About this study

Official title: Optimizing the Treatment of Toenail Onychomycosis Using a New Transdermal Patch Combined With Terbinafine and Ketoconazole Formulation

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.

Read the detailed description

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. At least 18 patients (age: 20 to 75 years old) with one or two feet toenails infected simultaneously need to complete the whole study. Patients will be assigned to one of patch groups. The patients with only one infected toenail will also apply one patch on other foot with uninfected toenail. The patch will be applied on the foot on the dorsal site and leave it there for two consecutive days. Totally six patches will be used for each week. The duration of therapy will be 24 weeks. The patients' blood sample and toenail clippings will be collected every 8 weeks and will be analyzed as well as the safety profiles. The most appropriate patch formulation will be selected on the drug content residues in toenail. The safety profile will be also presented and discussed with various anti-onychomycosis patch formulations.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 3 mg terbinafine and 2 mg ketoconazole containing patchDrug

    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.

  • 6 mg terbinafine and 2 mg ketoconazole containing patchDrug

    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.

  • 8 mg terbinafine and 2 mg ketoconazole containing patchDrug

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

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

Secondary outcomes (2)
  1. (1) Efficacy is evaluated 24 weeks after the start of treatment and will be recorded at baseline, 8-week, 16-week and 24-week.

    The degrees of improvement are assessed based on each toenail as follows:

    1. Complete cure is defined as regeneration of a healthy nail plate to replace the diseased nail.
    2. Marked improvement is defined as regeneration of a healthy nail plate in at least 70% of the affected nail.
    3. Improvement is defined as regeneration in 40-70% of the affected nail.
    4. Slight improvement is defined as regeneration in less than 40%.
    5. No change is defined as the absence of change or exacerbation of the disease condition or the side effect.

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

  2. (2) Safety Monitoring

    Adverse events, both local and systemic, will be recorded and their relation to the trial drugs is judged.

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

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 3 mg terbinafine and 2 mg ketoconazole containing patch, 6 mg terbinafine and 2 mg ketoconazole containing patch and 8 mg terbinafine and 2 mg ketoconazole containing patch in people with Onychomycosis, run by Taiwan Biotech Co., Ltd. at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Mei-Fang Wen (886-2-2737-2181 ext. 3925, 985146@h.tmu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Presented by pharmacokinetic data (drug plasma concentrations vs. time) or drug deposit amounts in feet nails. (time frame: baseline, 8-week, 16-week and 24-week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jun 2012.
