Brief summary:
Background: Importance of chronic insomnia (CI) problem is determined by its high prevalence rate, comorbidity and resistance to the treatment. Although cognitive behavior treatment of insomnia (CBT-I) remains the recommended treatment for CI it has disadvantages of time consuming and low treatment response. Hence shortened and simplified behavioral approaches such as Brief Behavioral therapy of insomnia (BBT-I) are developed. The aim of the present study is to test the effectiveness of BBT-I program for chronic insomnia in comparison with zopiclone in Russian population. The anthropometric, psychological and polysomnographic characteristics of patients were measured to find predictors of effectiveness of each method.

Participants: 42 adults (14 males, 28 females, mean age 54 years) meeting the criteria for CI according International classification of sleep disorders-3 Methods: Participants were randomized into two groups. Each group passed 2-week courses of treatment by brief behavior treatment of insomnia (BBT-I) and zopiclone in different orders with 2-week washout period between the courses. Participants underwent in-lab polysomnography prior to the treatment and completed questionnaires (Insomnia Severity Index (ISI), Dysfunctional beliefs about sleep scale (DBAS), Beck Depression Inventory (BDI) and others) in the beginning and the end of each course

Detailed description:
The study had a crossover design implying that every patient underwent two different treatment courses in random sequence: hypnotic or structured educational program (BBT-I) delivered in two sessions.

Each treatment course was separated by 2-weeks washout period that provided the opportunity to evaluate the sustainability of treatment effect.

Before and after each treatment course and after each washout period subjects completed set of questionnaires.

The total duration of the study was 8 weeks in which 6 visits including 1 night polysomnography (PSG), 2 face-to-face structured educational program sessions and 5 diagnostic interviews have been performed.

Participants A sample of 42 adults (14 males, 28 females, mean age 54 years from 29 to 80 years) meeting the criteria for chronic insomnia according ICSD-3 was recruited from outpatient care of Department of sleep medicine of University Hospital №3 of I.M. Sechenov First Moscow State Medical University. All participants were informed about the nature, purpose, risks, and discomforts that could arise from their participation, and about their right to withdraw at any time. Subjects documented their willingness to participate by signing the informed consent form, approved by local Ethic Committee.

Treatment methods. BBT-I program includes two weekly one hour individual sessions; Hypnotic (zopiclone) in a dose of 7,5 mg has to be taken 30 minutes before bedtime for two weeks

Measures Questionnaires. During the first visit patients underwent structured clinical interview and filled in self-report questionnaires: Beck Depression Inventory (BDI), State-trait anxiety inventory (STAI), Toronto Alexithymia Scale - short version (TAS-20) , Big Five Questionnaire (BFQ-2R), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Dysfunctional beliefs about sleep scale (DBAS), Sleep hygiene index (SHI).

During the next 4 visits participants repeatedly underwent diagnostic tests included BDI, STAI, PSQI, ISI, DBAS, SHI.

Participants kept daily sleep diaries where they recorded bedtime and morning rise time, sleep onset latency (SOL), number of night awakenings and time of wakefulness after sleep onset before waking up (WASO) for the whole study period.

On the last visit participants completed questionnaire for assessment of effectiveness of treatment along with diagnostic routine. Patients were asked to rank the effectiveness of proposed methods of treatment (didactic presentation, stimulus control, sleep restriction, relaxing recording and zopiclone) in ascending order from 1 to 5 points (5 seems most effective).

Polysomnography. Participants underwent in-lab PSG (1 night without adaptation night) prior to the treatment in order to exclude other disorders producing subjective sleep complaints (sleep apnea, periodic limb movements disorder). Standard polysomnography montage including 6 monopolar electroencephalography (EEG) channels; 1 submental electromyogram (EMG) channel; 2 electrooculogram (EOG) channels; 2 EMG channels of the right and left tibialis anterior muscles; 1 electrocardiogram channel; oronasal airflow pressure; thoracic and abdominal efforts; respiratory sound; oxygen saturation; body position with videomonitoring was performed. The objective sleep measures included total sleep time (TST), sleep-onset latency, wake time after sleep onset (WASO), number of awakenings, sleep efficiency (the ratio of TST to time spent in bed multiplied on 100%, SE), percentage of sleep stages. PSG data were analysed according the 2007 American Academy of Sleep Medicine criteria including its revision in 2012.

