Long-Term Efficacy and Safety of Upacicalcet in Japanese Hemodialysis Patients with Secondary Hyperparathyroidism: Open-Label 52-Week Study.
Trial report in American journal of nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionUpacicalcet is a novel injectable calcimimetic. 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).
methodsJapanese HD patients with serum intact parathyroid hormone (iPTH) levels >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).
resultsA 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 <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.
conclusionThis 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. Upacicalcet is efficacious in HD patients with mild-to-severe SHPT, with few safety concerns.
