Brief summary:
Atherosclerotic disease, or hardening of the arteries, is characterized by the thickening of the arterial walls due to fatty deposits in wall and inflammation in the wall of arteries. High cholesterol, high blood pressure, diabetes, obesity and genetics play an important role in developing clinical symptoms of atherosclerosis disease. The complications of advanced atherosclerosis are chronic, slowly progressive and cumulative, resulting in heart attack, stroke and/or death and blockage of arteries.

This study is being done to assess the effectiveness of Spironolactone therapy to slow down the worsening of atherosclerotic disease (hardening of the arteries) in aorta (this is a large vessel coming out of your heart) compared to placebo (look alike sugar pill). This will be checked by comparing before and after therapy magnetic resonance imaging (MRI) pictures of your aortic wall.

Spironolactone is an FDA approved drug used to treat heart failure and in the management of hypertension (high blood pressure), but in this study it is used for another unapproved reason. In this study, we would like to evaluate the effects of Spironolactone in people with diabetes and atherosclerotic disease.

SUMMARY  
Atherosclerosis is the leading cause of morbidity and mortality in Type II diabetes. A cell type called the 
monocyte/macrophage is critical to development and complications of atherosclerosis. This project will 
evaluate the effectiveness of a medication called Spironolactone in preventing atherosclerosis in Type II 
diabetes through its effects on cells such as the monocyte. Spironolactone has been demonstrated to be 
effective for the treatment of patients after a heart attack and stroke. We will evaluate the impact of 
Spironolactone in reducing atherosclerosis plaque and additionally evaluate its potential in changing 
inflammation. We envision that our strategy of simultaneously probing effect of a drug combined with 
analysis of mechanisms of action and predictive response will likely provide key information with which 
to design hard event (heart attack, stroke etc.) based trials. 
BACKGROUND  
Pharmacological studies over > 20 years have defined the importance of the mineralocorticoid receptor 
(MR) in hypertension and heart failure. Large-scale clinical trials have validated the use of MR 
antagonists in the management of patients with heart failure (RALES, EMPHASIS) and post myocardial 
infarction (EPHESUS)1-4 . Recent studies suggest that MR may link metabolic dysregulation with 
susceptibility to type II diabetes (T2DM) and atherosclerosis5-12 . MR is an ancient member of the 51-
member, steroid-thyroid-retinoid receptor family. In response to ligand binding, MR undergoes 
conformational changes and is translocated to the nucleus where it binds to response elements in 
promoters, increasing transcription of target genes 13,14 . Although effects of MR activation have been 
attributed to aldosterone, mechanisms independent of aldosterone have been suggested and play a role 
in promoting inflammation, fibrosis and target organ damage15-18 .  
Cardiovascular Effects of MR Activation: MR is widely expressed in the cardiovascular system 19-22 and 
is a major determinant of endothelial function, smooth muscle tone, vascular remodeling, fibrosis and 
blood pressure (BP)23-36 . In vitro, animal, and human data support a role for MR activation in 
promoting vascular oxidative stress, inflammation, proliferation, migration, vasoconstriction, vascular 
remodeling and fibrosis (FIG. 2) 5,28,31,36-44 . Similarly, MR antagonism is anti-inflammatory and 
antifibrotic with evidence in humans indicating reversal of endothelial dysfunction, diastolic dysfunction 
and vascular stiffness45-49 . 


 
 
MR Activation Links Insulin Resistance (IR), Inflammation and Atherosclerosis: A number of reviews 
have already detailed in-vitro, experimental and human evidence linking aldosterone/MR activation 
with IR but is briefly summarized here.5-8,50-52 The visceral adipose renin-angiotensin-aldosterone 
(RAS) system synthesizes aldosterone, expresses MR, and predicts IR in both humans and animal 
models7,52,53 . MR expression on macrophages could potentially play a pro-inflammatory role in 
tissues such as adipose and vasculature.54-57 MR blockade/deletion has been shown in both 
experimental and human studies to ameliorate IR 58-60 . MR activation may affect IR through multiple 
mechanisms that include attenuation of insulin signaling in the heart, vasculature, and skeletal muscle. 
This may include impairment of expression of insulin receptor and substrate, decreased GLUT4 
expression, abnormal phosphorylation of IRS, and activation of multiple stress kinases downstream of 
insulin receptor/IRS (leading to attenuation of insulin signaling)61-64 . MR activation also promotes 
hepatic oxidative stress, gluconeogenesis and enhances hyperglycemia 65 . Recently, MR activation has 
been shown to promote lipid storage in brown adipose and inhibit UCP1 expression 66,67 . Consistent 
with these roles, MR antagonism in humans improves IR 58-60,68 . Relevant to this proposal we have 
provided evidence for a role for MR in pro-inflammatory macrophage phenotype and reduction in 
atherosclerosis in animal models. 
Role for the MR in Inflammation: Studies by Lumeng (co-investigator) and Chawla have provided the 
conceptual framework for understanding macrophage polarization state in the context of insulin 
resistance, obesity, and atherosclerosis 69-74 . Macrophages display heterogeneity of function 
depending on their micro-environment 75,76 . Th1 signals such as LPS/IFN result in “classical 
activation” leading to iNOS mediated NO production and synthesis of TNF- and IL-6 77 . In contrast, an 
alternatively activated (A) state of macrophage is generated upon exposure to IL-4/IL-13, which are 
generally implicated in resolution of inflammation and tissue repair 78-81 . Analysis of markers of A 
have provided a remarkably conserved and stereotypic signature of genes corroborated by recent 


