Condition(s) targeted: Arthritis, Juvenile Rheumatoid; Still's Disease, Juvenile Onset

Intervention: tocilizumab (Biological)

Phase: N/A

Status: Terminated

Sponsored by: Tufts Medical Center

Official(s) and/or principal investigator(s):
Marc D Natter, MD, Principal Investigator, Affiliation: Tufts Medical Center

Summary

The purpose of this study is to see if tocilizumab is safe and effective for treating systemic onset Juvenile Idiopathic Arthritis (soJIA). Another purpose is to see if tocilizumab helps reduce the amount of steroids (prednisone) needed to control symptoms of soJIA.

Clinical Details

Official title: Single Patient Use of Tocilizumab for Treatment of Steroid Dependent, Active Systemic Onset Juvenile Idiopathic Arthritis

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Efficacy of tocilizumab as defined by presence of an equal to or greater than 30% improvement in JIA core set (i.e. ACR JIA30 response)

Efficacy of tocilizumab as defined by reduction of oral prednisone dose by at least 20%, or to less than 0.5mg/kg/day, whichever is of lesser daily dose, while maintaining an ACR JIA30 response

To evaluate the safety of tocilizumab administration in this subject

Secondary outcome:

To assess normalization of laboratory parameters of active disease, specifically C-reactive protein, hemoglobin, platelets, white blood cell count, ferritin, immunoglobulins.

To assess sustained clinical response to tocilizumab, including active joint count, joints with limited range of motion, and absence of fever or rash.

Detailed description: Systemic onset Juvenile Idiopathic Arthritis (soJIA) is a type of arthritis (inflammation of the joints) that occurs with other symptoms including fever, swollen lymph nodes (glands), rash, and body aches. Because soJIA can be difficult to treat, children with soJIA can have severe problems from long-term use of steroids (prednisone). These problems include low bone density (weak bones), fractures, failure to grow properly, and large weight gain. The arthritis that occurs in soJIA often causes damage to many joints. This can make it hard to move around or do basic tasks like dressing. Also, a life-threatening illness called Macrophage Activation Syndrome (MAS) can occur when starting, stopping, or changing drugs that are used to treat soJIA. SoJIA can be hard to treat and many children with soJIA do not respond to drugs that work for other kinds of arthritis. Research doctors have studied a chemical signal called IL-6 that the body uses to manage inflammation. This signal has been found to be very high in patients with active soJIA. A drug called tocilizumab (TCZ) has been designed to block IL-6. For about 6 years, TCZ has been tested in Japan for treating soJIA. It is now being tested in studies in the United States. These studies can have very strict rules for enrolling patients. This trial is a single-patient research study for a subject who otherwise does not meet the rules for enrollment in ongoing trials.
