NCT07163611
Objective: To assess the disappearance rate (half-life) of anti-PLA2R antibodies in high-risk primary membranous nephropathy (pMN) patients treated with obinutuzumab (OBI), and to evaluate immunological and clinical remission, adverse events, and quality of life. Design: Open-label, single-center, prospective pilot intervention study conducted at Radboud University Medical Center. Population: 20 adult patients with high-risk PMN, defined by proteinuria ≥3.5 g/24h despite 6 months of supportive treatment with ACE inhibitors or ARBs. Intervention: OBI 1000 mg on days 1 and 15, with two additional infusions after 6 months if anti-PLA2R antibody levels remain positive and proteinuria exceeds 2 g/24h. Follow-up: Patients were monitored at baseline, and at weeks 1, 2, 4, 8, 12, 24, 37, and 52.

The prevalence of chronic kidney disease (CKD) in the adult population is estimated to 10%. CKD increases risk of bone fractures, cardiovascular disease and death. The main role of parathyroid hormone (PTH) is to regulate mineral metabolism, including the calcium and phosphate homeostasis. PTH increases as the kidney function declines, and at end stage kidney disease almost all patients have disturbances in the mineral metabolism. Decreasing bone mineral density is associated with risk of fracture, both in background population and in patients with CKD. For decades, treatment with activated vitamin D, phosphate binders, and calcium supplements has been used for patients with chronic kidney disease and elevated parathyroid hormone, but treatment targets have varied greatly over the years, reflecting the lack of randomized clinical trials with clinical important end points. The purpose of The REPAIR-CKD trial is to determine if treatment of hyperparathyroidism improves the bone mineral density in patients with chronic kidney disease. During this trial it will also be evaluated if it is feasible to obtain a difference in PTH levels when targeting two different levels of PTH. Further this trial will explore if a difference in PTH influences on arterial stiffness, muscle mass, muscle function, bone histology and health related quality of life.
