Clinical trial NCT02520518
Conditions: Weight Loss
Sponsor: Christopher Bell
Start date: 2015-08-01; Completion date: 2017-05-01
Enrollment: 9 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
Th mechanism of action of dapagliflozin is via sodium-glucose co-transporter 2 (SGLT2) inhibition. Sodium-glucose co-transporter 2 inhibition is associated with moderate weight (fat) loss, in addition to other health benefits, including decreased blood pressure, decreased inflammation, and decreased oxidative stress. It is unclear as to whether these health benefits are due to SGLT2 inhibition per se, or as a secondary effect of weight loss.

Detailed description:
This is a randomized, prospective, placebo-controlled, double-blind, repeated measures study. 92 overweight/obese adults (body mas index \> 27.5 kg/m\^2) will be recruited for participation and randomly assigned to one of four 12 week treatments: 1) daily oral administration of dapagliflozin with ad-libitum dietary intake; 2) daily oral administration of dapagliflozin with supplemented dietary intake to achieve weight maintenance; 3) daily oral administration of a placebo plus dietary restriction such that weight loss is matched to participants in treatment 1; or, 4) daily oral administration of a placebo with ad-libitum dietary intake.

Arms: arm 1: Daily oral administration of dapagliflozin with ad libitum dietary intake. The dose of dapagliflozin will begin as one 5 mg tablet per day for the first 14-days. In the absence of complications, side effects, or unfavorable reactions, the dose will then increase to two 5 mg tablets per day for the remainder of the study. arm 2: Daily oral administration of dapagliflozin with supplemented dietary intake to achieve weight maintenance. The dose of dapagliflozin will begin as one 5 mg tablet per day for the first 14-days. In the absence of complications, side effects, or unfavorable reactions, the dose will then increase to two 5 mg tablets per day for the remainder of the study. arm 3: Daily oral administration of a placebo with ad-libitum dietary intake. Matching placebo for dapagliflozin 5 mg will begin as one tablet per day for the first 14-days. In the absence of complications, side effects, or unfavorable reactions, the dose will then increase to two tablets for the remainder of the study. arm 4: Daily oral administration of a placebo plus dietary restriction such that weight loss is matched to participants in Arm 1. Matching placebo for dapagliflozin 5 mg will begin as one tablet per day for the first 14-days. In the absence of complications, side effects, or unfavorable reactions, the dose will then increase to two tablets for the remainder of the study.
Interventions: intervention 1: Dapagliflozin intervention 2: Placebo intervention 3: Weight maintenance intervention 4: Ad libitum dietary intake intervention 5: Dietary restriction
Intervention descriptions: intervention 1: None intervention 2: None intervention 3: None intervention 4: None intervention 5: None

Amendment (1. Complete this one-page form, 2.  Update the sections of your protocol that you are requesting to
amend, 3. Electronically "sign" your application by clicking the check box on the Obligations page, 4. Remember
to click "Submit Form" so that the IRB administrators receive your request.)
 
  
  
1. 
Summarize the proposed changes to the protocol in lay terms.
The purpose of our study is to determine: 1) if the health benefits associated with Dapagliflozin
are due to Dapagliflozin per se, or as a secondary effect of weight loss; 2) if during weight loss
associated with use of Dapagliflozin, normal control of hunger and appetite is maintained.
Based on the results we have collected so far, we have learned that Dapagliflozin by itself does
not seem to cause much weight loss in healthy people who have good control of their blood
sugar (i.e. free from Diabetes).  Accordingly, we have decided to end the study early and
replace it with a new study.  In this regard, we would welcome your opinion and suggested edits
to our draft participant letter.  Our plan is to speak with all subjects in person, but also provide
the attached letter for the participants' own reference.
All subjects will be withdrawn from participation on receipt of your approval.

Does Dapagliflozin Promote Favorable Health Benefits That Are Independent Of Weight Loss?
Clinical Research Protocol Title: Dapagliflozin  Promotes Favorable Health Benefits That Are Independent
Of Weight Loss In Overweight/Obese Adults
 
      Complete Sections 1 - 16. Specify N/A as appropriate. Do not leave any required sections blank.
1. Purpose of the study
a)
Provide a brief lay summary of the project in <200 words.  The lay summary should be readily
understandable to the general public, and is, for example, what would be released to a newspaper if
requested.
Dapagliflozin is a new medicine to treat diabetes.  Its mechanism of action is via sodium-glucose co-
transporter 2 (SGLT2) inhibition.  Sodium-glucose co-transporter 2 inhibition is associated with moderate
weight (fat) loss, in addition to other health benefits, including decreased blood pressure, decreased
inflammation, and decreased oxidative stress. It is unclear as to whether these health benefits are due to
SGLT2 inhibition per se, or as a secondary effect of weight loss.
 
b)
What does the Investigator(s) hope to learn from the study?
We wish to learn if:
1.  Dapagliflozin (SGLT2 inhibition) promotes favorable health benefits that are independent of weight loss.
and if,
2. Weight loss associated with use of  Dapagliflozin (SGLT2 inhibition) is characterized by normal
circulating satiety signals rather than the usual diet-induced changes in circulating peptides that increase
hunger and reduce satiety.
 
c)
Proposed Start Date (may not precede IRB approval date):
On receipt of IRB approval (and FDA approval of IND application).
 
2. 
Study Procedures (If this is a student project, the methods section of the thesis or dissertation proposal
must be attached in section #16 - Attachment section.)
 
a)
In lay language, describe all the procedures, from screening through end-of-study, that the human subject
must undergo in the research project, including study visits, drug treatments, randomization and the
procedures that are part of standard of care.  Please note: Do NOT respond "See Attachment Section." If
you would like to add tables, charts, etc., attach those files in the Attachment section (#16).
OVERVIEW
This is a randomized, prospective, placebo-controlled, single-blind, repeated measures study.  92
overweight/obese adults (body mass index > 27.5 kg/m^2) will be recruited for participation and randomly
assigned to one of four 12 week treatments: 1) daily oral administration of  Dapagliflozin with ad libitum
dietary intake; 2) daily oral administration of  Dapagliflozin with dietary intake necessary to maintain
baseline body weight; 3) daily oral administration of a placebo plus reduced dietary intake such that weight
loss is similar to participants in treatment 1; or, 4) daily oral administration of a placebo with ad libitum
dietary intake.
Study participants will report to the research facilities on the Colorado State University main campus on 29
occasions.  Five of the 29 visits will be for screening, baseline, and post-intervention testing, while the


