Brief summary:
The purpose of this study is to assess whether water-soluble cinnamon extract plus aggressive lifestyle intervention is effective in lowering blood glucose in pre-diabetic patients when compared to aggressive lifestyle therapy plus placebo.

Detailed description:
We are studying whether water-soluble cinnamon extract (Cinnulin PF) plus standard of care aggressive lifestyle therapy is effective in lowering blood glucose when compared to placebo plus standard of care aggressive life style therapy. Eligible subjects will be recruited from any form and any stage of "standard" lifestyle intervention for pre-diabetes at an individual base. "Standard" lifestyle intervention for pre-diabetes could include Group Lifestyle Balance (GLB), nutrition classes, Better Body/Better Life, or anything an investigator certifies as standard practice at that base. Subjects will take either 1 gram (2-500 milligram (mg) capsules) of water-soluble cinnamon extract (Cinnulin PF) or 2 placebo pills (gelatin capsule filled with wheat bran) once a day for 1 year plus 1 additional year of follow-up. This is a randomized, double-blind, multicenter, placebo-controlled study which will enroll subjects at the Mike O'Callaghan Federal Medical Center (MOFMC), Wilford Hall Ambulatory Surgical Center (WHASC), David Grant Medical Center (DGMC), Eglin Air Force Base (Eglin), and Offutt Air Force Base (Offutt). All subjects will be MOFMC, WHASC, DGMC, Eglin, and Offutt DoD beneficiaries. Informed Consent and HIPAA Authorization will be obtained. After randomization, subjects will receive either 1 gram (2-500 mg capsules) of water-soluble cinnamon extract or placebo from the pharmacy--thus investigators and subjects will be blinded as to if they are taking Cinnulin PF or 2 placebo pills. Subjects will be permitted to have usual medical care for other co-morbid, preventive, and acute conditions. Analysis will be performed using intention-to-treat principles for missing data (the carry-forward method to impute missing data will be used). Subjects will bring in any remaining water-soluble cinnamon extract or placebo to determine adherence rates to the study protocol.

Arms: arm 1: Will take (by mouth) 2 gelatin capsules that contains 1 gram (2-500 mg capsules) water-soluble cinnamon extract (Cinnulin PF) once a day for 1 year plus 1 year of follow-up plus standard of care aggressive lifestyle therapy. arm 2: Will take (by mouth) 2 placebo capsules (gelatin capsule filled with wheat bran) once a day for 1 year plus 1 year of follow-up plus standard of care aggressive lifestyle therapy.
Interventions: intervention 1: water-soluble cinnamon extract (Cinnulin PF)
Intervention descriptions: intervention 1: Will take (by mouth) 1 gelatin capsule that contains 1 gram water-soluble cinnamon extract (Cinnulin PF) once a day for 12 months plus standard of care aggressive lifestyle therapy

3.  Research Plan: 
3.1. Purpose: 
The purpose of this study is to assess whether water-soluble cinnamon extract plus aggressive lifestyle intervention is 
effective in lowering blood glucose in pre-diabetic patients when compared to aggressive lifestyle therapy plus placebo.
3.2. Hypotheses, Research Questions or Objectives: 
Does water-soluble cinnamon extract have an effect on fasting glucose, Hemoglobin A1c, lipid panel, and waist 
circumference in pre-diabetic patients who are already undergoing aggressive lifestyle therapy?
This study has the following goals:
1. Determine the length of time to diagnosis of diabetes using any of the ADA criteria.
2. Determine: 
a)
Fasting glucose
b)
Hemoglobin A1C
c)
LDL cholesterol, and
d)
Waist circumference (in inches)
3.3. Significance:  
Lowering hemoglobin A1c is correlated with reduced complications in Type 2 diabetes (e.g., retinopathy, nephropathy, 
neuropathy, vascular disease, and death).  Water-soluble cinnamon extract is inexpensive, readily available, generally 
recognized as safe, and a non-pharmacological approach to management.  According to the 2010 American Diabetes 
Association Guidelines, lifestyle intervention is the most effective way for diabetes.  Historically, it has been difficult for 
subjects to adhere to lifestyle education programs and sustain meaningful weight loss without using significant resources, 
as in the Diabetes Prevention Study (NEJM, 2002).
3.4. Military Relevance: 
Diabetes not only has a high morbidity and mortality amongst military beneficiaries but also is a drain on the military’s 
medical budget.  If cinnamon is found effective, it may result in long-term health care cost savings and better outcomes for 
our patient population.  Diabetes research in the Air Force is needed to not only support its peacetime healthcare mission, 
but reduce Air Force health care costs, thereby freeing up funds to support other missions of the AFMS.

