InSysBio, a pioneer in Quantitative Systems Pharmacology (QSP), modeling and simulation for drug development, announced the launch of application ‘PK/RO simulator for anti-PD-1 mAbs’. The application is based on the model allowing to predict pharmacokinetics and target binding in human for therapeutic antibodies against PD-1 receptor.
Complexity of novel therapeutics based on monoclonal antibodies makes the challenges in selection of first-in-human study dose or optimal dose due to their molecular properties. The aim of this work was to develop a minimal PBPK model of mAb disposition that will be capable to predict pharmacokinetics and target receptor occupancy (RO) in plasma and in the site of action on example of anti-PD-1 blocking antibodies such nivolumab, pembrolizumab, INCMGA00012 (MGA012), dostarlimab (TSR-042), MEDI0680 and sintilimab (IBI308).
Simulations showed that high doses with long period between administrations help to achieve higher peak RO in tumor but with that demonstrate lower trough RO. It seems like average receptor occupancy in tumor will be roughly similar over period of time. Q2W regimen provides more sustainable RO in tumor than Q3W regimen during administration of similar doses.
