This section is intended to provide a basic overview of the study including a description of its purpose, study procedures, 
and subject population.  The summary should provide a concise overview of the study for non-scientific and scientific 
members of the IRB.  Please avoid medical or technical terminology.  In general, the abstract of a grant does not provide 
a suitable lay summary.
Body dysmorphic disorder is a common condition characterized by symptoms of "imagined ugliness" with 
debilitating distress, checking and avoidance behaviors, and seeking unnecessary cosmetic medical 
procedures. Serotonin reuptake inhibitor medications and cognitive behavioral therapy helps some patients, 
but many do not benefit from existing treatments, and no medications are FDA-approved for this indication. 
Psilocybin is under development as a treatment of several psychiatric disorders, with placebo-controlled trial 
evidence of safety and prolonged efficacy for major depression when administered as a single dose with 
intensive support by a therapist on the day of administration. A single case report in body dysmorphic disorder 
suggests psilocybin might also have efficacy for this disorder.
In this proposed pilot study, up to 12 adults with body dysmorphic disorder that has not responded to at least 
one adequate trial of a serotonin reuptake inhibitor will be treated openly with a single oral dose of psilocybin. 
Procedures will follow those previously established in depression studies of psilocybin. Patients will receive 
intensive preparation and support from two therapists, including 8-9 hours accompanying the patient on the 
day of medication administration in the Biological Studies Unit. Follow-up visits to monitor safety and clinical 
outcome will be conducted at day 1, week1, and months 1, 2, and 3 post-administration. Resting state MRI will 
be conducted prior to and one day after psilocybin administration to assess the effect of medication on brain 
circuits.

Significance and Rationale

Protocol Summary Form
            
Rev. 10 – 11/08/2022
5
Body dysmorphic disorder (BDD) is a debilitating psychiatric disorder in which individuals are preoccupied with 
perceived defects of their appearance that are not noticeable or appear slight to others, causing significant 
distress and functional impairment (Phillips 2005). Compulsive checking may occur, and sufferers may seek 
out unnecessary or risky cosmetic procedures. Most common concerns in BDD involve skin, hair, and nose. 
BDD has a high prevalence in the general population of 1.7%-2.9% (Buhlman et al., 2010), but it is under-
studied. To date, there have only been controlled clinical trials to evaluate a single medication class – 
serotonin reuptake inhibitors (Phillips et al 2002, 2006; Hollander et al 1999) – and a single psychotherapy 
modality – cognitive-behavioral therapy (Wilhelm et al 2014). Although these treatments can be effective in 
many, they typically result in only partial symptom improvement and some individuals do not respond to 
either. There is a need for new intervention approaches.
The rationale for considering psilocybin as a potential treatment for BDD includes a case report (Hanes 2003), 
in which unsupervised use of psilocybin resulted in symptomatic improvement, as well as evidence for 
psilocybin efficacy in conditions that frequently co-occur or overlap with BDD, such as obsessive-compulsive 
disorder (Moreno et al, 2006) and major depressive disorder. The first step in further evaluation of the efficacy 
and safety of psilocybin for BDD is this proposed open trial, utilizing methods established in prior controlled 
trials of psilocybin for other disorders.
Psilocybin Background (see Studerus, et al., 2011, for a useful review)
"Magic mushrooms" have been used ceremonially and recreationally for thousands of years. psilocybin
produces an altered state of consciousness (ASC) similar to LSD, characterized by marked alterations in
perception, mood, and thought, including changes in the experience of time, space, perceptual 
hypersensitivity, illusions, and pseudohallucinations (i.e. hallucinations with intact reality testing and insight) 
intensification of affective responses, enhanced ability for introspection, regression to primitive and childlike 
thinking, and activation of vivid memory traces with pronounced emotional undertones (Fischer, 1971; Geyer 
and Vollenweider, 2008; Isbell, 1959; Leuner, 1962; Nichols and Chemel, 2006; Rümmele and Gnirss, 1961; 
Wolbach et al., 1962). These effects are similar to those of LSD, except of shorter duration (4-6 hours instead 
of 8-12 hours) and psilocybin tended to produce less anxiety, fewer panic reactions and affective disturbances, 
and milder vegetative side effects than LSD.
     Direct pharmacologic effects of psilocybin appear to occur through stimulation (agonism) of various
serotonin receptors, including 5-HT2A, 5-HT2B, 5-HT2C and 5-HT1A. The 5-HT2A receptor seems
particularly important as many, but not all of psilocybin's effects are blocked by 5-HT2A receptor antagonists. 
Serotonergic hallucinogens such as psilocybin are considered relatively safe physiologically and do not 
produce dependence (Johnson et al., 2008; Leuner, 1981; Nichols, 2004).
     Studerus et al., 2011, summarized patient experience, physiologic effects and follow-up from 8 studies in
which 110 non-psychiatrically ill volunteers were given oral psilocybin 2-28 mg (depending on the study) or
placebo and followed for up to 16 months. They report the following dose-dependent symptoms (i.e., the 
higher the dose, the greater the effect):
- Positive experienced derealization

