SECTION V: RESEARCH PLAN
1. Statement of Purpose: State the scientific aim (s) of the study, or the hypotheses to be 
tested. 
To determine the effect of one dose of morphine, naltrexone and placebo on brain activity in 
healthy participants and patients suffering from pain.
To determine whether the effect of one dose of morphine, /naltrexone and placebo on brain 
activity in healthy participants and patients suffering from pain is different depending on 
Single Nucleotide Polymorphism (SNP) at the gene loci coding for opiate and dopamine 
related neurotransmission.  
To relate brain response to morphine to performance on reward related decision-making 
tasks.
2. Background: Describe the background information that led to the plan for this project. 
Provide references to support the expectation of obtaining useful scientific data.
Opiate medications such as morphine are potent analgesics and frequently used in the 
treatment of chronic non-cancer pain despite the absence of benefits in randomized clinical trials 
on pain relief when compared to placebo beyond 3-4 months of treatment 1. Treatment with 
opiates put patients at risk of weight gain 2,3, falls 4, overdose, abuse and long-term dependence 5.
Opiate intake has been particularly associated with a shift in the diet towards increased sugar 
and highly palatable food intake and long-term weight gain 6,7. In addition, opiate antagonist 
such as naltrexone is used to prevent binge eating behavior in humans, which is a major 
contributor to obesity 8. Extensive animal research is consistent with a major role of μ-opiate 
agonist in feeding in the absence of hunger (i.e. hedonic feeding) (comprehensive reviews in 
9,10).  Binding of μ-opiate agonist in the ventral striatum and amygdala causes hyperphagia in 
non-hungry animals and shifts their preference towards highly palatable fat 11,12. 
Chronic low back pain (CBP) is associated with obesity 13-17; however, the contribution of 
opiate prescriptions to increased body weight is still unknown.  Our preliminary data show that 
CBP patients treated with opiate based medications have a decreased brain response to 
milkshake when compared to CBP patients not on opiate in the whole insular cortex and primary 
somatosensory motor areas (Figure 1). This suggests that CBP patients on opiates might have a 
decreased orosensory experience during food ingestion since insula contains the primary taste 
cortex 18 and integrates taste perception with internal state such as hunger or pain 19. This 
decreased perception of food might in turn lead to long-term weight gain.
Given the lack of studies comparing brain response of CBP patients treated with opiate 
medications during food ingestion to CBP patients without opiate treatment we cannot tell 
whether the functional changes we observe in Figure 1 are due to an acute effect of opiate 
medications or due to a long-term adaptations to these drugs.  It is therefore possible that acute

APPROVED BY THE YALE UNIVERSITY IRB 1/5/2018 VALID THROUGH 8/8/2018
Page 10 of 52
administration of opiate may at first lead to increased response to milkshake that would later 
adapt and decrease upon chronic administration.
Binding of morphine in the brain of healthy participants occurs in areas rich in opioid receptors 
including ventral striatum, amygdala, and medial prefrontal cortex 20-22. These areas have been 
shown to mediate reward related decision making including food 23-25 money, and goods 26,27.  In 
addition, there is evidence that morphine binding in these areas strongly modulates deicision 
making about food 28 and money29. Hence, it stands to reason that inter-individual response 
differenes to one dose of morphine could relate to inter-individuals differences on reward related 
decision-making. 
Therefore, as a first step, we would like to understand the effect of acute administration 
of a μ-opiate agonist (i.e. morphine), a μ-opiate antagonist (i.e. naltrexone) on brain activity at 
rest and in response to food in comparison to the administration of a placebo in a double blind 
design.  Also we would like to study the acute effects of opioid (morphine) administration in an 
open label arm. We are adding this arm to generate preliminary results to study the effect of 
Morphine using a simpler and less time consuming protocol where participation would be easier 
for subjects. We will relate performance on gambling, motivational and risk taking tasks to brain 
response to morphine.
 In addition, we would like to factor in individual genetic differences in dopamine and opiate 
neurotransmission since these are well known to affect brain response to opiates 20,30.

Figure 1.  Results of a T-test comparison of brain response to milkshake (corrected for tasteless) 
between 6 CBP patients taking opiates and 7 CBP patients not taking any analgesic medications. 
The two groups did not differ on their ratings of pain intensity. Results shown at Z > 2.3 and p < 
0.05 corrected for multiple comparisons and using random effects model. We observed 
decreased brain response with opiate treatment in the right insula, primary somatomotor/sensory 
areas and frontal operculum. 
3. Research Plan: Summarize the study design and research procedures using non-technical 
language that can be readily understood by someone outside the discipline. Be sure to 
distinguish between standard of care vs. research procedures when applicable, and 
include any flowcharts of visits specifying their individual times and lengths. Describe 
the setting in which the research will take place.

Procedure:
A. Description of the of the procedures for the double blind placebo controlled arm
Day 1) Phone screening 
During an initial telephone conversation, we will provide a brief description of the study, do an 
initial screening of the subject to ensure that they meet inclusion criteria and do not possess any 
of the exclusion criteria, and schedule the subject's intake session.  
Day 2) Intake session
Subject comes to The John B Pierce Laboratory where written informed consent will be 
obtained. The subject will be asked to refrain from alcohol use the day before any session. The 
subject then completes a subset of the following intake measures to determine eligibility:  
A. Toxicology/pregnancy screening
We will perform the following screens:
i.
Breath alcohol levels will be assessed with the Alcohawk Elite Breathalyzer. 
ii.
Urine toxicology screens will be conducted using the Integrated E-Z Split Key Cup II 
(Innovacon Inc., San Diego, CA) for opiates, cocaine, THC, PCP and barbiturate. 
iii.
We do not wish to study females who may be pregnant.  Therefore, all females of 
childbearing potential will be given a urine pregnancy test.
If a subject tests positive on any of these screens they will be informed of the result and excluded 
from further participation in the study. The results from these tests will not be recorded for 
subjects who are excluded for positive results.
Genotyping:
We will collect a saliva sample to genotype for SNPs related to dopaminergic and opiate 
signaling in the brain. The gene loci tested and their SNPs are attached.
Iowa Gambling Game: 
Iowa Gambling Task31: Designed to evaluate the ability to postpone immediate reward for a 
longer-term successful outcome, tests emotional decision-making ability. Subjects play a card 
game under conditions of limited knowledge about reward and penalty. The participant is 
presented with 4 decks of card.  Two decks are advantageous (A and B); A and B do not give big 
gains but do not lead to losses after 100 draws.  Two decks are disadvantageous (C and D).  C 
and D give big gains but end up 
leading to big losses after 100 draws.  
Patients 
with 
inability 
to 
delay 
immediate gratification to improve 
long-term outcomes perform badly on 
this task.   The gains and losses will be 
in fake Monopoly money.

Effort Expenditure for Rewards (EEfRT) 
The EEfRT 32task is a multi-trial game in which participants are given an opportunity on each 
trial to choose between two different task difficulty levels in order to obtain monetary rewards 
(see Figure) For all trials, participants made repeated manual button presses within a short period 
of time. Each button press raised the level of a virtual “bar” viewed onscreen by the participant. 
Participants are eligible to win the money allotted for each trial if they raised the bar to the “top” 
within the prescribed time period. Each trial presented the subject with a choice between two 
levels of task difficulty, a ‘hard task’ and an ‘easy task’. Successful completion of hard-task 
trials required the subject to make 100 button presses, using the non-dominant little finger within 
21 seconds, while successful completion of easy-task trials required the subject to make 30 
button presses, using the dominant index finger within 7 seconds.
For easy-task trials, subjects are eligible to win the same amount, $1.00, on each trial if they 
successfully completed the task. For hard-task choices, subjects are eligible to win higher 
amounts that varied per trial within a range of $1.24 – $4.30 (“reward magnitude”). Subjects are 
not guaranteed to win the reward if they complete the task; some trials are “win” trials, in which 
the subject receive the stated reward amount, while others are “no win” trials, in which the 
subject receive no money for that trial. To help subjects determine which trials are more likely to 
be winning trials, subjects are provided with accurate probability cues at the beginning of each 
trial. Trials had three levels of probability: “high” 88% probability of being a win trial, 
“medium” 50% and “low” 12%. Probability levels always applied to both the hard task and easy 
task, and there are equal proportions of each probability level across the experiment. Each level 
of probability appeared once in conjunction with each level of reward value for the hard task. All 
subjects received trials presented in the same randomized order.
All trials begin with a 1-second fixation cross, following a 5-second choice period in which 
subjects are presented with information regarding the probability of receiving reward and the 
reward magnitude of the hard task. Subjects are told that if they did not make a choice within 5 
seconds, they would be randomly assigned to either the easy or the hard task for that trial. After 
making a choice, subjects are then shown a 1-second “Ready” screen and then completed the 
task. Following task completion, subjects are shown a 2 second feedback screen informing them 
that the task was successfully or unsuccessfully completed. If subjects successfully completed 
the task, then a second feedback screen appeared for 2 seconds in which subjects are told 
whether they had won money for that trial (reward feedback). In total, easy-task trials took 
approximately 15 seconds, whereas hard-task trials took approximately 30 seconds.
Subjects are told that they would receive a base-rate of compensation for their participation. In 
addition, they are told that two of their win trials would be randomly selected at the end of the 
experiment as “incentive trials,” for which they would receive the actual amount won on those 
trials. Subjects are informed that they had twenty minutes to play as many trials as they could. 
Since hard-task trials take approximately twice as much time to complete as easy-task trials, the 
number of trials that the subject was able to play depended in part on the choices that he or she 
made. This meant that making more hard-task trials toward the beginning of the experiment 
could reduce the total number of trials, which could in turn mean that the subject would not get a 
chance to play high-value, high-probability trials that might have appeared towards the end of

the playing time. This trade-off will be explained clearly to the subject. Importantly, subjects are 
not provided with any information regarding the distribution of trial types. The goal of this trade-
off is to ensure that neither a strategy of always choosing the easy or the hard option could lead 
to an ‘optimal’ performance on the task. Moreover, the complexity of variables (with varying 
monetary reward levels, probability, and loss of time for future trials), does not lend itself to a 
formal calculation of an optimal response selection, and subjects are required to make decisions 
within a brief amount of time. This was done to help ensure that subject decisions reflected 
individual differences in the willingness to expend effort for a given level of expected reward 
value.  At the end of the experiment the subjects will receive the accumulated earnings in real 
money.
The EEfRT was programmed in Matlab (Matlab for Windows, Rel. 2007b. Mathworks Inc., 
Natick, MA) using the Psychtoolbox version 2.0.

