Study of Zemplar iv in Patients With End Stage Chronic Kidney Disease, Undergoing Haemodialysis

September 19, 2011 updated by: Abbott

A One-year, Multicountry, Multicenter Study of Zemplar Injections in Patients With End Stage Chronic Kidney Disease, Undergoing Hemodialysis, Not Adequately Controlled With Oral Vitamin D Receptor Activator (Calcitriol or Alfacalcidol)

This is the post-marketing study conducted in two countries: Croatia and Serbia. In both countries Zemplar (paricalcitol) is the first injectable form of any Vitamin D Receptor (VDR) activator available for chronic kidney disease patients on hemodialysis. The evaluation of outcomes of VDR activator treatments in clinical practice is a major challenge in the management of this patient population. The aim of this post-marketing observational study is to obtain further data on the outcomes of Zemplar Injection administration during routine clinical use.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a non-interventional, observational study in which Zemplar® Injection is prescribed in the usual manner in accordance with the terms of the local Summary of Product Characteristics (SmPC) with regards to dose, population and indication. The study population consists of participants receiving hemodialysis in whom the diagnosis of secondary hyperparathyroidism has been established, and who are not adequately controlled with the oral VDR activator (calcitriol or alfacalcidol). Participants will be included via consecutive sampling. To be included, participants should have a clinical indication to initiate treatment with Zemplar® Injection due to: (1) a diagnosis of secondary hyperparathyroidism and (2) because they require a change in treatment for secondary hyperparathyroidism (e.g. due to a lack of effectiveness of the previous treatment). Each participant will be observed during his/her Zemplar® Injection treatment regimen for a maximum period of 12 months.

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.
