If Yes, complete a-h. If no, skip to Item 11 
a. How will specimens be obtained, processed, distributed, and stored?  
Blood and urine from 3 study visits will be labeled and stored in a Fisherbrand cryo/freezer 
box in a temperature controlled and monitored freezer located in the Ziegler Research 
Building (Rm 510) 
 
b.  How will specimens be labeled (e.g., unique identifier, medical record number, 
Social Security number, name, date of birth)?  
Specimens will be labeled by study name, participant study number, and date of collection. 
 
c.  How will clinical data associated with the specimens be collected and stored?  
Clinical data associated with the specimens will be kept in the study database.  The database 
will be maintained on a computer with access restricted by password protection to study staff.  
A non-specific participant number will be generated for each participant.  The list linking the 
participant numbers to the participant identifiers will kept in a secure location with password-
protection and only the PI and designated study personnel will have access to this list.  Data 
will be stored with use of the participant numbers without identifiable labels such as names, 
medical record number or social security number. 
 
d.  What participant-identifying information will be collected and linked to the 
specimens?  
Participant name and date of birth will be recorded in the list linking participant number to 
the participant identifiers. 
 
e.  What steps will be taken to maximize the confidentiality of linked identifiers? 
For example, procedures could include using a password-protected computer 
database to link identifiers, with limited personnel knowledgeable of the 
password, or coded identifiers released without the ability to link to clinical data 
(also called "stripped" or "anonymized" specimens).  
As described in part c, data collected throughout the study will be stored in a database 
maintained on a computer with access restricted by password protection to study staff.  The 
specimens will be labeled with de-identified codes (participant number and date of collection). 
 
f.  Will specimens be shared with other investigators in the future?  
Yes 
No  
If Yes, what identifiers, clinical information and demographic information will 
be shared; or will the specimens be stripped of identifiers (i.e., anonymized)? 
Also if yes, outline your procedure for assuring IRB approval for release and 
use prior to release of specimens.  
 
 Specimens that are provided to other investigators will remain stripped of identifiers.  
Participant demographics including age, gender, race, and comorbidities will also be provided 
in a de-identified form using participant study number (e.g., CKD1501).  
 

HSP  
Vascular Spiro CKD Revised 3 21 2017

 Note. Investigators who receive and/or use these specimens must document 
approval from the appropriate IRB(s) before the specimens may be released. 
 
g.  Will biological samples be stored for future use? 
Yes 
No 
If Yes, indicate whether they will be used for the disease under study in this 
protocol or research on other diseases.  
Blood and urine samples will be stored with the potential for future testing for the disease 
under this study protocol (e.g., vascular function in chronic kidney disease).  
 
h. Is genetic testing planned?  
Yes 
No 
If Yes, describe the planned testing here and see "DNA/Genetic Testing" in the 
Guidebook for consent requirements.

Few therapies exist to prevent or slow the progression of chronic kidney disease, a disease with a 
large public health burden.  This project investigates the vasculature as a novel target for chronic 
kidney disease treatment. 
 
14. Background—in nontechnical, lay language 
Summarize in 2-3 paragraphs past experimental and/or clinical findings leading to the 
formulation of this study. Include any relevant past or current research by the 
Principal Investigator. For drug and device studies summarize the previous results 
(i.e., Phase I/II or III studies). 
Chronic kidney disease, an inpairment in kidney function beyond age-expected decline, is 
commonly attributed to kidney damage from diabetes mellitus and/or hypertension.  While the 
direct mechanism(s) of kidney injury resulting from these comorbidities has yet to be defined, it 
has been hypothesized that the vasculature is involved in kidney function.  This hypothesis is 
supported by the evidence that the one proven therapy for chronic kidney disease, namely 
angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), 
improves vascular function.   
 
In our study of patients with resistant hypertension, we have shown that vascular function 
improves with the use of spironolactone, a mineralocorticoid receptor antagonist.  Spironolactone 
has also been shown to reduce urinary protein loss in patients with chronic kidney disease.  
Therefore, it is reasonable to suppose that spironolactone can improve vascular function in 
patients with chronic kidney disease.  Currently spironolactone is used sparingly in early stages of 
chronic kidney disease and is avoided in late stages of chronic kidney disease due to the risk of 
raising serum potassium levels.  If spironolactone improves vascular function in patients with 
moderate stages of chronic kidney disease, as it has been shown to do in patients with resistant 
hypertension, then defining this mechanism would open new therapeutic avenues for patients with 
chronic kidney disease.

