A Study Assessing Rocatinlimab (AMG 451) Monotherapy in Moderate-to-severe Atopic Dermatitis (AD) (ROCKET-Horizon)

EASI was designed and widely used to assess the severity and extent of AD across four anatomical regions. It evaluated key signs of inflammation, including erythema, induration/papulation, excoriation, and lichenification. The total EASI score ranged from 0 to 72, with higher scores indicating more severe disease. EASI 75 was defined as a ≥ 75% reduction from baseline in the total EASI score. Participants initiating rescue therapy for AD were classified as nonresponders at all subsequent time points.

The vIGA-AD was a validated assessment instrument used in clinical studies to globally rate the severity of AD on a 5-point scale ranging from 0 to 4, where 0 = Clear, 1 = Almost clear, 2 = Mild, 3 = Moderate, and 4 = Severe. Higher scores indicated greater disease severity. Participants who achieved a score of 0 or 1 with a ≥ 2-point reduction from baseline were considered to have achieved 'Clear' or 'Almost clear' status. Participants initiating rescue therapy for AD were classified as nonresponders at all subsequent time points.

The Worst Pruritus was assessed daily using an NRS consisting of a single item ranging from 0 to 10, where 10 represented the highest intensity of itch. Participants were asked to rate the intensity of their worst itch using this scale. Participants initiating rescue therapy for AD were classified as nonresponders at all subsequent time points.

A negative change from baseline indicated a reduction in itch intensity.

The SCORAD Itch VAS was a component of the SCORAD tool used to assess the severity of AD using both physician and patient-reported data. Itch VAS scale ranged from 0 to 10, with a higher score indicating more severe AD. Participants initiating rescue therapy for AD were included in the analysis, and each participant's worst observation, including baseline value, before initiation of rescue therapy for AD was carried forward (WOCF) to all subsequent time points. A negative change from baseline indicated a reduction in AD severity.

A negative change from baseline indicated a reduction in AD severity.

The DLQI was a 10-item, self-administered questionnaire, where the total score ranged from 0 to 30; higher scores represented a greater impact of AD. It was designed to measure the health-related quality of life of adult patients suffering from skin disease. The DLQI measured participants' perception of the impact of skin diseases on different aspects of their health-related quality of life over the previous week. Participants initiating rescue therapy for AD were classified as nonresponders at all subsequent time points.

The POEM was a 7-item validated questionnaire used to assess disease symptoms in children and adults, where the POEM total score ranged from 0 to 28; higher scores represented a greater impact of AD. It evaluated the time spent in the past week with AD signs and symptoms: individual items of bleeding, oozing, cracked, flaking, and dry/rough skin, and their impact on sleep. Participants initiating rescue therapy for AD were classified as nonresponders at all subsequent time points.