Arms: arm 1: underwent the medication therapy (zopiclone) for the first two weeks followed by brief behavioral therapy arm 2: received two-week brief behavioral therapy followed by medication therapy (zopiclone).
Interventions: intervention 1: Brief behavioral therapy intervention 2: Zopiclone
Intervention descriptions: intervention 1: program included a question-and-answer part; a didactic presentation of sleep regulation mechanisms; the review of causes of onset and chronification of illness; an examination of patient's sleep log; explanation of sleep restriction method and prescription of individual regimen of sleep; explanation of stimulus control method; sleep hygiene education; discussion of relaxation techniques. Participants were supplied with 32 minute audio recording "Relaxation and refreshment session for insomnia" created for this study by Dr. A.Tabidze with verbal relaxing instructions with quiet musical composition behind it. Participants were instructed to listen to this recording in headphones each day for 2-week BBT-I period after laying into bed and turning the light off. intervention 2: zopiclone intake in a dose of 7,5 mg 30 minutes before bedtime for two weeks

STATISTICS
Primary Analysis Plan
Analysis of insomnia treatment will be conducted only for patients
matching inclusion and exclusion criteria who will complete at least
one treatment course (BBT-I or medication) and fill in questionnaires
prior and after the treatment. Continuous variables will be presented
in means and standard deviation (M±SD). Categorical and rank
variables will be presented as percentages.
Statistical significance of differences between group for continuous
variables will be evaluated with Student’s t-test after confirmation of
normal variable distribution by Kolmogorov-Smirnov test.
For continuous variables with distribution other than normal Mann-
Whitney U-test will be used. For comparison of the proportions
Pearson chi-squared test will be performed.
Criterion of response to the treatment is defined as the reduction of
ISI score reduction of >7 points from baseline. Remission criterion is
defined as final ISI score of 7 points or less. Nonresponse criterion is
defined as ISI score decrease of ≤7 points from baseline. Based on
these dichotomic values participants will be divided into two groups:
responders and nonresponders for each method of treatment.
Comparison of responders and nonresponders baseline quantitative
characteristics will be performed using Student’s t-test (for normal
data distribution) or Mann-Whitney U-test (for abnormal data
distribution). Statistical significance will be set at a p-value less 0,05.
Rationale for Number of
Subjects
Study design allows to compare two therapeutic approaches with a
relatively small sample size and to determine the predictors of
effectiveness for each treatment. Thus 40 patients get 2 therapeutic
approaches. This is the representative sample size enough to produce
normal variable distribution for further parameter statistical analysis.

PURPOSE OF THE INVESTIGATION
Name of investigational method
Brief behavioral therapy program
Imovan (zopiclone)
Intended use of the investigational method
2-week Brief behavioral therapy will be performed in two 1 hour session for treatment of
chronic insomnia (CI)
Imovan (zopiclone) in a dose of 7,5 mg has to be taken 30 minutes before bedtime for two
weeks
Overview of Clinical Studies
The main treatment approaches for chronic insomnia with proven efficacy are
pharmacologic and behavioral treatment. In accordance with the results of multiple
clinical trials and meta-analyses both methods have comparable effectiveness in
terms of sleep quality ranging between 64% (Buysse et.al., 2011) and 88% (Carson,
McDonagh, Thakurta, and Yen P. 2008).
GABA(a) agonists being the most widely used hypnotics could cause residual
daytime sedation and safety concerns like the risk of drug addiction, overdose and
intoxication along with cognitive toxicity, falls and hip fractures especially in
elderly persons (Pagel & Parnes, 2001)
The second approved treatment option for insomnia is cognitive-behavioral
treatment of insomnia combining behavioral and psychological techniques. Unlike
hypnotics this method has consistent long-term efficacy with few adverse effects
(Morin et.al., 2016). On the other hand it requires special training of therapist,
compliance of patient and noticeable time expenditures of both. Hence shortened
and simplified behavioral approaches have been developed. It includes brief
behavioral treatment for insomnia (BBT-I) lasting four weekly sessions instead of 6-
8, online sessions, telephone consultations, and self-help approaches. Although there
are no enough data for meta-analysis, BBT-I proved its efficacy in a number of
clinical comparative studies (Bootzin, 2004).
STUDY RATIONALE
Even after considering all the specific advantages and drawbacks of
pharmacological and cognitive-behavioral methods of CI treatment a clinician
would be still in question, which one would be preferable in a particular case.
There are still questions about the reason why CBT or pharmacotherapy or even
their combination didn’t reach 100% treatment response. So the treatment
response predictors identification is required for individualized treatment

