Efficacy of Apo805K1 as Assessed by Change From Baseline at Week 12 in Lattice System-Physician Global Assessment (LS-PGA) ScoresBaseline to 12 weeksThe LS-PGA is a standardized method for determining categories of psoriasis severity. The percentage of body surface area involved is assessed on a scale ranging from 1 (0%) to 7 (51-100%); measures of plaque severity (thickness, erythema, and scaling) are assessed using a 4-point scale ranging from none to marked; and an algorithm is used to combine the above scores to determine a final score on a scale ranging from 0 (clear) to 7 (very severe). Thus, a decrease in LS-PGA score indicates improvement. This outcome measure compared the difference in change in LS-PGA score from baseline to Week 12 between the active treatment groups and the placebo group.
Efficacy of Apo805K1 as Assessed by Change From Baseline to Week 12 in Physician Global Assessment (PGA) ScoreBaseline to 12 weeksIn the PGA, the physician assigns a single estimate of a patient's overall severity of the disease using a scale ranging from 0 (Clear) to 7 (Severe). (Unlike the LS-PGA, the individual elements of psoriasis plaque morphology or degree of body surface area involvement are not quantified.) Thus, a decrease in PGA score indicates improvement. This outcome measure compared the difference in change in PGA score from baseline to Week 12 between the active treatment groups and the placebo group.
Efficacy of Apo805K1 as Assessed by Change From Baseline in Psoriasis Area Severity Index (PASI) ScoresBaseline to 12 WeeksPASI is a quantitative measure of psoriasis that combines an assessment of the severity of lesions and a measurement of how much of the body surface area is affected into a single score ranging from 0 (no disease) to 72 (maximal disease). Thus, a decrease in PASI score indicates improvement. This outcome measure compared the difference in change in PASI score from baseline to Week 12 between the active treatment groups and the placebo group.
