ESTIMATED DURATION OF THE STUDY 
 
Study enrollment will occur over approximately a two year period.  Completion of the entire protocol, including 
subject recruitment, study procedure execution, and statistical analysis is anticipated to take no longer than four 
years.  
 
Each subject will be enrolled for a 7 week period, including a screening phase. Study procedures involve weekly 
clinic visits as an outpatient. Approximately 72 patients will be randomly assigned to either 84 IU of oxytocin 
(equivalent to 42 IU BID), 168 IU of oxytocin (84 IU BID) or vehicle placebo. The doses of oxytocin are based 
upon previous studies in humans showing improvement in schizophrenia related changes in behavior and brain 
function (Kosfeld et al, 2005; Kirsch 2005; Heinrich M 2003). 
 
The total study duration for each individual subject will be approximately 7 weeks, which includes a 7-day 
screening period, a baseline (randomization) visit, and the six-week treatment phase. 
 
Participants will remain on their current antipsychotic medication and dose throughout the study.

LAY LANGUAGE SUMMARY OR SYNOPSIS (no more than one paragraph) 
 
The purpose of this study is to test whether or not people with schizophrenia feel improvement in their 
symptoms when oxytocin nasal spray is added to their current medications.  Volunteers will be randomly 
assigned to one of three groups; a higher dose group, a lower dose group, or a group who receives a nasal 
spray with no medication in it (placebo).  Volunteers will be asked questions about their mental and physical 
health as well as take several computer tests to track any changes over the 7 weeks of the study.

SPECIFIC AIMS 
 
The proposed study is a randomized, double-blind, placebo-controlled dose-ranging, pilot study intended to 
replicate and extend the promising results from an earlier proof of concept study testing intranasal oxytocin in 
schizophrenia. This second-stage pilot study will seek to obtain information not obtained in the limited proof-of-
concept study; specifically, the optimal dose of oxytocin for efficacy and tolerability, the time to optimal efficacy 
and the effects of longer term exposure (6 weeks) to daily intranasal oxytocin.  It is expected that the 
information obtained from this pilot study will provide indispensable information for the design and execution of 
future full scale parallel arm studies to test the efficacy and safety of intransal oxytocin.  It may also provide 
valuable information for other pilot studies that may test oxytocin in other clinical populations, and ultimately for 
the development of new treatment strategies for psychosis and other mental disorders based upon the use of 
oxytocin or oxytocin analogs.  
 
Specific Aim #1:To replicate the promising positive findings from the pilot study in a larger and more diverse 
sample of subjects recruited from more than one site.In the recent pilot-study mentioned, 80 IU of intranasal 
oxytocin significantly improved positive and negative symptoms of schizophrenia and short term memory 
recall. However that study was conducted in a small number of subjects using a crossover experimental 
design. These findings are very promising but need to be replicated with a larger number of subjects 
representing more than one recruitment site. 
 
Specific Aim #2: To investigate the efficacy and safety of higher doses of oxytocin.  The original study used 
80 IU of intranasal oxytocin and this was found to be well tolerated and effective. However the effect size in 
this study was moderate. It is possible that higher doses of oxytocin would produce stronger therapeutic 
effects; therefore, this study proposes to test a higher dose of oxytocin, 168 IU, in addition to the 
approximate dose tested in the pilot study.  
 
Specific Aim #3:Establish the time needed to reach peak efficacy.  Duration of treatment in the original study 
was three weeks, and significant therapeutic benefit was observed only at the three-week endpoint but not 
earlier. In the proposed study, subjects will receive study drug for 6 weeks and we expect that the size of the 
therapeutic benefit of oxytocin will increase from 3 to 6 weeks.   
 
Specific Aim # 4: Investigate the possible cognitive effects of intranasal oxytocin. In the pilot study, oxytocin 
significantly improved short term recall performance in the California Verbal Learning Test. This raises the 
possibility that chronic oxytocin will improve cognitive deficits associated with schizophrenia. This study will 
test this hypothesis using the Computerized Multiphasic Interactive Neurocognitive DualDisplayTM System 
(CMINDS®) and Mayer-Salovey-Caruso Emotional Intelligence Test: Managing Emotions (MSCEIT™ ME).  
 
Specific Aim #5:  To determine if daily intranasal oxytocin is sufficiently safe, feasible and acceptable to 
patients to warrant further clinical development. Information derived from this study will inform development 
of oxytocin not only for schizophrenia but other potential neuropsychiatric disorders. 
 
Specific Aim #6: The objective of the study is to compare the efficacy of intranasal oxytocin versus intranasal 
placebo to improve symptoms in schizophrenia patients who have residual symptoms despite being on 
adequate treatment with antipsychotic medication.  Improvement will be measured by total score in the 
Positive and Negative Syndrome Scale (PANSS). 
 
Specific Aim #7: To determine if oxytocin-induced enhancement of mu-rhythm suppression of ‘mirror’ neurons 
in schizophrenia patients can serve as a predictive biomarker of individual clinical response to this 
neurohormone. 
 
Secondary objectives include: 
 
To evaluate the efficacy of intranasal Oxytocin as measured by change in the total CGI-Severity and 
Improvement scores

blood tests, witnessed and reported adverse events 
 
To evaluate changes in ability to infer the mental state of others from emotion differentiation by their 
performance with the Penn Emotion Recognition Test (ER-40). 
 
To evaluate the possible correlation between the response to intranasal Oxytocin and biological 
markers, specifically endogenous oxytocin levels (tested via blood and saliva sample). Using saliva to 
test hormone levels has become a preferred method.  Many hormone levels can fluctuate throughout 
the day.  Using saliva allows for convenient specimen collection at multiple times (ie, pre and post 
dose). There is a believed correlation between the "bioavailable" (or active) amount of hormone in the 
blood and the levels found in saliva.  We will collect both blood and saliva samples to confirm or reject 
the proposed correlation which may lead to a more convenient way of collection in future trials. 
Determining hormone bioavailability is critical with hormones and saliva as the specimen medium is 
ideal for this.  
 
To assess the differential effect of oxytocin on early environment and social parameters based on 
scores on the Childhood Trauma Questionnaire (CTQ) and Experience Close Relationships (ECR). 
 
To detect and monitor any changes in sexual functioning as rated by the Arizona Sexual Experience 
Scale (ASEX) 
 
To determine if expected deficits in neural processing of socially relevant visual stimuli (mu-rhythm 
suppression of mirror neurons) in schizophrenia patients correlates with the severity or nature of their 
symptoms 
 
To determine if intranasal oxytocin can improve mu rhythm suppression in schizophrenia patients 
 
7. 
BACKGROUND AND SIGNIFICANCE 
 
Schizophrenia is a devastating chronic mental disorder reported to affect more than 2.4 million 
Americans (Kessler et al, 2005). Patients treated with even the best currently available antipsychotic 
medications typically continue to experience significant symptoms. Thus, there is a compelling need for novel 
treatments that are efficacious and safe. 
 