Page 9 of 32
 
other 24 visits will be for obtaining body weights twice weekly and for nutrition counseling.  The nutrition
counseling will not require additional visits to campus, but will occur on weigh-in days.
Visit 1: study participants will undergo screening: medical history, 12-lead electrocardiogram and blood
pressure assessment at rest and during incremental exercise to volitional exhaustion, blood sampling, and
measurement of body composition. The study participants  will be given a form in which they will record the
amounts of food and beverage intake for three days.  They will return this completed food record to the
research team.  This information will be useful for the nutrition counselor to understand the participant's
current eating habits and to provide nutritional recommendations.
Visit 2: Resting Metabolic Rate (RMR )and blood pressure will be measured, and a oral glucose tolerance
test will be performed.
Visit 3: appetite and hunger will be assessed
Visits 4-27: Twice weekly weigh-ins and nutrition counseling over the 12-weeks as needed to achieve the
assigned body weight goals. Concurrently during this twelve week period, research participants will ingest,
on a daily basis, either Dapagliflozin or placebo, depending on group assignment. During the invention
period , subjects will be assigned to a nutrition counselor with whom they will meet twice weekly for weigh-
ins and, as needed, to discuss strategies to meet the participant's assigned weight loss or weight
maintenance goals.
Visit 28:  your resting metabolic rate (RMR) will be measured, blood pressure will be measured, and an
oral glucose tolerance test (OGTT) will be performed.
Visit 29: in the HPCRL appetite and hunger will be assessed this visit will occur in week 12  (e.g. after the
final week of daily ingestion of Dapagliflozin).  Body composition will be measured at this visit or early the
following week, i.e. week 13.
DETAILED DESCRIPTION OF STUDY PROCEDURES
Visit 1: study participants will provide informed consent and undergo screening: medical history, 12-lead
electrocardiogram and blood pressure assessment at rest and during incremental exercise to volitional
exhaustion, blood sampling, and measurement of body composition.
These screening procedures are standard for our lab.  Each of the procedures is currently active in other
IRB-approved protocols (e.g. 12-3767H, 08-611H, 14-4756H).
Health History - Potential participants will complete a standardized health history questionnaire that will
address past and present medication use, allergies, past and present medical conditions and physical
injuries, and habitual use of alcohol and tobacco.
Body composition - Percent body-fat, fat-free mass, total and regional adipose tissue mass, and total bone
mineral density will be determined using a whole-body dual energy x-ray absorptiometry scan (DEXA,
Model DPX-IQ Lunar Corp., Madison, WI).
Maximal graded exercise stress testing - A 12-lead ECG, arterial blood pressure (brachial
sphygmomanometer) will be obtained during quiet resting conditions in the supine and upright sitting
positions, and during incremental stationary cycle ergometer or treadmill exercise until volitional fatigue.
During exercise, oxygen consumption, carbon dioxide production and ventilation may be determined by
indirect calorimetry.  All data from these tests will be will be reviewed by a cardiologist.  Only those
subjects demonstrating no signs or symptoms of disease will be invited to participate in the study.
Blood sampling – Blood (~ 20 ml) will be sampled from an antecubital or hand vein for subsequent analysis
of circulating factors pertinent to inclusion/exclusion criteria, including glucose, aspartate
aminotransferase, alanine aminotransferase,and  total bilirubin.  These blood analyses will be performed in
on-site (Piccolo Xpress, Abaxis, Union City, CA). Testing for Hepatitis B/C will be performed at a local,
external clinical lab (e.g. University of Colorado-Health North).  Per the Medical Monitor’s discretion follow
up blood draws maybe requested.
Visit 2: Resting Metabolic Rate (ventilated hood technique,indirect calorimetry) for 45 minutes and blood
pressure will be measured. An oral glucose tolerance test will be performed.
These procedures are standard for our lab.  Each of the procedures is currently active in other IRB-
approved protocols (e.g. 14-5201H).
Blood pressure will be determined three times using the left arm via standard procedures. Each
assessment will be separated by 3 minutes. The mean of the three measurements will be recorded.

Participants will report to the laboratory early in the morning, following a 12-hour fast and 24-hour
abstention from exercise. An intravenous catheter will be inserted into an antecubital or hand vein and kept
patent with a saline drip.  Following baseline blood sampling for fasting glucose and insulin, participants
will ingest 75 g of dextrose dissolved in 250 ml of water over 10-minutes.  Venous blood (~ 9 ml) will be
sampled at time 0 (baseline) and 5, 10, 15, 20, 30, 45, 60, 75, 90 105 and 120 minutes for determination of
concentration of blood glucose (2300 STAT Plus Glucose Lactate Analyzer, YSI Inc., Yellow Springs,
Ohio), and insulin (commercially available assay).
Prior to the start of the oral glucose tolerance test, venous blood (~ 20 ml) will be sampled, and
plasma/serum and red cells isolated and stored at -70°C for subsequent analysis of circulating markers of
inflammation (High sensitive C-Reactive Protein, Tumor Necrosis Factor Alpha, and Interleukin 6) and
oxidative stress (oxidized low density lipoprotein concentration, and thiobarbituric acid reactive
substances).
Visit 3: Appetite and hunger will be assessed.
These procedures are standard for our lab.  Each of the procedures is currently active in other IRB-
approved protocols (e.g. 12-3567H).
On a day different to the oral glucose tolerance day, participants will report to the laboratory early in the
morning, following a 12-hour fast and 24-hour abstention from exercise. An intravenous catheter will be
inserted into an antecubital or hand vein and kept patent with a saline drip. Participants will be provided
with a standardized “priming meal” comprising a commercially available, mixed-nutrient liquid meal, dosed
to 1 kcal per kg body mass (Ensure, Ross Laboratories, Abbott Park, IL; 64% CHO, 22% fat, 14% protein).
One hour following consumption of this priming meal, participants will be presented with a pre-weighed
buffet of food from which they will have opportunity to eat ad libitum quantities over a 30 minute period.
The remaining uneaten food will be reweighed and participants’ energy and macronutrient intakes will later
be determined using the Food Intake Analysis System software (U Texas Health Sciences Center,
Houston). Prior to the standardized primer meal, and to the buffet, and then every 60 minutes over 3 hours
following the buffet, participants will be asked to rate their perceptions of hunger and satiety using a visual
analog scale. At these same time points, venous blood (~ 20 ml) will be sampled, and plasma/serum
isolated and stored at -70°C for subsequent determination of concentrations of hunger and satiety
hormones (e.g. ghrelin, peptide YY, leptin, and insulin).
Visits 4-27: Research participants will undergo twice weekly measurement of body weight wearing the
same light indoor clothing on each occasion. During the first month of the 3-month intervention during
these weigh-ins, participants will receive weekly individualized diet counseling by a trained professional or
student in the Department of Food Science and Human Nutrition.  More counseling will be provided at
subsequent weigh-ins on an as-needed basis to enable participants to achieve their body weight goals (3-
4 kg weight loss in two of the groups, weight maintenance in the other two groups).  During this twelve
week period, participants will daily ingest either dapagliflozin or placebo.  During the first two weeks of the
12 week intervention, participants will ingest one pill daily (5 mg DAPA) and for the remaining 10 weeks
participants will ingest 2 pills daily (a total of 10 mg DAPA). On 3 random weigh-in occasions between
weeks 4 and 10, participants will be asked to recall what theyu ate during the previous 24 hours.
Visit 28:  Resting Metabolic Rate Test, Oral Glucose Tolerance Test, and Blood Pressure will be measured
(e.g. the final week of daily ingestion of Dapagliflozin). See description of Visit 2.
Visit 29: in the HPCRL appetite and hunger will be assessed this visit will occur in week 12  (e.g. after the
final week of daily ingestion of Dapagliflozin).  Body composition will be measured at this visit or early the
following week (e.g. week 13).
 
b)
Explain why human subjects must be used for this project.
Dapagliflozin is approved for human use.  Due to potential species differences it would not be appropriate
to perform these studies on experimental animals.
 
c)
Alternative Procedures. If the proposed study is a clinical trial of a drug, vaccine, device or treatment,
describe alternative procedures, if any, that might be advantageous to the subject. Describe the important
potential risks and benefits associated with the alternative procedure(s) or course(s) of treatment. Any
standard treatment that is being withheld must be disclosed. This information must be included in the
consent form.


