Abnormal fusion of the FGFR2 gene, encoding the fibroblast growth factor receptor 2, occurs in several types of cancer, including in up to 15% of cases of intrahepatic cholangiocarcinoma.
Pierre Fabre SA and Redridge Bio AG have signed an exclusive R&D collaboration and license agreement to identify and develop biparatopic antibody drug candidates against multiple targets, with a focus on precision oncology, dermatology and rare diseases. The agreement provides for participation by Pierre Fabre in Redridge’s series A financing, as well as up-front, milestone and future sales royalty payments.
The anti-HER2 biparatopic antibody (bpAb) KJ-015 was rationally designed at Shanghai Bao Pharmaceuticals Co. Ltd. by leveraging published antibody-antigen structures to share common light chain with two Fab arms, resulting in functionally balanced high affinity for two HER2 nonoverlapping epitopes.