genome-wide analysis of macrophage function.82 Although A has been implicated in a range of 
physiologic and pathological processes, including inflammation, repair, and metabolic function, its role 
in atherosclerosis continues to evolve. PPAR activation of macrophages by glitazones both in vitro and 
in vivo in patients with atherosclerosis, induces A while deletion or antagonism (in mice) contributes 
to a classically activated phenotype 70,83,84 . In contrast to the function of PPAR, MR activation 
potentiates classical activation while deletion of MR or antagonism results in A 85 . The relative 
contribution and relevance of A in atherosclerosis is not well studied. Studies in humans that provide 
insights on the role of A and factors that may modulate macrophage phenotype may provide novel 
insights in atherosclerosis. Recently microRNAs (miRNAs) via their role as regulators of gene networks 
may represent mediators of functional networks and phenotypes such as A and may provide insights 
into risk in atherosclerosis. We have provided important links between candidate miRs that play a role in 
macrophage A through MR. We propose studies to investigate this in a clinical trial of MR antagonism 
in patients with T2DM. 
Rationale for miRNA’s as Regulator of A and Marker(s) of Risk/Response: miRNAs hold the potential 
to modulate complex physiological/disease phenotypes and/or response to therapies by regulating 
entire functional networks. miRNAs are non-coding RNAs of 18–25 nucleotides that regulate multigene 
expression and modulate entire biologic pathways. It has been estimated that up to 1000 miRNAs are 
encoded by the human genome 86 . miRNAs are transcribed as precursors called primary miRNAs, which 
are processed to form mature miRNAs87 . Mature miRNAs recognize specific target mRNAs and induce 
gene silencing by mRNA degradation and/or inhibition of translation 86,87 . Assessment of miRNAs may 
provide insights into mechanisms of action/effect of therapies. In support of this, miRNAs are risk 
predictors in cancer and emerging studies suggest that miRNAs may predict risk in cardiovascular 
disease 88-93 . 
 
Preliminary Studies  
MR antagonism is associated with Improvements in Vascular Function and Plaque Burden: Proof-
ofconcept experiments from our group using two different MR antagonists (Eplerenone and 


Spironolactone) in two distinct models of atherosclerosis provide experimental/mechanistic basis for the 
proposed investigation. In the first model, New Zealand white male rabbits were fed 1% cholesterol 
chow (HL) or normal chow (NC) over 8 weeks to induce atherosclerosis and then randomized to receive 
Eplerenone or placebo (Epl10 mg/kg) for 6 additional weeks. Eplerenone normalized peak endothelium 
dependent relaxation while nitroglycerin responses were unaltered (data for nitroglycerin not shown) 
(FIG. 4). Since we and others have established the importance of NADPH derived superoxide inactivation 
of •NO in response to angiotensin II (AII) and aldosterone, we investigated these sources 94-98 . 
Treatment with Eplerenone reduced •O2 - in aorta. We then studied the effects of Eplerenone in high-
fat fed LDLR-/- model (Eplerenone 10 mg/kg for 12 weeks). Similar improvements in endothelial dilation 
in the LDLR-/- were seen (FIG 4). Epl reduced atherosclerosis and macrophage infiltration. These same 
data have been reproduced in the ApoE-/- by other groups 99,100 . In additional experiments, we have 
demonstrated that Eplerenone treatment prevents aldosterone induced thrombosis101 . 
Role of the MR in Control of Macrophage Polarization: In collaboration with Dr. Lumeng, we and others 
have shown that various pro-inflammatory insults including highfat feeding and air-pollution can result 
in a shift to an M1 phenotype 72,102-104 . Cytokines from an M1 polarized macrophage, such as TNFα 
and CCL-2 play an important role in potentiation of inflammation and insulin resistance. Usher and 
Lumeng et al have recently shown that peritoneal macrophages in mice could be rendered pro-
inflammatory via exposure to aldosterone, an effect prevented by Eplerenone but not the GR antagonist 
RU486 85 . Deletion of MR in myeloid cells recapitulated the effects of MR antagonism, by shifting 
phenotype to an alternately activated form concomitantly down regulating proinflammatory and pro-
fibrotic genes (TGFβ and PAI-1). IL-4, an inducer of Aϕ, synergized with macrophages lacking MR to 
display enhanced expression of Aϕ markers. In vivo the effects of myeloid deletion of MR reduced, 
aortic and cardiac macrophage recruitment, cardiac hypertrophy, fibrosis and fetal gene re-
programming in response to AII and L-NAME (model of MR activation) suggesting that myeloid MR was 
crucial to adverse cardiovascular remodeling 85 . Finally gene expression analysis revealed significant 
similarity between MR deletion and PPAR activation. 
Bioinformatic and in vitro assessment of miRNA regulation of NR3C2 (MR gene) in human monocytes: 
We first asked if NR3C2 is a target for miRNA regulation and investigated this using in-silico approaches. 
NR3C2 has one of the longest 3’-UTR’s in the RAS cascade and contains the highest number of predicted 
miRNA targets based on Targetscan 5.2 analysis indicating that it may be under intricate miRNA control. 
Fifteen miRNAs including 2 unique miRNA families (miR-30 and miR129) were identified that bound to 
11 distinct sites on the 3’-UTR. These miRNAs were then analyzed in 10 miRNA prediction algorithms 
(Diana, MicroInspector, Miranda, mirtarget2, mitarget, nbmirtar, pictar, pita, rna22, rnahybrid). miRNAs 
that were common to at least 5 different prediction algorithms were identified. Based on this analysis, 
we investigated the expression of miRNAs initially identified in-silico, in human monocytes and then 
investigated their regulation in monocytes derived from a cohort of patients with atherosclerosis 
(derivation cohort, n=10; mean age=65±6 years) using an expression array with >600 miRNAs 
(Nanostring Technologies. All patients in the derivation cohort were receiving ACEI/ARB/statin therapy 
and were compared to control subjects without risk factors for atherosclerosis (n=6 per group). We used 
a miRNA expression array (Nanostring Technologies, CA) that provides quantitative assessment of >600 
human miRs. miR’s regulated in atherosclerosis were defined as those that were highly regulated (p<10-
10 vs. control subjects). The data set was filtered for outliers and analyzed. The putative miRNAs that 
target NR3C2, are expressed in monocytes AND are downregulated in atherosclerosis. We then analyzed 


