Antabio is a French early-stage drug discovery company developing compounds for multi-drug resistant bacterial infections. The 2 lead programs are Metallo Beta-Lactamases inhibitors against E. coli NDM-1 strains and Pseudomonas Biofilms inhibitors in chronic respiratory infections. In 2013 and 2015 received funding from Wellcome Trust for EUR 4.7M and EUR 4 M respectively. The first candidate is a novel, safe and efficacious inhibitor of bacterial MBLs. It will be co-administered with a carbapenem to treat hospitalized patients suffering from complicated Gram-negative infections. The second candidate is an inhaled drug which can be used as an adjunct to existing antibiotic therapy and which will reduce the frequency and severity of Pseudomonas exacerbations by targeting both the virulence and persistence of biofilm-adapted infections.
