STUDY SYNOPSIS 
Title: A Phase 3, multicenter, randomized, double-blind, placebo-controlled study to assess the efficacy, 
safety, and tolerability of AVP-786 (deuterated [d6]-dextromethorphan hydrobromide [d6-DM]/quinidine 
sulfate [Q]) for the treatment of agitation in patients with dementia of the Alzheimer’s type. 
Study Objectives 
The objectives of the study are to evaluate the efficacy, safety, and tolerability of AVP-786 compared to 
placebo, for the treatment of agitation in patients with dementia of the Alzheimer’s type.   
Study Population 
Number of Patients:  Approximately 470 patients will be enrolled at approximately 75 centers in North 
America. 
Condition/Disease:  Patients with agitation secondary to dementia of the Alzheimer’s type.  The diagnosis 
of probable Alzheimer’s disease will be based on the ‘2011 Diagnostic Guidelines for Alzheimer’s 
Disease’ issued by the National Institute on Aging (NIA)-Alzheimer’s Association (AA) workgroups.1  
Diagnosis of agitation will be based on the provisional consensus definition of agitation in patients with 
cognitive disorders developed by the International Psychogeriatric Association (IPA) Agitation Definition 
Work Group.2  
Key Inclusion Criteria:  Patients with clinically significant, moderate/severe agitation at the time of 
screening and for at least 2 weeks prior to randomization, that interferes with daily routine and for which 
a prescription medication is indicated in the opinion of the investigator.  A Clinical Global Impression of 
Severity of Illness scale for Agitation (CGIS-Agitation) score of ≥ 4 (moderately ill) at screening and 
baseline is required for study participation.  Eligible patients must have a reliable caregiver who is able 
and willing to comply with study procedures, including not administering any prohibited medications 
during the course of the study.   
Key Exclusion Criteria:  Patients with dementia predominantly of the non-Alzheimer’s type (e.g., 
vascular dementia, frontotemporal dementia, Parkinson’s disease, substance-induced dementia) and 
patients with symptoms of agitation that are not secondary to Alzheimer’s disease (e.g., secondary to 
pain, other psychiatric disorder or delirium) are not eligible. 
A complete list of inclusion/exclusion criteria is presented in Section 4 of the study protocol. 
Study Design 
Structure: This is a phase 3, multicenter, randomized, double-blind, placebo-controlled study.   
Duration: Patients will be enrolled in the study for approximately 16 weeks; with up to 4-week screening 
period and 12-week treatment period.   
Study Treatment:  The investigational product is AVP-786 (deuterated [d6]-dextromethorphan 
hydrobromide [d6-DM; INN:deudextromethorphan]/quinidine sulfate [Q]).  Three doses of AVP-786 will

