Study Product, Dose, 
Route, Regimen 
Intranasal Oxytocin 24 IU self-administered q.i.d. (3 puffs each nostril 4x/day) 
for 8 weeks 
Statistical Methodology 
Generalized linear mixed effects model will be used to evaluate the effect of 
oxytocin on the change of each continuous measure.  The effect of oxytocin will 
be assessed by whether the time by oxytocin interaction is significantly different 
from 0 with a 2-sided p-value<0.05

1.4. Preliminary Data 
Recent work in mice showed that short-term systemic oxytocin delivery restores muscle regeneration in old mice 
by improving aged muscle stem cell function 4. This work also demonstrated that oxytocin acts directly on muscle 
stem cells (in vitro and in vivo) and that the pro-myogenic effects of oxytocin are mediated by MAPK/ERK 
signaling. The effect of oxytocin on skeletal muscle in humans has not yet been studied to our knowledge.    
1.5. Investigational Agent 
Intranasal oxytocin was marketed in the U.S. beginning in 1957 and used in the 1960’s in the postpartum period 
for milk let-down. It was taken off the market in 1995 in the U.S., but it is still available in Europe. There are 
several clinical trials now listed on clinicaltrials.gov studying the use of intranasal oxytocin for autism, dementia, 
and other psychological and developmental conditions.   
1.6. Dose Rationale and Risk/Benefits 
With assistance from the College of Pharmacy of University of Texas at Austin, we performed a literature review 
of the safety and side effect profile of intranasal oxytocin. To summarize, the studies reviewed that studied 
lactation did not have any significant adverse events or complications related to the use of intranasal oxytocin. 
The side effects noted with intranasal oxytocin were rare instances of headache, nausea, and allergic dermatitis 
(between 1/1000 and 1/10,000 occurrences, and occasional abnormal uterine contractions (between 1/100 and 
1/1000 occurrences). In our study we expect fewer uterine contraction occurrences since none of the women 
enrolled will be postpartum and all will be post-menopausal. In studies that examined the use of intranasal 
oxytocin for conditions other than lactation, a recent article on this subject was also recently published 22. This 
article reviewed 38 trials and 3 case reports of both men and women. Mild adverse events were reported by 279 
out of 1529 subjects and consisted of light headedness, vertigo, drowsiness, sleepiness, dry mouth, nasal 
irritation, runny nose, abdominal pain, anxiety, euphoria, increased energy, relaxation, calm sensation, and 
headache.  
 
In this study we propose to use intranasal oxytocin to examine its physiologic and metabolic effects. We propose 
to use the same dose as recently reported by Zhang et al. 2.  In this recently conducted study, 24 subjects were 
randomized to intranasal oxytocin (24 IU QID) or placebo for a period of 8 weeks.  They demonstrated that there 
was no cardiovascular, hepatic or renal dysfunction related to the use of intranasal oxytocin. In fact, they noted 
improved hepatic function in the oxytocin group.  Based on the review of the literature and recent published 
studies indicating the safe use of intranasal oxytocin, we feel that intranasal oxytocin can be safely administered 
in a research study to examine its physiologic effects such as we propose.  
 
2. Study Objective 
a) To assess the effect of intranasal oxytocin administration on body weight, adiposity, muscle mass, and 
glucose tolerance in older adults. 
b) To assess the effect of intranasal oxytocin on physical function and physiologic parameters of insulin 
signaling, inflammation, and muscle regeneration in older adults.  
 
3. Study Design 
3.1. Subjects 
Population: 36 obese (BMI 30.0-43.0 kg/m2) sarcopenic (see below) subjects aged ≥60 years will be 
randomized to either intra-nasal oxytocin or placebo (saline) for 8 weeks.  Oxytocin (Syntocinon; Novartis-
Switzerland via

Victoria Apotheke Zürich) will be dosed at 24 IU four times a day (before each meal and at bedtime)2. 
Additional inclusion criteria (as shown 
in Table 1), are stable body weight, 
sedentary lifestyle (within the last 6 
months), and sarcopenic obesity.  
 
