Figure Lengend Snippet: Fig. 2. Simplified diagram for the semi-PBPK model of maribavir disposition in cynomolgus monkeys. Numbers in the graph denote physiologic and biologic pro- cesses: (1) transit of substance from stomach to duodenum; (2) transit within the small intestine; (3) transit within the colon and to feces; (4) absorption from the small intestine; (5) conversion of glucuronides to parent, which occurs in the last two compartments of the ileal lumen and throughout the colon; (6) absorption from the colon; (7) biliary excretion of parent; (8) glucuronidation of parent and secretion to duodenal lumen; (9) excretion of glucuronides in urine; (10) transport between the liver and central compartment; (11) transport between the central and peripheral compartments; (12) renal excretion of parent; and (13) all other pathways for parent. The two segments of the jejunum, four segments of the ileum, and five of the colon were not separately depicted in this diagram; the detailed diagram in MATLAB SimBiology is shown in Supplemental Fig. 1. MBV, maribavir (parent); MBV-Gluc, maribavir glucuronides; Met, other metabolites of maribavir.

Article Snippet: The model construction, parameter estimation, simulations, and sensitivity analyses were conducted with SimBiology version 5.7 hosted in MATLAB R2017b with Optimization Toolbox version 8.0 (The Mathworks Inc., Natick, MA).

Observed plasma concentration vs. time profiles of maribavir in cynomolgus monkey overlaid with fitted curves [BDC only (A)] or simulations [intact animals (B, C, D, and E)] in MATLAB SimBiology. (A) Observed data in individual BDC animals overlaid with fitted curve; (B) simulated data with a single intravenous administration in intact animals, using fm(Gluc) at 0.728 or 0.853 at both 5-mg/kg and 13-mg/kg doses, overlaid with individually observed data; (C) simulated data with a single p.o. administration in intact animals, using fm(Gluc) at 0.728 at 10-mg/kg dose, overlaid with individually observed data; (D) simulated data with repeated b.i.d. p.o. administration at 10, 30, or 100 mg/kg in intact male animals within the first 8 hours on day 2, using fm(Gluc) at 0.728, overlaid with individually observed data (Koszalka et al., 2002); (E) simulated data with repeated b.i.d. p.o. administrations at 10, 30, or 100 mg/kg in intact male animals within the first 8 hours on day 27, using fm(Gluc) at 0.728, overlaid with individually observed data (Koszalka et al., 2002).
