Outcomes
Primary Outcomes
Number of Investigator's Global Assessment (IGA) Responders at Day 29 Following Treatment With ASB17061 Capsules or Placebo in Adults With Atopic Dermatitis
Time Frame: Baseline up to 29 days after initial dose.
Participants with an IGA score of 0 or 1 were considered IGA responders. The investigator provided an overall assessment of disease severity using the IGA, which consists of a 6-point scale from a minimum of 0 and a maximum of 6. Higher scores indicate a worse outcome and lower scores indicate a better outcome. (0 = clear; 1 = almost clear; 2 = mild disease; 3 = moderate disease, 4 = severe disease; and 5 = very severe disease).
Number of Investigator's Global Assessment (IGA) Responders By Subgroup at Day 29 Following Treatment With ASB17061 Capsules or Placebo in Adults With Atopic Dermatitis
Time Frame: Baseline up to 29 days after initial dose.
Participants with an IGA score of 0 or 1 were considered IGA responders. The investigator provided an overall assessment of disease severity using the IGA which consists of a 6-point scale from the minimum of 0 to a maximum of 6. Higher scores indicate increasing severity.. (0 = clear; 1 = almost clear; 2 = mild disease; 3 = moderate disease, 4 = severe disease; and 5 = very severe disease) and an overall assessment of the disease severity of the entire body using the Eczema Area and Severity Index (EASI). A composite index, the EASI has a minimum score of 0 (clear) and a maximum score of 72 (very severe); A value less than 15 indicates less severe, and 15 or greater indicates more severe. Lichenification was evaluated on a scale of 0 (none) as the minimum to 3 (severe) as the maximum, and the score of each body region was summed (0 to 12). A percent body surface area (BSA) involved less than 15 is less severe and 15 or greater more severe.
Secondary Outcomes
- Mean Change From Baseline in Eczema Area and Severity Index Score (EASI) Following Treatment With ASB17061 Capsules or Placebo in Adult Participants With Atopic Dermatitis at Day 29(Baseline up to 29 days after initial dose.)
- Mean Change From Baseline in The Percentage of Body Surface Area (BSA) Involved Following Treatment With ASB17061 Capsules or Placebo in Adult Participants With Atopic Dermatitis at Day 29(Baseline up to 29 days after initial dose.)
- Mean Change From Baseline in Pruritus Score Following Treatment With ASB17061 Capsules or Placebo in Adult Participants With Atopic Dermatitis at Day 29(Baseline up to 29 days after initial dose.)
- Mean Change From Baseline in Insomnia Score Following Treatment With ASB17061 Capsules or Placebo in Adult Participants With Atopic Dermatitis at Day 29(Baseline up to 29 days after initial dose.)
- Plasma Concentrations of ASB17061 and ASB17584 Over Time Following Treatment With ASB17061 Capsules in Adult Participants With Atopic Dermatitis(Baseline (Day 1 Predose) up to Day 8, Day 15, and Day 22 at 0 to 2.5 hours, 2.5 to 5 hours, 5 to 10 hours, up to Day 29 at 24-32 hours postdose.)
- Minimum Observed Plasma Concentration (Cmin) of ASB17061 and ASB17584 Following Treatment With ASB17061 Capsules in Adult Participants With Atopic Dermatitis(Baseline (Day 1 Predose) up to Day 8, Day 15, and Day 22 at 0 to 2.5 hours, 2.5 to 5 hours, 5 to 10 hours, up to Day 29 at 24-32 hours postdose.)
- Maximum Observed Plasma Concentration (Cmax) of ASB17061 and ASB17584 Following Treatment With ASB17061 Capsules in Adult Subjects With Atopic Dermatitis(Baseline (Day 1 Predose) up to Day 8, Day 15, and Day 22 at 0 to 2.5 hours, 2.5 to 5 hours, 5 to 10 hours, up to Day 29 at 24-32 hours postdose.)
- Average Plasma Concentration (Cavg) of ASB17061 and ASB17584 Following Treatment With ASB17061 Capsules in Adult Participants With Atopic Dermatitis(Baseline up to Predose, up to 0 to 2.5 hours, up to 2.5 to 5 hours, up to 5 to 10 hours, up to Day 29 (24-32 hours).)
