at suppressing viral load when added to background therapy. Abacavir/lamivudine/dolutegravir was noninferior to efavirenz/emtricitabine/tenofovir disoproxil fumarate and darunavir/ritonavir plus background therapy at suppressing viral load. In patients with multiple-class antiretroviral resistance at baseline, dolutegravir decreased HIV RNA by 1.4 log10 copies/mL at day 8, 63% of patients had achieved virologic suppression at week 8, and retained potency in treatment-experienced INSTI-resistant patients up to week 48 or 96 of follow-up. Conclusion: Dolutegravir is a safe, effective, and well-tolerated treatment option for adults with HIV-1, even in the setting of resistance to other antiretrovirals.