the relationship of miRNAs obtained in the derivation cohort, with aortic plaque measured by MRI. 
Correlation analysis with baseline atherosclerosis revealed that multiple miRs correlated with 
atherosclerosis plaque burden at baseline after adjustment of baseline covariates (age, gender, blood 
pressure and LDL cholesterol). This included 31 miRNAs involved in NR3C2 regulation (r2 =0.35) as well 
as several candidate miRs unrelated to MR expression (Down-regulated=miR-27, r 2=0.36; miR-125, r 
2=0.25; miR-124, r 2=0.20; miR-7 r 2=0.19; Up-regulated: miR-223. r 2=0.25; mir-126. r 2=0.22; miR-
1720, r 2=0.15. 
Regulation of NR3C2-3UTR Luciferase Reporter: NR3C2 3-UTR was cloned downstream of a mammalian 
promoter-luciferase system and co-transfected in HeLa cells with plasmids expressing pmiR-19b and 
pmiR-124 have shown that 124 but not 19b reduced luciferase activity by more than 50%105 . Studies 
examining other miRNAs in HeLa cells are currently ongoing in the laboratory. 
Assessment of Aortic Atherosclerosis at 3.0T MR using SPACE: We have described the implementation 
of a modified spin echo sequence T1W-SPACE and have successfully implemented this technique at both 
1.5T and 3.0T 106,107 . We have developed a customized tool-set for assessment of plaque area over 
the aorta.  
Plaque Progression over 9 months: In a recently concluded study in patients with established vascular 
disease on complete renin blockade with Aliskiren (ALPINE, n=37)108 . The results of this study 
demonstrated that aliskerin use on top of ACEI/ARB progresses atherosclerosis. These results are 
consistent with results of ALTITUDE published recently 109 . Interestingly one of the findings in the 
study was that aliskerin treatment resulted in decrease of miR-19a which we have shown to be 
important in upregulation of MR. This increase was particularly robust in those on ACEI/ARB therapy 
suggesting that this group could be potentially sensitive to the effects of MR blockade as they are 
overexpressing MR (product of NR3C2 gene). 
STUDY RATIONALE  
There are multiple innovative concepts in this trial. 1) There are currently no large trials of MR 
antagonism in patients with diabetic atherosclerosis and no trials that are investigating predictors of 
response. Our results will provide a basis for a definitive intervention trial. 2) Investigation of 
monocyte/macrophage polarization: The importance of monocyte/macrophage activation states in 
metabolic and cardiovascular disease is yet to be fully integrated into our understanding. Our 
preliminary studies and those by others support an important role for MR in A, but whether or not 
pharmacologic blockade of MR modifies monocyte inflammation in humans is unknown. 3) Investigation 
of miRNAs: Prior studies have shown that miRNAs are involved in monocyte differentiation and 
inflammatory function 110,111 . Our approach to incorporate miRNA analysis to predict response is 
innovative and is based on preliminary data suggesting that several candidate miRNAs regulated MR 
expression and A. 3) MRI Approaches in Aortic Imaging: MRI approaches can track serial changes in 
atherosclerosis 112-117 . Prior MRI approaches have assessed the carotid or a limited portion of the 
descending thoracic aorta (a relatively immobile structure) not susceptible to motion artifacts 118-121 . 
Current improvements in pulse sequence design have enabled motion-free high-resolution coverage of 
the entire aorta including the arch 122,123 . We have tested the ability of such an approach for 
wholebody plaque, carotid and lower extremity imaging 106,107,124 . Coverage of the entire aorta 
allows detection of smaller changes, allows inclusion of smaller numbers of patients and provides an 


