Brief summary:
The objective of this study is to evaluate the effectiveness of oral naltrexone tablets in pediatric and adolescent eating disorders, in particular anorexia nervosa and bulimia nervosa, as compared to placebo. Study participants will be patients in a partial hospitalization program or intensive outpatient program for eating disorder.

Detailed description:
Subjects participating in this study will receive routine care for eating disorder at a partial hospitalization (PHP) level of care at MSHMC. In PHP, all patients have weekly medical screening visits for the duration of their time in care, as well as weekly individual therapy sessions, individual dietician sessions, and psychiatry appointments. They have supervised meals and numerous group therapy sessions. Every three weeks, patients in PHP complete a battery of mood and eating disorder indices including those evaluated in this study; participants in this study will complete an additional two surveys with this routine battery. Participants in this study will have no alterations in their routine eating disorder care outside of study article use and these additional surveys.

Subjects will be enrolled at their first visit for eating disorder programming at child or adult partial hospitalization (PHP) programming at MSHMC adolescent medicine eating disorders clinic. Informed consent/assent will be obtained as described above.

The subject will be provided with oral naltrexone or placebo weekly from the MSHMC research pharmacy. Subjects will be given one weeks' worth of medication at a time. Subjects will be randomized at enrollment to receive either study drug (naltrexone) or placebo. Participants or parents of minor participants will be provided study drug or placebo following completion of urine drug screen and consent/assent. Patients will take the medication daily for six weeks. For subjects who are enrolled in child PHP and who eat meals with parents, the families may choose to administer study drug during meals at programming. For adult patients enrolled in adult programming, subjects may choose to self-administer the medication.

On their first contact with PHP, all patients in Child PHP complete various eating disorder indices as a part of routine care, including the ED-15, EDE-Q, RCMAS, CDI, GAD-7, and PHQ-9. This battery of indices is repeated every 3 weeks while a patient is in programming.

For those who are enrolled in this study, they will complete their routine indices, in addition they will also complete the BIS/BAS and the ABUSI at enrollment and at weeks 3, 6, and 9 (after completion of medication) while in programming. Participants will receive routine eating disorder care while in PHP.

Patients in Adult PHP typically complete a different inventory every three weeks. If a patient chooses to participate in this study they will be asked to complete the same surveys as participants in Child PHP, and they will receive the same amount and type of compensation.

Six months after enrollment, subjects will be sent copies of ED-15, EDE-Q, GAD-7, PHQ-9, BIS/BAS, and ABUSI indices either in an in-person medical appointment or via RedCap to complete. If the patient returns for medical follow-up between 5 and 7 months after enrollment, their height, weight, and body mass index will also be recorded to determine if weight restoration was maintained.

At initial contact with the eating disorders clinic, all patients receive an initial battery of laboratory tests as a part of the standard of care for eating disorder. These tests include liver function assays and transaminase levels.

Arms: arm 1: Oral naltrexone, to start as 25mg for three days then 50mg a day for 6 weeks. Oral naltrexone generic tabs will be blinded in opaque gelatin capsules with methylcellulose filler arm 2: Opaque gelatin capsules with methylcellulose filler, taken by mouth once a day for six weeks
Interventions: intervention 1: Naltrexone Hydrochloride intervention 2: Control
Intervention descriptions: intervention 1: 25mg x 3 days then 50mg a day thereafter intervention 2: Methylcellulose and gelatin capsule only

Study Objectives
Describe the purpose, specific aims or objectives.  State the hypotheses to be tested.
The objective of this study is to evaluate the effectiveness of oral naltrexone tablets in pediatric and 
adolescent eating disorders, in particular anorexia nervosa and bulimia nervosa, as compared to 
placebo. The hypothesis of this study is that patients receiving oral naltrexone will demonstrate greater 
improvement in their score on the ED-15, an evidence-based metric of eating disorder symptom severity 
and frequency1, than those receiving placebo, representing more complete recovery from eating 
disorder
1.2
Primary Study Endpoints
State the primary endpoints to be measured in the study.  
Clinical trials typically have a primary objective or endpoint. Additional objectives and endpoints are 
secondary.  The endpoints (or outcomes), determined for each study subject, are the quantitative 
measurements required by the objectives.  Measuring the selected endpoints is the goal of a trial 
(examples: response rate and survival).

The primary outcome will be clinically and statistically significant reduction in ED-15 score in those 
receiving medication vs placebo.
1.3
Secondary Study Endpoints
State the secondary endpoints to be measured in the study.
Secondary outcomes will include improvement in scores on Eating Disorder Examination Questionnaire 
(EDE-Q)2, the Patient Health Questionnaire-9 scale (PHQ-9,, a measure of depression)3 the Generalized 
Anxiety Disorder-7 scale(GAD-7, an inventory of anxiety)4, Alexian Brothers Urge to Self-Injure Scale

Background 
2.1
Scientific Background and Gaps
Describe the scientific background and gaps in current knowledge. 
For clinical research studies being conducted at Penn State Health/Penn State College of Medicine, and 
for other non-PSH locations as applicable, describe the treatment/procedure that is considered standard 
of care (i.e., indicate how patients would be treated in non-investigational setting); and if applicable, 
indicate if the treatment, drug, or device is available to patient without taking part in the study.
Oral naltrexone (Revia) is a long-acting opioid antagonist with approval from the Food and Drug 
Administration (FDA) for treatment of alcohol use disorder and provision of opioid receptor blockade7. It 
has demonstrated some utility in treating harmful, self-stimulatory behaviors (self-injurious behavior, 
SIB) in patients with autism (such as head-banging, self-mutilation, etc)8. It is generally well-tolerated, 
with few side effects outside of limiting the effectiveness of opioid medication7. Oral naltrexone became 
a therapeutic agent in the context of autism with SIB related to the “opioid hypothesis” of autism, 
namely, that the stereotyped behaviors of autism resembled those of addiction9,10. There are two 
proposed mechanisms of action for oral naltrexone in reducing self-harming behaviors: one, naltrexone 
disrupts serotonergic reward pathways that reinforce SIB11; and two, those with SIB have chronically 
elevated endogenous opioid production, where SIB increases endogenous opioid activity directly10.
There is some evidence of the value of treatment with naltrexone in bulimia12 and binge-eating disorder 
13,14, though intranasal naloxone, a related compound, has been shown to not be more efficacious than 
placebo in binge-eating disorder15. There is some evidence to suggest that naltrexone may be helpful in 
anorexia nervosa in adult patients16. A retrospective chart review of pediatric patients with bulimia did 
reveal subjective improvement in purging behaviors in patients taking oral naltrexone, however this 
study was retrospective, cross-sectional, unblinded, without a control group, and did not account for the 
effect of eating disorder therapy itself17. 
There is relatively little data regarding use of pharmacologic agents in anorexia nervosa, in particular in 
pediatric patients14,18.  The objective of this study is to evaluate the effectiveness of oral naltrexone 
tablets in pediatric and adolescent eating disorders, in particular anorexia nervosa and bulimia nervosa, 
as compared to placebo.

Previous Data
Describe any relevant preliminary data.

The investigators for this specific study do not have any of their own preliminary data. 
2.3
Study Rationale
Provide the scientific rationale for the research.
We hypothesize that oral naltrexone will provide additional treatment benefit for adolescents and 
young adults between age 13-25 who have compulsive behavior related to eating disorder, including 
bingeing, self-induced vomiting, compulsive exercise, or other inappropriate compensatory behaviors. 
We believe this because adult literature has demonstrated some efficacy of oral naltrexone in these 
areas, and pediatric autism literature has demonstrated safety in this age group.

We will identify potential subjects in the Adolescent Medicine and Eating Disorders Clinic at Milton S. 
Hershey Medical Center. Potentially eligible participants are adolescents and young adults coming to 
their initial medical assessment for eating disorder evaluation. Patients who elect to attend either the 
child or adult Partial Hospitalization Program for Eating Disorders (PHP) who are also medically 
appropriate for this level of care between ages 13-25 (inclusive) will be approached at their intake 
appointment for recruitment and consent.  
4.2
Recruitment process
Describe how potential subjects first learn about this research opportunity or indicate as not applicable 
if subjects will not be prospectively recruited to participant in the research.  Subject recruitment can 
involve various methods (e.g., approaching potential subjects in person, contacting potential subjects via 
email, letters, telephone, ResearchMatch, or advertising to a general public via flyers, websites, 
StudyFinder, newspaper, television, and radio etc.). DO NOT include the actual recruitment material or 
wording in this protocol.
[Do not type here]
4.2.1
How potential subjects will be recruited.
Potential subjects will be approached at their intake appointment or at initial psychiatry 
appointment for child or adult partial hospitalization program (PHP) for eating disorder, if this is the 
level of care they have elected to pursue. The study will be explained to them at that time and consent 
will be obtained, should the potential subject wish to enroll. As all participants in the study are also 
participating in a higher level of care for eating disorder through MSHMC, all participants are patients of 
either Dr Lane or Dr Essayli, who are both study team members. 
4.2.2
Where potential subjects will be recruited.
Potential subjects will be recruited in a private therapy or medical room at the Adolescent 
Medicine and Eating Disorders Clinic on the second floor of the Briarcrest building. 
4.2.3
When potential subjects will be recruited.
Potential subjects will be enrolled at one of two times: either at the initial medical screening 
appointment after the decision has been made for the patient to enroll in PHP, or at the initial 
psychiatry appointment following  initial medical appointment (that is, at actual enrollment in 
programming).
4.2.4
Describe the eligibility screening process and indicate whether the screening process will 
occur before or after obtaining informed consent. Screening begins when the investigator 
obtains information about or from a prospective participant in order to determine their 
eligibility.  In some studies, these procedures may not take place unless HIPAA Authorization 
is obtained OR a waiver of HIPAA Authorization when applicable for the screening procedures 
STUDY00014382
Approval: 8/23/2024


