About

The aim of this post-marketing observational study is to obtain further data on the long term use, safety and efficacy of Zemplar as it is prescribed in the normal clinical setting and according to the approved Summary of Product Characteristics for the treatment of secondary hyperparathyroidism in hemodialysis patients in Greece.

Full description

The primary objective of this study is to evaluate the safety of Zemplar® in the treatment of Secondary hyperparathyroidism (iParathormone>300 pg/mL) in subjects on hemodialysis treated in conditions of usual clinical care.

The primary safety endpoints of this study are to evaluate the safety of Zemplar by recording the number of hospitalizations and days hospitalized.

A secondary efficacy endpoint will be the proportion of subjects achieving therapeutic success. Therapeutic success with Zemplar® will be defined as:

  • 40% reduction in the base iPTH level is achieved, and/or;
  • serum iParathormone level < 300 pg/mL.

Additional secondary endpoints are the incidence (proportion of patients) of clinically meaningful hypercalcemia (defined as corrected serum calcium (Ca) > 11.0 mg/dL taken at 2 consecutive measurements), hyperphosphatemia (defined as serum phosphorous (P)>6.5 mg/dL taken at 2 consecutive measurements), and elevated Ca x P product (defined as serum Ca x P>65 mg^2/dL^2 taken at 2 consecutive measurements). Safety also will be assessed through adverse event monitoring and evaluation of laboratory variables and vital signs.