Page 11 of 32
 
There are no appropriate alternative procedures.
 
d)
If the proposed study is a clinical trial of a drug, vaccine, device or treatment, will it be possible to continue
the more (most) appropriate therapy for the subject(s) after the conclusion of the study?
Not applicable.
 
e)
Study Endpoint. If the proposed study is a clinical trial of a drug, vaccine, device or treatment, what are the
guidelines or end points by which you can evaluate the alternative treatments during the study? If one
treatment proves to be clearly more effective than another (or others) will the study be terminated before
the projected total subject population has been enrolled? When will the study end if no important
differences are detected?
Not applicable.
 
f)
State if deception will be used. If so, provide a rationale and describe debriefing procedures. Submit a
debriefing script in the Attachment Section (#16).
There will be no deception.  Subjects may receive Dapagliflozin or a placebo; they will not know which
treatment (Dapagliflozin or placebo) they receive until study completion.
 
3. Background
a)
Describe past experimental and/or clinical findings leading to the formulation of the study, if applicable.
Aside from the metabolic benefits pertaining to glucose control, inhibition of sodium-glucose co-transporter
2 (SGLT2) is associated with moderate weight loss (Tahrani et al., 2011; Chen & Leung, 2013), with some
studies reporting up to 4.5 kg decreases in body mass over 12 weeks (Wilding et al., 2009). Animal data
are consistent with these observations (Devenny et al., 2012; Liang et al., 2012). SGLT2 inhibition is also
associated with other health benefits, including decreased blood pressure (Ferrannini et al., 2010; Dobbins
et al., 2012), decreased inflammation (Chen et al., 2012; Tahara et al., 2013, 2014), and decreased
oxidative stress (Tahara et al., 2013, 2014)—all health benefits with very important implications for
improved physiological function and decreased disease-risk. At present, it is unclear as to whether these
health benefits are due to SGLT2 inhibition per se, or as a secondary effect of weight loss.
Noteworthy, the weight loss associated with SGLT2 inhibition is not mediated by intentional dietary
restriction/intervention.  It is more likely to be mediated by the caloric loss associated with the decreased
renal tubular reabsorption of glucose, leading to urinary glucose excretions ranging between 45 and 80
g/day (180-320 kcal/d), depending on the drug dose (Idris & Donnelly, 2009). This caloric deficit is not
trivial. Typically, caloric deficits of this magnitude require either increased physical activity and/or dietary
restriction. The limitations of the use of dietary restriction for weight loss and, perhaps more importantly,
sustained lower weight maintenance, are well described (MacLean et al., 2006; Strohacker et al., 2014). In
response to diet-induced weight loss several biological factors, including increased appetite owing to
elevation of the orexigenic hormone, ghrelin, and decreased anorexigenic hormones like peptide YY
(PYY), promote increased dietary intake and subsequently weight re-gain. However, it is biologically
plausible that the weight loss accompanying SGLT2 inhibition may not be accompanied by increased
appetite as the unique mechanism of action allows the patient to consume/ingest calories (carbohydrates),
but limits the ability for internal storage. That is, during eating, nutrient sensors within the gut release
satiety factors to inhibit further dietary intake (Schaeffer et al., 2014; Strohacker et al., 2014). Ingesting
calories as carbohydrates while using SGLT2 inhibitors may allow for normal satiety signaling while limiting
caloric storage, thus thwarting biological impediments to long-term weight loss.
Accordingly, in light of the rationale provided, we wish to determine: 1) if the health benefits associated
with SGLT2 inhibition are due to SGLT2 inhibition per se, or as a secondary effect of weight loss; 2) if
during weight loss associated with SGLT2 inhibition, normal satiety signals are is maintained. This
information has important implications for the potential use of SGLT2 inhibition as a method of facilitating
sustained weight loss.

8.  
Subject Population - In the space below, please detail the participants that you are requesting to recruit
(include requested participant number and description of each group requested).  (Input N/A if not
applicable)
a)
Requested Participant Description (Include number of participants that you plan to study and description of
each group requested, if applicable).
92 overweight/obese adult volunteers (men and women) will complete the study.  However, the number
enrolled may be higher in the event of enrollment of replacement subjects for dropout(s) that discontinued
for reasons other than an adverse event due to study medication. In the event of a replacement subject
being enrolled, this subject will complete all visits.
 
b)
What is the rationale for studying the requested group(s) of participants?
Adults who are overweight/obese are at the greatest risk of developing type 2 diabetes, thus
overweight/obese adults potentially have the most to gain should the outcome of the study prove
favorable.  Inclusion of adults already diagnosed with diabetes might complicate the interpretation of the
data; that is, as a consequence of the patho-physiology associated with diabetes, the response to our
feeding treatment with or without Dapagliflozin may differ in adults with diabetes compared with adults who
are diabetes free.
 
c)
If applicable, state the rationale for involvement of potentially vulnerable subjects to be entered into the
study, including minors, pregnant women, economically and educationally disadvantaged, or decisionally
impaired subjects. Specify the measures being taken to minimize the risks and the chance of harm to the


Page 15 of 32
 
impaired subjects. Specify the measures being taken to minimize the risks and the chance of harm to the
potentially vulnerable subjects.
Potentially vulnerable subjects will not be studied.
 
d)
If women, minorities, or minors are not included, a clear compelling rationale must be provided. Examples
for not including minors: disease does not occur in children; drug or device would interfere with normal
growth and development; etc.
Women and minorities will be invited to participate.  Minors will be excluded.  The prevalence of type 2
diabetes is greater in adults than minors.  Safety and effectiveness of Dapagliflozin in pediatric patients
under 18 years of age have not been established.
 
e)
State if any of the subjects are students, employees, or laboratory personnel. They should be presented
with the same written informed consent. If compensation is allowed, they should also receive it.
If any of the subjects are students, employees, or laboratory personnel they will be presented with the
same written informed consent; compensation is allowed, they will also receive it.
 
f) 
Describe how potential subjects will be identified for recruitment (e.g., chart review, referral from individual's
treating physician, those individuals answering an ad). How will potential participants learn about the
research and how will they be recruited (e.g., flyer, email, web posting, telephone, etc.)? Attach recruitment
materials in the Attachment Section (#16). Important to remember: potential subjects may not be contacted
before IRB approval.
Please see examples of recruitment materials in the attachment section.
Potential subjects will be recruited via electronic advertisement (e.g. The Source) and email lists (e.g. CSU
genfac).  If necessary, potential subjects may also be recruited via newspaper advertisement (e.g. The
Coloradoan), clinical trials websites (e.g. clinicaltrials.gov), and/or flyers/posters placed in public places
(e.g. coffee shops) in and around the Fort Collins area.
 
