Study groupRoleWhat they receive
CinacalcetExperimentalCinacalcet was administered orally at a starting dose of 30 mg/day for 23 weeks. Possible sequential doses during the study were 30, 60, 90, 120, and 180 mg. Dose escalation of cinacalcet occurred if the intact parathyroid hormone (iPTH) level from the previous study visit was > 31.8 pmol/L (300 pg/mL) unless the participant had either reached the maximum dose (180 mg/day), the serum corrected total calcium was < 2.1 mmol/L (8.4 mg/dL), or the participant experienced an adverse event that precluded a dose increase.

What is being measured

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

  1. Number of Participants With a Mean Intact Parathyroid Hormone Value Between 150 and 300 pg/mL and a Calcium - Phosphorus Product Value < 55 mg^2/dL^2

    The National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF K/DOQI) recommends that treatment interventions to control parathyroid hormone should not result in significant elevation of calcium - phosphorus product (Ca x P; a derived value calculated from serum calcium and phosphorus levels). The primary objective of the study was to assess the simultaneous achievement of NKF K/DOQI targets of intact parathyroid hormone (iPTH) greater than or equal to 15.9 pmol/L and less than or equal to 31.8 pmol/L (150 - 300 pg/mL) and a Ca x P value < 4.44 mmol^2/L^2 (55 mg^2/dL^2) during the effectiveness assessment phase.

    Measured: Weeks 17 to 23

Secondary outcomes (5)
  1. Number of Participants Who Achieved a Mean iPTH Value Between 150 and 300 pg/mL

    Number of participants who achieved a mean intact Parathyroid Hormone (iPTH) value greater than or equal to 15.9 and less than or equal to 31.8 pmol/L (150 - 300 pg/mL) during the effectiveness assessment phase.

    Measured: Weeks 17 to 23

  2. Number of Participants Who Achieved a Mean Ca x P Value < 4.44 mmol^2/L^2 (55 mg^2/dL^2)

    The number of participants who achieved a mean serum calcium x phosphorus (Ca x P) value < 4.44 mmol^2/L^2 (55 mg^2/dL^2) during the effectiveness assessment phase. The calcium - phosphorus product is a derived value calculated from serum calcium and phosphorus levels.

    Measured: Weeks 17 to 23

  3. Number of Participants Who Achieved a Mean Calcium Value ≥ 2.1 and ≤ 2.37 mmol/L

    The number of participants who achieved a mean corrected serum calcium (Ca) value ≥ 2.1 and ≤ 2.37 mmol/L (8.4 to 9.5 mg/dL) during the effectiveness assessment phase.

    Measured: Weeks 17 to 23

  4. Number of Participants Who Achieved a Mean Phosphorus Value ≥ 1.13 and ≤ 1.78 mmol/L

    The number of participants who achieved a mean serum phosphorus value ≥ 1.13 and ≤ 1.78 mmol/L (3.5 to 5.5 mg/dL) during the effectiveness assessment phase.

    Measured: Weeks 17 to 23

  5. Number of Participants Who Achieved a Mean CRP < 0.6 mg/dL

    The number of participants who achieved a mean C-reactive protein (CRP) level of < 0.6 mg/dL during the effectiveness assessment phase.

    Measured: Weeks 17 to 23

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Cinacalcet in people with Anemia and Secondary Hyperparathyroidism, run by Amgen.

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 7 inclusion and 11 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 24 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.

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 13 Jul 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?

Number of Participants With a Mean Intact Parathyroid Hormone Value Between 150 and 300 pg/mL and a Calcium - Phosphorus Product Value < 55 mg^2/dL^2 (time frame: Weeks 17 to 23). 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 24 Apr 2013.
