Lay Summary of Proposed Research 
Lay Summary of Proposed Research
We propose a rigorous clinical trial in depressed patients with moderate to severe suicidal ideation to test 
random assignment to iv infusion of ketamine or midazolam control followed by open continuation 
treatment with antidepressant medication plus supportive case management. The primary goal is to test 
ketamine’s potential anti-suicidal effects versus a similar sedative control medication not known to reduce 
suicidal ideation. Exploratory aims include analysis of potential biological (salivary cortisol) and neuro-
cognitive correlates as well as systematic assessment of suicidal ideation and behavior during continuation 
treatment. 
Background, Significance and Rationale
Background, Significance and Rationale
Suicide and suicide attempts cost an estimated $33 billion annually in the U.S. and immeasurable pain and
suffering. Most suicidal behavior is associated with a depressive disorder, yet medication guidelines for
suicidal patients are virtually nonexistent. The evidence base is severely limited because suicidal patients
are excluded from most antidepressant clinical trials. Several recent studies show rapid improvement in
suicidal ideation, in as little as one hour, in depressed patients after intravenous infusion of sub-anesthetic
ketamine, a glutamate antagonist and commonly used anesthetic. The improvement in suicidal ideation
appears to last several days, however, depression and suicidality are usually chronic, recurring conditions.
Establishing a strong anti-suicidal signal for ketamine in this high-risk population would support an
innovative intervention that could change clinical care for a patient population of public health importance.
Exploratory assessment of suicidal ideation and behavior during continuation treatment could help target
research on strategies to sustain the benefit of ketamine.
Specific Aims and Hypotheses
Specific Aims and Hypotheses
To compare the effect of iv ketamine vs. midazolam infusion on suicidal ideation in a double-blind RCT in
MDD during a major depressive episode (MDE) (N=80) with moderate to severe suicidal ideation (SSI
score = 4 or greater). The study infusion will be given as add-on to current psychotropic medication.
Patients will be randomized to iv ketamine (0.5 mg/kg) or midazolam (0.02 mg/kg) infusion. We
hypothesize that administration of ketamine will produce greater improvement in suicidal ideation 
compared to midazolam at 24 hours after infusion.
An exploratory aim of the study is to compare cortisol awakening response (CAR) between the two
treatment groups. Hypothalamic-pituitary-adrenal (HPA) axis hyperactivity is associated with cognitive

impairment and suicide risk. Glutamatergic and serotonergic systems are closely associated with HPA
activity. We will measure salivary cortisol at baseline and Day 01 post-infusion with 2 saliva samples
collected at each time point, the first immediately on waking and the second 30 minutes later. We
hypothesize CAR magnitude will be lower on Day 01 after ketamine compared to midazolam.

Describe the procedures required for this study
1. Screening
a. We will recruit inpatients or outpatients with a major depressive episode. Referrals
generally come from physicians, clinics, the Presbyterian Emergency Department, and ads in
media including the internet.
b. Subject completes phone screen, approved under IRB #5880R. If subject appears eligible
based on the phone screen, they will be scheduled for an in-person screening visit under
Screening Protocol (IRB #5880R) to determine whether inclusion/exclusion criteria (excluding
medical screening) are met.
c. Subject is given a detailed, verbal explanation of this study and IRB #4815 and given a
copy of both consent forms.
d. Subject gives written informed consent to participate in IRB #4815 and this study, IRB
#6598.
e. Subject receives medical evaluation under this study. Genetics blood sample is under IRB
#4815 (Biological and neuropsychological measures for genetic studies of psychiatric
populations—PI: Oquendo).
f. During the period between enrollment and the infusion, the treating physician will
assess the patient weekly in person or by phone, including a Clinical Global Impression
(CGI) scale. If concerns are noted during a telephone contact, subjects will be brought in
for an in-person visit. If someone has a CGI-I >5 then a repeat CGI-I will be done within 3-4
days and if it remains >5 then the subject will be withdrawn; or 2) their CGI Improvement score is
six or seven on one occasion and the treating psychiatrist assesses that they
cannot safely continue research participation. If after enrollment a subject refuses inpatient
admission that is deemed clinically necessary by the research team they will be withdrawn from
research.
2. Prior Psychiatric Medication
a. For insomnia or anxiety, PRN diphenhydramine, hydroxyzine, zolpidem, or a
benzodiazepine will be permitted. The goal will be a maximum daily dose of lorazepam
2mg during the week pre-infusion. However, no zolpidem or benzodiazepine will be
permitted during the 24 hours pre-infusion. Subjects who at enrollment are taking a
higher benzodiazepine dose will be tapered and converted to lorazepam during the
pre-infusion week. Subjects who show signs of benzodiazepine withdrawal
or cannot tolerate the 24-hours pre-infusion without zolpidem or benzodiazepine will be
withdrawn from the protocol.
b. Current psychiatric medications other than benzodiazepines will be maintained at a
stable dose until post-infusion treatment. Minor dose adjustments may be made pre-infusion,
such as to reduce side effects.
3. Actively Suicidal Patients
a. Patients with imminent (next few days) suicidal plan or intent will only be enrolled as
inpatients. The independent treatment team on the inpatient research unit must agree that
study participation is clinically reasonable.
b. For patients who require hospitalization because of destabilization or suicidal risk,
admission to a NYSPI unit will be available. Hospitalized patients will be discharged from the
hospital when stable as judged by the inpatient staff and the treating psychiatrist as not being
in imminent risk of harm to self/other.