- Positive experienced depersonalization
- Changed sense of time
- Positive mood
- Mania−like experience
- Anxious ego dissolution
- Negative experienced derealization
- Thought disorder
- Paranoia
- Loss of thought control
- Loss of body control
- Visionary restructuralization
- Elementary hall. & illusions
- Scenery hallucinations
- Synesthesiae (that is, stimulation of one sensory organ elicits a response from another sensory organ)
- Changed meaning of percepts
- Facilitated recollection
- Facilitated imagination
Psychological Adverse Events included:
- inactivation
- poor concentration
- tiredness
- dazed state
- introversion
- self-confidence (initially increased, later slightly decreased)
- heightened mood
- emotional excitation
- sensitivity
- slight increase in anger
- apprehension-anxiety
- depression
- dreaminess
Most of these adverse events returned to or toward baseline by 24 hours. The main exceptions were what 
they call "inactivation" and "tiredness" which remained nearly as high at 24 hours as at 3 hours. In addition, 
though closer to baseline, concentration remained decreased and dazed state and dreaminess were still 
increased at 24 hours. Griffith, et al. (2016) reports next day headache even with low dose psilocybin (1 mg or 
3 mg).

70 kg person (154 pounds)]):
- fatigue (60%)
- exhaustion (22.5%)
- headache, head pressure or facial pain (37.5%)
- lack of energy (22.5%)
- excessive sleep requirement (15%)
- fast exhaustibility (17.5%)

- heavy or tired legs (12.5%)
- sleeplessness (5%)
- abdominal pain (7.5%)
- throat pain/irritation (7.5%)
- diarrhea (7.5%)
Long-term Negative Effects
We found a single case report of persistent psychological effects ("flashbacks") following psilocybin use 
(Espiard et al., 2005). Griffiths et al. (2016), followed 51 depressed and/or anxious terminal cancer patients for 
six months after they received 30 mg or 22 mg of psilocybin, reporting “all . . . adverse events resolved fully by 
the end of the session” except headache which persisted into the next day in two subjects, and "There were 
no cases of hallucinogen [sic] persisting perception disorder or prolonged psychosis.".
     While not definitive, given there are hundreds of reported dosings of psilocybin plus unknown numbers of
recreational usages, a single case report suggests continuing symptoms long past the drug's active effects are
likely rare. Several authors point out that early reports of continuing flashbacks following uncontrolled use of 
hallucinogens mainly refer to LSD, not psilocybin, and did not address whether other drugs were also used or 
whether pre-existing psychiatric conditions that will be excluded in the present study were also present. Also, 
such uses were rarely closely monitored by a facilitator as will occur in the present study.
     We are not aware of a study comparing facilitator to no facilitator. Intuitively, it makes sense that having
someone present who might assist the individual in making sense of their experience might mitigate against
it being as negative an experience as it might otherwise be, and we are not aware of reports of "flash-backs"
or other late negative effects in individuals who used psilocybin in the presence of a trained facilitator.
Addiction Potential
As psilocybin is a Schedule I drug (meant to mean "no currently accepted medical use and a high potential
for abuse") it is reasonable to have concern that study participants will become addicted to psilocybin. Our
understanding is there is no documented case of an individual becoming addicted to "magic mushrooms" or
psilocybin. In fact, individuals who have used either magic mushrooms or psilocybin repeatedly space
their use out as if their repeat use is less than several months after a prior use, they achieve only a fraction of
the earlier effect. This also argues against there being addiction potential for this compound.