g) 
If applicable, provide rationale for the inclusion of healthy volunteers in this study. Specify any risks to
which these healthy volunteers may possibly be exposed. Specify the measures being taken to minimize
the risks and the chance of harm to these volunteers.
Adults who are overweight/obese but otherwise healthy will be invited to participate.  Inclusion of adults
already diagnosed with diabetes might complicate the interpretation of the data; that is, as a consequence
of the patho-physiology associated with diabetes, the response to feeding with or without Dapagliflozin
may differ in adults with diabetes compared with adults who are diabetes free.
It is not possible to identify all potential risks in research procedures, but the researcher(s) have taken
reasonable safeguards to minimize any known and potential (but unknown) risks.  The Human
Performance Clinical Research Laboratory has emergency supplies including a medicine trolley equipped
with heart machines and supplemental oxygen.  The research team has a great deal of experience with all
of the procedures.  Some of the procedures for which you are being asked to volunteer have a number of
associated risks:
Body Composition
The risks associated with the DEXA are very low.  The maximum radiation dose you will receive in this
study is less than 1/1000th of the federal and state occupational whole body dose limit allowed to radiation
workers (5,000 mrem).  Put another way, the maximum dose from any scan we utilize with this DEXA
ranges from 1.2 mrem (Whole body scan) to 12.2 mrem (for several of the regional scans, such as lumbar,
femur, and forearm scans).  The average annual background radiation you already receive is at least 620
mrem/year.  The more radiation you receive over the course of your life, the more the risk increases of
developing a fatal cancer or inducing changes in genes.  The radiation in this scan is not expected to
significantly increase these risks, but the exact increase in such risks is not known.  There are no
discomforts associated with this procedure. Women who are or could be pregnant should receive no
unnecessary radiation and should not participate in this study.
Women will complete a pregnancy test before participating in a DEXA scan.
Exercise Tests
There is a very small chance of an irregular heartbeat during exercise (< 1% of all subjects).  Other rare
risks of a stress test are heart attack (< 5 in 10,000) and death (<2 in 10,000).  Wearing a mouthpiece and
nose-clip can sometimes cause dryness in the mouth and mild discomfort. Difficult exercise may make you


Page 16 of 32
 
feel very tired, light headed and nauseous.  Exhausting exercise will, by definition, make you feel very
tired.  After any exercise your muscles might ache.
ACSM guidelines pertinent to the requirement of physician supervised exercise (stress) testing will be
followed.
Blood Collection
When the needle goes into a vein, it may hurt for a short period of time (a few seconds).  Also there may
be minor discomfort of having the needle/plastic tube taped to your arm.  In about 1 in 10 cases, a small
amount of bleeding will occur under the skin that will cause a bruise.  The risk of forming a blood clot in the
vein is about 1 in 100, and the risk of significant blood loss is 1 in 1,000.  Additionally, there is a risk that
you may faint while having blood collected or having the catheter inserted in your vein.
Only trained research personnel will be permitted to perform phlebotomy.

Participants are provided with the following information in the consent form: "If you complete all of the
visits, and all of the procedures as described for the entire study, you will receive up to $400 in total
compensation. $300 will be paid in installments and prorated as follows: you will not receive compensation
for visit 1 (the screening visit). You will receive $60 following completion of baseline testing (visits 2, and
3).  After successfully completing 8 weeks of the intervention you will receive $60; after compleiting12
weeks you will receive $60. You will receive $60 for completion of visit 28, and $60 for completion of visit
29. If you are at least 95% compliant in terms of both visits and pill ingestion, you will receive an additional
$100.
Should your participation in the study end early, you will still receive feedback pertaining to your health and
fitness."
 
l)

m)
Estimate the probable duration of the entire study. This estimate should include the total time each subject
is to be involved and the duration the data about the subject is to be collected (e.g., This is a 2-year study.
Participants will be interviewed 3 times per year; each interview will last approximately 2 hours.  Total
approximate time commitment for participants is 12 hours).  These times should be consistent with the time
commitment listed on the consent document.
The study will take place over approximately 3 years.  Subjects will be involved only for approximately 4
months and will be asked to visit the Human Performance Clinical Research Laboratory and/or Nutrition
and Metabolic Fitness Laboratory in the Gifford Building at CSU on 29 different occasions.  Visits will last
between 30 minutes and 5 hours.

9. Risks (Input N/A if not applicable)
     
US Department of Health & Human Services (HHS) Regulations define a subject at risk as follows: "...any
individual who may be exposed to the possibility of injury, including physical, psychological, or social injury,
as a consequence of participation as a subject in any research, development, or related activity which
departs from the application of those accepted methods necessary to meet his needs, or which increases
the ordinary risks of daily life, including the recognized risks inherent in a chosen occupation or field of
service."
 
 a) 
PI's evaluation of the overall level of Risk. (Please check one: minimal or > minimal.)
Minimal (everyday living)
Y
> Minimal (greater than everyday living)
 
 b)   
For the following categories include a scientific estimate of the frequency, severity, and reversibility of
potential risks. Wherever possible, include statistical incidence of complications and the mortality rate of
proposed procedures. Where there has been insufficient time to accumulate significant data ON risk, a
statement to this effect should be included. (In describing these risks in the consent form to the subject, it is
helpful to use comparisons which are meaningful to persons unfamiliar with medical terminology.) Address
any risks related to:
 
 
   
   
1.   
Use of investigational devices. Please include the clinical adverse events (AEs) associated with
each of the devices with an indication of frequency, severity and reversibility. This information
can often be found in the Investigator(s) brochure.
N/A
 
 
   
   
2   
Use of investigational drugs. Please include the clinical AEs associated with each of the drugs
with an indication of frequency, severity and reversibility. This information can often be found in
the Investigator(s) brochure.
N/A
 
 
   
   
3   
Use of commercially available drugs, reagents or chemicals. Please include the clinical AEs
associated with each of the drugs with an indication of frequency, severity and reversibility. This
information can often be found in the package insert provided by the manufacturer.
Please see the package insert provided by the manufacturer for further information.
Adverse reactions in placebo-controlled studies reported in more than 2% but less than 8.5 %
of patients treated with Dapagliflozin include:


Page 19 of 32
 
•Female genital mycotic infections, such as (listed in order of frequency reported): vulvovaginal
mycotic infection, vaginal infection, vulvovaginal candidiasis, vulvovaginitis, genital infection,
genital candidiasis, fungal genital infection, vulvitis, genitourinary tract infection, vulval abscess,
and vaginitis bacterial.
•Nasopharyngitis (cold-like symptoms)
•Urinary tract infections, such as (listed in order of frequency reported): urinary tract infection,
cystitis, Escherichia urinary tract infection, genitourinary tract infection, pyelonephritis, trigonitis,
urethritis, kidney infection, and prostatitis.
•Back pain
•Increased urination
•Male genital mycotic infections, such as (listed in order of frequency reported): balanitis, fungal
genital infection, balanitis candida, genital candidiasis, genital infection male, penile infection,
balanoposthitis, balanoposthitis infective, genital infection, and posthitis.
•Influenza
•Nausea
•Dyslipidemia
•Constipation
•Discomfort with urination
•Pain in extremity
In addition, use of Dapagliflozin is also associated with a risk of weight loss (up to 10 lbs over
12 weeks).
 