Age: 19-65 years of age 
Health status: Participants with a moderate stage of chronic kidney disease 
 
Note. If data from prior studies indicate differences between the genders or among 
racial/ethnic groups in the proposed research or if there are no data to support or to 
negate such differences, Phase 3 clinical trials will be required to include sufficient 
and appropriate entry of gender and racial/ethnic subgroups so that trends detected 
in the affected subgroups can be analyzed. If ethnic, racial, and gender estimates are 
not included in the protocol, a clear rationale must be provided for exclusion of this 
information. If prior evidence indicates that the results will not show gender or racial 
differences, researchers are not required to use gender or race/ethnicity as selection 
criteria for study participants. They are, however, encouraged to include these 
groups. See Section II. Policy of the NIH POLICY AND GUIDELINES ON THE 
INCLUSION OF WOMEN AND MINORITIES AS SUBJECTS IN CLINICAL RESEARCH – 
Amended, October, 2001) for further details.  
 
c. From what population(s) will the participants be derived?  
Participants will be primarily recruited from a database of former and active patients of the UAB 
Hypertension Clinic totaling over 1400 patients, over 200 of which have eGFRs < 60 
mL/min/1.73m2.  Additional recruitment will come from a database of patients seen in the CKD 
clinic at the Kirklin clinic and the PI’s renal clinics both at the Kirklin Clinic and at Cooper 
Green.     
 
Describe your ability to obtain access to the proposed population that will allow 
recruitment of the necessary number of participants: 
The PI has maintained a database of hypertension patients while working in Dr. David Calhoun’s 
Hypertension Clinic at the Kirklin Clinic.  A letter signed by Dr. David Calhoun and Dr. Eric 
Judd will be mailed to potential participants identified in this database.  The PI will recruit 
directly from his clinics at the Kirklin Clinic and at Cooper Green, where he is an attending in the 
renal clinic.  A letter signed by Dr. Eric Judd and Dana Rizk, the director of the CKD clinic at the 
Kirklin Clinic, will be mailed to potential participants identified in the CKD database.  
 
 
Describe the inclusion/exclusion criteria: 
Table 1. Study inclusion and exclusion criteria 
Inclusion 
Criteria 
 Adults (19-65 years of age) 
 CKD (eGFR 25-60 mL/min/1.73m2) with urine ACR > 30 mg/gCKD (eGFR > 60 
mL/min/1.73m2) with urine ACR ≥ 300 mg/g 
Exclusion 
Criteria 
 Severe HTN (office BP ≥ 160/100 mm Hg) 
 Hypotension (office BP < 110/70 mm Hg) 
 Serum potassium > 5 mEq/L 
 History of arrhythmia, including atrial fibrillation 
 Pregnant or breast feeding woman 
 DM type 1  
 DM type 2 with hemoglobin A1C ≥ 6.5 % 
 Dementia or cognitive impairment prohibiting informed consent 
 History of ischemic stroke, unstable angina, or myocardial infarction within the 
past 6 months 
 Allergy or intolerance to spironolactone or amiloride 
 Use of an MR antagonist or an epithelial sodium channel blocking medication 
within the last month 

HSP  
Vascular Spiro CKD Revised 3 21 2017  
Page 14 of 21 
 Known primary aldosteronism or renal artery stenosis 
ACR = albumin-to-creatinine ratio, HTN = hypertension, BP = blood pressure, DM = diabetes 
mellitus, MR = mineralocorticoid receptor 
Patients with severe hypertension (office BP > 160/100 mm Hg) are excluded due to 1) the 
possibility of requiring blood pressure medication changes during the study period, 2) direct 
effects of blood pressure on vascular function testing, and 3) increased cardiovascular risk leading 
to potential serious adverse events.  Patients with hypotension (office BP < 110/70 mm Hg) were 
excluded due to an expected drop in blood pressure with administration of spironolactone and/or 
amiloride. 
 
d. If participants will comprise more than one group or stratification, describe each 
group (e.g., treatment/intervention, placebo, controls, sham treatment) and 
provide the number of participants anticipated in each group. 
 
