Clinical response is defined as having vIGA-AD 0 or 1. Relapse is defined as having vIGA-AD ≥3 or loss of EASI-75\^. The validated Investigator Global Assessment scale for atopic dermatitis (vIGA-AD) is an Investigator-completed assessment scale used to determine severity of AD and clinical response to treatment. It is based on a 5-point scale, ranging from 0 (clear) to 4 (severe). The Eczema Area and Severity Index (EASI) is an Investigator-assessed validated tool used to measure the extent (area) and severity of AD. Total score ranges from 0 to 72 with a higher score indicating increased extent and severity of AD. EASI-75 is 75% reduction from baseline in EASI score. The symbol \^ represents "based on parent study baseline".
Maintenance of clinical response is defined as having vIGA-AD 0 or 1 OR EASI-75\^ OR vIGA-AD 0 or 1 and EASI-75\^.

Positive tetanus response is defined as ≥2.5 IU/mL in anti-tetanus immunoglobulin G \[IgG\] titer for participants with a pre-vaccination baseline \[Week 12\] tetanus antibody titer of \>1 IU/mL or a titer ≥ 3-fold increase for participants with a pre-vaccination titer of ≤1 IU/mL).

Severe asthma exacerbation event was defined as worsening of asthma requiring the use of systemic corticosteroids for \>=3 days or, in the case of a stable maintenance regimen of oral corticosteroids (OCS) for the treatment of asthma, a doubling of the dose for 3 or more days, or hospitalization or emergency room visit because of asthma requiring systemic corticosteroids. Annualized rate was the total number of severe asthma exacerbation events divided by the total observation duration and was estimated based on negative binomial regression.
AUC = area under the serum/plasma concentration curve; AUClast = area under the plasma concentration versus time curve calculated using the trapezoidal method from time zero to the real time tlast.
