About this study

Official title: A Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy and Safety of Using Cinacalcet to Correct Hypercalcemia in Renal Transplant Recipients With Autonomous Hyperparathyroidism

Hyperparathyroidism (HPT) is common in people with a kidney transplant. Patients with HPT often have high parathyroid hormone (PTH) levels and may have large parathyroid glands in the neck. Patients with HPT can develop bone disease (osteodystrophy). This bone disease can cause bone pain, fractures, and poor formation of red blood cells. Other problems from HPT may include increases in blood levels of calcium (hypercalcemia) and low blood levels of phosphorus (hypophosphatemia). The high calcium levels may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), heart and lung problems or kidney transplant dysfunction (worsening of kidney transplant function). The purpose of this study is to evaluate the effects of cinacalcet (Sensipar/Mimpara) on high calcium levels in the blood in patients with HPT after a kidney transplant.

What participants receive

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

  • CinacalcetDrug

    Also called Mimpara, Sensipar

    Possible sequential doses are 30, 60, 90, 120, and 180 mg.

  • PlaceboDrug

    Administered orally following the same dosing regimen as the experimental arm.

Study groups in NCT00975000
Study groupRoleWhat they receive
CinacalcetExperimentalParticipants received cinacalcet at a starting dose of 30 mg orally once daily for 52 weeks. Cinacalcet dose was titrated every 4 weeks during the dose-titration phase and during study visits in the maintenance phase based on intact parthyroid hormone (iPTH) values, corrected total serum calcium values, and safety assessments.
Receives: Drug: Cinacalcet
PlaceboPlacebo comparatorParticipants received placebo orally once daily for 52 weeks.
Receives: Drug: Placebo

What is being measured

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

    Measured: Weeks 21 to 26 (EAP)

Secondary outcomes (8)
  1. Percent Change From Baseline to Week 52 in Bone Mineral Density at the Femoral Neck

    Bone mineral density (BMD) was measured using dual X-ray absorptiometry (DXA).

    Measured: Baseline and Week 52

  2. Change From Baseline to the EAP in Mean Serum Phosphorus

    Measured: Baseline and the EAP (mean of Weeks 22, 24, and 26)

  3. Change From Baseline to Week 52 in eGFR

    eGFR was calculated using the Modification of Diet in Renal Disease (MDRD) formula.

    Measured: Baseline and Week 52

  4. Change From Baseline to the EAP in Corrected Total Calcium

    Measured: Baseline and the EAP (mean of Weeks 22, 24, and 26)

  5. Change From Baseline to the EAP in Intact Parathyroid Hormone (iPTH)

    Measured: Baseline and the EAP (mean of Weeks 22, 24, and 26)

  6. Change From Baseline to the EAP in Urine Phosphorus

    Measured: Baseline and the EAP (mean of Weeks 22, 24, and 26)

  7. Percentage of Participants With a Parathyroidectomy

    Measured: 56 weeks

  8. Time to Parathyroidectomy

    Measured: 56 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Cinacalcet in people with Chronic Allograft Nephropathy and Chronic Kidney Disease, run by Amgen at 51 sites in 11 countries.

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 6 inclusion and 9 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 17 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 51 sites in United States, Canada, France, Poland, Spain and 6 more countries. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 29 Jan 2016). 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?

Percentage of Participants With a Mean Corrected Total Serum Calcium Value < 10.2 mg/dL (2.55 mmol/L) During the Efficacy Assessment Phase (EAP) (time frame: Weeks 21 to 26 (EAP)). 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 17 Oct 2018.
