About this study

Official title: Post Marketing Observational Study to Assess Patient Management Practices and Quality of Life With the Capsules Form of Paricalcitol in the Treatment of SHPT in Stage 3 - 5 Chronic Kidney Disease Patients Not Yet on Dialysis Under Conditions of Usual Clinical Care (CAPITOL)

Paricalcitol capsules (Zemplar®) received marketing authorization in Sweden in late 2007 for the prevention and treatment of secondary hyperparathyroidism in patients with Stage 3 \& 4 Chronic Kidney Disease (CKD). Accordingly, additional data is needed to evaluate the effectiveness and safety of paricalcitol therapy under conditions of usual clinical care in Sweden.

This observational study is designed to collect data to evaluate safety and effectiveness during 6 months of therapy with paricalcitol capsules prescribed for patients with CKD Stages 3-5 not yet on dialysis. Data will also be collected on patient quality of life and costs associated with patient care.

Read the detailed description

This observational study is designed to collect data to evaluate safety and effectiveness during 6 months of therapy with paricalcitol capsules prescribed in accordance with the terms of the marketing authorization for patients with Chronic Kidney Disease (CKD) Stages 3-5 not yet on dialysis. Data will also be collected on patient quality of life and costs associated with patient care. A retrospective chart review of patient laboratory and medication history will provide historical data to determine drivers for initiation of paricalcitol therapy.

The primary goal of this post-marketing observational study (PMOS) is to further characterize the prescribing habits and patient management practices of physicians prescribing paricalcitol capsules and to assess the metabolic safety and effectiveness of paricalcitol capsules for the treatment of secondary hyperparathyroidism in Stage 3-5 CKD patients not yet on dialysis under conditions of usual clinical care. Focus will be to examine the practice of dose titration in early stages of CKD, understand real-world management of intact parathyroid hormone levels, understand real-world incidence and management of abnormalities in serum calcium and phosphate, and to examine patient bone and mineral profiles and medical history to understand drivers for paricalcitol capsules use.

Patients prescribed paricalcitol therapy for the first time will be asked to participate in the study. Enrolled patients will be followed for 6 months.

Paricalcitol capsulesPatients with secondary hyperparathyroidism associated with Stage 3 - 5 CKD and not yet on dialysis and prescribed paricalcitol capsules in accordance with the terms of the marketing authorization in Sweden.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Intact Parathyroid Hormone at 6 Months

    Measured: Baseline and 6 months

  2. Percentage of Participants With Intact Parathyroid Hormone Within K/DOQI Target Range at Baseline and 6 Months

    Kidney Disease Outcomes Quality Initiative (K/DOQI) target intact parathyroid hormone (iPTH) levels are:

    Stage 3 CKD (estimated Glomerular Filtration Rate* [eGFR] 30 - 59 mL/min): 3.85 - 7.7 pmol/L;

    Stage 4 CKD (eGFR 15 - 29 mL/min): 7.7 - 12.1 pmol/L;

    Stage 5 CKD (eGFR < 15 mL/min): 16.5 - 33 pmol/L.

    *Calculated using the Modification of Diet in Renal Disease formula.

    Measured: Baseline and 6 months

  3. Percentage of Participants With Elevated Serum-Phosphorus (s-P) Levels at Baseline and 6 Months

    Elevated serum phosphorus is defined according to the 2003 Kidney Disease Outcomes Quality Initiative (K/DOQI) target definitions as:

    Stage 3 CKD: ≥ 1.49 mmol/L;

    Stage 4 CKD: ≥ 1.49 mmol/L;

    Stage 5 CKD: > 1.78 mmol/L.

    Measured: Baseline and 6 months

  4. Percentage of Participants With Elevated Serum-Calcium (s-Ca) Levels at Baseline and 6 Months

    Elevated serum calcium is defined according to the 2003 Kidney Disease Outcomes Quality Initiative (K/DOQI) target definitions of s-Ca above 2.37 mmol/L.

    Measured: Baseline and 6 months

Secondary outcomes (6)
  1. Change From Baseline in Proteinuria

    Proteinuria is the presence of excess serum proteins, or albumin, in the urine. Proteinuria was measured by the amount of albumin per liter of urine.

    Measured: Baseline and Month 6

  2. Percentage of Participants With a Reduction of Proteinuria of at Least 15% From Baseline

    Measured: Baseline and 6 months

  3. Change From Baseline in Quality of Life Assessed by the Kidney Disease Quality of Life-Short Form (KDQOL-SF)

    The KDQOL-SF is a self-report measure developed for individuals with kidney disease. It includes 43 end-stage renal disease (ESRD)-targeted items focused on particular areas of concern for individuals with kidney disease (Symptoms/problems, Effects of the disease on daily life, Burden of disease, Work status, Cognitive function, Quality of social interaction, Sexual function, Sleep, and Social support), 36 items (SF-36) that provide 8 measures of physical and mental health (Physical functioning, Role limitations caused by physical health limitations, Role limitations caused by emotional health problems, Social functioning, Emotional well-being, Pain, Energy/fatigue and General health perceptions), and 1 overall health rating item where respondents rate their health on a scale from 0 ("worst possible health") to 10 ("best possible health").

    Scores are transformed and calculated such that each scale score ranges from 0 to 100 where higher scores reflect a better quality of life.

    Measured: Baseline and 6 months

  4. Total Direct Costs of Care Associated With Secondary Hyperparathyroidism

    Direct medical costs to be calculated included outpatient visits, hospitalizations, pharmaceuticals, etc. However the data collected in this observational study was not enough to support this calculation.

    Measured: 6 months

  5. Total Indirect Costs of Care Associated With Secondary Hyperparathyroidism

    Indirect costs were estimated by using the number of hours missed from work (absenteeism) multiplied by the average hourly labor cost, including wages and benefits, to calculate average lost productivity costs due to absenteeism during the preceding 7 days.

    Hours missed from work were assessed using the Work Productivity and Activity Impairment Questionnaire: General Health (WPAI-GH) questionnaire, in which respondents answer 6 questions related to work productivity and impairment.

    Unit costs were taken from official sources (Statistics Sweden, www.scb.se) and published literature.

    Measured: 6 months

  6. Number of Participants Using Concomitant Medications at Baseline

    Measured: Baseline

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Feb 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Change From Baseline in Intact Parathyroid Hormone at 6 Months (time frame: Baseline and 6 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Feb 2014.