be used in the study, d6-DM 18 mg/Q 4.9 mg, d6-DM 28 mg/Q 4.9 mg and d6-DM 42.63 mg/Q 4.9 mg, 
hereafter referred to as AVP-786-18/4.9, AVP-786-28/4.9, and AVP-786-42.63/4.9, respectively.  
Control:  Placebo capsules of identical appearance to study medication will be used as control. 
Randomization/Stratification:  Eligible patients will be randomized into the study to either AVP-786-
28/4.9, AVP-786-42.63/4.9, or placebo group.  The randomization will be stratified by the 
Neuropsychiatric Inventory (NPI) Agitation/Aggression domain score (≤ 6 vs. > 6), risk assessment for 
falls (normal/mild vs. moderate/severe), and concomitant use of antipsychotic medications (yes vs. no).    
Dose Regimen: Eligible patients will be randomly assigned at the Baseline visit to receive AVP-786 or 
matching placebo capsules.  Study medication will be administered orally twice daily (BID, 1 capsule in 
the morning and 1 capsule in the evening approximately 12 hours apart) throughout the study.  
Patients randomized to the AVP-786-28/4.9 group will start with AVP-786-18/4.9 once a day in the 
morning and placebo in the evening for the first 7 days of the study.  From Day 8, patients will receive 
AVP-786-18/4.9 BID for 14 days.  From Day 22, patients will receive AVP-786-28/4.9 BID for the 
remaining 9 weeks of the study.  If deemed necessary by the investigator, a one-time downward dose 
adjustment to AVP-786-18/4.9 will be allowed after Visit 3 up to and including Visit 4 (ie, Day 23 to Day 
43), and the patient will remain on the lower dose of study medication for the remaining study duration.  
Patients requiring a dose-adjustment between study visits will need to have an unscheduled visit to 
perform safety assessments.   
Patients randomized to the AVP-786-42.63/4.9 group will start with AVP-786-28/4.9 once a day in the 
morning and placebo in the evening for the first 7 days of the study.  From Day 8, patients will receive 
AVP-786-28/4.9 BID for 14 days.  From Day 22, patients will receive AVP-786-42.63/4.9 BID for the 
remaining 9 weeks of the study.  If deemed necessary by the investigator, a one-time downward dose 
adjustment to AVP-786-28/4.9 will be allowed after Visit 3 up to and including Visit 4 (ie, Day 23 to Day 
43), and the patient will remain on the lower dose of study medication for the remaining study duration.  
Patients requiring a dose-adjustment between study visits will need to have an unscheduled visit to 
perform safety assessments. 
Patients will have at least a 
 chance of receiving AVP-786 at some point during the study. 
Assessments and Visits  
Patients will attend clinic visits at Screening, Baseline (Day 1), and on Days 8 (Week 1), 15 (Week 2), 
22 (Week 3), 43 (Week 6), 64 (Week 9), and 85 (Week 12).  Patients who terminate early will receive 
daily phone calls for 5 consecutive days following the early termination (ET) visit to query on their 
overall well-being and will be asked to return for an in-clinic Follow-up visit 30 days after last dose of 
study medication for selected safety and efficacy assessments.  Safety follow-up phone calls will be made 
on Days 29 (Week 4) and 71 (Week 10).  Study procedures will be performed at each visit as outlined in 
the Schedule of Evaluations and Visits (Table 1).

Response Measures 
Efficacy  
Primary measure: Primary efficacy will be assessed using the Cohen-Mansfield Agitation Inventory 
(CMAI).  
Secondary measures:  Secondary efficacy measures include: Agitation/Aggression domain of the NPI, 
modified Alzheimer’s Disease Cooperative Study Clinical Global Impression of Change (mADCS-CGIC-
Agitation), NPI-Agitation/Aggression domain Caregiver Distress score, NPI-Aberrant Motor Behavior 
domain, Zarit Burden Interview (ZBI), NPI-Irritability/Lability domain, Patient Global Impression of 
Change (PGIC-rated by caregiver), Dementia Quality of Life (DEMQOL), Cornell Scale for Depression 
in Dementia (CSDD), Resource Utilization in Dementia (RUD), total NPI, ADCS-CGIC-Overall, CGIS 
Agitation, Alzheimer’s Disease Assessment Scale-Cognitive Subscale (ADAS-cog), and General Medical 
Health Rating (GMHR). 
For consistency of rating, assessments should be performed, whenever possible, by the same rater 
throughout the study.  The following scales MUST be administered by the same rater at each visit:  
CMAI, NPI, mADCS-CGIC-Agitation, and CGIS-Agitation. 
Pharmacokinetics 
Plasma concentrations of d6-DM, its metabolites, and Q will be measured. 
Safety and Tolerability  
Safety and tolerability of AVP-786 will be assessed by reported adverse events (AEs), physical and 
neurological examinations, vital signs, clinical laboratory assessments, resting 12-lead electrocardiograms 
(ECGs), Sheehan Suicidality Tracking Scale (S-STS), Mini Mental State Examination (MMSE), Timed 
Up and Go (TUG) test, and the Epworth Sleepiness Scale (ESS).  
Pregnancy tests will be conducted for females of childbearing potential.  
General Statistical Methods and Types of Analyses 
Analysis Populations 
Three analysis populations will be used; modified intent-to-treat (mITT), intent-to-treat (ITT), and safety.  
The mITT population includes all patients randomized in the study who had at least one post-baseline 
efficacy assessment, and will be used for all analyses of efficacy.  Patients in the mITT population will be 
included in the treatment group to which they were randomized regardless of treatment received.  The 
ITT population includes all randomized patients in the study, and will be used for exploratory efficacy 
analyses.  The safety population includes all patients who received study treatment, and will be used for 
all analyses of safety.  Patients will be included in the treatment group based on the actual treatment 
received.