Oxytocin is a nine amino acid neuropeptide best known for its involvement in parturition and lactation. In 
addition to these well-established peripheral effects, there is a compelling body of converging evidence 
indicating that oxytocin plays a critical role in the regulation of a number of diverse centrally-mediated 
behavioral and cognitive processes that are highly relevant to schizophrenia (see Argiolas and Gessa 1990; 
McCarthy and Aaltemus 1997; Lee, Brady, Shapiro, Dorsa, & Koenig, 2005). Furthermore, several lines of 
research suggest that oxytocin receptors may be an important target for the development of novel treatments 
for schizophrenia. Oxytocin and its receptors exist in several areas of the brain which have been heavily 
implicated in the pathophysiology of schizophrenia, such as the nucleus accumbens and the hippocampus 
(van Leeuwen, van Heerikhuize, van der Meulen, &Wolters, 1985).  Oxytocin administered peripherally inhibits 
dopamine transmission in the mesolimbic pathway (Sarnyai et al, 1990). Moreover, antipsychotics have been 
found to elevate the secretion of oxytocin in rats (Uvnas-Moberg, Alster, &Svensson, 1992), suggesting that 
endogenous oxytocin may play a role in the therapeutic effects of antipsychotic drugs. 
 
These findings raise the possibility that exogenous oxytocin may have therapeutic potential as an 
antipsychotic drug.  The first direct preclinical proof-of-principal test of this notion was conducted by Feifel et 
al. (1999), who measured the effects of oxytocin on prepulse inhibition (PPI) in rats.  In that study, oxytocin 
administered subcutaneously in male rats produced a robust antipsychotic-like reversal of PPI deficits induced 
by amphetamine and the NMDA antagonist, MK801, an analog of PCP. This pattern of the reversal of drug-

 
 
Biomedical IRB Application Instructions 
Page 5 
induced PPI deficits is consistent with the activity of atypical antipsychotics (Geyer, 2001).  Since then, other 
investigators have reported findings supporting an antipsychotic role for oxytocin. Lee et al. (2005) found that 
centrally administered oxytocin ameliorated chronic PCP-induced behavioral withdrawal, an established 
animal model for negative symptoms of schizophrenia. Caldwell et al. (2009) found that mice genetically 
lacking oxytocin were more sensitive to PCP-induced PPI disruption. Additionally, Feifel et al (in preparation) 
recently found that subcutaneous oxytocin increased PPI in rats with naturally low PPI (see Preliminary 
Findings). 
Studies in humans provide further support for the contention that oxytocin may have antipsychotic 
properties. Schizophrenia patients have been found to have disturbed oxytocinergic function (Linkowsi et al. 
1984; Beckmann et al., 1985; Legros et al., 1992; Mai et al., 1993; but see Glovinshy et al., 1994).   In 
addition, two small and uncontrolled studies conducted in Russia evaluated the effect of intravenous oxytocin 
in schizophrenia and found promising results suggesting that it may reduce some symptoms of this disorder 
(Bujanow, 1974; Bahkarev et al., 1984). 
Recent research has shown that neuropeptides such as oxytocin cross the blood-brain barrier after 
intranasal administration (Born, 2002), providing a useful way of studying the central nervous system effects of 
neuropeptides like oxytocin that might otherwise not enter the CNS. Several studies have demonstrated CNS 
behavioral and brain imaging effects following intranasal administration of oxytocin (See MacDonald and 
MacDonald, 2010 for review; Garner et al. 2010) Oxytocin is commonly administered intravenously (Pitcocin 
®, Novartis) to stimulate parturition and an intranasal formulation of oxytocin (Syntocin®, Novartis) was 
approved by the FDA as a treatment for lactation aid. Though no longer available commercially in the U.S., 
this intranasal product remains available in other countries and has been used in a significant number of 
recent human studies (see MacDonald and MacDonald, 2010). Intranasal oxytocin doses ranging up to 320 
IU/day have been shown to be safe and highly tolerated (Epperson, 1996; Kosfeld et al., 2005). In a recent 
landmark study, Kosfeld et al. (2005) demonstrated that oxytocin administered intranasally to healthy human 
subjects in a double blind, placebo-controlled study increased levels of trust. Furthermore, it has been shown 
that intranasal oxytocin reduced activation of brain circuits involved in fear in human subjects (Kirsh et al, 
2005; Gamer et al, 2010) suggesting that intranasal oxytocin may reduce paranoia.  
Recently, Feifel et al. (2010) conducted a small proof-of-concept, randomized, double blind, placebo-
controlled crossover study comparing intranasal oxytocin to intranasal placebo added to stable doses of 
antipsychotic medication in patients with schizophrenia and found that oxytocin significantly reduced psychosis 
and improved short-term memory compared to placebo  (see Preliminary Findings).  This finding supports the 
notion that oxytocin may be a novel therapy for schizophrenia. This application proposes a pilot clinical trial 
that will extend the findings of the initial study and provide critical information for planning a subsequent 
definitive clinical trial.   
            Treatment for schizophrenia and related psychotic disorders is at an impasse. Recent studies have 
revealed that the advantage of second generation (atypical) antipsychotic over first generation (typical) 
antipsychotics, once thought to be substantial, is limited or non-existent. Thus treatments for this disorder have 
made little gains in the five decades since chlorpromazine was approved as the first antipsychotic. While 
currently available antipsychotics produce important improvement in symptoms of schizophrenia and related 
disorders, few patients experience a total remission of symptoms and a large proportion are left with 
debilitating residual symptoms. Thus, positive findings emanating from this study investigating effects of 
intranasal oxytocin as augmentation to antipsychotic drugs will have a significant impact in a number of ways, 
not least of which will be generation of strong interest in development of new compounds targeting the 
oxytocin system. 
           
Mu rhythm suppression is a candidate biomarker in schizophrenia: Biological motion as depicted in point 
light animations is a well-studied construct in cognitive neuroscience, where videos are created by filming a 
person in the dark with lights on major body joints, while performing a repetitive motion such as walking or 
jumping. These displays provide sparse visual input that requires “filling-in” to recover object information to 
identify the kind of motion being produced (e.g., walking, jumping, dancing) (Keri, et al, 2009). It has been 
suggested that neural processing of biological motion is an evolutionarily conserved mechanism that plays a 
fundamental role in social adaptation (Keri, et al, 2009). A number of studies have associated biological motion 
with neural activity in the mu (8-13Hz) range (Perry, et al, 2010) over the right sensorimotor cortex , and are 

 
 
Biomedical IRB Application Instructions 
Page 6 
thought to index the activity of ‘mirror’ neurons. Mu rhythms, measured from this brain region show reliable, 
dose dependent, suppression when the subject perceives biological motion (but not non-biological motion). 
Thus, mu wave suppression is an easily quantifiable operational measure of the neural processing of 
biological motion. In a recently published study conducted in Dr. Cadenhead’s laboratory, the applicant 
showed that neural mu wave suppression induced by biological motion is impaired in first-episode of psychosis 
subjects, and that the neural impairment is inversely correlated with negative symptoms and social adjustment, 
providing construct validity for the mu suppression paradigm as an operational measure of social cognition in 
patients with psychosis (Singh, et,al, 2010). 
                   Given OT’s strong implication in social perception, it would be reasonable to expect that 
exogenous OT affects mu wave suppression in the context of biological motion. This has been in fact, 
confirmed in a recent study by Keri et al. using a well-established paradigm of biological motion similar to that 
used by our group. Keri et al, demonstrated that intranasal OT significantly enhanced detection of biological 
motion (human form) but not non-biological motion (rotating circle) compared to intranasal placebo. Taken 
together, the applicant’s study and that by Keri et al, demonstrate that patients with psychosis have impaired 
biological motion induced mu suppression compared to normal subjects and that intranasal OT enhances this 
neural process in normal subjects. It is reasonable to expect that intranasal oxytocin will improve mu 
suppression in schizophrenia patients and we expect to demonstrate this. We also expect to find that subjects 
with the greatest enhancement in mu suppression are more likely to experience clinical improvement in 
response to 6-weeks of oxytocin treatment. 
 
