What is being measured
The primary outcome is the main question the study is designed to answer.
The percentage of subjects that reach the JNC diabetic hypertensive BP goal of <130/80 will be assessed at Week 0 (Visit 2-Randomization), Week 5 (Visit 3), Week 9 (Visit 4), Week 15 (Visit 5) and Week 20 (Visit 6 - Final Evaluation).
Secondary outcomes (1)
Percentage of subjects at SBP goal of <130 mmHg and DBP goal of <80mmHg; change from baseline blood pressures (SBP and DBP); percentage of subjects with SBP >160mmHg and/or DBP >100mmHg at Visits 2, 3, 4, 5, 6.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
The percentage of subjects that reach the JNC diabetic hypertensive BP goal of <130/80 will be assessed at Week 0 (Visit 2-Randomization), Week 5 (Visit 3), Week 9 (Visit 4), Week 15 (Visit 5) and Week 20 (Visit 6 - Final Evaluation).. 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 28 Jan 2021.
