Brief summary:
While there are many effective options for treating a major depressive episode, there are no clinical markers that predict the likelihood of remission with an initial trial of either an antidepressant medication or psychotherapy. The goal of this study is to test how brain function changes in depress patients treated with cognitive behavioral therapy (CBT) compared to patients treated with a selective serotonin reuptake inhibitor (SSRI, either escitalopram or sertraline), which are FDA approved antidepressants. The study aims to determine if bran scan findings might help physicians to select the most effective antidepressant treatment for an individual patient.

Up to 100 male and female outpatients who are between 21-55 years old will be enrolled. Participation in the study will last from 14-26 weeks.

Subjects will be randomized to receive either escitalopram (s-CIT) or CBT for 12 weeks. Resting-state positron emission tomography (PET) and BOLD functional magnetic resonance imaging (fMRI) scans will be done before the treatment begins, and again at the end of treatment (week 12). Non-responders to s-cIT or CBT will be crossed over to receive an additional 12 weeks of treatment with the alternative intervention.

Detailed description:

Arms: arm 1: Escitalopram, pill form, 20mg-40mg, daily, for 12 weeks or Sertraline, pill form, 50 - 150 mg, daily for 12 weeks arm 2: Cognitive Behavioral Therapy (CBT) CBT will include 16 1-hour sessions provided over 12 weeks.
Interventions: intervention 1: Selective serotonin re-uptake inhibitor intervention 2: Cognitive Behavioral Therapy intervention 3: Combination treatment (SSRI + CBT)
Intervention descriptions: intervention 1: Escitalopram, 20mg-40mg daily or Sertraline 50-150 mg daily for 12 weeks intervention 2: Cognitive Behavioral Therapy, standardized, 16 sessions over 12 weeks. intervention 3: study participants who do not remit in the first 12 weeks will be offered combination treatment of both treatments for 12 more weeks.

Precise/Abstract: 
 
 
Introduction and Background:  
 
Imaging-based diagnostic tests are routinely used in the clinical management of many medical 
illnesses.  In ischemic heart disease, for example, evaluation of the integrity and caliber of the 
coronary arteries combined with tests of myocardial function are critical determinants of the 
interventional strategy initiated following the diagnosis of an acute myocardial infarction [1].  The 
decision by a cardiologist to treat medically or surgically is neither arbitrary nor conciliatory. 
Rather, they are based on objective measurements of the primary organ of interest considered 
in context of other contributing risk factors, including genetics, co-morbid medical conditions 
(i.e., hypertension, diabetes, hyperlipidemia) life-style factors (smoking, diet, exercise) and past 
cardiac problems.  Currently, the choice of treatment for major depression (MDD) is based on 1) 
trial-and-error, 2) the skills and preferences of the clinician treating the patient (i.e. psychiatrist 
or therapist) who chooses a treatment based on their training and ideology, or 3) patient 
treatment preferences [2].   
 
For a patient presenting with a major depressive episode as part of major depressive disorder 
(MDD), an antidepressant medication or evidence-based psychotherapy is the recommended 
first-line treatment. However, fewer than 40% of patients achieve remission with any initial 
intervention (monotherapy), and choosing the “wrong” treatment has significant individual and 
societal costs due to continued distress, risk of suicide, loss of productivity, wasted resources, 
and potential unintended neural effects associated with two to three months of an ineffective 
strategy [2]. To minimize these costs and improve the clinical care of patients with MDD, a 
crucial goal is to develop a dependable treatment selection algorithm that matches an individual 
patient to the treatment option most likely to be successful. To have meaningful clinical impact, 
such an algorithm must lead to remission rates that exceed the usual 35-40% commonly 
reported with usual care. Critically, such an algorithm should select the best treatment while 
also avoiding the worst treatment, and also identify patients that require other alternatives. 
 
In developing a reliable biomarker to guide initial treatment stratification to standard first-line 
treatments such as CBT or sCIT, it is also necessary to differentiate those patients that require 
non-standard treatment options. A 35-40% non-remission rate is typical of trials where a 
randomized treatment is followed by a second medication or combination medication and 
psychotherapy. Given that further increases in medical and psychosocial costs are associated 
with two failed standard first-line treatments, it is essential to know in advance if a patient is a 
poor candidate for these usual options.  
 
