Trial Outcomes & Findings for A Study Assessing Rocatinlimab in Combination With Topical Corticosteroid and/or Topical Calcineurin Inhibitors in Adult Participants With Moderate-to-severe Atopic Dermatitis (AD) (NCT NCT05724199)

Results Overview

vIGA-AD was a validated instrument rating AD severity on a 5-point scale (0 = Clear; 1 = Almost clear; 2 = Mild; 3 = Moderate; 4 = Severe), with higher scores indicating greater severity. Participants achieving a score of 0 or 1 with ≥2-point reduction from baseline were considered 'Clear' or 'Almost clear'. For rIGA 0/1, when vIGA-AD = 1, investigators answered: "Did participant have barely perceptible erythema, no induration/papulation, no lichenification, and no oozing/crusting?" If "Yes," participant met rIGA 0/1; if "No," they did not. If vIGA-AD = 0, participant met rIGA 0/1. Participants initiating rescue therapy for AD were classified as nonresponders at all subsequent time points.

Participant Flow

This trial was conducted at 180 centers in Europe, North America, Asia, Latin America, and Oceania between February 2023 to December 2024.

Participants with moderate-to severe atopic dermatitis (AD) were randomized in a 5:4:4 ratio into 3 treatment groups for a duration of 24 weeks to receive either rocatinlimab 300 mg in combination with topical corticosteroids and/or topical calcineurin inhibitors (TCS/TCI), rocatinlimab 150 mg in combination with TCS/TCI, or matching placebo in combination with TCS/TCI.

Population: FAS: All randomized participants. Participants were analyzed according to the randomized treatment.

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.

Population: FAS: All randomized participants. Participants were analyzed according to the randomized treatment. Only participants with baseline DLQI ≥ 4 were included in the analysis.

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.

Population: FAS: All randomized participants. Participants were analyzed according to the randomized treatment.

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 patients' 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 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 the impact of AD on health-related quality of life.

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.

Results disclosure agreements

Principal investigator is a sponsor employee The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results after completion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