3.5. Background and Review of Literature: 
As the worldwide incidence and prevalence of diabetes increases, the search for dietary adjuncts to treat this life-altering 
disease becomes far ranging.  Cinnamon is purported to be a natural insulin sensitizer with adverse events of peri-oral 
dermatitis and stomatitis reported uncommonly with high intake.2  There is one report of a severe exacerbation of rosacea 
after initiation of cinnamon for treatment of diabetes.3 It is designated by the U.S. Food and Drug Administration as 
“Generally Recognized as Safe”.  This product was submitted to the FDA as an Investigational New Drug. 
Both in vitro and in vivo animal studies have shown that cinnamon is an insulin sensitizer.4,5 Kim et al. showed that 
intestinal glucosidase activity in rats was increased by cinnamon.5 Polyphenols within cinnamon have been identified as 
upregulators of mouse adipocyte insulin receptors.6 Peng and colleagues found that polyphenols from cinnamon inhibit 
the formation of advanced glycation end-products in bovine serum albumin.7 Cinnamon extract (CE), high in type A 
polyphenols, prevents fructose feeding-induced decreases in insulin sensitivity. CE improves the postprandial 
overproduction of intestinal apoB48-containing lipoproteins by ameliorating intestinal insulin resistance and may be 
beneficial in the control of lipid metabolism.8
Cinnamon may improve glycemic control and insulin sensitivity.9 To date, seven randomized trials studying cinnamon in 
humans with Type 2 diabetes have been published with conflicting results.10-15  The results of these studies are mixed.  
Two of these studies showed a possible effect of cinnamon on fasting serum glucose, but they did not examine 
hemoglobin A1c levels.10,11 One study showed no effect on plasma glucose.12 Two studies--one each in patients with Type 
1 and Type 2 diabetes--showed no effect of cinnamon on Hemoglobin A1c.13,14 Cinnulin PF® supplementation reduced 
fasting blood glucose and systolic blood pressure, and increased lean body mass in a randomized trial in men and women 
with the metabolic syndrome.16 A meta-analysis of these studies in divergent populations measuring different parameters 
showed no effect of cinnamon on hemoglobin A1c, glucose or lipids.17 Subsequently, a RCT of 109 patients compared 
add-on treatment with 1 gram daily of cinnamon over a 3 month period to usual care in a population of poorly controlled 
Type 2 diabetics, it found that cinnamon lowered hemoglobin A1c 0.83%--similar to some prescription drugs.15 This led to 
a call for more comparative effectiveness research of cinnamon versus prescription medications.18
There have been no trials assessing if water-soluble cinnamon extract is effective at lowering blood glucose.  Guidelines 
recommend that new diabetics receive treatment with Metformin to help with insulin sensitization, lower blood glucose, 
and assist with weight loss.  Water-soluble cinnamon extract appears to have many of the same mechanisms of 
Metformin. 
Research has shown that pre-diabetics convert to diabetes at an average of 7% a year and other research performed on 
prevention have been multi-year trials.  In order to obtain adequate power for this study, subjects will take water-soluble 
cinnamon extract or placebo for 1 year.

3.6. Research Design and Methods: 
We will recruit male and female subjects between the ages of 18-65 years old with a diagnosis of pre-diabetes.  Eligible 
subjects will be recruited from any form and any stage of “standard” lifestyle intervention for pre-diabetes at an individual 
base. “Standard” lifestyle intervention for pre-diabetes could include Group Lifestyle Balance (GLB), nutrition classes, 
Better Body/Better Life, or anything an investigator certifies as standard practice at that base.
To capture potentially eligible subjects, we will use one or more of the following recruitment strategies. The instructors of 
these “standard” lifestyle interventions will:
1.
Utilize the Marquees on base. The marquee will state “Pre-Diabetic, Contact (insert contact) for Cinnamon Trial, 
(insert phone number)
2.
Mail a recruitment letter to all participants. 
3.
Announce at the beginning of class that we have a research study that they may potentially be interested in and 
ask permission to forward their contact information along to the research staff.