Rationale for the Psilocybin Doses use in this Study
Carhart-Harris, et al. (2016), suggested efficacy for depression with 10 and 25 mg and Griffiths, et al. (2016) 
found 20 and 30 mg doses to be effective for depression. Carhart-Harris reported 25 mg was well-tolerated 
with most adverse events being transient (1-3 hours) and mild, while Griffiths decreased their "high dose" 
from 30 mg to 22 mg because of poor tolerance of the 30 mg dose (vomiting); they reported 22 mg to be well 
tolerated with none of the adverse events requiring intervention beyond the supportive therapist. Both 
Carhart-Harris and Griffiths reported the only delayed (next day) adverse events were headaches lasting < 24 
hours. Personal communication with Carhart-Harris (2019), supported use of the 25 mg dose as optimal to 
maximize efficacy while minimizing risk of adverse events, based on his published studies and subsequent 
unpublished experience with psilocybin.

I attest to follow the COVID-19 Safety Guideline for Columbia Psychiatry and NYSPI Re-Entry outlined in the 
NYSPI Director’s June 1, 2020 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.
•
Clinical research teams will screen heir 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.
COVID testing: Depending on COVID conditions in the community, the participant and the two therapists 
scheduled to be with the participant during the psilocybin day may be tested at NY State Psychiatric Institute 
on the day before psilocybin dosing, to determine if any may currently be infected with the virus that causes 
COVID-19. The test involves collecting a sample by putting a cotton swab several inches into the nose. If the 
test shows that the participant or either therapist has COVID-19, your research treatment visit will be 
postponed.
Internet-based data collection or transmission will be conducted following HIPAA and NYSPI guidelines.
1. Visit 1 (Screening). A complete psychiatric and physical examination will be performed, including
Psychiatric, Medical and Social Histories, MINI Structured Psychiatric Interview, SCID-5 BDD module, Hamilton 
Rating Scale for Depression, Columbia Suicide Severity Rating Scale, and standard laboratory testing including 
EKG, urine for routine analysis, drugs of abuse and (if appropriate) pregnancy and blood for hematologies and 

Protocol Summary Form
            
Rev. 10 – 11/08/2022

chemistries including thyroid function. A physical examination will be performed at the screening or between 
screening and Visit 2 (Day -1), with results obtained before psilocybin administration day. 
Additional screening will specifically assess eligibility for the MRI portion of the study with the self-rated 
PhenX Toolkit Hand Dominance Measure and MRI Metal Screening Questionnaire. Contraindications to MRI 
scanning are:
•
Paramagnetic metallic implants or devices
•
Contraindicating magnetic resonance imaging or any other non-removable paramagnetic metal in the 
body (e.g., pacemaker, paramagnetic metallic prosthesis, surgical clips, shrapnel, necessity for constant 
medicinal patch, some tattoos)
•
Being unable to tolerate the scanning procedures (i.e., severe obesity, claustrophobia)
Patients with contraindicated metal or left-handedness will not be offered MRI participation but will complete 
all other parts of the protocol. 
Additional visits (V1a, V1b) will be scheduled as needed to follow up on any lab abnormalities and for patient 
to establish relationship with study therapist. 
Participants will be invited to bring to the screening a companion (friend/family member) whom they would 
like to support them through the study. Such a companion will be informed of their potential role and will be 
asked to sign a “caregiver” consent form at the Screening Visit. Caregivers will receive information about the 
signs of worsening of depression and suicide risk and ways to contact the study team if necessary. The 
caregiver will complete a questionnaire at screening, Week 3 and Week 12. 
2. Visit 2 (Baseline, Day -1). Eligibility and willingness to participate will be reassessed. At this visit, the patient 
meets with the therapist who describes what the experience might be like and how the therapist will handle 
any difficulties the patient may have with the experience. MRI-eligible subjects will complete acquisition of 
resting state fMRI. Subjects will also complete an inverted face computer task in which they will view an image 
of a face and then will be shown an image of two faces (one matching and one non-matching morphed face) 
and asked to select the matching face as rapidly and accurately as possible. The matching and non-matching 
faces will be presented either upright or inverted, in various combinations. This task assesses global vs. local 
visual processing, and it has previously been shown to be abnormal in BDD (Feusner, 2010).
3. Visit 3 (Psilocybin Day, Day 0). The next day, a study psychiatrist again assesses eligibility; those eligible and 
agreeable receive their dose of psilocybin (25 mg) and spend the next eight hours (longer if needed) with the 
two therapists; when deemed appropriate, the patient is accompanied home either by a person of their 
choosing or a staff member. The patient will be reminded that they should not drive or drink alcohol at least 
until after the end of Visit 4 (next day). Vital signs are taken prior to their dose of psilocybin and prior to 
leaving the clinic and a study psychiatrist evaluates prior to their departure for whether their condition 
requires them not to leave. In the latter case, they will either remain in the Biological Studies Unit (BSU) until

