Capmatinib_RES_V21R1_Simcyp_20230615

The RES-Capmatinib_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 for V22. The verification for 200mg SD, 400mg SD, 600mg SD is performed in the Sim-Healthy Volunteer population and for the 400 mg BID in the Sim-Cancer population. A multiple plasma protein approach is used, accounting for HSA, AGP, IgG and lipoprotein inputs for the populations. The metabolism is simulated using Cytosolic Oxidases (rhAO) and CYP3A4. The Rosuvastatin DDI is using a 400mg BID dosing for Capmatinib in the fasted state.

Levonorgestrel_RES_V21R1_Simcyp_20220401

The V21 RES-Levonorgestrel file has been developed as a substrate of CYP3A4. The file was developed to capture the pharmacokinetics after administration of Levonorgestrel alone or in combination with Ethinyl Estradiol. A workspace and performance summary are available. Levonorgestrel is known to bind to the plasma protein Sex Hormone Binding Globulin and this has been captured in the file by utilising the other protein option in the population.

ValproicAcid_V21R1_NationalTaiwanUniversity_20231012

Three compound files for adults and 3 files for paediatrics are available for the parent compounds, Valproic Acid, reflecting the inputs required for EC tablets, tablets, and capsules, respectively. A compound file for the metabolite, 4-ene-Valproid Acid is available too. Details on the model assumptions and verification in V21R1 are available in the corresponding reference (DOI: 10.1002/psp4.13045) and supplement material on the journal (CPT: Pharmacometrics & Systems Pharmacology) website.

Date Updated: March 2024

The model at-a-glance

  Absorption Model

  • First-Order, fa and ka predicted by Caco-2 data

  Volume of Distribution

  • Minimal (optimized to IV data)

  Route of Elimination

  • fmCYP3A4 = 80, fmCYP2D6 = 20

  Perpetrator DDI

  • Inhibition of CYP2D6

  Validation

  • Model performance was verified in healthy volunteers and psychiatric patients. Two clinical studies with IV administration (7 to 10 mg) and ten clinical studies with oral administration (25 to 200 mg) were used for model verification. Simulations for eight of eleven clinical studies with a reported AUC were within 2-fold of the observed value.
  • The fmCYP1A2 was verified through simulations of chlorpromazine in smokers and non-smokers. The fmCYP2D6­ was verified through simulations of chlorpromazine coadministered with and without quinidine.

  Limitations

  • Model was developed using 10 mg IV and 100 mg PO. Use of 7-10 mg IV dosing and oral doses of 100-200 mg were verified, but predictions of oral doses <100 mg PO are overestimated.
  • Model does not include P-gp efflux.
  • Model is not verified for use in perpetrator DDI simulations with CYP2D6 substrates.
