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.

Searching Tips!

You can use a suffix operator (*) as the placeholder for end of a term. The query must start with at least one alphanumeric character before the suffix operator. E.g., Rifam* will get you “Rifampicin” and “Rifampin”. For more advanced searching tips click here.

Hyperforin_V17R1_UniversityOfSydney_20190131

Model Files Publication

The submitted compound file describes the PBPK model for hyperforin (from St John's wort extract). The PBPK model implements first-order absorption model, full-PBPK (method 2) for its distribution and total CLint in HLM (whole organ metabolic clearance) calculated by the retrograde approach. The model accounts for the induction of CYP3A4, 2C9 and 2C19. It has been verified using the healthy population library available in Simcyp SImulator by default. The predictive performance of this model to predict herb-drug interactions with St John's wort was evaluated across a range of CYP substrates as detailed in the publication. https://link.springer.com/article/10.1007%2Fs40262-019-00736-6

Pitavastatin_V17R1_ASTAR_20190730

Model Files Publication

The submitted compound file for Pitavastatin uses ADAM, Full PBPK method 2, enzyme kinetics for metabolism and transporter kinetics for intestinal absorption, permeability limited liver model and MechKiM model. Tissue : Plasma partition coefficients have been modified to include data obtained from rat distribution studies. It has been used together with the unmodified Sim-Healthy Volunteer library file. https://www.altex.org/index.php/altex/article/view/1215

Darunavir&Ritonavir_V13R2_USFDA_20190719

Model Files Publication

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 These two files were used in combination (linked models). Note: Darunavir model also has fu,mic for DDI, and induction parameters for CYP1A that were not captured in Supplemental Table 1. Correction: Ritonavir's pKa2 should be 2.6 instead of 2.8 in Suppl. Table 1. https://accp1.onlinelibrary.wiley.com/doi/full/10.1002/jcph.936

Model at-a-glance

Absorption Model	First-Order
Volume of Distribution	Full PBPK (Method 2) Note: Kp scalar used
Route of Elimination	CYP2C19, CYP3A4, renal clearance
Perpetrator DDI	CYP2D6 Inhibitor
Validation	Proguanil and cycloguanil files were built using in vitro and clinical (Jeppersen et al., 1997) data 3 clinical studies describing single and multiple dose exposure of proguanil were used to verify the PBPK model. 66% of studies were within 2-fold, of which 33% 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 proguanil 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 With a large CL_Rcomponent and chemical relation to metformin, we hypothesise that proguanil may be a substrate for active transport in the kidney. However, owing to a lack of mechanistic information relating to active transport this cannot be built into the model.
Updates in V19	Modification of fm values Model converted from minimal to full PBPK distribution model Updated CYP2D6 IC50
