NCT01615913

Brief Summary

This study is to explore the optimization of anti-onychomycosis patch with various formulation contents (three patch groups: 3%, 6% and 8% of terbinafine (contains 3-mg, 6-mg and 8-mg/patch terbinafine, respectively) combined with fixed 2% ketoconazole (contains 2-mg ketoconazole/patch) and its safety profile.

Outcome Measures

Primary Outcomes (1)

  • Presented by pharmacokinetic data (drug plasma concentrations vs. time) or drug deposit amounts in feet nails.

    Both terbinafine and ketoconazole plasma concentration, and their residual contents in toenails will be measured with a validated LC/MS-MS method.

    baseline, 8-week, 16-week and 24-week

Secondary Outcomes (2)

  • (1) Efficacy is evaluated 24 weeks after the start of treatment and will be recorded at baseline, 8-week, 16-week and 24-week.

    baseline, 8-week, 16-week and 24-week

  • (2) Safety Monitoring

    baseline, 8-week, 16-week and 24-week

Study Arms (3)

3% terbinafine patch

EXPERIMENTAL

A 10-cm2 patch containing 3 mg terbinafine and 2 mg ketoconazole

Drug: 3 mg terbinafine and 2 mg ketoconazole containing patch

6% terbinafine patch

EXPERIMENTAL

A 10-cm2 patch containing 6 mg terbinafine and 2 mg ketoconazole

Drug: 6 mg terbinafine and 2 mg ketoconazole containing patch

8% terbinafine patch

EXPERIMENTAL

A 10-cm2 patch containing 8 mg terbinafine and 2 mg ketoconazole

Drug: 8 mg terbinafine and 2 mg ketoconazole containing patch

Interventions

A novel transdermal patch that is to be used to treat toenail onychomycosis with minimal body exposure to the antifungal drugs. The active substances in the patch are 3% terbinafine (contains 3-mg terbinafine/patch) and 2% ketoconazole (contains 2-mg ketoconazole/patch). The average daily released drug amount estimated from in-vitro skin permeation test were about 3.99 mcg for terbinafine and 1.70 mcg for ketoconazole, respectively.

3% terbinafine patch

A novel transdermal patch that is to be used to treat toenail onychomycosis with minimal body exposure to the antifungal drugs. The active substances in the patch are 6% terbinafine (contains 6-mg terbinafine/patch) and 2% ketoconazole (contains 2-mg ketoconazole/patch). The average daily released drug amount estimated from in-vitro skin permeation test were about 8.52 mcg for terbinafine and 2.03 mcg for ketoconazole, respectively.

6% terbinafine patch

A novel transdermal patch that is to be used to treat toenail onychomycosis with minimal body exposure to the antifungal drugs. The active substances in the patch are 8% terbinafine (contains 8-mg terbinafine/patch) and 2% ketoconazole (contains 2-mg ketoconazole/patch). The average daily released drug amount estimated from in-vitro skin permeation test were about 10.7 mcg for terbinafine and 2.17 mcg for ketoconazole, respectively.

Eligibility Criteria

Age25 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male and females 20-75 years of age
  • Fungal infection of one or both toenails will be confirmed using the method of histopathological examination with periodic acid-Schiff (PAS) staining (Yang JH, et al., 2007)
  • The toenail infection can be due to a dermatophyte, yeast or mixed infections (dermatophyte and non-dermatophyte)
  • The target toenail area must have at least 25% to no more than 75% disease involvement without spikes
  • Patients agree to sign the informed consent form

You may not qualify if:

  • Using any kind of systemic or topical nail lacquer solution antifungal drugs within 6 months before at screening visit; or using any other topical antifungal agents, such as ointment, cream, gel, solution, suspension, oil or lotion forms, within two weeks before at screening visits
  • Patients with the target toenail involving the matrix (lunula) or having less than 2 mm clear (unaffected) nail plate length beyond the proximal fold
  • Presence of dermatophytoma on the target nail
  • Using professional pedicures or application of any nail polish product or nail cosmetic to the toenails after the screening visit
  • Patients who are unwilling to provide nail clippings
  • Patients who have been previously reported to be allergic to topical or systemic terbinafine or ketoconazole therapy or both
  • Known pregnancy or plan to get pregnant within study duration or lactation at time of enrollment
  • Unconsciousness or inability to understand this form or this study project.