We previously conducted a trial of 82 patients with MDD who were randomly assigned to 12 
weeks of treatment with either cognitive behavioral therapy (CBT) or the antidepressant 
escitalopram (ESC).  Using a pre-treatment fluorodeoxyglucose positron emission tomography 
(FDG-PET) measure of metabolic activity, we found that the ratio of metabolic activity in the 
insula relative to whole brain metabolism predicted remission and non-response to the two 
treatments.  Specifically, patients whose insula activity was below the whole brain mean were 
highly likely to remit with CBT and have a poor response to ESC.  Conversely, those with 
relatively high insula activity required ESC to remit, and responded poorly to CBT [3]. This 
earlier trial also contained an additional 12-week combination treatment phase for patients who 
did not remit to their original 12 weeks of treatment with ESC or CBT.  In this phase, we found 
that for patients were more likely to achieve remission if their added second treatment (whether 


Version #4 10-24-2014 
Page 3 of 19 
 
 
ESC added to CBT non-remitters, or CBT added to ESC non-remitters) matched the baseline 
insula activity signal predictive of remission [4].  This trial provided the first evidence that a 
biomarker could predict differential outcomes to two contrasting treatment approaches for MDD. 
The current study aims to replicate the findings of the earlier trial, with the long-term goal of 
achieving a personalized medicine approach to MDD, in which individual patients receive 
treatments most likely to help them specifically, based on their brain activity. 
 
Objectives 
Aim 1a.  To prospectively test the efficacy of the anterior insula TSB to assign individual MDD 
patients to 12 weeks of treatment with either CBT or sCIT.   
Hypothesis 1a. Assigning treatment based on the anterior insula TSB will result in 
remission rates of 50% or greater, exceeding current benchmarks.   
Exploratory Aim 1b.  To characterize metabolic change patterns associated with successful 
and unsuccessful treatment in the insula-defined depression subgroups. 
Hypothesis 1b. Insula activity will change as a function of remission status within each 
treatment. Differential treatment and remission specific changes in depression-relevant regions 
will also be seen. 
 
Aim 2.  To further characterize baseline biomarkers predictive of treatment non-response after 
completing 24 weeks of two first-line treatments for MDD.   
Hypothesis 2. Non-response to both 12 weeks of insula TSB-assigned monotherapy and 
12 weeks of combined CBT and sCIT will show a baseline metabolic pattern distinct 
from remitters to TSB-defined monotherapy and from remitters to combined treatment, 
defining a treatment resistant subtype.

The schedule of events is listed in Table 1.   
 
PHASE 1 
 
Screening Visit 
 
The screening visit will require approximately 3 hours. Patients will start by signing the 
informed consent form after all their questions about the study have been answered to their 
satisfaction. A study rater will administer the HAMD to assess depression severity. Patients with 
a HAMD ≥18 will go on to complete the SCID-IV to confirm MDD diagnosis and ensure any 
exclusionary psychiatric diagnosis is not present.  A medical history, physical exam, 
electrocardiogram (EKG), blood tests (15cc for complete blood count, comprehensive metabolic 
panel, thyroid function screen, pregnancy test) and a urinalysis and urine drug screen, will be 
performed to ensure the patient is medically appropriate for the study. An additional 10cc 
plasma tube will be collected for genetics analysis. Additional questionnaires regarding personal 
and family history of depression, smoking history, beliefs about depression, and concomitant 
medications will be administered.  Patients who meet all inclusion and no exclusion criteria at 
the end of this visit will be scheduled for the Scanning Visit within 10 days. 
 
Questionnaires completed by the patient at this visit include the following: 
 
Edinburgh Handedness Scale 
 
Hollingshead Scale of Socioeconomic Status

This visit will require approximately 3 hours and will occur at the Wesley Woods Center.  
Patients unwilling or unable to do the FDG-PET scan and the MRI scan on the same day will 
have the scans scheduled over a 2-day period.  The FDG-PET scan will be performed prior to 
the MRI scan whenever possible.  The Positive and Negative Affective State scale (PANAS) will 
be rated at the beginning and end of each scan to monitor fluctuations over the scanning 
session.  Analogue Mood Scales (10-point Likert) will be used to rate euthymia, anxiety and 
sadness and the start and finish of each scan.   
 
Baseline Visit 
This visit will require approximately 90 minutes.  Vital signs will be measured and inquiry about 
any concomitant medication changes will be made. 
Patients will be assessed by a trained interviewer with the following instruments: 
 
HAMD 
 
Montgomery-Asberg Depression Rating Scale (MADRS)  
 
Hamilton Rating Scale for Anxiety (HAM-A) 
 
Clinical Global Impression-Severity (CGI-S) scales 
 
Patients will complete the following questionnaires:  
 
Beck Depression Inventory-II (BDI-II)

Blood will be collected for the following measures: 
 
 
Methylation (6cc) 
 
Immune measures and metabolomics (10 cc) 
 
RNA (6 cc) 
 
Additionally, study patients will complete an extended vital sign assessment, consisting of 3 
heart measure tasks (two subjective, one objective): 
 
Heart Rate Measure  
 
7 Minute Heart Rate Recording Task  
 
Affective Bias Task 
 
 
Upon completion of all questionnaires and interviews, the patient will meet with a study 
physician to be informed of their treatment assignment. The study physician will answer any 
questions about the treatment or future study visits.  
 
