Acerca de la investigación
The study is a phase II trial designed to evaluate the clinical efficacy, safety, and tolerability of MAS825 (arumakimig) in pediatric and adult participants with Still's disease
Leer la descripción completa
This is a multicenter, open-label, single-arm study to assess clinical efficacy, safety and tolerability of MAS825 in participants (both pediatric and adult) with Still's disease who have had inadequate response to IL-1 and/or IL-6 or other available therapies. Participants with associated lung disease and/or macrophage activation syndrome may also be included.
This study has three periods (Screening, Treatment Period 1, and Treatment Period 2) and a total duration of approximately 16 months.

Medidas principales
Number of participants with clinical response based on one set of response criteria
Plazo: Day 85
Established measure for efficacy of treatments in the rheumatologic conditions taking into account self-assessment, function and survival.
Medidas secundarias
Number of participants with clinical response based on another set of response criteria
Plazo: Day 85
Established measure for efficacy of treatments in the rheumatologic conditions taking into account self-assessment, function and survival.
Response based on a biomarker level
Plazo: Baseline, Day 85
To evaluate the efficacy of MAS825 in reducing clinical disease activity
Change in physician assessment based on laboratory features of MAS825
Plazo: Baseline, 15 months
To assess the effect of MAS825 on macrophage activation syndrome
Change from baseline in Glucocorticoid (GC) dose
Plazo: Baseline, Day 85, Month 6, Month 12
To evaluate the efficacy of MAS825 as a glucocorticoid-sparing agent
Change from baseline in patient/parent assessment of physical function as assessed by Quality of Life instrument
Plazo: Baseline, Day 85
To evaluate the efficacy of MAS825 in improving participant's quality of life
Clinically inactive disease whilst on non-treatment dose corticosteroid at any time during the study
Plazo: 15 months
The number of participants with inactive disease will be assessed. Disease activity will be evaluated by the investigator based on physical examination and laboratory parameters.
Inactive disease is defined according to protocol-specific criteria, which include clinical signs, laboratory values, and physician assessment.
