Prepared: June 2023 The RES-Velpatasvir_V21 model has been developed primarily as 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. There are limited PK and DDI studies available for Velpatasvir and it is generally used in a fixed dose combination using 100 mg Velpatasvir. Thus, the Velpatasvir file is a Fit-for-purpose PBPK model for 50 mg to 100 mg QD. The Rosuvastatin DDI is a 100 mg QD study. Example workspaces for Velpatasvir 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.
PBPK model of Transdermal Selegiline along with its metabolites. Note 1: The workspace is set up to mimic the clinical data reported by Azzaro et al., Journal of Clinical Pharmacology, 2007;47:1256-1267 Pharmacokinetics and Absolute Bioavailability of Selegiline Following Treatment of Healthy Subjects With the Selegiline Transdermal System (6 mg/24 h): A Comparison With Oral Selegiline Capsules. Note 2: A 6 mg/24 h dose corresponds to the release rate from a 20 mg/20 cm2 patch. The EMSAM®, SELEGILINE TRANSDERMAL SYSTEM, drug label from November 2012 states "EMSAM systems are available in three sizes: 20 mg/20 cm2, 30 mg/30 cm2, and 40 mg/40 cm2 that deliver, on average, doses of 6 mg, 9 mg, or 12 mg, respectively, of selegiline over 24 hours."