Sarcopenic obesity is defined using a 
modified consensus criteria of gait 
speed <1 meter/second 12. Exclusion 
criteria are shown in Table 1.  Muscle 
mass will be measured as an outcome 
variable, however, it will not be used as 
a basis for inclusion. 
 
3.2. General Design 
 
Randomized, placebo controlled Phase 
II pilot study to be conducted at 3 
clinical sites: UTHealth San Antonio, 
UTHealth in Houston, and UTMB in 
Galveston. 
 
3.3. Study Endpoints 
 
Primary outcomes: Change in weight, adiposity,  
muscle mass, and physical function (gait speed, strength, SPPB). This is a pilot study which will examine 
change in these outcomes prior to and after treatment.  
 
Secondary outcomes:  Change in glucose 
tolerance as measured by OGTT, measures of 
systemic inflammation (TNF-α, C-reactive protein, 
IL-6, adiponectin), muscle inflammation (IL-1β, IL-6, 
MCP-1, TNF-α mRNA), and muscle stem cell 
number and proliferative capacity. This is a pilot 
study which will examine change in these outcomes 
prior to and after treatment. 
 
3.4. Potential Risks to Subject Safety

subject with a hematocrit of < 34% will not be studied.  Blood will be collected for safety and for research 
purposes at screening and study visits. Upon subject-reported history of any condition (known or suspected) 
that would be exclusionary, investigator may choose to order appropriate additional clinical labs to ensure 
eligibility.  
IV lines.   
Catheters will be placed in an antecubital vein or a hand vein for the OGTT.  Local hematomas occur in 
about 1% of catheterizations.  Infection is possible (<1%), but we have not experienced this complication.   
Muscle biopsy.   
At the time of biopsy, subjects may feel pain, discomfort, or pressure (variably described by different 
subjects) for about 5-10 seconds.  Pain or discomfort ceases as soon as the cannula is withdrawn.  Local 
hematomas occur in <2% of subjects.  One patient experienced a moderately painful hematoma that 
resolved within 2 weeks (0.1%).  About 1 in 50 subjects report non-clinically evident numbness or altered 
sensation at the biopsy site, which is transient.  
 
There is the possibility that a future biopsy may not be done at the discretion of the PI in case the subject 
did not tolerate well a prior biopsy. 
Radiation exposure. 
Subjects will be exposed to a small amount of radioactivity during DEXA.

UTMB and UTHealth-Houston. At some sites, subjects will call-in to an advertised number and will be pre-
screened using an institutionally-approved process. Callers then provide permission for a research team 
member to follow up with phone screening using an IRB-approved form (sample contained in Attachment D 
section) and staff will schedule the screening visit if the potential subject agrees If potentially eligible following 
the telephone screening process, an in-person screening visit will be conducted.   
 
Screening evaluation will follow informed consent at Visit 1 and will include: medical history, physical 
examination (including anthropometric measurements), Mini-Cog, and screening blood tests (complete blood 
count, chemistry, lipid profile, hemoglobin A1c, coagulation tests, urinalysis).

4.4. Early Withdrawal of Subjects 
4.4.1. When and How to Withdraw Subjects 
Subjects have the right to withdraw fully or partially from the study at any time and for any reason without 
prejudice to his or her future medical care by the physician or at the institution. 
 
Withdrawal of full consent for a study means that the subject does not wish to receive further investigational 
treatment and does not wish to or is unable to continue further study participation including any follow-up in 
person, by phone, through third parties including relatives or friends, via discussion with other treating 
physicians, and by use of medical records; subject data up to withdrawal of full consent will be included in the 
analysis of the study. Any subject may withdraw full consent to participate in the study at any time during the 
study. The Investigator or sub-investigator will discuss with the subject appropriate procedures for withdrawal 
from the study. 
 