improvement over invasive surrogate measures acquired in limited portions of the arterial bed (83-
86).125,126 4) Focus on monocyte miRNAs (versus plasma): While plasma miRNAs are under 
investigation as biomarkers, miRNA detection is limited by low amounts of RNA, lack of standardization, 
and lack of endogenous controls. In addition, since plasma miRNA expression is likely the result of 
several cell types, the biological and mechanistic relevance of changes are challenging. Peripheral blood 
mononuclear cells (PBMCs) provide unique advantages over plasma miRNAs in atherosclerosis (see 
below). Evidence of the importance of miRNAs in peripheral blood mononuclear cell (PBMC) is well 
established in diseases such as cancer and COPD 89,127- 130 . 5) miRNAs as Predictors of 
Response/Disease: Atherosclerosis is a complex disease and it is unlikely that expression of a single gene 
or marker may predict it. However understanding of candidate miRNAs and key factors such as MR 
through their role in regulating hundreds of genes and influencing phenotypes such as A are far more 
likely to be informative. The figure illustrates this concept where miRNAs and the transcription factor 
MR may potentially influence functional networks of genes and thereby affect A. Our investigations 
thus may shed light on the role of each of these “levels” of regulation in atherosclerosis. 
Risk / Benefit Assessment  
All potential patients will be informed of the potential side effect profile prior to enrollment in the study 
and full informed consent will be utilized. 
Risks of an MRI Scan  
There are no risks associated with the MRI scan. In our center approximately 10% of patients are 
genuinely claustrophobic. 
Reproductive Risks  
Spironolactone may cause risks to the unborn fetus and or the baby of a nursing mother. Therefore, 
pregnant women and women who are nursing their babies should not participate in the study. Woman 
must be either post-menopausal for one year, surgically sterile, or using effective contraception. A 
pregnancy test will be required at screening for all woman who may become pregnant. A negative test is 
required for the individual to enroll in the study. Participants who become pregnant will report to the 
study PI immediately, and stop taking the pills. 
Spironolactone can decrease the effectiveness of birth control pills. Women who use oral birth control 
methods will be excluded from the study. Women of child bearing potential should use another reliable 
form of contraception. Acceptable methods of birth control include subcutaneous implants, intrauterine 
devices (IUD), barrier methods, surgical sterility, transdermal birth control path, and abstinence. 
Side Effects Related to Study Drug 
Common Side Effects 
 
Hyperkalemia: We anticipate that approximately 1% of patients may develop serious 
hyperkalemia that may warrant discontinuation. However this may be considerably higher in 
patients with GFR of 40-50 ml/minute who will constitute a minority of the patients in the trial.  
 
Increases in BUN and creatinine  
 
Gynecomastia or breast discomfort. Gynecomastia is a well-described adverse effect of 
spironolactone and is related to dose and duration of treatment; we anticipate that 


approximately 10% of patients may develop gynecomastia that may warrant discontinuation. 
Generally, discontinuation of treatment results in resolution of gynecomastia.

Cardiovascular: Vasculitis  


Potential Benefits of the Proposed Research to the Subjects and Others  
It is possible that there may be a benefit with Spironolactone in terms of organ protection and patients 
may see benefits relating to reduction of atherosclerotic plaque including reduction in risk for events 
such as heart attacks, stroke, renal failure and need for hospitalization. The potential benefits must 
obviously be contrasted with the risk for renal failure and hyperkalemia. 
Importance of the Knowledge to be Gained  
There is an urgent need for clinical trials aimed at reducing the disproportionate cardiovascular disease 
burden and mortality in Type II diabetes. The multiple cardiovascular benefits of mineralocorticoid 
receptor (MR) blockade (using spironolactone or eplerenone) are well recognized in patients without 
Type II diabetes in the setting of congestive heart failure or myocardial infarction. However, randomized 
trials of MR Blockade have not been conducted in patients with atherosclerosis. A potential role for MR 
blockade for slowing atherosclerosis progression as well as influencing cardiovascular outcomes in 
diabetic patients is only beginning to attract the attention of cardiologists. Patients with atherosclerosis 
may benefit from MR blockade if, on one end of the spectrum, such intervention is made relatively early 
in the course of Type II diabetes to slow progression and of atherosclerosis and inflammation or 
plausibly at the other extreme when patients are already at very high risk patient population for 
cardiovascular events and mortality. The use of Spironolactone in patients with type II diabetes and 
atherosclerosis has not been well studied.

adverse events. They will be asked to bring their patient diary to each study visit along with all used and 
unused study drug containers. 
HYPERKALEMIA MANAGEMENT  
One of the most significant complications of the study medications is hyperkalemia. This risk is of 
particular importance in this study population as diabetic patients with chronic kidney disease are at 
increased risk for selective aldosterone deficiency, predisposing them to the development of 
hyperkalemia. Mild to moderate hyperkalemia is generally not associated with significant cardiac 
toxicity, especially when it is chronic (e.g., in dialysis patients) or slowly developing. In contrast, severe 
(> 6.5 mEq/L) or rapidly developing hyperkalemia is likely to be associated with the development of ECG 
abnormalities ranging from peaking of the T- wave; to atrial, AV nodal and ventricular conduction 
delays; and ultimately, with very severe hyperkalemia, to ventricular fibrillation.  
Dietary intake of potassium is a major factor in producing hyperkalemia and transient dietary increases 
in potassium intake can precipitate hyperkalemia in our patients. For example, a single high potassium 
meal prior to blood draw could result in high potassium at the time of the draw but later on a repeat the 
potassium may be much lower, as much as 1 mEq/L lower. 
Decreased cellular uptake of potassium occurs when insulin is relatively deficient. Even a patient who is 
not on insulin can have relative insulin deficiency (also known as insulin resistance). Generally decreased 
cellular uptake of potassium occurs when a patient has ingested a high potassium diet but does not have 
enough insulin to drive potassium into the cell. This can result in transient hyperkalemia.  