Protocol Summary Form

c. A research psychiatrist will be available by cellphone 24 hours a day, seven days a week.
Patients requiring urgent admission will be brought to the CUMC Emergency Dept. by the
study physician with security assistance, if needed. Non-emergent admissions will be arranged
by the treating psychiatrist, if possible to the 4-Center or 5-South. Patients who are deemed to
require hospitalization, but who refuse, will receive all necessary interventions such as
contacting the local crisis team, family, or Emergency Medical Services.
4. Pre-Infusion Research Measures
a. Baseline clinical and neuropsychological ratings (See Figure 2, attached).
b. Saliva Cortisol: We will measure salivary cortisol using Salivettes (Sarstedt, Germany) at the
following time-points for both the initial infusion and the optional open ketamine infusion: Time-
Sensitive (within 72 hours pre-infusion) and 24 HR Post-Infusion Day (i.e., Day 1 Follow-Up).
The samples will be collected fasting and before the patient has taken any medication that day.
At each time point (Time-Sensitive, 24 HR Post-Infusion Day), patients will be asked to provide
two samples, one immediately on waking up in the morning and a second sample 30 minutes
later. Samples will be processed in the Nathan Kline Institute laboratory of Thomas Cooper,
M.A., who is an expert in these methods.
5. Randomization
a. Patients will be assigned randomly to one of the two treatment conditions: ketamine or
midazolam.
b. Randomization will be stratified on two variables: 1) According to time-sensitive pre-infusion
Scale for Suicidal Ideation (SSI) score of below 8 vs. 8 or above; and 2) According to whether
the subject is currently taking psychiatric medication or not.
c. The infusion medication will be prepared by the NYSPI research pharmacy.
d. Codes linking patient numbers to treatment assignment will be sealed and kept under lockand-
key for all study patients.
6. Blinding
a. The patient, study psychiatrist, and assessors will be blind to infusion allocation.
b. An un-blinded pharmacist, who is not part of the research team, will dispense the infusion
treatments.
c. To test adequacy of the blind, after completion of post-infusion research assessments, all
subjects and research personnel will each complete a brief questionnaire asking them to guess
subjects’ infusion group status.
d. Infusion responders will be informed by the pharmacy via a letter which infusion they
received at the end of their 6-month participation in our clinic or when they stop treatment in
our clinic, whichever comes first. Infusion non-responders will be informed which infusion they
received after research measures are complete on the post-infusion day. The DSMB may
request unblinded data as needed.
7. Inpatient Infusion Phase
a. To participate in the study, patients must agree to inpatient hospitalization at NYSPI (4-
Center or 5-South units) for the infusion. Our goal will be for the admission to be as short as
possible, approximately 3-5 days, or more if clinically indicated. Patients will be evaluated by a
research physician and the inpatient unit’s independent clinical team and will be discharged
when assessed, according to standard practice, as safe for outpatient treatment in the
research clinic. Patients who need to be kept involuntarily for safety reasons will be withdrawn
from research and treated clinically.