VISIT WINDOWS: Visits have a window of plus or minus 10 days. Subjects are encouraged to come in as close to the 90 day 
mark as possible since they are only given a 90 day supply of IP.  Postponement of any follow up visits (after subject 
stopped taking study medication) is authorized for up to 6 weeks in case of a temporary condition that would affect 
glucose tolerance (i.e. moderate to severe illness to be determined by study PI or Site AI).  A note to file documenting 
such shall be placed in the subject’s study folder and documented in the data collection form.
ADHERENCE TO STUDY ASSIGNMENTS: Adherence to study medication will be assessed via review of the “Study 
Medication Diary”. Compliance will be recorded both in paper format and in the electronic data collection tool. If a subject 
misplaces their Study Medication Diary, they will be asked to reproduce it from memory to the best of their ability. 
Subjects will be instructed to bring back all of the bottles regardless of whether there are empty or contain missed doses.
If at any time a subject stops taking their water-soluble cinnamon extract or placebo, they will remain in the study, will be 
instructed to return any pill bottles, and will continue follow-up in the study.  Regardless of the amount of missed doses, all 
subjects will remain in the study and continue with all the study related visits.  Research staff will document the missed 
doses and subjects will continue in the research study.  If the subject decides to re-start their water-soluble cinnamon 
extract or placebo, they will resume the study at their last documented visit (i.e. subject stops taking water-soluble 
cinnamon extract or placebo at Visit 4 and decides 1 year later that they wish to resume the study, their next visit would 
be Visit 5).
If a subject misplaces or loses their study medication, they will be instructed to return to the pharmacy and will be given a 
new bottle of their assigned study medication.  Since the pharmacy is not blinded, they will be able to give the medication 
that the subject was assigned.

If a subject forgets to bring their study medication in for their visit, they will be instructed to bring it in at their earliest 
convenience.
DIRECTIONS FOR TAKING MEASUREMENTS:  A measuring tape to measure subjects’ waist circumference will be 
provided to the study team.  A designated study staff member will obtain the waist circumference measurements to 
ensure consistent measurements throughout the study.
Directions for taking waist circumference measurement:  Have subject take a deep breath, blow out, and hold with 
abdominals tightened.  Tell subjects not to suck in their stomach.  Take the measurement around the largest part of their 
waist.  Waist circumference should be recorded to the nearest ½ inch (for example 40.5”).
Directions for weighing subjects:  Have subject remove his/her shoes and empty pockets of any items prior to stepping on 
the scale.  Weight should be recorded to the nearest ½ pound (for example 150.5#).
Directions for taking height:  Have subjects remove their shoes before taking their height.  Height should be recorded to 
the nearest 1/2 inch (for example 60.5”).
Directions for taking blood pressure: Have subjects sit for 5 minutes before taking blood pressure.
WITHDRAWAL PROCEDURES: If at any time during the study, the subject decides to withdraw consent they will be 
referred back to their Primary Care Manager (PCM).  If a subject is found to be diabetic during the course of the study, 
they will be withdrawn and referred to their PCM to initiate standard of care treatment. Standard of care typically follows 
the DoD Clinical Practice guidelines for self-monitoring of blood glucose. As part of this, the Air Force provides 
glucometers and supplies at no charge.
ADVERSE EVENTS (AEs) AND DEVIATIONS: The Associate Investigator (AI) at each site is responsible for reviewing, 
categorizing, and properly reporting to the main PI AEs that occur with their subjects. The “Algorithm for Determining 
Whether an Adverse Event is an Unanticipated Problem” is attached to assist in guiding the research staff on the 
categorizing of Adverse Events, Protocol Deviations, and Serious Adverse Events.
Serious Adverse Events (SAEs) and Serious Protocol Deviations  are defined as unexpected events that increase the 
risk to subjects and that were possibly, probably, or definitely related to the research.  These must be reported to the 
WHASC IRB within 5 days.  Each site is responsible for reporting these to Col Crawford, the local Site Principal 
Investigator, and Jill Clark immediately via the “Possible Internal (Local) Reportable Unanticipated Problem Involving Risk 
to Subjects or Others (UPIRSO)” form.
If a subject experiences an allergic reaction during the study, they will be instructed to stop taking the study medication 
and seek urgent medical treatment.
Adverse Events (AEs) and Protocol Deviations that do not increase the risks to subjects like those listed in the “risks” 
section of this protocol are to be reported to Col Crawford, the local Site Associate Investigator and Jill Clark as they occur 
or no later than the 1st workday of every month via the “WHASC Tracking Log for Adverse Events (AEs)/Protocol 
Deviations Not Requiring Immediate Reporting.  This is done to ensure ongoing monitoring and identification of trends that 
may arise.
Guidance for completing the SAE/AE forms:
•
When completing the forms, please ensure that you include as much information as possible, to include:
o
Date the patient reported the event
o
Date the event occurred or the date that you discovered the event happened/began
o
A detailed description of the event including any tests/procedures that were performed with dates
o
Any directions given to the patient including the date
o
Description of the resolution with the date
•
When answering the questions:
o
“Was the event unexpected?": Select YES only if the event was NOT already listed in the risks/benefits 
section of the Protocol or part of an existing disease process.
o
"Did the event cause increased risk to participants or others": Select YES only if the adverse event was 
serious, which includes events that are life threatening or results in: death, inpatient hospitalization, 
prolongation of existing hospitalization, persistent or significant disability/incapacity, congenital 
anomaly/birth defect, or may jeopardize the subject's health and may require medical or surgical 
intervention to prevent one of the outcomes above. If the event is not serious but there is a trend that 
would warrant a change in the protocol/ICD (i.e. several patients experienced a rash), then you would 
also select YES.
o
"Was the event possibly, probably, or definitely related to the research procedures?": Select YES if it is 
due to the research itself not underlying disease or disorder. If there isn't adequate information available 
to assess this, the answer would be NO.


