Traditional approaches to antimicrobial drug development are poorly suited to combatting the emergence of novel pathogens. Additionally, the lack of small animal models for these infections hinders the in vivo testing of potential therapeutics. Here we demonstrate the use of the VelocImmune technology (a mouse that expresses human antibody-variable heavy chains and κ light chains) alongside the VelociGene technology (which allows for rapid engineering of the mouse genome) to quickly develop and evaluate antibodies against an emerging viral disease. Specifically, we show the rapid generation of fully human neutralizing antibodies against the recently emerged Middle East Respiratory Syndrome coronavirus (MERS-CoV) and development of a humanized mouse model for MERS-CoV infection, which was used to demonstrate the therapeutic efficacy of the isolated antibodies. The VelocImmune and VelociGene technologies are powerful platforms that can be used to rapidly respond to emerging epidemics. Traditional approaches for development of antibodies are poorly suited to combating the emergence of novel pathogens, as they require multiple steps of laborious optimization and process adaptation for clinical development. Here, we describe the simultaneous use of two state-of-the-art technologies to rapidly generate and validate antibodies against Middle East Respiratory Syndrome coronavirus (MERS-CoV), following a highly optimized process that links immunization to production of clinical material grade antibodies and developed promising clinical candidates for prophylaxis and treatment of MERS-CoV, and a humanized mouse model of infection that was used to evaluate our therapeutics. This study forms the basis for a rapid response to address the public threat resulting from emerging coronaviruses or other pathogens that pose a serious threat to human health in the future.
