Lay Summary of Proposed Research
Schizophrenia (SZ) is a highly debilitating neuropsychiatric disorder of young adulthood onset and a leading 
cause of disability worldwide. While treatments delivered at early stages of the disorder may be effective at 
reducing psychosis or altering the course of the disease, there are currently no biomarkers capable of 
identifying subjects in early stages of SZ who are likely to respond to treatment and would be good 
candidates for available proactive, symptomatic or future disease-modifying treatments; or those who would 
not respond and can be spared unnecessary medication exposure. The lack of these vitally important 
biomarkers provides a compelling rationale for the present multidisciplinary research project, which aims to 
develop and validate highly promising noninvasive and objective proton magnetic resonance spectroscopy 
(1H MRS)-based biomarkers for monitoring treatment response in early stages of SZ. In support of the 
viability of this overall objective is a large body of data, reported by the applicants and others, that show (a) 
that levels of glutamate (Glu) and - aminobutyric acid (GABA) – respectively, the major excitatory and 
inhibitory amino acid neurotransmitter systems - are abnormally elevated in medication-naïve and 
unmedicated first episode and chronic SZ patients; (b) that the effect of treatment with antipsychotic 
medications in these populations may be to lower or normalize brain levels of both Glu and GABA. To 
investigate the potential of these in vivo brain Glu and GABA abnormalities to serve as biomarkers of 
treatment response in early-stage SZ, the applicants propose to use 1H MRS to measure Glu and GABA 
levels in the largest cohort of medication-free SZ subjects to date, at baseline and following 4 weeks of 
antipsychotic treatment.
Background, Significance and Rationale
Over the past 50+ years, several heuristic models of SZ pathophysiology have been proposed. None, 
however, has commanded more attention than the dopamine (DA) hypothesis (Carlsson and Lindquist 1963; 
Snyder 1976) which, in its classical formulation, posits that hyperactivity of DA transmission is responsible 
for at least some of the symptoms of the disorder. The ability of DA D2 receptor antagonists to ameliorate 
the positive symptoms of SZ, and of DA agonists to exacerbate these symptoms in patients and provoke

Protocol Summary Form

psychotomimetic symptoms in normal subjects, lent strong support to the DA hyperactivity hypothesis. 
However, despite its confirmation in vivo by neuroimaging in the late 1990s (Laruelle et al 1996; Abi- 
Dargham et al 1998; Laruelle and Abi-Dargham 1999; Breier et al 1997, 1998), the hypothesized striatal 
hyperdopaminergia in SZ could not account for the negative symptoms and cognitive impairment that 
contribute enormously to the long-term disability in the disorder (Davis et al 1991).
The hypothesis that SZ might be associated with deficiency in the function of the Glu N-methyl-Daspartate 
(NMDA) receptor addresses some limitations of the DA hyperactivity model (Javitt and Zukin 1991; Olney 
and Farber 1995; Tamminga et al 1995). In contrast to the DA agonists, which reproduce only the positive 
symptoms, it was observed that the Glu NMDA receptor antagonists phencyclidine (PCP) and ketamine 
could produce a number of both the positive and negative symptoms of SZ in normal subjects, as well as 
exacerbate these symptoms in patients (Javitt and Zukin 1991; Tamminga 1998; Coyle 1996; Krystal et al 
1994; Krystal et al 1999). Therefore, the NMDA receptor hypofunction (NRH) hypothesis offered a very 
compelling pharmacological model of the illness, which more recent research has extended and shown to be 
associated with a hyperglutamatergic state (Moghaddam et al., 1997). In sum, the preceding considerations 
lend support to the emerging neurochemical hypothesis of SZ that integrates the Glu or NRH model and 
GABA dysfunction with the DA model (Olney and Farber 1995; Carlsson et al 2001; Lodge and Grace 
2007). We will assess treatment response to DA-based antipsychotics in medication-free SZ subjects 
through measurements of cortical Glu and GABA levels, which have the potential to demonstrate the 
proposed MRS biomarkers across both dopaminergic and glutamatergic/GABAergic components of 
intervention efficacy in SZ to provide further support for this neurochemical model.
The overall objective is to develop and validate in vivo proton magnetic resonance spectroscopy (1H MRS) 
measures of the amino acid neurotransmitters, GABA and glutamate, as reliable and objective biomarkers of 
full psychosis, as well as “target engagement” biomarkers for monitoring the therapeutic response in 
schizophrenia, identifying novel glutamate- and GABA-based treatment targets and/or advancing our 
understanding of the underlying brain mechanisms. Such biomarkers could enable the objective assessment 
of disease progression and therapeutic response to existing and emerging treatments.
Specific Aims and Hypotheses
Specific Aims and Hypotheses
pastingAim 1 To measure DCA and MPFC GABA and Glu levels in 60 medication-free SZ subjects across 
two study sites at baseline and then following 4 weeks of treatment with risperidone, an approved second- 
generation antipsychotic, according to standard of care in comparison with 30 age- and sex-matched healthy 
controls across two study sites at baseline and at 4 weeks.
Aim 2 Clinical Correlations: To confirm that neurotransmitter levels will correlate with clinical status and 
antipsychotic treatment/response as assessed by a battery of established clinical ratings.

