Aplaviroc (INN, codenamed AK602 and GSK-873140) is a CCR5 entry inhibitor developed for the treatment of HIV infection.[1][2] It was developed by GlaxoSmithKline.

In October 2005, all studies of aplaviroc were discontinued due to liver toxicity concerns.[3][4] Some authors have claimed that evidence of poor efficacy may have contributed to termination of the drug's development;[5] the ASCENT study, one of the discontinued trials, showed aplaviroc to be under-effective in many patients even at high concentrations.[6]
