What is being measured

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

  1. Flow Mediated Vasodilation

    Using ultrasound, percent change in brachial artery diameter is measured in response to an increase in shear stress from a tightened blood pressure cuff, which causes endothelium-dependent dilatation.

    Measured: Baseline

  2. Flow Mediated Vasodilation

    Using ultrasound, percent change in brachial artery diameter is measured in response to an increase in shear stress from a tightened blood pressure cuff, which causes endothelium-dependent dilatation.

    Measured: 12 Weeks post-randomization

  3. Nitroglycerin Induced Dilation

    Using ultrasound, images are taken pre- and post-vasodilation of the brachial artery induced with a 0.4mg tablet of NTG.

    Measured: Baseline

  4. Nitroglycerine Induced Vasodilation

    Using ultrasound, images are taken pre- and post-vasodilation of the brachial artery induced with a 0.4mg tablet of NTG.

    Measured: 12 Weeks post-randomization

  5. Skin Blood Flow Before and After Iontophoresis With Acetylcholine and Sodium Nitroprusside

    Laser doppler imaging is used to measure microcirculatory changes pre- and post-iontophoresis of acetylcholine and sodium nitroprusside.

    Measured: Baseline

  6. Skin Blood Flow Before and After Iontophoresis With Acetylcholine and Sodium Nitroprusside

    Laser doppler imaging is used to measure microcirculatory changes pre- and post-iontophoresis of acetylcholine (Ach) and sodium nitroprusside (NaNP).

    Measured: 12 Weeks post-randomization

Questions about this trial

What is this clinical trial studying?

A study testing Aliskiren in people with Diabetes Type 2, run by Beth Israel Deaconess Medical Center 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 51 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 28 Mar 2017. 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. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Feb 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?

Flow Mediated Vasodilation (time frame: Baseline). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01165983, which also lists 1 linked publication.

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 28 Mar 2017.
