What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Paricalcitol injectionDrug

    Also called ABT-358, paricalcitol, Zemplar

    Most recent iPTH level in pg/mL divided by 100 = dose in mcg; dose is rounded down to nearest mcg and administered 3x weekly

  • Paricalcitol capsulesDrug

    Also called ABT-358, paricalcitol, Zemplar

    Most recent iPTH level in pg/mL divided by 80 = dose in mcg; dose is rounded down to nearest mcg and administered 3x weekly

What is being measured

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

  1. Proportion of Subjects Who Achieve at Least a 50% Reduction in iPTH Compared to Baseline Level

    Number of participants who achieved at least a 50% reduction in intact parathyroid hormone (iPTH) compared to the baseline level.

    Measured: 24 weeks

Secondary outcomes (5)
  1. Analysis of Episodes of Hypercalcemia (> 11.5 mg/dL), Hyperphosphatemia (> 7.0 mg/dL) and Elevations of Calcium x Phosphorus Product (> 75)

    Number of participants with hypercalcemia (calcium levels greater than 11.5 mg/dL), hyperphosphatemia (phosphorus levels greater than 7.0 mg/dL), or calcium x phosphorus product levels greater than 75.

    Measured: 24 Weeks

  2. Proportion of Subjects Who Achieve an iPTH <300 pg/mL

    Number of participants who achieved an intact parathyroid hormone (iPTH) level of less than 300 pg/mL.

    Measured: 24 weeks

  3. Time Required to Achieve: (1) a Reduction in iPTH Less Than <300 pg/mL;(2) a 50% Reduction in iPTH Compared to the Baseline Level; and (3) Either a Reduction in iPTH Less Than <300 pg/mL or a 50% Reduction in iPTH Compared to the Baseline Level

    Number of days required to achieve a reduction in intact parathyroid hormone (iPTH) to less than 300 pg/mL, a reduction in iPTH of greater than or equal to 50%, or either a reduction in iPTH to less than 300 pg/mL or a reduction in iPTH of greater than or equal to 50%.

    Measured: 24 weeks

  4. Duration of Response to Treatment

    Time in days between 2 consecutive visits with a reduction in intact parathyroid hormone (iPTH) of greater than or equal to 50% from the baseline visit.

    Measured: 24 weeks

  5. Health-related Quality of Life With Paricalcitol Injection or Oral Treatment

    Analysis of the differences before and after 24 weeks of treatment in various quality of life measurements for participants on hemodialysis receiving paricalcitol injection and participants on peritoneal dialysis receiving paricalcitol capsules.

    Measured: Baseline and 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Paricalcitol injection and Paricalcitol capsules in people with Secondary Hyperparathyroidism and Dialysis, run by Abbott at 12 sites in Mexico.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 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 25 Oct 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in Mexico. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Oct 2011). 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of Subjects Who Achieve at Least a 50% Reduction in iPTH Compared to Baseline Level (time frame: 24 weeks). 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 25 Oct 2011.
