Botulinum Toxin Treatment for Localized Vitiligo

Saudi Arabia10 participantsStarted 2009-04

Plain-language summary

Background: New light shed on the cholinergic aspects of vitiligo pathophysiology. It was found that acetylcholine concentration increased with a significantly reduced expression of acetylcholinesterase in vitiliginous patches that return to normal up on repigmentation. Objective: The investigators will undertook this controlled, prospective pilot study to evaluate the efficacy and safety of botulinum toxin A in patients with localized vitiligo. Methods: 10 patients with focal or segmental vitiligo will be recruited. For each patient with focal vitiligo, one or two vitiliginous patches will be treated. The other patches will be used as control. For each patient with segmental vitiligo, half of the lesion will be treated. The other half will be used as a control. Botulinum toxin will be injected. The response will be analyzed at the initial visit, two weeks and at two and six months after therapy.

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.

What they're measuring

the percentage of repigmentation in the previously depigmented patch, in form of color or size changes and folliculocentric repigmentation, of the treated and the control patches.

Timeframe: Patients will be re-examined at 2 wk, 2 and 6 months after therapy.