Is eligibility screening for this study conducted under a different IRB protocol? 
No
Describe procedures used to obtain consent during the screening process
The consent process is a multistep process, whereby information about the risks and benefits of the study 
will be provided to potential subjects across several sessions. The number of sessions over which this 
information will be provided will depend on how well the subject understands and retains the information. 
The process begins with the subject initiating contact via telephone. The research staff provide a brief 
description of the study. Thereafter, potentially eligible candidates are scheduled for a face-to-face 
interview. The study procedures will be described as a research tool with potential to enhance our 
knowledge about treatments for schizophrenia. Subjects will also be informed of all potential risks of 
participation. Subjects will be required to read the informed consent form, and the investigator additionally 
describes the risks and discomforts.
To ensure that the subject understands the study, the subject will be asked questions about the study 
procedures and the risks associated with participation. If any concern arises that the subject did not fully 
understand the study, the PI may decide that the subject is not suitable for participation. If the subject is 
suitable and still interested, after all questions have been answered, the PI will ask the subject to sign the 
informed consent form. Any subject who appears incapable of providing informed consent will be excluded. 
Subjects will be informed that they can decline to participate in the study without penalty, and given the 
opportunity to withdraw from the study prior to analysis of their data. Following the resolution of any 
questions, the subjects will be asked to sign the consent form, if he/she agrees to participate.
Remote/virtual Procedures: Remote procedures will be similar to in person procedures except that we will 
use Redcap to obtain signed consent (using the e signature feature) on the consent forms and HIPAA forms. 
This may occur by either phone or video. If a subject is unable to use Redcap for any reason, we will accept 
a consent form that is signed and scanned and sent to us. The consent discussion process will include 
discussion of the technology HIPAA-compliant platforms to be used and any concerns the patient may have, 
such as access to a private space in which to take calls, or accessibility—access at home to adequate 
devices, cell signal, or wifi.

Independent Assessment of Capacity
You have indicated that your study involves subjects who MAY LACK capacity to consent. 
Does this study require an independent assessment of capacity?
Yes
Methods/procedures for capacity assessment
Subjects who do not have decision-making capacity will not be recruited for this study. Capacity will be 
assessed independently by an independent clinician who is not a member of the research team. Any licensed 
psychiatrist or psychologist (MD/PhD) who works in the New York State Psychiatric Institute and has 
completed CITI training may assess capacity.

Remote/virtual Procedures: Remote procedures will be similar to in person procedures except that we will 
use Redcap for the patient and the independent clinician performing capacity evaluation. This may occur by 
either phone or video. If a patient is unable to use Redcap for any reason, the clinician performing capacity 
evaluation will use phone to contact the patient and will access Redcap for signature. As with the consent 
procedures we will discuss with the patient the technology HIPAA-compliant platforms to be used and any 
concerns the patient may have, such as access to a private space in which to take calls, or accessibility— 
access at home to adequate devices, cell signal, or wifi.
Study Procedures
Describe the procedures required for this study
All subjects will undergo the following procedures:
- Screening: Initial basic study criteria screening questions (age range, presence of symptoms or 
previous diagnosis) may be asked during recruitment prior to the initial screening visit, such as on the 
RecruitMe website. Subjects will be initially evaluated with a medical and psychiatric history and patients 
with schizophrenia will have a physical examination. All participants will have the option of a COVID-19 
saliva test during their first visit. A urine toxicology will be obtained to rule out substance use and a urine 
pregnancy test on females. For patients with schizophrenia, we will also obtain an EKG and blood for TSH, 
electrolytes, liver and kidney function, and CBC, as well as a serum HCG in women. To obtain a research 
diagnosis, the SCID (Spitzer et al 1992) is completed by a trained and reliable interviewer followed by a 
consensus conference. We will not repeat screening procedures (i.e., EKG or lab tests) that have been 
performed within 90 days so as to decrease burden to patients.
- After screening, all subjects will receive the full battery of assessments including the MATRICS, CGI S 
and I, GAF, Hollingshead, Work as Meaning Inventory (WAMI), Fagerstrom test of nicotine dependence, 
and UPSA as described below in the assessments section.
Additional information is collected through the Positive and Negative Syndrome Scale (PANSS) (Kay 
1987), the Clinical Global Impression (CGI) scale, and the Abnormal Involuntary Movement Scale (AIMS) 
(Guy 1976), current and past medications log, medical history, previous treatment history, Substance Use 
Self Report (AUS/DUS), WTAR, Global Assessment of Functioning (GAF), and the Edinburgh inventory 
of handedness (Oldfield 1971). Subjects will be assessed with the above measures at baseline (all 
participants) and at 4 weeks (patients only), with the exception of the Edinburgh inventory of handedness 
and WTAR which will only be obtained at baseline, and the AIMS, which will be administered only to 
patients.
- All subjects will receive a baseline MRI scan with 1H MRS to measure Glu and GABA levels. Images will 
be acquired on the 3T scanner at NYSPI. During this MRI session, which will last up to 2 hours, patients 
will receive structural scans as well as MRS at baseline.

