About this study

Hereditary epidermolysis bullosa (HEB) is a heterogeneous group of rare genetic diseases, characterized by fragility of the skin and mucous membranes, which results in the appearance of mucocutaneous bullae and erosions during minimal trauma. Pruritus is a neuropathic pain mainly related to activation of unmyelinated cutaneous C nerve fibers and is very common in patients with HEB. It is the cause of trophic disorders, aggravation of certain wounds, appearance of new bubbles. In addition, this chronic pruritus can also have a major psychological impact on the patient and his family. However, these therapies used in the pruritus of patients with HEB have often proven to be ineffective.

In order to improve the quality of life of children and their families, research into new therapies to limit this chronic pruritus is necessary. Among phytocannabinoids, CANNABIDIOL (CBD) should be clearly distinguished from Delta-9-tetrahydrocannabinol (THC). Indeed, CBD is an "inverse" agonist of the CB2 receptor, it acts by reducing the effect of this receptor, while THC is an agonist of the CB1 and CB2 receptors. Thus, CBD has antipsychotic, anxiolytic, antiemetic, anti-inflammatory and anti-epileptic effects, unlike THC which has psychotic, relaxation effects, impairs cognitive function and memory. Cannabinoids are involved in the physiopathology in pruritus at the level of the peripheral nervous system via the CB1 and TRPV1 receptors, and also at the level of the central nervous system thanks to the CB1 and CB2 receptors. In addition, inflammation plays an important role in the physiopathology of pruritus and this is reduced via the activation of CB2 receptors, expressed in immune cells. Various studies with promising results have examined the effect of cannabinoids in pruritus. No serious adverse effects have been reported and the rare adverse effects that have been observed are reversible upon discontinuation of treatment.

The research project seeks to estimate the efficacy of CANNABIDIOL in the pruritus of 10 children with severe hereditary epidermolysis bullosa. Pruritus is assessed before the start of treatment, then after one month of taking oral treatment, three times a day. The effectiveness of taking the treatment will also be assessed on pain, on the impact on sleep and on overall quality of life. The tolerance of CANNABIDIOL will be well monitored. The systemic passage of CANNABIDIOL is measured during a routine blood test 1 month after treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cannabidiol in people with Hereditary Epidermolysis Bullosa, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 7 inclusion and 10 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 5 Mar 2026. 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 France. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Clinically significant decrease of pruritus Visual Analog Scale (VAS) scores (time frame: Day 30). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05651607, which also lists 11 linked publications.

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 5 Mar 2026.
