Calcimimetics treatment strategy for serum calcium and phosphate management in patients with secondary hyperparathyroidism undergoing dialysis: A systematic review and meta‐analysis of randomized studies

INTRODUCTION: Several calcimimetics, other than cinacalcet, are commercially available; however, their effects on calcium and phosphate levels have not yet been fully studied. We conducted a systematic review and meta-analysis of randomized controlled trials to evaluate the impact of calcimimetics on the management of serum calcium and phosphate levels in patients with secondary hyperparathyroidism undergoing dialysis. METHODS: A systematic literature search through October 2023 and a meta-analysis were conducted on the effects of upacicalcet, etelcalcetide, evocalcet, and cinacalcet on serum calcium and phosphate levels in patients with secondary hyperparathyroidism undergoing dialysis; we searched PubMed, Ovid MEDLINE, and the Cochrane Central Register of Controlled Trials, and 21 studies comprising 6371 patients undergoing dialysis were included. RESULTS: Participants treated with calcimimetics had lower serum calcium and phosphate levels than placebo. CONCLUSION: Calcimimetics significantly reduced serum calcium and phosphate levels compared to placebo in patients with secondary hyperparathyroidism undergoing dialysis, independent of therapeutic strategy or concomitant vitamin D treatment.
