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.

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.

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 (Altered Bioavailability and Pharmacokinetics in Crohn's Disease: Capturing Systems Parameters for PBPK to Assist with Predicting the Fate of Orally Administered Drugs - PubMed (nih.gov)).

TEST

Pitavastatin_V17R1_ASTAR_20190730
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

Brand Name(s) include: Jasoprim, Malirid, Neo-Quipenyl, Pimaquin, Pmq, Primachina, Primacin, Primaquina, Primaquine, Primaquine diphosphate, Primaquine Phosphate, and Remaquin

Disease: Malaria, Plasmodium vivax, Plasmodium ovale

Drug Class: Antimalarial

Related Files: Carboxyprimaquine (metabolite)

 The model at-a-glance

Absorption Model

  • First-Order

Volume of Distribution 

  • Full PBPK (Method 2)

Routes of Elimination

  • 89% MAO (entered using ‘user-UGT’ as a surrogate in the Simulator), 11% CYP2D6

Perpetrator DDI

  • CYP1A2 Inhibitor (in vitro)

Validation

  •  6 studies with single (15 to 45 mg) and multiple (15 mg QD) dosing. 100% of Cmax and AUC values within 1.5-fold.
  • No clinical DDI studies to verify contribution of metabolic routes

Limitations

  •  The active metabolites of primaquine have not characterized due to their instability. Therefore, a PBPK model for active metabolites cannot be developed in their own right.
  • Qualitative data suggests a role of P-gp, however, Jmax and Km values have not been measured.
  • There is evidence of enantiomer specific metabolism for primaquine which has not been considered in the current model.

Updates in Version 19

  • Updated in vitro protein and blood binding data and subsequent back calculation of CLint (retrograde approach)
    •  fu: 0.19 -> 0.26
    • B:P: 1 -> 0.82
  • Converted from minimal PBPK model to full PBPK model