cleared by a study psychiatrist or admitted to 5-South inpatient service if they require additional observation 
overnight.
Psychological Approaches to Anxiety
•
During Visit 2 and prior to ingestion of psilocybin during Visit 3, explain anxiety, even fear, may occur
•
During Visit 2, train patient in relaxation and breathing techniques that may alleviate anxiety
•
On Visit 3, shortly after psilocybin ingestion, remind subject of possible anxiety reaction and that 
therapist will walk them through it should it occur
•
During Visit 3, if patient reports excessive anxiety or fear, walk them through relaxation and breathing 
techniques taught during Visit 2
•
Encourage exploration of psilocybin experience
•
Call M.D. if fear is not alleviated by the above   
Rescue Medications
•
Anxiety: Lorazepam or alprazolam
•
Psychosis: Risperidone
•
Headache: Acetaminophen
•
Symptomatic elevation in BP: Beta-blocker (e.g., propranolol)
•
Nausea/vomiting: Ice chips
Hospitalization if needed
•
Given prior experience with psilocybin treatment, the need for inpatient hospitalization appears 
unlikely
•
In the event that patients require hospitalization they may be admitted to NYSPI 5-South unit.
•
Prior to psilocybin dosing Dr. Mary Bongiovi will be contacted (email or text 917-301-1584) to ascertain
•
whether backup 5S inpatient bed at NYSPI will be available. In event of lack of availability for such a 
bed on 5S after it has been offered (e.g., unanticipated issue on inpatient unit) the NYPH. Emergency 
Room will serve as backup.
4. Visit 4 (Post-Psilocybin Day 1). The patient returns to the anxiety clinic and reports any experiences since
leaving the clinic as well as having blood, urine, and EKG tests. MRI eligible patients will have another resting 
state fMRI session, The inverted face task will be repeated.
5. Visits 5-8 (Post-Psilocybin Weeks 1-3 and 12). The patient returns 1, 2, 3 and 12 one week later for
standard evaluation of psychiatric symptoms, functioning and AE's. These visits may be conducted by phone or 
secure video.
6. Telephone visits (Weeks 6 & 9). The patient is contacted by telephone 6- and 9-weeks post-psilocybin
for standard evaluation of psychiatric symptoms and AE's.

7. Early Withdrawal Visit. Should the patient or study doctor decide to end the study visits prior to Week
12, if the patient agrees, all Visit 10 (Week 12) ratings including Independent Evaluation will be made.
Extra Visits
1. Extra visits (or in-person visits when phone visits are called for) will "kick in" if:
2. Patient reports on-going or intermittent negative effects, including but not limited to:
a. "Flash-backs"
b. Psychotic or quasi-psychotic (e.g., illusions, non-paranoid worries re. how others are viewing or 
treating them) experiences
3. Significant (e.g., > 25% increase in BDD-YBOCS) worsening from original severity.
4. Significant suicidality (e.g., patient reports suicidal thinking with any intent to act)
5. Physician's clinical judgment
Detailed Procedure for Staff Escort Home
In the event that it is deemed appropriate for a patient to return home following their psilocybin experience 
and said patient has not provided a responsible party to accompany him or her home, a staff member will 
accompany the individual from the BSU treatment room to the exterior door of their home. Transportation 
will be via a car service for which we will pay. The staff member will be instructed to contact the Anxiety 
Disorders Clinic doctor on call should he or she note grogginess or unsteady gait or other reasons to think the 
subject might have trouble being alone and the doctor will determine whether to have the staff member bring 
the subject back to NYSPI for further observation, erring on the side of further observation. Else, the staff 
member will allow the individual to enter their home and close the door, the staff member remaining outside 
and relieved of escort duties.

