Intervention / Behandlung

Detaillierte Beschreibung

Patients with a positive dermatophyte/fungal culture from a toenail sample are eligible for inclusion in the study. Patients apply the device under investigation daily to the affected toenails.

Patients are followed for up to 6 months, or until a negative fungal culture is obtained and the clinical appearance of the treated nails indicates resolution and significant improvement of the onychomycosis.

Four visits will be organized at the investigation site under the supervision of the principal investigator:

  • Baseline / Inclusion visit (V0)
  • 3 follow-up visits (V1, V2 and final V3) carried out 1, 3 and 6 months after the initiation of the treatment.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Mycological cure rate evaluated at 6 months
Zeitfenster: 180 days

Mycological cure is defined by a negative culture for dermatophytes/fungi from the big toenail under study.

A direct microscopic examination is performed after dissolving and staining the toenail sample using MYCETCOLOR® (Mycol60). The potassium hydroxide (KOH) test indicates the presence or absence of fungal elements. However, it does not provide information on the viability or etiology of any fungal elements detected.

Therefore, the samples are also placed on a suitable culture medium and incubated at a controlled temperature for several days to several weeks. Fungal growth is monitored, and any colonies that appear are identified microscopically to determine the specific fungal species involved.

Change from baseline in onychomycosis severity at 1 month
Zeitfenster: 30 days

The severity of onychomycosis, assessed by a trained investigator, and using the global score of Onychomycosis Severity Index or OSI.

It provides a numerical score ranging from 0 (normal nail) to 35 (total dystrophy with full matrix involvement), based on three components:

  • Nail Involvement Area (1-5 points): percentage of the nail plate affected by onychomycosis estimated visually (0, [1-10], [11-25], [26-50], [51-75], [76-100]) and translated into a score;
  • Disease proximity to matrix from distal edge (<1/4, [1/4 to 1/2], [1/2 to 3/4], >3/4). The area score is then multiplied based on the location of the infection (x1 if the involvement is distal and/or lateral only; x2 if the involvement extends proximally and/or reaches the nail matrix);
  • Additional Points for Nail Features: +10 points if presence of hyperkeratosis ≥2 mm or dermatophytoma (i.e., longitudinal streak or patch).

Improvement in quality of life at 6 months
Zeitfenster: 180 days

Quality of life is assessed using a questionnaire composed of the following three scales:

Nail Distress Scale: Subjects indicate how often they experience nail-related distress during the past week using a 5-point scale (4 = strongly disagree; 3 = disagree; 2 = neither agree nor disagree; 1 = agree; 0 = strongly agree).

Nail Symptoms Scale: Subjects indicate how concerned they have been about their nail condition during the past week using a 5-point scale (4 = not at all; 3 = a little; 2 = somewhat; 1 = very; 0 = extremely).

Physical Scale: Subjects indicate how their nail condition interferes with their activities during the past week using a 5-point scale (4 = never; 3 = rarely; 2 = sometimes; 1 = often; 0 = always).

The raw scores each scale are added together to produce a total raw score which is converted to a score ranging from 0 (worst) to 100 (best), with higher scores indicating better outcomes.
