Generation Bio Co. (GBIO) Reports Poor Results for Preclinical Studies for Hemophilia A Program

On December 14, 2021, Generation Bio issued a press release that "provided an update on factor VIII expression from a series of mouse and companion non-human primate (NHP) studies in hemophilia A, as well as an update on the development of its non-viral genetic medicine platform. Generation Bio’s proprietary genetic medicine technology comprises a closed-ended DNA (ceDNA) delivered via a novel, cell-targeted lipid nanoparticle (ctLNP).” The Company disclosed results that showed that in mice, ceDNA generated peak mean human factor VIII expression of 205% of normal at 2.0 mg/kg, and advised that “[a]dditional optimization is needed to translate the improvement in potency and reduction in variability observed in mice to [non-human primates], and to support nomination of a development candidate for the company’s hemophilia A program[.]" On this news, Generation’s stock price fell $7.91 per share to close at $5.99 per share on December 14, 2021.
