About this study

The purpose of this study is to investigate the efficacy and safety of autologous transplantation of melanocytes in patients with vitiligo.

Read the detailed description

Vitiligo is a pigmentation disorder in which white patches of skin appear on different parts of the body. Histologically it is characterized by absence of melanocytes along the epidermal basal layer.

Using cell suspension with non-cultured melanocytes which injected into blister of depigmented lesion, a success rate of 85% was reported for repigmentation. However there are some limitations in this technique: the induction of blister is limited to several sites of the body, hypo-pigmentation around the recipient area due to cryodamage of peripheral melanocytes and leakage of suspension out of the blister. To reduce these problems, in this study we will inject melanocytes directly to epidermis.

A shaved biopsy specimen (about 1 cm2) is taken from the patient's normally pigmented area under local anesthesia (lidocaine hydrochloride 20 mg/ml). The specimens are incubated in 0.25% trypsin solution for 15 minutes at 37°C 0.02% EDTA solution for 10 minutes. Then epidermal sheets are gently manipulated with forceps to dissociate the epidermal cells and to yield a cell suspension, followed by treatment with 0.5% trypsin/versene solution at 37C for 3-5 minutes. Well-dispersed cell suspension is aspirated into 1 ml syringes and injected directly in epidermis.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Melanocyte transplantation in people with Vitiligo, run by Royan Institute at 1 site in Iran.

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 5 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 20 Jul 2016. 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 Iran. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

percentage of repigmentation (time frame: 2 and 4 weeks after transplantation). 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 NCT00631865, which also lists 1 linked publication.

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 20 Jul 2016.
