Scoring Clinical Index For Onychomycosis in Toenail Onychomycosis Treating With Itraconazole Capsules

Phase 4
Completed
Conditions
Onychomycosis, Toe
Interventions
Registration Number
NCT00871728
Lead Sponsor
Janssen Korea, Ltd., Korea
Brief Summary

The purpose of this study is to evaluate the participants with toenail onychomycosis (fungal infection of the nail) confirmed positive by potassium hydroxide (KOH) and bacterial identification test after administration of itraconazole (ICZ) capsule, to identify the change in Scoring Clinical Index for Onychomycosis (SCIO) score and to determine the relationship between the change of SCIO score and mycological cure rate and clinical improvement.

Detailed Description

This is an open-label (all people know the identity of the intervention), multicenter (when more than one hospital or medical school team work on a medical research study) study of ICZ in participants with onychomycosis. The present study consists of 2 periods: Screening period (up to Week minus 2) and Treatment period (up to Week 49). The ICZ will be administered in 3 cycles (Week 1, Week 5 and Week 9) and each cycle will consist of taking 2 capsules of 100 milligram (mg) each, orally, twice daily, continuously for 1 week. Total duration of treatment will be of 49 weeks. Efficacy will primarily be evaluated by percentage of participants showing 10 percent or higher response in SCIO Score. Participants' safety will be monitored throughout the study.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Showing 10 Percent or Higher Response in Scoring Clinical Index for Onychomycosis (SCIO) Score at Week 5Baseline and Week 5

The SCIO is based on clinical state and its items include major factors that can have an effect on the outcome of onychomycosis treatment. The factors include the clinical form, depth of an infected area and subungal hyperkeratosis. The SCIO score range from 1 to 30 and higher score indicates more severity. The score is classified into 7 steps and as there is treatment for each step, treatment based on the clinical state can be applied consistently. Percentage of participants who show an improvement in SCIO score by 10 percent or more at Week 5 compared to Baseline were reported.

Percentage of Participants Showing 10 Percent or Higher Response in Scoring Clinical Index for Onychomycosis (SCIO) Score at Week 9Baseline and Week 9

The SCIO is based on clinical state and its items include major factors that can have an effect on the outcome of onychomycosis treatment. The factors include the clinical form, depth of an infected area and subungal hyperkeratosis. The SCIO score range from 1 to 30 and higher score indicates more severity. The score is classified into 7 steps and as there is treatment for each step, treatment based on the clinical state can be applied consistently. Percentage of participants who show an improvement in SCIO score by 10 percent or more at Week 9 compared to Baseline were reported.

Percentage of Participants Showing 10 Percent or Higher Response in Scoring Clinical Index for Onychomycosis (SCIO) Score at Week 13Baseline and Week 13

The SCIO is based on clinical state and its items include major factors that can have an effect on the outcome of onychomycosis treatment. The factors include the clinical form, depth of an infected area and subungal hyperkeratosis. The SCIO score range from 1 to 30 and higher score indicates more severity. The score is classified into 7 steps and as there is treatment for each step, treatment based on the clinical state can be applied consistently. Percentage of participants who show an improvement in SCIO score by 10 percent or more at Week 13 compared to Baseline were reported.

Percentage of Participants Showing 10 Percent or Higher Response in Scoring Clinical Index for Onychomycosis (SCIO) Score at Week 25Baseline and Week 25

The SCIO is based on clinical state and its items include major factors that can have an effect on the outcome of onychomycosis treatment. The factors include the clinical form, depth of an infected area and subungal hyperkeratosis. The SCIO score range from 1 to 30 and higher score indicates more severity. The score is classified into 7 steps and as there is treatment for each step, treatment based on the clinical state can be applied consistently. Percentage of participants who show an improvement in SCIO score by 10 percent or more at Week 25 compared to Baseline were reported.

Percentage of Participants Showing 10 Percent or Higher Response in Scoring Clinical Index for Onychomycosis (SCIO) Score at Week 37Baseline and Week 37

The SCIO is based on clinical state and its items include major factors that can have an effect on the outcome of onychomycosis treatment. The factors include the clinical form, depth of an infected area and subungal hyperkeratosis. The SCIO score range from 1 to 30 and higher score indicates more severity.