procedure and are required to pass task 
comprehension questions before completing 
practice trials. In the experiment itself, 
participants will be first given $100 
endowment to start playing. They will make 
60 binary choices between a certain gain of 
$5 and a bet of a monetary value (20 
amounts: $5–$20 in gains or losses) and 
probability of payout or loss (3 levels: 0.25, 0.5, 0.75) are systematically manipulated. Each trial 
will be represented by an image of a bag containing 100 colored poker chips, some red and some 
blue (See Figure); these images corresponded to physical bags that are present in the 
experimental room. The size of the colored areas and the numbers written inside indicate the 
number of chips of each color in the bag. Above and below each color, a number indicate how 
much a chip of that color would be worth if it are drawn from the bag.  Trial order will be 
randomized independently for each participant.  At the end of the experiment the subjects will 
receive the accumulated earnings in real money if they win money in addition to the $100.  If 
they lose money they will still receive a $100 for participation. 
Equipment training:
fMRI training
Subjects will be asked to lie in our fMRI simulator and will be outfitted with the taste 
delivery device and earphones that will play simulated fMRI scanner noises. The simulator 
consists of a padded table on which the subject lies supine. A removable wooden replica of 
the fMRI headcoil is placed over the subjects’ head. The gustatory manifold is anchored to 
the simulated headcoil. New tubing and syringes are used for each subject and the

mouthpiece and nasal mask are cleaned and sterilized between uses by boiling in a 10% 
bleach solution for 15 min.  In the simulator and in the actual fMRI scanner subjects will 
receive liquids through an fMRI compatible custom designed gustometer built by Dr. Small 
(in collaboration with colleagues in the Pierce shop). In brief, the gustometer consists of a 
computer running Matlab, controlling a series of programmable syringe pumps with 60ml 
syringes and beverage tubing attached and leading to a mouthpiece (gustatory manifold) held 
in place by anchoring to the fMRI headcoil. This set up has been used successfully by Dr. 
Small’s lab for the past 9 years33-35. All subjects will undergo a 10-minute mock fMRI run in 
which they receive the following stimuli:  sucrose, tasteless, and milkshake. The purpose of 
this mock run is to familiarize subjects with the procedures of the fMRI experiment and to 
teach subjects how to comfortably swallow while lying on a bed made to look like the MR 
scanner. Most people have no difficulty learning to swallow small quantities of liquid while 
lying down. Subjects who have difficulty with supine swallowing, who are uncomfortable in 
the simulated MRI environment, or unable to swallow without excessive movement will not 
be asked to continue participating in the studies. This procedure takes 30 minutes. 
Meeting with the Physician and discussion of drug side effects:
Each participant will meet with Dr. Paul Geha to go over the possible side effects of 30 mg 
of Morphine, 50 mg of Naltrexone and placebo given at one dose.  Dr. Geha will go over the 
most common side effects and will emphasize the risk of altered mental status (e.g. 
sleepiness, drowsiness) after one dose of morphine. Dr. Geha is Yale trained psychiatrist and 
will collect psychiatric history on possible previous misuse of alcohol, illegal drugs and 
prescription drugs.  Any subject with such previous history will be excluded from the study.  
In addition, each participant will be given a patient information sheet about each of the 
medications used in the study.
To avoid fatigue subjects will take a 5-minute breaks every 15-20 minutes. This session takes 
about 2 hours. If the subject meets all eligibility criteria we will schedule them for a Pre-
supplementation session at The John B Pierce Laboratory. 
Measurment of body fat composition:
We will measure body fat composition of our participants; body fat and body mass index can be 
confounding in our analysis given that brain response to food is different between obese and 
healthy weight participants36.  The BodPod body composition tracking system is an air 
displacement plethysmograph which uses whole-body densitometry to determine body 
composition (fat and fat-free mass).The BodPod is an egg-shaped pod that consists out of two 
chambers. The front, or Test chamber, is where the subject sits and is comprised of a seat that 
forms a common wall separating it from the rear, or reference chamber. During the brief data 
collection period of the volume measurement, the chamber door is secured by a series of 
electromagnets and a gasket. A diaphragm is mounted on the common wall, which oscillates 
during testing. This causes small changes in volume inside the chamber, of which the pressure 
response to these small volume changes is measured. This is done by measuring the interior 
volume of the empty BodPod chamber, then measuring it again when the subject is seated inside. 
By subtraction, the subject's body volume is obtained. Once the subject's mass and volume are 
determined, body density is calculated and the relative proportions of fat and fat-free mass are 
determined. Thus this procedure is entirely non-invasive. A complete test requires about 5

minutes for which the subject will be asked to change into spandex undergarments, that are 
provided by the Small lab. The interior of the BodPod accommodates a wide variety of human 
shapes and sizes, including subjects up to 7 feet tall and 550 pounds. The egg-shaped design of 
the BodPod maximizes interior space, and can be used routinely for testing a wide variety of 
subjects, including special populations such as obese subjects. The BodPod's precision, accuracy, 
and reliability have been validated through independent research studies with various subject 
populations. The Bioelectric Impedance Analysis device (BIA) uses the flow of various low 
alternating electrical currents and measures impedance.  It produces estimates of total body 
water, extracellular water, fat-free mass and lean soft tissue for each limb and torso. It consists of 
a weighing platform that also contains foot electrodes (that the subject steps onto) and a bar with 
finger electrodes (that the subject holds onto with their hands). A complete measurement takes 
under 1 minute and does not require a subject to change into separate garments. This system is 
routinely used in hospitals, medical practices and inpatient care facilities in accordance with 
regulations. The BIA’s precision, accuracy and reliability have been validated through 
independent research studies.
Below is a list of questionnaires subjects will fill out and a description of the food reinforcement 
test:
Binge Eating Scale (BES): The BES is a 16-item questionnaire that will assess behavioral 
manifestations and feelings surrounding a binge episode . 
Dutch Eating Behavior Questionnaire (DEBQ): The DEBQ (33 items) will be used to assess 
emotional eating, externalizing, and dietary restraint.
Three Factor Eating Questionnaire (TFEQ): This 58-item questionnaire will be used to obtain 
a score on the subscales of “cognitive control of eating”, “disinhibition”, and “susceptibility to 
hunger”37.
International Phsyical Activity Questionnaire (IPAQ): the IPAQ is a 27-item questionnaire 
that will be used to obtain an estimate of physical activity 38.
Pittsburgh Sleep Quality Index (PSQI): the PSQI is a 19-item questionnaire with a global 
score and subscales that include sleep quality, latency, duration, sleep efficiency, disturbances, 
hypnotic use, and daytime dysfunction 39.
Dieting and Weight History Questionnaire: This questionnaire will be used to assess history 
of weight and weight loss attempts.
Power of Food Scale (PFS): The PFS is an 18-item questionnaire that will asses the 
psychological influences of food environment 40.
Night Eating Questionnaire: This 16-item questionnaire will be used to characterize night 
time eating behaviors 41. 
Phenotype Questionnaire: 11-item questionnaire that assesses individual eating habits and 
attitudes towards food.
The Behavioral Inhibition System/Behavioral Activation System (BIS/BAS; will assess 
behavioral activation and behavioral inhibition which have been proposed as biological systems 
underlying behavior and affect. The Behavioral Inhibition assesses sensitivity to punishment 
(BIS scale) and three subscales tap different components of behavioral activation (Reward 
Responsiveness, Drive and Fun Seeking). This measure has been shown to have good 
convergent, discriminant, and predictive validity in which the instrument measures sensitivity 
rather than the person’s typical experiences.  The Behavioral Inhibition Scale will be used to tap 
the component of impulsivity related to decreased sensitivity to the negative consequences of

Day 3) fMRI scan session
1. Upon arrival to the Magnetic Resonance Research Center (MRRC) participants a urine drug 
test will be obtained as well as Breath alcohol levels will be assessed with the Alcohawk 
Elite Breathalyzer.  If any of these tests are positive the study will be cancelled.  Next, vitals 
signs (VS)(blood pressure, heart rate, respiratory rate, pulse oximetry, and temperature).  If 
the urine drug test is positive for opiates or methadone the study will be cancelled and the 
subject disqualified for this study. 
2. Participants with BP < 90/60 and/or heart rate < 60 will be excluded and the study will be 
cancelled.  VS will be logged in to a VS sheet and kept with the participant paper record in 
our study binders.  Mental and neurologic status will be assessed for a baseline using the 
National Institutes of Health (NIH) Stroke Scale Neurological Assessment flow sheet (see 
attached form).
3. Next  20 ml of blood will be withdrawn.   All blood samples will be placed in pre-chilled test 
tubes, and centrifuged at 4 C and the plasma stored at -70 C until analyzed according to 
standard procedures in the YCCI Core Laboratory
4. Next, participants will be undergo fMRI scanning:
fMRI session: Set up is as above for fMRI simulator in fMRI training. Prior to getting the 
subject into the MR-room all people involved with the study walk through a detector 
designed to detect metal objects. We will use a Siemens 3T Trio TIM scanner with a 32-
channel head-coil. A T1-weighted 3D MPRAGE sequence (4 minutes) will be performed to 
obtain a high-resolution anatomical image and echoplanar imaging will be used to measure