Define criteria that will be used to exit or drop subjects from the study and operationalize.  Indicate the time points when 
such criteria will be applied, and describe the rating instruments, parameters, and thresholds that will lead to a decision

to terminate a subject's participation and the role of the person who will make these determinations. Studies which 
include a medication taper and discontinuation may be asked to include an independent medical monitor (an MD not on 
the study team) who will aid the study team in determining whether study discontinuation is needed.   In addition, 
explain procedures for managing subjects who are withdrawn from the protocol.
For treatment studies: To minimize risks to subjects, operationalized drop-out criteria should be defined so that subjects 
who worsen, or in some cases, fail to improve, are removed from the study and offered standard care.  The threshold for 
drop-out should consider the level of risk associated with non-improvement for the specific disorder, the availability of 
alternatives, and the typical required duration of treatment.  For example, emergence of suicidal intent, or psychosis, 
should prompt immediate clinical evaluation and withdrawal from the study.
1. Patient withdraws consent
2. Study personnel determines it is not in the patient's best interest to continue in the study. 
3. Clinical worsening
4. At each assessment participants will be evaluated for clinical worsening, and any participant who 
reports symptomatic worsening (CGI Change Score >4) will be further evaluated for need for urgent 
clinical treatment. Further evaluation will include the Hamilton Depression Scale, the Columbia 
Suicide Severity Rating Scale (C-SSRS), and the Clinical Global Impression Change Scale, but the 
ultimate decision to provide or refer to non-study treatment will be based on clinical judgement, 
with reasoning documented in the chart. 
5. Any participant who evidences need for non-study clinical treatment before psilocybin 
administration will be removed from the study and offered appropriate referrals, including 
transitional treatment in the Anxiety Disorders Clinic, or being walked to the emergency room if 
indicated. After psilocybin administration, clinical deterioration will be treated the same way, 
except that patients will be permitted to continue participation in remaining study assessments.
6. Potential pregnancy: Participants who prior to dosing have a positive pregnancy test or report 
suspecting pregnancy will be removed from the study.  Participants who after dosing have a 
positive pregnancy test will be excluded from the repeat MRI but will be allowed to continue in 
study assessments of symptoms.  They will be offered assistance with obstetrical follow-up

Research involving participants who are in need of treatment invariably involves delay to care, and this delay is 
associated with risk.  Scheduling of procedures must be carefully organized to minimize delay.  Other delay must involve 
only that minimally necessary to accomplish the aims of the research while respecting subject well- being and safety. 
Describe the delay, by virtue of research participation in this study, before a participant can receive treatment of known 
efficacy or standard care routinely offered in the community.
Participants in the study will need to be free of SSRI medication for at least 2 weeks prior to psilocybin 
administration and for 3 weeks thereafter, so total delay to an established treatment will be 5 weeks. Patients 
who for clinical reasons need treatment intervention sooner will be offered established treatment. If patients 
need to restart SSRI’s prior to the psilocybin session, they will be excluded. If they restart after the session, the 
reason will be documented, and the patient will be followed until the end of study visit provided that 
informed consent is maintained.

"Risk" is a broad term used to convey the potential for harm, burden, and inconvenience related to research 
participation.  Use this section to provide a comprehensive description of foreseeable physical, psychological, social, 
interpersonal, and economic risks introduced by the research.  Include the source of the information.  Consider both the 
probability and magnitude of harm and its impact.  Describe the foreseeable harms associated with the research 
(untoward effects of a medication) and those related to delay to individualized treatment.  Include data from the 
literature, and local data, if available, on risk rates and subject experiences with research procedures. Describe 
procedures in place to minimize risk. In general, please create a numbered list of risks/categories of risk, and in general 
put the list in the order of significance or level of risk, the most significant risks should be listed first. 
1. BDD might not remit or may worsen
2. Psilocybin has not been extensively studied, so both short and especially long-term consequences of its 
use may not be known at present
3. Known psychological effects of psilocybin include:
a. Euphoric mood
b. Dissociative experience (i.e., feeling outside one's body or unreal, a distorted sense of time
c.
Hallucinations (which may persist for weeks after dosing)
d. Psychotic experience such as paranoia
e. Difficulty with cognition (e.g., trouble adding or solving puzzles)
f.
Disturbance in attention
g. Mood alteration
h. Inappropriate affect (e.g., crying when one is not sad or laughing when nothing odd occurred)
4. Known medical effects of psilocybin include:
a. clumsiness
b. feeling weak

