Both paratopes can be independently selected and combined into the desired bispecific DutaFabs in a modular manner. X-ray crystal structures illustrate that DutaFabs are able to bind two target molecules simultaneously at the same Fv region comprising a VH-VL heterodimer. In the present study, this platform is applied to generate DutaFabs specific for VEGFA and PDGF-BB, which show high affinities, physico-chemical stability and solubility, as well as superior efficacy over anti-VEGF monotherapy in vivo. These molecules exemplify the usefulness of DutaFabs as a distinct class of antibody therapeutics, which is currently being evaluated in patients. DutaFabs are engineered therapeutic Fab fragments that can bind two targets simultaneously.,Beckmann R, Jensen K, Fenn S, Speck J, Krause K, Meier A, Roth M, Fauser S, Kimbung R, Logan DT, Steegmaier M, Kettenberger H Nat Commun. 2021 Jan 29;12(1):708. doi: 10.1038/s41467-021-20949-3.
