Budesonide_V22R1_UniversityOfManchester_20240502

The Budesonide compound file was evaluated in a Crohn’s Disease (CD) population (PMID: 37765205) and two workspaces are supplied to recover the pharmacokinetic profiles published by Ludin et al. in 2001 and Wilson et al., 2017. The Crohn’s disease population is based on the population presented in PMID: 36056298 (link). A third workspace recovers the clinical profile for Budesonide in a healthy volunteer population (Edsbäcker et al., 2004).

Metabolite of fesoterodine. Note/correction: 1. PKa 9.3 instead of 7.6 (in supplemental materials) 2. the intrinsic clearance (CLint) values of CYP3A4 and CYP2D6 should be 0.085 and 1.455 uL/min/pmol enzyme 3. note simulation with ketoconazole, ketoconazole cmp file modified with p-gp inhibition constant (Ki) of 0.015 uM (assumed)

The model at-a-glance

  Absorption Model

First-Order

  Volume of Distribution

Full PBPK (Method 2)

  Route of Elimination

Formed by CYP2C19, CYP3A4; unknown clearance mechanism

  Perpetrator DDI

  • CYP2D6 Inhibitor

  Validation

  • Proguanil and cycloguanil files were built using in vitro and clinical (Jeppersen et al., 1997) data
  • 5 clinical studies describing single and multiple dose exposure of cycloguanil were used to verify the PBPK model. 60% of studies were within 2-fold, of which 40% were within 1.5-fold.
  • A clinical DDI study where proguanil was the victim of a CYP2C19-mediated DDI was accurately recovered using the PBPK model.  

  Limitations

  • Prediction of cycloguanil exposure was complicated by not knowing the polymorphism classification of subjects in each study, hence the model performance was deemed acceptable using the criteria of being within 2-fold of observed.
  • Verification needed for perpetrator DDI assessment as literature data is unavailable at this time

  Updates in V19

  • Recalculated fm values using the corrected dose administered in Jeppesen et al., 1997
  • Previous version used paper calculation of total clearance which did not account for the weight of the salt in the 200 mg dose administered
  • Model converted from minimal to full PBPK distribution model
  • Updated in vitro data
  • Updated CYP2D6 IC50
