Study groups in NCT00819767
Study groupRoleWhat they receive
AliskirenExperimentalFor the first week of the 8 week treatment period, patients received aliskiren 150 mg, placebo to aliskiren, and 2 capsules of placebo to valsartan. For the remaining 7 weeks of the study, patients received aliskiren 300 mg (two 150 mg tablets) and 2 capsules of placebo to valsartan. The tablets and capsules (2 of each) were taken orally once daily each morning. To evaluate a missed dose, the last dose of medication was administered at the clinic, and the patient was scheduled to return 2 days later for exercise testing (8 weeks + 2 days).

What is being measured

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

  1. Change in Resting vs. Peak Heart Rate Systolic Blood Pressure (SBP) From Baseline to Week 8 After a Missed Dose

    The difference in resting vs. peak (85% of maximal predicted) heart rate (HR) SBP was calculated by measuring SBP before and during exercise on a standardized treadmill test, conducted according to the Bruce Protocol. Treadmill speed and incline were increased every 3 minutes until the patient was exhausted or peak HR was reached. The SBP at rest vs peak HR was recorded at Baseline and at Week 8 + 2 days (24-hrs after a missed dose); the change in rest vs. peak SBP between these timepoints is reported. The analysis included the rest to peak increase in SBP at baseline as a covariate.

    Measured: Baseline and Week 8 + 2 days (48-hours after the last dose; 24 hours after a missed dose). Blood Pressure measurements were taken at rest and at peak heart rate at both timepoints.

Secondary outcomes (2)
  1. Change in Resting vs. Peak Heart Rate Systolic Blood Pressure (SBP) From Baseline to Week 8

    The difference in resting vs. peak (85% of the maximal predicted) heart rate (HR) SBP was calculated by measuring SBP before and during exercise on a standardized treadmill test, conducted according to the Bruce Protocol. Treadmill speed and incline were increased every 3 minutes until the patient was exhausted or peak HR was reached. The SBP at rest vs peak HR was recorded at Baseline and at Week 8 (end of active treatment); the change in SBP between these timepoints is reported. The analysis included the rest to peak increase in SBP at baseline as a covariate.

    Measured: Baseline and Week 8 (end of active treatment). Blood Pressure measurements were taken at rest and at peak heart rate at both timepoints.

  2. Change in Resting vs. Peak Heart Rate Systolic Blood Pressure (SBP) From Week 8 (End of Active Treatment) to 24-hours After a Missed Dose

    The difference in resting vs. peak (85% of maximal predicted) heart rate (HR) SBP was calculated by measuring SBP before and during exercise on a standardized treadmill test, conducted according to the Bruce Protocol. The SBP at rest vs peak HR was recorded at Week 8 (end of active treatment) and Week 8 + 2 days (48-hrs after last dose; 24-hrs after missed dose); the change in rest vs. peak SBP between these timepoints is reported. The analysis included the rest to peak increase in SBP at baseline as a covariate.

    Measured: Week 8 (Last dose; end of active treatment) and Week 8 + 2 days (48-hours after the last dose; 24 hours after a missed dose). Blood Pressure measurements were taken at rest and at peak heart rate at both timepoints.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Aliskiren and Valsartan in people with Hypertension, run by Novartis at 8 sites in 4 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 2 inclusion and 4 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 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Hungary, Czechia, Singapore, United Kingdom. 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 Jun 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?

Change in Resting vs. Peak Heart Rate Systolic Blood Pressure (SBP) From Baseline to Week 8 After a Missed Dose (time frame: Baseline and Week 8 + 2 days (48-hours after the last dose; 24 hours after a missed dose). Blood Pressure measurements were taken at rest and at peak heart rate at both timepoints.). 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 NCT00819767, 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 Jun 2011.
