Bevirimat (3-O-(3',3'-dimethylsuccinyl) betulinic acid or MPC-4326 or PA-457) potently inhibits replication of both WT and drug-resistant HIV-1 isolates and demonstrate that the compound acts by disrupting a late step in Gag processing involving conversion of the capsid precursor (p25) to mature capsid protein (p24). Bevirimat inhibits replication of both wild-type and drug-resistant HIV-1 isolates in vitro, achieving similar 50% inhibitory concentration values with both categories. Serial drug passage studies have identified six single amino acid substitutions that independently confer bevirimat resistance. These resistance mutations occur at or near the CA-SP1 cleavage site, which is not a known target for resistance to other antiretroviral drugs. Bevirimat has been in phase 2 trial for the treatment of HIV infections. Bevirimat has demonstrated a consistent pharmacokinetic profile in healthy volunteers and HIV-infected patients. The demonstration of an antiviral effect following a single oral dose of bevirimat validates maturation inhibition as a potential target for antiretroviral therapeutics in humans.

Sample Use Guides

In Vivo Use Guide

Four cohorts of six HIV-infected adults, with CD4 counts of >200 and plasma viral loads of 5,000 to 250,000 transcripts/ml and not currently receiving antiretroviral therapy, were randomized to receive a single oral dose of placebo, 75, 150, or 250 mg of bevirimat. The study was a 10-day, randomised, double-blind, placebo-controlled, dose escalation study. A total of 48 healthy male volunteers, aged 19-54 years, took part in the study. Treatment was administered for 10 days in six escalating dose cohorts (n = 8 in each cohort; 6 bevirimat, 2 placebo). The doses of bevirimat given in each successive cohort were 25 mg, 50 mg, 75 mg (with 150 mg loading dose), 100 mg, 150 mg and 200mg. Safety follow-up was performed 28 days after the first dose.

Route of Administration: Oral

In Vitro Use Guide

Bevirimat (PA-457) was shown to be a potent in vitro inhibitor of HIV-1 replication. In assays using patient-derived WT virus isolates, PA-457 exhibited a mean IC50 of 10.3 nM.