the BOLD signal as an indication of cerebral activation in response to various tastes 
(milkshake and tasteless) during two 9.6-minute runs and in response to sucrose and tasteless 
during two 9.6-minute runs. A run consists of multiple blocks of taste (milkshake or 
tasteless). One block is a series of 4 – 8 presentations of tastes or tasteless; Each presentation 
starts with a 0.75 cc delivery of liquid over 2 s followed by 7 s in which to swallow. Each 
taste block is followed by a rinse (0.75 cc deionized water). Before the start of a new block 
there is a rest period of 10 seconds. Blocks vary in length between 32 and 80 seconds and the 
order of blocks is counterbalanced across subjects. This design is modified from prior event-
related designs so as to yield a 61% improvement in design efficiency (calculated by 
FMRIB’s software library FSL), which we confirmed to lead to more extensive and more 
intense BOLD response. The data can be analyzed offline and used for experimental control 
variables. Next, two 6 minutes resting state runs will be collected.  During these runs, 
participants  will be asked to stare at a cross-hair on the screen. Finally, a diffusion tensor 
imaging (DTI) scan will be obtained over 5 minutes.
5. Participants will be then taken out of the scanner and given one oral dose of either 30 mg of 
Morphine, or 50 mg of Naltrexone or placebo. 60 minutes later, VS will be collected again 
and logged in to the VS sheet and participants will undergo another scanning session while 
receiving milkshake, sucrose or tasteless solutions as described in 3 and while at rest.  DTI 
and structural imaging will not be repeated. Blood pressure and heart rate will be 
continuously monitored during scanning using the Biopac system. The same procedure 
will be followed for the same participants in two subsequent visits (Day 4 and Day 5). The 
visits will be scheduled within a 
period spanning 4 weeks but no 
two-treatment 
days 
will 
be 
scheduled less than 48 hours 
apart. The overall design of the 
study will follow the illustration in 
Figure 1.  However, the order of 
the interventions (i.e. Morphine, 
Naltrexone or placebo) will be 
randomized. The scanning session 
after 
medication 
administration 
will last between 45-60 minutes.  
Participants vital signs and mental 
and neurological state will be monitored for an additional 2 hours post-scanning at an interval 
of one hour using the NIH Stroke Scale Neurological Assessment flow sheet (two 
assessments in total); after 2 hours, if participants mental and neurologic state and VS are 
stable they will be reminded about side-effects of morphine and naltrexone and released. 
Morphine sulfate half-life is 2-4 hours.  By the time our participants leave the MRRC one to 
two half-lives would have passed and the blood level of morphine would have dropped 2 to 4 
times relative to time at ingestion.

The same procedures described in A will be used to study 15 CBP patients using an 
open label design except when participants are taken to the scanner.  At that point both 
the experimenter and the participant will know that morphine 30 mg  is being 
administered. In addition, this arm of the study will have one arm only.
4. Genetic Testing   N/A 
A. Describe
i.
the types of future research to be conducted using the materials, specifying if 
immortalization of cell lines, whole exome or genome sequencing, genome wide 
association studies, or animal studies are planned.
No future research is planned with the materials. We will determine the presence or 
absence of candidate opiate activity-related genes after the subject has provided their 
saliva.
ii. the plan for the collection of material or the conditions under which material will 
be received
The Oragene-DNA Self-Collection Kit (vial format) will be used to collect DNA 
samples. This kit is an all-in-one system for the collection, preservation, and 
purification of DNA from saliva. The subjects will be asked to deliver the saliva in 
the container of the kit. After the delivery, the container will be capped which results 
in releasing DNA-preserving fluid that mixes with the saliva. This way, the DNA can 
be stored for long-term at room temperature. After collection, the DNA samples will 
be coded by a numeric code. This numeric code corresponds with the numeric code 
given to that particular subject in the study. The DNA samples will be analyzed in 
this lab using standard DNA procedures. Different sequence regions will be analyzed 
from each of the genomic DNA samples. The sequences will first be amplified using 
polymerase chain reaction (PCR) techniques, based on primer sequences specific for 
each sequence of interest. The amplified PCR products will then be digested with 
restriction enzymes as appropriate and analyzed using agarose gel electrophoresis. 
Images of each processed gel will be taken using a cooled-CCD camera system 
(ChemiDoc, Bio-Rad) and the presence or absence of a given allele will be 
determined based on the predicted sizes of the PCR products. 
iii. the types of information about the donor/individual contributors that will be 
entered into a database
No protected health information (PHI) will be kept with the DNA samples. Only 
authorized staff will have access to the password-protected file that links name and 
ID number on a secure server. The genetic data will be used in analyses with 
information participants provided during the previous behavioral and fMRI 
sessions, which includes demographic information, body mass index, dietary habits, 
ratings, and brain imaging data (but no PHI data). By linking these data, the genetic

information should provide insight into understanding differential brain response 
among individuals. 
iv. the methods to uphold confidentiality
The collected DNA samples will be stored at The John B. Pierce Laboratory. Only 
authorized study personnel may remove the samples for analysis. Data will be kept 
on the password-protected server for a period of seven years to ensure that the 
researchers have access to results. After seven years, the identifying data will be 
destroyed.
B. What are the conditions or procedures for sharing of materials and/or distributing for 
future research projects?
N/A . We do not plan to share of distribute these materials for future research 
projects.
C. Is widespread sharing of materials planned?
N/A
D. When and under what conditions will materials be stripped of all identifiers?
The materials are stripped of PHI after collection and coded with a subject ID 
number. After seven years, the identifying data will be destroyed. 
E. Can donor-subjects withdraw their materials at any time, and/or withdraw the identifiers 
that connect them to their materials?
i.
How will requests to withdraw materials be handled (e.g., material no longer 
identified: that is, anonymized) or material destroyed)?
Yes, subjects can withdraw their materials at any time by contacting the PI, a 
procedure described in the consent form. If a subject wished to withdraw their 
materials, we will locate the material by the subject ID by accessing the password 
protected file that links name and ID, and destroy the biological material and any 
paper or electronic record of their genetic information. The saliva sample will be 
destroyed and the raw data from these samples will be destroyed by soaking the 
sample in bleach. This will remove all DNA. We will also remove the subject from 
any analyses.
F. Describe the provisions for protection of participant privacy
No PHI will be kept with the DNA samples. Only authorized staff will have access to 
the password-protected file that links name and ID number on a secure server.

G. Describe the methods for the security of storage and sharing of materials 
Only authorized staff will have access to the password-protected file that links name

server for a period of seven years to ensure that the researchers have access to 
results. After seven years, the data will be deleted by zeroing with software as in 
accordance with policies and procedures as determined by Yale University 
(procedures 1609 and 1610).
5. Subject Population: Provide a detailed description of the types of human subjects who will 
be recruited into this study.
The subjects will be healthy human adults, and human adults suffering from pain 
conditions such as low back pain, knee arthritis, or fibromyalgia with normal gustatory 
and olfactory function and no medical conditions that would preclude them from being 
tested in the MR scanner. These subjects will be recruited from the Yale University 
Community, including undergraduate students, graduate students, and staff, with an 
age range between 18 and 65 years. Women and minorities will be encouraged to 
participate in all proposed experiments. We will monitor the subject pool periodically 
to ensure appropriate representation of all ethnic backgrounds and both sexes. 
6. Subject classification: Check off all classifications of subjects that will be specifically 
recruited for enrollment in the research project. Will subjects who may require additional 
safeguards or other considerations be enrolled in the study? If so, identify the population of 
subjects requiring special safeguards and provide a justification for their involvement.

Healthy participants
Patients in pain: suffering from persistent pain more days than not, 3/10 in intensity on a 
numerical rating scale, for at least 6 weeks or more.
Exclusion criteria: Any DSM diagnosis, diabetes, food allergies, lactose intolerance, 
participants seeking to quit smoking or to lose weight, participants on any psychotropic 
medication including opiate based analgesics (e.g. oxycodone, methadone, suboxone), 
pregnant or nursing women, pacemaker or other implanted electrical devices. Participants 
with a past history of head trauma or seizures will be excluded.  Any past history of illegal 
drug or alcohol misuse will be an exclusion criterion.
8. How will eligibility be determined, and by whom? 
Eligibility will be determined by the research coordinator upon initial telephone contact 
using a screening form (see attached phone screening form). The form asks general 
information questions (date of birth, handedness, native language, etc.) and queries the 
participants about their health and any history of conditions known to affect cognitive 
functioning (e.g. stroke, medications, head trauma), or any conditions that could 
compromise the safety of conducting an MRI scan (e.g. claustrophobia, metal in the 
body, pacemaker). A more lengthy MRI safety screening form will be administered 
when the participant arrives for the scanning session (see attached MRI screening 
form) at the Magnetic Resonance Research Center in the Congress Avenue building of 
Yale School of Medicine.  We do not wish to study females who are or may be pregnant.  
Therefore, as part of our MRI safety screening protocol, all females of childbearing 
potential will be given a urine pregnancy test prior to scanning.  Results of the 
pregnancy test will be given to them only and will remain confidential.  If the results 
indicate a subject is pregnant she will not participate in the fMRI scan, and will be 
excluded from the study.
9. Risks: Describe the reasonably foreseeable risks, including risks to subject privacy, 
discomforts, or inconveniences associated with subjects participating in the research. 
Risk involved with the questionnaires 
It is possible that interviews may cause distress or concern to the participants. One potential 
risk to participants is that it may be distressing to disclose information about psychiatric 
difficulties such as previous history of substance misuse. In our estimation, there is a low risk 
of this possibility and the effects would probably be short lived. We have conducted several 
hundred of these interviews with no adverse effects. It is possible that subjects may become 
frustrated with some of the impulsivity or cognitive assessments. We have conducted 
hundreds of similar cognitive assessments and have had no adverse outcomes. 
Risks involved with the mock fMRI scanner

