Plain English Summary

Background and study aims
Verrucae (or plantar warts) are extremely common. They usually develop on the soles of the feet. They are flat and white in appearance and often have a black dot in the centre. They can be painful if they are on a weight-bearing part of the foot. They are caused by the human papilloma virus (HPV). Although most verrucae will spontaneously disappear without treatment, many patients seek treatment because they have persisted for many years, can be unsightly, can be painful or have prevented them from doing sports and other activities. There are many different treatments available, including the needling procedure. This involves using a fine needle to puncture the verrucae multiple times under a local anaesthesia. The goal is to place infected cells into the dermis (second layer of skin), to stimulate an immune response to destroy the virus. To date there has only been one small trial testing to see if this treatment works and no health economic analysis has been undertaken. In this study we will investigate the clinical and cost effectiveness of the Falknor needling procedure for the treatment of verrucae.

Who can participate?
Adults aged 18 or older with a verruca that is suitable for both scalpel debridement and dry needling.

What does the study involve?
Participants are randomly allocated into one of two groups. For those in group 1, their verruca is treated with scalpel debridement. For those in group 2, their verruca is treated using a needling procedure. All participants are then followed up for the next 24 weeks to see whether their verruca has been successfully removed or reduced in size, if they experienced any pain after treatment and whether they satisfied with the treatment offered.

What are the possible benefits and risks of participating?
It is anticipated that both the treatments will help by either reducing the size of the verruca or healing it completely. There may also be a reduction in pain associated with the verruca. However, this cannot be guaranteed. The information obtained from this study may help to inform treatment in the future for people with verrucae.

Study information

Scientific title

EVerT2: dry needling versus nonsurgical debridement for the treatment of verrucae - a randomised controlled trial



Study hypothesis

The null hypothesis is that there is no difference in the clearance rates of verrucae as assessed by a blinded independent assessor at 12 weeks post randomisation between the two treatment groups.

Ethics approval

1. University of Salford, College of Health and Social Care Research Ethics Committee, 25/02/2015, ref: HSCR15/24
2. University of York, Department of Health Sciences Research Governance Committee, 18/02/2015, ref: HSRGC/2014/98/B

Study design

This will be a pragmatic, open, two-armed randomised controlled trial conducted in one centre. Participants with verrucae will be randomised in a 1:1 ratio to receive the needling procedure or to callus debridement.

Primary outcome measures

The participant’s verruca will be called the index verruca. In the case of a patient having multiple verrucae, the most painful or the largest verruca will be selected as the index verruca.
The primary outcome will be complete clearance of the index verruca at 12 weeks after randomisation as determined by blinded assessment by a HCPC registered podiatrist working at the clinical site. ‘Clearance’ of verruca will be defined as the restoration of normal skin upon close inspection, with the return of normal dermatoglyphics to the treated area of skin, i.e., uninterrupted skin striae as assessed by the podiatrist.

Secondary outcome measures

1. Clearance of the index verruca at 24 weeks as assessed in the same way as the primary outcome
2. Complete clearance of all verrucae at 12 and 24 weeks as assessed in the same way as the primary outcome
3. Self-reported clearance of all verrucae at 12 and 24 weeks
4. Self-reported time to clearance of all verrucae
5. Recurrence of verrucae at 24 weeks
6. Number of verrucae remaining at 12 and 24 weeks
7. Change in size of the ‘index’ verruca at 12 and 24 weeks (digital photographs of the verrucae will be taken for analysis using an appropriate software package to measure the surface area of the verruca(e))
8. Level of pain at 12 and 24 weeks
9. Level of pain 24 hours after the treatment
10. Number of treatments
11. Satisfaction with treatment at 12 and 24 weeks