Hypothesis:  We hypothesize that augmentation of antipsychotics with intranasal oxytocin will significantly 
improve psychopathology ratings as compared to placebo and an improvement in certain cognitive functions 
may be also observed.

PROGRESS REPORT 
 
Oxytocin is a peptide neurohormone that has demonstrated effects on brain pathways and on behaviors 
relevant to schizophrenia. Recent studies demonstrate that oxytocin has robust antipsychotic-like effects in 
animal models predictive for antipsychotic efficacy (Feifel et al, 1999; Lee et al, 2005). Small uncontrolled 
studies conducted found that oxytocin produced antipsychotic effects in schizophrenia patients (Bujanow 
1974; Bahkarev et al. 1984). Intranasal oxytocin is commercially available as a lactation aid and has a good 
safety and tolerability profile (see Risk Section of this research plan). Recently, Kosfeld et al (2005) reported 
that oxytocin administered intranasally, a route of administration thought to allow good access to the CNS for 
peptides like oxytocin, significantly increased trust in healthy subjects, a finding which may have relevance to 
symptoms seen in schizophrenia, such as paranoia. To date no randomized, placebo-controlled study of the 
efficacy of has been conducted to investigate the efficacy of oxytocin for symptoms of schizophrenia. The 
objective of the study is to compare the efficacy of intranasal oxytocin versus intranasal placebo to improve 
symptoms in schizophrenia patients who have residual symptoms despite being on adequate treatment with 
antipsychotic medication. 
 
The Principal Investigator examined the antipsychotic potential of oxytocin in an animal model of 
schizophrenia that has good predictive validity for drugs with antipsychotic efficacy based upon prepulse 
inhibition (PPI) of the startle reflex. PPI is a measure of sensorimotor gating.  PPI deficits are well documented 
in schizophrenia patients and are thought to reflect core dysregulation in circuits mediating sensorimotor 
gating and that are implicated in the pathophysiology of schizophrenia.  That study demonstrated that 
oxytocin, administered peripherally in male rats produced a robust antipsychotic-like reversal of PPI deficits 
induced by amphetamine and the PCP analog, MK801 (Feifel et al 1999). This profile of effects is most 
consistent with atypical antipsychotics (Geyer 2001).  In addition, a recent study showed that centrally 
administered oxytocin ameliorated chronic PCP induced behavioral withdrawal (Lee et al, 2005), an 
established animal model for negative symptoms of schizophrenia. 
 
A metaanalysis by Sprong et al. (2007) indicated that participants with schizophrenia perform well below 
healthy controls in tests of “theory of mind”. According to these authors, “theory of mind” refers to the cognitive

abilityto attribute mental states to people which helps a person explain and predict behaviors of others.  
Domes et al (2006) found that oxytocin improved the ability to infer the mental state of others from eye region 
cues by testing their performance on the RMET.  In addition, the Penn Emotion Recognition Test - 40 is an 
affective picture test that determines the subject’s ability to infer another person’s internal state from subtle 
affective facial expressions (Sachs et al 2004). This test has been incorporated into the current project as a 
secondary measure to investigate whether oxytocin may improve the ability of patients with schizophrenia to 
read the emotions of others.

RESEARCH DESIGN AND METHODS 
 
OVERVIEW: 
 
The proposed study is a randomized, double-blind, placebo-controlled study of the value of adjunctive 
intranasal oxytocin added to existing antipsychotic treatment compared with adjunctive placebo in subjects 
with schizophrenia. Enrolled subjects will be randomized and receive 6 weeks of treatment with one of the 
following adjunctives to a stable antipsychotic regimen: 1) intranasal oxytocin (84 IU/day), intranasal oxytocin 
(168 IU/day) or intranasal placebo.  The study will be conducted over 2 years. Approximately seventy-one 
subjects will be entered into the study, on average 35/36 at each site each year.  
 
PRIMARY OUTCOME MEASURE: 
Positive and Negative Syndrome Scale (PANSS):  The three subscales of the PANSS include the Positive 
scale (7 items), the Negative scale (7 items), and the General Psychopathology scale (16 items).  The total 
PANSS score is the sum of all 30 items of which each item is scored on a 1-7 rating system (7 indicating the 
worst symptoms).  The items on the PANSS focus on symptoms that are common in patients with psychotic 
disorders and include hallucinations, delusions and disorganization as well as mood disturbances. 
 
SECONDARY OUTCOME MEASURES WILL INCLUDE: 
Global Assessment of Functioning (GAF):  The GAF considers psychological, social, and occupational 
functioning on a hypothetical continuum of mental health illness.  Scores on the GAF range from 1 (extremely 
severe) to 100 (superior functioning). 
 
Clinical Global Impression-Severity of Illness (CGI-S):  The CGI-S is used to evaluate changes in overall 
severity of illness.  Scores range from 1 (not at all) to 7 (among the most extremely ill). 
 
Clinical Global Impression-Global Improvement (CGI-I):  The CGI-I is a global assessment to evaluate the 
subject’s improvement or worsening from baseline.  Scores on the CGI-I scale range from 1 (very much 
improved) to 7 (very much worse) 
 
Calgary Depression Scale for Schizophrenia (CDSS) is a ten item diagnostic questionnaire intended to assess 
the severity of depression symptoms experienced by a given patient.  The CDSS will be administered by a 
trained and qualified rater at each scheduled study visit. 
 
Hamilton-Anxiety Scale (HAM-A):  The HAM-A is a clinician administered scale for the evaluation of anxiety 
symptoms.  The HAM-A consists of 14 items of which each item is scored 0 (not present) to 4 (very severe). 

 
 
Biomedical IRB Application Instructions 
Page 8 
 
Paranoid Thought Scale (PTS): The PTS is a self-rated scale to assess current paranoia symptoms.  The PTS 
consists of 32 items that the subject rates from 1 (not at all) to 5 (totally).  
 
Treatment Satisfaction Questionnaire for Medication (TSQM): This is a very short questionnaire asking 
patients about how satisfied they were with the ease, timing, etc. of the study medication giving a good 
indication of adherence (Atkinson et al, 2004). 
Childhood Trauma Questionnaire (CTQ):  A validated measure of adverse early experiences characterized on 
a measure of Anxiety Sensitivity Index and retrospective childhood maltreatmentA 5-point frequency of 
occurrence scale is utilized: (1) never true, (2) rarely true, (3) sometimes true, (4) often true, and (5) very often 
true. Each subscale score ranges from 5 (no history of abuse or neglect) to 25 (very extreme history of abuse 
and neglect). 
 
Experience Close Relationships (ECR): The ECR is a self-rated questionnaire designed to assess individual 
differences with respect to attachment-related anxiety (i.e., the extent to which people are insecure vs. secure 
about the extent to which their partner's availability and responsiveness) and attachment-related avoidance 
(i.e., the extent to which people are uncomfortable being close to others vs. secure depending on others) 
(Fraley, R. C., Waller, N. G., & Brennan, K. A., 2000). 
 
Arizona Sexual Experience Scale (ASEX): The ASEX is a self-rated scale to assess sexual functioning.  The 
ASEX consists of 5 items that the subject will rate from 1 (Extremely strong, easily, or satisfying) to 6 (Absent 
or never) based on how he/she feels at the time. 
 
