Overview
Brief Summary
The purpose of this research study is to gather information on the effectiveness and tolerability of a novel composition of existing U.S. Food and Drug Administration (FDA) approved topical medications for the treatment of moderate to severe melasma.
Detailed Description
Subjects with moderate to severe melasma will apply 0.5 grams (pea-sized) amount of Illuminate Cream topically to affected areas for 20 weeks. The change in Melasma Area and Severity Index (MASI) score will be evaluated a baseline and Weeks 4, 12, and 20. The MASI score is a validated test, calculated by subjective assessment of 3 factors: Area (A) of involvement, Darkness (D), and Homogeneity (H), with the forehead, right malar region, left malar region, and chin, corresponding to 30%, 30%, 30% and 10% of the total face, respectively. The area of involvement in each of these 4 areas is given a numeric value of 0 to 6 (0 = no involvement; 1 = \<10%; 2 = 10%-29%; 3 = 30-49%; 4 = 50-69%; 5 = 70-89%; and 6 = 90-100%). Darkness and homogeneity are rated on a scale from 0 to 4 (0 = absent; 1 = slight; 2 = mild; 3 = marked; and 4 = maximum). The score is calculated by adding the sum of the severity ratings for darkness and homogeneity, multiplied by the value of the area of involvement, for each of the 4 facial areas.

Eligibility Criteria
Inclusion Criteria
- •Informed subject consent will be obtained from those patients meeting the following inclusion criteria:
- •Male and female patients 18 to 65 years age
- •Moderate to severe melasma, as measured by the Melasma Area Severity Index score greater than or equal to 16

Participants must use birth control for the entire study and for at least 1 week after the last application of the study formulation. Acceptable methods of birth control include ongoing hormonal contraception methods, (such as birth control pills, patches, injections, vaginal ring, or implants), barrier methods (such as a condom or diaphragm used with a spermicide), intrauterine devices, tubal ligation, or abstinence
- •Patients who are willing and capable of cooperating to the extent and degree required by the protocol; and
- •Patients who read and sign an approved informed consent for this study
Exclusion Criteria
- •Vulnerable study population
- •Exposure to topical skin-lightening agents within 1 month of study entry, including:
- •Topical corticosteroids
- •Topical bleaching products
- •Topical retinoids
- •Use of systemic preparations within 1 month of study entry, including:
- •Systemic corticosteroids
- •Systemic cyclosporine, interferon
- •Systemic acitretin, etretinate, isotretinoin
- •Systemic methotrexate
Arms & Interventions
Illuminate Cream
Illuminate Cream is a skin-lightening formulation containing multiple drugs, including a retinoid, calcineurin inhibitor, anti-tyrosinase agent and sunscreen microfine zinc oxide. Approximately 0.5 grams to be applied topically to affected areas of skin once per day for 20 weeks.
Intervention: Illuminate Cream
Outcomes
Primary Outcomes
Change in Melasma Area and Severity Index (MASI) Score
Time Frame: Baseline, 20 weeks
Severity of melasma in each of the four regions (forehead, right malar region, left malar region and chin) is assessed on % of the total area involved (A), darkness (D), and homogeneity (H). Scoring for % area involved: 0=none; 1=\<10%; 2=10-29%; 3=30-49%; 4=50-69%; 5=70-89%; and 6=90-100%. Darkness scoring (hyperpigmentation): 0=normal skin; 1=barely visible; 2=mild; 3=moderate; 4=severe. Homogeneity scoring: 0=normal skin color; 1=specks of involvement; 2=small patchy areas of involvement \<1.5 cm diameter; 3=patches of involvement \>2 cm diameter; 4=uniform skin involvement without any clear areas). To calculate the MASI score, the sum of the severity grade for darkness (D) and homogeneity (H) is multiplied by the numerical value of the areas (A) involved and by the percentages of the four facial areas (10-30%). Total MASI score: Forehead 0.3 (D+H)A + right malar 0.3 (D+H)A + left malar 0.3 (D+H)A + chin 0.1 (D+H)A. The total score can range from 0 (normal) to 48 (severe).
Secondary Outcomes
- Change in Melasma Quality of Life Scale (MELASQOL)(baseline, 20 weeks)
- Investigator Assessment of Global Improvement From Baseline(baseline, 20 weeks)
