Study Details

Study Description

Brief Summary

The objective of this study is to compare the relative efficacy and safety of SUBA™-Itraconazole Capsules (HalcyGen Ltd) to an already marketed oral formulation of itraconazole SPORANOX® (itraconazole) capsules (Janssen Pharma) in the treatment of onychomycosis of the toenail. Both the test and the reference formulations will also be compared to a placebo formulation to test for superiority.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

Randomized, Double-Blind, Multiple-Site, Placebo-Controlled, Parallel designed study comparing a dosing regimen of 100 mg approximately 30 minutes prior to breakfast for 12 weeks of SUBA™-Itraconazole 50 mg capsules (HalcyGen Ltd) to the approved dosing regimen of 200 mg taken with breakfast of SPORANOX® (itraconazole) 100 mg capsules (Janssen Pharma). Patients will be randomly assigned in a 3:3:1 ratio to the test product 100 mg once-a-day: reference product 200 mg once-a-day: placebo once-a-day. respectively. The patients will complete 5 visits: baseline/screening (within 28 days of randomization), Day 1 (randomization), Week 6, Week 12 and Week 24.

  • Outcome Measures

    Primary Outcome Measures

    1. Non-inferiority Will be Determined by Evaluating the Difference Between the Proportion of Patients in the Test and Reference Treatment Groups Who Are Considered a "Therapeutic Cure" at the End of Study Visit (Week 24) [Week 24]

      If the lower bound 95% confidence interval of the difference between the proportion of patients in the Test group compared to the Reference group considered a Therapeutic Cure at Visit 7 was greater than 20 then non-inferiority was considered to have been demonstrated

    2. Non-inferiority Will be Determined by Evaluating the Difference Between the Proportion of Patients in the Test and Reference Treatment Groups Who Are Considered a "Clinical Cure" at the End of Study Visit (Week 24) [Week 24]

      If the lower bound 95% confidence interval of the difference between the proportion of patients in the Test group compared to the Reference group considered a Clinical Cure at Visit 7 was greater than 20 then non-inferiority was considered to have been demonstrated

    3. Non-inferiority Will be Determined by Evaluating the Difference Between the Proportion of Patients in the Test and Reference Treatment Groups Who Are Considered a "Mycological Cure" at the End of Study Visit (Week 24) [Week 24]

      If the lower bound 95% confidence interval of the difference between the proportion of patients in the Test group compared to the Reference group considered a Mycological Cure at Visit 7 was greater than 20 then non-inferiority was considered to have been demonstrated

    Secondary Outcome Measures

    1. The Proportion of Patients in Each Treatment Group Who Are Considered a "Therapeutic Cure" at the End of Treatment Visit (Week 12) 12). [Week 12]

      If the lower bound 95% confidence interval of the difference between the proportion of patients in the test group compared to the reference group considered a cure at the visit being analyzed was greater than -20 then non-inferiority was considered to have been demonstrated

    2. Non-inferiority Will be Determined by Evaluating the Difference Between the Proportion of Patients in the Test and Reference Treatment Groups Who Are Considered a "Clinical Cure" at the End of Study Visit (Week 12) [week 12]

      If the lower bound 95% confidence interval of the difference between the proportion of patients in the test group compared to the reference group considered a cure at the visit being analyzed was greater than -20 then non-inferiority was considered to have been demonstrated

    3. Non-inferiority Will be Determined by Evaluating the Difference Between the Proportion of Patients in the Test and Reference Treatment Groups Who Are Considered a "Mycological Cure" at the End of Study Visit (Week 12) [week 12]

      If the lower bound 95% confidence interval of the difference between the proportion of patients in the test group compared to the reference group considered a cure at the visit being analyzed was greater than -20 then non-inferiority was considered to have been demonstrated

    Other Outcome Measures

    1. Superiority of Test Treatment Over Placebo for Mycological Cure [week 6]

      All primary and secondary endpoints were tested for superiority against Placebo. The intent to treat (ITT) was used for all superiority testing. For the three primary endpoints and all four dichotomous secondary endpoints, if the difference between the proportion of patients considered a cure in the Test or Reference group was statistically greater (p < 0.05) than the proportion of patients considered a cure in the Placebo group, then superiority of that treatment over placebo was considered to have been demonstrated. A one-sided continuity corrected Z-test was used for superiority testing.

    Title Non-inferiority Will be Determined by Evaluating the Difference Between the Proportion of Patients in the Test and Reference Treatment Groups Who Are Considered a "Clinical Cure" at the End of Study Visit (Week 12)
    Description If the lower bound 95% confidence interval of the difference between the proportion of patients in the test group compared to the reference group considered a cure at the visit being analyzed was greater than -20 then non-inferiority was considered to have been demonstrated
    Time Frame week 12

    7. Other Pre-specified Outcome
    Title Superiority of Test Treatment Over Placebo for Mycological Cure
    Description All primary and secondary endpoints were tested for superiority against Placebo. The intent to treat (ITT) was used for all superiority testing. For the three primary endpoints and all four dichotomous secondary endpoints, if the difference between the proportion of patients considered a cure in the Test or Reference group was statistically greater (p < 0.05) than the proportion of patients considered a cure in the Placebo group, then superiority of that treatment over placebo was considered to have been demonstrated. A one-sided continuity corrected Z-test was used for superiority testing.

    Adverse Events

    Time Frame The safety profile of each treatment group was evaluated by comparing adverse events, monitoring vital signs, EKG parameters, audiology testing, and changes in clinical laboratory results obtained throughout the study, which included the 12 week treatment period and the End of Study Visit at Week 24.

    Limitations/Caveats

    Subjects were followed for 12 weeks after the 12 week treatment period, typically subjects would be followed for at least 24 weeks post-treatment to allow sufficient time for the nail to grow out and therefore maximizing rates of clinical cure
