The ghrelin receptor (GHS-R1a) is a potential target for alcohol use disorders (AUD). PF-5190457 is the first inverse agonist of GHS-R1a to progress to clinical development with potential to treat AUD. We present a population pharmacokinetic (popPK) model for PF-5190457 in non-heavy (ALC=0) and heavy alcohol drinkers (ALC=1); and to identify relevant factors that can influence its PK. Plasma concentration-time data from non-heavy (n=35) and heavy drinkers (n=12) were pooled for the popPK model development. The influence of various covariates, including alcohol consumption status (ALC) were evaluated. The accuracy, precision and robustness of the model were also evaluated using bootstrapping and visual predictive checks. A two-compartment model best described the PK of PF-5190457. The apparent volume of distribution (V2/F) = 44.5 L, apparent clearance (CL/F) = 72.0 L/hr, apparent peripheral volume of distribution (V3/F) = 271 L, apparent distributional clearance (Q/F) = 28.7 L/hr, and first order absorption rate constant (ka) = 0.27 hr−1, were accurate and precise. The V2/F was 3.8-fold higher (169 L) in heavy drinkers, and correlated with a lower Cmax in heavy drinkers compared to non-heavy drinkers at the same dose; and a corresponding reduced incidence of somnolence in heavy drinkers at doses > 50 mg. This work provides an accurate, precise, and robust two compartment model that describes the PK of PF-5190457 and suggests a possible link of PF-5190457 pharmacokinetics with somnolence.