 
   
   
4   
When performing procedures, please include all investigational, non-investigational and non-
invasive procedures (e.g., surgery, blood draws, treadmill tests).
Subjects are provided with the following information pertaining to risks:
Body Composition
The risks associated with the DEXA are very low.  The maximum radiation dose you will receive
in this study is less than 1/1000th of the federal and state occupational whole body dose limit
allowed to radiation workers (5,000 mrem).  Put another way, the maximum dose from any scan
we utilize with this DEXA ranges from 1.2 mrem (Whole body scan) to 12.2 mrem (for several of
the regional scans, such as lumbar, femur, and forearm scans).  The average annual
background radiation you already receive is at least 620 mrem/year.  The more radiation you
receive over the course of your life, the more the risk increases of developing a fatal cancer or
inducing changes in genes.  The radiation in this scan is not expected to significantly increase
these risks, but the exact increase in such risks is not known.  There are no discomforts
associated with this procedure. Women who are or could be pregnant should receive no
unnecessary radiation and should not participate in this study.
Exercise Tests
There is a very small chance of an irregular heartbeat during exercise (< 1% of all subjects).
Other rare risks of a stress test are heart attack (< 5 in 10,000) and death (<2 in 10,000).
Wearing a mouthpiece and nose-clip can sometimes cause dryness in the mouth and mild
discomfort. Difficult exercise may make you feel very tired, light headed and nauseous.
Exhausting exercise will, by definition, make you feel very tired.  After any exercise your
muscles might ache.
Blood Collection
When the needle goes into a vein, it may hurt for a short period of time (a few seconds).  Also
there may be minor discomfort of having the needle/plastic tube taped to your arm.  In about 1
in 10 cases, a small amount of bleeding will occur under the skin that will cause a bruise.  The
risk of forming a blood clot in the vein is about 1 in 100, and the risk of significant blood loss is 1


Page 20 of 32
 
in 1,000.  Additionally, there is a risk that you may faint while having blood collected or having
the catheter inserted in your vein.
Resting Metabolic Rate
The risks associated with this measurement are very low.  Some people might feel
claustrophobic (fear of small places) when the bubble is placed over their head.  The bubble is
clear (see-through) and ventilated (room air is pumped through it).  The bubble is also very,
very light and easy to remove.
 
 
   
   
5  
Radioisotopes/radiation-producing machines(e.g., X-rays, CT scans, fluoroscopy).
Body Composition
The risks associated with the DEXA are very low.  The maximum radiation dose you will receive
in this study is less than 1/1000th of the federal and state occupational whole body dose limit
allowed to radiation workers (5,000 mrem).  Put another way, the maximum dose from any scan

11. Procedures to Maintain Confidentiality
a)
Describe the procedures that protect the privacy of the subjects and maintain the confidentiality of the data.
If a linked list is used, explain when the linked list will be destroyed.  Provide a sample of the code that will
be used, if applicable.
Participants will be identified only on a signed consent form and initial screening form that will be kept
locked and separate from other research data. Each subject will be assigned a randomly generated code
(e.g. 12698afd) that will be used to identify them in association with all other research data and blood or
tissue samples. Records identifying individuals will be kept in Dr. Bell’s office/laboratory in a locked cabinet
and will be destroyed (shredded) following completion/publication of the project. Data will only be released
to regulatory/governmental entities authorized to inspect research records, such as the FDA.
 
b)
If information derived from the study will be provided to the subject's personal physician, a government
agency, or any other person or group (other than the research team), describe to whom the information will
be given and the nature of the information, if applicable.
Unless ordered by an agent of the law, no information will be shared specific to a subject without that
subject's written permission. Anonymous data will only be released to regulatory/governmental entities
authorized to inspect research records, such as the FDA.
 
c)
Specify where and under what conditions study data will be kept, how samples will be labeled, who has
access to the data, and what will be available and to whom.  Federal regulations require that study data
and consent documents be kept for a minimum of three (3) years after the completion of the study by the
PI.  For longitudinal projects and federally regulated studies, the PI may be required to keep the data and
documents for a longer time period.
Research records and data will be stored on file in locked cabinets in Dr. Bell’s office/laboratory, or digitally
on a password protected central server. Only members of the research team will have access to these
records. The materials will be archived for a minimum of three years after completion of the project.

Obligations (Researcher's Responsibilities)
 
The Principal Investigator is ultimately responsible for the conduct of the project. Obligations of the Principal
Investigator are:
 
Conduct the research involving human subjects as presented in the protocol, including modifications, as
approved by the Department and Institutional Review Board. Changes in any aspect of the study (for example
project design, procedures, consent forms, advertising materials, additional key personnel or subject populations)
will be submitted to the IRB for approval before instituting the changes (PI will submit the "Amendment/Revision"
form);
 
Provide all subjects a copy of the signed consent form, if applicable. Investigators will be required to retain signed
consent documents for three (3) years after close of the study;
 
Maintain an approved status for Human Subjects Protection training. Training must be updated every three (3)
years (Contact RICRO to check your current approval/renewal dates). For more information:  Human Subjects
Training Completed?

WHY AM I BEING INVITED TO TAKE PART IN THIS RESEARCH? 
 
You are between 18-65 years, weigh more than you prefer (body mass index is greater 
than or equal to 27.5 kg/m2), free of diabetes, not be pregnant, and not performing more 
than 30 minutes 3 times per week of moderate exercise.  
 
WHO IS DOING THE STUDY?  
 
Drs. Bell and Melby are running the study; local medical doctors, other researchers, and 
a team of trained graduate and undergraduate students are helping.  AstraZeneca 
Pharmaceuticals LP, a company that makes medicine, is providing financial support for 
the study.   
 
WHAT IS THE PURPOSE OF THIS STUDY?  
 
Dapagliflozin (commercially available as Farxiga; pronounced: far-see-gah) is a new 
medicine for treating type 2 diabetes.  Use of Dapagliflozin is associated with moderate 
weight loss, in addition to other health benefits, including decreased blood pressure, 
and decreased concentration of substances in the blood that are indicative of disease 
risk (inflammation and oxidative stress). It is unclear as to whether these health benefits 
are due to Dapagliflozin per se, or as a secondary effect of weight loss.  The purpose of 
the study is to determine: 1) if the health benefits associated with Dapagliflozin are due 
to Dapagliflozin per se, or as a secondary effect of weight loss; 2) if during weight loss 
associated with use of Dapagliflozin, normal control of hunger and appetite is 
maintained. 
WHERE IS THE STUDY GOING TO TAKE PLACE AND HOW LONG WILL IT LAST?  
 
The study will take place in the Human Performance Clinical Research Laboratory 
(HPCRL) in the Department of Health and Exercise Science, and Nutrition and Fitness

Laboratory in the Gifford Academic Building, Department of Food Science and Human 
Nutrition, on the main campus of Colorado State University (CSU), Fort Collins. 
 
