A Phase 3 interventional study of Melanil facial cream and Hydroquinone 2% cream in Melasma, sponsored by Catalysis SL. Completed at 1 site in Cuba. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2012-05-04.
Sponsored by Catalysis SL · Phase 3, Interventional, and Treatment
The purpose of the study is to assess the efficacy of Melanil facial cream in the treatment of melasma. The duration of this double-blind phase 3 clinical trial will be 54 weeks. The control group will receive treatment with Hydroquinone (2%). The estimated number of subjects to be recruited and randomized for the study is 150. The primary outcome measure: Melasma Area and Severity Index (MASI) score will be assessed at the beginning of the study and at weeks 4, 8, 12 and 54. Photographs taken at the beginning of the study and at weeks 8, 12 and 54 will be evaluated by two independent dermatologists. Occurrence of adverse effects will also be assessed.
170 studies on the registry are indexed under Melanosis; 46 are open to participants now.
This study's enrollment of 150 is above the median of 40 across 157 interventional studies indexed under Melanosis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