Final Study Visit for Withdrawn Subjects 
At the time of receiving notification of intended withdrawal, researchers will ask subject to complete a final 
visit. The informed consent document advises subjects to discuss withdrawal decision with the principal 
investigator. This visit includes a repeat history and physical examination, weight, functional testing, 
Bioimpedance (UTMB site only), DEXA, questionnaires, and laboratory tests (safety labs, inflammatory 
markers). Subjects may choose to complete all or part of the final study visit. 
 
4.4.2. Data Collection and Follow-up for Withdrawn Subjects 
If subjects are withdrawn prematurely from the study, appropriately designated research staff will make efforts 
to collect at least survival data throughout the protocol defined follow-up period for that subject.  
 
Investigator will consult with Study Statistician with regard to any incomplete data set as compared to the full 
data set that fully supports the analysis.  If a subject withdraws consent to participate in the study, attempts will 
be made to obtain permission to record survival data up to the protocol-described end of subject follow-up period.  
 
Investigator and designated research staff make it a high priority to obtain survival data on all subjects lost to 
follow up. Lost to follow up will be defined as a subject missing 2 or more consecutive visits, not answering or 
responding to 3 follow up phone calls to subject or emergency contacts, or returned receipt of 1 certified letter.  
5. Study Drug 
5.1. Description 
See Attachment D. Victoria Apotheke Zurich: Syntocinon, Drug information

ID/Randomization number. Only the secure source documents may contain subject identifiers (name, DOB, 
SSN, etc.) 
5.3. Preparation and Administration of Study Drug 
Intranasal Administration Protocol. 
To prime a new bottle: 
• 
Hold the bottle upright and away from you, then pump it several times until you see a faint spray.  
• 
Do not prime the pump again before each daily use.  
 
To use the nose spray: 
• 
Before using the spray, blow your nose gently to clear the nostrils.  
• 
Keeping your head in an upright position, carefully place the nozzle into one nostril, aiming straight back 
toward the base of the skull. Do not aim the nozzle straight up toward the top of the head. 
• 
Press the pump toward the bottle and spray as directed.  
• 
Do not inhale while spraying. Breathe or sniff gently through the nose after spraying and do not blow 
nose again for at least 30 minutes. 
• 
To keep the nosepiece clean, wipe it with a clean tissue and replace the dust cap after use.  
 
Subject Compliance Monitoring 
A drug diary will be provided to all subjects at the time of drug dispensing at Visit 3 (or Visit 4 if optional MRI is 
completed). Subjects will be instructed to log their use of the study drug daily and bring the drug diary to each 
visit. 
5.4. Prior and Concomitant Therapy 
Exclusionary medications:  
Drugs that affect glucose homeostasis, systemic corticosteroids, androgens.  
Treatment with anticoagulants (warfarin). Aspirin (up to 325 mg) and clopidogrel will be permitted if these can 
be held for seven days prior to the biopsies.

status assessments (Mini-Cog and depression scale) will be performed to ensure valid consenting process. If 
subjects meet initial eligibility criteria based on walking speed and history & physical examination.  Individuals 
meeting eligibility will proceed to a 2-hour OGTT. During the 2-hour OGTT,  baseline testing will be performed, 
including labs, food recall and appetite assessments and psychometrics. After the 2-hour OGTT, the participant 
will be given a meal or substantial snack (per local clinical research unit) and continue with the functional testing. 
A screening window of 30 days is allowed so that all laboratory and test results can be returned and reviewed. 
Estimated length of this visit is 6 hours. 
• 
Vital signs will be assessed for blood pressure, heart rate, respiratory rate and temperature 
• 
Walking speed will be assessed at usual speed over a 15-foot course 
• 
Waist circumference will be measured in inches and converted to centimeters.  
• 
Weight in pounds will be measured or calculated in kilograms and used in BMI calculation. 
•

7. Statistical Plan 
7.1. Sample Size Determination  
Our power and sample size estimation is based on findings from an 8-week study of intranasal oxytocin in 24 
adults, which found a greater reduction in body weight and BMI with oxytocin. Based on their findings, our 
proposed study (12 completers each site for 36 completers total, 18 completers in each arm) is expected to 
have 96.4% power to detect the oxytocin effect if the standard deviation (SD) associated with weight loss is 
6.0 kg in the oxytocin group and 1.5 kg in the control group. For a more conservative estimate assuming a SD 
of 6.0 in both the oxytocin and control groups, our study would have 78.2% power. For both these power 
analyses, we assume type 1 error of P=0.05.  
 
