Is this trial a fit for you?

Likely a good fit

Probably not a fit

Patients with severe complications such as critically impaired circulation, recent myocardial infarction or stroke, or those requiring intensive care may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial involves 202 participants with diabetic foot ulcers who will be randomly assigned to receive either Hypochlorous Acid (HClO) or Polyhexamethylene biguanide (PHMB) for cleaning their wounds. The treatment will occur twice a week until the ulcers heal or for a maximum of 24 weeks. The primary goal is to determine which cleaning agent is more effective in achieving complete healing of the ulcers, while secondary objectives include assessing healing time, ulcer size, depth, antibiotic use, and quality of life. The study is designed to be double-blind and controlled to ensure unbiased results.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for diabetic foot ulcers, improving healing rates and patient outcomes.

How similar studies have gone: Previous studies have shown varying degrees of success with similar antimicrobial treatments, but this specific comparison of HClO and PHMB is novel.
