Study to Evaluate the Effect of Intravenous (IV) Paricalcitol (Zemplar) on Cardiac Morbidity in Patients With Chronic Kidney Disease (CKD) Stage 5 Over 2 Years

June 9, 2014 updated by: AbbVie (prior sponsor, Abbott)

Postmarketing Observational Study to Evaluate the Effect of Zemplar (Paricalcitol IV) on Cardiac Morbidity in Patients With Chronic Kidney Disease Stage 5 Over 2 Years.

The purpose of this study was to ascertain the percentage of cardiac patients with chronic kidney disease (CKD) stage 5 treated with paricalcitol IV achieving intact parathyroid hormone (iPTH) levels in target range of Kidney Disease Outcomes Quality Initiative (K/DOQI) treatment guidelines (150 - 300 pg/mL) after 2 years.

Detailed Description

Secondary hyperparathyroidism (SHPT) is a frequent complication in patients with chronic kidney disease (CKD) stage 5 receiving dialysis. SHPT is an adaptive response to CKD and is characterized by an elevation in parathyroid hormone (PTH) and consecutively high calcium levels. Elevations in calcium levels, phosphate levels, and PTH are correlated with CKD disease progression as well as development or aggravation of cardiovascular impairment. Many CKD patients cannot be treated well with Vitamin D analogues because of effects on calcium. Hypercalcemia is a well - known factor for cardiac disease. No data are available in Austria for a cohort with cardiac disease treated with Zemplar (paricalcitol IV).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Time Frame
Percentage of Participants Achieving an Intact Parathyroid Hormone (iPTH) Level Within the Target Range
