  • Known allergy to phage products.
  • Pregnant and/or breastfeeding.
  • Immunocompromised at screening in the judgment of the investigator.
  • Taking any systemic or topical antibacterial antibiotic within 2 weeks prior to the start of study treatment, for a condition other than Diabetic Foot Infection and DFO.
  • Taking any antiviral medication within 2 weeks prior to the start of study treatment and up through the last administration of study treatment.