Social Phobia Inventory (SPIN):  The SPIN is a patient self-report scale that measures the degree of social 
phobia in a variety of different social situations 
 
Penn Emotion Recognition Test (ER40):  The ER-40 is a computerized emotion discrimination test presenting 
40 color photographs of evoked happy, sad, anger, fear and neutral expressions balanced for poser gender 
and ethnicity. 
 
The CMINDS® Computer Battery consists of the following: 
Please note: The CMINDS ® consists of “construct-equivalent computerized versions of the neurocognitive 
assessment instruments constituting the MATRICSTM Consensus Cognitive Battery (MCCBTM)” (O’Halloran et 
al. 2007). The CMINDS® assessments achieved identical face validity and high concurrent validity with 
traditional paper versions of the MATRICSTM Consensus Cognitive Battery (MCCBTM) (refs from above). Each

Mu wave suppression paradigm: If subjects agree to participate in this sub-study, the informed consent for 
EEG collection will be obtained prior to any EEG procedures. EEG waves will be recorded over 32-sites using 
a standard 32-electrode cap with the Biosemi system (9), while subjects are watching 60-80 second videos. 
The videos will consist of experimental conditions (point light animations of biological and non-biological 
motion, scrambled condition) and baseline condition (2 moving balls). All videos will be presented twice, using 
Presentation software (10). Data from both trials will be combined prior to analysis. Filters will be set to

microvolt deviations). Data will only be analyzed if there is at least 2 minutes of clean EEG per condition. For 
each segment, integrated power in the 8–13 Hz range will be computed using a Fast Fourier Transform. Mu 
suppression will be calculated for central (C3, Cz and C4) and occipital (O1 and O2) sites using the equation: 
Mu suppression = log10 (mu power of experimental condition/ mu power of ball condition). Occipital site 
electrical discharges will be recorded, integrated for power and compared between groups to determine if 
posterior alpha activity is causing differences across conditions.

aScreening procedures can be done over a week period if needed to complete all procedures such as 
confirmation of diagnosis. The screening and baseline visits can occur on the same day. 
 
b In addition to Visit 1, an optional urine drug screen or blood chemistry may be performed at any point during 
the study at the discretion of the Principal Investigator or study coordinators if it is suspected the subject is not 
abstaining from illegal substances or have general health concerns. 
 
cPremenopausal women will be queried regarding their menstrual cycles and data correlated with clinical 
findings.Patients are instructed to use a medically accepted form of birth control through their study 
participation, and are also questioned about their birth control method at each visit. If a pregnancy is 
suspected at any time during the study, the patient will be asked to complete a urine pregnancy test. 
 
d Basic Metabolic Panel includes Glucose, BUN, Creatinine, Bicarbonate, Chloride, Sodium, Potassium,  
Calcium, osmolality 
 
eOxytocin Levels will be collected via saliva and blood draw twice during the Baseline Visit.  One blood draw 
and passive drool will be collected at the beginning of the visit (pre-dose) and a second blood draw and 
passive drool collection will be taken 30 minutes after the in-clinic dose.  The third Oxytocin level will be taken 
at the patient’s last visit (either Visit 8 at the conclusion of the protocol or the Early Termination visit). 
f PANSS must be done at baseline, but it may be completed at screening in addition at the discretion of the  
 investigator if he feels that the subject may not met entry criteria 
 
gThe CGI-S will be completed twice at the Baseline Visit, once prior to dosing and a second time at least 50 
minutes after the in-clinic dose of the study drug or placebo.

h Practice improvement is expected with repetition of some MATRICS tests. While the parallel group design 
will determine any improvement beyond the practice effect, neuropsychologists Richard Keefe and Philip 
Harvey have pointed out the majority of practice effect occurs between the first and second administrations of 
the MATRICS battery (personal communications). This finding by Keefe and Harvey regarding paper versions 
of the MATRICSTM should translate to the computerized versions of the CMINDS® as O’Halloran et al. (2007) 
found that standard paper administration versions and computerized administration versions of neurocognitive 
assessment instruments are substantially equivalent. These computerized versions yielded highly equivalent 
measures of absolute agreement throughout all the test batteries when compared to the standard paper 
versions.The group comparison will be between baseline (after the majority of practice effect has occurred) 
and 6 weeks.  While this strategy may miss transient improvement between these timepoints it will decrease 
the practice effect. Transient improvements in cognition are not clinically meaningful.  
 
iAll patient-rated scales except the ASEX will also be given 50 minutes after the in-clinic dose at the Baseline 
Visit. 
 
jA Mid-Week Safety Call to Study Site - The subject will be instructed to contact study staff on day 3 or day 4 
of taking study drug.  This call will be a brief open ended question and answer discussion to find out the 
subject’s experiences with the study medication over the past few days and answer any questions that may 
arise.  
kA challenge dose will be administered between screening EEG paradigms. This dose will only be 
administered after all other inclusion/exclusion criteria have been verified. All subjects will receive 24IU as a 
challenge dose.

Follow Up Call 
The volunteer will be asked to contact the study site one week after the last study drug dose to report taking 
any new medications or any unusual experiences since stopping the study drug. 
 
Administration and dispensing of the study medication: 
Except the one time challenge dose, this is a double-blind study, participants will be randomized to receive 
one of three possible intranasal study medications adjunctive to their antipsychotics: oxytocin 84 IU, oxytocin 
168 IU or placebo (vehicle without oxytocin). Randomization will be performed stratifying gender groups, type 
of antipsychotic (typical versus atypical) and severity of symptoms based upon PANSS score (<90 versus >90) 
so that gender, symptom severity and antipsychotic type are distributed relatively evenly across treatment 
groups.  Bottles containing placebo or two different concentrations of oxytocin will be formulated (See Study 
Drug Formulation below) so that the concentration of oxytocin in the high dose (168 IU) will be double that of 
the low dose (84 IU). All subjects will be instructed to spray 7 pumps of the spray bottle (one in each nostril, 
alternating nostrils) to achieve correct dose in the morning and again in the afternoon.  Subjects will be given 
enough study drug at the time of the visit to last until the next visit with extra to cover approximately three 
additional days.  Each pump bottle has 5 ml (300 IU) which is enough for 2.5 days of study drug.  Therefore, 
subjects will be given one spray bottle supply at the time of each visit. The weight of each bottle will be 
recorded prior to dispensing. After all procedures are performed on baseline visit and study drug is randomly 
assigned, a dose of the study drug will be taken at the study site, in the presence of a staff member to insure 
correct administration. 
 
Study Drug Compliance 
1. 
Subjects will be instructed on proper use of the nasal device from study staff. 
2. 
Subjects will be given a diary card by the study staff to mark each use of the study drug in between site 
visits to the study site.  This is to help subjects track study drug use.  Subjects will be instructed to return 
study drug nasal spray bottles, used or unused, to the site at each visit along with the diary card. 
3. 
Each bottle will re-weighed after return to estimate the amount of fluid remaining 
 
STUDY DRUG: 
Intranasal oxytocin is FDA approved as a lactation aid and was commercially marketed (Syntocinon®, 
Novartis) in the US up to the 1990’s.  It continues to be marketed commercially by Novartis in Europe and 
elsewhere.  Oxytocin powder (Pictocin, Novartis) is readily available in the US and is used for intravenous

administration as a paruition stimulant in pregnant women.  Both intravenous and intranasal oxytocin are well 
tolerated and safe (Hoover RT 1971) (see risk section of this Research Plan). 
This study will use oxytocin powder supplied by Spectrum Laboratories and UCSD Investigational Drug 
Service (IDS) will make formulate both the Oxytocin and Placebo.