Revised by PR 2019

o
"Should the consent form/process be revised": Select YES only if it warrants a revision to the research 
process or risks/benefits (this should be discussed with Col Crawford if you are selecting YES).
o
"Summary of events in the opinion of the local investigator": please have your Local Site Associate 
Investigator comment such as "no increased risks to subjects participating in the study" (just an example). 
Then have your Site Associate Investigator sign, print their name, and date. Then return the scanned 
copy to Col Crawford and Jill Clark. They will then get the Research Monitor to complete Section 6, and 
return a copy to be filed in the subjects file.
PREGNANCY: Subjects must agree to take precautions to prevent pregnancy during the course of this study due to the 
possible effect water soluble cinnamon extract may cause an unborn child.  The only completely reliable methods of birth 
control are total abstinence or surgical removal of the uterus.  Other methods, such as the use of condoms, a diaphragm or 
cervical cap, birth control pills, IUD, or sperm killing products are not totally effective in preventing pregnancy.  In addition, 
women who are breastfeeding may not participate in this study.
If a subject unintentionally becomes pregnant, they will be instructed to cease water-soluble cinnamon extract or placebo, 
return any pill bottles and will continue follow-up in the study.  They will be encouraged to resume taking water-soluble 
cinnamon extract or placebo and blood work (if they choose) 6 months after delivery of their child.  If the subject decides to 
re-start their water-soluble cinnamon extract or placebo, they will resume the study at their last documented visit (i.e. 
subject stops taking water-soluble cinnamon extract or placebo at Visit 4 and decides 1 year later that they wish to 
resume the study, their next visit would be Visit 6).
SUBJECTS ENROLLED NO LONGER PRE-DM:  If a subject becomes no longer pre-diabetic while enrolled in the study, 
they will remain in the study.
SUBJECTS ENROLLED BECOME TYPE II DIABETIC:  If a subject becomes Type II diabetic while enrolled in the study, 
they will be removed from the study. 
SUBJECTS COMPLETING THE STUDY:  When subjects have completed the study, the Pharmacy will de-identify the 
information and send to the Investigator for analysis.  Each Associate Investigator will send the de-identified data to the 
Principal Investigator via an encrypted email for analysis.
HYPOGLYCEMIC EPISODES: If the subject experiences a hypoglycemic (low blood sugar) episode, e.g., for example 
heart palpitations (abnormal heart beats either fast or slow), tremors (involuntary muscle movement), hunger, sweating, they 
should be instructed to eat 15-20 grams of sugar (e.g., glucose (sugar) tablets, glass of juice or other snack containing sugar) 
then eat some carbohydrates (e.g., a small meal or cracker with peanut butter).
BLOOD TEST OUTSIDE OF NORMAL REFERENCE RANGE: Research Coordinators at each site will print the blood 
test results and place in the subject’s folder.  If any of these results are outside of the normal reference range noted by 
their lab, they will place a telephone consult for the subject’s Primary Care Manager (PCM).
DISPOSAL OF STUDY RELATED PILLS: Subjects will return any remaining study-related pills directly to the Research 
Coordinator or Principal Investigator. The Research Coordinator or Principal Investigator will be responsible for disposing 
of the study-related pills. The preferred method of disposal is to have the Pharmacy dispose of them. If the Pharmacy is 
unable to dispose of them, they will provide directions on safe disposal for the Research Coordinator or Principal 
Investigator to follow.
OTHER ITEMS: If at any time, a site needs more study medication, they should contact the main site at the Nellis AFB 
and request.  Integrity Nutraceuticals should not be contacted directly. Prior to ordering any standard of care labs, study 
staff will verify in AHLTA that the subject did not have that lab test within the previous timeframes documented in the study 
visits above.  In addition, CHCS has alerts built in that will alert the person entering the lab test that there is a pending 
order.
Subjects will take their water-soluble cinnamon extract or placebo daily and will be permitted to have the usual medical 
care for other co-morbid and acute conditions if applicable.  Analysis described above using intention-to-treat principles 
for any missing data will be used (we will use the carry-forward method to impute missing data).
The placebo will be a gelatin capsule filled with wheat bran, which does not increase the risks to subjects.
Each site’s Laboratory will be responsible for analyzing blood samples obtained at their site for this study.  Samples will 
be labeled as they would for standard laboratory draws.  All Laboratories follow Clinical Laboratory Improvement 
Amendments (CLIA) procedures when processing laboratory specimens mentioned in this research project.
This study involves the use of an investigational product (IP) called Cinnulin PF (water-soluble cinnamon extract).  This means 
that the product has not been approved by the Food & Drug Administration (FDA) for preventing or delaying the onset of 