- After completing the baseline MRI scan, medication free SZ subjects will be started on the antipsychotic 
medication risperidone, and will receive antipsychotic medication (Risperidone) for 4 weeks. They will be 
treated naturalistically by a study physician. Risperidone is FDA approved for the treatment of acute and 
maintenance therapy of schizophrenia. Risperidone has been documented to be efficacious in the treatment 
of schizophrenia as well as other psychotic disorders. This medication represents the standard of care in the 
community and has the leading market share by prescription of all antipsychotics (1998 Medicaid Data). For 
inpatients on 5-South the attending psychiatrist, in consultation with the study physicians, will provide the 
medication treatment. For outpatients, the study physicians will provide the medication treatment.
- During the treatment period, all patients will meet with a study physician, once per week (about 3 times 
total). The visit will include assessment for therapeutic effects and adverse events using the PANSS, AIMS, 
CGI, and GAF.
- At 4 weeks, medication free SZ subjects will be assessed with the MATRICS and UPSA, and will undergo 
the same MRI with 1H MRS procedures as at baseline to measure Glu and GABA levels.
Some visits may be conducted remotely using the telephone or HIPAA-compliant video teleconferencing. 
When available we will use recent lab test, physical exam, and EKG results for patient screening. We will 
have study medications sent from the research pharmacy to patient participants whenever possible to 
minimize onsite visits. For patients who need to come onsite for labs, physical, and EKG, we will schedule 
the first MRI on the same day and then start study medications after these results are obtained and patients 
are cleared for medication administration.
All procedures other than the MRI scans can be conducted remotely. However, if a patient does not have 
recent physical exam, EKG, and laboratory test information available, or lacks phone or internet access 
suitable for our screening or medication evaluations, or lacks a suitable address for taking delivery of study 
medication, in-person visits would become necessary. Time required for these visits would be

I attest to follow the COVID-19 Safety Guidelines for Columbia Psychiatry and NYSPI Re-Entry outlined 
in the NYSPI Director’s June 1st memo, which include but are not limited to:
• Infection Control/PPE – Guidelines
• Research participants will only come on-site if absolutely necessary for study procedures.
• No volunteers/externs on-site during Stage 1.
• Clinical research teams will screen their participants for COVID symptoms (night before and 
day of onsite visit, documenting this in the chart), and escort them in and out of the building.
• COVID/COVID-like symptoms in participants will be reported to the IRB via PRISM as an SAE.
Stand By
We will give all subjects the option of being a standby subject. Standby subjects will be
asked to come in on a day when a brain scan is scheduled for another participant. If for some reason the

Protocol Summary Form
7474
Kegeles, Lawrence
Page 16 of 26
original participant does not complete the imaging procedures, the standby will be asked to participate in the 
imaging procedures in place of that person. If the original participant does complete the imaging procedures, 
they standby will be sent home. We expect that standbys will have to wait between 1-3 hours as a standby 
participant. Subjects can choose to be a standby subject by checking one of the boxes found at the end of the 
consent form. We may ask standbys to be standby subjects multiple times. In addition, we may schedule 
more than one standby for a given day.
Monitoring of Patients for Clinical Worsening
Monitoring of patients will occur at the weekly in-person or remote evaluation and medication distribution 
visits with the study physician described above in the study procedures. These visits will include, as noted 
above, clinical evaluation as well as assessment for therapeutic effects and adverse events using the PANSS, 
AIMS, CGI, and GAF. In addition, the study physician’s contact information will be provided with 
instructions to call in case of worsening clinical condition or subjective distress or discomfort at any time 
between weekly visits.
Criteria for Early Discontinuation
A CGI-S or CGI-I of > 5 will trigger an evaluation for removal from the study. 
Criteria for withdrawing a patient from the study at any time:
- Clinically significant adverse events, which would be inconsistent with continuation in the study
- Clinical judgment of the investigator, based on for example, patients being unable or choosing not to 
comply with the study procedures
- Withdrawal of consent and/or patient decision
- Pregnancy
- Any evidence of suicidality/homicidality
- A Change of +2 in the CGI scale or CGI-S or CGI-I of 6 or 7 
Specific Withdrawal Criteria for the Medication Free period include:
A patient will be discontinued from the antipsychotic-free period if he or she experiences any worsening of 
symptoms and/or represents a risk for self-harm or violence as evidenced by: (1) observed or reported 
aggressive/self-injurious behavior; (2) agitation; or (3) subjective distress/discomfort despite clinical 
intervention, or (4) an increase in CGI-S of 2+ or a CGI-S or CGI-I score of 6 or 7.
If any subject suffers a serious adverse event, such as a suicide attempt or an episode of agitation or violence 
towards others, between diagnosis and initiation of imaging, it will result in stopping the study and making a 
report to the IRB and DSMB for evaluation.

