The model at-a-glance

 Absorption Model
  • First-Order

 Volume of Distribution Details
  • Full PBPK (Method 2)

Note: Kp scalar and Kp adipose used

 Route of Elimination

CYP3A4 (40%); non-specific hepatic metabolism (60%)

 Perpetrator DDI
  • CYP2D6 Inhibitor

 Validation

  • Two clinical studies describing single dose exposure and two describing multiple dose exposure of lumefantrine were used to verify the PBPK model.
    • The single dose exposures were within 2-fold of observed for both studies.
    • The multiple dose exposures were within 1.25-fold of observed for both studies.
  • Clinical DDI studies with rifampicin and efavirenz in healthy volunteers where lumefantrine was the victim of CYP3A4-mediated DDIs were over-predicted (>2-fold) using the PBPK model.
  • An alternative clinical efavirenz DDI study in HIV patients and a clinical DDI with ritonavir in healthy volunteers were well predicted (within 1.25-fold of observed). As the effect of CYP3A4 inhibition was independently verified and there appeared to be variability in the extent of induction on lumefantrine PK, the fmCYP3A4 of 40% was considered verified.

 Limitations
  • Plasma concentrations of lumefantrine following a single dose are less accurately predicted than those following multiple dose administration. As the Day 7 plasma concentrations following repeat administration of lumefantrine, are more critical (linked to cure rates) than after the first dose, this was deemed acceptable.
  • The model can be used to prospectively predict CYP2D6-mediated DDIs but in the absence of verification of CYP2D6 inhibition, this should be accompanied by appropriate sensitivity analysis.​

 Updates in V19
  • Updates in vitro data based on new information
    • B:P ratio 0.6 -> 0.55
    • CYP2D6 Ki (µM) 2.2 -> 1.8
