Bacteriophage therapy for diabetic foot infections

A Phase 2 CT to Evaluate the Safety and Efficacy of Topical Administration of Bacteriophage Therapy TP-102 in Patients With DFI

PHASE2 · Technophage, SA · NCT05948592

This study is testing a new bacteriophage treatment for people with infected diabetic foot ulcers to see if it can help clear the infection better than a placebo.

What this trial studies

This Phase 2b clinical trial evaluates the safety and efficacy of TP-102, a novel bacteriophage cocktail targeting specific bacteria associated with diabetic foot infections. The study involves 80 patients with infected diabetic foot ulcers, who will be randomly assigned to receive either TP-102 or a placebo. Treatment consists of topical application of the bacteriophage solution three times a week over a 28-day period. Assessments will include monitoring for adverse events, local tolerability, and the effectiveness of the treatment in eradicating the targeted bacterial strains.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a diagnosis of diabetes and a specific type of infected foot ulcer meeting the study criteria.

Not a fit: Patients with diabetic foot infections not caused by the targeted bacterial strains or those with severe systemic infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients suffering from diabetic foot infections, potentially reducing the need for antibiotics and improving healing outcomes.

How similar studies have performed: While bacteriophage therapy is a novel approach, there have been preliminary studies suggesting potential success in similar applications, though this specific combination has not been extensively tested.