Phase 1 Post-baseline Visits 
 
Patients will return weekly for the first four weeks (Visits 3-6) and the every other week for 
weeks 5-12 (Visits 7-10). These visits will last approximately one hour. Vital signs and changes 
in concomitant medications will be assessed. At each visit, patients will be assessed by an 
interviewer with the HAMD, MADRS and HAMA. Patients will complete the BDI-II, QIDS-SR, 
FIBSER and  self-report forms. They will meet with a study physician, who will administer the 
CGI-S and CGI-Improvement (CGI-I) scales. Adverse events will be discussed with the study 
physician, and dosing adjustments, if permitted (see below), will be made.  
 
At the week 6 (Visit 7) visit, patients will also complete the SDS, Q-LES-Q, DEBS and PSQI. 
They will also complete the PROMIS Anxiety and the PROMIS Depression Scale. 
 
At the week 12 visit (visit 10), patients will undergo repeat FDG-PET scanning at the CSI and 
then come to the come to the MAP offices to complete the visit assessments.  In addition to all 
the measures collected at week 6, patients will also complete the Body Awareness 
Questionnaire, PABS, RFDQ, MLCI, LOT-R, RRS, and ERQ.  Blood will also be collected to 
repeat the methylation, immune, metabolomics and RNA measures, as well as to measure 
pharmacokinetic values of escitalopram (10 cc, for total blood volume draw of 32cc). Total time 
for completion of all components at Visit 10 is approximately four hours. If patients have 


Version #4 10-24-2014 
Page 7 of 19 
 
 
insufficient time to complete both the PET scan and the clinic visit on the same day, the PET 
scan will be scheduled as close as possible to the clinic visit, with a maximum of 7 days 
between the PET scan and clinic visit. 
 
Patients who are non-responders to treatment will cross-over to the alternate treatment and will 
have the week 12 blood draws and questionnaires repeated at week 24.  
 
PHASE 2 
 
Visit procedures in Phase 2 will depend on whether or not the patient remitted (defined below) in 
Phase 1.  
 
Remitters at the end of Phase 1 will return at monthly intervals to measure their vital signs and 
report concomitant medications, and will complete the HAMD, MADRS, HAMA, CGI-S, CGI-I, 
BDI-II and QIDS-SR.  Total time for this visit is about one hour. Patients on escitalopram will 
receive one month’s supply of medication at this visit, and patients receiving CBT will have a 
CBT booster session if they desire it.   
 
Non-Remitters at the end of Phase 1 will enter another 12 week treatment course that replicates 
the treatment course and visit frequency of Phase 1 (see Table 1). The only differences from 
Phase 1 are that in Phase 2 there are no PET scans, and the patients continue with their Phase 
1 treatment in addition to starting the Phase 2 treatment (see Study Treatments, below).   
 
Heart Rate Monitoring 
 
As a potential non-imaging surrogate for insula activity, we will ask patients to count their heart 
beats while their actual pulse rate is monitored. A soft tone will indicate the start and end point 
for each counting interval. Actual pulse will be monitored with electrodes on their left and right 
wrists and clavicle. The test will be administered at the baseline and week 12 scans, as well as   
a third time for patients completing the week 24 visit. Subjects will complete the Body 
Awareness Questionnaire each time they perform the heart rate monitoring task. 
 
Heartbeat perception will be measured using the Mental Tracking Method  [15]. Between onset 
and offset of a soft tone, the subject counts his/her heartbeat by concentration on bodily 
feelings.  The subject is not to take his/her own pulse to try any other physical manipulation, 
which might facilitate the detection of heartbeats. The task will be repeated 3 times, for intervals 
lasting 25, 35, and 45 seconds respectively.  After the termination of each perception interval, 
participants will report the counted/estimated number of heartbeats. The subject will not be 
informed about how many seconds the 3 trials lasted or about their performance. 
 
The following intervals will be used: 
Rest (60 sec); Perception (25 sec) 
Rest (30 sec); Perception (35 sec) 
Rest (30 sec) Perception (45 sec) 
Rest (60 sec) 
 
Stationary objective 7 Minute Heart Rate Recording  
The patient’s heart rate will be recorded for 7 minutes while they sit stationary and look at a 
printed cross on a sheet of paper.  Prior to beginning this recording, patients will be asked to be 
seated for 5 minutes.  