Create a table or give a brief description of the instruments that will be used for assessment
All recruited subjects will undergo the following battery of assessments to derive the clinical measures to be 
correlated with the proposed neuroimaging measures: (a) Demographic and clinical characteristics: Patients 
will be assessed for age, sex, ethnicity, medication status (antidepressant/anxiolytic yes/no; antipsychotic 
yes/no; exclusionary if ‘yes’ at entry for all groups), and drug use within past month (i.e. cannabis yes/no, 
‘yes’ will be exclusionary; tobacco yes/no, ‘yes’ will not be exclusionary). Urine toxicology will confirm 
recent drug use status. (b) Positive and Negative Symptoms: Positive and Negative Syndrome Scale 
(PANSS) Kay et al., 1987) (15 minutes) measures positive and negative symptoms and general 
psychopathology. (c) Neuropsychology: Patients will also be assessed with the Global Assessment of 
Functioning (GAF) scale (Jones et al 1995; 3 min), which is a clinician-rated measure of symptom severity 
and role function; the CGI-Severity and –Improvement Scales (CGI-S and CGI-I; 3 min) (Guy 1976) which 
are clinician-rated measures of overall clinical status, and the University of California Performance-based 
Skills Assessment (UPSA; 10 min) scale (Patterson et al 2001). Cognition will be assessed using the 
MATRICS consensus cognitive battery (Green and Nuechterlein 2004; 90 min).
The Abnormal Involuntary Movement Scale (AIMS) (Guy 1976), current and past medications log, medical 
history, previous treatment history, Substance Use Self Report (AUS/DUS), WTAR, Edinburgh inventory of 
handedness (Oldfield 1971), and the MRI Metal Screener are also used. The Hollingshead will be 
performed for socioeconomic status (Hollingshead 1975; 5 minutes) as will the WAMI (Work and Meaning 
Inventory, 10 minutes) and the Fagerstrom test for Nicotine Dependence (Heatherton et al., 1991) will be 
performed as a measure of nicotine dependence.

Research Related Delay to Treatment
Will research procedures result in a delay to treatment? 
Yes
Maximum duration of delay to any treatment
For patients with SZ, participation is associated with delays in initiating antipsychotic treatment from 1 to 
10 days, depending on scheduling of MRI/MRS sessions. Absence of antipsychotic medication treatment 
can result in continuation or worsening of psychotic symptoms, which might include hallucinations, 
delusions, thought disorder, anxiety, depression, suicidality, violence toward self and others, and increased 
risk of accidents. The precautions needed to maintain patients antipsychotic-free until the initial MRI/MRS 
sessions are completed are adequate selection and clinical care. We will exclude patients with suicidal or 
homicidal ideation, history of violence or behavioral dyscontrol, and patients too impaired to give informed 
consent. However, if any medication-free patient does deteriorate, they will immediately be offered 
inpatient care. Inpatients will be monitored very closely by nursing staff and evaluated daily by a physician. 
Medications will be started immediately if it is felt that the continuation of the study might be unsafe.
Specifically, emergence of suicidal or homicidal ideation, risk of elopement, risk of violence or decrease in 
the ability of the patient to understand the nature of the study will automatically result in appropriate 
treatment and exclusion from the study. At any time, the patient can request to withdraw from the study and 
to initiate antipsychotic treatment.