STATISTICAL CONSIDERATION 
  
Our primary analysis will be the comparison of subjects on oxytocin with subjects on placebo using a mixed 
model repeated measures analysis (MMRM). If this comparison is statistically significant then we use a linear 
contrast to investigate the dose-response between 84 IU (42 IU bid) and 168 IU (84 IU bid). We also have 
introduced an adaptive design that is consistent with FDA guidance for phase 2 studies when dosing groups 
are unclear (2010).  
Sample Size Calculation. The primary efficacy measure will be change in PANSS total score from baseline to 
each visit. Based upon a preceding proof-of-concept study (Feifel et al. Biological Psychiatry, in press) with 
effect sizes (cross-over design) range from .40 to .53. An estimated sample size of 24 in the placebo group 
and 48 in the oxytocin group (24 in each dose group) is required to achieve 85% power to detect an effect size 
of 0.3 for time-averaged main treatment effect (Cohen’s d for standardized mean difference between oxytocin 
and placebo treatment groups) using 6 repeated measurements having a AR(1) (first order autoregressive) 
covariance structures and assuming the correlation between observations on the same subject is 0.5, and the 
alpha level (Type I error rate) is 0.05 in a 2-sided test (Hintze, 2008). If we ignore the repeated measures 
design, an effect size of 0.5 will be detected with the same alpha and beta for the same sample size of 80 
patients in the ratio of 2:1 for oxytocin:placebo. 
The proposed sample size includes considerations for a single pre-specified, planned interim analysis for futility 
stopping based on conditional power (CP) (stochastic curtailing method) (Halperin et al., 1982; Lan et al., 1982) 
or an equivalent stopping boundary on interim Z-test value (B-value) (Lan and Witts, 1988). This interim futility 
analysis will be performed and reviewed by an external statistical consultant Cynthia Siu, PhD when 50% of the 
enrolled patients complete 6 weeks of follow-up. The adjusted critical value for an overall alpha of 0.05 (2-sided) 
in the final analysis is 0.0515 with resulting power 84.6% to detect a specified effect size of 0.3 or greater with 80 
patients in the ratio of 2:1 for oxytocin:placebo (See Interim Analysis Plan below).  
 
Futility Interim Analysis Plan.  This randomized, double-blind study adopts an adaptive design with a single 
pre-specified, planned, unblinded interim analysis for futility stopping based on conditional power (CP) 
(stochastic curtailing method) (Halperin et al., 1982; Lan et al., 1982) or an equivalent stopping boundary on 
interim Z-test value (B-value) (Lan and Witts, 1988). The purposes of this formal interim analysis are to assess 
CP levels which are the probability of reaching statistically significant treatment difference at study end given 
the interim results. To avoid inflation of Type I error, no early stopping for efficacy is planned in this study. The 
unblinded data will be only available to external statistician Dr. Siu and not the PIs or other study staff.   

 
 
Biomedical IRB Application Instructions 
Page 16 
 
It is well known that futility termination will reduce the Type I error rate (alpha) and inflate the Type II error rate 
(beta =1 minus power of the test), with the level of beta inflation bounded by PL0 , the probability of stopping for 
futility under the null hypothesis of no treatment effect (Lan et al., 1982; Lachin 2005). In order to maintain the 
design Type I error rate (alpha) at 5% and power close to 85%, we use an iterative procedure to determine the 
CP utility boundary values and the adjusted Z-test critical value in the final analysis, with 60% (PL0) chance of 
stopping for futility under the null hypothesis. This provides: 1) a CP futility stopping boundary value equal to 
0.3 at 50% enrollment (i.e. stop the trial if CP observed < 0.3) under the original design assumption (see 
Sample Size Calculation), 2) an adjusted Z-test critical value of 1.947 (ZF) for declaring significant treatment 
effect in the final analysis (or P<0.0515), and 3) an overall power of 84.6%, i.e. 15.4% overall Type II error rate 
with 3.1% false negative error rate at interim look and 12.3% probability of continuing the trial and failing to 
reject the null hypothesis (false negative error rate) at study end. 
 
In summary, we provide the following futility stopping rule for assessing interim results at 50% enrollment: 
1. A recommendation to stop the trial for futility if CP value for comparing combined oxytocin vs. placebo 
(i.e. the probability that final study results will be statistically significant given interim data) is less than 
30% under the original design assumption. An equivalent boundary for interim Z-test value is 0.253 
(interim P>0.800), interim B-value < 0.179, or if equivalently interim drift parameter estimate < 0.358. 
a.     If futility stopping criteria are met for the combined oxytocin group, we will examine CP and interim 
Z-test value for each dose (vs. placebo) to check if both dose groups meet a similar stopping criterion 
CP <0.3 (or P>0.800) for an overall alpha of 5% and an adjusted power of 80%. 
b.     In case of dropping only 1 dose arm and reallocation of remaining subjects to another arm we will 
use a fixed weighted Z-test method to protect the Type 1 error (Cui et al., 1999; Lan et al., 2005). 
 
2. To declare the treatment effect significant if p-value computed at study end (N=72) is less than 0.0515.  
 
This futility interim monitoring plan will include a vigorous data quality control to ensure successful signal 
detection in potential treatment effects. In addition to verifying validity of study design assumptions using 
the unblinded interim data, we will perform blinded, ongoing assessments of inconsistencies in the 
efficacy outcome measures, inter-relationships between efficacy variables, missing data patterns, and will 
implement a data management plan that has real-time capability to detect, query, and address data 
issues in the study.  
 
Analysis Methods: The primary population for efficacy analyses includes all randomized subjects based on the 
intention-to-treat principle. The population for safety analyses will include all subjects who receive at least one 
dose of study medication. In the primary analysis, we test the hypothesis of difference in PANSS total change 
score (Week 6) between the combined oxytocin and placebo groups with adjustment for baseline score using a 
likelihood-based mixed-effects model for longitudinal data analysis (MMRM LDA) (Fitzmaurice and Ware, 2004). 
The MMRM LDA model can accommodate incomplete data under the assumption of ignorable attrition (see 
below under Missing Data). The same MMRM LDA model will be applied to evaluate the dose-response 
relationship using a linear contrast for the placebo and oxytocin dose groups, comparisons of treatment groups 
over time using treatment-by-visit (categorical visit variable) interaction term, and the trajectories of treatment 
responses over time based on time slope computed for each subject (continuous time variable).  
 
Secondary efficacy measures will be the PANSS positive symptom and negative symptom subscales, PANSS 
general psychopathology subscale, CGI-S, CGI-I HAM-A, CCDS, GAF, cognitive scales as with the primary 
endpoint using the same MMRM LDA analyses.  No multiplicity adjustment will be made in the secondary 
analyses. Appropriate descriptive statistics with 95% confidence intervals will be provided within and across 
treatment groups. Normal assumption will be checked and nonparametric alternatives will be considered if the 
assumption is seriously violated. 
 