Page 10 of 45 (V.01/21/2019) 
is approved by the IRB.  [For FDA regulated studies, consent for any screening activities would 
need to be obtained prior to screening unless specifically waived by the IRB.]
When patients come into the clinic for either an initial medical screening appointment for 
their enrollment in PHP or in the initial psychiatry appointment that they have when they 
enroll, a staff member will assess the patient’s eligibility in participating in the research study 
using the information in the patient’s chart and information that is obtained in the 
appointment. The primary screening criterion will be that the potential subject choses to enroll. Potential 
subjects who are not medically appropriate for PHP or who do not desire to attend PHP will not be 
screened any further for the purposes of this study. The only screening that must take place is a point-of-
care pregnancy test for postmenarchal (having had at least one menstrual cycle) females with amenorrhea 
(absent or missed menses)—which is standard of care for these patients regardless of their decision to 
enroll or not—and a urine drug screen, as oral naltrexone may cause immediate opioid withdrawal if 
administered to a person with opioid-positive urine. Potential subjects with a positive urine pregnancy test 
or urine drug screen positive for opioids will not be enrolled. Urine drug screen and urine pregnancy test 
are specifically outlined in the study consent document.

should be discussed with subjects by the medical provider, as is standard of care for partial 
hospitalization programs for eating disorders. All inclusion and exclusion criteria should be 
reviewed by the medical provider to verify that the subject meets eligibility criteria prior to 
enrollment. Consent and assent will take place in a private, neutral environment with the 
patient and their parent, if the patient is under the age of 18.  The study coordinator, not the 
principal investigator or co-investigator, will enroll the participant in the study and answer all 
questions. Potential patients under the age of 18 will be asked to provide assent to participate 
in the study; if they do not wish to provide assent then their parents cannot provide consent on 
their behalf and therefore “force” the child to participate. Potential subjects who plan to enroll 
in PHP may do so regardless of their desire to participate in this study, which will be directly 
told to them in plain, spoken language at time of consent/assent and enrollment, as well as 
written in the consent form. The decision to participate or not to participate in this study 
should have no impact on the clinical care the potential subject receives while they complete 
PHP.

Waiver of Written Documentation of Consent 
Review “HRP – 411 – Checklist – Waiver of Written Documentation of Consent.” 
5.3.1
Indicate which of the following conditions applies to this research:
  The research presents no more that minimal risk of harm to subjects and involves no 
procedures for which written consent is normally required outside of the research context.
OR
  The only record linking the subject and the research would be the consent document and the 
principal risk would be potential harm resulting from a breach of confidentiality. Each subject 
will be asked whether the subject wants documentation linking the subject with the research, 
and the subject’s wishes will govern. (Note: This condition is not applicable for FDA-regulated 
research. If this category is chosen, include copies of a consent form and /or parental 
permission form for participants who want written documentation linking them to the 
research.)
OR
  If the subjects or legally authorized representatives are members of a distinct cultural group 
or community in which signing forms is not the norm, that the research presents no more 
than minimal risk of harm to subjects and provided there is an appropriate alternative

HIPAA Research Authorization and/or Waiver or Alteration of Authorization
This section is about the access, use or disclosure of Protected Health Information (PHI). PHI is individually 
identifiable health information (i.e., health information containing one or more 18 identifiers) that is transmitted 
or maintained in any form or medium by a Covered Entity or its Business Associate. A Covered Entity is a health 
plan, a health care clearinghouse or health care provider who transmits health information in electronic form.  
See “HRP-103 -Investigator Manual” for a list of the 18 identifiers.  
If requesting a waiver/alteration of HIPAA authorization, complete sections 6.2 and 6.3 in addition to section 
6.1. The Privacy Rule permits waivers (or alterations) of authorization if the research meets certain conditions. 
Include only information that will be accessed with the waiver/alteration.

Authorization and/or Waiver or Alteration of Authorization for the Uses and Disclosures of PHI
Check all that apply:
 
Not applicable, no identifiable protected health information (PHI) is accessed, used or 
disclosed in this study. [Mark all parts of sections 6.2 and 6.3 as not applicable]
Authorization will be obtained and documented as part of the consent process. [If this is the 
only box checked, mark sections 6.2 and 6.3 as not applicable]
Partial waiver is requested for recruitment purposes only (Check this box if patients’ medical 
records will be accessed to determine eligibility before consent/authorization has been

All data will be maintained in RedCAP, and will be accessible only to study 
members. A key linking study participants to study data will be kept for the 
duration that the study data are kept, and all research data will be retained 
per FDA regulation and institutional policy. Data maintained in PennState 
Health drives will be destroyed in accordance with current data management 
protocols at our institution and paper records will be securely shredded and 
incinerated. 
6.2.2
Explanation for why the research could not practicably be conducted without access to and 
use of PHI
Provide an explanation for why the research could not practicably be conducted without access 
to and use of PHI.
Much of the outcomes to be studied here, including weight restoration, length of time in care, 
or worsening of depression, are assessed on a regular basis as a part of routine clinical care. 
Because participants in this study will otherwise be undergoing routine care in PHP, access to 
PHI would reduce need for duplicate visits for study purposes only and should increase study 
retention. Additionally, certain inclusion and exclusion criteria, such as lab results, will be 
available in PHI and help determine participant eligibility.
6.2.3
Explanation for why the research could not practicably be conducted without the waiver or 
alteration of authorization
Provide an explanation for why the research could not practicably be conducted without the 
waiver or alternation of authorization.
Because participation in this study requires negative urine drug screen and normal bloodwork 
prior to enrollment, without being able to evaluate PHI prior to enrollment we will not be able 
to determine who is eligible without duplicating studies and potentially exposing the patient to 
excessive risk and pain in the form of duplicate lab studies and blood draws. 
6.3
Waiver or alteration of authorization statements of agreement
By submitting this study for review with a waiver of authorization, you agree to the following statement – 
DO NOT ALTER OR DELETE unless this section is not applicable because the research does not involve a 
waiver or alteration of authorization. If the section is not applicable, remove the statement and indicate 
as not applicable.
Protected health information obtained as part of this research will not be reused or disclosed to any 
other person or entity, except as required by law, for authorized oversight of the research study, or for 
other permitted uses and disclosures according to federal regulations. 
The research team will collect only information essential to the study and in accord with the ‘Minimum 
Necessary’ standard (information reasonably necessary to accomplish the objectives of the research) per 
federal regulations. 
Access to the information will be limited, to the greatest extent possible, within the research team. All 
disclosures or releases of identifiable information granted under this waiver will be accounted for and 
documented.

Note: Medical assessments may occur in weeks 1,3 etc or 2,4 etc depending on standard of care for that 
patient. As long as patients are seen within a 14 day interval (2 week timeframe), the exact week 
intervals (1,3 or 2,4) may vary. Additionally, the 6 month follow up appointment may take place any 
time between 5-7 months after study enrollment ends.

Study Procedures
Provide a step by step description of all research procedures being conducted (broken down by visit, if 
applicable) including such information as below (where and when applicable); describe the following:

HOW: (e.g., data collection via interviews, focus groups, forms such as surveys and questionnaires, 
medical/school records, audio/video/digital recordings, photographs, EKG procedures, MRI, mobile 
devices such as electronic tablets/cell phones, observations, collection of specimens, experimental 
drug/device testing, manipulation of behavior/use of deception, computer games, etc.)