Medication free SZ subjects will not be enrolled if they are currently taking any antipsychotic medications. 
Every effort will be made to ensure the maximum delay to any treatment would be less than 10 days 
(usually between 1-5 days) from consenting procedures, depending on scheduling of MRI/MRS sessions.
Maximum duration of delay to standard care or treatment of known efficacy 
Medication free SZ subjects: 1-10 days between consent to treatment as above. 
Treatment to be provided at the end of the study
Upon completing the protocol (or if a subject drops out or is withdrawn from the study) all subjects will 
have the option of receiving treatment at the Lieber Schizophrenia Research Clinic or remain with their 
current treatment physician or clinic. The Lieber Clinic offers treatment free of charge to individuals who 
participate in research study (medications are not free). It is anticipated that most of the subjects in the 
current study will either start out as subjects in the Lieber clinic or be transitioned to the Lieber clinic during 
the course of the study. For individuals who do not wish to receive follow-up treatment at the Lieber Clinic 
appropriate referrals will be provided.
Risks/Discomforts/Inconveniences
Risks that could be encountered during the study period 
Venous blood sample
Blood sampling in the amount of 15 mL or 1 tablespoon for screening laboratory tests is at a minimal level 
of risk, which includes slight pain, the possibility of bruising, and the possibility of feeling faint. Subjects 
will be advised of these risks. Laboratory tests will not be repeated for patients whose clinical admission 
tests suffice for the screening.
MRI
1. There is a potential risk that confidential health information collected during the course of the study may 
be disclosed to others.
2. There is a potential risk that the participants may find exposure to the clinically sensitive questions, such 
as answering questions about symptoms distressful. They also may become anxious, bored, or fatigued.
3. There is a potential risk from participating in the magnetic resonance imaging (MRI).
a) MRI is not associated with any known adverse effects except for people with metal or magnetic 
implants(such as metallic clips in the brain, metal dust in eyes or cardiac pacemakers). Therefore, a subject 
would be excluded from the study if they had any of these devices or conditions. Careful screening and 
monitoring will be carried out to the time of initial eligibility screening and again at the MRI appointment to 
ensure safety.
b) The scan and/or lying still on the scanning table may become uncomfortable for some individuals. 
Individuals who get severely anxious when in enclosed places will probably find this to be a difficult 
procedure. For subjects who anticipate being anxious during the procedure but are still willing to attempt 
MRI scanning, an experienced MRI technician will be present to check in with the subjects periodically in 
order to ensure comfort or relieve possible fear of being in small enclosed spaces (claustrophobia). Other 
discomforts may include hearing different sounds during the MRI examination. At first, there will be a 
metallic tapping sound that lasts about 30 seconds. This happens while the equipment is being prepared for 
scanning. During the scanning, there will be a combination of rhythmic knocking sounds. These sounds are 
continuous, but are not harmful and earplugs will be provided. Fast imaging sequences may also have the

potential to induce peripheral nerve stimulation, which is described as a light touching or tingling sensation 
on the skin surface and may cause mild discomfort, but is not harmful. Rarely, this can be painful.
Peripheral nerve stimulation is temporary and the sensations stop as soon as scanning has ended. Lastly, 
there is a small risk that cables and button response boxes could become heated. Subjects are urged to report 
any heating sensation or discomforts immediately. Subjects are provided with a means of alerting the staff 
about any discomfort, and can be removed from the MRI machine at any time.
c) The long term effects of being placed in a MRI are unknown, but there have been no reports of any ill 
long–term effects caused by magnets of the same or even higher strength, either here or elsewhere. 
Furthermore, the risks of MRI scanning to a fetus is unknown. Although no known risks are associated with 
pregnancy, we will not scan someone who is pregnant. We will require that women take a urinary 
pregnancy test (that will be provided prior to the scan in order to ensure that they are not pregnant. All 
screening results will be kept confidential.
d) Incidental MRI findings: Scans will be read by a neuroradiologist for incidental findings. If anything 
clinically significant is found, Dr. Ragy Girgis, MD will be notified immediately, and an appropriate clinical 
referral will be provided to the participant. Results of the MRI will be provided to the subjects by a COPE 
physician. Subjects can opt to receive a letter regarding the results of the MRI on the consent forms.
Treatment with Risperidone
Risperidone is a standard atypical antipsychotic medication, with proven efficacy for SZ, and is 
recommended as a first treatment for individuals with SZ (Buchanan et al 2009). Hence, it is an appropriate 
drug for patients entered into this study. Patients who do not do well or cannot tolerate doses of risperidone 
specified here or need adjunctive anticholinergic medication will be offered clinical treatment and be 
discontinued from the study. Patients will be informed before the study that although risperidone is an 
approved medication for treatment of their condition, it is not the only medication or necessarily the best 
medication for them. They will also be informed of potential adverse events associated with risperidone that 
include rare events of neuroleptic malignant syndrome and tardive dyskinesia and common reactions of 
somnolence, anxiety, extrapyramidal effects, dizziness, constipation, nausea, dyspepsia, rhinitis, rash, 
diarrhea, weight gain, menstrual irregularity, and sexual dysfunction.
For patients with SZ, participation is associated with delays in initiating antipsychotic treatment of up to 10 
days (usually 1 to 5 days), depending on scheduling of MRI/MRS sessions. Absence of antipsychotic 
medication treatment can result in continuation or worsening of psychotic symptoms, which might include 
hallucinations, delusions, thought disorder, anxiety, depression, suicidality, violence toward self and others, 
and increased risk of accidents. The precautions needed to maintain patients antipsychotic-free until the 
initial MRI/MRS sessions are completed are adequate selection and clinical care. We will exclude patients 
with suicidal or homicidal ideation, history of violence or behavioral dyscontrol, and patients too impaired 
to give informed consent. However, if any antipsychotic-naïve patient does deteriorate, they will 
immediately be offered inpatient care. Inpatients will be monitored very closely by nursing staff and 
evaluated daily by a physician. Medications will be started immediately if it is felt that the continuation of 
the study might be unsafe. Specifically, emergence of suicidal or homicidal ideation, risk of elopement, risk 
of violence or decrease in the ability of the patient to understand the nature of the study will automatically 
result in appropriate treatment and exclusion from the study. At any time, the patient can request to 
withdraw from the study and to initiate antipsychotic treatment.
Of note, no patients will be withdrawn from medication management solely for the purpose of research.