Mediators and baseline moderators of treatment effects on efficacy outcome measures will also be explored 
(Kraemer et al., 2006).  The significance of moderator effects due to baseline characteristics (age, gender, initial 

 
 
Biomedical IRB Application Instructions 
Page 17 
PANSS scores, duration of illness, class of medication) will be tested using treatment-by-baseline characteristic 
interaction terms in the MMRM LDA and/or ANCOVA models. To assess impact of improvement in one domain 
(e.g. positive symptoms) on the efficacy of a related symptom domain (e.g. negative symptoms), a mediator 
analysis model with terms for treatment, baseline, and positive symptoms improvement will be applied to 
determine significance of oxytocin effect on reductions in negative symptoms after adjustment for potential 
positive symptom improvement. We will perform similar mediator analysis for assessing inter-relationships 
between cognitive improvement and symptom improvement in positive and/or negative symptoms. In addition, 
cross-sectional baseline and longitudinal change score associations between treatment outcome measures and 
mediator effects will be assessed by including mediators as time-varying covariates in the MMRM LDA models 
(Diggle et al., 2001). 
 
MU-Suppression. Data will be analyzed in two ways. Pearson rank correlations will be used to examine 
correlations between mu wave suppression in response to a single dose of OT and symptom severity at the end 
of 6 weeks of treatment. In additional exploratory analyses, mu suppression values will be split at the median into 
High suppressors and Low suppressors and followed up by correlations with symptom measures to determine if 
initial high suppression is correlated with greater improvement in symptom severity. Secondarily, Pearson rank 
correlations will be conducted between mu wave suppression and symptom severity at baseline, and between 
mu wave suppression and symptom severity after administration of a single dose of oxytocin. 
 
Safety Endpoints. The safety dataset will contain all subjects who take at least one dose of oxytocin.  All adverse 
events will be coded using the most current version of the Medical Dictionary for Regulatory Activities 
(MedDRA).   The number and percentage of subjects reporting treatment-emergent adverse events will be 
tabulated within each dose group by treatment, system organ class (SOC) and MedDRA-preferred term.  
Treatment-emergent adverse events will be those adverse events that begin or worsened following the first dose 
of study drug.  .Adverse events will be further classified by severity and investigator-assigned relationship to 
study drug. 
 
Clinical laboratory values and vital signs measured at the end of each treatment period will be analyzed using 
ANOVA, with factors sequence, period and treatment. Dose-response relationships will be explored and any 
laboratory values that fall outside normal ranges will be identified. 
 
Missing Data. Some observations may be missing after baseline assessment. Individual missing items in all 
scales will not be imputed. All subjects expressing the desire to discontinue the study will be asked to come in for 
a final assessment, prior to stopping their medications. The primary analysis will be based on the likelihood 
based mixed-effects model (MMRM LDA) which provides valid estimates of treatment effect under the missing at 
random (MAR) assumption. The assumptions about random dropout and MAR can be tested using methods 
proposed by Diggle et al. (2001) and dropout cohort visualization as in Potkin et al, (2009). Two sensitivity 
analyses will be conducted to evaluate the robustness of results: one based on a mixed-effects model for 
missing not at random (MNAR) data with covariate adjustment for dropout measures (Wu and Follmann, 1999; 
Wu et al., 2001), and the other based on the usual LOCF-ANCOVA method with missing data following dropout 
imputed by an individual’s last observed measurement. Further details are provided in the Statistical Analysis 
Plan, which will clearly specify the mixed-effects model methodology, sensitivity analyses, and evaluation of the 
assumptions.

changes to sleep aids. 
 
 
 
 
Discontinuation Criteria 
The criteria for enrollment must be followed explicitly.  If a subject who does not meet enrollment criteria is 
inadvertently enrolled, that subject should be discontinued from the study.  In addition, subjects will be 
discontinued from the study and/or from the study in the following circumstances: 
 
1.   If Exclusion Criteria, as listed above, are observed or develop after entry or enrollment, the subject will be     
discontinued from the drug/study at the next visit or sooner in the event of a safety exclusion criterion. 
2.    The subject or attending physician requests that the subject be withdrawn from the study. 
 
 
No subjects will be excluded from participation based on race, ethnicity or gender.   
 
 

 
 
Biomedical IRB Application Instructions 
Page 19 
If patients need to be discontinued due to lack of efficacy or intolerance from study medication a study 
psychiatrist will meet with them an assess their clinical status. Additionally, addressing the patient’s ongoing 
treatment needs (once out of the study) is proactively addressed with the patient on study entry, as in many 
cases anxiety disorders are chronic conditions in need of ongoing care.  Study psychiatrist will discuss non-
investigational options for controlling subjects anxiety taking into account treatments subjects has been on in 
the past, if any. In collaboration with subject, study physician will initiate any treatment of anxiety as deemed 
appropriate. A referral plan will be developed with subject for him/her to continue treatment with an outpatient 
psychiatrist. Subject will be followed and cared for by study physician without cost to subject until subject has 
been able to transfer care to another provider or until patient is deemed stable and has chosen not to pursue 
care by another provider. After study care of subject will be documented in a medical record. 
 
 
Sources of Materials 
 
-Data that will be collected from human subjects for this project includes ratings scales interviews and 
responses to patient self-rated scales.  In addition, blood and urine samples will be collected to perform routine 
laboratory tests and drug screens.   
-Access to individually identifiable private information about human subjects will be limited to research staff 
affiliated with the project.  Research records will be kept confidential to the extent provided by law.  The 
collection and submission of medical information will be accomplished with strict adherence to professional 
standards of confidentiality.  Patients’ medical information will be held in a secure location.  
 
-Data regarding schizophrenia symptom severity will be collected via interviews with a staff clinician and via 
patient self-rated scales.  Study coordinators will also conduct an interview to establish a medical and 
psychiatric history for each patient.  Blood and urine samples will be collected via the UCSD Medical Center 
Outpatient Phlebotomy Center.  All data will be collected specifically for the proposed research project. 
 
11. 
RECRUITMENT 
 
Potential subjects will be recruited through several sources.  Ads/flyer will be posted in adult clinics, day 
treatment programs in the county and distributed to colleagues.  Approval may be sought from San Diego 
County Mental Health for recruitment from county run facilities.  Recruitment Flyer is included with this 
application. 
 
12. 
INFORMED CONSENT 
 
Prior to entry in the trial, the investigator(s) will explain to the potential subjects the aims, methods, reasonably 
anticipated benefits, and potential hazards of the trial and any discomfort it may entail.  Subjects will be 
informed that they are free to not participate in the trial and that they may withdraw consent to participate at 
any time. They will be told what alternative treatments are available if they refuse to take part and that such 
refusal will not prejudice future treatment.  Finally, they will be told that competent physicians/lab personnel 
may examine their records but that personal information will be treated as strictly confidential and will not be 
publicly available. Subjects will be given the opportunity to ask questions about the study. After this 
explanation and before entry to the trial, the subject’s consent will be obtained. If signed informed consent 
cannot be obtained, the subjects will not be included in the trial. Subjects who are conservatorized will be able 
to participate in this study if their conservator signs consent. 
 
13. 
ALTERNATIVES TO STUDY PARTICIPATION 
 
In order to receive treatment for this disorder it is not necessary to participate in this clinical trial.  There is a 
large variety of FDA approved antipsychotic medications available by prescription from the patient’s 
physician/psychiatrist. 

 
 
Biomedical IRB Application Instructions 
Page 20 
 
Alternative treatments for schizophrenia include the use of conventional antipsychotic medications, such as, 
but not limited to, risperidone, olanzapine, quetiapine, or haloperidol.  Each of these medications carries their 
own risk of side effects which can include transient or permanent tardive dyskinesia.  Potential benefit of these 
alternate treatments may include the availability of greater scientific information regarding the medications 
because these medications are FDA-approved and readily available. 
 
