ABSTRACT
The article reports on the separate clinical trials involving CCR5 antagonists, GlaxoSmithKline's aplaviroc, Pfizer's maraviroc and Schering-Plough's vicriviroc, in patients with AIDS. In healthy volunteers, the substances exhibited an efficacy to prevent the propagation of virus strains with all kinds of mutations. CCR5 seemed a promising target for co-receptor antagonists as a natural deletion in the CCR5 encoding region enables individuals to resist HIV infection or delay HIV disease progression. The clinical trials have failed to clarify the mechanisms of resistance development during treatment with CCR5 receptor antagonist.
