The RES-Darolutamide_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. Darolutamide shows dose proportional PK between 100 to 700 mg BID. It is a BSCII compound, where the metabolite is a potent BCRP-inhibitor too. Darolutamide is possibly a weak CYP3A inducer in the clinic. The back-conversion of Keto-darolutamide to Darolutamide is efficiently catalyzed via cytosolic AKR1C3 (in vitro). This back-conversion is also observed in incubations of feces under anaerobic conditions (in vitro). In the compound fit-for-purpose compound file, the back-conversion was fixed to recover the concentration time profile for the 600 mg BID as this was the dose for the reported Rosuvastatin DDI. Note that two workspaces need to be run to simulate the Darolutamide DDI and then the results have to be combined. This is due to having to switch the position of Darolutamide and rosuvastatin (limitations on functionality on inhibitory metabolite in the Simcyp Simulator currently).
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.