Version #4 10-24-2014

Affective Bias Task 
Participants will be asked to rate the level of emotion on faces presented on a computer screen. 
To rate the level of emotional intensity, participants will use the mouse to move a horizontal 
marker on a scale ranging from very sad to very happy. The emotion and intensity portrayed on 
each face will vary for each trail. During this task, participants’ heart rate will be recorded.

Brain Imaging Procedures 
 
1.  FDG PET scans   
 
 
Regional cerebral glucose metabolism will be measured using a 18F-fluoro-
deoxyglucose method (10 mCi FDG dose/scan; scan duration 60 seconds) [7-9]. Data will be 
acquired on a Siemens ECAT 921 PET scanner, operating in 3D mode Axial FOV 14.5 cm; 47 
reconstructed slices).  A total of 2 scans (Visit 1 and Visit 10) will be acquired, each lasting 
approximately 90 minutes. For each scan, a 5 mCi dose of 2-[18F]-fluoro-2-deoxy-D-glucose 
(FDG) will be injected intravenously, with image acquisition beginning after 40 minutes (scan 
duration 20 minutes).  Arterialized-venous blood sampling will be used to calculate absolute 
glucose metabolic rates. All subjects will be scanned during CSI business hours. under identical 
conditions: supine, awake, in the resting state with eyes closed and ears uncovered.  Patients 
will be advised to fast and avoid caffeine for four hours prior to the scan. Patients will be 
checked every ten minutes to ensure they are not asleep.  Patients will not be explicitly 
instructed to monitor internal mood state or to perform any specific cognitive task.  This 
approach aims to examine regional effects associated with the baseline depressed state without 
the potential interpretive confounds introduced by explicit manipulation of affective or cognitive 
state.   A debriefing session will follow the uptake period to document compliance with the 
instructions. PET scans will be performed prior to the fMRI scans. 
 
2.  fMRI Bold scans 
 
 
MRI acquisitions will be acquired using a Siemens 3T whole body scanner (Tim Trio) with a 60 
cm diameter bore. The MR imaging protocol includes an (1) anatomic image (7 min), (2) Two 
sets of different phase encoding DTI (16 min) and (3) two sets of resting state functional 
connectivity (15 min) acquisition [12] and a magnetic resonance spectroscopy scan (15 min).  
The anatomic imaging will be conducted for anatomic reference in fMRI and DTI data analysis, 
and volumetric analysis. The DTI images will be used to refine selection of regions-of-interest 
(ROI) for model-based analyses. Positive and negative affect will be assessed using the PANAS 
before and after the scanning session. These measures will be used for correlational analyses 
with brain data.   
 
To provide precise anatomical localization of identified functional differences between groups, a 
high-resolution anatomical image of the whole brain will be acquired. High-resolution anatomical 
imaging will be performed with a T1-weighted MPRAGE sequence optimized at 3T: 
TE/TR=5/35, matrix=256 x 208 x 196, FOV=256 x 208 x 192 mm2, 1mm isotropic resolution.  
Diffusion Tensor Imaging (DTI) will also be acquired to allow structural connectivity inferences 
between areas identified with the functional images. DTI images will be acquired using diffusion 
weighted single-shot spin echo-planar imaging (EPI) sequence in 66 axial slices covering the 
whole brain (TR/TE=3292/96 ms, matrix=128×128, FOV=256 mm×256 mm, slice thickness=2 
mm; 66 slices, and two opposite phase encoding directions). Diffusion weighting will be applied 
in 128 directions with a b-value of 1000 s/mm2. Resting BOLD imaging will collect T2*-weighted 
images: 10 oblique axial slices covering the subgenual cingulate, amygdala, hippocampus, 
hypothalamus and ventral striatum, and frontal cortical areas of interest (orbital frontal, medial 
prefrontal, dorsolateral prefrontal) to investigate areas of known abnormalities in previous PET 
studies.  
 
3. TSB Determination 


Version #4 10-24-2014

Following PET scan preprocessing, anterior insula activity values will be extracted using 
a standardized region of interest (237.35 mm3 spherical ROI centered on MNI coordinates x= 
+28.5, y= -21, z= -9) based on the original study findings. Patients with insula metabolism 
higher than their WBM (insula/WBM ratio >1) will be assigned to the escitalopram group; 
patients with insula metabolism lower than their WBM (insula/WBM ratio <1) will be assigned to 
the CBT group. 
 