7.2. Statistical Methods 
Analytical Approach. 
Generalized linear mixed effects model will be used to evaluate the effect of oxytocin on the change of each 
continuous measure.  The effect of oxytocin will be assessed by whether the time by oxytocin interaction is 
significantly different from 0 with a 2-sided p-value<0.05. Normal transformed score of an outcome will be used 
in the analyses when appropriate.  
 
8. Safety and Adverse Events 
8.1. Definitions 
Adverse Event (AE) 
In general, AE is used very broadly and encompasses physical and psychological harms and includes:   
 
Any untoward or unfavorable medical occurrence in a human subject, including any abnormal sign (for 
example, abnormal physical exam or laboratory finding), symptom, or disease, temporally associated with 
the subject’s participation in the research, whether or not it is considered related to the subject’s participation 
in the research. 
 
Intercurrent illnesses or injuries should be regarded as adverse events.  Abnormal results of diagnostic 
procedures are considered to be adverse events if the abnormality: 
• 
results in study withdrawal 
• 
is associated with a serious adverse event 
• 
is associated with clinical signs or symptoms 
• 
leads to additional treatment or to further diagnostic tests 
• 
is considered by the investigator to be of clinical significance 
 
Serious Adverse Event (SAE) 
Adverse events are classified as serious or non-serious.  A serious adverse event is any AE that:  
• 
results in death; 
• 
is life-threatening (places the subject at immediate risk of death from the event as it occurred); 
• 
results in inpatient hospitalization or prolongation of existing hospitalization; 
• 
results in a persistent or significant disability/incapacity; 
• 
results in a congenital anomaly/birth defect; or 
• 
based upon appropriate medical judgment, may jeopardize the subject’s health and may require medical 
or surgical intervention to prevent one of the other outcomes listed in this definition (examples of such

events include allergic bronchospasm requiring intensive treatment in the emergency room or at home, 
blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse). 
 
Unanticipated Problems Involving Risk to Subjects or Others (UPIRSO) 
Any incident, experience, or outcome that meets all of the following criteria:  
• 
Unexpected in nature, severity, or frequency (i.e. not described in study-related documents such as the 
IRB-approved protocol or consent form, the investigators brochure, etc.) 
• 
Related or possibly related to participation in the research (i.e. possibly related means there is a 
reasonable possibility that the incident experience, or outcome may have been caused by the procedures 
involved in the research) 
• 
Suggests that the research places subjects or others at greater risk of harm (including physical, 
psychological, economic, or social harm). 
 
Adverse Event Reporting Period 
The study period during which adverse events must be reported is normally defined as the period from the 
initiation of any study procedures to the end of the study treatment follow-up.  For this study, the study treatment 
follow-up is defined as 7 days following the last administration of study treatment.  
 
Pre-existing Condition 
A preexisting condition is one that is present at the start of the study.  A pre-existing condition should be recorded 
as an adverse event if the frequency, intensity, or the character of the condition worsens during the study period. 
 
General Physical Examination Findings 
At screening, any clinically significant abnormality should be recorded as a preexisting condition.  At the end of 
the study, any new clinically significant findings/abnormalities that meet the definition of an adverse event must 
also be recorded and documented as an adverse event.  
 
Abnormal Laboratory Values 
A clinical laboratory abnormality should be documented as an adverse event if any one of the following conditions 
is met:  
• 
The laboratory abnormality is not otherwise refuted by a repeat test to confirm the abnormality 
• 
The abnormality suggests a disease and/or organ toxicity 
• 
The abnormality is of a degree that requires active management; e.g. change of dose, discontinuation of 
the drug, more frequent follow-up assessments, further diagnostic investigation, etc. 
 