Risk / Benefit Assessment
Brief behavioral therapy has no potential adverse effects, risks of addiction or tolerance.
Zopiclone has possible hypersensitivity adverse effects as well as possible effects on
central nervous system: taste disturbance; less commonly nausea, vomiting, dizziness,
drowsiness, dry mouth, headache; rarely amnesia, confusion, depression, hallucinations,
nightmares; very rarely light headedness, incoordination, paradoxical effects. Nevertheless
it remains medication recommended for insomnia treatment in accordance with
international guidelines
STUDY OBJECTIVES
Primary Objective
To test the effectiveness of short BBT-I program for chronic insomnia in comparison with
zopiclone in Russian population.
Secondary Objectives
Identification of anthropometric, psychological and polysomnographic predictors of
effectiveness of each method.
STUDY DESIGN
Study Overview
Prospective randomized crossover study. In accordance with this design every patient will
receive two different treatment courses in random sequence: zopiclone or structured
educational program (BBT-I) delivered in two sessions. Patients of the zopiclone-first
group will receive the medication therapy for the first two weeks followed by educational
program. Patients of the BBT-I-first group will receive two-week educational program
followed by medication therapy.
Each treatment course will be separated by 2-weeks washout period that will provide the
opportunity to evaluate the sustainability of treatment effect.
The total duration of the study will be 8 weeks with 6 visits including 1 night
polysomnography (PSG), 2 face-to-face structured educational program sessions and 5
diagnostic interviews. Total duration of the study will be 2 years.
Criteria for evaluation
Primary Efficacy Endpoint
Proposed primary efficacy endpoint is change of insomnia severity index
(ISI) after treatment. Criterion of response to the treatment will be defined as the
reduction of ISI score reduction of >7 points from baseline. This criterion is
indicative of moderate improvement and validated as clinically significant
(Morin, Belleville & Belanger, 2011). Remission criterion will be defined as final


Protocol 1
Confidential
Page 12 of 26
ISI score of 7 points or less. Nonresponse criterion will be defined as ISI score
decrease of ≤7 points from baseline.
Secondary Efficacy Endpoints
1. Insomnia severity index self reported insomnia symptoms severity . Each item is
scored 0 (no problem) - 4 (very big problem) with total between 0-28 (absence of
insomnia (0-7); sub-threshold insomnia (8-14); moderate insomnia (15-21); and
severe insomnia (22-28).
2. Beck Depression Inventory. 21-item questionnaire assessing (on 4-point Likert
scales) the intensity of depressive symptoms in the past week
3. State-trait anxiety inventory. 2-part questionnaire assessing state (situational) and
trait anxiety. Both situational and trait parts comprise 20 items rated on a 4-point
Likert scale.
4. Dysfunctional beliefs about sleep scale. questionnaire assessing sleep related
cognitions in 16 item rated on a 10-point Likert scale.
5. Sleep hygiene index. questionnaire assessing sleep related behavior in 13 item
rated on a 5-point Likert scale.
6. Pittsburg Sleep Quality Index. 19-item questionnaire evaluating sleep quality over
the past month. The first 4 items are open questions, items 5 to 19 are rated on a 4-
point Likert scale. A total score range from 0 to 21. A score > 5 suggests poor
sleep quality.
7. Big Five Questionnaire. questionnaire assessing personal traits in 134 item rated
on a 5-point Likert scale.
8. Toronto alexythymia scale, short version (TAS-20) - questionnaire assessing
alexythymia in 20 item rated on a 5-point Likert scale.
9. β-adrenoreactivity test - laboratory peripheral blood sample analysis for
evaluation of sympathetic activity
10. Polysomnography. the main variables used were sleep latency, total sleep time,
sleep efficiency, wake after sleep onset, number of awakenings, sleep stages
proportion
Safety Evaluations
All subjects will be asked about well-being and possible adverse effects of treatment, on
each biweekly visit. In the case of condition exclusionary for study participation
(exacerbation of disease, starting medicines, incompatible with zopiclone etc.) when it is
not in the subject’s best interest to continue the subject may be discontinued from study

DISCONTINUATION AND REPLACEMENT OF SUBJECTS
Early Discontinuation of Study
A subject may be discontinued from study treatment at any time if the subject or the
investigator, feels that it is not in the subject’s best interest to continue.  The following is a
list of possible reasons for study treatment discontinuation:

