Trial Outcomes & Findings for AN2728 Topical Ointment to Treat Mild-to-Moderate Plaque-Type Psoriasis (NCT NCT01300052)

NCT ID: NCT01300052

Last Updated: 2017-04-17

Results Overview

PGA assessed severity of overall disease activity in participants. It was performed using a 6-point scale graded from 0 - 5, in which 0 = clear (no plaque elevation above normal skin level), 1 = almost clear (essentially flat with possible trace elevation), 2 = mild (slight but definite elevation of plaque above normal skin level), 3 = moderate (moderate elevation with rounded or sloped edges to plaque), 4 = severe (marked elevation with hard, sharp edges to plaque), 5 = very severe (very marked elevation with very hard, sharp edges to plaque). The success in PGA of disease severity was defined as a PGA score of '0 = clear' or '1 = almost clear', with at least 2-grade improvement in PGA from Baseline to Day 84.

PRIMARY outcome

Timeframe: Day 84

Population: ITT population included all randomized participants who received the study medication. Missing data was imputed using last observation carried forward (LOCF) method.

PGA assessed severity of overall disease activity in participants. It was performed using a 6-point scale graded from 0 - 5, in which 0 = clear (no plaque elevation above normal skin level), 1 = almost clear (essentially flat with possible trace elevation), 2 = mild (slight but definite elevation of plaque above normal skin level), 3 = moderate (moderate elevation with rounded or sloped edges to plaque), 4 = severe (marked elevation with hard, sharp edges to plaque), 5 = very severe (very marked elevation with very hard, sharp edges to plaque). The success in PGA of disease severity was defined as a PGA score of '0 = clear' or '1 = almost clear', with at least 2-grade improvement in PGA from Baseline to Day 84.

Population: Safety population included all randomized participants with confirmed usage of the study medication.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to Day 84 that were absent before treatment or that worsened relative to pretreatment state. AEs included both SAE and non-SAE.

Population: Safety population included all randomized participants with confirmed usage of the study medication.

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AEs were classified according to the severity in 3 categories a) mild =AEs does not interfere with participant's usual function b) moderate =AEs interfered to some extent with participant's usual function c) severe =AEs interfered significantly with participant's usual function and required systemic drug therapy. Treatment-emergent were events between first dose of study drug and up to Day 84 that were absent before treatment or that worsened relative to pretreatment state. In this outcome measure, number of mild, moderate and severe TEAEs were reported.

Timeframe: Baseline (Day 1) up to Day 84

Population: Safety population included all randomized participants with confirmed usage of the study medication. Here, 'N' (number of participants analyzed) signifies those participants who were evaluable for this outcome measure.

Local tolerability in participants was evaluated in terms of presence and absence of burning/stinging symptom and its severity in the areas of body where medication was applied. Burning/stinging symptoms were graded on a 4-point scale of 0 - 3 where 0 =none (no stinging/ burning), 1 =mild (slight warm, tingling sensation), 2 = moderate (definite warm; tingling/stinging sensation), 3 = severe (hot, tingling/stinging sensation that caused definite discomfort). Higher scores=Severe symptoms. In this outcome measure, number of participants with none, mild, moderate and severe burning/stinging symptoms were reported.

Local tolerability was evaluated in participants in terms of presence and absence of pruritus symptom and its severity in the areas of body where medication was applied. Pruritus symptoms were graded on a 4-point scale of 0 - 3 where 0 =none (no pruritus), 1 =mild (occasional, slight itching/scratching), 2 = moderate (constant or intermittent itching/scratching which was not disturbing sleep), 3 = severe (bothersome itching/scratching which was disturbing sleep). Higher scores=Severe symptoms. In this outcome measure, number of participants with none, mild, moderate and severe pruritus symptoms were reported.