Factors that impair renal excretion of potassium and can contribute to hyperkalemia in addition to the 
study medication include: 1) decreased GFR; 2) drugs including NSAIDS (e.g. ibuprofen), COX-2 inhibitors 
(e.g. celecoxib) and 3) any process which decreases distal tubular flow rate such as can occur in the 
setting of volume depletion.  
One or all of the above factors can be operative in the same patient. For example, a volume depleted 
patient can have relative insulin deficiency, a high potassium intake and have taken NSAIDS for pain 
while ingesting the study medication.  
Subjects will be counseled to avoid medications that may increase the risk of hyperkalemia, such as non-
prescription non-steroidal anti- inflammatory medications, and potassium-containing salt substitutes. All 
subjects will be monitored for the development of hyperkalemia at each follow-up visit and an ECG will 
be obtained for any potassium value > 6.0 mEq/L.  
The aggressiveness of treatment of hyperkalemia will depend on the degree of elevation and the 
presence or absence of ECG findings. 
Treatment of hyperkalemia for Potassium > 5.0 meq/L: Dietary potassium  
If during follow-up, a subject's potassium level increases to > 5.0 mEq/L, he/she will be prescribed a low 
potassium diet (0.7-0.8 meq/kg/day to a maximum daily intake of 60 meq/day). An initial step would be 
to restrict potassium in the diet. Input from a dietician can be helpful.  
There is potassium in most foods, but certain foods are especially high in potassium and should be 
avoided. Some high potassium foods can be eaten after leaching the potassium by soaking. Many salt 
substitutes are potassium chloride and should be avoided. Fruits and vegetables should be limited to 
four servings per day. Dairy products should be limited to 1 cup/day. 
High Potassium Foods (avoid):  
Fruits and juice: apricots, avocado, banana, cantaloupe, honeydew, dried fruit (dates, raisins, prunes, 
figs), citrus fruits (orange, grapefruit, nectarines)  
Vegetables: artichoke, butter beans, dried peas or beans, potatoes (unless leached), sweet potatoes, 
Swiss chard, winter squash.  
Other: chocolate, molasses, nuts, peanuts 
Medium potassium foods: Limit to one serving (1/2 cup)/day:  
Fruits: blackberries, cherries, peach (1), pear (1), raspberries, strawberries, watermelon (1 cup), plums 
(2) 
Vegetables: broccoli (cooked), carrot, mushroom, peas, corn, cabbage, eggplant, spinach (cooked), 
pumpkin, tomato, potato (leached), beets 
Low potassium foods (note that portion size is 1/2 cup, eating a large amount of a lower potassium food 
will make it a higher potassium food)  
Fruits (including juice): Apple, blueberries, cranberries, grapes, tangerine (1 small) Vegetables: green 
beans, wax beans, cucumber, green pepper, lettuce, yellow squash  


Leaching vegetables: For potatoes, sweet potatoes, carrots, beets and rutabagas:  
Peel and slice vegetables 1/8 inch thick  
Rinse  
Soak for a minimum of two hours in warm water, using 10 times the amount of water to the amount of 
vegetables. If soaking longer, change the water every few hours  
Rinse under warm water  
Cook with five times the amount of water to the amount of vegetable 
Treatment of hyperkalemia for Potassium > 5.5 meq/L  
In addition to a low potassium diet, if the potassium level increases to >5.5 mEq/L, conservative 
measures should be instituted.  
Possible approaches include:  
Increase in diuretics if volume depletion is not a concern. Volume depletion could worsen hyperkalemia  
Administration of chronic alkali supplements, such as sodium bicarbonate 1300mg bid if acidosis is 
present  
Liberalization of salt intake (if volume status and uncontrolled blood pressure are not concerns)  
Chronic use of low-dose sodium polystyrene sulfonate (15-30 grams 3x/week) 
Treatment of hyperkalemia for Potassium > 6.0 meq/L  
If the potassium level is > 6.0 mEq/L, the study medication will be held until the level decreases to < 5.5 
mEq/L.  
Acutely to treat the potassium:  
An ECG should be checked. If there are no ECG changes and potassium level is < 6.5, then Kayexalate 
alone (60 grams) may be sufficient. If there are ECG changes, treatment would include insulin/glucose, 
beta-agonists and possibly calcium and bicarbonate. If there are ECG changes or if the potassium level is 
> 6.5 meq/L, the patient should be treated in the emergency room. If there are ECG changes, the patient 
should be placed on a cardiac monitor. 
Reinstitution of Study Medication  
If the potassium level was > 6.5, then the study medication will be permanently discontinued and the 
patient will be removed from the trial. If this is the second episode where potassium > 6.0, then the 
study medication will be permanently discontinued and the patient will be removed from the trial.  
Recheck potassium level 7- 14 days after discontinuation. If K+ is > 5.5 mEq/L, do not restart study 
medications. Repeat potassium again in 7-14 days. If K+ is ≤ 5.5 mEq/L, the study medication will be 
reinstituted at 50% of prior dose. 
 
If the study medication was restarted, check potassium level again in two weeks, if K+ is:  


o > 6.0: stop study the study medication permanently  
o 5.5-6.0: treat K+, maintain current dose of the study medication  
o < 5.5: mEq/L and patient is on at least 12.5 mg spironolactone, increase spironolactone to 
25mg daily. 
 