NCT04342130


APPROVED BY THE YALE UNIVERSITY IRB 1/5/2018 VALID THROUGH 8/8/2018
Page 22 of 52
It is also possible that subjects report feeling uncomfortable in the mock scanner, either 
because they feel claustrophobic or because they do not like swallowing in a supine position. 
Subjects will be instructed to tell the experimenter if they feel any discomfort with the 
procedure so that the session can be terminated. We have conducted hundreds of fMRI 
training sessions. Approximately 1 in 15 subjects report some discomfort with this procedure 
and the sessions are terminated. We have had no adverse events.
Risks associated with one dose of oral 30 mg Morphine:
Morphine is an opiate agonist and has been used clinically for centuries. There is no clear 
compelling evidence of long-term toxicity from using one dose of 30 mg oral morphine. 
However, there are acute medical and neuropsychiatric sequelae that deserve special 
consideration.  Acute administration can lead to dizziness, somonolence, dysphoria, altered 
mental status, euphoria, edema, diaphoresis, headache, parasthesias, flushing, respiratory 
depression, hypotension, rash or pruritis, nausea, constipation and vomiting.  Very serious 
but extremely rare side effects include anaphylaxis, apnea, severe bradycardia or 
hypotension, or shock.
Risks associated with one dose of oral 50 mg Naltrexone:
Naltrexone is an opiate antagonist and has been used clinically for several decades. There are 
no long-term side effects of one dose of oral naltrexone; in fact, naltrexone is prescribed 
daily for alcohol misuse disorder to prevent relapse into drinking. Acute administration can 
be associated with insomnia, dizziness, fatigue, somnolence, headache, anxiety, abdominal 
pain, nausea, vomiting.  Extremely rare side effects include hypersensitivity reaction and 
hepatotoxicity. 
Risks involved with MRI
MRI and MRS are considered to be among the safest ways to examine the human body.  
They use magnetism and radio waves, not x-rays, to measure chemicals and take pictures of 
various parts of the body.  The United States Food and Drug Administration (FDA) has set 
guidelines for magnet strength and exposure to radio waves, and we carefully observe those 
guidelines.  For subjects’ exposure in this study, no bad effects have been seen.  This study 
has no painful parts.  Subjects will be watched closely throughout the study.  Some people 
may feel uncomfortable or anxious during the MRI or MRS.  If this happens to a subject, 
they may ask to stop the study at any time and we will take him/her out of the MR scanner.  
On rare occasions, some people might feel dizzy, get an upset stomach, have a metallic taste 
or feel tingling sensations or muscle twitches.  These sensations usually go away quickly but 
subjects should tell the research staff if they have them.  
MRI and MRS pose some risks for certain people.  If subjects have a pacemaker or some 
metal objects inside their body, they may not be in this study because the strong magnets in 
the MR scanner might harm them.  Another risk is a metallic object flying through the air 
toward the magnet and hitting them.  To reduce this risk we require that all people involved 
with the study remove all metal from their clothing and all metal objects from their pockets.

Nothing metal can be brought into the magnet room at any time.  Also, once a subject is in 
the magnet, the door to the room will be closed so that no one from outside accidentally goes 
near the magnet.
We want subjects to read the questions on the MR Safety Questionnaire and answer them 
very carefully.  Those questions are for their safety.  Subjects should take a moment to be 
sure that they have read the MR safety sheet and be sure to tell us any information they think 
might is important.  Even if they think that it is probably okay, we would rather have them 
ask us to make sure.
This MR study is for research purposes only and is not in any way a clinical scan to diagnose 
diseases for subjects.  The scans in this study are not designed for diagnosis.  The primary 
investigator, the lab, the MR technologist, and the Magnetic Resonance Research Center are 
not qualified to interpret the MR scans and cannot give subjects or their doctor a diagnostic 
evaluation of the images.  If we see something on their scan that might be medically 
significant, we will ask a radiologist or another physician to review the relevant images.  If 
that person recommends that the subject should seek medical advice, then the primary 
investigator or consulting physician will contact the subject, talk with them about the 
situation, and recommend that they seek medical advice as a precautionary measure.  At that 
point, the decision to seek advice or treatment is completely up to the subject and their 
doctor.  If the subject’s doctor wants to pursue additional MR images, the research scans 
from this study will not be available, and new scans that are appropriate for medical 
diagnosis will need to be done.  The researchers for this project, the consulting physician, the 
Magnetic Resonance Research Center, and Yale University are not responsible for any exam 
or treatment that the subject receives based on these findings.
Risks associated with the physiological recordings of respiration, heart rate, swallowing and 
galvanic skin response in the MRI environment.:
There are no known risks associated with these recordings. However, should the subjects 
feel anxious or uncomfortable with the any aspect of the recordings we will simply acquire 
the fMRI scan without them.
Risks-associated with the BodPod measurement:
There are no known risks associated with the BodPod measurement. However, some people 
may feel uncomfortable or anxious in the enclosed chamber of the BodPod. After each of the 
three 50-second measurements the experimenter will open the door. The experimenter can 
see the subject at all times in the BodPod and will show you the alarm button inside the 
BodPod that will interrupt the measurement if they feel anxious.

Risks involved with consumption of stimuli:
There are no known risks associated with consumption of any of the odors or liquids that 
subjects will encounter.  All are commercially available products that subjects will have 
likely encountered before.  Subjects with food allergies or sensitivities (for example nuts, 
lactose, artificial sweeteners) will be excluded.  
Risks involved with blood draws:
Potential risks associated with blood sampling include infection from failure to observe proper 
sterile conditions, and hematoma from careless technique. The latter may be associated with 
some discomfort, but presents very little danger to the subject’s welfare. In any case, a skilled 
phlebotomist will perform all blood draws.
Risks involved with pregnancy:
MR scans, and a restricted diet could be damaging for a developing fetus. Therefore, 
pregnant women will be excluded.
Risks for toxicology screenings:
Breath screening and urine collections are performed primarily as safeguards to 
contamination of data and should add no risks other than those normally associated with 
these procedures.
Risks for saliva sample collection and genotyping:
There is a slight risk of genetic information being used in inappropriate ways (e.g. to deny 
health insurance due to genotype).
10. Minimizing Risks: Describe the manner in which the above-mentioned risks will be 
minimized.
All researchers and research assistants involved in the study have taken the Human 
Investigations Training Course either on-line (through the NIH) or in person through the 
Yale University School of Medicine. All clinical procedures are performed the John B Pierce 
Laboratory by trained medical and scientific staff. Subjects may become anxious or fatigued 
during any of the procedures. They will be informed at the outset of the study that, should 
they experience undue anxiety or discomfort from the procedures, they are free to terminate 
the study at any time. Trained staff members will be working with the subjects throughout 
the study and will take appropriate steps to minimize anxiety and fatigue. We will attempt to 
minimize any discomfort associated with the procedures by informing the subject about what 
to expect prior to participation. Participants will be told that they are free to not respond or to 
terminate involvement at any time with no adverse consequences. All lab assessors are 
extensively trained on how to conduct assessments. Dr. Geha will also closely supervise all 
assessors.

Minimizing risk involved with administration of one oral dose of Morphine and Naltrexone
We will minimize the acute risk of administration of oral 30 mg Morphine or 50 mg of 
Naltrexone by carefully monitoring vital signs and mental status using neuro-checks every 60 
minutes after the administration. In addition, the study physician Dr. Paul Geha will always 
be present during the whole duration of the visit when either of these drugs is administered.
Minimizing risk involved with the questionnaires:
Should a subject meet diagnostic criteria for any psychiatric disorder Dr. Geha will refer 
them for treatment. If a participant appears to be distressed or fatigued during assessments, 
the assessor will halt the procedure and take a break. The session will only recommence 
when and if the participant reports feeling capable of continuing
Minimizing risks involved with the mock fMRI scanner
We will attempt to minimize any discomfort associated with the mock fMRI scanner by 
informing the subject about what to expect prior to participation and explaining to them the 
equipment, how it works, which parts are replaced for every subject and how we clean any 
components that are not. Subjects will be instructed to tell the experimenter if they feel any 
discomfort with the procedure so that the session can be terminated.
Minimizing risks involved with MRI
During the fMRI scans, the participants will be monitored for anxiety or related concerns by 
research personnel associated with the project. Participants and investigators will be 
screened for metallic objects prior to entering the scan room. Prior to inclusion in the study, 
the presence of potential MRI risks, such as pacemakers, surgical clips, or metallic devices 
will be excluded by medical and surgical history administered during screening. All subjects 
will wear foam earplugs and sound-reducing headphones to reduce risk of hearing damage 
due to the loud noise of the scanner. The minor risk of discomfort due to lying still for 60 
minutes will be minimized by providing custom pads and pillows designed to make the 
participants as comfortable as possible. Participants will communicate with the MR 
technologist and research assistant via an intercom system and may trigger and audible 
alarm at any time to stop the MRI session if he or she is uncomfortable or anxious. In 
addition, all imaging center staff, students, post-docs and research assistants will participate 
in safety training annually. Finally, all subjects are familiarized with MR procedures during 
the training session in the mock scanner to ensure that subjects that are schedule for the MR 
scan are comfortable with the procedures.
Minimizing risks related to pregnancy
To minimize risks related to pregnancy, we inform the subject that if they should become 
pregnant, they should report this to their health care professional, physician and to us 
immediately. If this happens during the study, the subject will stop his/her participation. We 
perform pregnancy tests along with toxicology tests during each assessment and intake.

Minimizing risks associated with the BodPod
The experimenter can see the subject at all times in the BodPod and will show them the 
alarm button inside the BodPod that will interrupt the measurement if they feel anxious.
Minimizing risks for toxicology screenings:
Every subject will use a new separately wrapped mouthpiece that will be attached to the 
breathalyzer. Bottles containing subject's urine specimens will be not be labeled and will be 
appropriately discarded in a biohazard container after instant testing. This information is not 
recorded.
Minimizing risks for saliva sample collection and genotyping:
No protected health information (PHI) will be kept with the DNA samples. Only authorized 
staff will have access to the password protected file that links name and ID number on a 
secure server.  Identifying data will be destroyed after 7 years. Genetic information will also 
not be disclosed to participants, physicians in order to maintain confidentiality and limit the 
possible misuse of genetic information. 
11. Data and Safety Monitoring Plan: Include an appropriate Data and Safety Monitoring Plan 
(DSMP) based on the investigator’s risk assessment stated below. (Note: the HIC will make 
the final determination of the risk to subjects.) For more information, see the Instructions, 
page 24.

participating in this study? 
The  investigator’s assessment of the overall risk for subjects participating in this 
study is moderate.

