Inclusion criteria

  • Subject having given her/his informed, written consent,
  • Subject cooperative and aware of the modalities of use and the necessity and duration of the controls so that perfect adhesion to the protocol can be expected.
  • Subject being psychologically able to understand information and to give their/his/her consent.
  • Age: more than 18 years.
  • Subject with superficial onychomycosis on at least one great toenail or light to moderate disto-lateral onychomycosis (without matrix involvement and involvement \<2/3 of the tablet).
  • Subject with positive results of KOH staining.
  • Subject having stopped any systemic antifungal treatment since at least 6 months before inclusion and/or any topical antifungal treatment since at least 3 months before inclusion.
  • Female subjects of should use an accepted regimen since at least 12 weeks before the beginning of the study, during all the study and at least 1 month after the study end.

Exclusion criteria

Exclusion Criteria:

  • Subject considered by the Investigator likely to be non-compliant with the protocol.
  • Patient enrolled in another clinical trial during the test period.
  • Woman being pregnant, nursing or planning a pregnancy during the course of this study.
  • Subject having a known allergy to one of the constituents of the tested products.
  • Patient suffering from serious or progressive diseases (to investigator's discretion), such as diabetes, peripheral circulatory disease, , psoriasis, lichen planus, pathology....
  • Subject with cutaneous pathology on studied zone (other than onychomycosis like angioma, dermatitis...).
Terms in these criteria, in plain language(4)

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

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.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. At the end of the study (day 168), evolution of the percentage of healthy surface versus baseline, was evaluated by a blinded investigator. Comparison with the comparator product.

    Percentage healthy surface was assessed using digital image analysis. Briefly, two macro-photographs (top and front) were made of the great toenail, placed beside a piece of graph paper to allow determination of the exact size of the nail during analysis (contour tracing). Consequently, all pictures were digitalised and recorded on the computer. Image analysis of the top picture was performed with Adobe Photoshop software. For each photograph, a blinded dermatologist traced the healthy surface.

    Time frame: After 168 days of treatment

Secondary outcomes

  1. At different time points, evolution of the percentage of healthy surface versus baseline, was evaluated by a blinded investigator. Comparison with the comparator product.

    Percentage healthy surface was assessed using digital image analysis. Briefly, two macro-photographs (top and front) were made of the great toenail, placed beside a piece of graph paper to allow determination of the exact size of the nail during analysis (contour tracing). Consequently, all pictures were digitalised and recorded on the computer. Image analysis of the top picture was performed with Adobe Photoshop software. For each photograph, a blinded dermatologist traced the healthy surface.

    Time frame: After 14, 28, 56 and 112 days of treatment

  2. Evaluation of the clinical efficacy assessed by the investigator with structured scales. Comparison with the comparator product.

    Onycholysis, nail dystrophy, nail discoloration and nail thickening were assessed using the following scores: 0 = none, 1 = very slight, 2 = slight, 3 =moderate, and 4 = severe.

    Time frame: On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168

  3. Evaluation of the microbiological efficacy of the product assessed by fungal culture and comparison with the comparator product.

    Time frame: On baseline (day zero) and day 168

  4. Evaluation of the product tolerance, assessed by the investigator by clinical evaluation and subject interrogatory with a score from 0 (bad tolerance) to 3 (very good tolerance).

    Time frame: After 14, 28, 56 and 112 days of treatment

  5. Evaluation of the quality of life of the subjects thanks to the questionnaire NailQoL . Comparison with the comparator product.

    Time frame: On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168

  6. Subjective evaluation by subjects by completing the subjective evaluation questionnaire at each visit.

    Time frame: On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 21, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
