DePTH: De-emphasize PTH (NCT06288451)
🩺 Plain-English Summary (8th-Grade Level)
The De-emphasize Parathyroid Hormone (DePTH) Study is a 12-month pragmatic, randomized, parallel-group, active comparator, open-label, blinded end-point study of 90 patients with incident or prevalent secondary hyperparathyroidism and kidney failure treated with in-center hemodialysis. It tests the hypothesis that low fixed-dose oral calcitriol (intervention) will have more favorable effects on a comprehensive panel of biomarkers that assesses mineral metabolism, bone turnover, and serum calcification propensity, compared with variably-dosed intravenous activated vitamin D titrated to PTH targets (usual care).
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (3 items) and avoid the listed exclusions (8 items).