Revised by PR 2019

diabetes.  However, the FDA has not objected to its use to study its effectiveness.  Water-soluble cinnamon extract (Cinnulin 
PF) is being used to assess its effects on insulin in pre-diabetic subjects.  It is being given in a dose that does not 
increase the risk to the research subjects.  There are no known risks associated with water-soluble cinnamon as it is a 
compound granted GRAS (Generally Recognized As Safe) status by the United States Food and Drug Administration 
(more information can be found at http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=582.20).
3.6.1. Interventions, Observations, or Data Sought: 
We will assess effect of 1 gram (2-500 mg capsules) of water-soluble cinnamon extract taken once a day for 1 year plus 1 
year of follow-up and obtain fasting glucose, Hemoglobin A1c, lipid panel, height, weight, and waist circumference (in 
inches). Additionally, to assess safety of long term cinnamon use, electrocardiograms will be performed to evaluate for QT 
prolongation.
3.6.2. Data Collection and Processing: 
Subjects will be randomized by the pharmacy. Pharmacist acting as Associate Investigators will be unblinded to study 
medication assignments. At the conclusion of the study, Pharmacists will provide the blinded information to the Principal 
Investigator for analysis. Both subjects and Investigators will be blinded to the study assignments. Data will be collected 
and recorded in a spreadsheet. At the conclusion of the study, all personally identifying information will be removed prior 
to analysis based on AFI 33-332, “The Air Force Privacy and Civil Liberties Program” and the “National Institute of 
Standards and Technology Special Publication (NIST SP 800-88) for the approved methods to destroy PII”. Each subject 
will be asked to place their de-identified study-related data into the “Nellis Diabetes Research Data Repository 
(FWH20110136H)” for future research. If the subject does not give their authorization, then all de-identified study-related 
data will be destroyed no later than at the closure of the study.

Eligible subjects will be recruited from any form and any stage of “standard” lifestyle intervention for pre-diabetes at an 
individual base. “Standard” lifestyle intervention for pre-diabetes could include Group Lifestyle Balance (GLB), nutrition 
classes, Better Body/Better Life, or anything an investigator certifies as standard practice at that base.  No special 
populations (i.e. children, prisoners, pregnant women, mentally disabled persons, or economically or educationally 
disadvantaged persons) will be eligible for this study. There are currently 2,950 diabetic patients empaneled for care at 
Nellis AFB. Several thousand more are pre-diabetic--many of these will likely attain the diagnosis of diabetes within 36 
months.

3.6.8. Instrumentation: N/A
4.0.  Human Subject Protection:
4.1. Recruitment: 
All potentially eligible patients will be offered an opportunity to participate. Primary Care Managers (PCMs) who are not 
part of the research team will be informed about the study and provided information on the inclusion/exclusion criteria. 
PCM referrals and posted advertisements will be utilized for recruiting subjects to the study. Some patients may be 
patients of the PI or AI, however, they will have the study staff recruit their patients to prevent any misconception of 
coercion or undue influence. If a potential subject is identified by the treating PCM and is interested in obtaining more 
information about the study, the patient will either be provided a contact number to the Research Staff, the Research Staff 
will be given the potential subject’s contact information by the PCM with the patient’s oral or written authorization, or the 
PCM will come and get the Research Staff to speak with the patient directly. Lifestyle Intervention instructors will also 
provide referrals with the patient’s oral or written authorization. We will also utilize the Marquees on base (the marquee 
will state: Pre-Diabetic, Contact (insert contact) for Cinnamon Trial, (insert phone number) for recruitment. 
We are requesting a HIPAA Waiver so we are able to review the AHLTA schedule for potential participants. The data 
collected will only be used for recruiting and will be destroyed after contact with individual patients has been made.  The 
clinical research coordinator will review the schedules of clinicians to find eligible patients within their schedule. The 
coordinator will proceed to inform the clinician of any possibly eligible subjects for the study.  Each participating clinic will 
mail their pre-diabetic patients a letter informing them of the Cinnamon trial, and giving them the opportunity to participate 
or opt out. The mailing of these letters will be tasked to a study team member at the study site. We are also requesting to 
obtain a list from the Disease Management nurse on behalf of Family Medicine and Family Health Clinics. This list will be 
used to mail out letters to potential participants to increase recruitment
4.2. Consent Processes: 
Informed consent and HIPAA authorization will be sought in advance from each prospective subject.  Informed consent 
will be appropriately documented.  [32 CFR 219.117] After discussion with the Investigator, the subject will be given the 
opportunity to consent.  The Investigator will provide a written copy of the consent form and allow the subject to read it, 
review it with the subjects, and answer questions.  The subject may decline to consent, and no pressure will be applied.  If 
the subject consents, the proper signatures will be obtained, and a copy will be given to the subject.
4.3 Participation Compensation: Subjects will not be paid for participation in this study.
4.4. Assent Process: N/A
4.5. Benefits: 
The benefits to the subjects may include lower hemoglobin A1c levels and improvement of long-term health by decreasing 
the risk of developing diabetes.
4.6. Risks:

