Intravenous Pulse Cyclophosphamide Therapy in Treatment-Refractory Juvenile Dermatomyositis

Principal Investigator:

Clarissa Pilkington, M.B.B.S.

Study Hypothesis:

Severe clinical features, including severe muscle weakness, cutaneous or gastrointestinal ulcerations, interstitial lung disease and convulsions, would respond to intravenous pulse cyclophosphamide therapy.

Study Design:

Open label, retrospective

Types & Number of IIM Studied:

IMACS Core Set Measures Included:

Physician Global Activity-VAS, Patient Global Activity-VAS, Muscle Strength Testing-MMT, Functional Assessment Tools-CMAS, CHAQ, Laboratory-Muscle Enzymes, Extramuscular Assessment-Extramuscular Global Activity, MD Assessment of Outcome

Primary Outcome:

Examined improvement in core set measures at 6 month and last follow-up evaluation.

Secondary Outcome:

Adverse event assessment

Key Trial Dates:


Funding Sources:

Supported by the Juvenile Dermatomyositis Research Centre and grants from the Cathal Hayes Research Foundation.
