Researchers from Columbia University and collaborators described the mechanism used by mAb 77, a single-chain variable fragment (scFv) derived from monoclonal antibody (mAb 77.4) targeting MeV F peptide, to neutralize viral infection.
At the Congress of the European Academy of Neurology, researchers from Dianthus Therapeutics Inc. presented preclinical data on DNTH-103, a monoclonal antibody engineered to selectively target the active form of complement C1s.
Kbio Inc. has obtained IND clearance from the FDA for EV68-228-N, a human monoclonal IgG1 against the capsid of enterovirus D68 (EV-D68) designed as an intravenous therapeutic for the treatment of acute flaccid myelitis.
