PICO Venous Leg Ulcers (VLU) Reimbursement Study

This is a national, multicentre, pragmatic, randomized, controlled superiority study in which PICO treatment with compression therapy will be compared against Standard of Care (i.e. traditional wound dressings with compression therapy). There will be two parallel treatment arms with a 1:1 allocation ratio and a stratification on wound duration and size. There will be an additional blind assessment for the primary outcome measure.

Approximately 37 investigational sites located in France will be enrolled. At each site, a community-based practitioner (general practitioner or specialist) will be enrolled as Principal Investigator (PI). District nurses will be responsible for providing wound care in homecare setting. Duly informed and eligible patients will complete an inclusion visit after which they will enter in a 2-week run-in period in which subjects will be treated with standard of care. After these 2 weeks of run-in, eligibility to randomization will be assessed using pre-specified criteria listed in the protocol, that aim to confirm that the wound does not respond to an adequately conducted standard of care in a satisfactory manner, including subject compliance with compression therapy.

Upon randomization, baseline data will be collected, and each subject will be followed-up by the PI for 12 weeks. The PI will conduct 3 visits, i.e., at Week 4 (D28±3 days), Week 8 (D56±3 days), and Week 12 (D84±3 days). Relevant study data will be collected at these visits. In the event wound healing is observed during the 12-week follow-up period of the study either by the PI or by the home care nurse, a Wound Healing Confirmation Visit needs to be conducted with the PI 2 weeks later (±3 days) to confirm that the wound is still healed. Only wounds still healed at the wound healing confirmation visit will be counted as "healed" in the primary endpoint analysis. This means that for wounds that are not healed by Week 12, the visit with the PI at Week 12 will be the final study visit for the subject. Following, because a Wound Healing Confirmation Visit needs to be conducted 2 weeks (±3 days) following the initial observation of wound healing, which can occur at any time throughout the 12 week follow-up period, the Wound Healing Confirmation Visit can occur at any time as well, but at the latest 2 weeks (±3 days) following the visit at Week 12, i.e. at week 14±3 days.

In between study visits with the PI, patients are cared for at home by their home care nurse who will also be trained on the study. The study nurse will be collecting study related data as well using a secure mobile application.