Study Treatments 
 
1. Treatment Assignment for Phase I 
 
 
Once the PET scan data have been analyzed to determine the TSB, patients will return 
for their baseline visit to receive their treatment assignment.  Upon completion of the baseline 
visit study procedures, patients will meet with a study psychiatrist to be informed of their 
treatment assignment to escitalopram or CBT.  Importantly, to minimize placebo response 
emerging from expectation bias, and to maximize comparability with our original dataset, 
patients will NOT be informed that they are being treated according to their PET scan result. 
Instead, patients will be informed that while we are studying the utility of imaging to improve 
patient care, they are being randomized to treatment. This will replicate exactly what was done 
in our original study to develop this biomarker. This safeguard is crucial to ensure that any 
increase in remission rates we observe in our trial are the result of matching patients to the 
TSB, and not due to non-specific effects. Assessors administering the clinical rating scales will 
be blind to treatment group and method of treatment assignment.   
 
2. CBT Treatment 
 
All clinical guidelines for MDD include Cognitive Behavior Therapy (CBT) as a recommended 
treatment. For patients treated with CBT, therapy visits will occur twice weekly for 4 weeks and 
then weekly for weeks 5-12, for a total of 16 therapy sessions. Using a standardized protocol [5] 
enhanced with behavioral strategies, patients will learn to develop an awareness of how 
attitudes, beliefs or ways of thinking and thoughts produce and maintain depressed or anxious 
moods.  CBT pursues alleviation of depression through a systematic effort to change depressed 
patients' automatic and maladaptive beliefs or ways of thinking. At the heart of this approach is 
the assumption that distorted beliefs about the self, the world, and the future maintain 
depressive affect. Initially, patients focus on becoming aware of these thinking styles, and they 
then learn how to respond to them in ways that are more adaptive. Patients will be asked to 
monitor their thoughts, attitudes and beliefs, especially those accessed in the midst of 
problematic emotional situations.  During the course of treatment, the therapist focuses on 
modifying these habitual patterns of thinking through explicit cognitive or behavioral 
interventions and correcting maladaptive patterns such as perfectionism and excessive need for 
approval from others.  
 
 
The typical course of treatment comprises 16-20 sessions (16 planned in this study) and 
the sequence of treatment involves three stages. In the early stage (sessions 1-4) the emphasis 
is on establishing a therapeutic relationship with the patient, educating the patient about the 
CBT model and emotional lability, setting goals, and identifying and evaluating automatic 
thoughts. The middle phase (sessions 5 to 12) involves a gradual shift towards the identification 
of dysfunctional beliefs and compensatory strategies the patient may be employing, helping the 
patient to identify core beliefs and practicing skills at responding to and modifying 
depressogenic views. Tasks in the late stages of CBT (sessions 13-16) revolve around 


Version #4 10-24-2014

preparing the patient for termination, predicting high-risk situations relevant to relapse and 
consolidation of learning thought self-therapy tasks.  All therapy sessions will be recorded on 
DVDs.  Dr. Craighead or the treating psychologists will be available by phone to address any 
clinical concerns between clinical visits. In addition, the Working Alliance Inventory, therapist 
and client versions, (WAI-T and WAI-C), which measure the quality of the therapeutic 
relationship between therapist and patient, will be completed by both the therapist and patient 
after 2, 8 and 16 sessions of therapy have been completed. 
 
 
3.   Escitalopram Treatment  
 
Patients assigned to escitalopram will receive 10 mg/day for the first 3 weeks of 
treatment. Patients who show less than a 50% improvement from their baseline HDRS-17 item 
score by week 3 will have their dose increased to 20 mg/d. Patients who demonstrated 50% 
improvement at week 3 will be maintained on the 10 mg/day dose. Any patient who has failed to 
achieve the remission threshold (HDRS-17 ≤ 7) by week 6 will have their dose increased to 20 
mg/day at the week 6 visit. Patients unable to tolerate 20 mg/d will be down-titrated to 10 
mg/day. The escitalopram dose will not be changed during the last four weeks of each the 
treatment phase (week 8 in phase I, or week 20 in Phase II). Patients unable to tolerate 10 mg/d 
will be discontinued from the trial. This approach to dosing will ensure all escitalopram-treated 
patients are either treated to remission or receive at least 6 weeks at the 20 mg/day (or 
maximally tolerated dose), which is identical to the dosing schedule we used in our initial study. 
Side effects will be monitored at every study visit. 
 