The study will take place over approximately 3 years. You will be involved for 
approximately 4 months and will be asked to visit the labs 2-3 times per week over 14 
weeks. 
 
WHAT WILL I BE ASKED TO DO? 
 
Here is a brief summary of what you will be asked to do: 
 
Visit 1: in the HPCRL you will undergo screening: medical history, 12-lead 
electrocardiogram (ECG) and blood pressure assessment at rest and during 
incremental exercise to volitional exhaustion, blood sampling, and measurement of 
body composition. You will be given a form in which you will record the amounts of food 
and beverage intake for three days.  You will return this completed food record to the 
research team.  This information will be useful for the nutrition counselor to understand 
your current eating habits and to provide nutritional recommendations.  
 
Visit 2: in the HPCRL, your resting metabolic rate (RMR) will be measured, blood 
pressure will be measured, and an oral glucose tolerance test (OGTT) will be 
performed. 
 
Visit 3: in the HPCRL appetite and hunger will be assessed 
 
Visits 4-27: During the 12 weeks of treatment you will swallow, on a daily basis, either 
Dapagliflozin or placebo. During that time, you will be assigned to a nutrition counselor 
with whom you will meet twice weekly for weigh-ins and, as needed, to discuss 
strategies to meet your assigned weight loss or weight maintenance goals. You will 
need to fast for 10 hours prior to each weigh-in, so these meetings typically take place 
during the morning hours. During these nutrition counseling sessions you will be asked 
to participate in a variety of educational activities to help meet your assigned goal, such 
as how to accurately determine food portion sizes.  
 
Visit 28: in the HPCRL your resting metabolic rate (RMR) will be measured, blood 
pressure will be measured, and an oral glucose tolerance test (OGTT) will be 
performed. This visit will occur in week 12 (e.g. the final week of daily ingestion of 
Dapagliflozin). 
 
Visit 29: in the HPCRL appetite and hunger will be assessed. This visit will occur in 
week 12 (during the final week of daily ingestion of Dapagliflozin). Body composition will 
be measured at this visit or the start of the following week (week 13).

Here is a detailed description of what you will be asked to do: 
 
Visit 1 – Screening Visit / Medical History / Stress Test / Blood Test / Body 
Composition 
 
The first visit to the Human Performance Clinical Research Lab (HPCRL) will be a 
screening visit. During this visit we will make sure that participation in this study is right 
for you. 
 
This screening visit will include the following procedures: 
 
Medical Questionnaire 
You will be asked to answer several pages of questions related to your health, any 
illness you may have or have had, and medications you use or have used in the past.  
 
Blood Pressure 
We will measure your blood pressure using a standard blood pressure cuff (the same as 
in a doctor's office). Blood pressure will be measured during all of the tests performed in 
the lab with the exception of body composition. There are no known risks associated 
with this procedure. (Duration: 5 minutes) 
 
Body Composition 
We will measure how much fat you have in your body using a test called dual energy x-
ray absorptiometry (DEXA). The DEXA test requires you to lie quietly on a padded table 
while a small probe gives off low-level x-rays and sends them over your entire body.  
This test gives very accurate measurements of your body fat and bone mineral density.  
We will also measure the circumference of your waist and hip using a tape measure. 
(Duration: ~ 15 minutes) 
 
Pregnancy Test (Women Only) 
Women who are or could be pregnant should not participate in this study. Before the 
body composition test(s) women will be asked to use a pregnancy test (urine test) to 
confirm they are not pregnant.    
 
Blood Test 
During this visit we will be taking blood from you. We will be taking approximately 20 ml 
(~1.5 tablespoons); this is a lot less than the amount that is typically taken when a

person donates blood. Your blood will be tested for various things to make sure you are 
healthy enough to consume Dapagliflozin. Your blood will be taken from veins in your 
arms or hands using needles and hollow plastic tubes called catheters. On the advice of 
the medical monitor (study physician), you may be asked to have your blood tested 
several more times during the treatment period to make sure the study is still right for 
you.  
 
Exercise Stress Test 
You will be asked to perform a vigorous exercise test.  This test will tell us if your heart 
is healthy. You will be asked to walk on a motorized treadmill or ride an exercise cycle 
(cycle ergometer) for approximately 10-15 minutes. The exercise will become more 
difficult every 2 minutes. While you are walking/riding we will measure your heart rate 
with an electrocardiogram (ECG) and your blood pressure with a cuff placed around 
your upper arm. We will also ask you to wear a nose clip (something that stops you 
breathing through your nose) and ask you to breathe through a mouthpiece. This will let 
us measure the gases you breathe. Depending on your age, a physician may supervise 
the test. If we do not think your heart is healthy you will be referred to your primary care 
physician for further testing. There is a chance that you may not be allowed to take part 
in our study. (Duration: ~ 60 minutes) 
 
Visit 2 – Resting Metabolic Rate Test, Oral Glucose Tolerance Test, and Blood 
Pressure 
 
These tests will take place early in the morning after a 12-hour fast, and 24-hour 
abstention from alcohol, caffeine, and exercise. You will be asked to wear a T-shirt. 
 
We will measure how your metabolism works (how many calories you burn) while you 
are resting. You will rest quietly on a bed for 10 minutes. After that time, we will place a 
clear plastic bubble (hood) over your head, through which you will be able to breath, 
and ask you to continue lying quietly for 45 minutes.  
 
We will measure your blood pressure using a standard blood pressure cuff (the same as 
in a doctor's office). We will do this three times.  
 
We will then perform the oral glucose tolerance test. You will then be asked to drink 
water (300 ml or ~ 10 oz) in approximately 5 minutes. A small amount of sugar (75 g of 
glucose) will have been added to the water. This will make it taste sweeter and also 
increase your blood sugar.   
 
After drinking the water you will sit/lie quietly for 2 hours. You will be able to read and/or 
watch TV and/or listen to music. We will collect blood from you over the 2 hours. Your 
blood will be analyzed for concentrations of sugar (glucose), insulin (something that 
helps control blood sugar), and other things that may be help control blood sugar. Your 
blood will be taken from veins in your arms or hands using needles and hollow plastic 
tubes called catheters. 
 
The whole visit will last approximately 3 hours.

Visit 3 – Appetite and Hunger Assessment 
 
This test will take place early in the morning after a 12-hour fast, and abstention from 
alcohol, caffeine, and exercise. You will be asked to wear a T-shirt. 
 
We will place a hollow plastic tube (a venous catheter) into a vein in your arm or hand.  
The tube will remain in your vein for approximately 5 hours. We will sample a very small 
amount of blood periodically, throughout the duration of the visit. The total amount of 
blood sampled will be approximately 100 ml, or 7 tablespoons. 
 
You will be given a liquid meal (an Energy Drink) to serve as “an appetizer” before you 
are given your main meal. One hour later you will be presented with a buffet style 
presentation of assorted foods and beverages. You will be able to eat as much, or as 
little as you like, of any or all of the foods and beverages.   
 
Throughout the visit (before the liquid meal, and before and after the main meal) you will 
be asked questions about your hunger and appetite.    
 