Subject withdrawal of consent (or assent)

Subject had a condition exclusionary for study participation

Subject is not compliant with study procedures

Adverse event that in the opinion of the investigator would be in the best interest of the
subject to discontinue study treatment
If a subject is withdrawn from treatment due to an adverse event, the subject will be
followed and treated by the Investigator until the abnormal parameter or symptom has
resolved or stabilized.
All subjects who discontinue study treatment will be recommended to come in for an early
discontinuation visit as soon as possible and then will be encouraged to complete all
remaining scheduled visits and procedures.
All subjects are free to withdraw from participation at any time, for any reason, specified
or unspecified, and without prejudice.
Reasonable attempts will be made by the investigator to provide a reason for subject
withdrawals.  The reason for the subject’s withdrawal from the study will be specified in
the subject’s CRF. Subjects withdrawn after Visit 5 but prior to Visit 6 will be encouraged
to come in for a final visit (pass the procedures supposed for their next scheduled visit).
Replacement of Subjects
Subjects withdrawn from the study treatment will be replaced. Subjects withdrawn from
the study after Visit 5 but prior to Visit 6 won’t be replaced.
Protocol Violations
Protocol violations for this study include, but are not limited to, the following:

Failure to meet inclusion/exclusion criteria


Protocol 1
Confidential
Page 20 of 26

Use of a prohibited concomitant medication

Non-compliance with study drug regimen, and questionnaires completion
Failure to comply with Good Clinical Practice (GCP) guidelines will also result in a
protocol violation. If a protocol violation occurs, a Protocol Violation Form detailing the
violation will be generated.
DATA SAFETY MONITORING
There will be no data monitoring committee
STATISTICAL METHODS AND CONSIDERATIONS
A Statistical Analysis Plan (SAP) is written describing all analyses that will be performed.
Data Sets Analyzed
All subjects matching inclusion and exclusion criteria who will complete at least one
treatment course (BBT-I or medication) and fill in questionnaires prior and after the
treatment will be included in the safety analysis.
Demographic and Baseline Characteristics
The following demographic variables at screening will be summarized by dose level:
gender, age, height and weight. Continuous variables will be presented in means and
standard deviation (M±SD).
Analysis of Primary Endpoint
Statistical significance of differences between ISI level before and after treatment for both
treatment methods will be evaluated with Student’s t-test after confirmation of normal
variable distribution by Kolmogorov-Smirnov test. For continuous variables with
distribution other than normal Mann-Whitney U-test will be used. For comparison of the
proportions Pearson chi-squared test will be performed.
Criterion of response to the treatment is defined as the reduction of ISI score reduction of
>7 points from baseline. This criterion is indicative of moderate improvement and
validated as clinically significant (Morin, Belleville & Belanger, 2011). As well the
criterion corresponds to approximately 1 standard deviation of the pretreatment values
(Cohen effect size of approximately 1.0). Remission criterion is defined as final ISI score
of 7 points or less. Nonresponse criterion is defined as ISI score decrease of ≤7 points
from baseline.
Analysis of Secondary Endpoints
Statistical significance of differences between BDI, STAI, PSQI, DBAS, SHI, β-
adrenoreactivity level, sleep diary data before and after treatment for both treatment
methods will be evaluated with Student’s t-test after confirmation of normal variable
distribution by Kolmogorov-Smirnov test. For continuous variables with distribution


Protocol 1
Confidential
Page 21 of 26
other than normal Mann-Whitney U-test will be used. For comparison of the proportions
Pearson chi-squared test will be performed.
Based on the response criterion participants will be divided into two groups: responders
and nonresponders for each method of treatment. Comparison of responders and
nonresponders baseline quantitative characteristics (polysomnographic, antropometric,
psychometric) will be performed using Student’s t-test (for normal data distribution) or
Mann-Whitney U-test (for abnormal data distribution). Statistical significance will be set
at a p-value less 0,05.
Safety and tolerability data will be summarized by treatment group. Adverse events will
be tabulated by treatment group and include the number of patients for whom the event
occurred, the rate of occurrence, and the severity and relationship to study drug.
Interim Analysis
Interim statistical analysis will be performed after 20 patients complete the study
protocol.
Sample Size and Randomization
The number of subjects planned to be enrolled is 40. This is a representative sample for
study of treatment effects. The crossover design of the study will allow us to compare two
therapeutic approaches with a relatively small sample size and to determine the predictors
of effectiveness for each treatment.