4. Phase II Treatment 
a. Remitters 
Remitters in Phase I (defined below) will return at weeks 16, 20 and 24 during Phase II for 
ongoing monitoring of symptoms. Patients remitting with escitalopram will continue to receive 
that medication; CBT-remitters will receive 3 therapy booster sessions at monthly intervals.  All 
remitters will complete the following procedures at each of these three visits: 
 
Vital signs 
 
HAMD, MADRS, HAMA, and CGI assessments 
 
QIDS-SR, BDI-II, FIBSER, and SDS questionnaires 
b. Non-Remitters 
Patients who do not meet the remission criteria at week 12 will enter Phase II, during which 
they will continue their Phase I treatment, and start a course with the alternative treatment. Thus 
patients in Phase II will receive a combination of escitalopram and CBT. For patients receiving 
escitalopram in Phase I, the dose cannot be increased in Phase II, but may be reduced if side 
effects are intolerable.  Patients receiving CBT in Phase I will have monthly CBT booster 
sessions at months 4, 5 and 6 with their therapist. As shown in Table 1, the schedule of events 
in Phase II replicates that of Phase I, with the exception that there is no repeat PET scan at the 
end of Phase II.   
 
At week 24, phlebotomy will be performed for pharmacokinetics, methylation, inflammation 
and RNA, and women of child-bearing potential will complete a urine pregnancy test. 
 
A study psychiatrist will be available by phone to address any clinical concerns between 
clinical visits for all patients.   
 
5. Early Terminating Patients 


Version #4 10-24-2014 
Page 13 of 19 
 
 
Patients who terminate their participation prior to week 12 in Phase I will complete the week 12 
assessments (with the exception of the PET scan).  Patients who terminate the trial early in 
Phase II will complete the week 24 assessments. All early terminating patients will receive 
assistance transferring their clinical care to another clinician. The date the patient is withdrawn 
from the study and the reason for the discontinuation will be recorded.  When a patient is lost to 
follow-up, extensive efforts will be made to contact the patient in order to determine why the 
patient failed to return. 
 
6. Patient Instructions 
 
 
Each patient will be advised of the importance of treatment adherence.  For patients on 
escitalopram, pill counts to confirm adherence will be conducted at each study visit. A missed 
dose may be taken within the same day. A missed dose the previous day should not be made-
up (i.e. doubled) the next day. If the patient has any questions about the study or other 
medications, the research physician may be contacted, if necessary through a 24 hour 
emergency number.  In the event that a study visit is missed, it will be rescheduled within 3 days 
whenever possible.    
 
7. Post-study follow-up 
 
 
To ensure that study participants are safely transitioned to alternative sources of care, 
the study physicians will offer additional brief visits as needed for up to one month following the 
patient’s completion of study participation. No additional research data will be collected at these 
visits. The visits will be conducted as standard of care visits until the patient’s care has been 
transferred to another clinician.   
 
8. Treatment Adherence and Rater Reliability   
 
As in our first study, we will ensure that the treatments delivered in this study adhere to their 
respective treatment protocols, using standard measures for pharmacotherapy and CBT, 
respectively. Medication adherence will be monitored using pill counts and pharmacokinetic 
sampling at weeks 12 and 24 for patients receiving escitalopram. CBT competence will be 
assessed by Leslie Sokol, PhD using the Cognitive Therapy Scale (CTS) [6] to rate a randomly 
selected sample (15%) of video recordings from each treatment, blocked on early, middle and 
late phases of intervention. Ongoing reliability data will be gathered for rating scales. New 
clinicians joining the treatment team will go through MAP’s standard apprenticeship for the 
ratings and special training for reliability prior to performing independent ratings. 
 
IV. Data Analyses 
 
A.   Treatment Response Assessments 
 
Definitions. 
Remission (RR) is categorically defined as a final score on the HAM-D scale for the week 10 
and 12 visits (which are separated by 2 weeks) of less than 8.  
Response (R) is defined as 50% reduction from baseline and a final score <15 at the week 10 
and 12 visits. 
Non-response (NR) is defined as a <30% improvement in HAM-D score from baseline to week 
12.  For non-remitters in phase II, NR is defined as failure to as a <30% improvement in HAM-D 
score from baseline to week 24.

Sample Size Calculation and Efficacy Thresholds 
 
Aim 1  
The efficacy of the biomarker to assign best treatment will be tested in this protocol 
using Simon’s ‘two-stage’ design [7] using exact binomial calculations. Simon’s two-stage 
design is commonly used for testing treatment stratification biomarkers; for example, for 
estimating remission rates of different established cancer treatments [8]. For the insula TSB 
being tested here, if the overall remission rate is below the threshold set for the first stage (see 
sample size in the next 2 paragraphs), then TSB-based assignment will be halted and treatment 
switched to assignment by randomization for the remaining patients.  
 
