title: Apricitabine--a novel nucleoside reverse transcriptase inhibitor for the treatment of HIV infection that is refractory to existing drugs.
abstract: BACKGROUND
  Apricitabine (ATC) is a nucleoside reverse transcriptase inhibitor (NRTI) being developed for the treatment of HIV. ATC has promising antiviral activity, including against HIV-1 containing reverse transcriptase mutations that confer resistance to other NRTIs.
  
  
  OBJECTIVE
  This paper describes the development of ATC, including its in vitro activity, pharmacokinetics and clinical efficacy and safety.
  
  
  METHODS
  The current literature on ATC was reviewed.
  
  
  CONCLUSIONS
  ATC is a novel deoxycytidine NRTI with good antiviral activity, both in vitro and in treatment-naïve and treatment-experienced HIV-1-infected patients, including those with resistance to other NRTIs. This activity is accompanied by a favourable safety profile and a low propensity to select for resistance. ATC may have a place in the treatment of patients who have failed previous treatment regimens due to the development of NRTI resistance as a replacement for existing drugs.
