Brief Summary:
This is a randomized, double blind, placebo controlled trial of abatacept for the treatment of lupus arthritis and other manifestations of lupus. Patients with lupus and at least 3 tender and 3 swollen joints and </= 20 mg prednisone have other background immune suppressants withdrawn at entry. They can elect to receive up to a total of 320 mg depomedrol (in two or more injections) between the screening visit and the visit 2 months after dosing begins. Abatacept (125 mg) or placebo is administered in weekly subcutaneous doses. After 3 months of treatment patients who are not responding may elect to receive open label abatacept with or without additional standard of care therapies. Such patients are considered non responders. The primary endpoint is the British Isles Lupus Assessment Group Index (BILAG)-linked Combined Lupus Assessment (BICLA) which will require a clinically significant improvement in arthritis and other active features of lupus

Drug Information available for: Abatacept

Arm Intervention/treatment
Active Comparator: Abatacept
Patients receive Abatacept 125 mg subcutaneously weekly for six months. An optional continuation up until 12 months is allowed. Background immune suppressants are withdrawn at the beginning of the study and the option of depomedrol up to 320 mg total (in divided doses) is allowed at any time up through the visit 2 months after study medication is started. After this additional rescue is allowed with any standard of care treatment and/or open label abatacept (since patients are blinded) but this additional rescue will define non-response in the primary endpoint at six months.
Biological: Abatacept
Other Name: Orencia

Placebo Comparator: Placebo
Patients receive placebo instead of Abatacept in a double blind fashion. Otherwise participation is the same, including that at the time of treatment failure they may elect any standard of care treatment and/or to begin taking open label abatacept but this rescue will define non-response in the primary endpoint at six months.
Other: Placebo

Primary Outcome Measures :
  1. British Isles Lupus Assessment Group Index-based Combined Lupus Assessment (BICLA) [ Time Frame: 6 months ]
    The British Isles Lupus Assessment Group Index is a scoring system for progress of disease activity over the prior month with a scoring system that rates each organ system as "A" or severe, "B" or moderate, "C" or mild vs no activity in the past month. To meet the BICLA endpoint requires all baseline severe features (BILAG A) improving to moderate (BILAG B), mild or resolved, and all baseline BILAG B features improving to mild or resolved without increase in any other feature on either the BILAG or a different measure called the SLEDAI (SLE Disease Activity Index). Furthermore there must be no increase in Physician's Global Assessment or any rescue medications after the month 2 visit. Only those meeting all of these criteria meet the primary endpoint.
