Cinacalcet is the only calcimimetic approved for HPT secondary to chronic kidney disease (CDK), parathyroid carcinoma, and, in some countries, primary HPT. Clinical trials showed that cinacalcet reduced PTH and calcemia both in CDK and primary HPT, lowering the risk of bone fractures, surgery, and cardiovascular complications in the former patients. Long-term safety and pharmacoeconomics have to be fully tested yet. Few both in vitro and in vivo studies showed an association between Arg990Gly-CASR polymorphism and cinacalcet sensitivity, though in patients with severe CASR inactivating mutations the drug substantially retained its positive clinical effects. |
