Clinical Trial Summary

The MYOCIT study aims to evaluate the efficacy and safety of baricitinib in association with corticosteroids in new-onset patients with juvenile dermatomyositis (JDM) in a phase II trial with the objective to obtain a better efficacy than the conventional combination methotrexate (MTX) and corticosteroids over the 24 week study period. Thus, the investigators hypothesize that baricitinib could be used as a first line treatment in all forms of DMJ, including the most severe one, with a good safety profile.


Description:

Juvenile dermatomyositis (JDM) is a rare and severe paediatric-onset idiopathic inflammatory myopathy, associated with significant morbidity and mortality. The combination of corticosteroids and methotrexate (MTX) is recommended in new-onset JDM according to one randomized trial. However, in this trial, treatment failures were reported in 13/46 (28%) patients and severe JDM, (cutaneous or gastrointestinal ulceration, interstitial pulmonary disease, cardiomyopathy) were not taken into account. These data emphasize the need for a more efficient first-line treatment. Considering: 1) the strong implication of type IFN-I in the pathophysiology of JDM 2) the report of the efficacy and safety of JAK inhibitors (JAKis) (baricitinb, tofacitinib) in about 50 refractory DM patients, and 9 JDM, a trial which evaluates the efficacy and safety of baricitinib in combination with corticosteroids in new-onset JDM is warranted.

Outcome

Type Measure Description Time frame Safety issue
Primary PRINTO 20 (Paediatric Rheumatology INternational Trials Organisation scale) Achievement of the validated juvenile dermatomyositis PRINTO 20 level of improvement. PRINTO 20 level of improvement is defined as a 20% or greater improvement in three or more of the six variables of the juvenile dermatomyositis core set, with one or no variable worsening by more than 30% (muscle strength can not be the variable worsening) :
muscle strength, assessed with the Childhood Myositis Assessment Scale (CMAS),
physician's global assessment of the patient's disease activity (Physician's VAS)
global disease activity assessment through the Disease Activity Score (DAS)
functional ability through the Childhood Health Assessment Questionnaire (C-HAQ)
parent's global assessment of the child's overall wellbeing (Parent's VAS)
health-related quality of life, through the parent version of the Child Health Questionnaire (CHQ-Phs) A higher score is 100% and means a better outcome, a lower score is 0% and means a worse result.