Efficacy Analyses  
The primary efficacy endpoint is the change from Baseline to Week 12 (Day 85) in the composite CMAI 
scores.  The primary treatment comparisons (AVP-786-42.63/4.9 vs. placebo and AVP-786-28/4.9 vs. 
placebo) will be performed by using a linear mixed effects model repeated measures (MMRM) with 
comparisons being made between the patients treated with AVP-786 and patients treated with concurrent 
placebo.  The model will include fixed effects for treatment, visit, treatment-by-visit interaction, baseline-
by-visit interaction, and baseline covariates which include baseline value and other factors as appropriate.  
An unstructured covariance model will be used.   
A gate-keeping procedure will be used to control the overall type I error at 2-sided α = 0.05 for the 2 
primary treatment comparisons (AVP-786-42.63/4.9 vs. placebo and AVP-786-28/4.9 vs. placebo). 
Specifically, the comparison between AVP-786-42.63/4.9 vs. placebo will be performed first at the 
significance level of 0.05.  If the comparison is statistically significant, the comparison between 
AVP-786-28/4.9 vs. placebo will be performed at the same significance level. 
Secondary efficacy endpoints include change from Baseline to Week 12 (Day 85) for the following 
efficacy measures: mADCS-CGIC-Agitation, NPI-Agitation/Aggression domain score and Caregiver 
Distress score, NPI-Aberrant Motor Behavior domain, ZBI, NPI-Irritability/Lability domain, PGIC, 
DEMQOL, CSDD, RUD, total NPI, ADCS-CGIC-Overall, CGIS-Agitation, ADAS-cog, and GMHR.   
Safety Analyses 
Safety measures will be summarized by treatment group.   
Sample Size Calculation 
Power calculation was performed assuming a normal distribution for the primary efficacy endpoint.  
 
 
 
  
 
  
The study protocol is amended to include another dose arm (AVP-786-42.63/4.9) with 140 patients in the 
treatment arm, when approximately 100 patients have already been enrolled (50 AVP-786 28/4.9 and 50 
placebo) in the study.  To maintain an approximate 
chance for an incoming patient to receive active 
drug, the sample size for the placebo treatment group is amended to 190.  Overall, the total sample size of 
470 patients will include 140 patients for AVP-786 28/4.9 and AVP-786 42.63/4.9 groups each and 190 
patients in the placebo group.  This sample size will provide approximately 
 power to detect a 
treatment effect size of 
between AVP-786 42.63/4.9 and concurrent placebo treatment group.

