Trial Outcomes & Findings for Phase 3 Study to Evaluate WR 279,396 vs. Paromomycin Alone to Treat Cutaneous Leishmaniasis (in Tunisia) (NCT NCT00606580)

NCT ID: NCT00606580

Last Updated: 2014-07-14

Results Overview

Final clinical cure was defined as an index lesion that met the criteria for initial clinical cure without relapse. Definitions for index lesion outcomes were as follows: * Initial Clinical Improvement: At least 50% to 99% reduction in the size of the measured lesion from the baseline measurement by the Day 42 evaluation. * Initial Clinical Cure: 100% re-epithelialization (ie, a 0 x 0 length x width measurement) of the lesion at the nominal Day 42 evaluation, or initial clinical improvement followed by 100% re-epithelialization by Day 98. * Relapse: Initial clinical cure followed by re-ulceration by Day 168, or initial clinical improvement followed by lesion enlargement by Day 168. * Final Clinical Cure: Initial clinical cure without relapse through study Day 168.Clinical Failure: Lack of at least initial clinical improvement by Day 42, or relapse.

PRIMARY outcome

Timeframe: Day 42, 98, and 168

Population: Modified intention-to-treat (mITT) - all subjects randomized who received at least one treatment of study drug.

Final clinical cure was defined as an index lesion that met the criteria for initial clinical cure without relapse. Definitions for index lesion outcomes were as follows: * Initial Clinical Improvement: At least 50% to 99% reduction in the size of the measured lesion from the baseline measurement by the Day 42 evaluation. * Initial Clinical Cure: 100% re-epithelialization (ie, a 0 x 0 length x width measurement) of the lesion at the nominal Day 42 evaluation, or initial clinical improvement followed by 100% re-epithelialization by Day 98. * Relapse: Initial clinical cure followed by re-ulceration by Day 168, or initial clinical improvement followed by lesion enlargement by Day 168. * Final Clinical Cure: Initial clinical cure without relapse through study Day 168.Clinical Failure: Lack of at least initial clinical improvement by Day 42, or relapse.

Population: Per protocol - all randomized subjects who received at least one treatment of study drug and whose outcomes at Day 42, Day 98 (if applicable) and Day 168 could be assessed. However, a subject was still considered per-protocol if withdrawn early for treatment failure.

Final clinical cure was defined as an index lesion that met the criteria for initial clinical cure without relapse. Definitions for index lesion outcomes as described in the primary outcome measure.

Timeframe: Day 42

Population: mITT dataset

For the first of the above analyses, subjects were considered to have endpoint events at the first assessment on or before Day 42 where complete re-epithelialization occurred at the index lesion that was not followed by a later assessment where ulceration was present. Subjects who did not have complete re-epithelialization by Day 42 or who relapsed after Day 42 were censored in the analysis at the Day 42 assessment. This analysis was only to be conducted through Day 42.
