The model at-a-glance

  Absorption Model

  • First-Order

  Volume of Distribution

  • Full PBPK (Method 3)
  • Note: Kp scalar used

  Route of Elimination

  • CYP1A2, CYP2B6, CYP2C8, CYP2D6 and CYP3A4

  Perpetrator DDI

  • CYP2D6 Inhibitor
  • P-gp Inhibitor

  Validation

  • Two clinical studies describing pyronaridine exposure were available for model verification.  100% of predicted Cmax were within 1.5-fold of those observed whereas 40% of AUC were predicted within 1.5-fold of observed. This can be explained as observed exposure at 9mg/kg dose was lower than at 6 mg/kg.  The model recovered the observed data at the 6 mg/kg dose but then over predicted that at the higher dose.

  Limitations

  • One challenge in the verification of the model is the diverse ethnicities of subjects in reported clinical data and how best to reflect this in simulations.  In the absence of virtual Korean populations within the Simulator, the Caucasian population was modified in terms of bodyweight.  In the absence of supporting information, no changes to enzyme abundance (pmol/mg) were made to the population, although changes to liver weight (as a function of body weight) and hence total CYP abundance were propagated into the model.

  Updates in V19

  • Switched to Method 3 to facilitate like for like comparisons for covid- 19     repurposing strategies

 

Cidofovir_V12R1_FDA_20150709

Table 1 of main text, further discussion in supplemental file. Clarification: the value of intrinsic CL for hepatic elimination (0.41) is for undefined human liver microsomes according to retrograde calculation, with a unit of uL/min/mg. The operating hepatic CLint is driven by S9, which has a value of 0.13, obtained from sensitivity analysis to match HLM value above. This clarification will be informed to the journal.

Lopinavir&Ritonavir_V13R2_USFDA_20190719

Compound files from publication: Physiologically Based Pharmacokinetic Modeling for Predicting the Effect of Intrinsic and Extrinsic Factors on Darunavir or Lopinavir Exposure Coadministered With Ritonavir Wagner, C., Zhao, P., Arya, V., Mullick, C., Struble, K. and Au, S (2017). https://doi.org/10.1002/jcph.936 /PMID#: 28569994 The compound file is the final model used for simulations in combination with ritonavir (submitted to repository referencing the same article). Correction: Ritonavir's pKa 2 should be 2.6, reported in Supp. Table 1 was 2.8 https://accp1.onlinelibrary.wiley.com/doi/full/10.1002/jcph.936
