Double-blind Phase III maintenance study to assess Rocatinlimab in moderate to severe AD (ROCKET-ASCEND)
Zusammenfassung der Studie
Rocatinlimab (AMG 451) is a protein-based drug specifically designed to bind to a protein called OX40 on cells involved in inflammation and inhibit its function. It may therefore represent an additional option for the treatment of inflammatory skin diseases. Approximately 2200 individuals are expected to participate in the study. The study will last approximately 44 weeks and will include the following phases: • A screening phase of up to 14 days • An initial treatment phase of up to 104 weeks An appointment for safety follow-up, which will take place 16 weeks after the last dose of the investigational product at week 100. If additional safety data are needed to meet regulatory reporting requirements for events that must be reported to an authority, further information from patient records may be required after the study has already concluded. Rocatinlimab is being developed by Amgen Inc., a for-profit biopharmaceutical company. It is currently still in the testing phase and is not approved by any drug regulatory authority (e.g., the US Food and Drug Administration [FDA] or the European Medicines Agency [EMA]) for use in individuals with AD.

Untersuchte Intervention
Participants in study 20210146 will receive subcutaneous injections at a dose of 150 mg every 4 weeks or 150 mg every 8 weeks (+TCS/TCI); or 300 mg every 4 weeks or 300 mg every 8 weeks (+TCS/TCI). Randomization to placebo will be stratified by geographic region and vIGA-AD score at the end of the 24-week parent study in adults (0, 1 or ≥ 2). Participants will be observed for two hours after the first dose of Rocatinlimab on day 1 and for 30 minutes after each subsequent dose. Participants will apply a moisturizer (emollient) twice daily. If participants' symptoms do not improve or worsen after the first 6 weeks and the physician deems additional medication necessary, appropriate medications for the treatment of AD will be used.

Untersuchte Krankheit(en)
Atopic Dermatitis (AD) is a chronic relapsing and remitting inflammatory skin disease. This study aims to investigate the long-term safety, tolerability, and efficacy of Rocatinlimab in patients being treated for moderate to severe AD. Furthermore, the study will examine the efficacy and safety of different dosing regimens in conjunction with topical corticosteroids (TCS) / topical calcineurin inhibitors (TCI) as well as the maintenance of treatment response in patients who are switched from confirmed response to Rocatinlimab to placebo (cohort of adults with randomized treatment withdrawal).
(BASEC)
Patients can only be included in the study if all of the following criteria are met: • Patients have provided informed consent prior to the start of any study-specific activities/measures; or the legally authorized representatives of the patients have provided informed consent if the patients are legally too young to provide their own informed consent; and patients have provided their written consent prior to the start of any study-specific activities/measures in accordance with local regulations and/or guidelines. Attend an appointment at the end of treatment (week 24 for studies with adults or week 52 for studies with adolescents) in a parent Rocatinlimab study (20210142, 20210143, 20210144, 20210145, 20210158 or 20210263) within the last 14 days.

Ausschlusskriterien
Patients will be excluded from the study if any of the following criteria apply: Other conditions • Recently occurring suicidality or suicidal thoughts, as evidenced by agreement to items 4 or 5 of the eC-SSRS (Columbia-Suicide Severity Rating Scale) assessment conducted at screening or on day 1. • Severe depression, as assessed by the investigator during the screening phase or on day 1. Previous/current clinical trial experience • Permanent discontinuation of the investigational product for safety-related reasons, according to the stopping rules defined in the study protocol or conditions/reasons not related to efficacy, during the parent Rocatinlimab study (20210142, 20210143, 20210144, 20210145, 20210158 or 20210263) or during the screening phase or on day 1. • Participation or planned participation in a non-Rocatinlimab study protocol or a study protocol with another investigational product. Pregnant and breastfeeding women are excluded from study participation. Endpoints of the study Primary: Description of the long-term safety and tolerability of Rocatinlimab in patients with moderate to severe AD Secondary: Description of the maintenance of treatment response of the individual Rocatinlimab treatment groups compared to placebo in responders who have responded to Rocatinlimab in monotherapy studies in adults.
