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.

Related Files: DHA (partner in fixed dose combination)

The model at-a-glance

  Absorption Model

  • First-Order (dose and food-dependent fa – saved in different models)

  Volume of Distribution

  • Full PBPK (Method 2)
  • Notes: Includes a Kp scalar and Kpadipose

  Route of Elimination

  • CYP3A4 (80%), CYP2C9 (10%), CYP2C19 (10%)

  Perpetrator DDI

  • CYP3A4 Inhibitor

  Validation

  • Two clinical studies with fasted and fed groups at varying dose levels describing single and multiple dose exposure of piperaquine were used to verify the PBPK model. All of the simulated studies were within 1.5-fold of the observed values. 
  • A clinical DDI study where piperaquine was the victim of a CYP3A4-mediated DDI was accurately recovered using the PBPK model as well as a CYP3A4 perpetrator DDI with the sensitive substrate midazolam.

  Limitations

  • Requires separate files for low and high dose due to dose-dependant fa​
  • Cmax overprediction, likely due to formulation differences​
  • Additional verification for DDIs would be ideal although studies are currently not available in literature

  Updates in V19

  • Updated in vitro­ data
  • LogP
  • Converted model to full PBPK with Vss predicted through Method 2

 

CrohnsDiseasePopulation_V19R1_UniversityOfManchester_20230322

This model is a Crohn's disease (CD) population model for adult patients, created in Simcyp version 19. Alteration of GIT parameters and other physiological parameters like albumin level incorporated based on literature available data of inactive state of CD. The demographic and formulation information are based on the published in vivo pharmacokinetics data of midazolam and budesonide in CD patients. The model details and results are published in 2022 DOI: 10.1007/s40262-022-01169-4 

Dolutegravir_RES_V23R1_Simcyp_20240404

Simcyp developed dolutegravir compound file. Compound summary including an outline on the current status and limitations included.

The RES-Dolutegravir model has been developed primarily as a UGT1A1 and CYP3A4 substrate, and as an inhibitor of renal MATE1 and OCT2 transporters. MATE1 and OCT2 inhibition parameters have been optimized to capture impact of dolutegravir on metformin pharmacokinetics but have not been independently verified. In vitro observed inhibition of MATE2-K by dolutegravir has not been included as the parameter could not be optimized and verified with the substrate models and clinical data available at the time of dolutegravir model development.

Hydroxychloroquine_V18R1_PekingUniversityThirdHospital_20200323

The HCQ file was developed by Peking University Third Hospital and kindly shared on our Members Area. Please cite the original reference in which the file was presented (see link to publication) and please share your simulation results ASAP. Considering the current public health situation, we are happy to coordinate the simulation efforts around this PBPK model. The submitted compound file for HCQ is using first order absorption model, full-PBPK, Method 2. Perfusion limited lung model was developed. Additional organ was defined as lung and changed the tissue blood rate flow as 0.2. Clearance of HLM was estimated based on fm. It has been verified with a Caucasian healthy volunteer population library that was unmodified from the Sim-Healthy Volunteer library file. Please note a custom dosing for 5 days has been included in the file. https://pubmed.ncbi.nlm.nih.gov/32150618/
