Violet-Blue Light Inactivation of Bacteria in Chronic Wounds

Wound Heal Clinical Trial

Official title: Violet-Blue Light Inactivation of Bacteria in Chronic Wounds

Status Completed

Clinical Trial Summary

This four-week prospective clinical investigation will assess the safety and feasibility of a medical device without CE-marking. The medical device is a light-emitting-diode (LED) and is manufactured by VulCur MedTech Aps. Violet-blue light treatment is tested on a total of twenty-two patients with chronic wounds, divided into three groups, each group only receiving one dosage. Three dosages (low, medium and high) of violet-blue light treatment is tested. ID 1-7 are assigned to the low group, ID 8-15 are assigned to medium group and ID 16-22 are assigned to the high dosage group.

Clinical Trial Description

This is as prospective safety and feasibility clinical trial investigating violet-blue light treatment on chronic wounds. This clinical trial runs from Q3 2022 - Q2 2023. Twenty-two patients with chronic wounds will be included (n = 22) for a study-period of four weeks. Week 1 includes one baseline visit. Through Week 2,3 and 4 treatment is given six times with a span of 24-72 hours between every treatment visit. Week 4 includes one follow up-visit. Patients entering the study are assigned to three light dosage groups (low, medium and high) according to their study ID. ID 1-7 are assigned to the low group, ID 8-15 are assigned to medium group and ID 16-22 are assigned to the high dosage group. Between each dosage of light, there will be an evaluation of primary and secondary endpoints by the sponsor and the principal investigator. Light dosage is only escalated should this evaluation be deemed safe. To determine treatment safety skin reactions are assessed after treatment at: 0 minutes, 30 minutes, 24 hours, 48 hours, 5th treatment visit and at follow-up. Adverse Events and Adverse Device Events are evaluated at every visit for every dosage, feasibility is evaluated at follow-up for both patient and investigator. This investigation complies with the Good Clinical Practice concerning medical devices and follows the ISO standard DS/EN 14 155 and the Declaration of Helsinki ;