STUDY PROCEDURES AND GUIDELINES  
Prior to conducting any study-related activities, written informed consent and the Health Insurance 
Portability and Accountability Act (HIPAA) authorization must be signed and dated by the subject. If 
appropriate, assent must also be obtained prior to conducting any study-related activities. Study visits 
will be conducted on the scheduled day or within +/- 2 days for weekly study visits and +/- 7 days for 
monthly visits. 
Schedule of Events 
Vanguard Phase ( update to reflect table below) 
 


 
Main Study Phase 
 
Clinical Assessments  
A complete medical history and physical exam will be performed at baseline and will include a 12-lead 
electrocardiogram (EKG), cardiovascular risk factor assessment, intercurrent CV events, 7-day physical 
activity recall, active/passive smoking questionnaires and dietary recall questionnaire. Sitting systolic 
blood pressure, pulse rate, body weight, interim event logs, pill counts, medication logs will be recorded 
at most clinic visits. Central aortic blood pressure will be obtained during visit 2 (base), 6 (midpoint) and 
8 (exit) while 24-hour BP will be measured at Visit 2 and 6. Dietary Na+ consumption: Since Na intake is 
an important determinant of MR responsiveness we will ensure that all patients receive dietary 
survey/instructions (Visit 0) on maintaining a personalized diabetic diet that is stable and is medium to 
low in sodium (<4g). We will obtain Na, K and Creatinine levels (Visit 2) to assess Na intake. The 
kawasaki formula will be used to estimate 24 hour urine.

Coronavirus Outbreak (COVID-19) Management Plan under Public Health Mandates  
The following guidelines were developed under polices set forth by UH Cleveland Medical Center, the 
University of Maryland, NYU Winthrop, and St. Michael’s Hospital in Toronto. All participating sites will 
be taking the following preventative measures to reduce the spread of the COVID-19 virus to research 
patients and staff.  
 


Recruitment and Enrollment  
Under the new implemented COVID-19 policies, we will not enroll new participants in the United States 
and Canada. No new participants will be enrolled until deemed safe by the affiliated research 
institutions. Study procedures will revert to the original procedures described in Section 11 “Procedures 
and Guidelines” once the mandates are lifted. During this time, pre-screening may continue according to 
the discretion of each study site. Potentially eligible subjects will be placed on a waiting list to be 
screened and enrolled once mandates are lifted. 
Active Participants and Follow up Visits  
At the time COVID-19 policies were implemented, active participants fell into either the “run in phase” 
or the “treatment phase” of the study procedures timeline of events (See 11.1.2 Main Study Phase).  
RUN-IN-PHASE Patients in the run-in-phase (visit 1) will postpone visit 2 until safe medication 
compliance and follow up labs can be performed.  
TREATMENT-PHASE In order to simultaneously reduce transmission of the virus while maintaining the 
management of participant’s follow up care to the best extent possible, pertinent study activities (i.e. 
safety labs & vital signs) will be attempted in conjunction with any provider scheduled clinical encounter 
deemed essential for clinical care. If this is not possible, patients will be given an additional prescription 
until the essential study activities can be performed safely (length of prescription may vary based on 
patients’ recent bloodwork and BP/HR, specific site policies, and investigator’s medical judgment). 
Additional important details  
Remote study visits are not appropriate for this study.  
Participants will be compensated for their participation at the same amount specified in the original 
consent through site-specific means.  
All enrolled participants at each site will be notified by phone call of these protocol changes enacted 
during the period of public health mandates. 
ADVERSE EXPERIENCE REPORTING AND DOCUMENTATION  
Adverse Events  
An adverse event (AE) is any untoward medical occurrence in a clinical investigation of a patient 
administered a pharmaceutical product and that does not necessarily have a causal relationship with the 
treatment. An AE is therefore any unfavorable and unintended sign (including an abnormal laboratory 
finding), symptom or disease temporally associated with the administration of an investigational 
product, whether or not related to that investigational product. An unexpected AE is one of a type not 
identified in nature, severity, or frequency in the current Investigator’s Brochure or of greater severity or 
frequency than expected based on the information in the Investigator’s Brochure. The Investigator will 
probe, via discussion with the subject, for the occurrence of AEs during each subject visit and record the 
information in the site’s source documents. Adverse events will be recorded in the patient CRF. 
AE Severity  


The National Cancer Institute’s Common Terminology Criteria for Adverse Events (CTCAE) in Table 1 
should be used to assess and grade AE severity, including laboratory abnormalities judged to be clinically 
significant. If the experience is not covered in the CTCAE, the guidelines shown in Table 2 below should 
be used to grade severity. It should be pointed out that the term “severe” is a measure of intensity and 
that a severe AE is not necessarily serious. K+ >6.0 will be considered an adverse event. K+5.0 will be 
treated according to the hyperkalemia protocol. 
National Cancer Institute’s Common Terminology Criteria for Adverse Events 
 
AE Severity Grading 
 
 


AE Relationship to Study Drug  
The relationship of an AE to the study drug should be assessed using the following the guidelines in 
Table 3. 
Table 3. AE Relationship to Study Drug 
 
Serious Adverse Experiences (SAE)  
An SAE is defined as any AE occurring at any dose that results in any of the following outcomes:  
 death  
 a life-threatening adverse experience  
 inpatient hospitalization or prolongation of existing hospitalization  
 a persistent or significant disability/incapacity  
 a congenital anomaly/birth defect Other important medical events may also be considered an 
SAE when, based on appropriate medical judgment, they jeopardize the subject or require intervention 
to prevent one of the outcomes listed. 
 
