Potassium-titanyl Phosphate (KTP) Laser vs KTP Laser and Ivermectin Cream for Facial Rosacea
Switzerland22 participantsStarted 2023-09-12
Plain-language summary
Rosacea is a frequent chronic inflammatory disease affecting mainly the face but also eyes and scalp. Rosacea is classified into 3 types: erythemato-teleangiectatica, papulopustulosa and phymatosa. Treatments depend on the type and include topical and systemic antibiotics, azelaic acid, topical ivermectin, topical brimonidine, systemic isotretinoin as well as intense pulsed light (IPL) and laser therapies.
For treatment of telangiectasia and redness, laser and IPL therapies are the first choice. Vascular lasers, such as pulsed dye lasers (PDL) and potassium-titanyl phosphate (KTP) lasers as well as IPL, have demonstrated good efficacy in reduction of erythema and telangiectasias in patients with rosacea. However, these treatments are expensive and mostly not covered by the health insurance. Therefore, for patients it is important to receive the maximal effect and improvement after each single laser session.
Ivermectin is a semi-synthetic derivative of avermectin and has an anti-inflammatory effect as well as an antiparasitic effect on demodex mite. The latter is playing an important pathogenetic role in rosacea.
This randomized controlled study aims to compare the effect of KTP laser in combination with ivermectin 1% cream vs KTP laser alone in patients with facial rosacea.

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.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