Sample size for this design is determined by first setting the threshold level at which we 
will consider the remission rate a failure. For our purposes, we set the threshold level to a 
remission rate of 35%, which is roughly equivalent to the remission rate expected from 
randomized or naturalistic treatment in depression [9 -11].The sample size is then calculated by 
setting the type I error=0.05, the minimum acceptable target level of remission (in this case, 
50% or a 15% increase in remission rate over threshold level) and the Type II error (beta=0.2 or 
power=0.80).  
 
With these parameters, the total sample size needed for the first stage of the Simon’s 2-
stage design is n=27 completers with 12 weeks of treatment. If 10 or more of those 27 subjects 
remit (i.e. 37%), the design will continue to stage 2 using the “treat by insula type” paradigm. 
The continuation will then require an additional 50 subjects for a total of 77 subjects. If a total of 
39 or more of the 77 subjects remit, then the stratification strategy will be considered worthy of 
further future testing. If less than 10 of the first 27 subjects remit, the trial will revert to 
randomized treatment allocation in order to complete data collection. This futility design ensures 
that we don’t continue to treat by the TSB if we cannot meet the 50% target remission rate in the 
full sample. At minimum, we require 77 subjects to complete all 12 weeks (i.e. have remission 
status) in order to test the efficacy of the biomarker to assign best treatment. If we allow for a 
20% dropout rate, which is consistent with our earlier trial, we will need to recruit a total of 96 
(approximately 100) subjects at baseline.  
 
Aim 2   
Given the expected 77 completers of the initial treatment phase and the projected 50% 
remission rate, we will have approximately 40 subjects enter the second 12-week (combined) 
treatment phase, and based on our original sample,16 will be non-responders (dual failures). 
Evidence from the original study points to several candidate dual-failure biomarkers significant 
at the 0.005 corrected level with a sample size as small as 11 (computed effect size range [1.2 
to 1.8]). We expect to have enough data from this study to define the dual failure biomarker as 
described.  
 
Heart rate accuracy analysis 
Formula for heartbeat perception score: Mean score across 3 heartbeat perception interactions 
as follows (direction of error is ignored) 
 
1/3∑(1- (|recorded heartbeats – counted heartbeats|)/recorded heartbeats) 
 
Scores vary from 0 to 1, with high scores indicating only small differences between recorded 
and counted heartbeats.

Source of Materials. 
 
Research information will be gathered using face to face interviews including past 
medical and psychiatric history, presenting complaints, current symptoms, standardized 
psychiatric and functional assessments. Patients will have a routine physical examination, and 
complete blood and urine assessments to assess their general medical condition.  Specific 
research blood tests of potential relevance to treatment response will also be obtained.  
Assessment and treatment sessions will be audiotaped and videotaped.  PET and fMRI scans 
will be obtained using standard research protocols within each respective laboratory. 
 
Protection again risks. 
 
 
Risks to participation include experiencing side effects from the study medications for 
the MDD subjects, exposure to radiation from the PET scan, and exposure to magnets in the 
MRI scanner.  Every effort will be made to protect against and minimize potential risks.  All 
information gathered will be coded by patient number rather than by name and research 
information will be kept under lock and key.  Information will not be divulged unless specifically 
requested by the patient in writing.  A certificate of confidentiality and sensitive study request will 
be pursued for this study.  
 
The main potential risk of a PET scan is exposure to low dose radiation.  Based on 
published dosimetry, the total effective dose equivalent for 2 FDG PET scans (10mCi/scan= 
20mCi/study) is 17.6 mSv.  This dose is less than the allowed dose for research subjects in a 
single year. Subjects will be educated regarding radiation exposure from PET scans.  
Placement of the IV needle required for injection of the radiotracer during the PET study can 
cause a small amount of bruising or pain.  Pregnancy is contraindicated for participation.  
Nonetheless, a pregnancy test will be done immediately prior to the PET session to ensure a 
non-pregnant status prior to radiation exposure. 
 
The risks associated with MRI are minimal.  Subjects will be screened for absolute 
contraindications to MRI, including presence of a pacemaker, aneurysm clips, neurostimulators, 
cochlear implants, metal in eyes, steel worker, metallic inter-uterine devices for birth control, or 
other implants.  Patients and volunteers will be briefed prior to the scan day to alleviate 
anticipatory anxiety regarding the procedure.  Claustrophobia is possible.  The study can be 
immediately terminated if this is not tolerated.  Study investigators and MRI technologists will be 
on site at all times during study acquisition to intervene under such circumstances.   
 
The treatment risks are consistent with the standard-of-care for MDD. Similarly to all 
antidepressant medications, escitalopram has common known side effects, including headache, 
nausea, anxiety, and sleep and appetite disturbances.  In patients under age 25, there is a small 
increased risk of developing thoughts of self-harm or suicidal ideas.    
   