 


Serious Adverse Experience Reporting  
Adverse events will be documented per the University Hospitals Cleveland Medical Center, Human 
Research Protections guidelines, reported to the IRB, DSMB and the sponsor. The collection period for 
all SAEs will begin after informed consent is obtained and end after procedures for the final study visit 
have been completed. 
Medical Monitoring  
Dr. Matthew Weir and/or Dr. Jeffrey Fink should be contacted directly to report medical concerns or 
questions regarding safety. 
DISCONTINUATION OF SUBJECTS 
Early Discontinuation of Study Drug  
A subject may be discontinued from study treatment at any time if the subject, the investigator, or the 
Sponsor feels that it is not in the subject’s best interest to continue. The following is a list of possible 
reasons for study treatment discontinuation:  
Subject withdrawal of consent (or assent)  
Subject is not compliant with study procedures  
Adverse event that in the opinion of the investigator would be in the best interest of the subject to 
discontinue study treatment  
Protocol violation requiring discontinuation of study treatment  
Lost to follow-up  
Sponsor request for early termination of study  
Positive pregnancy test (females)  
If a subject is withdrawn from treatment due to an adverse event, the subject will be followed and 
treated by the Investigator until the abnormal parameter or symptom has resolved or stabilized. 
All subjects who discontinue study treatment should come in for an early discontinuation visit as soon as 
possible and then should be encouraged to complete all remaining scheduled visits and procedures. 
All subjects are free to withdraw from participation at any time, for any reason, specified or unspecified, 
and without prejudice.  
Reasonable attempts will be made by the investigator to provide a reason for subject withdrawals. The 
reason for the subject’s withdrawal from the study will be specified in the subject’s source documents. 
DATA SAFETY MONITORING  
A Data Safety Monitoring Board (DSMB) will be established to review data relating to safety and efficacy, 
to conduct and review interim analyses, and to ensure the continued scientific validity and merit of the 
study. Reviews will be conducted by the DSMB every 3 months for the purpose of monitoring study 
conduct and assessing patient safety. 


STATISTICAL METHODS AND CONSIDERATIONS  
Prior to the analysis of the final study data, a detailed Statistical Analysis Plan (SAP) will be written 
describing all analyses that will be performed. The SAP will contain any modifications to the analysis 
plan described below. General Statistical Considerations: All the tests are two-sided. We use log 
transformations for most continuous measures, and arc-sin square root transformations for 
percentages, both of which have excellent variance stabilizing properties for pooling variance. 
Aim 1: To test change in percent total atheroma volume (PAV) in thoracic aorta with Spironolactone 
vs. placebo  
N=52 per group is required in order to have 80% power to detect at least 1.5 fold difference in change in 
PAV between the two group (α=0.05; CV=83%). Assuming a 20% loss to follow up rate by 54 weeks, we 
need to recruit 130 patients. TABLE 7 lists the power calculations for the primary end-point in Aim 1. 
 
TABLE 8 provides the power for mean differences on reproducibility of central aortic BP and PWV from 
our own data. 
 
 


Analysis Plan: After distributions are checked and outliers are investigated for veracity, descriptive 
statistics by treatment arm will be reported for patient demographics and important potential 
confounding variables at baseline. These will include age, gender, BMI, baseline blood pressure, HbA1c, 
24-hour urine Na, plasma and renin/aldo activity at baseline, HOMA-IR, HDL and non-HDL cholesterol. 
To analyze these data (primary end points and secondary outcome measures), linear mixed models with 
group (drug/placebo), baseline plaque volume, time points (before/after), stratification variables (age, 
high-risk feature) and other potential confounders (such as demographics and other comorbidities) as 
well as a patient random effects (to account for the correlation of measures within same patient) will be 
used. Different covariance structures will be used and best model will be selected based on AIC criteria 
by first fitting most complicated mean structure model, selecting the best covariance structure, then 
selecting the best mean structure, using SAS procedure GLIMMIX or MIXED) and convergence and model 
performance will be evaluated using SAS fit statistics (e.g. AIC criteria). Clinically relevant interactions 
will also be included in the models. Forward stepwise selection followed by backward elimination will be 
used to retain features with the greatest combined prediction power while maintaining parsimony using 
a training data set. Traditional methods, such as AIC and BIC involve a combinatorial optimization 
problem, which is NP-hard, with computational time increasing exponentially with the dimensionality. 
The expensive computational cost makes traditional procedures infeasible for high-dimensional data 
analysis. To overcome this, penalized likelihood maximization and penalized risk minimization have been 
intensively used for classification. Penalized methods with Lp-penalty, especially when p≤1, 
automatically perform variable selection by removing predictors with very small estimated coefficients. 
Fan et al. proposed SCAD-penalty with better oracle properties 131 . It automatically selects features 
and avoids excessive estimation bias compared to L1- penalty. We will use penalized methods for 
classification in order to avoid over-fitting problems by producing sparse solutions via feature selection. 
Aim 2a: To evaluate the functional significance of candidate miRNAs.  
Analysis Plan: An interaction contrast in an ANOVA model will be used to test the effects of 
overexpression of miRNAs (miR mimic) or antagomiRs in various experiments where we will test the 
effect of miRNAs alone or in the presence of LPS or IL4/13. The effect of various interventions on NR3C2 
gene expression and MR protein expression as well as markers of alternate activation will be tested. 
Aim 2b: To compare monocyte polarization and inflammatory gene expression at 6-weeks  
Analysis Plan: Comparison of expression of these markers between groups will be done with ANOVA. 
Alterations in the percent change in monocyte subsets will be correlated with both the primary end-
point ( PAV) and secondary end-points including change in HOMA-IR, SBP (central aortic) and PWV. 
Aim 2c: To evaluate miRs expression to predict atherosclerosis and response  
In an exploratory analysis, similar model selection strategy as in aim 1 will be applied which will include 
traditional risk factors. Based on the model we generated in aim 1, we will add miRNAs as additional 
factors (singly and in combination). Using this model, we will be able to test the effect of miRNA(s) at 
baseline on the rate of atherosclerosis progression and to identify patients who demonstrate greater 
response (e.g. decreases in PAV). The first half of patients (n=30 per group) will be used to build our 
model (training stage). The rest of the patients enrolled will be used to validate this model (validation 
stage). Features that are dropped from the model because of redundancies will be retained for further 
univariate testing in the validation data. Combining biological and clinical deliberations with statistical 