This clinical trial follows a cross-over design.  All participants are scheduled to receive both study 
medications in series with randomization to the initiating therapy (See Figure 2). 
 
e. Indicate which, if any, of the special populations listed below will be involved in 
the protocol. Include the Special Populations Review Form (SPRF) if indicated.

g. Describe the process  (e.g., recruitment, chart review) that will be used to seek 
potential participants (e.g., individuals, records, specimens). Research recruitment 
by non-treating physicians/staff may require completion of Partial Waiver of 

HSP  
Vascular Spiro CKD Revised 3 21 2017  
Page 15 of 21 
Authorization for Recruitment/Screening. (See 
http://main.uab.edu/show.asp?durki=61981.) 
For patients identified as potential participants through the hypertension and CKD 
databases, study personnel will review the medical history including the medical record in order 
to identify exclusion criteria.  Eligible participants who meet inclusion and exclusion criteria after 
this screening process will be mailed a letter co-signed by Drs. Judd and Calhoun for the HTN 
database and Drs. Judd and Rizk (Dr. Dana Rizk is the Director of the CKD clinic at the Kirklin 
Clinic) for the CKD database.  Potential participants will be contacted by phone to set up a 
screening visit where an investigator will review the risks and benefits of participation in a formal 
consenting process.   
 
Patients recruited from the PI’s Kirklin Clinic or Cooper Green clinic will have the study 
and its associated risks and benefits introduced by the PI during a regularly scheduled follow-up 
visit.  Patients interested in participating will have a screening visit scheduled where informed 
consent will occur. 
 
Patients who are scheduled to see a nephrologist at the Kirklin clinic will be prescreened 
using chart review in Impact to assess eligibility.  With approval from the patient’s nephrologist, 
patients who are eligible will be contacted either by phone or in person at their clinic visit.  If 
interested, potential participants will be scheduled for a screening visit where the informed 
consent process takes place.  As part of the consenting process participants are presented with a 
copy of the informed consent and are allowed an unlimited amount of time before deciding to 
proceed with the study.   
 
In order to meet recruitment goals, the electronic health record system for University of 
Alabama Hospital and Kirklin Clinic will be screened using i2b2 in order to generate a list of 
potential study candidates.  Once this list has been truncated further by chart review, the primary 
care doctor and/or primary nephrologist at UAB will be contacted to approve sending the patient 
a letter in the mail.  The recruitment letter is attached. 
 
h. If you will use recruitment materials (e.g., advertisements, flyers, letters) to reach 
potential participants, attach a copy of each item. If not, identify the source (e.g., 
databases) from which you will recruit participants.  Eligible participants identified in 
the hypertension and CKD databases will receive a letter alerting them to future contact by study 
personnel.   Other participants will be recruited directly from the PI (Dr. Eric Judd’s) Kirklin 
Clinic and Cooper Green clinic.  Flyers will be posted in designated areas at Cooper Green, UAB 
campus, and the Kirklin Clinic.    
 
i. Describe the procedures for screening potential participants.  
The medical history will be reviewed with the potential participant in a standard of care clinic 
visit.  If the patient agrees to participate, an investigator will review the consent form in person 
with the volunteer during a screening visit.  For potential participants identified in the databases, 
their medical records will be obtained through Horizon or Impact in order to identify exclusion 
criteria.  Review of medical records will be limited to study personnel (either the PI, sub-
investigator, or study coordinator).   
 
16. Protocol Procedures, Methods, and Duration of the Study—in nontechnical 
language 
a.  Describe the study methodology that will affect the participants—particularly in 
regard to any inconvenience, danger, or discomfort. 
Study participants with proteinuric, CKD will be randomly assigned in a double-masked fashion 
to spironolactone 25mg daily or amiloride 5 mg daily for 6 weeks and then crossed over to the 
alternate study medication after a 1 month wash-out period (See Figure 1).  Vascular function will be 
assessed at baseline and the end of each 6 week treatment period by: 1) ultrasound guided flow-
mediated dilation (FMD) of the brachial artery, 2) impedence cardiography, 3) pulse-wave velocity, 4) 