COVID-related Risks:
There is a risk of exposure to COVID when deciding to go out in public and travel for research. 
Participating in MRI scans may involve some risk of exposure to COVID.
Describe procedures for minimizing risks 
Protection against Risk:
1. Confidentiality will be maintained by assigning each subject a study number, and coding all data 
collected with that number. Neuroimaging data are collected on the scanner and sent directly to a secure 
neuroimaging server at NYSPI. Scan files are named without any identifying information. Only designated 
study personnel (PI and other study team members) could have access to these scanned files. All computer 
databases are password protected, and hard copies of all data and records will be stored in locked filing 
cabinets. The database will be secured with a password, and all computers with access to the data will be 
secured with passwords and locked screen savers. Any data transmitted across the internet between 
evaluators will be encrypted with passwords. No participant names or identifying information will be shared 
across the internet between researchers. Both NYSPI and Columbia’s computer system, where the data will 
be stored, uses state-of-the-art network security systems. An actively managed firewall and intrusion 
detection system monitors and blocks all suspect inbound and outbound network traffic. In addition, for data 
security the University provides secure file servers with hourly snapshot back-ups and off-site file storage. 
All study personnel will be certified to conduct research with human subjects, and will be aware of the 
importance of maintaining strict confidentiality.
2. Furthermore, any distress will be minimized by having a study staff person monitor the subject’s 
experiences during the study procedures. A member of the research team will be available to assist the 
subject if she or he becomes distressed by study procedures. In addition, participants will be told that they 
may decline to answer any questions or discontinue the study if they find procedures distressing. Study staff 
will consult about any possible serious adverse event with Dr. Ragy Girgis or Dr. Lawrence Kegeles 
immediately, and address patient safety. Participants will also be debriefed at the conclusion of the study 
and asked about any possible experiences of distress. If any distress is indicated, this feedback will be 
utilized to modify the study stimuli and/or study procedures to reduce distress.
3. Risks of MRI -- To minimize fatigue, boredom or frustration during clinical and neuropsychological 
assessments and MRI, subjects will be offered breaks or the option to divide the assessments into more than 
one session. Efforts will be made to ensure subjects are comfortable, including providing earplugs. All 
subjects will be instructed at the beginning of the scan to report any sensations or discomforts during the 
scan. An experienced MRI technician will periodically check in with subjects in order to ensure comfort or 
relieve possible fear of being in small enclosed spaces (claustrophobia). Our previous experience scanning 
subjects using these methods with similar MRI protocols suggests that rates of withdrawal from MRI 
procedures due to anxiety or discomfort are extremely low. Given the potential risk for people with metal or 
magnetic implants, careful screening will be carried out both at the time of initial eligibility screening and 
again at the MRI appointment. Subjects are prompted to remove any metal objects they may be wearing or 
have in their clothing prior to scan. If there is any reason to believe that there is a possibility of metal in a 
subject’s body, the subject would need to have an x-ray before having the MRI to confirm that the MRI 
procedure will be safe for the subject. The subject would only have the fMRI scan if the x-ray showed no 
metal fragments. The exposure for this x-ray is about the same as a routine chest x-ray. This is a very small 
amount of radiation and it is unlikely to have any harmful effects. Nevertheless, the subject can choose not