Protocol Summary Form
6598
Grunebaum, Michael
Page 12 of 26
b. We will attempt to schedule the study infusion as close as possible to the date of enrollment,
given time for screening lab results, inpatient admission and BSU scheduling.
c. All patients will be NPO after midnight prior to study infusion and will be escorted by study
staff to and from the BSU where the infusion will occur.
d. No zolpidem or benzodiazepine will be permitted in the 24 hours pre-infusion. We
will monitor patients for signs of withdrawal, such as severe anxiety, diaphoresis,
tachycardia (HR greater than 100), or hypertension (BP greater than 140/90) and if
such signs are present then the infusion will be canceled and benzodiazepine
restarted.
e. For subjects currently taking psychiatric medication, we will give advance notice of
infusion scheduling to anesthesiologist consultant, Dr. Moitra, to confirm his or a backup
anesthesiologist's availability for phone consultation during the infusion, if needed.
f. Pre-infusion blood level of BDNF will be measured by drawing a blood sample
through the iv site. This will be analyzed in the NKI lab of Tom Cooper.
8. Blinded Ketamine/Midazolam Infusion
a. Dose:
i) Patients randomized to ketamine will receive an intravenous infusion of saline solution with
ketamine hydrochloride (0.5 mg/kg; Abbott Laboratories, North Chicago, IL) over the course of
approximately 40 minutes in the BSU of NYSPI with continuous monitoring of the subject by a
study physician.
OR
ii) Patients randomized to midazolam will receive an intravenous infusion of saline solution
with midazolam (0.02 mg/kg) over approximately 40 minutes in the BSU of NYSPI with
continuous monitoring of the subject by a study physician.
b. Vital Signs Monitoring: During study infusion(s), blood pressure, heart rate, respiratory
rate, and oxygen saturation will be monitored as follows:
i. -5 minutes
ii. 0 (start of infusion)
iii. Post start of infusion: 5, 10, 15, 20, 25, 30, 35, and 40 minutes (end of infusion)
iv. Post end of infusion: Blood pressure will continue to be obtained until there are two
measurements at least 15 minutes apart that are within 10 mmHg of the baseline diastolic
blood pressure or diastolic blood pressure is below 85. Respiratory rate and oxygen
saturation will continue to be obtained until there are two measurements at least 15
minutes apart that are within normal limits (RR of 10 or greater; 02 saturation of 94% or
greater).
c. The physician and Research Assistant who remain in the patient’s room during the infusion
record the vital signs. After the subject is transferred back to their inpatient unit room, the
blood pressure and heart rate will be obtained manually by the unit nursing staff.
d. Intervention for Hypertension: If the systolic blood pressure increases to ≥ 200 or diastolic
blood pressure increases to ≥115 mmHg during the ketamine infusion, the infusion will be
discontinued. The blood pressure will be monitored and if there is no decrease after 15
minutes, then:
1) One dose of sublingual nitroglycerine, 0.3 mg, will be administered.
2) If there is no response within 10 minutes, clonidine 0.1 mg po will be administered
every 30 minutes (total maximum dose 0.6 mg clonidine) until the desired blood

Protocol Summary Form
6598
Grunebaum, Michael
Page 13 of 26
pressure is reached. Desired blood pressure is defined as within normal range or 10
mmHg of baseline diastolic reading.
3) If high blood pressure is symptomatic, i.e., blurred vision, headache, chest pain, the
subject will be transferred to the ER. If they do not respond to the above treatment (d.)
then they will be transferred to the ER.
e. Intervention for Decreased Oxygen Saturation or Respiratory Rate:
1) If 02 saturation is <94%, the patient will be given oxygen via nasal canula; then if 02
saturation returns to ≥94%, the infusion will be continued. If 02 saturation remains
<94% with nasal canula oxygen, then the infusion will be stopped, the anesthesiologist
called, the blind broken, and if the infusion drug was midazolam then the patient will be
given flumazenil unless the anesthesiologist recommends other treatment.
2) If respiratory rate is <10, the infusion will be stopped, the anesthesiologist called, the
blind broken, and if the infusion drug was midazolam then the patient will be given
flumazenil unless the anesthesiologist recommends other treatment.
3) If the patient does not respond to the above treatment, they will be transferred to the
ER.
9. Post-Infusion Lab Tests
a. BDNF, ketamine and norketamine levels will be measured by drawing blood samples with a
blood-draw separate from the iv site. These will be analyzed in the NKI lab of Tom Cooper.
b. Post-infusion saliva cortisol: Same procedure as Pre-Infusion (4b above).
10. Post-Infusion Treatment According to Medications at Enrollment and Responder Status on
Day 01 post-infusion (Responder: 50% or greater reduction in SSI score from pre-infusion
baseline and score < 4):
1a) Responders already taking an antidepressant will receive open clinical
treatment.
1b) Responders not already taking an antidepressant will begin 6-week treatment with open
label sertraline as follows: Open-label sertraline will be titrated to a daily dose of 100 mg or higher
as tolerated. Fluoxetine, paroxetine ER, or escitalopram may be substituted for sertraline if a
subject has had a failed adequate previous trial of the preferred drug due to side effects or lack of
response. An adequate trial is defined as at least 2/3 maximum PDR dose for at least 6 weeks. If
none of these SSRIs is acceptable, due to previous failed trials as defined, then other
medication may be used. The dosing schedule will be as follows, but can be attenuated if
required due to side effects:
Week 1: sertraline 50 mg daily (or fluoxetine 20 mg or paroxetine ER 25 mg or escitalopram
10mg).
Week 2: sertraline 100 mg daily (or fluoxetine 40 mg or paroxetine ER 50 mg or escitalopram
20mg).
Week 3-6: Optional increase to sertraline 150 mg (or fluoxetine 60 mg or paroxetine ER 75 mg or
escitalopram 40mg) daily, or higher, if indicated by clinical assessment.
Response: Patients not responding adequately to sertraline (CGI Improvement score of 6 or
worse 2 weeks in a row) or who develop intolerable side effects will be switched to fluoxetine,
paroxetine ER, escitalopram, or if none is acceptable, due to previous failed trials as defined
above, then to other medication. Patients who relapse will receive open treatment.
Concomitant medication: For insomnia or anxiety, diphenhydramine, hydroxyzine,
zolpidem, or a benzodiazepine (lorazepam up to 4mg total daily dose or equivalent) will be

