Postherpetic Neuralgia Study


Postherpetic neuralgia (PHN) is a painful condition that affects the nerve fibers and skin. It often occurs as a result of shingles (herpes zoster). Shingles is caused by the virus which causes chickenpox. Most people get chickenpox during their childhood. Once they recover, the virus remains in the nervous system–it’s just inactive. But as a person ages, this inactive virus can become active again causing shingles. Shingles is an infection of a nerve and the area of skin around it. If the pain from shingles continues after the shingles are gone and over (within two to four weeks) it is known as postherpetic neuralgia. An average of one-in-five people with shingles will go on to have postherpetic neuralgia.

Albuquerque Clinical Trials is conducting a research study to evaluate an investigational medication in the treatment of PHN. In order to participate in the study, patients must meet the following criteria:

  • Patients 18+ years old
  • Patient has PHN (pain for more than  6 months but less than 6 years after shingles rash

Patients seeking to participate in the trial will be excluded if they meet any of the following criteria:

  • Patients with PHN affecting the face
  • Patients who have a history of fibromyalgia


Patients that qualify for participation in the study will at no cost receive:

  • Study medication
  • Study-related care from a local doctor
  • Compensation for time and travel
