The efficacy and safety of ENRICHED (X92001591) will be evaluated in a multicentric, randomized, evaluator blinded clinical investigation in 88 patients.

Subjects will be treated with either the test medical device (ENRICHED X92001591) or the reference product (Loceryl, 5% amorolfine) for a period of 9 months. The primary objective of the investigation will be increase of % of healthy nail surface versus baseline, as evaluated by a blinded investigator. Subjects will be followed up for a period of 9 months, with visits at D0 (baseline), D90 (month 3), D180 (month 6) and D270 (month 9).

Inclusion Criteria:

• 1. Patient having given freely her/his informed, written consent. 2. Patient having a good general health. 3. Age: between 18 and 70 years; 4. Patient with superficial onychomycosis on at least one great toenail or fingernail (for at least 10% in each arm) or light to moderate disto-lateral onychomycosis (without matrix involvement and involvement <2/3 of the tablets).

  5. Patient with positive KOH staining. 6. Patient cooperative and aware of the products modalities of use and the necessity and duration of the controls so that perfect adhesion to the protocol can be expected.

  7. Patient being psychologically able to understand information and to give their/his/her consent.

  8. Patient having stopped any systemic antifungal treatment since at least 6 months before screening and/or any topical antifungal treatment since at least 3 months before screening.

  9. Patient who agree to refrain from receiving pedicure/manicure, artificial nails and/or cosmetic nail varnish or other medication on the nail being treated for the entire study duration.

The primary objective is to evaluate the effectiveness of Enriched and Loceryl® in the treatment of onychomycosis based on the blinded evaluation of the percentage of healthy nail surface compared to baseline
