Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
micro-needling is a procedure used to stimulate collagen synthesis. It consists of a handheld device with protruding fine needles which pentrate the skin inducing regeneration. Selected wounds will have the microneedling device. This occurs once during the study at baseline. Similar symmetrical wounds will be chosen. One of the pair will be randomised to have the active treatment (microneedling), the other will have the placebo (microneedling device without needles). This will occur at baseline and then both wounds will be measured to determine which heals faster. This is not a cross-over trial.

Eligibility

Diagnosis of RDEB-HS (patients should have detectable low levels of collagen VII expression and reduced / abnormal anchoring fibrils on electron microscopy).
At least 2 symmetric wounds on each side of the body (arms, chest/abdomen, legs) of approximately the same size (at least 4 cm2 as measured accurately by the Visitrak wound measurement system [Smith & Nephew Healthcare Ltd., Hull], difference should not be more than 15%).
Ability to sign informed consent, which indicates the investigational nature of this study.
Age greater than or equal to 18.
Minimum age
18 Years
Maximum age
No limit
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Clinical evidence of local infection of the targeted wound(s).
Histopathologic evidence of malignancy (i.e. squamous cell carcinoma - SCC) of the targeted wound(s).
Use of systemic or topical steroid therapy within 30 days before enrolment.
Use of any investigational drug within the 30 days before enrolment.
Patients considered by the investigators to be unreliable or have poor compliance
Patients who are pregnant, or who suspect they may be pregnant at the time of the study and lactating women. Women of childbearing age should use effective contraception.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients with a diagnosis of RDEB-HS will be recruited for the study. This study will be offered to patients who fulfil the inclusion criteria regardless of gender, race or ethnicity. For each enrolled patient, two to eight symmetric wounds on each side of the body (arms, chest/abdomen, legs) of approximately the same size (at least 4 cm2 as measured accurately by the Visitrak wound measurement system [Smith & Nephew Healthcare Ltd., Hull], difference should not be more than 15%) will be identified by a study dermatologist. These symmetrical wounds will be randomised to either treatment or placebo. 'Allocation is not concealed'
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
the clinical trials pharmacist will use randomisation codes to determine the randomisation process and sequence for the wounds as to which receives treatment or placebo.
Masking / blinding