Describe procedures for minimizing risks:
1. BDD might not remit - standard medication treatment, such as with an SSRI will be instituted and 
patient will be referred for CBT or other therapy as clinically indicated.
2. Psilocybin has not been systematically studied, so both short and especially long-term consequences of 
its use may not be known at present - while unknown risks cannot be minimized, we will minimize the 
likelihood of such risks occurring unnoticed during the study period by asking re AE's at every post-
psilocybin visit and encouraging patients to call between visits should any untoward events occur, 
whether they think they may be related or not.
3. Known psychologic effects of psilocybin include:
a. Euphoric mood - the risk of feeling too good is it can result in rash behavior, as in mania. We 
anticipate that if euphoria occurs, it will happen on the psilocybin day when the therapist and 
others are present to monitor and talk the patient down from an overly euphoric mood. As 
overly euphoric mood is a characteristic of bipolar illness, so to minimize risk the study excludes 
patients with known bipolar disorder. 
b. Dissociative experience (i.e., feeling outside one's body or unreal, a distorted sense of time) – 
We anticipate that if the patient has a dissociative experience, it will occur on the psilocybin 
day when the therapist will be present to "talk them down" and other clinicians will also be 
readily available.
c.
Hallucinations - as with b)
d. Psychotic experience such as paranoia - as with b); our anticipation is psychotic experiences will 
spontaneously remit within hours of the subject receiving psilocybin. If not, the on-call 
psychiatrist can determine whether to give an antipsychotic medication.
e. Difficulty with cognition (e.g., trouble adding or solving puzzles) - again, this will occur on the 
psilocybin day and will be minimized by therapist support, and it is anticipated to dissipate by 
the time the patient goes home, or at least by the next day. 
f.
Disturbance in attention - this is also anticipated to mainly occur on the day the patient receives 
psilocybin, but its impact on functioning will be monitored out to Week 12 using the SDS.
g. Mood alteration – mood will be monitored using the HAM-D-17 and the PANAS
h. Impaired Psychomotor skills - this will be monitored by clinical observation and is expected to 
resolve during the treatment day.
i.
Inappropriate affect (e.g., crying when one is not sad or laughing when nothing odd occurred) – 
this will be monitored by clinical observation and the PANAS and dealt with as part of the 
therapist's interaction with the patient.
4. Known medical effects of psilocybin:
a. Clumsiness - a staff member will remain with patient at all times ready to prevent falls as 
needed (e.g., traveling to and from the bathroom)
b. Feeling weak - ditto
c.
Headache - standard headache remedies (i.e., NSAID's)

d. Hyperreflexia - reassurance and waiting
e. Hyporeflexia – reassurance and waiting
f.
Elevated blood pressure - watchful waiting as to date, the blood pressure has not been 
documented to get to dangerous levels (i.e., systolic pressure may get to 160 mm Hg); as blood 
pressure rises typically last 1-3 hours, a short-acting blood pressure lowering medication such 
as nifedipine could be considered
g. Increased pupil size - keep in darkened room (this is the standard lighting in psilocybin rooms
h. Rapid heartbeat - watchful waiting as to date, fast heart rate has lasted 1-3 hours; propranolol 
could be used but to my knowledge no "rescue" med has been required to date.
i.
Tremor - this typically lasts 1-3 hours so should not require anything besides reassurance; if 
severe enough, do not allow hot liquids
j.
Vomiting - this is unusual and time limited; probably too short-lived for anti-emetic medication 
to help; could try ginger ale or ginger tea
5. Discomfort of repeated needle sticks and other procedures: experienced, trained phlebotomists will 
obtain blood
6. Time commitment to completing forms, and attending evaluation, treatment, and follow-up sessions - 
we will do everything we can to limit time spent; e.g., if patients must wait for their doctor, they will be 
instructed to complete their self-report forms
7. Psilocybin is not considered safe during pregnancy or breast-feeding, because such safety testing has 
not been done. Therefore, potential participants will be excluded if pregnant, breast feeding or 
planning to become pregnant during the next 3 months. A pregnancy test will be done at screening. 
Pregnancy tests will be repeated at least twice during the study (on the day prior to taking psilocybin, 
and on the day taking psilocybin). Participants will be cautioned that even if a pregnancy test is 
negative, they could still be pregnant, because these tests cannot detect very early pregnancies (that 
is, within the first few days). Participants will be excluded if they do not agree use an effective form of 
birth control before and throughout study participation. Methods of birth control considered to be 
effective include double barrier methods (condom plus spermicide, or diaphragm plus spermicide), 
birth control pills, birth control shots and intrauterine devices. Men who are sexually active will also be 
excluded if they do not agree to using adequate contraception. Female partners of men participating in 
this study should use one of the acceptable methods of contraception (contraception pills, intrauterine 
device, bilateral tubal occlusion).
8. To minimize the risk of MRI we will observe United States Food and Drug Administration (FDA) 
guidelines for magnet strength and exposure to radio waves. We will exclude people with magnetic 
metal in their body through careful review and checklist. Participants will be specifically warned about 
risks of a pacemaker or metal objects inside the body, as well as the need to remove all metal from 
their clothing and all metal objects from their pockets. Also, although there are no known risks to 
pregnancy, we will not scan someone who is pregnant, and women in childbearing years will take a 
pregnancy test just before each MRI scan.