14. 
POTENTIAL RISKS 
 
All medications have side effects and some of these can be unexpected and unforeseen.  Subjects will be 
closely monitored throughout the trial duration and subjects will be provided emergency contact numbers to 
ensure 24-hour monitoring. 
 
Nasal Inhalation Oxytocin 
The FDA (see appended letter)  notes “ lack of safety concerns” associated with the clinical use of oxytocin 
despite “, the length of marketing history of this product in the U.S., the continued availability of the injectable 
oxytocin in the US and the IN form outside the US” A drug insert provided with IN nasal oxytocin in Europe 
where it continues to be marketed for lactation lists the following  risks; painful uterine contracts; in rare 
occasions, allergic skin reactions, nausea or headache. Several  published studies have used  various doses 
(18- 360 IU) of IN oxytocin administered once to more than a week (e.g. Ansseau et al, 1987; Epperson 1996 ; 
Fehm-Wolfsdorf et al , 1988; Westenberg ,1992; Kosfeld et al 2005;  Ruis et al, 1981; Heinrichs et al 2003; 
Fewtrell et al 2005;  Bruins et al 1992.) Most studies do not report any adverse effects. One case (Ansseau et 
al, 87) of a patient developing reversible memory loss, psychosis, and a decrease in plasma sodium and 
osmolality is reported which is consistent with a picture of SIADH. Some studies reported decreases in verbal 
recall and memory whereas others did not find this. Other rare mild and transient effects were reported in 
some studies including, dry mouth, mild dizziness, mild headache, and mild nasal irritation. No effect on blood 
pressure has been noted. 
 
Risks of  Blood Draw 
During the study, blood will be drawn 8 times for chemistry basic panel.  Some problems from this are: pain, 
bleeding, bruising, swelling, dizziness, fainting, in rare cases, infection at the insertion site.  
Additional Risks 
Since this is an experimental treatment there may be some unknown risks that are currently unforeseeable.  
Subjects will be informed of any significant new findings. 
Symptoms of schizophrenia may not improve or may worsen.  There is also the possibility that there may be 
unforeseen risks associated with this test article, which are not yet known.   
 
 
Allergy Risks 
As with any drug, there is a chance that the subjects may have an allergic reaction to the drug.  Symptoms of 
an allergic reaction may be a skin rash, hives or more serious problems like trouble breathing and shock.  It is 
not possible to predict in advance who will develop these problems. 
 
Female subjects will be instructed to use one of the following acceptable methods of birth control throughout 
the study:   
 
oral or patch contraception  
 
Depo-Provera® or other intramuscular injection  
 
implantation of levonorgestrel (Norplant®) system or an IUD  
 
barrier methods (combination of diaphragm and spermicide or condom and spermicide)  
 
Risk of Disclosure 
Subjects will be asked to provide a urine sample to be tested for certain types of controlled substances that 
may be regulated by law.  Additionally, information about subjects’ mental and physical health collected 

 
 
Biomedical IRB Application Instructions 
Page 21 
throughout the study will also be kept with research records.  Disclosure of this kind of information is a risk of 
being in the study. Disclosure of this kind can affect a subjects’ ability to get a job, obtain life or health 
insurance, employment or ability to adopt children.  Confidentiality risk will be managed by keeping subjects’ 
information completely confidential, stored in a secured location and disclosed only as required by law.   
 
Other Risks 
Participation includes a urine toxicology and pregnancy test.  It is possible that a positive drug screen may 
becomeknown outside of the research setting and it could potentially jeopardize the subjects’ ability to acquire 
a job or insurance. 
 
EEG mu suppression paradigm exposes subjects to the application of electrodes. The possibility of skin 
irritation from application of paste exists, however, is unlikely given that the salt concentration of the paste is 
similar to that of human sweat. 
 
As with any drug, participants are faced with the possibility of side effects.  Other studies of oxytocin report side 
effects such as dry mouth, mild dizziness, mild headache, and mild nasal irritation.  Because the treatment 
proposed in the study is investigational, there is a risk that participants’ symptoms of schizophrenia may stay the 
same or worsen.  There may also be other risks or side effects which are currently unknown.  Possible side 
effects from venipuncture include faintness, inflammation of the vein, pain, bruising, or bleeding at the site of 
puncture.  There is also a slight possibility of infection as a result of the blood draw procedure.  Women of child-
bearing potential are asked to utilize an approved method of birth control during study participation as risks to a 
fetus are unknown.  Urine and blood samples collected during this study will be utilized to screen for illicit 
chemical substances.  The results of these tests will be kept confidential and may be disclosed as required by 
law. It is possible that positive drug screen results may become known outside of the research setting; if this 
information were disclosed, it could potentially jeopardize a subject’s ability to obtain employment or insurance. 
Additionally, some of the information to be collected for this study includes information on patient diagnosis.  
There is a risk that this information can become known outside of the research setting.  This information, if 
disclosed, could also potentially jeopardize a patient’s ability to obtain employment or insurance.  The study staff 
will manage this risk by storing all study information in a secure location in a locked facility. No information about 
subject participation will be provided to anyone outside of the necessary research staff without subject’s written 
permission.  
 
Potential subjects will be recruited through several sources in the community surrounding the UCSD Medical 
Center.  Flyers will be posted in adult clinics, day treatment programs, and distributed to colleagues.  
Advertisements will be placed in local community publications and online forums, and a local press release will 
be made. 
 
Prior to entry in the trial, the investigator(s) or study coordinator(s) will explain to the potential subjects the 
aims, methods, reasonably anticipated benefits, and potential hazards of the trial and any discomfort it may 
entail.  Subjects will be informed that they are free to not participate in the trial and that they may withdraw 
consent to participate at any time. They will be told what alternative treatments are available if they refuse to 
take part and that such refusal will not prejudice future treatment.  Finally, they will be told that competent 
physicians/lab personnel may examine their records but that personal information will be treated as strictly 
confidential and will not be publicly available. Subjects will be given the opportunity to ask questions about the 
study. After this explanation and before entry to the trial, the subject’s consent will be obtained and 
documented via signature of an informed consent form by both the patient and the person conducting the 
informed consent discussion. If signed informed consent cannot be obtained, the subjects will not be included 
in the trial. Subjects who are conservatorized will be able to participate in this study if their conservator signs a 
consent form on their behalf. 
 
15. RISK MANAGEMENT PROCEDURES AND ADEQUACY OF RESOURCES 

 
 
Biomedical IRB Application Instructions 
Page 22 
 
A staff that is highly qualified in the assessment and treatment of schizophrenia in adults will closely monitor 
subjects in this study.  This monitoring includes the frequent periodic assessments involved in the study 
protocol, which occur at intervals of 1 week long. Study drug will be administered on site following both 
baseline visits.  Mid-week calls are set up following both baseline visits along with a study treatment follow up 
visit.  In addition, subjects will be monitored throughout the study for any adverse events. Subjects will be 
instructed by the Investigator to report the occurrence of any adverse events immediately.  At the beginning of 
each treatment period, the Investigator will query the subjects, in a generalized fashion, whether any clinical 
adverse events have occurred since the last visit.  Any serious or unexpected event, including death due to 
any cause, whether or not related to the study drug or procedures, will be reported to the UCSD HRPP within 
10 days.   
 
After a thorough literature search was performed and confirmed the relative safety profile of this drug, the 
following additional safety measures were added in an attempt to be thorough. 
 
