Plain English summary of protocol

Background and study aims
Vitiligo, a skin disorder characterized by the loss of pigment, can significantly impact the affected individual's mental well-being, social interactions, and quality of life due to its visible nature and associated stigma. This study involves a new topical skin treatment called VIM-004 Gel, which combines afamelanotide, a known medication that increases the pigmentation of the skin with STAR particles, a medical device used for creating micropores across the top layers of the skin to allow the delivery of afamelanotide, that otherwise would not penetrate the skin. VIM-004 Gel aims to help repigment the skin areas affected by vitiligo.

Who can participate?
Adult patients aged between 18-70 years old with vitiligo

What does the study involve?
Participants must pass a clinical evaluation including lab tests and a physical examination to confirm eligibility to participate. Two skin areas affected by vitiligo will be selected for each participant. Except for the areas located in the face, these areas should include between 10-20% of pigmented skin. Participants will receive NB-UVB 3 times/week for 30 days during a pre-treatment phase. The investigational product (VIM-004 Gel) will then be applied to one area 5 times/week for 12 weeks, while a placebo (which is the gel with STAR particles, but without afamelanotide) will be applied to the other. Participants will continue to receive NB-UVB treatment 3 times/week during the treatment phase. Please note that not all areas affected by vitiligo will receive treatment. Participants will be regularly evaluated for safety and tolerability of the drug product, blood samples will be collected periodically and skin images will be collected throughout the treatment period to evaluate response to treatment. Skin biopsies will be performed in a subset of participants.

What are the possible benefits and risks of participating?
Participants may see repigmentation of the treated skin lesion. However, it is not known if taking part in this study will help your condition stay the same or worsen. As part of the study, your health will be closely monitored by qualified doctors. Nevertheless, even if there is no guarantee that you will have a personal medical benefit from taking part in this clinical study, the information obtained may help to better treat people with your condition.

Afamelanotide administered as a subcutaneous implant is associated with plasma exposure and side effects such as nausea, headache, fatigue and hypersensitivity reactions. In addition, systemic exposure to afamelanotide has been shown to induce skin hyperpigmentation of non-lesional skin in vitiligo patients. In this study, VIM-004 Gel will be applied on restricted areas of the skin, so the amount of the active ingredient expected to reach the bloodstream is anticipated to be minimal, and the blood levels at which these side effects occur are unlikely to be reached. You may experience an increase in pigmentation in the application area. In addition, when applied on the skin, there is a possible risk of local skin reactions, including erythema, oedema, and/or bleeding, associated with the mechanical mode of action of the STAR particles. When VIM-004 Gel is applied on the face there is a potential risk of translocation of STAR particles to the eyes and the mouth. There may be side effects from the investigational product that are not known at this time.

Where is the study run from?
The study is being conducted by Centre International de Développement Pharmaceutique, Mauritius

When is the study starting and how long is it expected to run for?

Health condition(s) or problem(s) studiedVitiligo
InterventionAll eligible participants will be randomized using the randomization list provided by an unblinded statistician. The randomization list will define the treatment (VIM-004 Gel or VIM-004 Placebo Gel) to be allocated to each treatment area (Area 1 and Area 2) per participant (intra-individually). The pre-defined list will ensure that treatment assignment is unbiased, and this will be concealed from participants and blinded site staff. The randomization schedule will be produced by the unblinded staff using SAS 9.4. The unblinded statistician will not take part in any of the study-related processes.

Two application areas between 9-25 cm2 will be defined. Participants will start with a narrow-band (NB)-UVB pretreatment period for 30 days in all application areas. These areas will be randomised in a 1:1 ratio on Day 1 to VIM-004 Gel and VIM-004 Placebo Gel, with NB-UVB treatment. VIM-004 Gel or VIM-004 Placebo Gel will be applied topically once a day on the 2 application areas. The application will be repeated for a total of 5 consecutive days per week for 12 weeks. During the treatment period, all application areas will also receive NB-UVB treatment 3 times per week. There will be a 4-week follow-up period.