6598
Grunebaum, Michael
Page 14 of 26
permitted. If addition of antipsychotic or mood stabilizing medication is required due to agitation,
psychosis, or manic symptoms, then the patient will be withdrawn from research and treated
openly.
2) Non-responders: For patients who are non-responders at 24 Hrs Post-Infusion (Day 01), the
blind will be broken after Day 01 post-infusion research measures are complete. Non-responders
who received midazolam will be offered an optional open-label ketamine infusion, following the
same procedure as above. Neuropsychological testing will be repeated on Day 01 after the openlabel
ketamine infusion, during the inpatient stay.
a) Responders to optional open-label ketamine infusion not already taking an
antidepressant will receive the SSRI continuation treatment as above (see 1b).
Responders who later relapse will receive open treatment.
b) Non-responders to first infusion who received ketamine (not eligible for second
infusion) or who received midazolam but opt not to have a second infusion will receive
open treatment.
c) Non-responders to optional open-label ketamine infusion and responders already
taking an antidepressant will receive open treatment.
d) Non-responders at Day 01 after ketamine will have an additional Scale for
Suicidal Ideation (SSI) rating at Day 03 to assess potential delayed response.
3) All patients receive supportive management according to the NIMH treatment manual of
Fawcett et al.6 This condition is similar to what many patients receive in the community when their
primary treatment is pharmacotherapy with a psychiatrist as the sole clinician, but is enriched by
clinical and ethical necessity with additional monitoring and assessment. This will ensure that
patients are being carefully managed. As described in the manual,6 clinical management will
emphasize a positive, collaborative doctor-patient relationship through supportive reassurance,
rationale for treatment, psycho-education, assessment of target symptoms, side effects, and
appropriate dosing, assessment of suicide risk and mental status, and review of procedures to
follow if patients become acutely suicidal.
4) Exploratory research assessments of mood, suicidality, and side effects (per Fig. 2) will
continue for a six-week continuation phase post-infusion, for all subjects. Non-responders who
opt for the open ketamine infusion will start the continuation phase after it. Continuation phase
appointments will be weekly for six weeks, then decreasing to at least monthly, as clinically
indicated, for the remainder of the six months.
5) In all follow-up treatments, psychiatrists will be available to patients between sessions for
consultations and emergencies (a research psychiatrist is on-call at all times). Thus, clinical
management will provide careful assessment of the patient's clinical condition to determine clinical
changes, safety, and the need for withdrawal from the protocol. Psychiatrists will evaluate mood,
suicidality, and treatment course to help determine if a patient's condition warrants removal from
the study. Independent, masters or PhD level, raters will systematically assess suicidal ideation
and/or behavior and depression weekly during the 6-week continuation phase for exploratory
analysis.
6) Week 7-24: All patients will be offered free, open, clinical treatment, and then will be referred
for ongoing care.

