  • Publication number: 20160331765
    Abstract: The method of treating elevated blood levels of iPTH by increasing or maintaining blood concentrations of both 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D in a patient by administering, as necessary, both Vitamin D repletion and Vitamin D hormone replacement therapies, is disclosed. The blood concentrations of 25-hydroxyvitamin D are increased to and maintained at or above 30 ng/mL, and blood concentrations of 1,25-dihydroxyvitamin D are increased to or maintained within a patient's normal historical physiological range for 1,25-dihydroxyvitamin D without causing substantially increased risk of hypercalcemia, hyperphosphatemia or over suppression of plasma iPTH in the patient. The blood levels of 25-hydroxyvitamin D are maintained at or above 30 ng/mL between doses of Vitamin D repletion therapies, and the blood levels of 1,25-dihydroxyvitamin D are maintained in the patient's normal historical physiological range between doses of Vitamin D hormone replacement therapies.

  • Publication number: 20160038514
    Abstract: Methods, compositions, and kits for adjunctive therapy using 25-hydroxyvitamin D are disclosed. The 25-hydroxyvitamin D may be administered with an agent that increases the risk of hypocalcemia, such as cinacalcet or a salt thereof, and/or an anticancer agent. The adjunctive therapy is effective to treat and prevent iatrogenic hypocalcemia and/or secondary hyperparathyroidism, as well as delay cancer progression and the time to a post-treatment skeletal related event.
