At TAXIS Pharmaceuticals, our mission is clear: to combat antimicrobial resistance and save lives.

Antimicrobial resistance demands immediate, coordinated action from governments, healthcare providers, researchers, and the pharmaceutical industry. By investing in innovative solutions and fostering global collaboration, we can save lives.

TAXIS Pharmaceuticals is a biotech company dedicated to eliminating the threat of current and emergent antimicrobial resistance across a wide range of infectious diseases. We are currently researching new classes of anti-resistance agents that employ novel mechanisms of action.

We are focusing our science on the disruption of the foundation of bacterial cell wall architecture — including construction, maintenance, and growth — to address elemental drug resistance mechanisms.