13. Withdrawal from Study: Subjects will be withdrawn from the study if:
a. They request it for any reason.
b. The PI judges that it is medically unwise to continue in the study, for example if the
subjects are unable to comply with the study procedures.
c. They are unable to tolerate the delay to treatment because of pronounced worsening of
symptoms such as marked agitation or psychotic symptoms. Worsening of suicidal ideation
will not automatically require discontinuation from research, since this is the primary study aim,
as long as the team judges that the patient can be managed safely as an outpatient (e.g. they
have no plan or intent), or they agree to inpatient treatment and the inpatient staff agrees that
the patient may continue research participation.
d. A rise in systolic blood pressure ≥ 200 mm Hg or diastolic blood pressure to ≥ 115 mm
Hg during the infusion.
e. During infusion, if 02 saturation remains <94% with nasal canula oxygen or respiratory
rate <10, then patient will be withdrawn from research and treated clinically as described in
Section 8.e.
f. Other criteria for discontinuation will be appearance of psychosis, mania, severe
agitation, or other deterioration where the treating physician decides that research participation
is unacceptable.
g. During the 6-week SSRI trial: 2 consecutive weekly CGI-I’s >5.

Research Related Delay to Treatment
Will research procedures result in a delay to treatment?
Yes
Maximum duration of delay to any treatment 
Patients will continue their current psychiatric medication. The delay to inpatient admission will not
exceed 2 weeks; if a subject needs a longer delay between consent and beginning
treatment, it will be determined by the study clinician on a case-by-case basis based on
need for delay, clinical stability, and ability to comply with the plan for monitoring. This
period allows the time required for processing lab samples, completion of baseline research
measures, and scheduling inpatient admission for the infusion procedure in the BSU. We will
attempt to minimize this delay period. During this time period the treating physician will stay in
contact with the participant and assess their clinical condition weekly, either in person or via
phone, including the Clinical Global Impressions (CGI) scale. If items of concern are noted during
a telephone contact, the participant will be brought in for an in-person visit. If someone has a CGII
>5 then a repeat CGI-I will be done within 3-4 days and if it remains >5 then the subject will be
withdrawn from research and start clinical treatment. Additionally, if the team judges that this
delay is not clinically acceptable or the participant does not agree to the delay, then the patient will
be withdrawn from research.
Maximum duration of delay to standard care or treatment of known efficacy
As described above, for subjects not already taking an antidepressant, treatment with standard
antidepressant medication plus supportive clinical management will begin on the day after the
ketamine/midazolam infusion, after 24-hour research assessments are completed. This adds 1
day to the delay described above. Non-responders who received midazolam and who choose to
receive a clinical ketamine infusion prior to beginning standard clinical treatment will have an
additional delay of a few days for BSU scheduling, which we will attempt to minimize.
Treatment to be provided at the end of the study
Described in Procedures (Section 10) above.

Clinical Treatment Alternatives
Clinical treatment alternatives
This is a study of sub-anesthetic ketamine’s effect on suicidal ideation in suicidal depressed
patients, with midazolam as an active control. Many treatments for major depressive disorder
exist, such as numerous approved antidepressant medications, ECT, and various
psychotherapies. Relatively little is known about best practices for more suicidal depressed
patients.
Risks/Discomforts/Inconveniences 
Risks that could be encountered during the study period
Potential Risks to Subjects and Procedures for Minimizing Risks:
Risks associated with participation in this study are related to 1) side effects of the medications; 2)
other medication related risks; 3) intravenous catheters; 4) blood drawing; and 5) pregnancy. Dr.
Milak, a co-investigator on this study, has experience with this ketamine dose in our institution and
will consult and supervise on this study’s infusion procedures. Dr. Vivek Moitra, MD, Associate
Clinical Professor of Anesthesiology, Associate Medical Director Surgical Intensive Care Unit,
Associate Program Director, Critical Care Medicine Fellowship, Division of Critical Care, Columbia
University College of Physicians and Surgeons, is experienced with both ketamine and
midazolam, has reviewed this protocol, and is a consultant on this study.
1. Side effects of medications:
1.A. Side Effects of Intravenous Ketamine.
i) Medical Risks. Administration of sub-anesthetic doses of ketamine i.v., such as the 0.5 mg/kg
dose to be used in this study, may induce a modest rise in blood pressure. We have administered
sub-anesthetic doses of ketamine i.v. (0.5mg/kg over 40 minutes) in the setting of a currently
approved MRI/MRS brain imaging protocol at this institution (IRB #5786, PI: J. Mann). The
resulting effects on vital signs for the eleven patients scanned under protocol #5786 are presented
as a function of time in Table 1 below for the duration of the ketamine injection. These modest
increases all peaked and largely resolved by 75 minutes, with vitals returning to near baseline.

