About Nosopharm


At Nosopharm our mission is to discover and develop first-in-class therapies to treat infectious diseases, especially in the context of antimicrobial resistance.

Infectious diseases are a major cause of global mortality, leading to more than 8 million deaths in 2019, before the Covid-19 pandemic crisis. In 2019 an estimated 4.95 million deaths were associated with bacterial antimicrobial resistance. The increase in antimicrobial resistance, making infections much harder to treat, represents a critical challenge for global health.

In this context, Nosopharm aims to contribute to the fight against infectious diseases, especially antimicrobial resistance, by discovering novel anti-infective therapies. Our R&D programs are based on our unique expertise in the exploitation of the bacteria Photorhabdus and Xenorhabdus.

Nosopharm’s drug discovery platform is based on these two underexplored antimicrobial-producing bacteria. Nosopharm is the only biotech company to explore the bacteria Photorhabdus and Xenorhabdus for anti-infective applications.
