Trial summary

The purpose of this study is to evaluate the safety and efficacy of the blood pressure medication, aliskiren, in heart transplant patients. In terms of safety, the investigators will evaluate the blood levels of aliskiren and determine if aliskiren alters the blood levels of the anti-rejection medication… Read more about this study

About this study

The purpose of this study is to evaluate the safety and efficacy of the blood pressure medication, aliskiren, in heart transplant patients. In terms of safety, the investigators will evaluate the blood levels of aliskiren and determine if aliskiren alters the blood levels of the anti-rejection medication, cyclosporine, in these patients. In terms of efficacy, the investigators will determine how well aliskiren lowers blood pressure in heart transplant patients.

Read the detailed description

Hypertension is a major complication following cardiac transplantation, with a prevalence of 93% at 5 years post-transplant. Post-cardiac transplant hypertension is due to multiple factors such as use of cyclosporine, chronic kidney disease, and denervation. Hypertension in this population is difficult to treat, and most patients require therapy with multiple antihypertensive agents in order to achieve adequate blood pressure control. Aliskiren, a direct renin inhibitor, is a novel antihypertensive agent with a unique mechanism of action and potent blood pressure-lowering effects. As such, aliskiren is an attractive treatment option for post-cardiac transplant hypertension. This study will characterize the pharmacokinetic drug-drug interaction profile, pharmacodynamics, and safety of aliskiren 75 mg daily (low-dose) and 150 mg daily, when given in combination with cyclosporine, in cardiac transplant patients.

What is being measured

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

  1. Dose-normalized Cyclosporine Area Under the Plasma Concentration-time Curve (AUC)

    The study was stopped due to difficulty finding patients who met the strict inclusion criteria. Only one patient was started on the study drug. as a result we did not analyze any cyclosporine PK (e.g.(AUCs) for this study.

    Measured: 7 days, 14 days, 30 days (End of Study)

Secondary outcomes (2)
  1. Aliskiren Plasma Concentrations

    Maximum plasma concentration; area under the concentration-time curve, half-life, oral clearance

    The study was stopped due to difficulty finding patients who met the strict inclusion criteria. Only one patient was started on the study drug. as a result we did not analyze any PK (e.g.(AUCs) for this study.

    Measured: 2 weeks

  2. Blood Pressure

    The study was stopped due to difficulty finding patients who met the strict inclusion criteria. Only one patient was started on the study drug. as a result we did not analyze any blood pressure for this study.

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Aliskiren in people with Hypertension and Cardiac Transplantation, run by University of Colorado, Denver at 1 site in United States.

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 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: stopped early, as of the sponsor's last update on 29 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 18 Aug 2015). 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?

Dose-normalized Cyclosporine Area Under the Plasma Concentration-time Curve (AUC) (time frame: 7 days, 14 days, 30 days (End of Study)). 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 29 Jun 2018.
