Observational Study to Evaluate the Time to Achieving the Maintenance Dose of Zemplar® (Paricalcitol Injection) in the Treatment of Patients Suffering From End-stage Renal Disease and Severe Over-reactivity of the Parathyroid Glands

January 11, 2013 updated by: AbbVie (prior sponsor, Abbott)

Post-marketing Observational Study to Evaluate the Time to Achieving the Maintenance Dose of Paricalcitol i.v. in the Treatment of Chronic Kidney Disease (CKD) 5 Stage Patients With (Severe) Secondary Hyperparathyroidism in Hungary

This observational study will evaluate the clinical benefit of Zemplar (paricalcitol injection) in daily routine practice in end-stage renal disease patients with severe over-reactivity of parathyroid glands. Participants will be followed for 6 months. Data will be collected from participants initiated on Zemplar therapy according to standard of care. The time to achieving the maintenance dose of Zemplar (paricalcitol injection), the proportion of participants achieving target parathyroid hormone levels, and prevalence of elevated serum calcium and phosphate levels will be evaluated.

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.

Detailed Description

Prospective data collection started at initial dosing with Zemplar (paricalcitol injection) and ended up to 6 months later. If available, retrospective data on vitamin D treatment as well as on the incidence of hypercalcaemia and hyperphosphataemia in the 6 months leading up to paricalcitol treatment were also collected. Eight visits were planned for documentation of prospective data. In accordance with the non-interventional character of the study, only diagnostic and monitoring procedures were applied which are part of the routine medical care of secondary hyperparathyroidism.

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

Study Population

Description

Inclusion Criteria:

Based on the current Hungarian Summary of Product Characteristics for Zemplar (paricalcitol injection), the patient is entitled to treatment with paricalcitol injection and:

  1. ≥ 18 years of age,
  2. Willing to sign the patient information and informed consent form,

  3. Chronic kidney disease (CKD) stage 5 patient receiving haemodialysis with a diagnosis of secondary hyperparathyroidism (SHPT), whose intact parathyroid hormone (iPTH) level is:

    • between 500-800 pg/mL with at least two abruption of conventional vitamin D therapy due to elevated serum calcium level (i.e. > 2.4 mmol/L) in the medical history, or
    • higher than 800 pg/mL and parathyroidectomy is contraindicated.
  4. The patient is planned to receive paricalcitol treatment independently from his/her participation in this study.

Exclusion Criteria:

Patients cannot be enrolled in the study if any of the following exclusion criteria apply:

  1. The patient is already treated with Zemplar (paricalcitol injection),
  2. Any contraindication exists as stated in the current Hungarian Summary of Product Characteristics for Zemplar (paricalcitol injection),
  3. Patients who decline to participate in the study or decline to sign the patient information/informed consent form.

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
Measure Description
Time Frame
Time (in Weeks) From Treatment Initiation to Achieving Maintenance Dose of Zemplar (Paricalcitol Injection)
Time Frame: 6 months
Maintenance dose is defined as weekly dose of paricalcitol that results in at least 2 consecutive intact parathyroid hormone (iPTH) values within the target therapeutic range of 150 - 300 pg/mL, corresponding to 15.9 - 31.8 pmol/L.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
