Investigation of Vascular Relaxing Effects of Candesartan and Pioglitazone.
A study testing Pioglitazone (drug) and/or candesartan (drug) in people with Healthy Subjects, run by Technische Universität Dresden at 1 site in Germany.
Trial summary
The study is designed to test the hypothesis in healthy subjects that candesartan and pioglitazone provide additional vascular relaxing or modulating effects in addition to their blood-pressure and blood glucose level reducing ability, respectively. Read more about this study

About this study
Official title: Characterization of Vascular Effects of Candesartan and Pioglitazone.
The study is designed to test the hypothesis in healthy subjects that candesartan and pioglitazone provide additional vascular relaxing or modulating effects in addition to their blood-pressure and blood glucose level reducing ability, respectively.
Read the detailed description
The aim of the study is to investigate the effect of oral candesartan and/ or rosiglitazone therapy on the vascular responsiveness of different vasoactive compounds (angiotensin II, insulin, histamine and glyceroltrinitrate) in healthy subjects. Pioglitazone will be given orally (4 weeks 30mg/d, titrated to 45 mg/d for another 4 weeks). Candesartan will be given orally (4 weeks 8mg/d, titrated to 16 mg/d for another 4 weeks) as treatment. Every subject will receive intravenous stimulation with phenylephrine, angiotensin II, histamine, insulin and glyceroltrinitrate before and after an 8 weeks treatment interval with study medication or placebo. In addition, pulse wave velocity will me measured non-invasively before and after treatment.

Questions about this trial
What is this clinical trial studying?
A study testing Pioglitazone (drug) and/or candesartan (drug) in people with Healthy Subjects, run by Technische Universität Dresden 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 5 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: finished, as of the sponsor's last update on 13 Sep 2006. 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.
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?
Vascular reactivity. 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 13 Sep 2006.