WHERE: (e.g., classrooms, labs, internet/online, places of business, medical settings, public spaces, 
etc.)
Subjects participating in this study will receive routine care for eating disorder at a partial hospitalization 
(PHP) level of care at MSHMC. In PHP, all patients have biweekly medical screening visits for the 
duration of their time in care, as well as weekly individual therapy sessions, individual dietician sessions, 
and psychiatry appointments. They have supervised meals and numerous group therapy sessions. Every 
three weeks, patients in PHP complete a battery of mood and eating disorder indices including those 
evaluated in this study; participants in this study will complete an additional two surveys with this 
routine battery. Participants in this study will have no alterations in their routine eating disorder care 
outside of study article use and these additional surveys. 
Subjects will be enrolled at their first visit for eating disorder programming at child or adult partial 
hospitalization (PHP) programming at MSHMC adolescent medicine eating disorders clinic. Informed 
consent/assent will be obtained as described above.
The subject will be provided with oral naltrexone or placebo weekly from the MSHMC research 
pharmacy. Subjects will be given one weeks’ worth of medication at a time.  Subjects will be randomized 
at enrollment to receive either study drug (naltrexone) or placebo. Participants or parents of minor 
participants will be provided study drug or placebo following completion of urine drug screen and 
consent/assent. Patients will take the medication daily while they are in programming; after completion 
of programming or withdrawal from the study they will no longer be given study medication. For 
subjects who are enrolled in child PHP and who eat meals with parents, the families may choose to 
administer study drug during meals at programming. For adult patients enrolled in adult programming, 
subjects may choose to self-administer the medication.
On their first contact with PHP, all patients in Adult PHP complete various eating disorder indices as a 
part of routine care, including the ED-15, PHQ-9, GAD-7, and EDE-Q. This battery of indices is repeated 
every 3 weeks while a patient is in programming. 
For those who are enrolled in this study, they will complete their routine indices, in addition they will 
also complete the BIS/BAS and the ABUSI at enrollment and at weeks 1, 3, and 6 while enrolled in the 
study. Participants will also be asked to take the routine indices (ED-15, EDE-Q, PHQ, GAD, BIS/BAS, and 
ABUSI) at week 8 or 9 for a post-treatment evaluation. These will be taken in an in-person medical 
appointment or electronically via RedCap
STUDY00014382
Approval: 8/23/2024


Page 21 of 45 (V.01/21/2019) 
6 months after enrollment, subjects will be sent copies of ED-15, EDE-Q, PHQ, GAD, BIS/BAS, and ABUSI 
indices either in an in-person medical appointment or via RedCap to complete. If the patient returns for 
medical follow-up between 5 and 7 months after enrollment, their height, weight, and body mass index 
will also be recorded to determine if weight restoration was maintained.
Patients in Child PHP typically complete a different inventory every three weeks as part of routine care. 
If a patient choses to participate in this study they will be asked to complete the same surveys as 
participants in Adult PHP (ED-15, GAD-7, and PHQ-9), and they will receive the same amount and type of 
compensation as those who already take them as part of standard of care. 
REDCap, will be used to store the surveys. Participants will be sent the link to the battery of surveys via 
email at the designated times listed above. The link will redirect them to the programmed surveys in 
REDCap. Their responses will be stored in REDCap until data is exported and stored on the secure file 
server (hersheymed.net/files). Only authorized study personnel will have access to the REDCap surveys 
and folder access on the secure network. 
At initial contact with the eating disorders clinic, all patients receive an initial battery of laboratory tests 
as a part of the standard of care for eating disorder. These tests include liver function assays and 
transaminase levels. Further information about liver function test and monitoring for drug-induced liver 
injury is outlined in section 9.0. 
7.1.1
Enrollment. 
Provide a description of what procedures will be performed on visit 1 or day 1 or pre-test in 
order of how these will be done.  If your study only involves one session or visit, use this section 
only and indicate 7.2.2 as not applicable. 
As discussed above, patients can be enrolled at either their initial medical or initial psychiatric 
appointments for participation in the appropriate PHP for eating disorder.Per Joint Commission 
regulations of partial hospitalization programs for any psychiatric diagnosis, a complete blood count, 
blood chemistry, liver function test, urinalysis, and electrocardiogram must be obtained at enrollment 
and other studies at the program’s discretion. If all necessary bloodwork, EKG, and urine studies have 
been obtained within the last two weeks, these results will be tracked down, recorded into the medical 
record, and any necessary and routine studies that have not been completed prior to this appointment 
will be completed at enrollment. 
For patients enrolling at their medical appointment: after completion of the medical appointment, the 
study coordinator will approach the patient and family (if the patient is under 18 years of age), and 
discuss the study. The study coordinator will review the consent/assent forms, and after completion of 
the appointment the patient will be asked to obtain their routine studies (unless they have already been 
obtained as described above) within the coming seven days. A urine drug screen will be obtained at no 
cost to the participant and its results will not be placed into the medical record. Patients screening 
positive for any opioid will be excluded from the study and offered referral for addiction counseling. For 
potential female subjects, a serum pregnancy test will also be obtained at this time. Patients screening 
positive for pregnancy will be referred for options counseling
For patients enrolling at their psychiatric appointment: Joint Commission regulations regarding 
obtaining lab studies are unchanged, regardless of initial appointment location. All patients in PHP have 
biweekly medical appointments as a part of routine care, and routine enrollment labs are typically 
STUDY00014382
Approval: 8/23/2024


Page 22 of 45 (V.01/21/2019) 
obtained at the first medical appointment after first psychiatric appointment during the first seven days 
of programming. Labs will be ordered at that appointment and obtained within seven days, or entered 
into the medical record if obtained elsewhere, at that time. A urine drug screen will be obtained at no 
cost to the participant and its results will not be placed into the medical record. Patients screening 
positive for any opioid will be excluded from the study and offered referral for addiction counseling. For 
potential subjects who are female, a serum pregnancy test will also be obtained at this time. Patients 
with a positive pregnancy test will be referred for options counseling.
All participants, regardless of sex assigned at birth, gender, or menarchal status, will be required to use a 
highly reliable form of contraception should they be sexually active. Acceptable options have failure 
rates of less than 1% and include: combined hormonal contraceptives (such as oral contraceptive pills, 
patch, or vaginal ring), intrauterine device, depot-medroxyprogesterone injection, etonogesterel-
containing implants, and progestin-only contraceptive pills. Condoms, either internal or external, are not 
sufficient contraception if used alone. If a participant with a birth-assigned sex of female discloses coitus 
while participating in the study either without the use of contraception or with contraceptive failure 
(such as a broken condom with no second method of contraception), the participant will be offered a 
prescription for emergency contraceptive (ulipristal acetate or levonorgesterel 1.5mg) within 72 hours 
after coitus, pregnancy testing 14 days after the episode of coitus with referral according to results, and 
will be withdrawn from the study. 
7.1.2
Visit 2 or Day 2 or Post-test, etc. (If applicable) 
Provide a description of what procedures will be performed on visit 2 or day 2 or post-test in 
order of how these will be done.  If your study involves more than two sessions or visits 
replicate this section for each additional session or visit (e.g., 7.2.3, 7.2.4, etc.). 
On the first day of study participation after enrollment, all subjects will receive a complete set of 
vital signs (including heart rate, blood pressure, respiratory rate, temperature, and weight) and 
urine drug screen including screening for opioid substances prior to receipt of their first dose of 
study article. 
Routine care during PHP for any participant includes every-other-week in-person medical exams 
for the duration of the patient’s stay in program, as well as frequent appointments following 
completion of PHP, until discharge from clinic. At each medical appointment, patients receive a 
comprehensive physical exam including complete vital signs as above, and are routinely asked 
about mood changes, physical changes, difficulty or ease of adhering to routine program 
protocols, etc. All patients participating in PHP complete routine surveys to assess eating 
disorder recovery at intake and every three weeks until completion of program. For participants 
in this study, the documentation of their three- and six-week appointments will be reviewed for 
evidence of adverse effects related to study participation by study personnel. Participants will 
also complete two additional surveys, the ABUSI and BIS/BAS, beyond their routine PHP surveys 
at weeks three, six, and eight/nine. Routine medical testing will be obtained according to clinical 
need at all medical visits, regardless of participation in this study, for all patients participating in 
PHP.
For patients participating in this study, liver function panel will be obtained once every 3 weeks 
at no cost to study participants for the purpose of monitoring drug safety, as well as completion 
of all of the relevant study indices 
The vast majority of patients who require PHP have a routine medical follow-up at 
approximately six months; for those who do not this appointment will be made at no cost to the 
participant. At this appointment, participants will again undergo a comprehensive physical

Subjects will be enrolled in this study for a total of six months, starting at enrollment in PHP, and 
continuing to their final 6-month follow-up visit. They will have study interventions at 0, 3, and 6 weeks, 
and again at six months. They will take study medication while in PHP, and stop once six weeks of study 
duration is completed. Duration of PHP is individualized, but is on average about 8 weeks. Duration of 
PHP will not be dependent upon study participation.

Test Article(s) (Study Drug(s) and/or Study Device(s))
7.3.1
Description
Provide a brief description of all test articles (drugs (including any foods and dietary 
supplements), devices and/or biologics used in the research including the purpose of their use 
and their approval status with the Food and Drug Administration (FDA). Include information 
about the form of the drug product (e.g., tablets, capsules, liquid).
The Penn State Health IDS pharmacy will purchase Naltrexone 50mg tablets from a 
pharmaceutical wholesaler.  The IDS pharmacy will purchase gelatin capsules and USP grade 
methylcellulose from a pharmacy supplier to be used for compounding the active and placebo 
capsules.  For the active Naltrexone 50mg capsules, a Naltrexone 50mg tablet will be placed in 
an empty gelatin capsule with methylcellulose filler.  The placebo capsules will be empty gelatin 
capsules filled with Methylcellulose. 
The Food and Drug Administration has approved oral naltrexone for the treatment of alcohol 
use disorder and for blockade of opioid receptors7. This medication is not approved for the 
specific use of treatment of eating disorder, impulsive behavior, or self-injurious behavior. 
7.3.2
Treatment Regimen
Describe dose, route of administration and treatment duration. Include information about dose 
adjustments.
All subjects receiving study medication will receive oral naltrexone 50mg oral tablets, blinded as 
described above. All subjects receiving placebo will receive methylcellulose, blinded as 
described above. All capsules, regardless of contents, will be administered by mouth once daily, 
at a time of day to be chosen by the study participant.
In pediatric autism literature, doses between 0.5-2 mg/kg are described8,11,22,22–25, though in 
adult eating disorder literature doses of 50-100mg are described13,14,16–18. Food and Drug 
Administration labelling of oral naltrexone for treatment of alcohol use disorder and opioid 
receptor blockade describe an appropriate maintenance dose of 50mg per day7. Therefore 
subjects will receive 50mg of oral naltrexone a day if they are randomized to the medication 
group. Patients with body weight less than 25kg are excluded from the study so that no 
participant will exceed the maximum described pediatric dose of 2 mg/kg. Participants receiving 
STUDY00014382
Approval: 8/23/2024


