This phase 3 multicenter open-label study aimed to assess the long-term efficacy and safety of upacicalcet in hemodialysis (HD) patients with secondary hyperparathyroidism (SHPT). Methods Japanese HD patients with serum intact parathyroid hormone (iPTH) levels &gt;240 pg/mL and corrected calcium (cCa) levels ≥8.4 mg/dL were enrolled. Upacicalcet with a dose range of 25-300 µg was administered after each dialysis for 52 weeks. The main efficacy endpoint was the percentage of patients achieving the target iPTH level (60-240 pg/mL). Results A total of 157 patients were enrolled, of whom 138 completed the study. Overall, 94.2% of patients achieved the target serum iPTH level at week 52. Neither symptomatic hypocalcemia nor cCa level &lt;7.5 mg/dL occurred despite the negligible increase of concomitant vitamin D receptor activators and calcium carbonate. Upacicalcet improved the control of serum phosphate (P) and calcium levels regardless of baseline PTH levels and decreased intact fibroblast growth factor-23 levels. The largest parathyroid glands shrank, irrespective of their baseline volume or prior calcimimetic usage. Upacicalcet was well-tolerated, with no adverse events requiring dose reduction. Conclusion This is the first study to show that a calcimimetic improves serum P and cCa control without inducing severe hypocalcemia in patients with iPTH levels ≤300 pg/mL.
