About this study

Official title: Phase 1 Novel Topical Treatment for Post-herpetic Neuralgia

Shingles is an outbreak of rash or blisters on the skin that is caused by the same virus that causes chicken pox. Some people experience continued pain even after the shingles rash and blisters have healed; this pain is known as postherpetic neuralgia. The purpose of this study is to evaluate the effectiveness of a new topical treatment for postherpetic neuralgia in adults.

Read the detailed description

After an initial infection of chicken pox, the varicella-zoster virus can remain dormant inside nerve cells. Years later, the virus can be reactivated, causing a repeat outbreak called shingles. The first symptom of shingles is usually a burning or tingling pain in one particular location and on one side of the body. This pain can range from mild to severe. Other possible symptoms of shingles include numbness and itching. After several days or 1 week, a rash of fluid-filled blisters similar to chicken pox appears. For most healthy people, a case of shingles heals within a month. However, some people continue to feel pain after the rash and blisters have resolved; this pain is known as postherpetic neuralgia. Current treatments for postherpetic neuralgia include antiviral drugs, steroids, antidepressants, anticonvulsants, and topical products. A new topical treatment consists of a liquid product that is applied directly to the skin to let dry and form a thin, transparent barrier film. In contrast to creams or ointments that can stay in contact with skin for only minutes, this product remains intact on the skin for many hours, providing sustained delivery of a drug or medication while maintaining barrier protection for the skin. The purpose of this study is to evaluate the effectiveness of this new topical treatment for postherpetic neuralgia in adults.

This study will last about 3 weeks and will include seven study visits on Days 1, 8, 9, 15, 16, 22, and 23. All study visits will include questionnaires on pain levels and an examination and digital photos of the affected skin area. The study visit on Day 1 will also include a urine pregnancy test and a review of medical and medication history. During the study visits on Days 8, 15, and 22, one of three topical products will be applied to participants' affected skin. The product will dry on the skin in 30 to 45 seconds. Participants will then wait at the study site for 1.5 hours, after which they will record the time when they experienced pain relief. At each of these three treatment visits, participants will receive one of the following three topical products: Epikeia coatings with aspirin, Epikeia coatings with local anesthetic, and Epikeia coatings alone. At these three study visits, questionnaires, examinations, and digital photographs will occur both before and after the products are applied to the skin. Throughout the study, participants will record their pain levels and medications in a diary, which will be reviewed at all study visits.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Epikeia coatings with aspirin, Epikeia coatings with lidocaine and Epikeia coatings alone in people with Postherpetic Neuralgia, run by Biomedical Development Corporation at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Latency to analgesia onset and duration of analgesia measures (time frame: Between 8 and 16 hours after treatment application). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2011; AzTrials last refreshed its copy on 6 Nov 2026.
