Condition systemic lupus erythematosus
Treatment non-interventional
Sponsor XDx
Start date December 2007
End date June 2010
Trial size 1000 participants
Trial identifier NCT00671047, SL105


The goal of this study is to enable the study sponsor to develop a new blood test method for clinicians to accurately predict which individuals with lupus will flare, when the flare will occur, and flare severity. Ultimately such a newly derived test would allow treating physicians to start pre-emptive therapy early, with the goal of achieving remission quickly and with a shorter duration of treatment; identify individuals who will have less severe flares and will thus require less aggressive treatments; or intensify and lengthen treatment for those individuals who will need such therapy.

The design of this study is to follow individuals with a known diagnosis of SLE for changes in disease activity during the course of one year of observation. Clinical data and blood and urine samples will be collected at scheduled monthly visits. The clinical data and blood samples will be used for identifying gene expression profile(s) that are associated with increases in SLE disease activity (lupus "flares").

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Individual has met the diagnostic criteria for SLE (at least 4 out of the 11) American College of Rheumatology (ACR) criteria and: - Has experienced specific manifestations of lupus disease activity within the last 12 months including the following: - Lupus nephritis (kidney disease); vasculitis and or central nervous system involvement and/or: - Required treatment with at least 20 mg per day of prednisone (or equivalent) and/or: - Required hospitalization directly due to SLE disease Exclusion Criteria: - Subjects unable or unlikely to cooperate with the procedures of the protocol - Substance abuse / dependence that in the opinion of the investigator could compromise the subject's ability to complete the study - Subject with a more dominant autoimmune disease, e.g. Rheumatoid arthritis, Sjogren's syndrome, multiple sclerosis, scleroderma - History of malignancy within the last five years with the exception of basal cell carcinoma - Active infection: Known HIV positive status, currently active tuberculosis , active infection receiving antibiotics - Had tissue or organ transplantation (including bone marrow) - On chronic hemo- or peritoneal dialysis

Additional Information

Official title The Systemic Lupus Erythematosus (SLE) Activity Gene Expression (SAGE) Study
Description This study is currently enrolling individuals who have an established diagnosis of SLE to participate. There is no cost to volunteers who participate and the study pays for the visits to the clinics for monthly collection of clinical information and blood and urine samples. Women who are or become pregnant may participate in the study with the recommendation of their health care providers and the study doctors.