Page 24 of 45 (V.01/21/2019) 
study article will receive 25mg of naltrexone for three days, followed by increase to study dose 
of 50mg/day The maximum daily dose is 50mg. 
Participants will take study medication daily while they are in PHP or for six weeks total. That is, 
if a participant is in PHP for three weeks, they will take the study medication for the entirety of 
their time in PHP and then continue to take the medication for three additional weeks after 
discharge from PHP. If a participant is in PHP for twelve weeks—which is quite uncommon—
they will only take study medication for six weeks. 
For participants who complete PHP early, they will be asked to complete the same battery of 
surveys at 3 and 6 weeks, at weeks 8/9 for post-treatment evaluation, and at 6 months. Survey 
responses will be obtained via RedCAP for participants not on-site at time of survey completion. 
Participants who, upon completion of the study, feel that they had significant benefit from the 
study article which lost upon withdrawal of the study article, are eligible for open label oral 
naltrexone therapy if desired. Participants will be asked at subsequent medical and behavioral 
health follow-up appointments if they felt they benefitted from the study article. If they feel 
they did, they will be offered a prescription for oral naltrexone to start at 25mg/day for three 
days and then 50mg a day after. 
7.3.3
Method for Assigning Subject to Treatment Groups
Describe the randomization process and how the associated treatment assignment will be 
made.
Subjects will be randomized at enrollment using RedCap. Randomization will be stratified by age 
(16 and under or 17 and older) and diagnosis (anorexia nervosa binge/purge subtype and 
bulimia nervosa or OSFED with bingeing or purging behaviors), equaling 4 strata.
7.3.4
Subject Compliance Monitoring
Insert the procedures for monitoring subject compliance.
Participants will receive one week of study intervention at a time, provided by Penn State 
Research Pharmacy. Medication will be delivered weekly to the Milton S. Hershey Medical 
Center Adolescent Medicine and Eating Disorders Clinic. At the time of delivery of a new week’s 
supply of medication, participants will return any unused medication for pill counts to 
determine adherence.
Additionally, participants in PHP are allowed to either self-administer medication or receive 
medication from their parents, if under 18 years of age. Participants will have the option to take 
medication on-site during programming, either as self-administration if over 18 years of age or 
from a parent if 17 years of age or younger, as they will be in clinic for about 8 hours a day, from 
their own supply. No study or clinic staff will handle medication. No study or clinic staff will 
administer medication. 
7.3.5
Blinding of the Test Article
Describe how the test article is blinded.

Participants will receive seven gelatin capsules at a time, packaged in 
conventional amber plastic medication bottles with child safety caps. These will 
be brought to the Milton S. Hershey Medical Center Adolescent Medicine and 
Eating Disorders Clinic weekly by Penn State Research Pharmacy staff and given 
to participants in that setting. At time of receipt of one week’s worth of study 
medication, any remaining medication from the previous week will be returned 
to the research pharmacy and disposed of by pharmacy staff according to 
guidelines. 
7.3.6.2
Storage
Describe the plans to store, handle the test article so they will be used only 
on subjects and only by authorized investigators. Describe storage 
temperature requirements and how temperature will be monitored and 
recorded.
As described above, test article will be dispensed to participants or 
participants’ parents/legal guardians in the MSHMC Adolescent Medicine 
and Eating Disorders Clinic. All participants in this study are also patients in 
PHP, therefore they all have patient identification bands while they are on-
side. Participant identity will be verified with ID bands, and their legal 
guardians will be identified by government-issued photo identification. 
Participants can self-administer test-article on site during PHP, or 
participants’ parents can administer the test article on site. While this is 
clearly optional and not feasible for all participants on all days—especially 
weekends—this method will be encouraged by study staff, though study 
and clinic staff will neither handle nor administer study medication.

the end of the study and whether the test article is to be shipped back to a 
source or destroyed on site.
Expired medications and medications returned by subjects unused will be 
documented and destroyed as per the IDS Destruction Policy.   At the end 
of the study, any remaining study medications will be documented and 
destroyed as per the IDS Destruction Policy.
7.3.6.5
Prior and Concomitant Therapy
Describe what prior and/or concomitant medical therapy will be collected. 
Describe which concomitant medicines/therapies are permitted during the 
study. Describe which concomitant medicines are not permitted during the 
study.
Many patients in PHP are on other medications, some of which are 
relevant to psychiatric diagnoses—such as selective serotonin reuptake 
inhibitors—and several are not, such as polyethylene glycol for 
constipation. Medication usage will be tracked during this study by 
following medication reconciliation performed at biweekly medical 
appointments while in PHP, which is the standard of care for patients 
requiring this level of care. 
Participants will be permitted any medication other than opioid 
medications. Any potential participant with a prescription for opioid 
medication, such as buprenorphine/naloxone combination strips or with a 
positive urine drug screen for opioids will be excluded. Any participant 
requiring opioid painkillers during this study will be dropped from the 
protocol. Patients will not be permitted to use medical cannabis during this 
study.

Subject Numbers and Statistical Plan
8.1
Number of Subjects
Indicate the maximum number of subjects to be accrued/enrolled. Distinguish between the number of 
subjects who are expected to be enrolled and screened, and the number of subjects needed to 
complete the research procedures if applicable (i.e., numbers of subjects excluding screen failures.)
Because this is a pilot study, we have decided a priori to enroll 30 participants in each arm of treatment 
for a total of sixty subjects. In 2019, approximately 150 patients meeting criteria for potential inclusion 
(between ages of 12-18, needing PHP level of care in the eating disorder clinic, no diagnosis of gender 
dysphoria or intellectual disability, with diagnoses of anorexia nervosa, or bulimia nervosa) were seen 
for initial evaluation in the eating disorder clinic. Therefore we hope to be able to enroll sixty 
participants over the course of 12 to 18 months. 
8.2
Sample size determination
If applicable, provide a justification of the sample size outlined in section 8.1 to include reflections on, or 
calculations of, the power of the study.
This is a pilot study, and enrollment size was determined a priori to allow for completion of enrollment 
within 18 months. 
8.3
Statistical methods
Describe the statistical methods (or non-statistical methods of analysis) that will be employed.
 
For analysis, data will be analyzed for differences between participants receiving naltrexone and 
participants receiving placebo. The data will be analyzed for demography differences between the two 
groups at baseline, and outcomes will be compared at three and six weeks; as well as at 6 months. 
Outcomes to be compared are stated in section 1.1 and 1.2. Within each group, these outcomes will also 
be compared across time. Statistically significant differences between each group at each endpoint will 
be noted and reported. 
9.0
Data and Safety Monitoring Plan
This section is required when research involves more than Minimal Risk to subjects as defined in “HRP-001 
SOP- Definitions.”
Minimal Risk is defined as the probability and magnitude of harm or discomfort anticipated in the research that 
are not greater in and of themselves than those ordinarily encountered in daily life or during the performance of 
routine physical or psychological examinations or tests.  For research involving prisoners, Minimal Risk is the 
probability and magnitude of physical or psychological harm that is normally encountered in the daily lives, or in 
the routine medical, dental, or psychological examination of healthy persons. 
Please complete the sections below if the research involves more than minimal risk to subjects, otherwise 
indicate each section as not applicable.

9.1
Periodic evaluation of data
Describe the plan to periodically evaluate the data collected regarding both harms and benefits to 
determine whether subjects remain safe.
This clinical trial will be monitored with the assistance of the Data Management Unit at Penn State 
Health College of Medicine. Once weekly, the principal investigator and members of the study team will 
review results of liver function screens, pregnancy tests, vital signs, and results of the Columbia Suicide 
Severity Rating Scale (C-SSRS, for participants age 18 and older ) or Ask Suicide Screening Questions 
(ASQ, for patients age 13 to 17)for all participants. Results of liver function tests, pregnancy tests, and 
vital signs will be recorded and tracked using a secured database.
It is expected that the total blood draw volume for this study will not exceed 16ml (for male 
participants) and 18ml (for female participants), using a volume of 4ml for measurement of hepatic 
function three times over nine weeks, and 1.5ml for serum pregnancy testing, with allowance for error 
in draw.
9.2
Data that are reviewed
Describe the data that are reviewed, including safety data, untoward events, and efficacy data.
Participants in this study will take the study article daily while they are enrolled in program. When they 
complete program, they will no longer be obliged to take the study article, nor will they be required to 
have weekly psychiatric evaluation, laboratory evaluation, or suicide assessments.  Patients in PHP have 
at least one medical follow-up appointment two weeks after they complete program, and further 
follow-up based on the patient’s needs.
During the course of the trial, we will monitor:

New diagnoses of depression, anxiety, suicidal thoughts, suicidal ideation, self-injurious 
behavior and related diagnoses via chart review. Monitoring for these new diagnoses is a part of 
routine care of PHP

The results of every-three-weeks liver function tests

The results of every-three-weeks urine pregnancy tests in female participants

Vital signs

The results of the behavioral health surveys

New diagnoses of abdominal pain, nausea, vomiting, headache, or fatigue regardless of 
relationship to diagnosis of eating disorder, though these are common problems in eating 
disorder treatment

New diagnoses of jaundice, liver failure, elevated transaminases, rash, or other medical 
problems that are uncommon in the treatment of eating disorder. 

