The 4β-hydroxycholesterol (4β-OHC) file is an endogenous biomarker for CYP3A activity mainly measured to evaluated potential CYP3A induction in vivo. The 4β-OHC file was developed as a primary metabolite of the parent compound, cholesterol. As the compound requires specific system parameter inputs for endogenous CYP abundance scaling, the parent-metabolite file is available within a workspace containing the required system parameters. The parent-metabolite file has been developed in the Simcyp Simulator V23 and details of the file performance are described in Karkhanis et al., 2024 (PMID 39458613) and in a compound summary that provides the key pharmacokinetic features of cholesterol and 4β-OHC considered within the model.
The RES-Simvastatin lactone and RES-Simvastatin acid models within the Simcyp Compound Repository have been developed as substrates of CYP3A4, CYP2C8, BCRP (simvastatin lactone), CES1 (simvastatin lactone) and OATP1B1 (simvastatin acid). Additionally, the models account for the interconversion between the lactone and acid forms in the acidic environment of the stomach. Note: Before running a simulation, modify the population to account for gastric luminalmetabolism. To do this, follow these steps:

https://dmd.aspetjournals.org/content/47/11/1291/tab-article-info This workspace was developed to recapitulate the magnitude of drug-drug interaction reported between Rivaroxaban and Verapamil as reported by Greenblatt et al. (https://pubmed.ncbi.nlm.nih.gov/29194698/) Note 1: In Table 1 of the publication the Caco-2 Papp (pH 7.4:7.4) was reported as 8 x 10-6 cm/s; however, the Rivaroxaban file in the workspace is using a Caco-2 Papp (pH 7.4:7.4) of 21.8 x 10-6 cm/s. This Papp is in line with the reported scalar in the EXCEL outputs and the Table 1. The obtained Rivaroxaban plasma concentration time profile is in line with the reported Figure 2C in the publication. Note 2: In Table 1 of the publication, input data for Mech KiM are stated; however, the Rivaroxaban file in the workspace is using a User Input for the renal clearance of 3.1 L/h; while the input data for Mech KiM are included in the compound file, they are not activated within the workspace, which is mimicking a DDI with Verapamil and Norverapamil. Note 3: Bile:micelle parameters were changed from 3.4 to 3.5.

The cabozantinib model has a status of a research compound file. The model has been developed as a substrate of CYP3A4. The PBPK model was designed to recover pharmacokinetics of cabozantinib following single or multiple dose administration of cabozantinib.
This document provides:
1. Examples of model performance following oral administration of cabozantinib.
2. A summary of the key pharmacokinetic features of cabozantinib considered within the model.
