Plain-language summary

Verruca vulgaris (VV), or the common wart, is a relatively prevalent and often frustrating cutaneous disease to treat. A single, highly effective therapy for the treatment of VV has not been found. Liquid nitrogen is considered the standard of care for VV and studies report a 44% to 47% cure rate. In search of more efficacious and convenient therapeutic options, a variety of lasers have been reported in the treatment of VV including the Nd:YAG laser (1064nm). Lasers offer the potential for decreased treatment associated pain, fewer office visits, higher cure rates and lower recurrence rates. However, many of the available published studies draw conclusions from case reports and small case series without any randomized controlled trials. A randomized, controlled study is needed to evaluate the efficacy of the microsecond Nd:YAG (1064nm) compared to conventional cryotherapy. This study will use the Cutera CoolGlide Nd:YAG laser that operates in the infrared spectrum at a wavelength of 1064nm. This a single site, double blind, randomized controlled clinical trial to evaluate the efficacy of the Nd:YAG laser (Cutera) in the treatment of verruca vulgaris of the hands and feet versus conventional liquid nitrogen therapy. The investigators hypothesize that there will be a significantly higher number of warts with complete resolution at 4 months follow-up in the Nd:YAG treated group versus the liquid nitrogen therapy group. The investigators also hypothesize that there will be a faster time to complete resolution of the verruca in the Nd:YAG treated group versus the liquid nitrogen treated group.

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.
