Study Comparing SUBA™-Itraconazole With SPORANOX® (Itraconazole) in the Treatment of Onychomycosis
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.

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
- 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
- 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
- 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
- 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
- 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
- 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
- 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 | 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. |
