About this study

Official title: A Phase III Randomized, Evaluator-Blind, Parallel Group Study of the Safety and Efficacy of Itraconazole Tablets, Itraconazole Capsules and Placebo in the Treatment of Onychomycosis of the Toenail.

Onychomycosis is a common condition accounting for approximately half of all nail disorders. It is most commonly caused by dermatophytes. Itraconazole has been approved for the treatment of onychomycosis in the United States with an approved dosage regimen for the treatment of onychomycosis of the toenail of once daily (QD) treatment with 200mg of itraconazole (two 100 mg capsules) for 12 weeks. Barrier Therapeutics has developed a 200 mg tablet which could be used in a more convenient one-tablet-per-day dosing regimen. This clinical trial will compare the efficacy and safety of this new tablet formulation with itraconazole capsules and placebo.

Read the detailed description

Onychomycosis is common and accounts for about half of all nail disorders. Usually the cause is due to dermatophytes, either Trichophyton rubrum (71%) or Trichophyton mentagrophytes (20%) but may also be due to yeast infection, usually Candida albicans.

The prevalence of onychomycosis in the United States population as a whole is 13% and is more prevalent in the elderly (60%). Onychomycosis of the toenail recurs and is thought to have a genetic component.

Onychomycosis can result in permanent nail deformity. This disease has a significant impact on the patient's quality of life (e.g., concern with the appearance of the toenails and fingernails, interference with wearing shoes, walking and sports activities).

Itraconazole has been approved for the treatment of onychomycosis in the United States since the mid-nineteen-nineties. The approved dosage regimen for treatment of onychomycosis of the toenail is once daily (QD) treatment with 200 mg of itraconazole (Sporanox®, Janssen Pharmaceutical Products, L.P., Titusville, NJ, USA) for 12 weeks. The approved dosage form is a 100mg capsule. Barrier Therapeutics has developed a 200mg tablet which could be used in a more convenient one-tablet-per-day dosing regimen.

This clinical trial will compare the efficacy and safety of this new tablet formulation with itraconazole capsules and placebo.

What participants receive

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

  • Itraconazole 100mg capsulesDrug

    Also called Sporanox®

    Subjects took two 100mg capsules once per day after a full meal. The dose dose was taken the day before the Week 12 visit.

  • Itraconazole 200mg tabletsDrug

    Also called Onmel

    Subjects took one 200mg tablet once per day after a full meal. The last dose was taken the day before the Week 12 visit.

  • Placebo tabletsDrug

    Also called placebo

    Placebo tablets are the same as the Itraconazole tablets but without the active drug included. Subjects took one tablet once per day after a full meal. The last tablet was taken the day before the Week 12 visit.

What is being measured

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

  1. Clinical and Mycological Cure of Target Toenail

    This study was designed to evaluate the superiority of itraconazole tablets to placebo tablets.

    Clinical Cure was defined as an IGA score of 0 for the target toenail; Mycological Cure was defined as a negative potassium hydroxide (KOH) exam and a negative culture for dermatophytes of the target toenail.

    Measured: 1 year

  2. Complete Cure - Itraconazole Tablets Compared to Itraconazole Capsules

    The primary efficacy endpoint was Compete Cure (consisting of a Clinical Cure and a Mycological Cure) at week 52. In this study, Clinical Cure was defined as an Investigator's Global Assessment (IGA) score of 0 for the target toenail; Mycological Cure was defined as a negative potassium hydroxide (KOH) examination and a negative culture outcome for dermatophytes of the target toenail. The efficacy analyses were conducted to demonstrate the non-inferiority of 1 itraconazole 200-mg tablet to 2 itraconazole 100-mg capsule.

    Measured: 12 months

Secondary outcomes (2)
  1. Clinical Improvement of the Target Toenail

    Clinical Improvement consisted of a mycological cure and an Investigator's Global Assessment (IGA) score less than or equal to 1 at week 52.

    The Investigator's Global Assessment (IGA) assesses the overall severity of onychomycosis on the target toenail and takes into consideration, onycholysis, hyperkeratosis and percent nail involvement.

    0 = Clinical Cure: No evidence of onychomycosis.

    1 = Clinical Improvement: Minimal evidence of onychomycosis. 2 = Mild: ≤25% dystrophy and/or onycholysis. 3 = Moderate: ≤50% dystrophy with onycholysis. 4 = Severe: >50% dystrophy with onycholysis.

    Measured: 12 months

  2. Clinical Improvement Compared to Placebo

    Clinical Improvement consisted of a mycological cure and an Investigator's Global Assessment (IGA) score less than or equal to 1 at week 52.

    The Investigator's Global Assessment(IGA)assesses the overall severity of onychomycosis on the target toenail and takes into consideration, onycholysis, hyperkeratosis and percent nail involvement.

    0 = Clinical Cure: No evidence of onychomycosis.

    1 = Clinical Improvement: Minimal evidence of onychomycosis. 2 = Mild: ≤25% dystrophy and/or onycholysis. 3 = Moderate: ≤50% dystrophy with onycholysis. 4 = Severe: >50% dystrophy with onycholysis.

    Measured: 12 months

A Phase 3 study testing Itraconazole 100mg capsules and Itraconazole 200mg tablets in people with Onychomycosis, run by Stiefel, a GSK Company at 68 sites in 7 countries.

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 6 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: finished, as of the sponsor's last update on 9 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 68 sites in United States, Canada, South Africa, Dominican Republic, Ecuador and 2 more countries. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Jan 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical and Mycological Cure of Target Toenail (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00356915, which also lists 1 linked publication.

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 9 Feb 2017.
