Bacteriophage Therapy TP-102 in Patients With Diabetic Foot Infection

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)).

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.