study of AVP-923 (dextromethorphan/quinidine combination) for the treatment of agitation in AD 
(Study 12-AVR-131). 
d6-DM binds to receptors responsible for modulation of glutamate, monoamine, sigma-1, and nicotinic 
cholinergic pathways that may be key to CNS therapeutics.  Pharmacology studies conducted by Avanir 
with d6-DM have demonstrated that deuteration does not alter the basic pharmacology of DM.  
Pharmacokinetic (PK) and drug metabolism studies indicate that d6-DM is metabolized by the same 
metabolic pathways as DM, but that deuteration results in a decreased rate of metabolism by CYP2D6.   
The recently completed Phase 2 Study 12-AVR-131 met the primary efficacy endpoint and showed clear 
improvement of agitation in patients receiving AVP-923 compared with placebo.  Study 12-AVR-131 
was a 10-week, randomized, double-blind, placebo-controlled, 2-stage, sequential parallel comparison 
design (SPCD) study to assess the efficacy, safety, and tolerability of AVP-923 for the treatment of 
symptoms of agitation in 220 patients with AD.  Patients who received AVP-923 had significantly 
reduced agitation compared to patients who received placebo (p<0.001) as measured by the 
Agitation/Aggression domain of the Neuropsychiatric Inventory (NPI).  The majority of the secondary 
endpoints studied (e.g., NPI-total, NPI-Agitation/Aggression domain Caregiver Distress, Clinical Global 
Impression of Change [CGIC]-Agitation, Clinical Global Impression of Severity [CGIS]-Agitation and 
Patient Global Impression of Change [PGIC]) were also statistically significant.  Both clinician and 
patient/caregiver impressions of change corroborated the clinical meaningfulness of improvements 
observed in agitation.  Numerically favorable response in cognition as measured by the Mini Mental State 
Examination (MMSE) and the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) 
were observed but neither achieved statistical significance.   
Studies conducted by Avanir have shown that d6-deuterium modification of DM reduced the rate of 
CYP2D6 metabolism such that combination with a significantly lower dose of quinidine (< 50% of the 
amount of Q contained in AVP-923) was sufficient for bioequivalence of d6-DM to DM in AVP-786 and 
AVP-923, respectively (Studies 12-AVR-132, 13-AVR-134, 14-AVP-786-101, and 14-AVP-786-102).  
The lower amount of Q in AVP-786 may reduce interactions with other CYP2D6 substrates, limit Q 
levels even in the presence of CYP3A4 inhibitors, and reduce the effects on cardiac repolarization and 
QTc interval.  
The receptor pharmacology of d6-DM and the robust clinical effect observed in Study 12-AVR-131 
suggest AVP-786 may have a benefit in agitation, while the significantly lower dose of Q in AVP-786 
may lead to improvement in the safety profile compared with AVP-923.  Combined, the potential efficacy 
and safety of AVP-786 warrant further clinical investigation.  The current study (Study 15-AVP-302) is 
designed to evaluate the efficacy, safety, and tolerability of AVP-786 for the treatment of agitation in 
patients with dementia of the Alzheimer’s type. 
1.2 
Rationale for the Study Design 
The randomized, placebo-controlled, double-blind design reduces sources of bias that are inherent in less 
well-controlled designs.  The safety assessments used are standard in clinical research and are generally 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 29 
 
recognized as reliable, accurate, and relevant.  The rating scales used to assess efficacy are well-
established instruments that are widely used in clinical studies of AD. 
1.3 
Rationale for AVP-786 Dose 
The planned doses of AVP-786 for this study initially were d6-DM 28 mg/Q 4.9 mg and d6-DM 
18 mg/Q 4.9 mg, hereafter referred to as AVP-786-28/4.9 and AVP-786-18/4.9, respectively.  The 
AVP-786-28/4.9 dose is achieved by gradual titration schedule starting with AVP-786-18/4.9.  The study 
protocol is amended to include an additional treatment arm with a dose of d6-DM 42.63 mg/Q 4.9 mg 
(AVP-786-42.63/4.9) achieved by gradual titration with AVP-786-28/4.9 using the same titration 
regimen. 
 
 
 
 
 
 
 
 
  
 
 
 
1.4 
Rationale for the Duration of Dosing 
A drug being developed for treatment of a chronic condition needs to show maintenance of effect.  A 
12-week treatment duration is generally considered by experts and regulators as a reasonable time frame 
to assess acute and chronic effects and safety of a compound for chronic use.  To ensure tolerability, 
patients allocated to the study treatment (AVP-786) will gradually be exposed to the assigned dose; 
beginning with once-daily dosing of a dose lower than the assigned dose for one week, followed by twice-
daily dosing of the same dose for 2 weeks, and then twice-daily dosing of the assigned dose (AVP-786-
28/4.9) for the remaining study duration.  
 