HSP  
Vascular Spiro CKD Revised 3 21 2017  
Page 16 of 21 
24 hour ambulatory blood pressure monitoring, and 5) serum and urine biomarkers.  Participants 
will undergo a total of 7 visits over 16-18 weeks; 3 of the 7 visits will involve vascular function testing.  
Pulse-wave velocity is measured non-invasively with placement of a small sensor (tonometry 
probe) over the carotid and femoral artery.  This procedure poses no discomfort and is usually done 
in about 15 minutes.  Impedence cardiography is also noninvasive with minimal inconvenience to the 
participant.  It is performed by placing small electrode pads on the chest wall and neck and takes 
about 12 minutes.  FMD is measured by assessing the change in brachial artery diameter by 
ultrasound.  A blood pressure cuff is placed below the elbow and inflated above systolic blood 
pressure for 5 minutes.  The cuff is then released and change in brachial artery is determined 
immediately afterwards for 2 minutes.  The entire procedure takes about 45 minutes.  Some back 
discomfort can occur with FMD testing as participants must lie flat for 30 minutes.  Hand and arm 
discomfort from cuff inflation is common yet resolves immediately after cuff deflation.  Collection of 
urine for 24 hours and wearing a blood pressure monitor for 24 hours can be disruptive to normal 
daily/nightly activities; however poses no danger or long-term inconvenience. 
A study visit where vascular function testing is to be performed will begin at 0800 in the morning 
and start with a vital sign assessment including height, weight, body fat percent, and left arm 
automated BP measurement followed by confirmation of fasting status and a brief past medical 
history.  Each participant will then lie supine for 10 minutes in preparation for vascular function 
testing.  Following the pulse wave velocity, impedence cardiography, and FMD measurements, the 
participant will have his/her blood and urine collected for laboratory testing.  Laboratory testing will 
include ~20 mL of blood for plasma and serum testing.  Participants will return 24 hour urine 
samples and have a 24 hour ambulatory monitor placed.  This entire visit is expected to take 2 hours.   
Study visits where vascular function testing will not be performed (e.g., screening visit, visit 2, visit 
4, and visit 5; see Table 2) should last 30 minutes and involve a medication assessment, vital sign 
check, and blood collection for serum potassium (~4 mL). 
All study medication will be prepared by the UAB Research Pharmacy in matching capsules.  .  
The order of medication dispensing will follow simple randomization using an a priori randomization 
list prepared by the research pharmacy.

17. Describe the potential benefits of the research.  
There is no anticipated direct benefit which the participants will obtain from participating in the 
protocol.  However, indirect benefits may include discovering that spironolactone or amiloride 
reduces albuminuria and/or blood pressure.  In addition, participants who experience an 
improvement in endothelial function with spironolactone use would be expected to have a lower 
cardiovascular risk with continued use.  We feel the risks involved with participating in this study 
are reasonable in relation to the potential benefits. 
 
18. Risks  
a. List the known risks—physical, psychological, social, economic, and/or legal—that 
participants may encounter as a result of procedures required in this protocol. Do 
not list risks resulting from standard-of-care procedures. Note. Risks included in 
this protocol document should be included in the written consent document.  
No undue hazards (physical, psychological, financial, legal, or other) are anticipated with vascular 
function testing or blood and urine sampling. Participants may be exposed to several potential 
risks as itemized below: 
1. Hyperkalemia: Administration of both spironolactone and amiloride are associated with 
increases in serum potassium of approximately 0.4 mEq/L.  Serum levels of potassium will 
be monitored at each study visit.  Kayexalate and a low potassium diet will be administered 
for levels of serum potassium > 5.5 meq/L followed by a repeat potassium level in 3 days.  
Participants will be withdrawn from the study with serum potassium levels > 6.0 meq/L.  In 
addition, participants will not be allowed to participate in the second treatment period with 
a serum potassium > 5.0 meq/L when checked at week 10.   
2. Fetal toxicity: Spironolactone is associated with fetal toxicity.  Pregnant women, as 
determined by a screening urine sample, are excluded from study participation.  Women of 
child bearing potential will be advised of the risk of fetal toxicity, and if a pregnancy occurs 
during the study the participant will be withdrawn and study medication stopped. 
3. Gynecomastia: Spironolactone is associated with breast growth in men.  This association 
occurs more frequently with the long-term use of doses exceeding 50mg/day. 
4. Discomfort and risks (hematoma/skin infection) associated venous blood collection 
5. Measurement of pulse wave velocity and performing impedence cardiography is non-
invasive and entails no risk. However, measurement of FMD requires that the subject be 
supine for 30 minutes, and inflation of the blood pressure cuff for 5 minutes may cause 
discomfort.  
 
