About

TP-102 is a novel bacteriophage cocktail comprised of 5 (five) lytic bacteriophages against Staphylococcus aureus, Pseudomonas aeruginosa, and Acinetobacter baumannii. TP-102 is being developed for topical treatment of patients with wound infections including chronic ulcers; applied every other day (three times weekly (TIW)).

Full description

This is a Phase 2b, double-blinded, randomised, placebo-controlled multicenter study to determine the safety and efficacy of TP-102, in patients with diabetic foot infection. Eighty (80) patients with an infected diabetic foot ulcer and with at least one target bacterial strain (Pseudomonas aeruginosa, Staphylococcus aureus or Acinetobacter baumannii) susceptible to TP-102. Patients will be randomised to receive TP-102 or placebo, in a 1:1 ratio. Patients will be treated with 1 (one) mL of IP/ Placebo solution applied topically per cm3 of target ulcer. Patients will be treated with a total of 12 treatments in 28 days (+3 days) with at least one day of interval in between the days of treatment (no consecutive days of treatment are allowed) and a maximum of 3 (three) days without treatment. The titre of each bacteriophage in TP-102 is 1x109 (>1x108 and < 1x1010) plaque forming units per milliliter (PFU/mL). Assessments for efficacy and safety will include concomitant medications and AEs, local tolerability, clinical laboratory tests, vital signs, physical examination, wound biopsy/swab to determine the presence, speciation and TP-102 sensitivity of bacteria and target ulcer assessment.

Inclusion criteria

  • Aged ≥18 years old;
  • Established diagnosis of Diabetes Mellitus (type I or II);
  • Glycosylated hemoglobin (HbA1c) value < 12.0%;

Designated foot infection meets the following criteria:

  • Present for at least 3 weeks;
  • Below-ankle, full-thickness, cutaneous ulcer;
  • Wound area (after debridement, if applicable) 1 to 20.0 cm2;
  • PEDIS infection grade 2 or 3;
  • PEDIS perfusion grade 1 or 2;
  • PEDIS depth grade 1 or 2 (grade 3 at the discretion of the investigator e.g. if they have received appropriate surgical treatment to remove infected bones).
  • Diabetic foot infection with at least one target bacterial strain (Pseudomonas aeruginosa, Staphylococcus aureus or Acinetobacter baumannii), susceptible to the TP-102 bacteriophage cocktail, as assessed from wound cultures;
  • Patients of suitable physical and mental health as determined by the Investigator on the basis of medical history and general physical examination;
  • Patients of childbearing potential must have a negative serum pregnancy test at screening;
  • ICF signed voluntarily before any study-related procedure is performed, indicating that the patient understands the purpose of, and procedures required in the study and is willing to participate in the study.

Exclusion criteria

  • Infected study ulcer less than 2 cm away from other ulcers, in the case of multiple ulcers;
  • Patient receiving hyperbaric oxygen therapy (HBOT), negative pressure wound therapy (NPWT), bioengineering skin (BES) substitutes and/or growth factors;
  • Patient which, in the opinion of the investigator, may not comply with study related procedures;
  • Presence of active malignant or benign tumors of any kind, (with exception to nonmelanoma skin cancer as per investigator's discretion);
  • Being pregnant or breastfeeding;
  • Currently participating in another clinical trial or having participated in a previous clinical trial with receipt of an investigational product within 30 days of the first administration of IP;
  • A condition that, in the opinion of the Investigator, could compromise the well-being of the patient or course of the study, or prevent the patient from meeting or performing any study requirements;
  • Participants with hypersensitivity to any component of investigational products.