Hospitalization, Prolonged Hospitalization or Surgery 
Any adverse event that results in hospitalization or prolonged hospitalization should be documented and reported 
as a SAE unless specifically instructed otherwise in this protocol.  Any condition responsible for surgery should 
be documented as an AE if the condition meets the criteria for and adverse event. Neither the condition, 
hospitalization, prolonged hospitalization, nor surgery are reported as an AE in the following circumstances: 
• 
Hospitalization or prolonged hospitalization for diagnostic or elective surgical procedures for a preexisting 
condition.  
• 
Surgery should not be reported as an outcome of an adverse event if the purpose of the surgery was 
elective or diagnostic and the outcome was uneventful. 
• 
Hospitalization or prolonged hospitalization required to allow efficacy measurement for the study. 
• 
Hospitalization or prolonged hospitalization for therapy of the target disease of the study, unless it is a 
worsening or increase in frequency of hospital admissions as judged by the clinical investigator.

8.2. Recording and Reporting of Adverse Events and Protocol Deviations 
At each contact with the subject, the investigator or study staff will seek information about adverse events by 
specific questioning and, if appropriate, by examination.  The principal investigator will review the safety and 
progress of this study on a continuing basis. Safety data will be reviewed at each study visit. Information on all 
adverse events will be recorded immediately in the source document, and also in the appropriate adverse event 
section of the case report form.  
 
• 
AEs will be tracked using the HSC IRB AE tracking form or data management tool (See Section 9.3) to 
be reviewed by Site Investigator weekly and IND Sponsor monthly. 
 
• 
All AEs occurring during the study period will be recorded. The clinical course of each event will be 
followed until resolution, stabilization, or until it has been determined that the study treatment or 
participation is not the cause.   
 
• 
All adverse events will be summarized annually and submitted to the IRB.   
 
• 
Deviations from the approved protocol (PDs) will be recorded in the site Protocol Deviation Log. When a 
deviation occurs site investigators or research staff will notify the site IRB and the IND sponsor as 
appropriate per local policy and procedure. 
 
• 
The IND Sponsor records every PD in a study-wide log and reviews within 48 hours of notification to 
determine if prompt reporting to IRB of record  is required.  
 
8.3. Recording and Reporting of Serious Adverse Events and Unanticipated Problems 
 
SAEs and UPIRSOs will be reported per governing IRB policy and procedure. 
• 
UPIRSOs that are a result of study participation are reported to the IRB and the Medical Safety Officer 
within 24 hours. The report will include a description of the event, when and how it was reported, as well 
as any official chart records or documentation to corroborate the event or the reporting of the event. All 
adverse events will be graded as mild, moderate, or severe.   
• 
SAEs will also be submitted to the IRB and the safety officer within 24 hours.  
• 
SAEs that are still ongoing at the end of the study period will be followed up to determine the final outcome.  
Any SAE that occurs after the study period and is considered to be possibly related to the study treatment 
or study participation will be recorded and reported per Institutional policy and according to FDA 
requirements. 
 
Any action resulting in a temporary or permanent suspension of this study (e.g. local site IRB actions) will be 
reported to the IND Sponsor. 
Investigator reporting: notifying the IND sponsor 
Any study-related UPIRSO, and any type of SAE, must be reported to IND Sponsor by telephone within 24 hours 
of the event.  To report such events, a Serious Adverse Event (SAE) form must be completed by the investigator 
and faxed to IND sponsor within 24 hours.  The investigator will keep a copy of this SAE form on file at the study 
site.