[X]
Paper data, including completed consent forms
The research consents and HIPAA Authorization 
Documents will be stored in a locked cabinet in a locked 
room with restricted access.
[X]
Electronic data
Medical records will be annotated to reflect the subject’s 
participation in a research study. All coded, de-identified 
research data will be electronically stored separately from 
the Master Key of identifiable patient demographics and 
PHI/PII.
[X]
Long-term storage (following completion of the 
study and inactivation of IRB approval)
The research data will be coded and any links to 
identifiable data will be destroyed (an approved shredding 
bin) as soon as possible or no later than at the closure of 
the study, with the exception of those study subjects that 
consent to place their de-identified research data into the 
“Nellis Diabetes Research Data Repository 
(FWH20110136H) for future research. The anonymized 
research data will not be utilized for further research 
activity beyond the protocol stipulations without additional 
IRB approval.  All de-identified research data will be 
maintained for 3 years following study closure.
4.9. Safeguards for Protecting Subjects: 
The Principal Investigator will be responsible for the protocol safety monitoring.  The PI will make study documents (e.g., 
consent forms, data pulls) and pertinent hospital or clinical records readily available for inspection by the local IRB and 
over sight staff for confirmation of the study data.  Integrity Nutraceuticals, Inc. will not have access to subjects’ medical 
records.
4.9.1. Minimizing Risks: 
Risks in this study are minimal and only relate to a blood draw and water-soluble cinnamon extract.  Subjects will have 
access to study personnel should they have any issues.  If there are any issues, they will be immediately reported to one 
of the Investigators and an applicable medical evaluation will be initiated.  There is also a risk of inadvertent breach of 
confidentiality.
  
4.9.2. Vulnerable Populations: No vulnerable populations will be recruited.
4.9.3. Clinical Care: 
If a subject experiences any injury, adverse event, or unexpected clinical finding, a PI, AI, or Primary Care Manager will 
be available to assess the subject and initiate proper clinical care.
4.9.4. Injury Compensation: Subjects will not be compensated for injuries.
4.9.5. Data Safety Monitoring: 
The trial will be conducted in compliance with this protocol, International Conference on Harmonization (ICH) Guidelines 
for Good Clinical Practice (GCP), and any applicable national and international regulatory requirements.  The Principal 
and Associate Investigators will be monitoring all aspects of the study in accordance with the appropriate regulations and 
will have regular meetings with periodic quality control of data documentation and collection.  The objectives of the 
monitoring meetings will be:
1) To verify the prompt reporting of all data points, including reporting SAE's and checking availability of signed informed 
consent,
2) To compare individual subject records, data pulls and/or the study source documents/case report forms (supporting 
data, laboratory specimen records and medical records to include physician progress notes, nurses’ notes, subjects’ 
hospital charts),
3) To ensure protection of study subjects, compliance with the protocol, and accuracy and completeness of records.
David Moss, DO, Capt (Primary) and Matthew Hawks, MD, Capt (alternate) will be the research monitors assigned to this 
study.
The PI will make study documents (e.g., consent forms, data pulls) and pertinent hospital or clinical records readily 
available for inspection by the local IRB and over sight staff for confirmation of the study data.
5.0. Alternatives: The alternative is not to participate in this study.
6.0. Data Analysis: 
6.1. Outcome Measures: 


