A response (defined as decrease in wound surface area) was observed in seven patients (77.8%). Of these, four patients (44.4%) achieved wound closure on average 4 months (127.5 days) following the beginning of the treatment. Two patients did not respond to the investigational treatment. Quality of life improved over time throughout the study. Compliance was excellent, with 93.2% of visits completed as per protocol. Safety was unremarkable, with only four treatment-emergent-related adverse events, for which no specific intervention was required.Conclusion: The BioPhotonic System was shown to be safe and extremely well tolerated. It also demonstrated potential in terms of wound closure, wound surface area decrease, and wound bed preparation. Keywords: biophotonics, light, photobiomodulation, venous leg ulcers