  
Thus, patients assigned to AVP-786-28/4.9 will receive AVP-786-18/4.9 once daily for one week, 
followed by AVP-786-18/4.9 twice daily for 2 weeks and then AVP-786-28/4.9 for the remaining study 
duration, with a provision for a one-time down titration to AVP-786-18/4.9, whereas patients assigned to 
AVP-786-42.63/4.9 will receive AVP-786-28/4.9 once daily for one week, followed by AVP-786-28/4.9 
twice daily for 2 weeks and then AVP-786-42.63/4.9 for the remaining study duration, with a provision 
for a one-time down titration to AVP-786-28/4.9 during the study.

STUDY DESIGN 
This is a phase 3, multicenter, randomized, double-blind, placebo-controlled study of 12-week treatment 
duration.   
Approximately 470 patients will be enrolled at approximately 75 centers in North America.  There will be 
8 scheduled clinic visits including a screening visit, and 2 safety follow-up phone calls in this study.  
Patients will attend clinic visits at Screening, Baseline (Day 1), and on Days 8 (Visit 2/Week 1), 
15 (Visit 2.1/Week 2), 22 (Visit 3/Week 3), 43 (Visit 4/Week 6), 64 (Visit 5/Week 9), and 85 (Visit 
6/Week 12).  Patients who terminate early will receive daily phone calls for 5 consecutive days following 
the ET visit to query on their overall well-being and will be asked to return for an in-clinic Follow-up 
visit 30 days after last dose of study medication for selected safety and efficacy assessments. Patients who 
do not roll over to the extension study (Study 15-AVP-786-303) will receive a safety follow-up phone 
call 30 days after the last dose of study medication.  Safety follow-up phone calls will be made on Days 
29 (Week 4) and 71 (Week 10).  Study procedures will be performed at each visit as outlined in the 
Schedule of Evaluations and Visits (Table 1). 
Eligible patients will be randomly assigned at the Baseline visit to receive AVP-786 or matching placebo.  
Study medication will be administered orally twice daily from Day 1 through Day 85.  Patients (or 
caregivers) will self-administer study medication on all study days except on applicable clinic-visit days 
when patients will be administered their morning dose of study medication at the clinic in the presence of 
site personnel, regardless of the time of day.  Screening will occur within 4 weeks prior to randomization.   
Following screening procedures for assessment of inclusion and exclusion criteria, eligible patients will 
be randomized into the study to either the AVP-786-28/4.9, AVP-786-42.63/4.9, or placebo group.  The 
randomization will be stratified by the NPI Agitation/Aggression domain score (≤ 6 vs. > 6), risk 
assessment for falls (normal/mild vs. moderate/severe), and concomitant use of antipsychotic medications 
(yes vs. no).  Study medication (active or placebo) will be administered orally BID (1 capsule in the 
morning and 1 capsule in the evening approximately 12 hours apart) throughout the treatment period. 
Patients randomized to the AVP-786-28/4/9 group will start with AVP-786-18/4.9 once a day in the 
morning and placebo in the evening for the first 7 days of the study.  From Day 8, patients will receive 
AVP-786-18/4.9 BID for 14 days.  From Day 22, patients will receive AVP-786-28/4.9 BID for the 
remaining 9 weeks of the study.  If deemed necessary by the investigator, a one-time downward dose 
adjustment to AVP-786-18/4.9 will be allowed after Visit 3 up to and including Visit 4 (ie, Day 23 to Day 
43), and the patient will remain on the lower dose of study medication for the remaining study duration.  
Patients requiring a dose-adjustment between study visits will need to have an unscheduled visit to 
perform safety assessments.