New diagnosis of pregnancy

Length of participation in PHP, as patients who are experiencing good results with the study 
article may require a shortened length of stay in program

Need for escalation of eating disorder or mental health care, such as need for inpatient 
hospitalization for medical stabilization of eating disorder or other medical diagnosis, need for 
residential care for eating disorder, 

Incidence of death or serious bodily harm

Incidence of acute withdrawal from narcotic agents (expected to be zero due to pre-
participation urine drug screen, though this is a serious event)

9.3
Method of collection of safety information
Describe the method by which the safety information will be collected (e.g., with case report forms, at 
study visits, by telephone calls and with subjects).
 All patients participating in PHP receive biweekly medical visits, including comprehensive physical exam, 
vital signs, review of suicidal thoughts or behaviors, review of systems, and review of eating disorder 
symptom severity and frequency as a part of routine care in PHP. Patients also fill out the Columbia 
Suicide Severity Rating Scale (C-SSRS a metric assessing for the presence and severity of suicidality) or 
Ask Suicide Screening Questions (ASQ, a similar metric) once weekly while in care, with patients age 18 
and older using the C-SSRS and patients age 13-17 using the ASQ. Participants in this study will be no 
different, with the notable exception of every-three-week liver function and urine pregnancy tests 
(assigned female at birth patients only). 
Study participants’ charts will be reviewed weekly while they are in program by the PI and the study 
coordinator for any of the above-mentioned possible new diagnoses, lab results, C-SSRS results, as well 
as review of all routine care detailed above. Study staff who provide direct care to participants will alert 
the PI and the study coordinator of any adverse events encountered during the course of routine care. 
The results of all safety screenings will be kept in a comprehensive, secure database and will be 
reviewed weekly by the study team
9.4
Frequency of data collection
Describe the frequency of data collection, including when safety data collection starts.
Safety data collection will begin at enrollment, as vital signs, serum pregnancy tests, and urine drug 
screens will be collected at that time, continue through the first medical appointment after enrollment 
in the study, and will be subsequently obtained at weekly intervals thereafter.
9.5
Individuals reviewing the data
Identify the individuals who will review the data. The plan might include establishing a data and safety 
monitoring committee and a plan for reporting data monitoring committee findings to the IRB and the 
sponsor.
The PI and study coordinator will review the safety data at weekly intervals with the assistance of the 
Data Management Unit at Penn State College of Medicine. Any adverse events deemed to be the result 
of study participation and not the result of routine eating disorder care will be reported to the IRB as 
well as the study sponsor. 
9.6
Frequency of review of cumulative data
Describe the frequency or periodicity of review of cumulative data.
 The PI and study coordinator will review the safety data at weekly intervals with the assistance of the 
Data Management Unit at Penn State College of Medicine. Any adverse events deemed to be the result 
of study participation and not the result of routine eating disorder care will be reported to the IRB as 
well as the study sponsor.
9.7
Statistical tests
Describe the statistical tests for analyzing the safety data to determine whether harms are occurring.
No statistical tests for analyzing safety data are scheduled for this trial.

Suspension of research
Describe any conditions that trigger an immediate suspension of research.
  Monitoring for safety of the study article will be completed in accordance with Federal Food and Drug 
Administration requirements for surveillance of drug-induced liver injury (DILI), in accordance with Hy’s 
law. 
The study will be stopped early in the event of certain specific conditions that are more likely to be due 
to study intervention than to the disease itself. Several possible adverse effects of this medication can 
also be common features of eating disorder or eating disorder treatment itself, including worsening 
depression, self-injurious behavior, and suicide attempt 7,10,11,17,26–29. The following circumstances would 
trigger immediate suspension of this study with evaluation of safety data and profile:

Death of a study participant

Psychiatric hospitalization for suicidal ideation in any two study participants within a six month 
window

Two participants experiencing elevation of AST or ALT more than three times the upper limit of 
normal for age during the course of the study. 

AST or ALT levels elevated more than five times the upper limit of normal in any participant at 
any time. 

One participant with elevated serum total bilirubin to more than twice the upper limit of normal 
for age with evidence of pure hepatocellular injury (that is, no evidence of obstruction, 
malignancy, genetic disease, other medication effects, viral or bacterial infection) and AST or 
ALT elevation greater than three times the upper limit of normal for age. 

New diagnosis of liver failure of any participant

Any other serious medical or psychiatric condition felt to be potentially related to the study 
article. 
Any suspected case of drug-induced liver injury will be reported to the Food and Drug 
Administration using the specified information provided in the FDA’s document, Guidance for Industry 
Drug-Induced Liver Injury: Premarketing Clinical Evaluation. 
Should any participant demonstrate elevation of AST/ALT above the upper limit of normal for 
age, the study article will be discontinued. AST and ALT measures will be obtained twice weekly until 
they have normalized. More complete history will be obtained, specifically with respect to medications, 
supplements, recreational drug use history, travel, and chemical exposure. Participants with elevation of 
AST and ALT will also be evaluated for acute viral hepatitis types A, B, C, D, and E; autoimmune hepatitis, 
alcoholic hepatitis, non-alcoholic steatohepatitis, biliary tract disease, and hypoxic/ischemic 
hepatopathy. The liver’s function will be assessed directly via measurement of direct bilirubin and 
nternational normalised ratio (INR).

Risks
List the reasonably foreseeable risks, discomforts, hazards, or inconveniences to the subjects related the 
subjects’ participation in the research. Include as may be useful for the IRB’s consideration, a description of the 
probability, magnitude, duration and reversibility of the risks. Consider all types of risk including physical, 
psychological, social, legal, and economic risks.  Note: Loss of confidentiality is a potential risk when conducting 
human subject research.

If applicable, indicate which procedures may have risks to the subjects that are currently unforeseeable.

If applicable, indicate which procedures may have risks to an embryo or fetus should the subject be or 
become pregnant.

If applicable, describe risks to others who are not subjects.
In general, naltrexone is a well-tolerated medication, though we do plan to monitor for foreseeable risks. 
STUDY00014382
Approval: 8/23/2024


Page 31 of 45 (V.01/21/2019) 
Risks associated with taking oral naltrexone: 

elevated transaminases

depression and mood changes 

abdominal pain 

nausea

headache
Additional clinical risks that could be associated with taking Oral Naltrexone: 

Some pediatric autism literature describes low appetite or occasionally worsening of self-injurious 
behavior while on naltrexone8,11,22,22–25,27. There can also be worsening depression according to the FDA 
label7. These adverse effects are occasionally seen with PHP for eating disorder itself, and therefore we 
monitor for them frequently as a part of the standard of care. Should the subject or the subject’s parent 
wish to withdraw from the study due to these effects, they are free to do so. If these adverse effects are 
felt to be related more to the natural history of eating disorder and not to study intervention; or the 
severity is minor to moderate; the subject may continue to participate in the study if desired. If the 
effect is severe the subject will be withdrawn. 

Oral naltrexone is a pregnancy category C medication7, where there are animal studies that may indicate 
harm to the fetus but no specific human studies on this topic. For this reason, we will test for pregnancy 
in allbirth-assigned females at enrollment using a serum pregnancy screen, and every three weeks 
throughout the study using a urine pregnancy screen. . The majority of patients enrolled in child PHP 
have not yet had coitarche, though in adult PHP a history of sexual activity is more common. 
Other risks of participation include: 
•
Loss of confidentiality
•
Risk of randomization
•
Risk of incidental findings
Anxiety from completing questionnaires

Potential Benefits to Subjects and Others 
11.1
Potential Benefits to Subjects
Describe the potential benefits that individual subjects may experience from taking part in the research. 
If there is no direct benefit to subjects, indicate as such. Compensation is not considered a benefit. 
Compensation should be addressed in section 14.0.
There is potential direct benefit to participants, as the study intervention may improve eating disorder 
symptoms more rapidly than PHP alone. 
Participants receiving placebo are not expected to have direct benefit.
11.2
Potential Benefits to Others
Include benefits to society or others. 
Others may potentially benefit if oral naltrexone is shown to have some efficacy over PHP alone, as 
there are not many effective pharmacotherapies for eating disorder. If this medication is shown to have 
some beneficial effect in this study, the hope is that eating disorder may have another treatment option.

tests, genetic tests, or incidental findings) will be shared with subjects or others (e.g., the subject’s primary care 
physicians) and if so, describe how information will be shared. 
Any information collected as a part of standard of care will be shared with the participant and the participant’s 
primary care provider as it would have otherwise been shared with them during PHP, usually in weekly-to-
monthly letters to the primary care provider or via patient portal. This includes lab results and survey results. 
Any additional information obtained, such as ABUSI results or liver function tests at 6 weeks, may be shared in 
the same fashion.

