What is being measured

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

    The effect of co-administration of sildenafil on the pharmacokinetics of LCZ696 (analytes of LCZ696: AHU377, LBQ657 and valsartan) was assessed. Blood samples were collected at pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hours post-dose from day 1 to day 7, 24 hours post-dose from day 7, and day 8 at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hours post-dose. AUC is a mathematically-derived value from all measurements. AUC is a measure of the area under the curve that is obtained from plotting the plasma concentration by time point. All time-points were used to derive the single PK parameters.

    Measured: From pre-dose on day 1 until 12 hours post dose on day 8

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing LCZ696 and Sildenafil in people with Mild to Moderate Hypertension, run by Novartis Pharmaceuticals at 1 site in Germany.

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 2 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 7 Oct 2015. 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 Germany. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 28 Sep 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?

Area Under the Plasma Concentration-time Curve From Time Zero to the End of the Dosing Interval (AUCtau) of LCZ696 Analytes (time frame: From pre-dose on day 1 until 12 hours post dose on day 8). The study lists 9 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 NCT01601470, 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 7 Oct 2015.