1. Personnel responsible for the safety review and its frequency:
The principal investigator, Dr. Paul Geha,  will be responsible for monitoring the data, assuring 
protocol compliance, and conducting the safety reviews at the specified frequency, which must 
be conducted at a minimum of every 6 months (including when reapproval of the protocol is 
sought).  During the review process, the principal investigator (monitor) will evaluate whether 
the study should continue unchanged, require modification/amendment, or close to enrollment. 
Either the principal investigator, or the IRB have the authority to stop or suspend the study or 
require modifications.
The risks associated with the current study are deemed greater than minimal for the 
following reasons: (choose those that apply)
1. We do not view the risks associated with morphine or naltrexone as minimal risk.
2. We do not view the risks associated with the combined use of morphine or naltrexone 
and fMRI as minimal risks.
3. Given the now established safety and validity of the current _________ in our prior work, 
we do not view the proposed studies as high risk.
4. Given our experience with the combined co-administration_________, we do not view 
the proposed studies as high risk.
Although we have assessed the proposed study as one of greater moderate risk, the potential 
exists for anticipated and/or unanticipated adverse events, serious or otherwise, to occur since it 
is not possible to predict with certainty the absolute risk in any given individual or in advance of 
first-hand experience with the proposed study methods. Therefore, we provide a plan for 
monitoring the data and safety of the proposed study as follows:
3. Attribution of Adverse Events:
Adverse events will be monitored for each subject participating in the study and attributed to the 
study procedures / design by the principal investigator, Dr. Paul Geha,  according to the 
following categories:
a.) Definite: Adverse event is clearly related to investigational procedures(s)/agent(s).
b.) Probable: Adverse event is likely related to investigational procedures(s)/agent(s).
c.) Possible: Adverse event may be related to investigational procedures(s)/agent(s).
d.) Unlikely: Adverse event is likely not to be related to the investigational 
procedures(s)/agent(s).
e.) Unrelated: Adverse event is clearly not related to investigational procedures(s)/agent(s).
4. Plan for Grading Adverse Events:
The following scale will be used in grading the severity of adverse events noted during the study:
1. Mild adverse event
2. Moderate adverse event

Page 28 of 52
3. Severe 
5. Plan for Determining Seriousness of Adverse Events:
Serious Adverse Events:
In addition to grading the adverse event, the PI will determine whether the adverse event meets 
the criteria for a Serious Adverse Event (SAE).  An adverse event is considered serious if it 
results in any of the following outcomes:
1. Death;
2. A life-threatening experience in-patient hospitalization or prolongation of existing 
hospitalization; 
3. A persistent or significant disability or incapacity; 
4. A congenital anomaly or birth defect; OR
5. Any other adverse event that, 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. 
An adverse event may be graded as severe but still not meet the criteria for a Serious Adverse 
Event.  Similarly, an adverse event may be graded as moderate but still meet the criteria for an 
SAE.  It is important for the PI to consider the grade of the event as well as its “seriousness” 
when determining whether reporting to the IRB is necessary.
Plan for reporting UPIRSOs (including Adverse Events) to the IRB
The principal investigator will report the following types of events to the IRB: 
Any incident, experience or outcome that meets ALL 3 of the following criteria:
1. Is unexpected (in terms of nature, specificity, severity, or frequency) given (a) the 
research procedures described in the protocol-related documents, such as the IRB-
approved protocol and informed consent document and (b) the characteristics of the 
subject population being studied; AND 
2. Is related or possibly related to participation in the research (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); AND
3. Suggests that the research places subjects or others at greater risk of harm (including 
physical, psychological, economic, legal, or social harm) than was previously known 
or recognized.
Unanticipated Problems Involving Risks to Subjects or Others (UPIRSOs) may be medical or 
non-medical in nature, and include – but are not limited to – serious, unexpected, and related 
adverse events and unanticipated adverse device effects.  Please note that adverse events are 
reportable to the IRB as UPIRSOs only if they meet all 3 criteria listed above.
These UPIRSOs/SAEs will be reported to the IRB in accordance with IRB Policy 710, using the 
appropriate forms found on the website. All related events involving risk but not meeting the

Page 29 of 52
prompt reporting requirements described in IRB Policy 710 should be reported to the IRB in 
summary form at the time of continuing review. If appropriate, such summary may be a simple 
brief statement that events have occurred at the expected frequency and level of severity as 
previously documented.  In lieu of a summary of external events, a current DSMB report can be 
submitted for research studies that are subject to oversight by a DSMB (or other monitoring 
entity that is monitoring the study on behalf of an industry sponsor).
7. Plan for reporting adverse events to co-investigators on the study, as appropriate the 
protocol’s research monitor(s), e.g., industrial sponsor, Yale Cancer Center Data and 
Safety Monitoring Committee (DSMC), Protocol Review Committee (PRC), DSMBs, study 
sponsors, funding and regulatory agencies, and regulatory and decision-making bodies.
For the current study, the following individuals, funding, and/or regulatory agencies will be 
notified (choose those that apply):
□ All Co-Investigators listed on the protocol.
□ National Institutes of Health
The principal investigator , Dr. Paul Geha, will conduct a review of all adverse events upon 
completion of every study subject. The principal investigator will evaluate the frequency and 
severity of the adverse events and determine if modifications to the protocol or consent form are 
required.
12. Statistical Considerations: Describe the statistical analyses that support the study design. 
fMRI Data Analysis: The following measures will be derived from brain data: (1) parameter 
estimates(PE) for milkshake (MS) minus Tls (tasteless) (MS-Tls) will be defined at the 
single subject level using general linear model (GLM), implemented in FSL toolbox55;whole 
brain connectivity of Blood Oxygen Level Dependent (BOLD) signal, using both MS runs or 
resting state runs, will be calculated between each voxel, or region of interest (ROI), and 
every other voxel in the brain to obtain (2) functional connectivity FC of specific ROIs  or  
(3) degree maps (DM).  FC is a measure of the strength of connectivity between an ROI and 
the rest of the brain; degree D is calculated as the total number of connections above a 
specific correlation threshold between a voxel and all the other voxels in the brain; we will 
study D over a range of thresholds 0.25 < r <0.65 56.  DM identifies brain hubs (with high D) 
and therefore allows between groups comparison in the most densely connected areas 57,58.
The design is a within subject repeated measures design with treatment  (Morphine, 
Naltrexone and Placebo) being the repeated measure and groups (healthy control vs. pain 
patients) as a factor.  We will use repeated measures ANOVA to find differences in brain 
response (i.e. (MS-Tls) or D or FC) and psychophysical ratings of milkshake. The repeated 
measures design is a powerful one because it does not suffer from between subject

variability.  According to the preliminary data we expect to see decreased response to MS in 
opiate treated back pain patients and decreased D and FC.

US59,60.  The starting dose is typically 10 to 30 mg every 4 hours as needed.  Patients with 
prior opioid exposure may require higher initial doses. For the purpose of the current 
proposal we will administer only one dose of 30 mg morphine. Therefore, the risks 
associated with chronic use of morphine are largely minimized by our protocol.  Oral 
Morphine has a wide margin of safety at 2-3 times of the “effective dose”. In addition, there is 
no evidence of long-term toxicity associated with the intake of one dose of Morphine. Several 
human imaging studies safely administered acute61-72 or chronic 73 opiate medications, 
including oral morphine, via the oral or the parenteral route.  Morphine side effects are dose

regarding hepatotoxicity, although these reversible effects tend to be associated with much 
higher doses than those used in routine clinical practice (e.g., 300 mg/day or more) and tend to 
occur only after a patient is on these high doses for extended periods.  For the purpose of our 
current protocol we will use one 50 mg dose one time only. In addition, there is no evidence of 
long-term toxicity associated with the intake of one dose of Naltrexone.  Naltrexone side effects 
occurring at > 10% rate are reported for combined oral and injectable form; however, as 
mentioned above oral Naltrexone has a low risk of side effects.

old). Flyers and business cards will be posted around Yale University (see attached research 
flyers), and advertisements will be posted in local newspapers or on local websites like 
Craig’s List, the Yale University Bulletin, and websites for social networking, like the “Yalies 
in New Haven” group on Facebook (see same wording as the flyers). Interested subjects will 
contact the research coordinators at a telephone number indicated on the flyer.  During the 
initial telephone conversation, she will provide a brief description of the study, schedule the 
subject's first session, and screen the subject to ensure that they meet inclusion criteria and do 
not possess any of the exclusion criteria. We request that written informed consent and 
HIPAA authorization be waived for this part of the screening (see below).  Written informed 
consent will be obtained immediately before the first session at The John B Pierce Laboratory.

i. Describe why it would be impracticable to obtain the subject’s authorization for 
use/disclosure of this data;
Since we perform our screenings over the phone, it is impractical to obtain a written 
HIPAA authorization. However, once eligibility is determined and the subject is willing to 
participate, the first session will be scheduled. At the beginning of this first session we will 
obtain Compound Consent and HIPAA Research Authorization for further use of the data.
b.
i. If requesting a waiver of signed authorization, describe why it would be 
impracticable to obtain the subject’s signed authorization for use/disclosure of this 
data;
Since we perform our part of our screenings over the phone, it is impractical to obtain a 
written HIPAA authorization. Prior to obtaining consent, all participants will be screened 
on the phone by the research coordinator. During this phone conversation, the research 
coordinator will provide a brief description of the study, including information about the 
tasks the subject will have to perform, where the study is conducted, how long the entire 
study participation will take, and the amount of financial compensation. Subjects will then 
be asked to verbally consent to us asking them various questions to ensure that they meet 
inclusion criteria and do not possess any of the exclusion criteria. We will use the 
following language during our phone screening: “We will keep the information we just 
talked about in our files until you come in to the first session of the study. If you qualify 
and choose to be part of the study, this information will become part of your study file. If 
you don't come in or if you don't qualify for the study, we will keep this information until 
the study is over and then we will destroy it. We are required by law to keep this 
information confidential and we will not use it for any purpose other than to see if you 
qualify for this study and for research oversight.” If the subject is eligible and willing to 
participate, the first session will be scheduled. At the beginning of this first session we will 
obtain Compound Consent and HIPAA Research Authorization.
By signing this protocol application, the investigator assures that the protected 
health information for which a Waiver of Authorization has been requested will not 
be reused or disclosed to any person or entity other than those listed in this 
application, except as required by law, for authorized oversight of this research 
study, or as specifically approved for use in another study by an IRB.
Researchers are reminded that unauthorized disclosures of PHI to individuals outside of the Yale 
HIPAA-Covered entity must be accounted for in the “accounting for disclosures log”, by subject 
name, purpose, date, recipients, and a description of information provided.  Logs are to be 
forwarded to the Deputy HIPAA Privacy Officer.
7. Required HIPAA Authorization: If the research involves the creation, use or disclosure of 
protected health information (PHI), separate subject authorization is required under the 
HIPAA Privacy Rule. Indicate which of the following forms are being provided:

8. Consent Personnel: List the names of all members of the research team who will be obtaining 
consent/assent. 
Paul Geha, Dana Small, Gelsina Stanley, Roberta Delvy, Elizabeth Garcia
9. Process of Consent/Assent: Describe the setting and conditions under which consent/assent will 
be obtained, including parental permission or surrogate permission and the steps taken to ensure 
subjects’ independent decision-making. 
Prior to obtaining consent, all participants will be screened on the phone by the research 
coordinator at The John B Pierce Laboratory. During this conversation, the research coordinator 
will provide a brief description of the study, including information about tasks the subject will 
have to perform in the behavioral assessments, where the study is conducted, the medications used, 
the risks and benefits of paricipation, how long the entire study participation will take, and the 
amount of financial compensation. Subjects will also be screened to ensure that they meet 
inclusion criteria and do not possess any of the exclusion criteria. If the subject is eligible and 
willing to participate, the first session will be scheduled. Informed consent will be obtained 
immediately at the beginning of the first session. Personnel obtaining consent have a thorough 
understanding of the methodology of the protocol and a comprehensive knowledge of the 
procedures of the protocol and are capable of answering the possible questions raised by the 
potential subject regarding the study. A subject will sit down at a desk in a room. The study 
personnel will ask the subject to read through the entire compound research authorization and 
consent form. After the subject had read the entire form the researcher will verbally summarize the 
procedure, risks and steps taken to minimize risks. The subject is explicitly asked if they have any 
questions. All questions will be answered, except in the rare case that providing full disclosure 
may influence the outcome of the study (e.g. we do not want subjects to be aware that the puddings 
are manipulated in fat content). In these circumstances, the experimenter will explain that this is 
the case and offer to provide a fuller answer after the experiment. Subjects will receive additional 
details about the assessments they are to perform and will be informed that they may withdraw 
from the study at any time with no penalty. Subjects will be asked if they understand what the 
study entails and if they have had sufficient opportunity to consider whether or not to participate. If 
a subject affirms she/he will then be asked to sign the compound consent form and research 
authorization form and given a copy (attached).
10. Evaluation of Subject(s) Capacity to Provide Informed Consent/Assent: Indicate how the 
personnel obtaining consent will assess the potential subject’s ability and capacity to consent to the 
research being proposed. 
This research does not involve subjects with limited decision-making capacity. We will not recruit 
vulnerable subjects. For this reason we do not anticipate recruiting subjects without the ability and 
capacity to consent. However, we will ask subjects if they understand what the study entails and if 
they have had sufficient information and opportunity to consider whether or not to participate.

11. Documentation of Consent/Assent: Specify the documents that will be used during the 
consent/assent process. Copies of all documents should be appended to the protocol, in the same 
format that they will be given to subjects. 
Adult compound consent and research authorization forms are attached. 
12. Non-English Speaking Subjects: Explain provisions in place to ensure comprehension for 
research involving non-English speaking subjects. If enrollment of these subjects is anticipated, 
translated copies of all consent materials must be submitted for approval prior to use. 
Our research does not involve non-English-speaking subjects.
12(a) As a limited alternative to the above requirement, will you use the short form* for 
consenting process if you unexpectedly encounter a non-English speaking individual interested 
in study participation and the translation of the long form is not possible prior to intended 
enrollment? 
YES ☐  NO ☐
Note* If more than 2 study participants are enrolled using a short form translated into the same 
language, then the full consent form should be translated into that language for use the next time 
a subject speaking that language is to be enrolled.
Several translated short form templates are found on our website at: 
 http://www.yale.edu/hrpp/forms-templates/biomedical.html. If the translation of the short form 
is not available on our website, then the translated short form needs to be submitted to the IRB 
office for approval via amendment prior to enrolling the subject. Please review the guidance and 
presentation on use of the short form available on the HRPP website.
If using a short form without a translated HIPAA Research Authorization Form, please 
request a HIPAA waiver in the section above. 
13. Consent Waiver: In certain circumstances, the HIC may grant a waiver of signed consent, or 
a full waiver of consent, depending on the study. If you will request either a waiver of consent,

 No
         If no, see http://hipaa.yale.edu/guidance/policy.html
 
 None of the portable devices contain PHI or HIPAA identifiers, and  they are password 
protected. The identifying data is stored on a password protected database on a secure 
server in The John B Pierce Laboratory. Thus identifiers are not kept on the same device 
as the study information.
d. What will be done with the data when the research is completed? Are there plans to destroy     
the identifiable data? If yes, describe how, by whom and when identifiers will be destroyed. 
If no, describe how the data and/or identifiers will be secured.
Identifying data are retained for a period of seven years after publication.
e.
Who will have access to the protected health information (such as the research sponsor, the  
investigator, the research staff, all research monitors, FDA, Yale Cancer Center Data and 
Safety Monitoring Committee (DSMC), SSC, etc.)? (please distinguish between PHI and de-
identified data) 
As NIH is funding the study, rules governing NIH access will apply. No other entities 
besides research staff and the investigator will have access to PHI or de-identified 
data, with the exception of presentations of data. These are typically reported as 
group averages. Where individual data are reported, individuals are not identified 
except by code.
g.   If appropriate, has a Certificate of Confidentiality been obtained? N/A
h.   Are any of the study procedures likely to yield information subject to mandatory reporting   
requirements? (e.g. HIV testing – reporting of communicable diseases; parent interview -
incidents of child abuse, elderly abuse, etc.). Please verify to whom such instances will need to 
be reported. N/A
SECTION IX: POTENTIAL BENEFITS
Potential Benefits: Identify any benefits that may be reasonably expected to result from the 
research, either to the subject(s) or to society at large. (Payment of subjects is not considered a 
benefit in this context of the risk benefit assessment.)

There are no direct benefits to participating subjects.  However, the study will help us understand 
the brain response to food in the presence and absence of opiate agonist/antagonists, which are 
highly prescribed nowadays for pain, addiction and obesity.  This understanding in turn will help 
us study the effect on body weight and behavior of prescription opiates in patients with pain.
         SECTION X: RESEARCH ALTERNATIVES AND ECONOMIC CONSIDERATIONS
1.     Alternatives: What other alternatives are available to the study subjects outside of the research?
The healthy participants for this study are not in need of treatment or seeking treatment. For this 
reason there is no alternative, except to decline participation in the study.
The pain participants might feel short-term relief of pain; If patients are interested in seeking 
such treatment they will be asked to talk to their doctor about it.
2. Payments for Participation (Economic Considerations): Describe any payments that 
will be made to subjects, the amount and schedule of payments, and the conditions for 
receiving this compensation. The subject’s payments for the open label and the randomized 
controlled study are the same per session completed. 
Remuneration is as follows for the randomized controlled study:

*  If the subject spends up to 15 minutes in the scanner but do not complete the study, they will 
instead be paid $50. If the subject spends more than 15 minutes, they will receive the full $100 
regardless of study completion.
Subjects will participate in one Intake Session ($80), 3 fMRI scanning sessions (with milkshake, 
each $100), and a completion bonus of $50, leading to a maximal remuneration of $430. In 
addition to this, they make variable earnings depending on their performance on one of the 
computer tasks. 
3.
Costs for Participation (Economic Considerations): Clearly describe the subject’s costs 
associated with participation in the research, and the interventions or procedures of the study that 
will be provided at no cost to subjects.    
There are no costs to the subject.
 
4.
In Case of Injury: This section is required for any research involving more than minimal risk.
a.     Will medical treatment be available if research-related injury occurs? 
b.     Where and from whom may treatment be obtained? 
c.     Are there any limits to the treatment being provided? 
d.     Who will pay for this treatment? 
e.     How will the medical treatment be accessed by subjects? 
If the subject is injured as a result of participation in this study, treatment will be provided. The 
subject or the subject’s insurance carrier will be expected to pay the costs of this treatment. No 
additional financial compensation for injury or lost wages is available.

COMPOUND AUTHORIZATION AND CONSENT FOR PARTICIPATION IN A 
RESEARCH PROJECT
200 FR. 1 (2016-2) 
YALE UNIVERSITY SCHOOL OF MEDICINE – YALE-NEW HAVEN HOSPITAL
Study Title: Brain effects of opiate agonist and antagonist-open label study
Principal Investigator: Paul Geha, MD
Funding Source: Yale University School of Medicine, Psychiatry Department
Invitation to Participate and Description of Project
Suggested Text:
You are invited to participate in a research study designed to look at the effect of 
morphine, on brain response to food. Morphine is a medication given to patients in severe pain; 
You have been asked to participate because you suffer from pain.  75 participants will be 
recruited for this study; 45 of them will have pain and 30 will not.
In order to decide whether or not you wish to be a part of this research study you should 
know enough about its risks and benefits to make an informed decision.  This consent form gives 
you detailed information about the research study, which a member of the research team will 
discuss with you.  This discussion should go over all aspects of this research: its purpose, the 
procedures that will be performed, any risks of the procedures, possible benefits and possible 
alternative treatments. Once you understand the study, you will be asked if you wish to 
participate; if so, you will be asked to sign this form.
Description of Procedures
You may be eligible for this study if you currently are healthy or have pain for more than 6 
weeks.  You must be in good physical health. You will be asked to come for 2 visits and will 
receive morphine on visit 2. 
Intake session
At an initial intake session of about 2.5 hours at The John B. Pierce Laboratory, you will be 
asked to complete some questionnaires and interviews, undergo body measures and provide a 
saliva sample to confirm your eligibility for this study. 
Blood sample
You will be asked not to eat or drink anything (except water) for 2 hours prior to the study start 
time. A licensed phlebotomist will obtain one sample of about 2 tablespoons of blood from a 
vein in your arm or hand.
Questionnaires, and Psychiatric assessments:

