Description

Aplaviroc (GW873140) is a small-molecule noncompetitive allosteric CCR5 antagonist or HIV entry inhibitor (EI) that binds specifically to human CCR5 and exhibits potent anti-HIV activity in vitro in the nanomolar or subnanomolar range. Aplaviroc has exhibited potent in vivo antiviral activity (1.66 log decrease in viral load at nadir) following 10 days of monotherapy. In vitro studies of antiviral activity demonstrate that aplaviroc is active against HIV isolates from a variety of clades as well as those resistant to current HIV therapies targeting RT, PR, and gp41. However, GlaxoSmithKline has decided to terminate Phase III trials of aplaviroc after encountering additional cases of liver damage in patients taking the drug.

Sample Use Guides

In Vivo Use Guide
HIV-infected male and female subjects (age, 22-60 years; weight, 50-97 kg) were randomized to receive placebo or aplaviroc doses of 200 mg once daily, 200 mg twice daily, 400 mg once daily, or 600 mg twice daily for 10 days.
Route of Administration: Oral
In Vitro Use Guide
R5-tropic HIV replication in PBMCs was inhibited by aplaviroc at an IC50 = 0.28 nM; this equates to a CCR5 RO of ~70%. Conversely, 50% CCR5 RO was achieved at 0.152 nM aplaviroc where ~36% inhibition of HIV replication was observed.
