Diabetic Foot Infection | Biological: TP-102 Other: Placebo | Phase 2 |
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.

Experimental: TP-102
Patients will be randomly assigned in a 1:1 ratio to one of two treatment arms at Day 1. The wound standard of care (SoC) procedures shall be in accordance to each sites normal DFI routine.

Biological: TP-102
Patients randomised to TP-102 will receive 1 (one) mL of IP solution, applied topically per cm3 of target ulcer. The titre of each bacteriophage in TP-102 is 1x109 PFU/mL (>1x108 PFU/mL and <1x1010 PFU/mL). All patients randomised to TP-102 will receive the same concentration per mL. TP-102 will be applied to the target ulcer using a syringe without a needle. The volume of TP-102 to be administered will be determined from the wound volume assessment at the previous visit through an automated wound measurement system (Silhouette), except on the first day of treatment where the amount applied will be determined based on the wound volume determined at that time using the automated wound measurement system (Silhouette). |
Placebo Comparator: Placebo
Patients will be randomly assigned in a 1:1 ratio to one of two treatment arms at Day 1. The wound standard of care (SoC) procedures shall be in accordance to each sites normal DFI routine.
|
Other: Placebo
Patients randomised to placebo, the volume calculated to be administered will be determined from the wound volume assessment at the previous visit through an automated wound measurement system (Silhouette), except on the first day of treatment where the amount applied will be determined based on the wound volume determined at that time using the automated wound measurement system (Silhouette). |
