Brief summary
The study is focused to prove that the efficacy of a 1% Bifonazole cream is superior to a placebo cream after non-surgical nail ablation with a 40% urea paste.
Interventions
1 squeeze of Bifonazole cream sufficient to cover the infected nail bed(s) with a thin layer once daily for 28 days after nail ablation with urea paste
1 squeeze of Placebo cream sufficient to cover the infected nail bed(s) with a thin layer once daily for 28 days after nail ablation with urea paste

Inclusion criteria
* Age of at least 18 years; * Positive clinical findings of onychomycosis according to the judgement of the investigator (e.g. thickening, discoloration, structural changes, misshaped nails); * Positive mycological findings (positive microscopy and positive culture with identification of pathogen) in material taken from affected nail sites before the start of treatment; * Nail mycosis with an affected nail area between 20% and 50% in the target nail, * Nail mycosis in not more than 3 nails (each nail not more than 50% infected area)
Exclusion criteria
