Clinical Trial Summary

This randomized, double-blinded dose-finding study evaluates four dose levels of ABY-035, in comparison to placebo, in subjects with moderate to severe plaque psoriasis.

The study consists of 52-week Core study and two optional 52-week periods, Extension and Prolongation of Extension.

The Core study consists of three periods: Induction (placebo-controlled, Week 0-12), Optimization (Week 12-24), and Individualization (Week 24-52).

Description:

The Core study evaluates four doses of ABY-035, in comparison to placebo, in subjects with moderate to severe plaque psoriasis. The treatment periods in the Core study are:

• Induction (Week 0-12) - four dose levels and placebo (Q2W)

• Optimization (Week 12-24) - starting with a possible dose adjustment (all subjects on Q2W) depending on PASI score. Subjects on placebo switch to active drug (Q4W).

• Individualization (Week 24-52) - starting with a switch to Q4W for all subjects. From week 32 dosing interval alters depending on PASI score.

The study is unblinded after completion of the Core study. During the optional Extension and Prolongation of Extension periods, dose levels and intervals alter depending on PASI score.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of subjects with a =90% improvement in Psoriasis Area and Severity Index (PASI90) at week 12	The PASI combines the extent of body surface involvement in the body regions head, trunk, arms, and legs. The percent area of the skin involved is estimated per region (0-100%). The severity is estimated by clinical signs of erythema, induration and scaling, from 0 (no involvement) to 4 (severe involvement). Each area is scored separately and the scores then combined for the final PASI. Overall scores range from 0 (no psoriasis) to 72 (the most severe disease).

Secondary	Change from baseline in target nail Nail Psoriasis Severity Index (NAPSI) at week 12	The NAPSI scale is used to evaluate the severity of psoriasis in the fingernail bed and matrix. The nail is divided into quadrants. Each quadrant is given the score 0 (absence) or 1 (presence) for psoriasis in the beds and matrix, respectively. The NAPSI score of a nail is the sum of each quadrant. The maximum score per nail is 8.; In the target nail NAPSI, the worst affected nail at Baseline is evaluated throughout the study.	Week 12
