A Clinical Study Investigating the Safety, Tolerability, PK and PD of PCO371 in Patients With Hypoparathyroidism
A Randomized, Double-Blind, Multiple Ascending Oral Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of PCO371 in Patients With Hypoparathyroidism
This is a multi-center, placebo-controlled, randomized, double-blind, multiple-ascending dose study in patients with hypoparathyroidism.
The total duration of study medication treatment will be 13 weeks and includes a Fixed-Dose Treatment period and a Dose Titration Treatment period. The Fixed-Dose Treatment period consists of multiple daily dosing at a fixed dose level. Once patients have completed the Fixed-Dose Treatment period, patients will enter the Dose Titration Treatment period where PCO371 (or placebo), oral calcium and oral active vitamin D can each be titrated according to the patient's albumin-corrected serum calcium level.