Revised by PR 2019
15
We will be assessing the effect of 1 gram (2-500 mg capsules) of water-soluble cinnamon extract (Cinnulin PF) on pre-
diabetic subjects and obtaining hemoglobin A1c, lipid panel, height, weight, and waist circumference measurements (in 
inches).
6.2. Sample size estimation/power analysis: 
A priori power for H01 was assessed using G*Power Version 3.0.10 1. The results indicate 214 subjects per group with 8 
repeated measures for a total sample size of 3424 will achieve a power of approximately 0.99 to detect a small effect size 
of 0.10 at α = 0.0004.
A priori power for H02 was assessed using the method described by Glantz2 to calculate sample size for a two-sample 
log-rank test to detect differences in the time to event.  Based on this design, it will require a minimum of 214 subjects per 
group to detect a difference between a 17.5% conversion in the Placebo + lifestyle and an 11.5% conversion in the 
Cinnulin + lifestyle group at α = 0.05 (one-sided) and power of 0.80. 
We are enrolling 557 subjects total, for an expected 428 completing the study.  We estimate 129 subjects’ will either 
withdraw consent or drop out of the study.
6.3. Statistical Analysis: Statistical Analysis Plan

Technical Objective: The objective of this study is to compare Cinnulin PF, a cinnamon extract, in combination with a 
lifestyle management program, to a placebo and life style management program, and to evaluate the prevention or delay 
the development of Type 2 diabetes in persons with pre-diabetes.  
Sample: Subjects will be a random sample of males and females between the ages of 18-65 years with a diagnosis of 
pre-diabetes seen in certain Air Force medical treatment facilities.  The subjects are presumed to be randomly selected 
from the population of patients obtaining similar care at all Air Force medical treatment facilities. 
 Hypothesis:
H01 – No difference in means of continuous dependent variables between and among treatment groups
H02 – Cinnulin + Life Style and Placebo + Life Style groups have identical survival functions for the time to reach the Type 
2 diabetes conversion event.
Study Design: The experimental design of this study is a mixed effects, randomized complete block design with repeated 
measures.  Subject is a random effect as the subjects are a sample randomly selected and randomly assigned to a 
treatment group.  Fixed effects are treatment group and time of repeated measure as these effects cannot be generalized 
to other treatments and times.  Subjects will be randomly assigned to each treatment group.      
Factors:
1.
Subject
2.
Treatment: Cinnulin PF + Life Style Management versus Placebo + Lifestyle Management
3.
Repeated Measurements: Laboratory and physical measurements obtained from each subject at fixed intervals for the 
duration of the study (N=8).

DESCRIPTION/PURPOSE OF RESEARCH (Why is this study being done?):  
You are being asked to consider participation in this research study. The purpose of this study is to see whether 
water-soluble cinnamon extract is effective in lowering blood glucose in patients undergoing aggressive lifestyle 
therapy. This study will have two groups of patients, Group 1 will take by mouth, 2 gelatin capsules that contains 1 
gram of water-soluble cinnamon extract (Cinnulin PF) once a day for 1 year and then be followed for an additional 1 
year plus standard of care aggressive lifestyle therapy. Group 2 will take by mouth, 2 placebo pills (gelatin capsule 
filled with wheat bran) once a day for 1 year, and then be followed for an additional 1 year plus standard of care 
aggressive lifestyle therapy. Investigators will then compare both groups to see if the use of the water-soluble 
cinnamon effect on fasting plasma (blood) glucose, hemoglobin A1c, lipid panel, and waist circumference. 
 
You are being asked to consider participation in this study because you have prediabetes. People with blood glucose 
(sugar) levels that are higher than normal but not yet in the diabetic range have "prediabetes”. People with 
prediabetes usually have no symptoms. You may have had prediabetes for several years without noticing 
anything. It is important to identify people with prediabetes because they have a higher risk of developing 
diabetes in the future. When you have high blood sugar over a long period of time your blood vessels in your 
heart, kidney, and eyes can get damaged. 
 
Aggressive lifestyle therapy is defined as participation in any standard lifestyle intervention that your doctor refers 
you to as part of your routine care.  
 
This study will enroll approximately 557 subjects at Nellis AFB. Your participation in this study will last approximately 
24 months. 
 
PHASE III STUDY:  
This study involves the use of an investigational product called Cinnulin PF (water-soluble cinnamon extract). This 
means that the product has not been approved by the Food & Drug Administration (FDA) for treating or preventing 
diabetes.  This study will help find out what effects, good and/or bad, of water-soluble cinnamon extract in lowering 
blood glucose. Cinnamon is supposed to be a natural insulin sensitizer, which means it helps the body return your 
blood sugar to normal. Insulin helps to control the amount of glucose (blood sugar) that is dissolved in the blood. 
Insulin prevents the blood sugar level from rising too high. The safety of this product in humans has been tested in 
prior research studies; however, some side effects may not yet be known.   
 
