about arsanis


Redefining the Practice of Medicine for Serious Bacterial Infections

Arsanis is a leader in the discovery and development of monoclonal antibodies (mAbs) for the targeted immunotherapy of serious infections that cost hospitals time, money, and lives.

Monoclonal antibodies have transformed the treatment of a wide range of diseases from cancer to immune system disorders. In infectious diseases, mAbs target the pathogenic processes and features of specific bacteria, including antibiotic resistant strains, that give rise to serious infections. Unlike traditional antibiotics that often target both pathogenic and non-pathogenic bacteria in a non-specific way (e.g., broadly killing all Gram-positive bacteria), Arsanis’ mAbs selectively focus on specific pathogens and pathogenic processes. These targeted immunotherapies address critical infections while minimizing the collateral damage from antibiotic overuse, resistance, and microbiome disruption.

We believe that the ability to selectively and safely target causative pathogens provides a new way of preventing and treating infections in high-risk patients, and can generate both clinical and health economic benefits to patients and providers, ushering in a new era in infection prevention and management.

Arsanis was co-founded in 2010 by three infectious disease and industry veterans:

  • Eszter Nagy, MD, PhD, Chief Scientific Officer of Arsanis and Managing Director of Arsanis Biosciences GmbH;
  • Tillman U. Gerngross, PhD, Chairman of the Arsanis Board of Directors and CEO of Adimab; and
  • Errik B. Anderson, venture capitalist and President and Chief Operating Officer of Compass Therapeutics.
