Targeting Inflammation Using Salsalate in CardioVascular Disease

Study Overview
=================
Brief Summary
-----------------
The hypothesis is that western lifestyle, with sedentary behaviors and caloric excess promote a chronic, subacute inflammatory state that participates in the development and progression of atherosclerosis. We will evaluate the effects of targeting inflammation using the anti-inflammatory drug salsalate, compared to placebo, on coronary artery plaque volume assessed by multi-detector computed tomographic angiography (MDCTA). The TINSAL-CVD study is a randomized, double-masked, placebo-controlled, 2 arm, clinical trial. The purpose of the study is to compare the effect of salsalate or placebo on sub-acute inflammation and coronary plaque, in people with cardiovascular disease. Participants are randomized to active intervention (salsalate) or placebo interventions for a period of 30 months. The primary endpoint is change in plaque volume in the coronary arteries assessed by MDCTA from baseline to 30 months.

Detailed Description
-----------------
OBJECTIVE: To determine whether targeting inflammation using salsalate compared with placebo reduces progression of noncalcified coronary artery plaque. DESIGN, SETTING, AND PARTICIPANTS: In the Targeting Inflammation Using Salsalate in Cardiovascular Disease (TINSAL-CVD) trial participants were randomly assigned to 30 months of salsalate or placebo in addition to standard, guideline-based therapies. Randomization was computerized and centrally allocated, with patients, health care professionals, and researchers masked to treatment assignment. Participants were overweight and obese statin-using patients with established, stable coronary heart disease. INTERVENTIONS: Salsalate (3.5 g/d) or placebo orally over 30 months. MAIN OUTCOMES AND MEASURES: The primary outcome was progression of noncalcified coronary artery plaque assessed by multidetector computed tomographic angiography. Secondary outcomes were other measures of safety and efficacy.

Inclusion Criteria: Eligibility will be based upon the presence of established coronary artery disease including previous myocardial infarction (≥6 months ago), or previous coronary bypass surgery (> 12 months ago), or stable angina, or significant non-calcified plaque in at least one coronary artery, or abnormal exercise tolerance test or an area of reversible ischemia on nuclear imaging study or pharmacologic stress, with subsequent revascularization, or angioplasty, or abnormal exercise treadmill stress test with or without nuclear imaging or echocardiography with the following exclusions: Exclusions based on nuclear imaging: Transient cavity dilation More than one vascular territory involved with reversible defect (multiple defects) Reversible defects involving the anterior wall, septum or apex (LAD territory) Exclusions based on echocardiography imaging: More than one vascular territory involved with inducible wall motion abnormalities (multiple defects) Inducible wall motion abnormalities involving the anterior wall, septum or apex (LAD territory) Subjects should be at list 6 months after a myocardial infarction and/or revascularization procedure to be eligible. In addition, subjects must be: aged 21- 75 years inclusive, BMI ≥ 27 kg/m2 and ≤ 35 kg/m2 if female and ≤ 40 kg/m2 if male (a BMI ≥24.5 for subjects from Asian origin) on a stable dose of an HMG CoA reductase inhibitor (statin) for 1 month at screening or unable to tolerate a statin, have normal renal function, (note estimated creatinine clearance calculated using Cockcroft-Gault (CG) equation ≥60 at screening [eCrCLCG (ml/min) = [(140 - age) x weight (kg)]/[SCr(mg/dl) x 72] x [0.85 if female], have liver function (ALT, AST) < 3 times upper limits of normal), normal thyroid function (on stable dose replacement therapy is acceptable), if women are of child bearing potential they must have a pregnancy test prior to the CT angio and use contraception for the remainder of the study patients with T2D must have a fasting glucose of ≤ 200 mg/dl at screening and cannot be treated with thiazolidinedione class agents or insulin or Extendin-4 (Byetta) therapy. Subjects must be willing to have at least three visits at the Beth Israel-Deaconess Medical Center/Joslin Diabetes Center with a baseline and a 30-month follow-up series of imaging studies including CT angiography of the coronary arteries and imaging of the aorta, abdominal adiposity and liver, and interim visit at 1 year.
