Zepatier_V19R1_Pfizer_20210804
An optimized Rosuvastatin (V19) model was used and DDIs predominantly driven by gut BCRP inhibition are reasonably recovered. Altogether, the following inhibitors were used: Capmatinib Fenebrutinib Fostamatinib Itraconazole Zepatier The workspace represents the DDI between Rosuvastatin and Zepatier. Zepatier is an antiviral medicine that contains the active substances elbasvir and grazoprevir. The two compounds were simulated as Inhibitor 1 and Inhibitor 2, respectively.

Darunavir&Ritonavir_V13R2_USFDA_20190719
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
Fenebrutinib_V19R1_Pfizer_20210804
An optimized Rosuvastatin (V19) model was used and DDIs predominantly driven by gut BCRP inhibition are reasonably recovered. Altogether, the following inhibitors were used: Capmatinib Fenebrutinib Fostamatinib Itraconazole Zepatier The workspace represents the DDI between Rosuvastatin and Fenebrutinib. Notes: - The fuGut in the inhibitor file is set as user input to 1. - An additional systemic clearance of 1.1 L/h is included in the submitted file.
