  Purpose

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.


Condition Intervention Phase
Onychomycosis
Drug: Bifonazole cream 1%
Drug: Placebo cream
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Multicenter, Placebo- Controlled Phase 3 Trial to Prove the Superiority of Bifonazole vs. Placebo After 4 Weeks of Onychomycosis Treatment/ as a Follow-up of a 2 Weeks Treatment of Non-surgical Nail Ablation of Diseased Nail Matrix With 40% Urea Paste

Primary Outcome Measures:
  • Overall cure rate comprising clinical cure and mycological cure microscopy + culture negative [ Time Frame: 14 days after end of treatment (=visit 3) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Clinical cure rate [ Time Frame: 14 days, 3 and 6 months after end of treatment (=visit 3, 4, and 5) ] [ Designated as safety issue: No ]
  • Culture negative [ Time Frame: 14 days, 3 and 6 months after end of treatment (=visit 3, 4, and 5) ] [ Designated as safety issue: No ]
  • Microscopy negative [ Time Frame: 14 days, 3 and 6 months after end of treatment (=visit 3, 4, and 5) ] [ Designated as safety issue: No ]
  • 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) ] [ Designated as safety issue: No ]
  • Mycological cure rate (microscopy + culture negative) [ Time Frame: 3 and 6 months after end of treatment (=visit 4 and 5) ] [ Designated as safety issue: No ]
  • Culture negative [ Time Frame: 6 months after end of treatment (=visit 5) ] [ Designated as safety issue: No ]
  • Incidence of adverse events [ Time Frame: 2 weeks, 3 and 6 months after end of treatment (=visit 3, 4, and 5) ] [ Designated as safety issue: Yes ]
