Antabio SAS announced that it has raised €25m in a series B financing round with subscriptions from the AMR Action Fund, the EIC Fund and from the company’s historical investors including BNP Paribas Développement, Relyens Innovation Santé / Turenne Capital, IRDI Capital Investment and Christophe Ricard, the former President of OM Pharma.

This financing expands on the prestigious historical support received by the company through past multi-million-dollar awards from the Wellcome Trust, CARB-X, and ARPEGE.

This Series B will enable the company to complete the phase 2 clinical studies of MEM-ANT3310, a next generation antibacterial combination designed to provide a unique coverage of priority Gram-negative pathogens including OXA-carbapenem-resistantAcinetobacter baumannii (CRAB), KPC- and OXA- carbapenem-resistant Enterobacterales (CRE), and Pseudomonas aeruginosa (PA).

MEM-ANT3310 combines the well-known carbapenem meropenem (MEM) with ANT3310, a breakthrough serine-beta-lactamase (SBL) inhibitor developed by Antabio. ANT3310’s innovative structure completely inhibits Class A, Class C and Class D beta-lactamase enzymes and, in combination with MEM, represents a truly differentiated alternative to treat life-threatening infections due to drug-resistant Gram-negative pathogens, including Hospital-Acquired and Ventilator-Associated Pneumonia (HAP/VAP).
