A drug for reducing antibiotic resistance and killing bacteria

Betatide is a novel synthetic cell-penetrating peptide that attacks bacteria in a fundamentally new way. It reduces antibiotic resistance development and act as an antibiotic.

Treatment of skin, lung, prosthetic joint infections and other infections caused by drug-resistant bacteria.


  • Novel mode of action, new target (beta-clamp)
  • Broad single agent effects towards priority pathogens (all ESKAPE pathogens).
  • Potentiate effect of other antibiotics. No cross-resistance.
  • Reduces the development of resistance towards current and future antibiotics.
  • Successful studies in animal models of skin and prosthetic joint infection, successful pilot in lung infection.
  • Repeated dose toxicity study by i.v. infusion to rats showed no major toxic effects


  • Patent granted in USA, Canada and several countries in Europe.
  • Pre-clinical stage, ongoing studies in other animal models of bacterial infection as well as toxicity studies.
