Completed
Conditions
Onychomycosis
Interventions
Drug: terbinafine
Drug: Placebo
Registration Number
NCT00443898
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

This study is designed to assess the efficacy, safety and tolerability of a topical formulation of terbinafine solution applied daily in patients with toenail fungus.

Exclusion Criteria
  • Target foot must not have severe plantar (moccasin) tinea pedis that would require systemic therapy. Mild to moderate tinea pedis (athlete's foot) infection should be treated with terbinifine prior to baseline or at any time during the trial. Other topical treatments for athlete's foot may be recommended at the discretion of the investigator.
  • Subjects must not have abnormalities of the nail that could prevent a normal appearing nail if clearing of infection is achieved
  • No administration of systemic antifungal medications within 6 months prior to screening visit
  • No application of prescription topical antifungal medications for toenail fungus within 3 months or other commercially available topical medications for toenail fungus applied directly to the toenails within 1 month prior to screening visit
  • No professional pedicures or application of any nail polish product or nail cosmetic to the toenails after the screening visit
  • Known pregnancy or lactation at time of enrollment

Primary Outcome Measures
NameTimeMethod
Efficacy Assessed by Complete Cure Rate at the End of Study (Week 52) After Treating for 24 or 48 Weeks.52 weeks

Complete cure is defined as negative KOH microscopy and negative culture for dermatophytes.

and no residual involvement of the target toenail. The complete cure was a composite binary variable defined as "Yes" if:

* Mycological cure (negative KOH and negative culture for dermatophytes) and

* No residual involvement of the target toenail "No" if otherwise

Secondary Outcome Measures
NameTimeMethod
Efficacy Assessed by Mycological Cure (Negative Culture and Negative KOH Microscopy) at the End of Study After Treating Patients for 24 or 48 Weeks.52 weeks

Mycological cure is defined as negative KOH microscopy and negative culture for dermatophytes.

Mycological cure was a composite binary variable defined as "Yes"if :

* Negative microscopy and

* Negative culture for dermatophytes "No" if otherwise.

Efficacy Assessed by Clinical Efficacy at the End of Study After Treating Patients for 24 or 48 Weeks.52 weeks

Clinical effectiveness is defined as negative KOH microscopy and negative culture for dermatophytes and \<= 10% residual involvement of the target toenail.

Clinical effectiveness was a composite binary variable defined as "Yes" if

* Mycological cure (negative KOH and negative culture for dermatophytes) and

* = 10% residual involvement of the target toenail "No" if otherwise

Number of Participants Assessed With Adverse Events and Serious Adverse Events52 weeks

An adverse event (AE) is any adverse change in health or side effect that occurs while the participant is receiving the treatment or within a previously specified period of time after the treatment has been completed.

A Serious Adverse Event (SAE) is any untoward medical occurrence that results in death, is life-threatening requires, inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or requires intervention to prevent permanent impairment or damage.
