简要总结

In this experimental study, researchers will try to find out if treatment of lupus nephritis with a combination of rituximab and cyclophosphamide (CTX), or a combination of rituximab and CTX followed by treatment with belimumab is safe and if this drug combination can block the immune system attacks.

详细描述

Lupus nephritis is a severe form of systemic lupus erythematosus (SLE) with active disease in the kidneys. SLE is a complex disease in which the body's own immune system attacks some of the body parts: the skin, the joints, the kidneys, the nervous system, the heart, the lungs and the blood. The cause of SLE is not known. Treatment for SLE usually involves drugs that are designed to block the immune system attacks. When SLE affects the kidneys (nephritis), stronger immune suppressing treatment is usually needed.

The drugs used in treatment of lupus nephritis often do not cure the disease and can cause serious side effects, including lowering the immune system too much. When the immune system is too low, a person is at a higher risk of getting infections. Therefore, research into new treatments with fewer serious side effects is needed for lupus nephritis.

入选标准

•Diagnosis of Systemic Lupus Erythematosus (SLE) by American College of Rheumatology (ACR) criteria.
•Positive antinuclear antibody (ANA) or positive anti-ds DNA test results at visit -1 or any time within 14 days before visit -
•Active proliferative lupus nephritis, as defined by either of the following:
•Kidney biopsy documentation within the last 3 months of International Society of Nephrology/Renal Pathology Society (ISN/RPS) proliferative nephritis: Class III, Class IV, or Class V in combination with Class III or IV.
•Active urinary sediment and kidney biopsy documentation within the last 12 months of ISN/RPS proliferative nephritis: Class III, Class IV, or Class V in combination with Class III or IV. Active urinary sediment is defined as any one of the following:
•>5 RBC/hpf in the absence of menses and infection;
•>5 White blood cell per high powered field (WBC/hpf) in the absence of infection; or
•Cellular casts limited to RBC or WBC casts.
•Urine protein-to-creatinine ratio (UPCR) >1 at study entry based on a 24-hour collection.
•Ability to provide informed consent.

排除标准

•Hospitalization for treatment of infections, or parenteral (IV or IM) antibacterials, antivirals, anti-fungals, or anti-parasitic agents within the past 60 days.
•Chronic infection that is currently being treated with suppressive antibiotic therapy, including but not limited to tuberculosis, pneumocystis, cytomegalovirus, herpes simplex virus, herpes zoster, and atypical mycobacteria.
•History of significant infection or recurrent infection that, in the investigator's opinion, places the participant at risk by participating in this study.

•Severe, progressive, or uncontrolled renal, hepatic, hematological,gastrointestinal, pulmonary, cardiac, or neurological disease, either related or unrelated to SLE, with the exception of active lupus nephritis (or, in the investigator's opinion, any other concomitant medical condition that places the participant at risk by participating in this study).
•Comorbidities requiring corticosteroid therapy, including those which have required three or more courses of systemic corticosteroids within the previous 12 months.
•Current substance abuse or history of substance abuse within the past year.
•History of severe allergic or anaphylactic reactions to chimeric or fully human monoclonal antibodies.