Protocol Summary Form
7474
Kegeles, Lawrence
Page 21 of 26
to have the x-ray and not participate in the study protocol.
Incidental Positive Pregnancy Tests- All female subjects will be provided a pregnancy test kit and asked to 
complete a urinary pregnancy test. Subjects will be informed their tests results will remain confidential.
Study personnel will confirm all pregnancy tests and subjects receive their results immediately. Any 
individual with a positive pregnancy test will no longer be eligible for this study and will not be scanned. 
Incidental MRI Findings- Scans will be read by a neuroradiologist for incidental findings. In the case that an 
MRI technician or other member of the research team suspect that an MRI scan suggests evidence of a 
significant lesion, Dr. Ragy Girgis (Director of COPE) or Dr. Lawrence Kegeles (study PI) will be notified 
immediately. If the reading yields a finding of immediate clinical concern, the radiologist will provide an 
oral report followed by a written note to Dr. Ragy Girgis or Dr. Lawrence Kegeles. Results of the MRI will 
be provided to the subjects by a study physician. Subjects requesting a letter will receive one using the 
language provided by the IRB. Please note: All individuals who appear distressed will also be referred to 
clinical staff at NYSPI, Dr. Ragy Girgis [646-774-5553] or Dr. Lawrence Kegeles [646-774-5560], to 
further discuss any anxiety or distress. Participants who express any anxiety or distress will be offered the 
chance to immediately speak with Dr. Girgis or Dr. Kegeles at completion of the interview, and telephone 
numbers will be provided to contact Dr. Girgis or Dr. Kegeles on the IRB Consent Form that the participant 
will be given a copy of at completion of the interview.
4. Treatment with Risperidone
We will be vigilant for all side effects, EPS and otherwise and will treat them promptly and appropriately if 
they occur. If subjects do experience EPS, akathisia or acute dystonia, this would be managed clinically, as 
follows. For EPS or dystonia, subjects would be given benztropine (Cogentin 1-2 mg/d). For severe 
akathisia subjects would be given lorazepam (Ativan 0.5 mg/d). In the case of Ativan, although it is likely to 
improve akathisia, it may itself leave the subject with some sedation or sleepiness, dizziness and 
unsteadiness. In the case of Cogentin, although it is very likely to rapidly relieve dystonia or EPS, it may 
itself leave the subject with some sedation or sleepiness, dry mouth or slightly blurred vision. Patients with 
clinically significant tardive dyskinesia will not be included in this study. Patients who have had a history of 
NMS from risperidone will not be included in this study. Patients with risk factors that increase the chance 
of seizures will not be included in the study. For the potential metabolic risks of receiving risperidone, these 
risks will be discussed with all patients. All patients will also receive full medical screening at baseline.
Laboratory abnormalities will be followed as clinically indicated.. In addition, as part of this protocol, 
patients are made aware that they may discontinue treatment with risperidone and switch to another 
medication if it is clinically indicated, including for both efficacy and safety reasons.
COVID-related Risks:
Travel: We will instruct subjects to wear a mask in public and while traveling, practice hand hygiene, and 
stay at least 6 feet away from others. We will tell subjects that if they do not feel comfortable traveling to 
the medical center for an appointment, for example if the subway or bus they would normally take is 
crowded, they can reschedule, or we may be able to arrange alternative transportation (if it is the case that 
alternative transportation, such as Uber or Lyft, can be offered). We will minimize onsite visits to lessen this 
risk. We will keep our subjects informed about current public health recommendations, such as federal and 
local government guidelines and directives.
MRI: Risk of exposure in the MRI will be minimized by the COVID safety policies and procedures of the 
MRI Unit, https://nyspi.org/Covid19MRI.

Methods to Protect Confidentiality
Describe methods to protect confidentiality
Confidentiality of all participants will be preserved by coding all datasheets and other data sources and 
maintaining them in locked files. ID numbers will be determined by order of participant entry into the study 
and will not be related in any way to participant identifying data (i.e., the first participant who is recruited 
into the study will be subject #1, etc.). Data will be entered into a computerized database. The database is on 
a computer, which requires a password to access the data. Participants will not be identified by name, only 
by ID number. All records of the participating subjects will be kept in a locked room with access provided 
only to staff members. Public dissemination of the results of this research will be reported on subjects 
collectively and will contain no identifying information about individual participants. Brain imaging data 
from this study shared with GE (General Electric, the MRI scanner manufacturer) or our colleague at 
Columbia Biomedical Engineering, Dr. C. Juchem, for evaluation of scanner data quality, will be de- 
identified raw MRI/MRS data only.
Subjects’ MRIs will be interpreted and the results will be shared with them or a physician whom
they may designate. Their MRI report will be maintained as part of the database at the Columbia University 
MRI Research Center if conducted at the Neurological Institute. Their MRI report will be maintained as part 
of the database at NYS Psychiatric Institute if conducted at the NYS Psychiatric Institute. Any psychiatric 
diagnoses of potential subjects will not be a part of this report. The link to research subjects’ personal 
information will be kept for 7 years after the research is completed, after which time the link will be 
destroyed by research staff and the data will become anonymous. The data will be kept in this anonymous 
form indefinitely. Procedures to ensure confidentiality follow the regulations and policies of all relevant 
study sites.
As described in the personnel section of the PSF, Dr. Dikoma Shungu at Weill Cornell is a member of the 
research team and will have access to identifying information only as necessary.
When done remotely, we will use Redcap to obtain consent on the CFs and HIPAA forms. When sending 
electronic messages to subjects, we will only use NYSPI encrypted email and when sending attachments 
with PHI we will only use the NYSPI secure file transfer website (https://attach.nyspi.org/) or encrypted 
NYSPI email or Redcap. When staff work from home, we will use the NYSPI Onedrive Sharepoint system 
for storing documents or HIPAA compliant storage devices for paper documents. When conducting remote 
visits, we will use telephone or HIPAA compliant video conferencing.
Data Sharing
A data repository has been created by the National Institute of Mental Health (the funding agency for this 
study) that allows sharing of research data and scientific collaboration. The data repository is accessible 
only to qualified investigators. All subject data will be de-identified (subjects' names will not be used) and 
each subject will have a separate identifier called a Global Unique Identifier (GUID) to remove any 
possibility that the data can be linked directly to them. The GUID is a universal subject ID that allows 
researchers to share data specific to a study participant without exposing personally identifiable information 
(PII). All subjects in this study will be assigned a GUID. The following information will be collected and 
entered into the study database to generate a GUID: First name, Last name, Middle name (if applicable),