Describe procedures for minimizing risks
ii) Specific measures and precautions
Any medical risks from increased blood pressure will be minimized through the careful screening
of potential subjects. Subjects will be excluded for baseline hypertension or any history of
cardiovascular illness. A physician, Dr. Michael Grunebaum (ACLS certified 05/22/2012; copy of
certification attached), will be present during the procedure. If physician coverage for Dr.
Grunebaum is needed (such as vacation), then another ACLS-certified MIND physician (Drs.
Matthew Milak or Martin Lan), who has been trained in the infusion procedure, will be present.
Procedures for hypertension that occurs during the infusion are described above under Study
Procedures. Nausea and vomiting will be treated supportively and, if severe, with anti-emetic
agents; if necessary, administration of ketamine will be discontinued. Subject will be informed that
they should be fasting (12 hours no food, 4 hours no liquids) prior to the ketamine infusion. For
these reasons, the medical risks involved in participation in this study will be minimized.
iii) Psychiatric or Behavioral Risks. Ketamine is an FDA-approved dissociative anesthetic.
Ketamine exposure at the sub-anesthetic dose to be used in this study can be associated with a
moderate dissociative state, which is well tolerated in the majority of cases and is spontaneously
reversible (7). There is extensive clinical experience with ketamine used at anesthetic doses, and
no long-term detrimental effects of ketamine exposure have been reported. It is possible that
ketamine administration will increase the risk of psychosis, even in normal subjects. Ketamine is a
street drug of abuse. As such, it poses the risk that exposure during this study may predispose
subjects to subsequent abuse of this drug. To minimize this risk, current drug or alcohol
dependence or any history of ketamine abuse or dependence will be excluded. We will follow
patients while they are receiving clinical treatment and review any evidence of abuse that may
appear after the ketamine infusion. This dose of ketamine has been safely administered in similar
settings to depressed patients with clinically significant suicidal ideation at least 23 times without

any serious side effects (8, 9).
iv) Specific measures and precautions
The experiment will be carried out in the presence of at least one psychiatrist. In case of severe

Protocol Summary Form
6598
Grunebaum, Michael
Page 21 of 26
agitation, hyperarousal, or psychosis, the blind will be broken. If the patient received ketamine,
they will be treated with benzodiazepine (lorazepam) or neuroleptics, as indicated (see below for
midazolam). The risks of exposing subjects to a drug of abuse potential will be minimized by
explaining this risk to prospective subjects, and by excluding from the study any subjects with
documented or suspected current substance or alcohol dependence.
2.A.2. Side Effects of Intravenous Midazolam
Midazolam is an imidazobenzodiazepine derivative in common use as a sedative and, like
ketamine, anesthetic induction agent, including for routine outpatient procedures such as
colonoscopy (10-12). It is the control medication at a dose of 0.045 mg/kg in the ongoing NIMHfunded
ketamine RCT, “Optimization of IV Ketamine for Treatment Resistant Depression”
(ClinicalTrials.gov Identifier NCT00768430; PI: SJ Mathew). We will use a lower dose of 0.02
mg/kg, which was found in a double-blind RCT of anesthesia pre-medication to produce equal
anxiolysis, but fewer sedative and cardio-respiratory effects compared to 0.06 mg/kg (13). The
lower dose was recommended by our anesthesiologist consultant, Dr. Moitra, as being less likely
to make subjects sleepy, which would make it a less effective control medication.
i) Medical Risks.
a. Midazolam is an imidazobenzodiazepine derivative in common use as a sedative and, like
ketamine, anesthetic induction agent (10-12). It has anxiolytic, hypnotic, muscle relaxant, and
antegrade amnestic effects (10-12). Midazolam is not known to have direct effects on glutamate or
NMDA receptors (10,11). To investigate the potential relationship of anxiety or anxiolysis to
infusion effects on suicidal ideation, we will systematically assess anxiety using a visual analog
scale (14).
b. Midazolam may cause respiratory depression, decreased systolic and diastolic blood pressure
and increased heart rate (10-12) The sub-anesthetic dose we plan to use requires the presence of
a physician, but not an anesthesiologist (personal communication from Eric Heyer, MD, Chief of
Neuro-Anesthesiology, Columbia University Medical Center).
c. Cardio-respiratory effects are usually absent at intravenous sedative doses (0.05-0.15 mg/kg)
and our planned dose is below the low end of this range (10-12). Midazolam has an onset of CNS
activity within minutes, a half-life of 2-4 hours, and psychomotor performance returns to normal
approximately 2 hours after administration (10-12) It is relatively free of other side effects such as
nausea, vomiting, or venous irritation.10-12 Midazolam may cause confusion, but an RCT found it
to be safe even in the elderly (15).
ii) Specific measures and precautions
The risk of respiratory depression with the midazolam dose in this study is expected to be
“miniscule” (personal communication, Dr. Moitra, study consultant). Adverse effects of midazolam
can be reversed with administration of the benzodiazepine antagonist flumazenil (10-12). Specific
Protocol Summary Form
6598
Grunebaum, Michael
Page 26 of 31
interventions for respiratory depression or low oxygen saturation are described under Study
Procedures.
iii) Psychiatric or Behavioral Risks. Midazolam has anxiolytic, hypnotic, muscle relaxant, and
antegrade amnestic effects substantially mediated by its binding to CNS benzodiazepine
receptors and increased GABA activity (10-12). It is not known to have direct effects on glutamate

