Bimatoprost 0.03% Solution With NB-UVB Versus Their Use With Fractional Carbon Dioxide Laser in Treatment of Generalized Vitiligo
A Phase 4 study testing Bimatoprost 0.03% ophthalmic solution in people with Generalized Vitiligo, run by Assiut University.
Trial summary
Vitiligo is a chronic disorder of pigmentation characterized by the development of white macules on the skin due to loss of epidermal melanocytes. It affects approximately 0.5%-2% of general population world-wide, without predilection for sex or race.Vitiligo can be classified into segmental or non-segmental. Read more about this study

About this study
Official title: Bimatoprost 0.03% Solution, NB-UVB and Fractional Carbon Dioxide Laser in Treatment of Generalized Vitiligo
Vitiligo is a chronic disorder of pigmentation characterized by the development of white macules on the skin due to loss of epidermal melanocytes. It affects approximately 0.5%-2% of general population world-wide, without predilection for sex or race.Vitiligo can be classified into segmental or non-segmental. Non-segmental or generalized vitiligo is the most common clinical presentation and often involves the face and acral regions.
Multiple monotherapy modalities are established to treat vitiligo but the response is variable, unsatisfactory, and requiring a prolonged course. This problem is exaggerated by the multifactorial and polygenic nature of the pathomechanism of the disease. These facts pave the way to combination therapy that showed better and safe repigmentation response than monotherapy.
Read the detailed description
Bimatoprost 0.03% ophthalmic solution is a synthetic prostaglandin F2 alpha analog that is approved for the treatment of glaucoma and eyelashes hypotrichosis (Lee et al, 2017). Cutaneous hyperpigmentation of the treated sites has been reported as a side effect with this agent. Phototherapy (narrow band ultraviolet B (NB-UVB)) of wavelength 308 nm, is considered as a successful method of treatment of vitiligo. The cytotoxic T-cells accountable for the destruction of melanocytes and disappearance of melanin are eliminated by phototherapy through apoptosis (diffuse repigmentation) and UVB does stimulate melanocytic proliferation and their migration to the epidermis from nearby follicular units (follicular repigmentation) and perilesional active melanocytes (marginal repigmentation).
In recent years, fractional carbon dioxide laser has been introduced as an add-on treatment for vitiligo. It represents a new modality for skin resurfacing based on the theory of fractional photothermolysis. The beneficial effect of fractional carbon dioxide laser on vitiligo is the release of cytokines and growth factors that act as mitogens for melanogenesis. It also alters the skin barrier, which results in increased penetration of topical drugs and ultraviolet (UV) radiation, so it can be used in combination therapy.

Each patient will be subjected to the following:
One side will be treated by narrow band ultraviolet rays B sessions twice weekly for 3 months + topical bimatoprost 0.03% solution twice daily ( 1 drop for each 2 cm2 ) and the other side will be treated by topical bimatoprost 0.03% twice daily ( 1 drop for each 2 cm2 ) + narrow band ultraviolet rays B sessions twice weekly for 3 months + 10.600-nm fractional carbon dioxide laser sessions twice monthly for 3 months.
Patients' Evaluation:
The recruited patients will be subjected to:
- Full history taking. B) General clinical examination. C) Dermatological examination of the skin lesions. D) Vitiligo area scoring index score will be calculated for each patient E) Clinical photographs will be taken at baseline, after each month during treatment and after the end of treatment by 3 months.
- A skin biopsy from the treated lesions for histochemical examination. F) Dermoscopic evaluation of the treated sites every 2 weeks.

What is being measured
The primary outcome is the main question the study is designed to answer.
Repigmentation of skin lesions
Patients will be followed up by two blind dermatologists after 3 months to detect:
The percent of repigmentation: that will be subjectively rated with a previously reported scoring system:
- < 25% repigmentation (poor).
- 25-50% repigmentation (fair).
- 50-75% repigmentation (good). -> 75% repigmentation (excellent).
Measured: 3 months
Frequency and types of side effects
Frequency and types of side effects.
Measured: 3 months
Secondary outcomes (2)
Vitiligo area scoring index score
Vitiligo area scoring index score percent change will be calculated by subtracting the pre- procedure vitiligo area scoring index score from the post-procedure vitiligo area scoring index score and dividing by the pre-procedure vitiligo area scoring index score.
Measured: 3 months
Patient satisfaction
The patient overall satisfaction will be assessed after 6 months according to Wong Overall satisfaction:
- dissatisfied
- neutral
- somewhat satisfied
- moderately satisfied
- very satisfied
Measured: 6 months

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Bimatoprost 0.03% ophthalmic solution in people with Generalized Vitiligo, run by Assiut University.
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 6 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 3 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.
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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Amira Abdel-Motaleb (01005263721, Amiraali21@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Repigmentation of skin lesions (time frame: 3 months). The study lists 2 primary outcomes in all. 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 NCT03487042, which also lists 9 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 3 Apr 2018.