b. Estimate the frequency, severity, and reversibility of each risk listed. 
1. Hyperkalemia, defined as a serum potassium concentration > 5.5 mEq/L, is expected to 
occur in less than 5% of study participants.  Serum potassium levels will be monitored 
within 2 weeks of starting either spironolactone or amiloride in order to prevent severe or 
prolonged hyperkalemia. Rises in serum potassium levels discovered in the first 2 weeks of 
the intervention are expected to resolve within 1-2 days of stopping the medication. 
2. Fetal toxicity is not expected to occur during the study.  Pregnant women, as determined by 
a screening urine sample, are excluded from study participation.  If a pregnancy occurs 
during the study, the participant will be withdrawn and study medication stopped. 
3. Discomfort and bruising is expected to occur in the majority of venous blood collections.  
However these complications of blood collection are mild.  A skin infection due to blood 
collection is not expected to occur as standard collection techniques involving sterile 
materials and alcohol preparation will be employed. 

HSP  
Vascular Spiro CKD Revised 3 21 2017  
Page 19 of 21 
4. Back discomfort from lying supine for 30 minutes for FMD measurement is expected to 
occur in less than 25% of study participants.  Lumbar support pillows are available if 
needed.  Hand and arm discomfort from blood pressure cuff inflation for 5 minutes 
commonly occurs with FMD measurement, yet completely resolves with cuff deflation.  
 
c. Is this a therapeutic study or intervention?  
Yes 
No 
 
If Yes, complete the following items: 
i. Describe the standard of care in the setting where the research will be 
conducted: The standard of care for non-diabetic patients with moderate (stage III) CKD is 
control of blood pressure and avoidance of nephrotoxic agents (e.g., nonsteroidal anti-
inflammatory and illicit drugs).  Patients with severely, uncontrolled blood pressure (e.g., 
>160/100 mm Hg) will be excluded from participation.  
 
ii. Describe any other alternative treatments or interventions: An angiotensin 
converting enzyme inhibitor (ACEI) or an angiotensin receptor blocker (ARB) is 
recommended for patients who have CKD and moderate levels of albuminuria and/or 
uncontrolled hypertension.  Participation in this clinical trial will not interfere with this 
therapy.  
 
iii. Describe any withholding of, delay in, or washout period for standard of care or 
alternative treatment that participants may be currently using: Patients taking 
spironolactone, amiloride, or triamterene at baseline will be offered to hold this medication for 
1 month prior to starting the study.  All participants will undergo a 1 month washout between 
the 2 intervention periods. 
 
 
d. Do you foresee that participants might need additional medical or psychological 
resources as a result of the research procedures/interventions?  
Yes 
No 
If Yes, describe the provisions that have been made to make these resources 
available.   
      
 
e. Do the benefits or knowledge to be gained outweigh the risks to participants?  
 
 
Yes 
No 
If No, provide justification for performing the research:      
 
19. Precautions/Minimization of Risks (If study involves drugs or devices 
complete the Drug or Device Review Sheet and skip to question #20) 
a. Describe precautions that will be taken to avoid risks and the means for monitoring 
to detect risks.  
 
 
b. If hazards to an individual participant occur, describe (i) the criteria that will be 
used to decide whether that participant should be removed from the study; (ii) the 
procedure for removing such participants when necessary to protect their rights 
and welfare; and (iii) any special procedures, precautions, or follow-up that will be 
used to ensure the safety of other currently enrolled participants.  
 
c. If hazards occur that might make the risks of participation outweigh the benefits 
for all participants, describe (i) the criteria that will be used to stop or end the 
entire study and (ii) any special procedures, precautions, or follow-up that will be 
used to ensure the safety of currently enrolled participants.

All discussions with potential participants will be done in clinic rooms with the door closed so 
others will not be able to overhear the conversation.  Potential participants will in no way be 
publicly identified or embarrassed. 
 
 
22. Procedures to Maintain Confidentiality 
a. Describe the manner and method for storing research data and maintaining 
confidentiality. If data will be stored electronically anywhere other than a server 
maintained centrally by UAB, identify the departmental and all computer systems 
used to store protocol-related data, and describe how access to that data will be 
limited to those with a need to know. 
The study database will be maintained on a computer with access restricted by password 
protection to study staff.  A non-specific participant number will be generated for each participant 
(e.g., CKD1501).  The list linking the participant numbers to the participant identifiers will kept in 
a secure location with password-protection, and only the PI and designated study personnel will 
have access to this list.  Data will be stored with use of the participant numbers without 
identifiable labels such as names, medical record number or social security number.