Protocol Summary Form
6598
Grunebaum, Michael
Page 22 of 26
or NMDA receptors (10-12). Midazolam may cause confusion, but an RCT found it to be safe even
in the elderly (15) Paradoxical excitation has approximately a 10% incidence after midazolam
doses twice as high as the dose we plan to use, is more common among older patients, and is
reversible within 30 seconds with administration of flumazenil (16).
iv) Specific measures and precautions
The experiment will be carried out in the presence of at least one psychiatrist. In case of severe
agitation or hyperarousal, the blind will be broken and if the patient received midazolam, then they
will be treated with neuroleptics and or flumazenil. The risks of exposing subjects to a drug of
abuse potential will be minimized by explaining this risk to prospective subjects, and by excluding
from the study any subjects with documented or suspected current substance or alcohol
dependence.
 
2.A.3. Side Effects of Other Medications
Sertraline (or Fluoxetine, Paroxetine, Escitalopram): The potential side effects of SSRIs include
nausea, sexual function change (orgasmic delay), weight loss or gain, headache and diarrhea,
drowsiness or stimulation, nervousness and/or insomnia, and allergic reactions.
Zolpidem: The potential side effects are diarrhea, dizziness, drowsiness, a drugged feeling, and
dry mouth.
Lorazepam: The potential side effects are dizziness, drowsiness, a drugged feeling, and some
potential for tolerance and withdrawal symptoms.
Diphenhydramine, hydroxyzine: The potential side effects are dizziness, drowsiness, a drugged
feeling, and dry mouth.
2.B. Other medication related risks:
Delay to Infusion: We will schedule the infusion as soon as possible. Patients on psychotropic
medications may continue them. Patients may experience worsening of their depressive
symptoms during this period and this will be discussed with all subjects as part of the consent
process.
Non-response: There is a chance that the medications and/or dosages used in this study will not
be helpful or that a participant may feel worse during participation in the study. Participants will be
encouraged to tell their doctor if they feel worse during the study.
Other Risks Associated with Antidepressant Use:
The Food and Drug Administration (FDA) has issued a public health advisory concerning a
possible link between worsening depression, and, in rare cases, suicidal thoughts or behavior in
adults younger than 25 years of age treated with certain antidepressant medications (including
those in this study). This FDA advisory will be discussed with all subjects as part of the consent
Protocol Summary Form
6598
Grunebaum, Michael
Page 27 of 31
process.
2.C. Risks from Intravenous Catheters. There is a small risk of infection and bleeding
associated with intravenous catheters, which are prevented by proper techniques. Placement of
IVs will be by a physician, nurse, or technician trained and certified in aseptic technique for
catheter placement to minimize this risk.
2.D. Blood Drawing: The risks associated with drawing blood are slight discomfort and