Subject Payment and/or Travel Reimbursements
Describe the amount, type (cash, check, gift card, other) and timing of any subject payment or travel 
reimbursement. If there is no subject payment or travel reimbursement, indicate as not applicable. 
Extra or Course Credit:  Describe the amount of credit and the available alternatives. Alternatives should be 
equal in time and effort to the amount of course or extra credit offered. It is not acceptable to indicate that the 
amount of credit is to be determined or at the discretion of the instructor of the course. 
Approved Subject Pool: Indicate which approved subject pool will be used; include in response below that 
course credit will be given and alternatives will be offered as per the approved subject pool procedures. 
Participants will be given a $25 Greenphire Clincard at two timepoints during the study: enrollment, and at the 6 
month follow-up, for a total of $50 of reimbursement. Participants will receive the gift card shortly after their 
enrollment in the trial and after completing a 6 month follow up appointment. If the participant withdraws for 
any reason, they will only receive the $25 from enrollment.

Economic Burden to Subjects
14.1
Costs
Describe any costs that subjects may be responsible for because of participation in the research.
Participants are expected to incur minimal study-related costs. Any costs of routine care will be billed to 
their insurance providers as a part of routine care or care administered during PHP. Any costs of study-
specific care, such as test article or specific laboratory evaluations, shall be covered by the study itself. 
Participants may incur cost related to travel for the six week and six month follow-ups. They will be 
compensated as described above. There is no cost to parking at the Briarcrest clinic.

Facilities and locations
Identify and describe the facilities, sites and locations where recruitment and study procedures will be 
performed. 
If research will be conducted outside the United States, describe site-specific regulations or customs 
affecting the research, and describe the process for obtaining local ethical review. Also, describe the 
principal investigator’s experience conducting research at these locations and familiarity with local 
culture.
Potential subjects will be recruited in a private therapy room in the Adolescent Medicine and Eating 
Disorders Clinic, on the 2nd floor of the Briarcrest building. Study procedures, including survey 
completion, will be completed in this same location. Study blood draws and urine tests will be 
completed at the participant’s preferred outpatient laboratory as a part of standard of care; if the test 
ordered is specific to this study, such as a urine drug screen or the six-week LFT this will be obtained at 
the Penn State Children’s Hospital Outpatient Laboratory.
15.2
Feasibility of recruiting the required number of subjects
Indicate the number of potential subjects to which the study team has access.  Indicate the percentage 
of those potential subjects needed for recruitment.
In 2019, approximately 150 patients meeting criteria for potential inclusion (between ages of 13-18, 
needing PHP level of care in the eating disorder clinic, no diagnosis of gender dysphoria or intellectual 
disability, with diagnoses of anorexia nervosa, bulimia nervosa, or avoidant-restrictive food intake 
disorder) were seen for initial evaluation in the eating disorder clinic. Therefore we hope to be able to

Adverse Event Reporting
18.1
Adverse Event Definitions
For drug studies, incorporate the following definitions into the below responses, as written:
Adverse event
Any untoward medical occurrence associated with the use of the drug in 
humans, whether or not considered drug related
Adverse reaction
Any adverse event caused by a drug
Suspected adverse 
reaction
Any adverse event for which there is a reasonable possibility that the drug 
caused the adverse event.  Suspected adverse reaction implies a lesser degree 
of certainty about causality than “adverse reaction”.

Reasonable possibility.  For the purpose of IND safety reporting, 
“reasonable possibility” means there is evidence to suggest a causal 
relationship between the drug and the adverse event.
Serious adverse 
event or Serious 
suspected adverse 
reaction
Serious adverse event or Serious suspected adverse reaction: An adverse event 
or suspected adverse reaction that in the view of either the investigator or 
sponsor, it results in any of the following outcomes: Death, a life-threatening 
adverse event, inpatient hospitalization or prolongation of existing 
hospitalization, a persistent or significant incapacity or substantial disruption 
of the ability to conduct normal life functions, or a congenital anomaly/birth 
defect. Important medical events that may not result in death, be life-
threatening, or require hospitalization may be considered serious when, based 
upon appropriate medical judgment, they may jeopardize the patient or 
subject and may require medical or surgical intervention to prevent one of the 
outcomes listed in this definition. 
Life-threatening 
adverse event or 
life-threatening 
suspected adverse 
reaction
An adverse event or suspected adverse reaction is considered “life-
threatening” if, in the view of either the Investigator (i.e., the study site 
principal investigator) or Sponsor, its occurrence places the patient or research 
subject at immediate risk of death.  It does not include an adverse event or 
suspected adverse reaction that had it occurred in a more severe form, might 
have caused death.

Approval: 8/23/2024


Page 37 of 45 (V.01/21/2019) 
Unexpected 
adverse event or 
Unexpected 
suspected adverse 
reaction.  
An adverse event or suspected adverse reaction is considered “unexpected” if 
it is not listed in the investigator brochure, general investigational plan, clinical 
protocol, or elsewhere in the current IND application; or is not listed at the 
specificity or severity that has been previously observed and/or specified.
For device studies, incorporate the following definitions into the below responses, as written:
Unanticipated 
adverse device 
effect
Any serious adverse effect on health or safety or any life-threatening problem 
or death caused by, or associated with, a device, if that effect, problem, or 
death was not previously identified in nature, severity, or degree of incidence 
in the investigational plan or IDE application (including a supplementary plan 
or application), or any other unanticipated serious problem associated with a 
device that relates to the rights, safety, or welfare of subjects.
18.2
Recording of Adverse Events
Address the frequency and process for eliciting adverse event information from research subject, e.g., 
“Research subjects will be routinely questioned about adverse events at study visits.”
In the response, incorporate the following as written:
All adverse events (serious or non-serious) and abnormal test findings observed or reported to study 
team believed to be associated with the study drug(s) or device(s) will be followed until the event (or 
its sequelae) or the abnormal test finding resolves or stabilizes at a level acceptable to the 
investigator.
An abnormal test finding will be classified as an adverse event if one or more of the following criteria 
are met:

The test finding is accompanied by clinical symptoms

The test finding necessitates additional diagnostic evaluation(s) or medical/surgical 
intervention; including significant additional concomitant drug treatment or other therapy
NOTE: Simply repeating a test finding, in the absence of any of the other listed criteria, does 
not constitute an adverse event.

The test finding leads to a change in study drug dosing or discontinuation of subject 
participation in the clinical research study

The test finding is considered an adverse event by the investigator.
Research subjects will be routinely questioned about adverse events at both study visits and routine 
care for PHP. 
All adverse events (serious or non-serious) and abnormal test findings observed or reported to study 
team believed to be associated with the study drug(s) or device(s) will be followed until the event (or its 
sequelae) or the abnormal test finding resolves or stabilizes at a level acceptable to the investigator.
An abnormal test finding will be classified as an adverse event if one or more of the following criteria are 
met:

The test finding is accompanied by clinical symptoms

The test finding necessitates additional diagnostic evaluation(s) or medical/surgical intervention; 
including significant additional concomitant drug treatment or other therapy
NOTE: Simply repeating a test finding, in the absence of any of the other listed criteria, does not 
constitute an adverse event.

18.3
Causality and Severity Assessments
By submitting this study for review, you agree to the following statement – DO NOT ALTER OR DELETE: 
The investigator will promptly review documented adverse events and abnormal test findings to 
determine 1) if the abnormal test finding should be classified as an adverse event; 2) if there is a 
reasonable possibility that the adverse event was caused by the study drug(s) or device(s); and 3) if the 
adverse event meets the criteria for a serious adverse event.
If the investigator’s final determination of causality is “unknown and of questionable relationship to the 
study drug(s) or device(s)”, the adverse event will be classified as associated with the use of the study 
drug(s) or device(s) for reporting purposes.  If the investigator’s final determination of causality is 
“unknown but not related to the study drug(s) or device(s)”, this determination and the rationale for the 
determination will be documented in the respective subject’s case history.
18.4

Reporting Adverse Reactions and Unanticipated Problems to the Responsible IRB
By submitting this study for review, you agree to the following statement – DO NOT ALTER OR DELETE: 
In accordance with applicable policies of The Pennsylvania State University Institutional Review Board 
(IRB), the investigator will report, to the IRB, any observed or reported harm (adverse event) 
experienced by a subject or other individual, which in the opinion of the investigator is determined to be 
(1) unexpected; and (2) probably related to the research procedures. Harms (adverse events) will be 
submitted to the IRB in accordance with the IRB policies and procedures.
18.6
Unblinding Procedures
Describe the procedures for unblinding study therapy on a subject, including documentation of this in 
the subject’s source document. Include example(s) here why someone might unblind a study. In most 
cases, the unblinding will be part of managing a serious adverse reaction and will be reported with the 
serious adverse event. However, in cases where unblinding was not associated with a serious adverse 
event, such actions should be reported in a timely manner.
If unblinding becomes necessary, this can be done by submitting a request for and filling out the given 
unblinding form to the pharmacy. Unblinding may be necessary in the event of need for opioid 
painkillers, such as after MVA or other accident. Participants taking study article may not experience 
relief of acute pain from typical doses of opioid pain medications, therefore unblinding for appropriate 
pain management may be appropriate.  
18.7
Stopping Rules
In studies with a primary safety endpoint or studies with high risk to study subjects, provide the rules 
that define the circumstances and procedures for interrupting or stopping the study. If an independent 
Data and Safety Monitoring (DSMB) or Committee (DSMC) is set up for the study, the same stopping 
rules should be incorporated into the safety analysis plan as well.
Monitoring for safety of the study article will be completed in accordance with Federal Food and Drug 
Administration requirements for surveillance of drug-induced liver injury (DILI), in accordance with Hy’s 
law. 
The study will be stopped early in the event of certain specific conditions that are more likely to be due 
to study intervention than to the disease itself. Several possible adverse effects of this medication can 
also be common features of eating disorder or eating disorder treatment itself, including worsening

normal for age during the course of the study. 

