Overview

**G03-52-01** is an investigational lyophilized, fixed-dose cocktail of six full-length human or humanized IgG1 monoclonal antibodies: three directed against botulinum neurotoxin serotype A and three directed against botulinum neurotoxin serotype B. The antibodies bind non-overlapping toxin epitopes, neutralizing the toxins and promoting their clearance; the product is being developed as a medical countermeasure for pre-exposure and potential post-exposure prophylaxis against botulism, including aerosolized exposure. It is composed of the three-antibody products NTM-1631 and NTM-1632 and has completed Phase 2 evaluation in healthy adults following intramuscular administration.
