Coinfection with both HIV and HCV is not uncommon because of shared transmission modes. Globally, approximately 7 million people are thought to be coinfected with both HIV and HCV and, in the United States, about one-quarter to one-third of HIV-infected individuals are estimated to be coinfected with HCV [3].

Although combination antiretroviral therapy has extended the life expectancy of people with HIV, liver disease has become the leading cause of non-AIDSrelated deaths in this population, and HIV-infected people coinfected with HCV are at increased risk for serious, lifethreatening complications [3?]. Treatment for HCV infection has made remarkable progress in the last several years, from treatments with relatively low cure rates that typically included pegylated interferon alfa in combination with ribavirin, to all-oral, direct-acting antiviral regimens that produce sustained viral responses with cure rates exceeding 90 for many patient populations [5]. Dolutegravir (DTG, Tivicay? ViiV Healthcare, Research Triangle Park, NC) is an HIV-1 integrase strand transfer inhibitor approved by the Food and Drug Administration and the European Medicines Agency for the treatment of HIV-1 infection in a broad patient population [6, 7]. Daclatasvir (DCV, DaklinzaTM, Bristol-Myers Squibb, Princeton, NJ) is an inhibitor of the HCV nonstructural protein NS5A and has been approved by the European Medicines Agency for use in combination with other medicinal products across genotypes 1, 3, and 4 for the treatment of chronic HCV infection in adults and by the Food and Drug Administration for the treatment PubMed ID: of chronic HCV genotype 3 infection in adults [8, 9]. Because DTG and DCV may be concomitantly administered in subjects coinfected with HIV-1 and HCV, a drug interaction study between DTG and DCV was warranted to evaluate the pharmacokinetics (PK) of both drugs, as well as patient safety and drug tolerability when these drugs are coadministered.MethodsStudy design and sub.