PROCEDURES:  
If you decide to take part in this research study, you will be asked to sign this consent form. During your participation 
in this study, you will be asked to make approximately 9 outpatient visits with the Principal Investigator (PI), an

participant, you will undergo the following procedures:  
 
Screening Visit:  Exams, tests, and/or procedures may be done after you sign this consent to participate. This 
screening is done to find out if you can continue in the study (screening procedures). We may be able to use the 
results of exams, tests, and/or procedures you completed before enrolling in this study. You will be told which results 
we will obtain and which procedures will not have to be repeated. Any procedure described below as “standard care” 
would be done even if you do not take part in this research study.

(like flipping a coin) to 1 of 2 study groups. One group will have their standard of care diabetes treatment of 
aggressive lifestyle therapy plus placebo. The second group will have water-soluble cinnamon extract (Cinnulin PF) 
plus aggressive lifestyle therapy to see how it affects fasting glucose, hemoglobin A1c, lipid panel and waist 
circumference. You will have a one in 2 chance of being in the placebo group. A placebo is an inactive, harmless 
substance that looks like the water soluble cinnamon extract (Cinnulin PF). Neither you nor the researchers will know 
whether you are receiving standard treatment with placebo or water-soluble cinnamon extract. In the event of an 
emergency, there is a way for the researcher to find out which you are receiving. 
 
RISKS OR DISCOMFORTS: Risks from the specific research procedures (drug(s), interventions, or procedures) 
There are risks to taking part in this research study. One risk is that you may have side effects while on the study. Side 
effects can range from mild to serious. Serious side effects are those that may require hospitalization, are life 
threatening or fatal (could cause death).  The frequency that people experience a certain side effect can range from 
many (likely), few (less likely) or only one or two (rarely).  Side effects from this study will usually go away soon after 
you stop taking the water-soluble cinnamon extract (Cinnulin PF). The side effects related to the blood draw will 
usually go away soon after the blood draw has been completed. In some cases, side effects can be long lasting or may 
never go away. Everyone taking part in the study will be watched carefully for any side effects. However, the study 
doctors don’t know all the side effects that may happen. Be sure to tell your study doctor immediately, about any side 
effect that you have while taking part in the study. 
 
The following section will describe the risks related to each drug, intervention, or procedure that is part of this 
research study. You should talk to your study doctor about any side effects or other problems that you have while 
taking part in the study. Risks and side effects related to the water-soluble cinnamon extract (Cinnulin PF) include 
those which are: 
 
Less likely and not serious 
• Hypoglycemia (low blood sugar): 
o Heart palpitations (abnormal heart beats either fast or slow) 
o Tremors (involuntary muscle movement) 
o Hunger 
o Sweating 
*If you experience any of these symptoms, you should eat 15-20 grams of sugar (for example glucose (sugar) tablets, 
glass of juice or other snack containing sugar), then eat some carbohydrates (for example a small meal or cracker 
with peanut butter). 
 
Less Likely and serious 
• Cinnamon and Wheat Bran: There may be a risk that you have an allergy to cinnamon or wheat bran that you 
are not currently aware of. The signs and symptoms of an allergic reaction include: 
o Shortness of breath 
o Hives (itchy rash) 
o Runny nose 
o Watery eyes

measurements and surgical procedures and post-surgery outcomes. This data is considered both identifying and 
non-identifying information and may be traced back to you as a donor when added to a database. The Principle 
Investigator and Database Repository Manager will take every precaution possible to safeguard your information 
to eliminate the possibility of any breach of confidentiality. This is explained below in the section, 
“Confidentiality”. The Database Repository Manager, Col Paul Crawford, is responsible for all PHI and PII data 
stored in the repository. All recipient investigators requesting data from the repository must have approval from 
the Database Repository Manager and must have a research study approved through a DoD Institutional Review 
Board (IRB) and the WHASC IRB. Only de-identified data (no personal identifiers or information) will be released to 
recipient investigators, so specific information can’t be traced back to the donor of the data. Recipient 
investigators may only receive limited data sets of de-identified information necessary to conduct their research. 
Generally, you will not be provided with the results of these research studies using your de-identified data from 
the repository. Any results would be of unclear value and unknown clinical meaning, since your de-identified data 
will be combined with other de-identified data from numerous patients used for the study. 
 
You may request that your PHI and PII data be withdrawn from the database repository at any time, if you decide 
you no longer want to participate. This request may be accomplished by calling the Database Repository Manager 
at Col Paul Crawford or mailing your request to the following address: Col Paul Crawford, MD, c/o Department of 
Medical Education, 4700 Las Vegas Blvd North, Nellis AFB, NV 89191. 
 
_______NO: I do not authorize the storage of my PHI and PII data for future use in research studies. 
 
_______YES:  I authorize the storage of my PHI and PII data for future use in research studies.
