About this study
Official title: Targeting Inflammation to Treat Cardiovascular Aging in Humans (TIVA Study)
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the United States with older age being a primary risk factor. The number of adults greater than age 65 years will almost double to 70 million by 2030, therefore identifying therapeutic strategies for treating or preventing age-related disorders in humans is of major biomedical importance. Cardiovascular aging, defined as a reduction in vascular and cardiac functions with normal aging, occurs even in the absence of CVD risk factors and overt CVD. A key feature of cardiovascular aging is stiffening of the large elastic central arteries such as the aorta. This is important because aortic stiffness directly contributes to clinical problems such as increased blood pressure, reduced blood flow to the heart muscle, and thickening of the heart muscle. Therefore, these clinical consequences are hypothesized to mediate a substantial proportion of the increase in CVD risk in older adults. However, effective drug treatments for aortic stiffness are not currently available and the biological reasons (mechanisms) involved in causing aortic stiffening remain undefined. In addition, the inability of smaller blood vessels to relax, impairment of the heart to relax during the filling phase of the heart cycle (i.e., diastole), and increased blood pressure variability, have all been linked to aortic stiffness. Furthermore, chronic low-grade inflammation with advancing age has been proposed to be a common mechanistic link (i.e., biological reason) between these reductions in cardiovascular function in older adults. Therefore, the investigators propose that inflammation could be a novel therapeutic target to treat cardiovascular aging in older adults. Our central hypothesis is that inflammation mediates the age-related deterioration in cardiovascular functions observed with advancing age through the development of oxidative stress (i.e., imbalance between damaging oxygen free radicals vs. protective antioxidants). Our hypothesis predicts that chronic inhibition of inflammation with Salsalate, an FDA-approved anti-inflammatory drug similar to aspirin that is used to treat rheumatoid arthritis pain and known to inhibit the 'master' regulator of inflammation in the cell (i.e., nuclear factor kappa B), will improve cardiovascular function in older adults. In addition, the investigators hypothesize that the mechanism for the improvement in cardiovascular function during inhibition of inflammation will be by suppressing oxidative stress. To test our hypothesis, the investigators will randomize older healthy adults (age 50-79 years) to 3 g/day of salsalate or placebo (i.e., pill with inactive substance) pills for 4 weeks and have cardiovascular function measured at baseline and again after 4 weeks.
Read the detailed description
Aim 1: To measure aortic wall stiffness and circulating biomarkers of oxidative stress during both acute (IV) intravenous infusions of saline and then the antioxidant vitamin C at baseline and after 4 weeks of salsalate or placebo in healthy older adults. Hypothesis 1: Inhibition of inflammation in older adults will decrease aortic wall stiffness in part by reductions in oxidative stress.
Aim 2: To measure brachial artery endothelium-dependent vasodilation (EDV) and circulating markers of oxidative stress during acute intravenous infusions of saline and then the vitamin C at baseline and after 4 weeks of salsalate or placebo in healthy older adults. Hypothesis 2: Inhibition of inflammation in older adults will improve vascular endothelial vasodilatory function in older adults in part by reductions in oxidative stress.
Aim 3: To measure left ventricular (LV) diastolic relaxation and filling dynamics and circulating markers of oxidative stress during both acute intravenous infusions of saline and then vitamin C at baseline and after 4 weeks of Salsalate or placebo in healthy older adults. Hypothesis 3: Inhibition of inflammation in older adults will improve LV diastolic function in part by reductions in oxidative stress.
Exploratory Aim: To measure 24-hour pressure variability and short-term baroreflex sensitivity before and after 4 weeks of oral Salsalate or placebo treatment in older adults. Exploratory hypothesis: Inhibition of inflammation in older adults will improve cardiovascular autonomic dysregulation in older healthy adults.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Salsalate in people with Vascular Stiffness and Endothelial Dysfunction, run by Gary L. Pierce 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 10 inclusion and 28 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 31 May 2018. 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.
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 31 May 2018). 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?
Carotid-femoral Pulse Wave Velocity (CFPWV) (time frame: Change in CFPWV from baseline at 4 weeks). 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 NCT01775865, which also lists 8 linked publications.
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 31 May 2018.
