Follow-up Patients With End Stage Renal Disease Receiving Zemplar to Prevent and Treat Secondary Hyperparathyroidism

2014-08-27 03:15:24 | BioPortfolio


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.


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 Ca > 11.0 mg/dL taken at 2 consecutive measurements), hyperphosphatemia (defined as serum P>6.5 mg/dL taken at 2 consecutive measurements), and elevated Ca x P product (defined as serum Ca x P>65 mg2/dL2 taken at 2 consecutive measurements). Safety also will be assessed through adverse event monitoring, changes from baseline in chemistry and hematology laboratory variables, and changes from baseline in vital signs.

Medical and Biotech [MESH] Definitions

A severe irreversible decline in the ability of kidneys to remove wastes, concentrate URINE, and maintain ELECTROLYTE BALANCE; BLOOD PRESSURE; and CALCIUM metabolism. Renal failure, either acute (KIDNEY FAILURE, ACUTE) or chronic (KIDNEY FAILURE, CHRONIC), requires HEMODIALYSIS.

The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

Conditions in which the KIDNEYS perform below the normal level for more than three months. Chronic kidney insufficiency is classified by five stages according to the decline in GLOMERULAR FILTRATION RATE and the degree of kidney damage (as measured by the level of PROTEINURIA). The most severe form is the end-stage renal disease (CHRONIC KIDNEY FAILURE). (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002)

A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.

Sudden liver failure in the presence of underlying compensated chronic LIVER DISEASE (e.g., LIVER CIRRHOSIS; HEPATITIS; and liver injury and failure) due to a precipitating acute hepatic insult.
