Bifonazole cream 1%

Drug

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

placebo cream

Drug

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

Primary outcomes

  3. Microscopy negative

    Time frame: 14 days, 3 and 6 months after end of treatment (=visit 3, 4, and 5)

  4. Relapse rate (overall cure at visit 3 but positive clinical or mycological findings at visit 4

    Time frame: 3 and 6 months after end of treatment (=visit 4 and 5)

  5. Mycological cure rate (microscopy + culture negative)

    Time frame: 3 and 6 months after end of treatment (=visit 4 and 5)

  6. Culture negative

    Time frame: 6 months after end of treatment (=visit 5)
