Targeting Inflammation Using Salsalate in CardioVascular Disease

• Status: Completed
• Trial end date: 2016-07-01
• Target enrollment: 0
• Participant gender: All

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.

Criteria

Inclusion Criteria:

Eligibility will be based upon the presence of established coronary artery disease including

• 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:

1. Transient cavity dilation

2. More than one vascular territory involved with reversible defect (multiple defects)

3. Reversible defects involving the anterior wall, septum or apex (LAD territory)

Exclusions based on echocardiography imaging:

1. More than one vascular territory involved with inducible wall motion abnormalities (multiple defects)

2. 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:

1. aged 21- 75 years inclusive,

2. 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)

4. 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],

5. have liver function (ALT, AST) < 3 times upper limits of normal),

6. normal thyroid function (on stable dose replacement therapy is acceptable),

7. 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

8. 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.

Exclusion Criteria:

1. Unstable angina (increase in frequency or severity of anginal episodes or development of chest pain at rest)

2. significant obstructive disease (≥ 70%) in left main coronary artery, ostial LAD or three-vessel disease by MDCTA

3. Significant heart failure (NYHA class III and IV)

4. Current atrial fibrillation or Wolf-Parkinson-White (WPW) syndrome

5. Allergy to beta-blocker in subjects with resting heart rate > 65 bpm

6. Systolic blood pressure > 160 mm Hg

7. Diastolic BP > 100 mm Hg

8. Persons with allergies to contrast material

9. History of asthma if unable to tolerate beta blocker

10. Allergy to iodinated contrast material or shellfish

11. Allergy to nitroglycerin

12. BMI > 35 kg/m2 if female and > 40 kg/m2 if male

13. Body weight > 350 lbs

14. Use of drugs for weight loss [e.g. Xenical (orlistat), Meridia (sibutramine), Acutrim (phenylpropanolamine) or similar over-the counter medications] within three months of screening

15. Surgery within 30 days of screening

16. History of acquired immune deficiency syndrome or human immunodeficiency virus (HIV)
