- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Change in local physician global assessment (L-PGA) from baseline, using 8-point severity scale.[Day 1, 8, 15, 29, 43, EOS];Change in Target Plaque Severity Score (TPSS) from baseline using 5-points severity scale.[Day 1, 8, 15, 29, 43 and EOS];Safety and tolerability of AKP-11 will be assessed by monitoring adverse events, vital signs, physical examination, ECG, laboratory variables (haematology, chemistry, urinalysis) and skin irritation assessment using 8 point severity scale.[Timepoints: Day 1, 8, 15, 29 and 43 and End of Study Visit (EOS); 7 days after the last treatment.]
- Secondary Outcome Measures
Name Time Method Change in Target Plaque Area (TPA), using the photos images and tracking the plaque area/s. [Timepoints: Day 1, 15, 29 and 43.];Change in pruritus score, using Visual Analogue Scale (VAS).[Day 1, 8, 15,29, 43 and EOS at the clinical sites and daily on a diary card, using self-assessment on 10-cm horizontal VAS scale,being informed that the beginning of the scale refers to no pruritus (0 points) and the end to the most severe pruritus they can imagine (10 points). ]