Adverse event monitoring 
 
 
Adverse event information will be captured via two methods. At each visit, the study staff 
will ask the patient if they have experienced any changes in their mental or physical health.  Any 
reported adverse events will be assessed and, if needed, treated by a study physician.  In 
addition, patients will complete the FIBSER, which provide more quantitative measures of side 
adverse effect occurrence.  
 
Benefits to subject or future benefits 


Version #4 10-24-2014 
Page 16 of 19 
 
 
 
 
Patients who participate will receive an expert psychiatric assessment and treatment.  
With treatment, patients may experience an improvement in their symptoms of depression along 
with a potential improvement in their cognition.  Patients will have the benefit of participating in a 
clinical trial that could inform future treatment of patients with MDD 
 
Training 
 
 
No training is currently necessary for MAP staff for the rating scales used in this study 
because all research personnel involved in this project are currently trained on the scales used.  
New staff involved in patient assessment will be trained in scale administration according to the 
MAP’s usual training methods.  
 
Confidentiality 
 
 
Patients’ confidentiality will be maintained throughout the duration of their study 
participation. Patient names and other identifiers will not be included in assessment tools and 
datasets; a unique ID will be assigned. Patient files will be kept in locked offices, and the 
computerized data is kept on password-protected computers in the locked Mood and Anxiety 
Disorders Program offices. 
 
Informed consent 
 
 
At the screening visit, patients will be provided with an informed consent form that will 
outline the risks and benefits of participating in this study.  It will also outline which assessments 
occur at the various study visits.    
 
Deception 
 
 
Deception is a crucial and necessary component for this project.  A major confounder of trials 
studying treatments for depression is the placebo response. Although placebo response has 
many sources, a major driver is the expectation of improvement, which can be enhanced by the 
use of expensive procedures or new technologies that inspire greater confidence [12-14].  In 
this study we are using FDG-PET scans to assign patients to the specific treatment they will 
receive. We need to tell participants that their treatment is being randomly assigned to minimize 
the added expectation-effect on placebo response that would result from being told a new 
technology was guiding their treatment decision.  It is important to understand that we do not 
know if this approach really is superior to randomized treatment – this study is designed as a 
proof of principle study, with the outcome being that if we achieve greater than 50% remission 
rates, this will reflect preliminary prospective proof of the method.  If we were to achieve those 
high remission rates through exaggerated placebo responding, the point of the study would be 
undermined, and future resources inappropriately directed.  There are currently no methods to 
select best treatments for individual patients in clinical use.  Therefore, withholding the 
information about how treatment in this study is assigned does not represent a compromise of 
usual clinical care.  We have no evidence or reason to suspect that the PET scan-indicated 
treatment is likely to be worse than randomized treatment assignment. Thus, there are no 
anticipated harms to participants that would result from this deception; all participants will 
receive a standard-of-care treatment for depression, either evidence-based psychotherapy or 
medication. In order to prevent information about the trial design from disseminating into the 
general public, we will not debrief patients about the deception at the end of the trial. Because 


Version #4 10-24-2014 
Page 17 of 19 
 
 
this trial allows all participants to receive both treatments if the initially assigned treatment does 
not lead to remission in Phase 1, there is no harm in withholding this aspect of the study design. 
The treatment outcome assessors administering the HAMD, MADRS and HAMA scales will also 
be blind to the design of the study and the means of treatment assignment.  This blinding is 
necessary to prevent distortions of ratings accuracy due to expectations arising from knowledge 
that treatment is assigned based on the FDG-PET measurement.  
 
Debriefing 
Patients will be debriefed by the study team following their study participation outlining the 
reasons for the deception need of this study. 
 
Plans to inform participants of new findings or research results that might affect health 
 
 
If new findings emerge regarding risks or benefits of the study medications used in our 
study, patients will be informed of this information as soon as possible and reminded of their 
ability to continue participation in the study at their own will.   
 
Data and safety monitoring plan (DSMP) 
 
 
The proposed study is most appropriately considered the equivalent of a Phase IV 
clinical trial. The Departments of Psychiatry and Neurology Data Safety Monitoring Board will 
provide annual review of the safety and confidentiality components of the study. All serious 
adverse events will be reported to the DSMB within 10 days of learning of their occurrence, and 
any deaths will be reported within 24 hours. The DSMB includes physicians who are 
experienced in clinical research, a nurse, and administrative support. Statistical help is available 
as needed. Study clinicians serving on the DSMB will recuse themselves when the current 
studied is being reviewed by the DSMB. 
  
Plans for data management and monitoring 
 
  
Data will be collected and stored in a password-protected Microsoft Access database, on 
password-protected computers, stored in the MAP offices.
