Canada401 participantsStarted 2026-01-13
Plain-language summary
This is a Phase 4 multi-center, group-randomized, crossover trial to compare nasal antimicrobial photodisinfection therapy (aPDT) with standard of care for prevention of surgical site infections in patients undergoing major elective, urgent, or emergent surgeries in a hospital setting. The main outcomes are to:
1. compare the efficacy, and
2. estimate the safety of applying nasal (aPDT) before surgery in reducing the incidence of SSIs within the initial 30 days after surgery compared to standard of care (SOC).
Participants in the intervention group will receive aPDT prior to surgery on the day of surgery.
Participants in the control group will receive standard of care surgical site prevention measures prior to surgery.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial on light-activated antimicrobial therapy to prevent surgical site infections is listed as completed — has the data been published yet, and if so, what did it show about whether the treatment actually reduced infection rates compared to standard prevention methods?
2Since this was a Phase NA (non-standard phase) study, what does that mean for how much is known about the safety and effectiveness of this light-activated approach, and would you consider it proven enough to use in my upcoming surgery?
3The trial tracked treatment-related adverse events within 30 days — were there any notable side effects reported with the light-activated therapy that I should weigh against my personal risk of getting a surgical site infection?
4Given that this trial was conducted in Canada and is now completed, is this light-activated antimicrobial approach something that's currently available or being used at our hospital, or is it still considered experimental?
5Compared to whatever this light-activated therapy was testing, what are the standard infection-prevention measures you'd use for my surgery, and do you think the results from this trial would change anything about my care plan?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Number of Participants with a Surgical Site Infection (SSI) within 30 days post surgery
Timeframe: Through 30 days post surgery
2
Percentage of Participants with Treatment-Related Adverse Events within 30 days after surgery.
. Pregnancy (current) or currently lactating. If patient is unsure of pregnancy status, a negative urine or serum pregnancy test (sensitive to 25 IU hCG) should be obtained within 14 days prior to surgery.
. Surgical indication of infection.
. History of surgery within 90 days prior to enrollment.
. Anticipated surgery other than the index surgical procedure prior to patient's completion of the study.
. Use of other nasal decolonization procedures on the day of surgery prior to the index procedure (mupirocin, povidone iodine, alcohol, etc.).
. Patient has any medical, social or psychiatric condition(s) or current substance abuse condition that, in the opinion of the investigator, would preclude the patient's ability to provide informed consent, or to comply with the study requirements.
. Enrollment in concomitant investigational research study in the past 30 days.
. Inability to tolerate insertion of the nasal light illuminator due to nasal obstructions or nares size, shape, or anatomical variants.
