Abstract:
Secondary hyperparathyroidism (SHPT) is a serious and common complication in patients receiving peritoneal dialysis (PD). Cinacalcet is currently the recommended therapy for SHPT; however, gastrointestinal (GI)-related symptoms can result in low adherence and high discontinuation rates. Evocalcet is a novel calcimimetic agent that has non-inferior efficacy while providing a more tolerable safety profile. Methods This was a multicenter, intra-subject dose-adjustment treatment study evaluating the efficacy and safety of 1–8 mg evocalcet orally administered once daily for 32 weeks for the treatment of SHPT in PD patients. Patients then entered a 20-week extension period (dose range 1–12 mg). The primary endpoint was the proportion of patients who achieved a mean intact parathyroid hormone (iPTH) level of 60–240 pg/mL during the evaluation period (weeks 30–32). Secondary efficacy endpoints included the proportion of patients achieving ≥ 30% decrease in iPTH levels. Results A total of 39 Japanese PD patients with SHPT received evocalcet. The target mean iPTH level of 60–240 pg/mL was achieved by 71.8% (28/39) of patients during the evaluation period and 83.3% (20/24) of patients at week 52. The proportion of patients who achieved ≥ 30% decrease in iPTH levels from baseline was 74.4% (29/39) during the evaluation period and 87.5% (21/24) at week 52. Adverse drug reactions occurred in 46.2% (18/39) of patients, with most being of mild-to-moderate severity including GI-related events. Conclusion This study shows the long-term efficacy and safety of evocalcet when orally administered to PD patients with SHPT once daily.
