A Study to Assess Adverse Events and Disease Activity With Cedirogant (ABBV-157) in Adult Participants With Moderate to Severe Psoriasis

Phase 2

Psoriasis

Brief Summary

Psoriasis is a chronic disease characterized by marked inflammation and thickening of the skin that results in thick, scaly skin plaques. This study assessed how safe and effective cedirogant (ABBV-157) was compared to placebo in adult participants with moderate to severe psoriasis. Efficacy and safety-related measurements assessed disease activity in participants with plaque psoriasis.

Cedirogant (ABBV-157) is an investigational drug being developed for the treatment of chronic plaque psoriasis. Participants were put into 1 of 4 groups, called treatment arms and each group received a different treatment. There was a 1 in 4 chance that participants were assigned to placebo.

Participants received oral daily doses of cedirogant or placebo capsules for 16 weeks.

There may have been a higher burden for participants in this study compared to usual standard of care. Participants attended regular visits per routine clinical practice. The effect of the treatment was checked by medical assessments, checking for side effects, and questionnaires.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving 75% Improvement in Psoriasis Area Severity Index (PASI) Score (PASI 75) at Week 16Baseline, Week 16

The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI 75 is defined as at least a 75% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving a Static Physician Global Assessment (sPGA) Score of Clear or Almost Clear at Week 16At Week 16

The static Physicians Global Assessment (sPGA) is an assessment by the investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale ranging from 0 (none) to 4 (severe). The sPGA composite score ranges from 0 to 4 and is calculated as Clear (0) = 0 for all three; Almost clear (1) = mean \>0, \<1.5; Mild (2) = mean ≥1.5, \<2.5; Moderate (3) = mean ≥2.5, \<3.5; and Severe (4) = mean ≥3.5.

Percentage of Participants Achieving 100% Improvement in Psoriasis Area Severity Index (PASI) Score (PASI 100) at Week 16Baseline, Week 16

The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI 100 is defined as at least a 100% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100.

Percentage of Participants Achieving 50% Improvement in Psoriasis Area Severity Index (PASI) Score (PASI 50) at Week 16Baseline, Week 16

The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI 50 is defined as at least a 50% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100.

Percentage of Participants Achieving 90% Improvement in Psoriasis Area Severity Index (PASI) Score (PASI 90) at Week 16Baseline, Week 16

The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI 90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100.

Percentage of Participants Achieving Psoriasis Symptoms Scale (PSS) Total Score of 0 at Week 16 for Those With PSS >0 at BaselineBaseline, Week 16

The PSS is a 4-item patient-reported outcome (PRO) instrument that assesses the severity of psoriasis symptoms in participants with moderate to severe psoriasis. The symptoms included are: pain, redness, itching and burning from psoriasis. Current symptom severity is assessed as a daily diary, using a 5-point scale ranging from 0 (none) to 4 (very severe). The PSS total score is calculated by summing the scores of the questions and ranges from 0 to 16, where the higher the score, the greater the severity of psoriasis symptoms.

Percentage of Participants Achieving an Itch Numerical Rating Scale (NRS) ≥4-Point Improvement From Baseline at Week 16 for Participants With Itch NRS ≥4 at BaselineBaseline, Week 16

The itch NRS is an 11-point scale that participants completed to describe the intensity of their itch using a 24-hour recall period. The itch NRS asked the participants to: "Please rate your itching severity due to your psoriasis by circling the number that best describes your worst level of itching in the past 24 hours?" The itch NRS scale scores vary between 0, representing "no itching" and 10, representing "worst itch imaginable."