results will likely generate a few alternative models with similar prediction accuracy. Cross-validation 
will be used to evaluate a classifier’s prediction accuracy and for choosing the best tuning parameters. 
The classifier’s prediction accuracy will be the main objective of this aim. For sample size calculations, 
we use the method described by Dobbin et al. 183, 184, which is based on the assumption that the 
expected accuracy of the classifier is controlled within a percentage (tolerance) of the best possible 
classifier. Assuming a maximum tolerance of 5% (and at most a 2-fold difference in the differentially 
expressed miRNAs (assuming a median SD of 0.71), a sample size of n=60 total (training and validation 
sets) is required. Tolerance represents the difference in the probability of correct classification in the 
training sample with respect to the same probability from an optimal signature. This sample size does 
not guarantee that there will be differentially expressed miRNAs. Instead, this sample size will be 
enough to validate a differentially expressed miRNAs, if such miRNAs is found in the data. Baseline 
miRNAs will also be correlated with markers of alternate activation (CD206+ and CD163+ monocytes) 
and MR gene/protein expression. 
DATA COLLECTION, RETENTION AND MONITORING 
Data Collection Instruments  
The Investigator will prepare and maintain adequate and accurate source documents designed to record 
all observations and other pertinent data for each subject treated with the study drug. Study personnel 
at each site will enter data from source documents corresponding to a subject’s visit into the protocol-
specific electronic Case Report Form (eCRF) OR paper CRF when the information corresponding to that 
visit is available. Subjects will not be identified by name in the study database or on any study 
documents but will be identified by a subject number. 
Data Management Procedures  
The data will be entered into a validated database. The Data Management group will be responsible for 
data processing, in accordance with procedural documentation. Database lock will occur once quality 
assurance procedures have been completed. All procedures for the handling and analysis of data will be 
conducted using good computing practices meeting FDA guidelines for the handling and analysis of data 
for clinical trials. 
Archival of Data  
The database is safeguarded against unauthorized access by established security procedures; 
appropriate backup copies of the database and related software files will be maintained. Databases are 
backed up by the database administrator in conjunction with any updates or changes to the database. 
At critical junctures of the protocol (e.g., production of interim reports and final reports), data for 
analysis is locked and cleaned per established procedures. 
Availability and Retention of Investigational Records  
The Investigator must make study data accessible to the monitor, other authorized representatives of 
the Sponsor (or designee), IRB/IEC, and Regulatory Agency (e.g., FDA) inspectors upon request. A file for 
each subject must be maintained that includes the signed Informed Consent, HIPAA Authorization and 
copies of all source documentation related to that subject. The Investigator must ensure the reliability 
and availability of source documents from which the information on the CRF was derived. 


Subject Confidentiality  
In order to maintain subject confidentiality, only a subject number will identify all study subjects on CRFs 
and other documentation submitted to the Sponsor. 
ADMINISTRATIVE, ETHICAL, REGULATORY CONSIDERATIONS  
The study will be conducted according to the Declaration of Helsinki, Protection of Human Volunteers 
(21 CFR 50), Institutional Review Boards (21 CFR 56), and Obligations of Clinical Investigators (21 CFR 
312). To maintain confidentiality, all laboratory specimens, evaluation forms, reports and other records 
will be identified by a coded number only. All study records will be kept in a locked file cabinet and code 
sheets linking a patient’s name to a patient identification number will be stored separately in another 
locked file cabinet. Clinical information will not be released without written permission of the subject, 
except as necessary for monitoring by the FDA. The Investigator must also comply with all applicable 
privacy regulations (e.g., Health Insurance Portability and Accountability Act of 1996, EU Data Protection 
Directive 95/46/EC). 
Informed Consent Form  
Informed consent will be obtained in accordance with the Declaration of Helsinki, ICH GCP, US Code of 
Federal Regulations for Protection of Human Subjects (21 CFR 50.25[a,b], CFR 50.27, and CFR Part 56, 
Subpart A), the Health Insurance Portability and Accountability Act (HIPAA, if applicable), and local 
regulations. A properly executed, written, informed consent will be obtained from each subject prior to 
entering the subject into the trial. Subjects will be given ample opportunity to inquire about details of 
the study. If a subject is unable to sign the informed consent form and the HIPAA authorization, a legal 
representative may sign for the subject. A copy of the signed consent form will be given to the subject or 
legal representative of the subject and the original will be maintained with the subject’s records. 
Publications  
The preparation and submittal for publication of manuscripts containing the study results shall be in 
accordance with a process determined by mutual written agreement with the study Sponsor. The 
publication or presentation of any study results shall comply with all applicable privacy laws, including, 
but not limited to, the Health Insurance Portability and Accountability Act of 1996.