Visit 4-27 – 12 Weeks of Nutritional Counseling  
 
You will be randomly assigned to one of 4 Dapagliflozin/Placebo-Body Weight 
conditions described below (you will not be able to choose your condition nor will you 
know if you are assigned to take Dapagliflozin or the placebo): 
 
Condition 1) You will swallow Dapagliflozin every day and eat as you usually do.  Based 
on previous studies of Dapagliflozin and other similar medicine, you are likely to lose 
weight (possibly up to 10 lbs over 12 weeks). 
 
Condition 2) You will swallow Dapagliflozin every day and eat as you usually do, with 
the possibility of being asked to eat additional food containing carbohydrates (including 
things like potatoes, bread, pasta, rice, etc.).  The goal of this treatment is for you to not 
lose weight.  That is, you will try to maintain your weight. 
 
Condition 3) You will swallow a placebo (a pill that has no effect) every day.  You will be 
asked to eat fewer carbohydrates (like potatoes, bread, pasta, etc.) than you usually do. 
The goal of this treatment is for you to lose the same amount of weight as someone 
who swallows Dapagliflozin everyday (possibly up to 10 lbs over 12 weeks). 
 
Condition 4) You will swallow a placebo (a pill that has no effect) every day and eat as 
you usually do. The goal of this treatment is for you to not lose weight. That is, you will 
try to maintain your weight. 
 
You will receive instructions and training about what to eat and how much to eat 
depending on the condition to which you are assigned at your weekly meetings with a 
nutrition counselor. On 3 random weigh-in occasions between weeks 4 and 10, you will 
be asked to recall what you ate during the previous 24 hours.

You will be weighed twice per week in the Gifford Building. You will need to fast for 10 
hours prior to each weigh-in. If you fail to achieve your target body weight (within 1 kg or 
2.2 lbs) on three consecutive weighing sessions you will be provided with additional 
counseling and instruction to aid in achieving your target body weight. 
 
At the same time as Visits 4 – 27: Daily Ingestion of Dapagliflozin or Placebo 
During the 12 weeks of your study participation, you will swallow a pill every day. The 
pill may be Dapagliflozin or a placebo, a pill that has no effect. You will not know which 
pill you are swallowing.  If you are chosen to swallow Dapagliflozin, for the first 2 weeks 
the dose will be 5 mg/day. For the next 10 -weeks the dose will be 10 mg/day. For a 
description of Dapagliflozin, see below. 
 
If you fail to ingest 90% of your medication (75 of 84 total doses), you will be removed 
from the study.  
 
Visit 28 – Resting Metabolic Rate Test, Oral Glucose Tolerance Test, and Blood 
Pressure 
You will repeat the procedures described in visit 2. This visit will occur in week 12 (e.g. 
the final week of daily ingestion of Dapagliflozin).  
 
Visit 29 – Appetite and Hunger Assessment  
You will repeat the procedures described in visit 3. You will also undergo measurement 
of body composition (as described in visit 1). This visit will occur in week 12 (e.g. the 
final week of daily ingestion of Dapagliflozin). 
 
What is Dapagliflozin? 
Dapagliflozin is a new medicine that is used to treat people who have type 2 diabetes 
(high blood sugar and/or difficulty controlling blood sugar). Dapagliflozin works by 
limiting the body’s ability to absorb sugar from food and beverages.  It does this by 
changing the ability of the kidneys to absorb sugar.  The sugar that is not absorbed is 
removed from the body in urine. 
 
ARE THERE REASONS WHY I SHOULD NOT TAKE PART IN THIS STUDY?  
 
You will not be allowed to take part in the study for any of the following reasons: 
 
1. Evidence of serious (clinically significant) heart (cardiovascular), lung (respiratory), 
kidney (renal), liver (hepatic), stomach (gastrointestinal), blood (hematological), nerve 
(neurological), mental (psychiatric), or other disease, or if you have been hospitalized in 
the past 2 years as a result of these conditions, or are receiving medicine 
(pharmacological treatment) for these conditions. 
 
2. Use of prescription drugs (see exceptions listed below) or herbal preparations in the 
2 weeks before study commencement. Prior use of medication or herbal preparations in

the 4 weeks before study commencement that are intended for weight-loss and/or 
sold/marketed as weight-loss products or may alter metabolism. 
 
Permitted Prescription Drugs: 
• Birth Control  
• Less than a 7 day short course of antibiotics. Note: Rifampicin is not permitted. 
• Other medicines, such as those for GERD, depression, OTC analgesics and 
allergy medications may be allowed, but will be approved on a case-by-case 
basis. 
 
3. You are currently enrolled in another clinical study for another investigational drug or 
has taken any other investigational drug within 30 days before the screening visit. 
 
4. You are a smoker: Habitual and/or recent use (within 2 years) of tobacco. 
 
5. You are considered unsuitable for participation in this trial for any reason, as judged 
by the investigator or medical monitor. 
 
6. You have a history of serious hypersensitivity reaction to Dapagliflozin. 
 
7. You have severe kidney problems: renal impairment, end-stage renal disease, or 
dialysis. 
 
8. You are pregnant or breastfeeding.  
 
9. You have severe hepatic insufficiency and/or significant abnormal liver function 
based on blood tests. 
 
10. You have a history of bladder cancer. 
 
11. Your blood pressure during visit 1: Systolic blood pressure ≥165 mmHg and/or 
diastolic blood pressure ≥100 mmHg. 
 
12. Your blood pressure during visit 3: Systolic blood pressure ≥165 mmHg and/or 
diastolic blood pressure ≥100 mmHg 
 
13. Patients who, in the judgment of the medical doctor, may be at risk for dehydration. 
    
WHAT ARE THE POSSIBLE RISKS AND DISCOMFORTS?  
 
It is not possible to identify all potential risks in research procedures, but the 
researcher(s) have taken reasonable safeguards to minimize any known and potential 
(but unknown) risks. The Human Performance Clinical Research Laboratory has 
emergency supplies including a medicine trolley equipped with heart machines and 
supplemental oxygen. The research team has a great deal of experience with all of the

procedures. Some of the procedures for which you are being asked to volunteer have a 
number of associated risks: 
 
Body Composition 
The risks associated with the DEXA are very low. The maximum radiation dose you will 
receive in this study is less than 1/1000th of the federal and state occupational whole 
body dose limit allowed to radiation workers (5,000 mrem). Put another way, the 
maximum dose from any scan we utilize with this DEXA ranges from 1.2 mrem (Whole 
body scan) to 12.2 mrem (for several of the regional scans, such as lumbar, femur, and 
forearm scans). The average annual background radiation you already receive is at 
least 620 mrem/year. The more radiation you receive over the course of your life, the 
more the risk increases of developing a fatal cancer or inducing changes in genes.  The 
radiation in this scan is not expected to significantly increase these risks, but the exact 
increase in such risks is not known. There are no discomforts associated with this 
procedure. Women who are or could be pregnant should receive no unnecessary 
radiation and should not participate in this study. 
 
Exercise Test 
There is a very small chance of an irregular heartbeat during exercise (< 1% of all 
subjects). Other rare risks of a stress test are heart attack (< 5 in 10,000) and death (<2 
in 10,000). Wearing a mouthpiece and nose-clip can sometimes cause dryness in the 
mouth and mild discomfort. Difficult exercise may make you feel very tired, light headed 
and nauseous. Exhausting exercise will, by definition, make you feel very tired. After 
any exercise your muscles might ache. 
 
