The new article “Dose Selection for DuoBody®-CD40x4-1BB (GEN1042/BNT312) Using a mPBPK/RO Model Leveraging Preclinical and Clinical Data” by Gaurav Bajaj, Dmitry Shchelokov, Oleg Demin Jr, Homer C. Adams 3rd, Yan Feng, Leonid Gibiansky, Saskia van der Lee, Anandhi Johri, Merzu Belete, Alexander Muik, Porntula Panorchan, Özlem Türeci, Uğur Sahin, Tahamtan Ahmadi, Manish Gupta, Oleg Demin, Craig Thalhauser was published in CPT: Clinical Pharmacology & Therapeutics on May 10, 2025. 

Dmitry Shchelokov, Senior Modeler, highlights, "This work is devoted to a comprehensive approach to dose selection for GEN1042 (Duo Body®-CD40x4-1BB), a bispecific antibody that activates immune cells by simultaneous binding to CD40 and 4-1BB. Optimizing dose for bispecific antibodies is a non–trivial task, since the formation of trimolecular complexes upon binding to targets which is believed to mediate the effect cannot be quantified in vivo. The usage of a minimal physiologically based pharmacokinetic (mPBPK) model in combination with a receptor occupancy (RO) model allowed to justify the dose range at which a therapeutic effect is expected in a clinical trial."

The PBPK/RO model file is presented in the article. The model was developed using Heta compiler and can be transformed into different formats with its help.