9. Data Handling and Record Keeping 
9.1. Confidentiality 
Information learned about all subjects will be kept confidential.  All data and protected health information (PHI) 
in paper form will be kept confidential by assigned anonymous identifier and kept secured (password protected 
and/or double locked). Subjects will not be identified in any way in any publication.   
9.2. Source Documents 
Source data are contained in source documents found in paper subject files at the research site and in site 
electronic medical records.  If source data are handwritten, print all entries legibly in black ink.  Erasures and 
white-out material are prohibited. If any entry error has been made on paper, to correct such an error, draw a 
single straight line through the incorrect entry and enter the correct data above it.  All such changes must be 
initialed and dated.  For clarification of illegible or uncertain entries, print the clarification above the item, then 
initial and date it. 
9.3. Data Management 
 
Data System: REDCap 
All data will be input using a web front-end interface. All users are individually assigned authorization for access 
to specific components of the database application. Information that is input is checked for logical and range 
consistency and mandatory data fields must be entered in order to input a record. Reports are available as Excel 
exports to each site staff with access to reports. 
 
Case Report Forms 
CRFs will be developed in REDCap and may be printed in PDF for handwritten use. Radiology and lab reports 
may be printed or copied for use as source documents, while questionnaires and validated instruments may 
be copied from the Manual of Operations (MOP) for use in the paper research record. Data entry personnel 
will be appropriately trained before study is initiated. 
9.4. Records Retention 
The IND Sponsor is responsible for maintaining the Trial Master File by way of access to and storage in the 
eRegulatory Binder at Clinical Trials Express. 
 
The local site Principal Investigator is responsible for maintaining study essential documents for at least 3 years 
after study participation ends for the last subject at the last site, or according to the IND Sponsor’s institutional

retention period, whichever is greater.  
 
These documents should be retained for a longer period if required by a funding agency, the FDA or other 
institutional retention policy.  In such an instance, it is the responsibility of the IND Sponsor to inform the 
investigator/institution as to when these documents no longer need to be retained.  
 
10. Study Monitoring, Auditing, and Inspecting 
10.1. Study Monitoring Plan 
The Sponsor will ensure that the designated study monitor, compliance specialist or other quality assurance 
reviewer is given access to all the above noted study-related documents and study related facilities (e.g. 
pharmacy, diagnostic laboratory, etc.), and has adequate space to conduct the study monitoring visits. 
 
Monitoring elements will be reviewed at least once during the study period as described below: 
• 
Consent process 
• 
Accuracy of the collection and processing of laboratory specimens  
• 
Forms and source documents in the subjects’ research records will be current and maintained in a timely 
manner. 
• 
Physical and mental condition of the subject and any type of AE will be assessed and monitored prior to 
beginning the study by the investigator(s) and staff, and during the study period. 
 
Areas of focus for study monitoring by the designated study monitor: 
• 
Regulatory documentation and compliance with local policy will be monitored once during the study period 
at each site.  
• 
The safe handling and accountability of drugs, which includes the use of temperature logs and disposal 
of waste, will be maintained upon receipt of study drug, upon dispensing, and at the close out of the study 
period. 
• 
Compliance with the protocol and conduct of the study, including the consenting process, along with 
source data compared to collected data (SDV), will be monitored once at each site during the study period.  
– 30% of subject records and 100% of primary outcome data for each subject at each site will be 
monitored.  
– The first and the last subject enrolled will be monitored for consent practices and 100% of eligibility 
data collected. 
• 
Adverse event logs will be monitored and research records analyzed for AEs that were overlooked or 
otherwise not documented properly in the study files. 
• 
The safety assurance and condition of any electrical, radiological, magnetic, gaseous, and hazardous 
equipment, tools or apparatus that will be used by the investigators and subjects at each site will be 
properly maintained and certified by the site’s biomedical safety staff on at least an annual basis. The 
local site PI will attest to this assurance prior to enrolling the first subject. 
 
10.2. Auditing and Inspecting 
The site Investigator will permit study-related monitoring, audits, and inspections by the IRB, the funding 
sponsor, government regulatory bodies, and University compliance groups of all study related documents (e.g. 
source documents, regulatory documents, data collection instruments, study data etc.).  The site investigator 
will ensure the capability for inspections of applicable study-related facilities (e.g. pharmacy, diagnostic 
laboratory, etc.). 
 
Participation as a site investigator in this study implies acceptance of potential inspection by government