Blood Collection 
When the needle goes into a vein, it may hurt for a short period of time (a few seconds).  
Also there may be minor discomfort of having the needle/plastic tube taped to your arm.  
In about 1 in 10 cases, a small amount of bleeding will occur under the skin that will 
cause a bruise. The risk of forming a blood clot in the vein is about 1 in 100, and the risk 
of significant blood loss is 1 in 1,000. Additionally, there is a risk that you may faint while 
having blood collected or having the catheter inserted in your vein. 
 
Resting Metabolic Rate 
The risks associated with this measurement are very low. Some people might feel 
claustrophobic (fear of small places) when the bubble is placed over their head. The 
bubble is clear (see-through) and ventilated (room air is pumped through it). The bubble 
is also very, very light and easy to remove.  
 
Dapagliflozin 
Adverse reactions in placebo-controlled studies reported in more than 2% but less than 
8.5 % of patients treated with Dapagliflozin include:  
 
• Female genital mycotic infections (yeast or fungal infections), such as (listed in 
order of frequency reported): vulvovaginal mycotic infection, vaginal infection, 
vulvovaginal candidiasis, vulvovaginitis, genital infection, genital candidiasis,

fungal genital infection, vulvitis, genitourinary tract infection, vulval abscess, and 
vaginitis bacterial.  
 
• Nasopharyngitis (cold-like symptoms) 
 
• Urinary tract infections (UTIs), such as (listed in order of frequency reported): 
urinary tract infection, cystitis, Escherichia urinary tract infection, genitourinary 
tract infection, pyelonephritis, trigonitis, urethritis, kidney infection, and prostatitis. 
 
• Back pain 
 
• Increased urination 
 
• Male genital mycotic infections (yeast or fungal infections), such as (listed in order 
of frequency reported): balanitis, fungal genital infection, balanitis candida, genital 
candidiasis, genital infection male, penile infection, balanoposthitis, 
balanoposthitis infective, genital infection, and posthitis. 
 
• Influenza (Flu) 
 
• Nausea (Upset stomach) 
 
• Dyslipidemia (High Cholesterol) 
 
• Constipation 
 
• Discomfort with urination 
 
• Pain in extremity 
 
In a study of 5,936 patients with type 2 diabetes, one patient became ill with diabetic 
ketoacidosis (a metabolic sickness). If you experience any of the following 
sensations/symptoms you should seek immediate medical help and contact the 
investigator: sickly or queasy (nausea), vomiting, stomach (abdominal) pain, confusion, 
change in breathing pattern and unusual tiredness (fatigue) or sleepiness. 
 
In addition, use of Dapagliflozin is also associated with a risk of weight loss (up to 10 lbs 
over 12 weeks). 
 
ARE THERE ANY BENEFITS FROM TAKING PART IN THIS STUDY?  
 
There are no direct benefits in participating, however you will receive a copy of your 
results and information pertinent to your body composition (i.e. height and weight), and 
metabolic and cardiovascular risk factors. For example, in blood we will measure 
concentrations of glucose. You will be provided with a copy of your DEXA scan; you may 
wish to have this interpreted by a medically qualified professional. Finally, this study has

the potential to identify an additional benefit for people who use Dapagliflozin to treat 
their type 2 diabetes.   
 
DO I HAVE TO TAKE PART IN THE STUDY? 
 
Your participation in this research is voluntary. If you decide to participate in the study, 
you may withdraw your consent and stop participating at any time without penalty or 
loss of benefits to which you are otherwise entitled.   
 
WHAT WILL IT COST ME TO PARTICIPATE?  
 
Other than transport to and from the campus, your participation should incur no costs.   
 
WHO WILL SEE THE INFORMATION THAT I GIVE?  
 
We will keep private all research records that identify you, to the extent allowed by law.  
For this study, we will assign a code to your data (e.g. 1234ABCD) so that the only place 
your name will appear in our records is on the consent and in our data spreadsheet that 
links you to your code. Only the research team will have access to the link between you, 
your code, and your data. The only exceptions to this are if we are asked to share the 
records of the study for audit purposes with the Food and Drug Administration, Health 
and Human Services, AstraZeneca, and/or the CSU Institutional Review Board ethics 
committee, if necessary. In addition, for funded studies, the CSU financial management 
team may also request an audit of research expenditures. For financial audits, only the 
fact that you participated would be shared, not any research data. When we write about 
the study to share it with other researchers, we will write about the combined information 
we have gathered. You will not be identified in these written materials. We may publish 
the results of this study; however, we will keep your name and other identifying 
information private. 
 
Your identity/record of receiving compensation (NOT your data) may be made available 
to CSU officials for financial audits. 
 
CAN MY TAKING PART IN THE STUDY END EARLY?  
 
You will be weighed twice per week in the Gifford Building. If you fail to achieve your 
target body weight (within 1 kg or 2.2 lbs) on three consecutive weigh-in sessions you 
will be provided with additional counseling and instruction to aid in achieving your target 
body weight. If you fail to achieve your target body mass (within 1 kg or 2.2 lbs) over the 
course of the first eight weeks, you will be removed from the study. If you fail to ingest 
90% of your Dapagliflozin or placebo (75 of 84 total doses), you will be removed from 
the study. Your participation in the study will end if you become pregnant. We ask that, 
in the event that you do become pregnant, you notify study staff immediately and 
immediately stop taking the provided medicine.

WILL I RECEIVE ANY COMPENSATION FOR TAKING PART IN THIS STUDY?  
 
If you complete all of the visits and all of the procedures as described for the entire 
study, you will receive up to $400 in total compensation. $300 will be paid in installments 
and prorated as follows: you will not receive compensation for visit 1 (the screening visit). 
You will receive $60 following completion of baseline testing (visits 2 and 3).  After 
successfully completing 8 weeks of the intervention you will receive $60; after completing 
12 weeks you will receive $60.  You will receive $60 for completion of visit 28 and $60 for 
completion of visit 29. If you are at least 95% compliant both in terms of visit attendance 
and pill ingestion, you will receive an additional $100.   
 
Should your participation in the study end early, you will still receive feedback pertaining 
to your health.   
 
WHAT HAPPENS IF I AM INJURED BECAUSE OF THE RESEARCH?  
 
We will arrange to get you medical care if you have an injury that is caused by this 
research.  
 
CSU will pay for medical expenses for the treatment of a personal injury that is a direct 
result of the administration of the study drug (CSU will be reimbursed by AstraZeneca). 
CSU will not provide compensation for lost wages or for any other damages, expenses 
or losses, or for medical expenses that have been covered by medical insurance.  
 
Should you sustain an injury that is not the direct result of the study drug, you or your 
insurance company may have to pay for the required care. The Colorado Governmental 
Immunity Act determines and may limit Colorado State University, University of 
Colorado Denver and University of Colorado Hospital’s legal responsibility if an injury 
happens because of this study. Claims against the University must be filed with 
Colorado State University within 180 days of the injury. 
 
WHAT IF I HAVE QUESTIONS?
