Aplaviroc (INN, codenamed AK602 and GSK-873140) is a CCR5 entry inhibitor that belongs to a class of 2,5-diketopiperazines[1] developed for the treatment of HIV infection.[2][3] It was developed by GlaxoSmithKline.

In October 2005, all studies of aplaviroc were discontinued due to liver toxicity concerns.[4][5] Some authors have claimed that evidence of poor efficacy may have contributed to termination of the drug's development;[6] the ASCENT study, one of the discontinued trials, showed aplaviroc to be under-effective in many patients even at high concentrations.[7]