Month of birth, Day of birth, Year of birth, Physical sex at birth, and Name of city/municipality of birth. 
Once the GUID is generated, all personal information will be deleted from the study database.
During and after the study, the researchers will send deidentified information about subjects' health and 
behavior to NDCT (National Database for Clinical Trials), which is a national database for information from 
clinical trials that are sponsored by the government/NIMH. Other researchers nationwide can then file an 
application with the NIMH to obtain access to deidentified study data for research purposes. Experts at the 
NIMH who know how to protect health and science information will look at every request carefully to 
minimize risks to privacy.
Subjects may decide now or later that they do not want to share their information using NDCT. If so, they 
may contact the researchers conducting this study, and they will tell NDCT, which can stop sharing the 
research information. However, NDCT cannot take back information that was shared before subjects change 
their minds.
Will the study be conducted under a certificate of confidentiality?
Yes, we have already received a Certificate of Confidentiality
Direct Benefits to Subjects
Direct Benefits to Subjects
The potential direct benefits of risperidone treatment are that the subjects are likely to experience an 
improvement in symptoms. Participants will also receive medical and psychiatric assessments by skilled, 
experienced clinicians.
There are no direct benefits associated with participating in the MRI portion of this study.
Compensation and/or Reimbursement
Will compensation or reimbursement for expenses be offered to subjects? 
Yes
Please describe and indicate total amount and schedule of payment(s).
Include justification for compensation amounts and indicate if there are bonus payments.
Subjects will receive $100 per MRI scan (up to 2 scans). In addition, they will receive $50 per session 
(includes up to 3 screening/baseline sessions and weekly sessions; maximum of $550) for additional 
clinical, screening and neuropsychological assessments that they do outside of the MRI machine. If subjects 
agree to come in as a standby subject, they will receive a check for $50. If they come in as a standby subject 
and are asked to participate in the scanning procedures, they will be paid according to the protocol. If they 
come in as a standby subject multiple times, they will be paid $50 for each visit. The money will be sent by 
check to their home address and they can expect to receive it within 2-3 weeks of the study day, or they will

Statistical Analysis Plan 
 
Sections from “Research strategy” 
 
Power Analysis 
 
Aims 1 & 2 – Glu and GABA Differences: In our 6 pilot MRS studies described in Section 
D1.1, we found significant group mean GABA and Glu differences in the MPFC and/or DCA with 
effect sizes greater than 0.9. This would yield power >0.9 to detect the hypothesized elevations 
of these measures at the = 0.05 level (2-tailed) with the proposed sample size of 60 FEMN 
and matched controls. The present studies thus have more than adequate power to detect the 
postulated neurotransmitter differences at all the measurement time points. 
 
Aim 3 – Clinical Correlations. With 25 FEMN subjects or less we found preliminary GABA and 
Glu vs. PANSS correlations that did not survive Bonferroni correction. With 60 FEMN subjects, 
correlations with Pearson coefficient as low as 0.35 will be detected at = 0.05 with 80% power. 
 
Statistical Analyses and Hypothesis Testing 
 
(a) MPFC and DCA GABA and Glu levels in FEMN at baseline and on follow-up: The 
follow-up period is defined as the 4-week treatment period for the FEMN group. For our primary 
analyses, linear mixed-effects models for each region of interest (MPFC, DCA) with group (FEP, 
HC) and MRS outcome measures (GABA and Glu) as fixed effects, will be used for omnibus 
testing. Baseline and follow-up MRS outcome measures will be repeated measures in the 
models. Effects on the outcome measures of gender, ethnicity, will be assessed by ANCOVA, 
using these factors as covariates in the mixed-effects models and accepting the most 
parsimonious covariates according to the Akaike information criterion (Sakamoto et al 1986). 
Significant results from the omnibus testing will be followed with post hoc two tailed independent 
samples Student’s t-tests of the group differences in the baseline, follow-up and follow-up 
change values of the MRS outcome measures. 
 
(b) Clinical Correlations: We will use the Pearson product moment coefficient to test for 
postulated relationships among clinical symptoms (PANSS), treatment response and the MRS 
outcome measures. Effects of covariates will be addressed with ANCOVA as above. 
(d) Missing Data: Maximum likelihood (ML), as implemented robustly in the MPlus 7 software 
package (Muthén & Muthén 1998-2012) will be used to deal with any missing data in our 
regression models. ML is relatively simple, has a high algorithmic efficiency and enables 
incorporation of covariates as auxiliary variables, to allow accuracy and power to be maximized 
in the analysis of data sets with missing values (Enders 2010).
