Unfortunately, if you meet any of the following, this study is not the right fit for you:

  • Anyone who has other pains that cannot be clearly differentiated from PHN.

How long will the study take?

  • 1-week safety follow-up period
  • 10 visits to the trial site

What is the purpose of this study?

This study aims to assess the efficacy of a potential new treatment for postherpetic neuralgia (PHN) versus placebo in the management of PHN-related pain. 

What is Postherpetic Neuralgia (PHN)?

PHN is the most common complication of shingles. The condition affects nerve fibres and skin, causing burning pain that lasts long after the rash and blisters of shingles disappear.It has been estimated that approximately one in five people with shingles will get PHN, with those aged 50 and over particularly at risk. Many people with PHN make a full recovery within a year. But symptoms occasionally last for several years or may be permanent.

The main symptom of PHN is nerve pain in an area of your skin that was previously affected by shingles. The pain may come and go or be continuous, and might be described as burning, stabbing, shooting, aching, throbbing or like electric shocks.

The affected area may also:

  • Feel intensely itchy
  • Be more sensitive to pain than usual
  • Feel painful as a result of something that would not normally hurt, such as a light touch or cool breeze
