Minimizing Glucocorticoid Administration in Patients With Proliferative Lupus Nephritis

Официальное название

Minimizing Glucocorticoid Administration in Patients With Proliferative Lupus Nephritis During the Induction of Remission Period-EUROLUPUS vs. RITUXILUP Regimen: A Randomized Study

Обзор

The aim of the study is to evaluate the efficacy of a therapeutic regimen which decreases glucocorticoid exposure compared with standard therapy in patients with proliferative lupus nephritis during remission induction by evaluating the histological and clinical remission.

Подробное описание

After an initial screening phase during which a first kidney biopsy is performed, all patients that meet the inclusion criteria will be randomized to one of the treatment arms:

* EUROLUPUS regimen: 3 daily pulses of 750 mg of intravenous Methylprednisolone, followed by oral corticosteroid therapy starting with a dose of 0.5 mg / kg / day for 4 weeks, then decreased by 2.5 mg of Prednisolone / day each 2 weeks. A low dose of glucocorticoid (5-7.5 mg / day) is maintained until 24 months after enrollment. All patients will receive Cyclophosphamide intravenously starting day 1, 6 pulses at a fixed dose of 500 mg given at 2 weeks. After 3 months, Azathioprine (2 mg / kg / day) is initiated 2 weeks after the last administration of Cyclophosphamide and maintained for the next 21 months. * RITUXILUP regimen: 2 doses of Rituximab 1 g and Methylprednisolone 500 mg on days 1 and 15. Patients will receive Mycophenolate Mofetil, initially 500 mg twice daily, titrated to a maximum of 1.5 g twice daily, depending on leukocyte count and digestive tolerance, which will be maintained 24 months.

Second kidney biopsy will be performed 6 months after the start of the treatment phase.
