Monthly or Quarterly Injectable HIV Antiretrovirals Are Safe and Effective in Early Study

GSK744, an investigational integrase inhibitor, and TMC278 LA (a long-acting, injectable form of the NNRTI rilpivirine [Edurant]) both showed safety and efficacy when administered in once-monthly or once-quarterly doses, according to a study presented at IAS 2013. There were no drug-related serious adverse events and all adverse events were either mild or moderate.

The phase 1 study, conducted by GlaxoSmithKline and Janssen, assessed the safety, tolerability, and pharmacokinetics of GSK744 (when given intramuscularly or subcutaneously) in conjunction with TMC278 LA (injected intramuscularly). The researchers enrolled 47 HIV-uninfected individuals (17 female and 30 male) with a median age of 39.5. Thirty-five were white, 10 black, and two of another race.