You will be asked to fill out questionnaires aimed at assessing for example your cigarette, 
alcohol or drug use, eating behaviors, physical activity level, dieting behaviors or personality. 
We will also conduct interviews assessing your current and past alcohol and illegal 
abuse/dependence, nicotine dependence, mood disorders, and alcohol and cigarette use.
Body measures
Body measures including body composition (BodPod measurement), height, weight, waist 
circumference, and hip circumference. You will be asked to participate in the BodPod 
measurement. The Bod Pod is a large self-contained testing chamber with a glass window that 
measures your body volume and uses it to calculate body composition. The assessment is simple, 
non-invasive, and takes only about 5 minutes. For the measurement to be accurate we ask that 
you do not eat, drink, or exercise for at least 2 hours before your session. Additionally, your 
clothing must be skin tight. We will provide spandex shorts and tops for this purpose (that are 
washed for every subject), or you can bring your own skintight sports or swimming clothing. 
Three consecutive 50-second measurements are taken during which the door of the chamber will 
be closed. You will hear sounds that indicate the pressure changes that are used to make the 
measurement. In between the measurements the experimenter opens the door. Some people may 
feel uncomfortable or anxious in the enclosed chamber of the BodPod. The experimenter can see 
you at all times in the BodPod and will show you the alarm button inside the BodPod that will 
interrupt the measurement in case you feel anxious. If your body measures do not match our 
inclusion criteria, you will be excluded from further participation.
Saliva sample
You will also be asked to provide a DNA sample by delivering some saliva in a cup. The 
purpose of collecting this sample is to understand the genetic factors that may influence your 
reactivity to tastes, odors, and food items.
Alcohol and Drug Screening
You are free to drink as usual during the study, except that we ask that you refrain from alcohol 
use the day before any assessment at The John B Pierce Laboratory. We will monitor your breath 
alcohol level by asking you to blow into a meter, called a breathalyzer, and also collect a urine 
sample to detect the presence of various drugs. 
If you are female: we do not wish to include females who are or may be pregnant. Therefore, all 
females of childbearing potential will be given a urine pregnancy test.  Results of the pregnancy 
test will be given to you only and will remain confidential. If the results indicate you are 
pregnant you will be excluded from the study. We also require that you are on a reliable form of 
birth-control throughout the remainder of the study
Your results from the blood sample and your responses to the questionnaires may exclude you 
from the study, however they will remain confidential. If you test positive for alcohol, drug use, 
or pregnancy the session will be cancelled and you will be excluded from further participation. 
We do not record the results of these tests.

fMRI mock scan training
At the JBP there is a mock MR-scanner, which does not contain the strong magnet found in a 
real MRI scanner, but instead is an identical replica of the real scanner. You will be asked to lie 
still on the MRI patient table and your head will be placed on a specially-designed holder. Your 
head will be cushioned by a firm foam pillow and you will be fitted with the mouthpiece.  You 
will receive different milkshakes through plastic beverage tubing attached to a mouthpiece on the 
head holder. The mouthpiece will be sterilized and new beverage tubing will be used for each 
subject. The mouthpiece will be positioned above your head so that the end rests comfortably on 
the tip of your tongue. The placement of the mouthpiece in your mouth will not interfere with 
breathing or swallowing. However, you may be asked to refrain from swallowing during certain 
parts of the experiment (never longer than 15 seconds). The table will then slide into the 
enclosed space of the mock MR scanner, which is a long tube. Some people become tired, 
uncomfortable or claustrophobic (uncomfortable in the small space) inside the mock MR 
scanner. You will be inside the mock MR scanner up to 30 minutes. The goal of the training 
session is to familiarize you with the procedure and make sure that you are comfortable with the 
mouthpiece, and swallowing small amounts of liquids while lying on your back. Also, if you are 
unable to hold your head very still or if you are uncomfortable inside the mock MR scanner, you 
may withdraw from the study or be asked to withdraw from the study (and still receive a pro-
rated payment for your participation).
Computer based decision-making games:
You will be asked to play computer-based games.  In one game you will be play with fake 
money.  In two other games you might end up earning additional bonus payment in real money. 
You will be presented with visual and auditory stimuli on a computer. In some trials you may be 
asked to make choices between the stimuli presented to you by pressing buttons on a keyboard or 
a response box. For example, you may be asked to choose between a certain winning of $5 or 
betting on winning $50 or losing $10. 
Baseline Assessment Session
Blood sample
You will be asked not to eat or drink anything after your last meal the night before (except water) 
your appointment, so we can assess your blood for naturally occurring chemicals that your body 
produces regularly as well as your blood glucose levels. A licensed phlebotomist will obtain one 
sample of about 2 tablespoons of blood from a vein in your arm or hand.
Body measures
As in body measures for the intake session above.
Computer tasks:
You will participate in 2 different computer tasks. During these tasks you will look at scales or 
words projected onto a computer screen. You will be asked to make ratings relative to these 
words or scales. This assessment will take about 30 minutes.

Questionnaires:
You will also be asked to fill out questionnaires aimed at assessing your cigarette, alcohol or 
drug use, inventory of bodily pain, eating behaviors, physical activity level, dieting behaviors, 
mood or personality.
Tasting session:
You will be asked to sample various food stimuli. You will also be asked to make ratings about 
your perceptions of these stimuli. For instance, you may be asked to judge the intensity, 
pleasantness or sweetness of the food. All stimuli are commercially available products, or made 
from commercially available products. You will sample these stimuli from cups. 
fMRI scan session
The fMRI session will take place at the MRRC (the Anlyan Building) at Yale University. 
Participation in the fMRI scan session(s) is dependent upon the fMRI training session(s). For 
example, it may be decided that you are not sufficiently comfortable in the enclosed environment 
of the MR simulator. During the actual scanning session you will spend a maximum of 90 
minutes inside the fMRI scanner. However, the whole session will take about 3 hour because we 
explain the procedure, collect ratings about your level of hunger and about your perception of the 
stimuli. It also takes time to get you set up in the scanner and to take you out of it. 
We will monitor your breath alcohol level by asking you to blow into a meter, called a 
breathalyzer, collect a urine sample to detect the presence of various drugs, and if you are a 
female perform a pregnancy test.  If you test positive for alcohol, drug use, or pregnancy the 
session will be cancelled and you will be excluded from further participation. We do not record 
the results of these tests.
Functional MRI is a type of brain scan that uses magnetic fields and radio waves to record 
changes in blood flow in your brain while you perform certain tasks.  
In order to make sure the MRI procedure will be safe, you will first be asked to fill out a 
screening form prior to participating in this study. It is important that you tell the experimenters 
in this study if you have any history of:
1. Metal fragments in your eyes or face.
2. Implantation of any electronic devices, such as (but not limited to) cardiac 
pacemakers, cardiac defibrillators, cochlear implants or nerve stimulators.
3. Surgery on the blood vessels of your brain.
4. Claustrophobia (fear of enclosed places).
To ensure that you bring no metal objects into the scanning room you will be asked to change 
into hospital scrubs in a private changing room. Your clothes and personal belongings will be 
brought with you to the scanner and will remain under the watch of study personnel at all times. 
You will be given instructions outside the MR scanner about the scanning. Next you will be 
asked to lie still on the MR patient table and your head will be placed on a specially-designed 
holder, enabling us to record the imaging signal. Your head will be cushioned by a firm foam

pillow. If applicable, the mouthpiece and or nasal mask will be placed into position. In addition 
we will place a few sensors to measure physiological signals in the scanner. To measure 
breathing we will wrap an elastic Velcro band around your chest, which will not interfere with 
breathing. We will also tape three sensors onto your thumb, index, and middle finger of your left 
hand to measure pulse and skin responses. We will also loosely tie expanding respiratory bellows 
around your thyroid cartilage to measure swallowing. This will not interfere with breathing or 
swallowing. However, if any of these sensors cause you discomfort we will remove them before 
proceeding with the scan. The table will then slide into the enclosed space of the MR scanner, 
which is a long tube. The MR scanner makes loud banging noises while making the fMRI 
pictures, so you will use ear plugs and/or specially designed headphones to reduce the noise. The 
experimenters will be able to talk with you through an intercom system to tell you how the study 
is going. The earplugs or headphones should not interfere with your ability to talk with the 
experimenters or your performance in the study. The stimuli (e.g. tastes) will then be delivered as 
described above (e.g. mouthpiece) while the MR scanner is running.
Some people become tired, uncomfortable or claustrophobic (uncomfortable in the small space) 
inside the MR scanner.  The information obtained from the MR scanner is only useful if you are 
able to complete the entire fMRI session and hold your head very still the entire time (up to 60 
minutes). Therefore please let the investigators know if you are uncomfortable in any way as 
soon as possible after the imaging session begins. 
The fMRI pictures obtained in this study will not be in a form readable by either you or your 
physician. Therefore we will not give you or your doctor a copy of the fMRI pictures or the 
results of your individual study. While a radiologist does not formally review the fMRI pictures 
in this study, if in the course of processing the images we notice any abnormality that would be 
potentially relevant to your health, we will tell you and a physician you designate.
On the same day after the fMRI scanning session we will proceed as described below; You will 
receive one dose of oral 30 mg Morphine 
Oral Morphine Session
First you will undergo an fMRI scanning session as described above.  Then, depending on the 
day you will be asked to take one oral dose of 30 mg Morphine.  First, your heart rate, 
respiratory rate, blood pressure, and oral temperature will be registered.  The doctor on the study 
will perform neurologic and brief mental exams on you. Next you will be given one dose of 30 
mg oral morphine with a cup of water and wait for 30 minutes. After 30 minutes have passed you 
will be asked to undergo another 30 minutes of scanning. During this time tastes will be 
delivered again. After the second scan you will be asked to stay for an additional 2 hours for 
monitoring. During this time your heart rate, respiratory rate, blood pressure, and oral 
temperature will be registered at least twice. The doctor on the study will perform neurologic and 
brief mental exams on you at least twice again to make sure you are not developing side effects 
from the medication.

