Regeneron proposes gene therapy re-dosing solutions at ASGCT
In non-human primates, an anti-CD40 mAb and a CD20 x CD3 bispecific allow AAV re-dosing
Regeneron is taking on the AAV gene therapy re-dosing challenge with two antibody-based strategies designed to lower neutralizing antibody levels enough to enable repeat dosing. The company’s genetic medicine division has cleared the first hurdle, demonstrating that re-dosing is possible in non-human primates.
