Inclusion Criteria:

  • AD as defined by the American Academy of Dermatology Consensus Criteria.

Exclusion Criteria:

  • Skin comorbidities that may interfere with study assessments such as psoriasis, tinea corporis, lupus erythematosus.
  • Conditions that may predispose the patient to excessive bleeding.
  • Any other clinically significant disease, condition, or medical history that, in the opinion of the Investigator, would interfere with participant safety, trial evaluations, and/or trial procedures.

Proportion of participants achieving EASI-75
Defined as reduction of EASI score by ≥75% from baseline
Proportion of participants with reduction of weekly average of daily peak pruritus Numerical Rating Scale (PP-NRS) of ≥4 points
Time to onset of effect on pruritus
Defined as ≥4 points reduction of weekly average of daily PP-NRS from baseline during the 16-week treatment period
Absolute change in EASI score
Proportion of participants achieving EASI-50/90
Defined as reduction of EASI score by ≥50% or ≥90% from baseline
Change in percent body surface area (BSA) of EASI
Change on weekly average of daily PP-NRS

5. Study Description

Brief Summary
This is a parallel, treatment, Phase 2, double-blind, 2-arm, placebo-controlled study with 2 staggered cohorts (2 arms in each cohort) to evaluate the efficacy and safety of rilzabrutinib in adult participants (aged at least 18 years) with moderate-to-severe AD and intolerance or inadequate response to topical corticosteroids (TCS). In parallel to the main study, Japanese participants will be enrolled in a separate sub-study and randomized to receive: Rilzabrutinib TID, Rilzabrutinib BID, or Matching Placebo TID. The total study duration per participant is expected to be approximately 21 weeks, including up to 4 weeks of screening, 16 weeks of on-treatment double-blind period, 1 week of post-treatment follow-up.
