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 * character as a wildcard at the end of a alphanumeric search term. The search term must start with at least one character before the wildcard. E.g., Rifam* will get you “Rifampicin” and “Rifampin”.
You can also use a * character as a wildcard in the middle of a alphanumeric search term. The search term must still start with at least one character before the wildcard. E.g., Rif*in will also get you “Rifampicin” and “Rifampin” .
You can also use a * character as a wildcard at the start of a alphanumeric search term. However you must use forward slashes to delimit the search term and use a point before the wildcard. E.g., /.*picin/ will only get you “Rifampicin”.

Fenebrutinib_RES_V21R1_Simcyp_20230615

Model Files Publication

Prepared: June 2023 The RES-Fenebrutinib_V21 model has been developed primarily as an inhibitor of hepatic OATP1B1 and OATP1B3, and intestinal BCRP using the New GI physiology in Simcyp V21 with altered GI tract population inputs that became default in V22. The RES-Fenebrutinib is verified as solution formulation for 100mg SD, 200mg SD, and 200mg BID. The Rosuvastatin DDI is using a 200 mg BID dosing for Fenebrutinib. Example workspaces for the Fenebrutinib PK and the DDI with Rosuvastatin are attached. The BCRP component of Rosuvastatin (V21 using the New GI physiology) was optimised using Eltrombopag and then verified with other BCRP-Inhibitors available on the members area or within the Simcyp Simulator, see attached ‘BCRP-Inhibitor V21’ document for details.

Doxycycline

Model Files Publication

Brand Name(s) include: Adoxa, Doryx, Monodox, Oracea, Periostat, Vibramycin, Vibra-tabs

Disease: Malaria

Drug Class: Antibiotic

Date Updated: June 2022

The model at-a-glance

Absorption Model	First-Order
Volume of Distribution	Full PBPK (Method 2) Note: A Kp scalar (0.3) was used in the model
Route of Elimination	Biliary = 66%; Renal= 44%
Perpetrator DDI	None
Validation	Seven clinical studies describing single and multiple dose exposure of doxycycline were used to verify the PBPK model. The model predicted AUC values in 86% of studies within 2-fold (100% if one simulated/observed ratio is rounded down from 1.52 to 1.5), of which 57% were within 1.5-fold.
Limitations	Model is not verified at doses below 100 mg or about 200 mg (dose-linearity of doxycycline is uncertain) Model assumes hyclate, monohydrate and hydrochloride formulations are bioequivalent Model is not developed for the prediction of IV doxycycline Model was developed and verified primarily in healthy volunteer studies (except Newton et al. 2005); appropriateness of extrapolation to acute malaria patients is unknown
Updates in V19	Updated in vitrodata fu: 0.142 -> 0.23 B:P: 1.5 -> 0.78 Converted from minimal PBPK model to full PBPK model Elimination changed from user input IV clearance to retrograde clearance with biliary clearance and additional hepatic clearance

Lumefantrine

Brand Name(s) include: Coartem (artemether, lumefantrine), Riamet (artemether, lumefantrine)

Disease: Malaria

Drug Class: Antimalarials

The model at-a-glance

Absorption Model	First-Order
Volume of Distribution Details	Full PBPK (Method 2) Note: Kp scalar and Kp adipose used
Route of Elimination	CYP3A4 (40%); non-specific hepatic metabolism (60%)
Perpetrator DDI	CYP2D6 Inhibitor
Validation	Two clinical studies describing single dose exposure and two describing multiple dose exposure of lumefantrine were used to verify the PBPK model. The single dose exposures were within 2-fold of observed for both studies. The multiple dose exposures were within 1.25-fold of observed for both studies. Clinical DDI studies with rifampicin and efavirenz in healthy volunteers where lumefantrine was the victim of CYP3A4-mediated DDIs were over-predicted (>2-fold) using the PBPK model. An alternative clinical efavirenz DDI study in HIV patients and a clinical DDI with ritonavir in healthy volunteers were well predicted (within 1.25-fold of observed). As the effect of CYP3A4 inhibition was independently verified and there appeared to be variability in the extent of induction on lumefantrine PK, the fmCYP3A4 of 40% was considered verified.
Limitations	Plasma concentrations of lumefantrine following a single dose are less accurately predicted than those following multiple dose administration. As the Day 7 plasma concentrations following repeat administration of lumefantrine, are more critical (linked to cure rates) than after the first dose, this was deemed acceptable. The model can be used to prospectively predict CYP2D6-mediated DDIs but in the absence of verification of CYP2D6 inhibition, this should be accompanied by appropriate sensitivity analysis.
Updates in V19	Updates in vitro data based on new information B:P ratio 0.6 -> 0.55 CYP2D6 Ki (µM) 2.2 -> 1.8