In addition, and not specific to any one of the above, a physician will always be available should the therapist 
become uncomfortable, whether with physical reactions (such as elevated blood pressure) or behavior (e.g., 
belligerence) or reported symptoms (reports of psychotic symptoms or suicidality). The therapist's training will 
be to err on the side of calling the physician unnecessarily rather than allowing the patient's condition to 
worsen further. While our read of others' experiences with similar doses of psilocybin is situations requiring 
medical interventions are highly unlikely, we recognize it is important to be prepared for such an eventuality. I 
have not seen articles documenting the need for rescue medication so can only make the generic suggestion 
that for difficult psychiatric symptoms, one might first consider a short acting benzodiazepine, such as 
lorazepam, and then an antipsychotic medication, such as quetiapine. Medical symptoms would be 
counteracted using appropriate medications, e.g., nifedipine for hypertension. As the half-life of psilocybin 
and its first metabolite are a few hours it is not surprising that the adverse effects of psilocybin typically last 1-
3 hours, so it is likely that should rescue medication be needed it would only require short acting drugs; 
adverse events that continue into the next day are reported as having been mild (e.g., Hasler et al., 1997) 
while the only reported late appearing (i.e., not present acutely following psilocybin dose) adverse event is 
mild-moderate headache lasting < 24 hours.

Describe the data management plan and the methods you will employ to protect subject privacy and the confidentiality 
of research data.  The section should detail how information will be collected, recorded, coded, stored, transmitted, and 
as applicable, shared with other investigators so as to minimize risks related to breach of confidentiality.  Confirm that 
identifiers are removed, to the extent possible, from research data, and explain if there are links between subject identity 
and research data, or if the data are anonymous.  Also, indicate where the data are stored, who is responsible for data 
safekeeping, and who has access to subject identity and codes, if any, which cross-link research data and subject identity.  
Confirm that identifiable data are not collected, stored, or transmitted by mail, fax, on removable drives, laptops, or via 
the internet without proper protections, e.g. encryption.
Confidentiality will be maintained by keeping physical data in locked file cabinets. Any electronic data,
including laboratory results will be communicated within strict HIPAA rules. Methods by which confidentiality 
is protected include HIPAA-compliant videoconferencing and web-based platforms. Any data sent to the 
company will include initials, gender, marital status, SES and education and date of birth only without 
additional potential identifying information. Should it become necessary for the treating psychiatrist to 
contact the subject’s primary physician to obtain copies of their medical records or release our records to 
other providers, explicit written agreement for such record transfers will be obtained from the patient. Any 
electronic data stored at the Anxiety Disorders Clinic will be kept behind the NYSPI firewall with access only to 
authorized personnel by individual password. We will be applying for a certificate of confidentiality.