Biological safety measures include blood chemistry and urine osmolality to monitor for SIADH. These tests will 
be done at screening and at every visit after randomization. In addition a blood metabolic assay (glucose, liver 
enzymes) will be conducted at each visit.  
 
If any clinical worsening or serious adverse event is detected during the course of the trial that cannot be 
managed by a dose adjustment, the subjects will be discontinued from the protocol.  
 
It is my intention to provide contact information for study staff to the subjects and reiterate this information at the 
time of each visit.  Contact information for PI, and Drs. MacDonald and Becker, are listed on the diary form that 
will be provided to the subject at each visit.  Study subjects will be encouraged, as documented in the consent 
and on the separate diary form, to contact the study team with medical concerns, reactions, and experiences. 
Subjects will be given a diary form to complete upon each use for administrations that are done between site 
visits.  This diary form includes 24 hour emergency contact information (including PI, sub-Is and study staff), 
nearest emergency department from subject’s residence and concomitant medication diary.    
 
At the termination of the project or in the event that any subjects will need to be discontinued from the study due 
to lack of efficacy or an adverse event, one of the study doctors will arrange for subjects to receive appropriate 
treatment for any symptoms that require stabilization. The study staff will also help arrange routine follow-up for 
subjects’ symptoms of schizophrenia (e.g., referral if required) and will provide standard medication treatment of 
schizophrenia to subjects until such follow up is available.  
 
Subjects will have 24-hour access to emergency psychiatric care and will be provided with a means of 
contacting the on-call study doctors and research staff at the UCSD Medical Center.  Subjects will be informed 
and encouraged to contact study physicians and staff immediately with medical concerns or unusual reactions. 
This information will also be listed on the diary cards provided to subjects at every visit along with the 
identification of the closest Emergency Department location to their residence.  PI and sub-investigator phone 
numbers for 24-hour access has been listed in the consent form.     
 
Confidentiality risk will be managed by keeping all of each subjects’ data completely confidential, and stored in a 
secured filing cabinet and on Clinical Conductor, a secure, password protected clinical trials administration 
database.  The data collected for this investigation will be used for research and treatment purposes only.  Data 
will be available only to those directly involved with the study, HRPP, and the FDA. 
 
Research records will be kept confidential to the extent allowed by law.  The following people will have access 
to the study data collected for this study:  Dr. Feifel and study staff listed below, UCSD HRPP, the grant 
funding agency, National Institute of Mental Health, representatives of the grant funding agency and 
government agencies where permitted or required by law (such as the Food and Drug Administration (FDA) 
and the United States Department of Health and Human Services).  

 
 
Biomedical IRB Application Instructions 
Page 23 
 
Research records will be kept confidential to the extent provided by law.  The National Institute of Mental 
Health, including its agents and contractors, the United States Food and Drug Administration or other 
regulatory authorities, and similar ethics committees and regulatory agencies in other countries, as well as the 
UCSD Institutional Review Board,mayreview original medical and research records in connection with this 
study.  Medical records that contain subject identity will be treated as confidential and will be shared only with 
these agencies, or as required by law.  Medical information may be held and processed on a computer. The 
results of this research may be published in scientific journals or presented at medical meetings, however 
subject name will not appear in any publications or reports produced from this study. 
 
16. PRIVACY AND CONFIDENTIALITY CONSIDERATIONS INCLUDING DATA ACCESS AND MANAGEMENT 
 
In order to maximize patient privacy, all consenting will be done in a private room in an office, where the 
participant can ask questions without feeling uncomfortable or embarrassed.  If and when the study doctor needs 
to perform a physical exam, the patient will be provided with a private room to undress and dress. While 
receiving the physical exam the only person who will be in the room other than the patient will be the study 
doctor conducting the exam.  If, however, the study doctor is of the opposite gender to the patient, a staff 
member of the same gender as the patient will also be in the room during the physical exam. 
 
Confidentiality will be maintained through physical and electronic security measures.  The study office where 
patient files are maintained is kept locked, and only authorized research staff are allowed access.  Research 
participant information stored electronically is maintained on computers with appropriate UCSD approved 
security firewalls, password protection, and other data storage safety measures.  
 
Once a subject has enrolled in the study, a sequential Subject Identification (SubID) Number will be assigned. 
The SubID number is to be recorded on all study documents and will link the study treatment and the study 
documents to the subject’s name and medical record. To maintain confidentiality, the subject’s name will not be 
recorded on any study document other than the informed consent. 
 
Patient’s blood or urine sample will be tested for certain types of drugs (known as controlled substances in the 
United States) that may affect behavior and that may be regulated by law.  If test results show that they have 
taken these types of drugs, they will be notified.  The results of this test will be kept confidential and disclosed 
only as required by law.  It is possible that positive drug screen results may become known outside of the 
research setting.  If this information was disclosed, it could potentially jeopardize their ability to get a job or 
insurance. 
 
17. POTENTIAL BENEFITS 
 
No direct benefit can be guaranteed to the individual subjects. The subjects may benefit from the formal 
diagnostic procedures, required assessments, and increased scrutiny during the study, which are more 
rigorous than the community standard for diagnosis and assessment.  A more general benefit of this study will 
be a greater understanding of the benefits of intranasal oxytocin augmentation. 
 
18. RISK/BENEFIT RATIO 
 
The potential benefits of this investigation outweigh the risks involved. Subjects will continue on their current 
regimen of antipsychotic therapy. If intranasal oxytocin is found to decrease associated symptoms, it could 
potentially benefit many people. All subjects will be receiving close medical supervision and an active 
antipsychotic. The health and safety of individual subjects will be the top priority of all study investigators. 
 
Current treatments available for schizophrenia are unsatisfactory, and many patients continue to suffer from 
their symptoms even with treatment.  Information obtained as a result of this trial may assist in the 

 
 
Biomedical IRB Application Instructions 
Page 24 
development of superior treatments for schizophrenia and related illnesses. 
 
19. EXPENSE TO PARTICIPANT 
 
There is no expense to the subjects for any of the research activities.  
 
20. COMPENSATION FOR PARTICIPATION 
 
Subjects will receive $80 per visit (paid at each visit) to compensate them for time, travel and inconvenience. 
 
If a separate visit is required to complete the Mu-suppression paradigm subjects will be compensated an 
additional $50 per extra visit. 
 
21. PRIVILEGES/CERTIFICATIONS/LICENSES AND RESEARCH TEAM RESPONSIBILITIES

30. PROCEDURES FOR SURROGATE CONSENT AND/OR DECISIONAL CAPACITY ASSESSMENT 
 
Subjects who have impaired intellectual capacity to comprehend the informed consent as demonstrated using 
the “Capacity to Consent Form” (included with this submission)will not be enrolled in this study.  Patients who 
are conservatorized will only be included if they consent to be in the study and their designated conservator 
consents. In many instances, conservatorized patients have the cognitive capacity but not the legal capacity to 
consent to treatment. If a conservatorized patient demonstrates cognitive capacity to provide consent based 
upon the “capacity to consent form” AND consents to participating in this study, then the potential subject’s 
conservator will be contacted, informed of the subject’s consent. Informed consent for the subject’s 
participation will then be sought from the legal conservator as described in item 11 above (without “capacity to 
consent form”) and he/she will be asked to sign the “Legal Conservator” signature line below the subjects 
signature. Thus, conservatorized subjects will only be enrolled if they demonstrate (cognitive) capacity to 
consent, consent to participate, and their legal conservator provides informed consent.
