Condition rheumatoid arthritis
Treatment abatacept
Phase phase 3
Sponsor University of California, Los Angeles
Start date March 2011
End date February 2014
Trial size 24 participants
Trial identifier NCT01299961, IND 111281, UCLA Rheumatology RA 001


Rheumatoid arthritis (RA) is a chronic inflammatory disease (a long-lasting disease causing pain and swelling) associated with significant health problems. It is a difficult disease to manage as the disease is often unpredictable. RA causes inflammation (swelling) of the joints that can cause joint damage, deformity, and progressive disability and impairment. It is estimated that 1% of the world's population suffers from this disease.

The purpose of this research study is to determine if a change in inflammation seen on the ultrasound is a good indicator of how subjects' rheumatoid arthritis is responding to treatment of subcutaneous abatacept at 3 weeks, 3 months, 6 months, and 12 months.

Study Design

Allocation non-randomized
Intervention model single group assignment
Masking open label
All subjects will receive an injection of 125 mg of abatacept once a week up to 12 months.
125 mg once a week up to 12 months.

Primary Outcomes

time frame: baseline, 12 months

Secondary Outcomes

12 month change in Disease activity score (DAS); DAS28/ESR-4 item
time frame: baseline, 12 months
12 month change in Health assessment questionnaire-disability index (HAQ-DI)
time frame: baseline, 12 months