Information for Patient
Dear patient
You are invited to take part in the research in the study " Effectiveness of nonspecific
methods of treatment and Zopiclone for chronic insomnia"
The research is conducted by the post-graduate student, neurologist Pchelina Polina under
the direction of assistant professor of the Department of Nervous Diseases of the IPO of the I.M.
Sechenov First Moscow State Medical University, Poluektov Mikhail Gurievich.
Please read this document carefully, it contains information about the study and possible
risks. You may ask any questions concerning this research and have those questions answered
before agreeing to participate in or during the study. Or you may contact the investigator(s) at the
phone numbers below.
Your signature certifies that you have decided to participate having read and understood
the information presented. You will be given a copy of this consent form to keep.
You are invited to participate in this research, because your complaints meet the criteria for
chronic insomnia, and you have not taken medications that have a sleeping pills during the last
week
This research project will aim to determine the effectiveness of non-drug therapy in
comparison with the hypnotic for the treatment of chronic insomnia.
Upon receipt of your informed consent for participation and inclusion in the study, your
general and neurological status will be assessed and you will be asked to complete set of
questionnaires to evaluate your psychological status, personal traits and extent of sleep disorders.
Then you will be asked to have blood test for assessment of the sympathetic hyperactivation
degree and 1 night in-lab polysomnography for evaluation of objective sleep time.
After the initial examination, you will be randomly assigned to one of two groups, in each
of which you will receive treatment for chronic insomnia first by one method, then by another.
The sequence of methods will be random.
The first method consists in a standard insomnia treatment with the hypnotic Zopiclone
(Imovan) 7.5 mg taken 30 minutes before bedtime for 2 weeks.
The second approach of treatment is structured educational method for the treatment of
chronic insomnia combining educational and behavioral methods: doctor will discuss healthy
sleep, the causes of its disorders and the methods of nonpharmacological treatment prescribe
your individual sleep-wake regimen and give you individual recommendations for improvement
of your sleep. This method consists of 2 individual sessions lasting 1 hour, 1 time per week.
After first session, you will be provided with reminder card containing basic information, flash
players with relaxation audio recording facilitating falling asleep. It is expected that you will
follow the doctor's recommendations on the regimen and hygiene of sleep, listen to the audio
recording during the two-week treatment period.


After the first treatment course you will be asked to complete the complex of diagnostic
procedures (questionnaires, blood sampling) - to evaluate the effectiveness of therapy (Week 2,
Month 1).
After the first treatment course, a two-week break followed by complex of diagnostic
procedures (questionnaires, blood sampling) are planned - to monitor the effectiveness of therapy
dynamically (Week 6, Month 2).
After the two-week break you will get another treatment method for two weeks (if the first
one was zopiclone then second one will be structured educational method vice versa) followed
by complex of diagnostic procedures (questionnaires, blood sampling)
After the second treatment course, a two-week break followed by complex of diagnostic
procedures (questionnaires, blood sampling) are planned - to monitor the effectiveness of therapy
dynamically (Week 8, Month 2).
You will be asked to keep a diary of sleep 1 week before the start of the first course of
treatment, and for the both treatment courses and break ups.
The duration of your participation in the study will be 8 weeks, 6 visits are expected,
including two individual sessions with a doctor for 1 hour, one night polysomnography study, 5
questionnaires to assess the psychological status, the nature and extent of sleep disorders, and 5
Finger blood sampling for assessing the degree of sympathetic hyperactivation.
Possible benefits to you as a research participant involve a detailed study of your physical,
neurological and psychological state to adjust individual therapy for you.
Possible discomforts associated with the research participation: the time spent on night
polysomnography, filling out questionnaires and questionnaires, attending individual sessions
with a doctor.
Possible risks associated with research participation is connected to blood sampling from
the finger. The risk is minimal, since manipulation is done in aseptic conditions by trained
personnel
No additional costs are foreseen for you.
Your participation in the study can be terminated when the doctor feel that it was not in
your best interest to continue.  The following is a list of possible reasons for study treatment
discontinuation:

Your withdrawal of consent (or assent)

You have a condition exclusionary for study participation (acute disease,
exacerbation of chronic disease, pregnancy etc.)