A description of this clinical trial will be available on http://www.ClinicalTrials.gov, as required 
by U.S. Law. This Web site will not include information that can identify you. At most, the Web 
site will include a summary of the results. You can search this Web site at any time.
Risks and Inconveniences
Morphine 
Morphine is a medication used to ease severe pain. After one dose of morphine 30 mg you might 
feel the following: feeling sleepy, dizziness, dry mouth, upset stomach or throwing up, hard 
stools (constipation), headache, anxiety, feeling tired or weak, belly pain, muscle or joint  pain 
(including back pain) or sweating a lot.
However, because we are giving you one dose only   if these side effects occur they may last few 
hours only.
Even though it may be rare, some people may have very bad and sometimes deadly side effects 
when taking a drug. Signs of an allergic reaction, like rash; hives; itching; red, swollen, blistered, 
or peeling skin with or without fever; wheezing; tightness in the chest or throat; trouble breathing 
or talking; unusual hoarseness; or swelling of the mouth, face, lips, tongue, or throat, very bad 
dizziness or passing out, chest pain or pressure or a fast heartbeat, trouble breathing, slow 
breathing, or shallow breathing, noisy breathing, seizures, very hard stools (constipation), feeling 
very tired or weak, feeling very sleepy, mood changes.  
A very bad and sometimes deadly health problem called serotonin syndrome may happen if you 
take this drug with drugs for depression, migraines, or certain other drugs. Call your doctor right 
away if you have agitation; change in balance; confusion; hallucinations; fever; fast or abnormal 
heartbeat; flushing; muscle twitching or stiffness; seizures; shivering or shaking; sweating a lot; 
very bad diarrhea, upset stomach, or throwing up; or very bad headache.  Taking strong pain 
drugs like this drug may lead to a rare but very bad adrenal gland problem. Call your doctor right 
away if you have very bad dizziness or passing out, very bad upset stomach or throwing up, or if 
you feel less hungry, very tired, or very weak.
MRI
MRI is considered to be among the safest ways to examine the human body. They use 
magnetism and radio waves, not x-rays, to measure chemicals and take pictures of various parts 
of the body.  The United States Food and Drug Administration (FDA) has set guidelines for 
magnet strength and exposure to radio waves, and we carefully observe those guidelines. For 
your exposure in this study, no bad effects have been seen. This study has no painful parts. You 
will be watched closely throughout the study. Some people may feel uncomfortable or anxious 
during the MRI. If this happens to you, you may ask to stop the study at any time and we will 
take you out of the MR scanner. On rare occasions, some people might feel dizzy, get an upset 
stomach, have a metallic taste or feel tingling sensations or muscle twitches. These sensations 
usually go away quickly but please tell the research staff if you have them.

MRI poses some risks for certain people. If you have a pacemaker or some metal objects inside 
your body, you may not be in this study because the strong magnets in the MR scanner might 
harm you. Another risk is a metallic object flying through the air toward the magnet and hitting 
you. To reduce this risk we require that all people involved with the study remove all metal from 
their clothing and all metal objects from their pockets. Nothing metal can be brought into the 
magnet room at any time. Also, once you are in the magnet, the door to the room will be closed 
so that no one from outside accidentally goes near the magnet.
We want you to read the questions on the MR Safety Questionnaire and answer them very 
carefully.  Those questions are for your safety. Take a moment now to be sure that you have read 
the MR safety sheet and be sure to tell us any information you think might is important. Even if 
you think that it is probably okay, we would rather have you ask us to make sure.
This MR study is for research purposes only and is not in any way a clinical scan to diagnose 
diseases for you. The scans in this study are not designed for diagnosis. The primary investigator, 
the lab, the MR technologist, and the Magnetic Resonance Research Center are not qualified to 
interpret the MR scans and cannot give you or your doctor a diagnostic evaluation of the images. 
If we see something on your scan that might be medically significant, we will ask a radiologist or 
another physician to review the relevant images. If that person recommends that you should seek 
medical advice, then the primary investigator or consulting physician will contact you, talk with 
you about the situation, and recommend that you seek medical advice as a precautionary 
measure. At that point, the decision to seek advice or treatment is completely up to you and your 
doctor. If your doctor wants to pursue additional MR images, the research scans from this study 
will not be available, and new scans that are appropriate for medical diagnosis will need to be 
done. The researchers for this project, the consulting physician, the Magnetic Resonance 
Research Center, and Yale University are not responsible for any exam or treatment that you 
receive based on these findings. 
The various sensors that we use to measure physiological signals in the scanner will not interfere 
with breathing or swallowing and do not pose any anticipated risk. However, if any of these 
sensors cause you discomfort we will remove them before proceeding with the scan.
Pregnancy
MR scans could be damaging for a developing fetus. If you should become pregnant, you 
should report this to us, your health care professional and physician immediately. If you 
get pregnant during the study, you must stop the participation immediately. During the 
entire duration of this study you will need to have a reliable method of birth control, and 
we perform pregnancy tests for all female subjects along with toxicology tests during 
assessment and intake.
Alcohol and drug screening
You may be worried about hygiene and disclosing test results. For the breathalyzer we will use 
a clean, separately wrapped mouthpiece for each subject. Bottles containing urine specimens 
will be not be labeled and will be immediately discarded after testing. The results from these 
tests are not recorded.

Blood sample
Potential risks associated with blood sampling include infection from failure to observe proper 
sterile conditions, and hematoma from careless technique. The latter may be associated with some 
discomfort, but presents very little danger to your welfare. In any case, all blood draws will be 
performed by a skilled phlebotomist.
BodPod
There are no known risks associated with the BodPod measurement. However, some people may 
feel uncomfortable or anxious in the enclosed chamber of the BodPod. After each of the three 
50-second measurements the experimenter will open the door. The experimenter can see you at 
all times in the BodPod and will show you the alarm button inside the BodPod that will interrupt 
the measurement if you feel anxious.
Food samples
There are no known risks associated with drinking any of the liquids and beverages or eating any 
of the foods that are used in this research study. All are commercially available products.
Questionnaires, computer tasks, and other assessments
It is possible that the interviews may cause you distress or concern. For example, it may be 
distressing to disclose information about psychiatric difficulties in the structured interviews. It is 
also possible that you may become frustrated with some of the impulsivity or cognitive 
assessments. If you meet diagnostic criteria for any psychiatric disorder you will be referred for 
treatment. If you become distressed or fatigued during assessments, the assessor will halt the 
procedure and take a break. The session will only recommence when and if you feel capable of 
continuing.
Genotyping:
If you provided a saliva sample for genotyping, we will be getting personal information from 
you. There is always the possibility that someone who is not authorized might see it, though this 
has not happened previously. We take the following precautions to prevent any unauthorized 
persons from accessing to the information you give us:
Any information you give us will be kept strictly confidential. Participant information is 
maintained in locked files or computer files requiring a password and data are identified only by 
a code number/letter combination. Only the primary investigator and research staff and have 
access to these files. All research materials will be held in strictest confidence until the study is 
completed, at which point all identifying material will be destroyed. When the results of the 
research are published or discussed in conferences, no information will be included that would 
reveal your identity unless your specific consent for this activity is obtained. All DNA samples 
will be prepared, stored, and analyzed at The John B. Pierce Laboratory.  Then, the DNA 
samples will be analyzed in this lab using standard genotyping procedures. Identifying data will 
be kept on the password-protected server for a period of seven years. After seven years, the 
identifying data will be destroyed.

You may be worried about the potential risk for detection of any carriers of a disease or 
condition gene. However, we are not looking for disease or condition genes. We will only gather 
data about commonly occurring DNA variations. Consequently, a medical interpretation of your 
DNA sample cannot be made.
Under some circumstances, it can be a risk for genetic information to be known by the subject or 
others. Variation in some genes is known to be directly related to risk of certain illnesses. In 
some cases, knowledge of genetic information could have negative psychological consequences 
or could affect access to or retention of certain benefits or entitlements. For example, the 
information could potentially be used against you if it were revealed to insurance companies or 
potential employers. However, you will not get the results of the DNA portion of the study nor 
will the results be made available in your medical record. Additionally, we will take precautions 
to ensure that confidentiality is maintained and that genetic information is not unintentionally 
disclosed to inappropriate third parties. There is a federal law called the Genetic Information 
Nondiscrimination Act (GINA). In general, this law makes it illegal for health insurance 
companies, group health plans, and most employers, except those with less than 15 employees, to 
discriminate against you based on your genetic information. However, it does not protect you 
against discrimination by companies that sell life insurance, disability insurance, or long-term 
care insurance.
At any time you may withdraw your saliva or genetic information from the study by contacting 
the PI (contact information can be found on the last page of this form), after which we will 
destroy the biological material and any paper or digital records containing your genetic 
information
Benefits
Participation in this study may have direct benefits. If you have pain and receive morphine you 
might experience some short-term relief of your pain.
There are also benefits for the society at large. Obesity has now reached epidemic proportions in 
the United States. The increasing prevalence of obesity and its strong relation to a number of 
chronic conditions and cancer escalates the public health significance of this disease. Addiction 
to pain killers is very costly problems to patients and society.  Understanding how the brain 
reacts to them will clear the way to understanding long-term side effects such as dependence and 
obesity.
Economic Considerations
You will not have to pay for any of the procedures in which you participate as part of this 
research project. You will receive the morphine for free.

Treatment Alternatives/Alternatives
If you are selected because you are a healthy subject there is no alternative, except to decline 
participation in the study. If you are selected because you have pain you can seek pain treatment 
with your regular physician. Many behavioral (e.g. exercise, meditation) treatments as well non-
addiction inducing medications are available for pain. 
Confidentiality
Any identifiable information that is obtained in connection with this study will remain 
confidential and will be disclosed only with your permission.  Examples of information that we 
are legally required to disclose include abuse of a child or elderly person, or certain reportable 
diseases. When the results of the research are published or discussed in conferences, no 
information will be included that would reveal your identity unless your specific consent for this 
activity is obtained. 
We understand that information about you obtained in connection with your health is 
personal, and we are committed to protecting the privacy of that information.  If you decide to be 
in this study, the researcher will get information that identifies you and your personal health 
information.  This may include information that might directly identify you, such as your name, 
address, telephone number, e-mail address, and birthdate.  This information will be de-identified 
at the earliest reasonable time after we receive it, meaning we will replace your identifying 
information with a code that does not directly identify you. The principal investigator will keep a 
link that identifies you to your coded information, and this link will be kept secure and available 
only to the PI or selected members of the research team. Any information that can identify you 
will remain confidential. Participant information is maintained in locked files or in computer

researchers can use this Certificate to legally refuse to disclose information that may identify 
you in any federal, state, or local civil, criminal, administrative, legislative, or other 
proceedings, for example, if there is a court subpoena. The researchers will use the Certificate 
to resist any demands for information that would identify you, except as explained below.
The protection offered by the CoC does not stop us from voluntarily reporting information 
about suspected or known sexual, physical, or other abuse of a child or older person, or a 
participant’s threats of violence to self or others. If any member of the research team is given 
such information, he or she will make a report to the appropriate authorities. When the CoC is 
obtained, we will inform all active study participants.
