Search the PBPK Model Repository

Quickly find freely available drug and population models in our PBPK model repository.

The models provided have been collated from published examples which authors have shared in our Published Model Collection or developed as part of various global health projects in our Global Health Collection. This search facility searches both model collections simultaneously.

Osimertinib_V14R1_AstraZeneca_20190717
Compound file from publication: Development, Verification, and Prediction of Osimertinib Drug-Drug Interactions Using PBPK Modeling Approach to Inform Drug Label. Pilla Reddy V, Walker M, Sharma P, Ballard P, Vishwanathan K (2018). CPT Pharmacometrics Systems Pharmacolology. doi: 10.1002/psp4.12289.
Entecavir_V15R1_USFDA_20170810
Entecavir compound file in healthy volunteers. Evaluation of the effect of renal impairment on PK of OAT substrates. NOTE: file has predicted Vss of 0.98 L/kg. Table 1 value is 0.9 L/kg. http://onlinelibrary.wiley.com/doi/10.1002/cpt.750/full
MefenamicAcid_Dapagliflozin_V15R1_Pfizer_20220726
Mefenamic acid and dapagliflozin/healthy volunteer. This workspace simulates the UGT mediated DDI after multiple dose administration of UGT inhibitor mefenamic acid. The workspace shows Dapaglifazin as substrate of UGTA9 and UGT2B7. Mefenamic Acid is used in the inhibitor position and Ki values against UGT1A9 and UGT2B7 are included in the workspace.

Brand Name(s) include: Malarone

Disease: Malaria

Drug Class: Antimalarials

Date Updated: March 2021

The model at-a-glance

  Absorption Model

  • First-Order

  Volume of Distribution

  • Full PBPK (Method 2)

Note: A Kp scalar (0.04) was used in the model

  Route of Elimination

  • No metabolism; a biliary CLint was input based on clinical data

  Perpetrator DDI

  • None

  Validation

  • Two clinical studies describing single and multiple dose exposure of atovaquone were used to verify the PBPK model. 100% of studies were within 1.5-fold.

  Limitations

  • There are some data to suggest atovaquone is an inhibitor of BCRP.  This is currently not included within the model.

  Updates in V19

  • Updated in vitro­ data
    • LogP: 5.8 -> 8.4
    • Caco-2 Papp 164 > 300 x 10-6 cm/s
    • Propranolol Papp 101 x 10-6 cm/s
  • Optimized ka and tlag
  • Converted from minimal PBPK model to full PBPK model
