Objective.Nevirapine is metabolized by cytochrome P450 (CYP) 2B6 and CYP3A4. We characterized relationships between clinical parameters, human genetics, pharmacokinetics, and human immunodeficiency virus type 1 (HIV-1) drug resistance mutations in pregnant women following single-dose intrapartum nevirapine.Methods.In AIDS Clinical Trials Group study A5207, women received nevirapine at onset of labor and were randomly assigned to receive lamivudine/zidovudine, emtricitabine/tenofovir, or lopinavir/ritonavir for 7 or 21 days. Plasma nevirapine level was quantified on postpartum day 1 and on weeks 1, 3, and 5. We assayed 214 polymorphisms inCYP2B6and other genes and evaluated associations with pharmacokinetic parameters, including elimination constant, time to protein-adjusted 50% inhibitory concentration (IC50), and week 5 nevirapine level below the quantification limit.Results.Among 301 women with evaluable pharmacokinetic and genotype data, lower body mass index and random assignment to receive lopinavir/ritonavir were associated with more rapid nevirapine elimination. Among those of African ancestry, longer time to IC50was associated withCYP2B6983T→C (P= .004) but not withCYP2B6516G→T (P= .8). Among Indians, slower nevirapine elimination was associated withCYP2B6516G→T (P= .04). Emergent resistance was infrequent and not associated with pharmacokinetics orCYP2B6genotype.Conclusions.The effects on plasma drug exposure following single-dose nevirapine may be greater forCYP2B6983T→C than for 516G→T and are less pronounced than at steady state.
