PRINCETON, N.J., Feb. 26, 2025 /PRNewswire/ -- Kyowa Kirin Co., Ltd. (TSE: 4151) today announced that results of the Phase 3 ROCKET HORIZON trial of rocatinlimab, an investigational therapy targeting the OX40 receptor (OX40R) in patients with moderate-to-severe atopic dermatitis (AD), will be presented at the American Academy of Dermatology (AAD) 2025 Annual Meeting to be held in Orlando, Florida from March 7-11, 2025.
AD, a chronic, heterogeneous, inflammatory disease characterized by skin redness, pruritus, and pain, is driven by skin barrier disruption and T cell–dependent inflammatory pathways. Expansion of OX40R+ pathogenic T cells leads to T-cell imbalance, a root cause of inflammatory diseases including AD.
Title: Rocatinlimab Significantly Improved Clinical Signs and Symptoms by Targeting OX40R+ T cells in Patients with Moderate-to-Severe Atopic Dermatitis: Results from the Phase 3 ROCKET
HORIZON Trial
Presenter: Emma Guttman-Yassky, MD, PhD
Date: Saturday, March 8th Time: 1 -4 pm EST
Location: Orange County Convention Center, Chapin Theater Level 2, Orlando, Fla.
ROCKET HORIZON and the ROCKET Phase 3 Program
ROCKET HORIZON is a Phase 3, randomized, placebo-controlled, double-blind trial assessing the efficacy, safety and tolerability of rocatinlimab monotherapy in adults with moderate to severe atopic dermatitis. The trial includes 726 adult patients who were randomized to receive rocatinlimab or placebo administered through a subcutaneous injection every four weeks for 24 weeks with a loading dose at week two. Co-primary endpoints for the trial are achievement of a Validated Investigator Global Assessment for Atopic Dermatitis (vIGA-ADTM) score of 0 (clear) or 1 (almost clear) with a ≥ 2-point reduction from baseline at week 24 and achievement of ≥ 75% reduction from baseline in Eczema Area and Severity Index score (EASI-75) at week 24. (In the US, a more stringent Investigator Global Assessment, revised IGA (rIGA), replaces vIGA in the co-primary endpoint.) Key secondary endpoints included the impact of rocatinlimab on itch as well as safety and tolerability. ROCKET is a comprehensive, global Phase 3 clinical trial program comprised of eight studies intended to establish the safety and efficacy profile of rocatinlimab in adults and adolescents with moderate to severe AD across multiple dosing regimens.
About Moderate to Severe Atopic Dermatitis
Atopic dermatitis, the most common form of eczema, is a chronic inflammatory disease that causes excessively dry, itchy skin that can be painful. People with moderate to severe atopic dermatitis experience chronic symptoms, intensified by unpredictable flare-ups that can be painful and disruptive to everyday life. Almost half of these patients report severe itching, leading to repeated scratching which can cause the skin to thicken and become vulnerable to infection. Atopic dermatitis (all severities) affects 15-20% of children and up to 10% of adults. T-cell imbalance is a root cause of atopic dermatitis, contributing to clinical manifestations including the disease's recurring, unpredictable symptoms.