We will provide Compass with safety data from the Study, for storage by Compass on a central database. Such 
information shall be provided to Compass on a regular and on-going basis throughout the Study.  
Notwithstanding the foregoing, patients must be consented to have their data stored in this secure centralised 
database, maintained by Worldwide Clinical Trials (WCT). Only patients who consent to this process will have 
their personal data transferred. 
All types of adverse event will be promptly reported to Compass for use in the Compass/WCT safety database, 
they do however have different recording and reporting requirements, as set out below. 
For the purposes of reporting to the safety database, and subject to data protection requirements, we will 
promptly report to Compass all Serious Adverse Events (“SAEs”) regardless of the causal relationship to the 
Study Drug.  
Assessment of Seriousness 
For the purposes of the reporting of the adverse events to Compass, each adverse event will be assessed for 
its seriousness.  An SAE is any event that meets any of the following criteria:
•
Death
•
Life-threatening
•
Inpatient hospitalization or prolongation of existing hospitalization
•
Persistent or significant disability/incapacity
•
Congenital anomaly/birth defect in the offspring of a subject who received the study drug.
Other: Important medical events that may not result in death, be life-threatening, or require hospitalisation, 
may be considered an SAE when, based upon appropriate medical judgment, they may jeopardise the Subject 
and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. 
Examples of such events are:
•
Intensive treatment in an emergency room or at home for allergic bronchospasm
•
Blood dyscrasias or convulsions that do not result in inpatient hospitalisation
•
Development of drug dependency or drug abuse
Adverse Events of Special Interest 
For the purposes of the safety database, an adverse event of special interest (“AESI”) is an adverse event 
(serious or non-serious) of scientific and medical concern specific to the study drug, for which ongoing 
monitoring by the Clinical Investigator is required. Such adverse events may require further investigation to 
characterise and understand them. 

Protocol Summary Form
            
Rev. 10 – 11/08/2022
31
The following events will be reported as AESI:
•
Euphoric mood
•
Dissociative disorder
•
Hallucination
•
Psychotic disorder
•
Cognitive disorder
•
Disturbance in attention
•
Mood altered
•
Psychomotor skills impaired
•
Inappropriate affect
•
Overdose
•
Intentional product misuse
All AESIs will be followed until resolved or stable.
Reporting Adverse Events 
Each adverse event will be assessed to determine whether it should be classified as a SAE.  If the adverse 
event is considered serious, we will report this event in line with requirements of the study sponsor and the 
IRB. This may include completing a sponsor specific SAE reporting form, within 24 hours of learning about the 
event, regardless of causal relationship to the Study Drug. 
For the purposes of reporting to the safety database, these events will also be recorded on a specific Compass 
adverse event database CRF, within 24 hours of our becoming aware of them. This will also be the case for 
AESI. 
If we detect an SAE in a Subject after the last scheduled follow-up visit, and consider the SAE related or 
possibly related to the administration of the Study Drug, will report this to the sponsor. We will also report the 
event, on the Compass adverse event database CRF and send this in accordingly. 
We will report all other adverse events promptly to the Compass safety database after first becoming aware of 
such adverse event. These events will be reported and transferred on our Institution’s own study CRFs. 
All information about adverse events will be collected and once the relevant form is completed, it will be 
scanned and sent by email message or facsimile to WCT. The initial report should include the following 
information:
•

Fig 1. Reporting requirements 
Due to the limited safety data that have been collected formally for the Study Drug, all SAEs that are 
considered to be related will also be unexpected and therefore classified as Serious, Unexpected, Suspected 
Adverse Reactions (SUSARs). Classification of an SAE as a SUSAR will be determined on a case by case basis by 
WCT. Once an unexpected event has occurred, it will become expected in the future. The IBD will be updated 
annually to reflect changes in expected adverse events.  
GDPR
As owners of the external safety database, Compass Pathways are the “data controller” for this aspect of the 
research. WCT and the research team will act as “data processors”.  
Subjects will have the following rights regarding accessing their data stored in this database: 
1. To request to review their data held in the safety database.

2. To request for any inaccuracies to be corrected.
3. To raise objections to its content and to the continued processing of their data in this database.
4. To request to have their data removed from this database.
If any subject requests any of the above points regarding their safety data held in the safety database, we will 
notify Compass as soon as the request is made. Requests will be reviewed on a case-by-case basis and where 
Compass sees fit to action the request; they will work with us to resolve them as needed.

Statistical Analysis Plan 
The primary efficacy measure was BDD symptom severity, as measured by the BDD-
YBOCS, a clinician-rated scale (total score range: 0-48, with higher scores indicating 
greater severity). Response to treatment has been defined and validated as > 30% 
decrease in total score, and partial-to-full remission as total score <16 (Fernandez de la 
Cruz et al. 2019).  
 
Statistical Analyses: For YBOCS and other repeated outcome measures, repeated 
measures ANOVAs with Greenhouse-Geiser corrections will be conducted across time 
points from baseline to week 12 using SPSS Version 23.0 (IBM SPSS Statistics for 
Windows, Version 23.0. Armonk, NY: IBM Corp), with post hoc pairwise Bonferroni-
corrected comparisons. For the HRSD a paired samples t-test will be performed to 
compare baseline to week 12 scores.
