FIGHTING
Drug Resistant Infections

We are a privately-held clinical-stage biopharmaceutical company developing novel antibacterials targeting drug-resistant pathogens that are deemed a critical priority by the WHO.

Antimicrobial Resistance

A Growing Global Emergency

5–10% of patients

Acquire a healthcare-associated infection in acute care hospitals

1.14M deaths (2021)

Attributable to bacterial AMR

10M deaths / year (2050)

Projected global mortality from antimicrobial resistance

US$412B

Potential annual additional healthcare expenditure globally due to AMR

Who we are

Expert and Complementary Team

Antabio is a clinical stage biopharmaceutical company developing novel antibacterial treatments targeting drug‑resistant infections identified by WHO and CDC as critical priorities, with a particular focus on life-threatening hospital infections.

The company’s lead program, Meropenem-Pilabactam (MEM-PIL, formerly MEM‑ANT3310), is a next‑generation β‑lactam/β‑lactamase inhibitor (BL/BLI) combination designed to treat multi drug-resistant infections in hospital wards and ICUs. Antabio is supported by leading strategic and institutional investors such as the AMR Action Fund, EIC Fund, BNP Paribas Développement, Turenne/Relyens Santé, and IRDI Capital Investment. 

Our mission

Fighting Resistance

Our mission is to develop innovative, highly differentiated antibacterial therapies for patients suffering from severe, hard-to-treat infections caused by multidrug-resistant Gram-negative bacteria.

We focus on delivering effective solutions targeting WHO and CDC priority pathogens, with a particular emphasis on life-threatening hospitalacquired infections. Through scientific excellence, strategic development, and a diversified pipeline, we aim to restore the efficacy of antibiotics and play a leading role in the global fight against antimicrobial resistance.