Protocol Summary Form
6598
Grunebaum, Michael
Page 23 of 26
occasional bruising. There is no risk of anemia in a physically healthy person with the amounts of
blood drawn in this study.
2.E. Interviews: Psychiatric interviews and neuropsychological testing can sometimes be
stressful, but some people find talking to a physician or psychologist helpful. The interviewers will
all be experienced personnel. The research team may request permission to record the interview
for teaching purposes with audiotape and/or videotape. In this event, a separate consent process
will occur for this.
2.F. Saliva sampling: This procedure has no significant risks other than minor inconvenience.
2.G. Pregnancy: Pregnancy is one of the study’s exclusion criteria and will be ascertained at
screening with a pregnancy test. Patients must agree at the time of consent to use an effective
form of birth control and to inform the treating psychiatrist in the event of pregnancy while in the
study. A pregnancy test will be repeated on the pre-infusion day. If a patient becomes pregnant
during the study, they will be withdrawn from research and treated clinically.
2. H. Electrocardiogram
An electrocardiogram has no serious risks. On rare occasions a rash may develop where the
electrodes are placed which usually resolves without treatment.
3. Data and Safety Monitoring Plan: The Principal Investigator will be responsible for monitoring
the safety and sound clinical care of all study participants through a weekly team meeting and as
needed.
3.a. Adverse events. Serious adverse events will be reported per regulatory requirements. Other
adverse events will be monitored using the SAFTEE-GI (17) and a weekly meeting of the research
team.
3.b. Data and Safety Monitoring Board
i) Membership: A Data Safety Monitoring Board (DSMB) will consist of three members, all
experienced psychiatric researchers in depressive disorders. None will be affiliated with the
research team conducting this project.
ii) Responsibilities: The initial tasks include review of the protocol and study forms documenting
adverse effects, laboratory results, and clinical research forms. If any modifications are indicated,
they will be instituted. Throughout the study, notification of any Serious Adverse Events (SAEs) as
Protocol Summary Form
6598
Grunebaum, Michael
Page 28 of 31
well as any investigator-initiated changes in the protocol will be submitted to the DSMB when they
are submitted to the IRB. Based on its review of the protocol, the DSMB will identify the data
parameters and format of the information to be regularly reported. The DSMB may at any time
request additional information from the Principal Investigator. The DSMB may monitor study
charts or delegate this task to the personnel of the New York State Psychiatric Institute IRB.
Other than SAEs, adverse events will be tabulated and submitted to the IRB and DSMB annually.
SAEs are also reviewed by the Incident Review Committee of the New York State Psychiatric
Institute. The DSMB will initially be given data blinded to treatment status but may request
unblinding if there is a safety concern.
Based on review of safety data, the DSMB will make recommendations concerning the conduct of
the study. These may include amending safety monitoring procedures, modifying the protocol or
consent, terminating the study or continuing the study as designed.

Protocol Summary Form
6598
Grunebaum, Michael
Page 24 of 26
iii) Initially, one DSMB member will review the study books of the first two patients to be enrolled
to make sure that all necessary forms are included and are being filled out correctly. In addition,
the DSMB will meet in person or by conference call after three and six months of enrollment and
then on a semi-annual basis but can determine that more frequent meetings are indicated.
Meetings:
iv) Reports: The discussions and decisions of the DSMB will be summarized in written reports
and provided to the NIMH Program Officer in annual reports.
v) HIPAA Procedures: This grant will go through Columbia University and will be conducted at
the New York State Psychiatric Institute and Columbia University Medical Center. All HIPAA
requirements will be followed including forms for patients to sign and receive a copy to keep as
part of the informed consent process.
 
Methods to Protect Confidentiality
Describe methods to protect confidentiality
Records will be kept in locked files and access will be allowed only to members of the research team or
institutional personnel as part of a routine audit. Research records, like other medical and clinical records,
will be kept confidential to the extent permitted by law. Once a patient enrolls in the project they are given a
code number for all subsequent computer data and/or lab forms. The code list and patient names as well
as all data are kept in locked files in locked offices with access limited to those directly responsible for
maintenance of these files by the research team. The data capture system we will use in this study,
StudyTRAX, has been used as a data repository for NIH sponsored projects at NYSPI and is HIPAA
compliant. Data sets are de-identified as defined in HIPAA 45 C.F.R. §164.514 (b)(2).
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
Subjects will receive a complete medical, neurological and psychiatric evaluation, results of which will be
communicated to them. Subjects are not expected to benefit directly from participation in this study,
however, they will be offered a total of six months of medication based treatment for depression.
Compensation and/or Reimbursement 
Will compensation or reimbursement for expenses be offered to subjects?
Yes

Protocol Summary Form
6598
Grunebaum, Michael
Page 25 of 26
Please describe and indicate total amount and schedule of payment(s). 
Include justification for compensation amounts and indicate if there are bonus payments.
We will give participants a modest inconvenience payment of $20 cash for each outpatient visit at which 
research data are collected, which we believe will not be coercive but will help recruitment and decrease 
attrition. Subjects will not receive payment for research assessments or procedures during the inpatient 
stay.