AST or ALT levels elevated more than five times the upper limit of normal in any participant at 
any time. 

One participant with elevated serum total bilirubin to more than twice the upper limit of normal 
for age with evidence of pure hepatocellular injury (that is, no evidence of obstruction, 
malignancy, genetic disease, other medication effects, viral or bacterial infection) and AST or 
ALT elevation greater than three times the upper limit of normal for age. 

New diagnosis of liver failure of any participant

Any other serious medical or psychiatric condition felt to be potentially related to the study 
article. 
Any suspected case of drug-induced liver injury will be reported to the Food and Drug 
Administration using the specified information provided in the FDA’s document, Guidance for Industry 
Drug-Induced Liver Injury: Premarketing Clinical Evaluation. 
Should any participant demonstrate elevation of AST/ALT above the upper limit of normal for 
age, the study article will be discontinued. AST and ALT measures will be obtained twice weekly until 
they have normalized. More complete history will be obtained, specifically with respect to medications, 
supplements, recreational drug use history, travel, and chemical exposure. Participants with elevation of 
AST and ALT will also be evaluated for acute viral hepatitis types A, B, C, D, and E; autoimmune hepatitis, 
alcoholic hepatitis, non-alcoholic steatohepatitis, biliary tract disease, and hypoxic/ischemic 
hepatopathy. The liver’s function will be assessed directly via measurement of direct bilirubin and 
nternational normalised ratio (INR).

Page 42 of 45 (V.01/21/2019) 
For multi-center studies or single site studies involving significant risk, an independent monitor 
may be required (e.g., monitoring by the staff of the PSU quality assurance program office(s) or 
by a clinical research organization).
The principal investigator assumes final responsibility for monitoring the safety of this study. 
Monitoring for adverse effects to medication will occur at all biweekly medical appointments as 
a part of routine care during PHP. The principal investigator will monitor the conduct of the 
study at regular monthly intervals. 
Scores from all psychiatric measures obtained at enrollment and three weeks will be recorded in 
REDCap and stored on encrypted drives using minimal PHI. All Excel files will be password-
protected and accessible only to study personnel. If the participant is still in PHP at the six week 
timepoint, psychiatric measures will be obtained and recorded in Excel as before; if the 
participant has completed PHP (and therefore is no longer coming to clinic on a daily basis), the 
participant will be emailed the study metrics via RedCap using secure email. Six month follow-up 
metrics will be obtained via secure email through RedCap as described for some six-week 
follow-ups. Their responses in RedCap will be exported to Excel and then analyzed. Lab results 
will also be stored in Excel using similar encryption. 
The study will be monitored by the Clinical Trial Monitoring Team from the Department of 
Public Health Sciences at Penn State Hershey College of Medicine. The monitors will provide an 
independent review of the regulatory and subject records and the data collected to assure 
compliance with the protocol, GCP, and applicable federal regulations. The monitoring will occur 
at regular intervals after the enrollment of the first subject and the times will be predetermined 
by the monitoring plan developed by the Clinical Trial Monitoring Team.
All information will be available only to study personnel. All files will be maintained on Penn 
State Health drives with password protection. If study personnel needs to access the data 
remotely, they will need two-factor authentication for this process. 
19.1.2 Safety Monitoring
Include this section if FDA regulations apply to this study (see “WORKSHEET: Drugs (HRP-306)” 
and “WORKSHEET: Devices (HRP-307)”. HRP-306 and HRP-307 can be accessed by clicking the

Subject’s Printed Name: _____________________________
We are asking you to be in a research study.
Whether or not you take part is up to you. You can choose not to take part. You can agree to take part 
and later change your mind. Your decision will not be held against you, and there will be no penalty or 
loss of benefits to which you are entitled.
This form gives you information about the research. Please ask questions about anything that is 
unclear to you and take your time to make your choice.
Some of the people who are eligible to take part in this research study may not be able to give consent 
because they are less than 18 years of age (a minor).  Instead we will ask their parent(s)/guardian(s) to 
give permission for their participation in the study, and we will ask them to agree (give assent) to take 
part.  Throughout the consent form, when we say “you”, we mean you or your child.  
KEY INFORMATION  
The following is a short summary of this study to help you decide whether or not to be a part of this 
research. More detailed information is provided later in this form. If you have any questions, be sure to 
ask the study team. 
Why am I being invited to take part in this research study?
We are asking you to take part in this voluntary research study because you have an eating disorder and are 
receiving care in the Partial Hospitalization Program (PHP) for Eating Disorders at Penn State Children’s 
Hospital, Division of Adolescent Medicine
What is the purpose of this research study?
The purpose of this study is to determine the effect of oral naltrexone in adolescents seeking treatment 
for eating disorder. This drug is approved for treatment of another condition but is not approved for the 
use proposed in this research. 
Approximately 60 people will take part in this research study at Hershey Medical Center.

Approval: 10/5/2023


Version Date: 01/18/23
Page 2 of 14 (v.12/19/2018)
How long will the research study last?
The study lasts six months. 
What will I need to do?
You will complete all questionnaires and surveys as provided to you during care in program treatment. If 
you are in the adult Partial Hospitalization Program, you will complete two additional self-report measures 
along with the rest of the measures you take every three weeks during treatment. In addition to your 
regular eating disorder care, you will be provided either study medicine or placebo (a pill that looks like the 
study medication, but which contains an inactive substance instead) to take every day for six weeks. We 
also ask that you complete two extra short surveys at the start of treatment, and again at three weeks, six 
weeks, eight/nine weeks for post-treatment evaluation, and six months after starting treatment. 
You will need to take a urine drug test at enrollment. The results of this test will not go into the medical 
record. 
We ask that you have blood testing at enrollment, week three, and week six to assess for liver problems 
related to the study medicine. If you are already having bloodwork done as part of standard of care, we will 
not ask you to have the same bloodwork done twice. 
All people assigned female at birth participating in this study will have to take a blood test for pregnancy at 
enrollment, and urine pregnancy tests every three weeks for six weeks.
 
What are the main risks of taking part in the study?
For this study, the main risks include loss of confidentiality, risk of randomization, emotional discomfort, 
and risk of incidental findings during the research study. Study team members will do their best to ensure 
that these risks will not occur during the research trial. 
The main risks to know about the study drug are: nausea, possible worsening of mood or depression, and 
pain related to blood draws. Other risks related to the study medication include liver injury and increased 
thoughts of suicide or self-harm. People using opioid medications may experience opioid withdrawal as a 
result of the study medication.
The risks of the study medication in pregnancy are not known. It is not known if the study medication can 
be passed through breast milk. 
What are the possible benefits to me that may reasonably be expected from being in the research? 
We cannot promise any benefits to you from taking part in this study. However, possible benefits include 
faster recovery from your eating disorder. Results of the study may benefit other people in the future by 
helping us learn more about eating disorder treatment
What happens if I do not want to be in this research?
Participation in research is completely voluntary. You can decide to participate or not to participate. It will 
not affect the care you get in PHP.

1.   Why is this research study being done?   
The purpose of this study is to determine the effect of oral naltrexone in adolescents seeking 
treatment for eating disorder. This drug is approved for treatment of another condition but is not 
approved for the use proposed in this research. Oral naltrexone is FDA-approved to treat alcohol 
dependence and to block the effects of opioid medications and drugs. 
Oral naltrexone is contraindicated in: people receiving opioid painkillers, people dependent on 
opioids including those maintained on agonists or partial agonists, people in opioid withdrawal, 
anyone with a positive urine screen for opioids, or anyone with a sensitivity to naltrexone or any 
components of the products. 
This drug has no approved use in patients 17 years of age and younger. 
Approximately 60 people will take part in this research study at Hershey Medical Center. 
2.   What will happen in this research study?
You will be randomly assigned to receive one of the two study treatments, either oral naltrexone or 
placebo. This means that whichever study treatment you receive will be determined purely by chance, 
like flipping a coin. You will have an equal chance of receiving any one of the study treatments. Neither 
you nor the research team will know which study treatment you are receiving, but we will be able to get 
this information quickly if we need it to ensure your safety.
You will receive the same treatment in our eating disorder clinic if you decide to enroll in this study or 
not. If you decide to participate in this study, in addition to routine care you will be randomly assigned to 
take a daily pill of either study medication (naltrexone) or placebo every day for six weeks. You will also 
be asked to fill out various surveys as a part of routine care for eating disorder. In addition to our routine 
surveys, we will ask you to fill out two extra surveys at enrollment, three weeks, six weeks, weeks 8/9 
post-treatment, and six months after enrollment. 
All patients are asked to complete bloodwork at enrollment into our partial hospitalization program for 
eating disorders. For those who enroll in this study, they will have a urine drug screen at enrollment. You 
will not be responsible for these costs, and the results will not go in your medical record. Participants will 
also need to have blood tests every three weeks for 6 weeks and at the study start if not required as part 
of standard of care. Women and girls participating in the study will need a blood test for pregnancy at 
enrollment and urine tests for pregnancy at weeks three and six. You will not be responsible for the costs 
of the pregnancy tests (if you need them), or for the blood tests.
Blood testing will be performed by venipuncture, or a needle inserted into a vein by a trained 
professional.  The total volume of blood draw for this study is expected to be less than 18ml over the 
entirety of the study. This is about the same as three and a half tablespoons. 
If you participate in this study, we will give you a $25 Greenphire Clincard, which is an electronic gift 
card that can be used as a debit or credit card. 
We ask that you return for a follow-up visit at 6 months after enrollment, which is a part of routine eating 
disorder care. In addition to routine care, we ask that you complete the same battery of surveys. If your

