Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1 - Platelet-rich plasma (PRP) is an autologous blood product that will be used to inject into the vulva at the lichen sclerosus lesion. PRP is the study treatment.

Arm 2 – Normal saline will be used to inject into the vulva at the lichen sclerosus lesion as a placebo in this trial.

Informational materials will be the Participant Information and Consent form. The principal investigator will deliver the intervention and placebo treatment. Participants will have two treatments 6 weeks apart at FBW Gynaecology Plus. Assessment is at 6 weeks, 6 months, and 12 months.

The first visit is for initial assessment and randomization into the study. The first treatment may occur at the time of the initial assessment. A second treatment will be 6 weeks after the first treatment. The injections into the vulva will be a maximum of 4 mls of PRP or placebo. It may be less if it becomes evident through visual inspection that the tissue cannot hold the maximum amount.

Subsequent clinical reviews will be at 6 months and 12 months after the first treatment.
Intervention code [1] 301775 0
Treatment: Other
Comparator / control treatment
The normal saline syringe will be injected underneath the vulval mucosa at the area affected by lichen sclerosus using a 30-gauge needle.

The technique of injection that will be employed will be a maximum of 4 mls. It may be less if it becomes evident through visual inspection that the tissue cannot hold the maximum amount.

Statistical methods / analysis
Based on the pilot study on 28 patients (Behnia-Willison 2016), 80% of the PRP-treated patients experimented an improvement of their condition. Assuming a difference of 30% between PRP treatment and normal saline placebo at 12 months, an alpha risk of 5% and a power of 80%, a sample size of 31 subjects for the PRP group and 31 subjects for the normal saline group is required. Assuming that up to 10% subjects may be lost to follow-up or withdrawn, a sample size of 34 subjects for the PRP group and 34 subjects for the normal saline group is required, for a total sample size of 68 patients.

Summary
Brief summary
This is a randomised control trial to compare platelet-rich plasma (PRP) against placebo (normal saline) as a treatment for women with symptomatic vulval lichen sclerosus (LS). LS is an acute and often chronic inflammatory dermatosis with autoimmune pathogenesis (Neill et al., 2010). It is a debilitating condition with serious consequences for the patient’s physical, emotional and sexual health (Newman et al., 2015). The management of LS is aimed at controlling symptoms, mainly severe vulvo-vaginal pruritus. Some women with LS are either unresponsive to corticosteroids or hesitate to use them. There are small studies to demonstrate PRP can improve vulvar LS. Therefore, this study is to assess the efficacy of PRP for treatment of vulvar LS.