medical provider decides that you do not need to come in for routine medical care, we will send you the 
surveys via secure email, and you will still have the opportunity to get an additional $25 on your Clincard. 
Participants will receive a total of $50 in Greenphire Clincards.
We have developed the following table to show when all study interventions are planned to happen. 
Thinks marked with a superscript o are things that only happen for the study, and are not a part of 
routine care in PHP or IOP.

A majority of these screening tests would be done even if you do not take part in the research study. 
These tests are routine for patients with your disease who are about to start therapy.
The study team will monitor the content of your questionnaires during the six months you are enrolled 
in this study but will not be responding to any of the information in “real time.” This means we may not 
be immediately aware of any entries you make that could indicate health treatment is needed. If you are 
feeling depressed or suicidal, or are having difficulty coping, please contact your primary doctor or go to 
your local emergency room as soon as possible.
If you are pregnant or nursing, you will be excluded from participation in the study. If you are a sexually 
active person, you must be willing to use a highly effective method of birth control, such as intrauterine 
device, birth control pills, contraceptive implant, contraceptive patches, contraceptive vaginal ring, or 
injectable contraception. Condoms alone are not considered a highly effective form of birth control. If 
you become pregnant during the study, we will have to take you out of the study. You can continue with 
your eating disorder care even if you are withdrawn from the study.
If, during the course of this study, you engage in sex where a penis enters a vagina either without the use 
of contraception or with contraceptive failure (such as a broken condom with no second method of 
contraception), you will be offered a prescription for emergency contraceptive (ulipristal acetate or 
levonorgesterel 1.5mg) within 72 hours after sex and pregnancy testing 14 days after the episode of sex 
with referral according to results. You will also be withdrawn from the study. You can continue with your 
eating disorder care even if you are withdrawn from the study.
If your urine drug screen is positive for opioid substances, you will be provided a referral for addiction 
treatment services, which you may choose to accept or to decline. You will be excluded from participation 
in the study.
What are my responsibilities if I take part in this research? 
If you take part in this research, your major responsibilities will include: 

Taking your medicine every day

Blood tests at enrollment as part of routine care, and blood tests every three weeks for 6 weeks (at 
week 3 and week 6). 

Urine pregnancy tests at weeks three and six for all assigned female patients

For your safety, you must tell the study doctor or nurse about all the prescription drugs, herbal 
products, over-the-counter drugs (OTC), vitamins and other supplements you are taking.  Check with 
the study doctor before starting any new medicines (including prescription, OTC drugs, vitamins and 
herbal supplements) or changing doses of medications that you are already taking.  

You will be asked to complete two surveys every three weeks in addition to the routine surveys in 
PHP and IOP

Disclosure of coitus during study participation if there was no use of contraception or the conception 
failed

3.   What are the risks and possible discomforts from being in this research study?  
You will be assigned to a treatment program by chance. The treatment you receive may prove to be 
less effective or to have more side effects than the other research treatment(s) or other available 
treatments. If you are in the group that receives placebo, your condition will be treated only with 
the standard of care and not with additional study medication.
There is a risk of loss of confidentiality if your medical information or your identity are obtained by 
someone other than the investigators, but precautions will be taken to prevent this from happening.
Oral naltrexone is associated with the following adverse effects: nausea, possible worsening of 
mood or depression, liver injury and increased thoughts of suicide or self-harm. People using opioid 
medications may experience opioid withdrawal as a result of the study medication.
If you are a person who can become pregnant: You should understand that you must not be 
pregnant when you enter the study. You also must not become pregnant during the study. If you are 
or become pregnant, the treatment involved in this study may hurt you or the baby. It is important 
for you to understand that you need to use prescription birth control while on this study. Check with 
your doctor about what kind of birth control methods to use and how long to use them. Some birth 
control methods might not be approved for use in this study. You may be tested for pregnancy to 
make sure that you are not pregnant. If you become pregnant during this study, you must notify the 
study doctor or study staff right away.
Some of the questionnaires and interview questions will be about your feelings, such as depression, 
sadness and anxiety. If your responses indicate that you are having suicidal thoughts or may be at 
risk of hurting yourself or others, we will need to respond to that. The response may involve 
breaking confidentiality and contacting a licensed mental health professional or a law enforcement 
officer. All patients who express any suicidal thoughts will be referred for follow-up mental health 
counseling.
You may get tired or bored when we are asking you questions or you are completing questionnaires. 
You do not have to answer any question you do not want to answer.
4.   What are the possible benefits from being in this research study?   
4a. What are the possible benefits to me?
There is no guarantee that you will benefit from this research. If you are assigned to the active study 
drug group, the possible benefits you may experience from this research study include faster 
recovery from eating disorder. If you are assigned to the placebo group, you are not expected to 
benefit from this research.    
4b. What are the possible benefits to others?
The results of this research may guide the future treatment of eating disorders
 
5.   What other options are available instead of being in this research study?
You may choose not to be in this research study. You do not have to take part in this study to be treated 
for your condition. If you choose not to participate, you will still be offered standard treatment at the 
partial hospital program, which includes completing other clinic questionnaires.

6.   How long will I take part in this research study?
You will be enrolled in the study for six months. This does not change how long you will be in our eating 
disorder program. You will be given study medication or placebo weekly while you are in programming 
or for six weeks, whichever happens first. You will be asked to visit the research site once after you 
finish PHP. 
7.   How will you protect my privacy and confidentiality if I decide to take part in this research study?
7a.  What happens to the information collected for the research?
Efforts will be made to limit the use and sharing of your personal research information to people who 
have a need to review this information. Reasonable efforts will be made to keep the personal 
information in your research record private. However, absolute confidentiality cannot be guaranteed, 
and there may be situations where disclosure is required by law. 
In our research files at Penn State Health (PSH) and Penn State College of Medicine (PSU) we will 
include these identifiers: name/initials, electronic mail address, and medical record numbers.

A list that matches your name with your code number, which is a unique number used to identify 
you in the research record, will be kept in a locked drive in Dr. Roden’s computer. No physical list 
will be kept. 

Your research records will be labeled with your study code number and will be kept in a safe area in 
Dr. Roden’s research office.

 Results of some of the research-related clinical tests (including but not limited to liver function 
tests and pregnancy tests) will be kept in your PSH medical record. Results of your urine drug 
screen will not be in the medical record.

Results from this study will be provided upon request. The status and available results of the study 
are visible to the general public on clinicaltrials.gov, and are updated on a regular basis.
7b. What will happen to my research information and/or samples after the study is completed?
We will not be storing any of your information or biological samples for use in future studies. Your 
information and biological samples will not be shared with any other investigators for use in future 
studies. 
Most tests done on samples in research studies are only for research and have no clear meaning for 
health care.  If the research with your identifiable information or samples gives results that do have 
meaning for your health, the researchers will contact you to let you know what they have found. 
No biological specimens will be used for commercial profit. 
No biological specimens will be used for genomic sequencing. 
7c. How will my identifiable health information be used?
In general, under federal law (including the Health Insurance Portability and Accountability Act – HIPAA

Sometimes a Principal Investigator or other researcher moves to a different institution. If this happens, 
your identifiable health information and samples may be shared with that new institution and their 
oversight offices. PHI will be shared securely and under a legal agreement to ensure it continues to be 
used under the terms of this consent and HIPAA authorization.
We may remove identifying information from your protected health information.  Once we do this, the 
remaining information will not be subject to the privacy laws.  Information without identifiers may be 
used or disclosed with other people or organizations for purposes besides this study.
Because research is an ongoing process, your permission for the use, storage and sharing of your health 
information will continue indefinitely.

9.
Will I be paid to take part in this research study?
You will receive a $25 Greenphire Clincard at enrollment and six months for your participation in this 
research study for a total of $50. If you do not complete the study for any reason, you will be paid

that your funds are loaded onto and can be used at your discretion.  The research team will give 
Greenphire some personal information about you, as described below. Greenphire will only use your 
personal information to process this reimbursement and will not share it with anyone for any other