STUDY POPULATION 
Patients enrolled in this study must have a diagnosis of probable AD and must present with clinically 
meaningful, moderate/severe agitation secondary to AD.  
The diagnosis of probable AD will be based on the ‘2011 Diagnostic Guidelines for Alzheimer’s Disease’ 
issued by the National Institute on Aging (NIA)-Alzheimer’s Association (AA) workgroups.1  These new 
criteria were developed based on the review of the NINCDS–ADRDA criteria.18  Neither AD nor 
agitation should be explainable by delirium, substance use and/or major psychiatric disorders.  
The provisional consensus definition of agitation in patients with cognitive disorders developed by the 
Agitation Definition Work Group (ADWG) from the International Psychogeriatric Association (IPA),2  
will be used for selecting study patients.  This proposed definition is limited to patients with cognitive 
impairment and requires:  (a) evidence of emotional distress; (b) one of 3 observable types of behaviors-
excessive motor activity, verbal aggression, or physical aggression; (c) that the behavior causes excess 
disability; and (d) that the behaviors cannot be solely attributable to a suboptimal care environment or 
other disorder such as a psychiatric illness, a medical illness, or effects of a substance.  
Eligible patients must have agitation (persistent or frequently recurrent) at the time of study screening and 
for at least 2 weeks prior to randomization and the agitation symptoms must be severe enough such that 
they interfere with daily routine and cause distress to the patient and caregiver for which a prescription 
medication is deemed indicated, in the opinion of the treating physician. 
Agitation will further be assessed using the CGIS-Agitation scale (0-7).  A score of ≥ 4 (moderately ill) at 
screening and baseline are required for study participation. 
Eligible patients are to have otherwise acceptable and stable general health as required by the study 
protocol, and documented by medical history, physical examination, electrocardiogram (ECG), and 
clinical laboratory examinations. 
Eligible patients must have a caregiver who is able and willing to comply with all required study 
procedures, ensuring that the patient attends all study visits and takes the study medication as instructed.  
Caregivers will also be instructed to keep a study diary, to report any changes in patient’s status, 
including adverse events, standard of care setting (e.g., becoming a resident in an assisted living facility), 
and to provide their impression and assessment regarding the investigational treatment.  In order to 
qualify as a reliable informant (i.e., caregiver) capable of assessing changes in the patient’s condition 
during this study, the individual must spend a minimum of 2 hours per day for 4 days per week with the 
study patient.

Patient Withdrawal From the Study 
Patients and caregivers will be advised verbally and in the written ICF that they have the right to 
withdraw from the study at any time without prejudice or loss of benefits to which they are otherwise 
entitled.  The investigator or sponsor may discontinue a patient from the study in the event of an 
intercurrent illness, adverse event, other reasons concerning the health or well-being of the patient, or in 
the case of lack of cooperation, non-compliance, protocol violation, or other administrative reasons.  If a 
patient does not return for a scheduled visit, every effort should be made to contact the patient.  
Regardless of the circumstance, every effort should be made to document patient outcome, if possible.  
The investigator should inquire about the reason for withdrawal, request the caregiver return all unused 
investigational product (IP), and follow-up with the patient regarding any unresolved adverse events.  
 
 
 
Patients who terminate early will be asked to return to the clinic to complete the Visit 6 assessments and 
an in-clinic Follow-up visit, 30 days after last dose of study medication for selected safety and efficacy 
assessments.  In addition, daily phone calls for 5 consecutive days following ET visit will be made for 
these patients to assess their overall well-being.

If the patient withdraws from the study, and consent is withdrawn by the caregiver and/or patient’s 
representative for disclosure of future information, no further evaluations should be performed, and no 
additional data should be collected.  The sponsor may retain and continue to use any data collected before 
such withdrawal of consent.  Patients who withdraw from the study will not be replaced.

Packaging 
The investigators will be supplied with pre-labeled, individually pre-packaged and tamper-proof sealed 
blister cards.  Each panel of the blister card (1 week of study medication) consists of 2 rows of blister 
strips, one row for the morning dose and one row for the evening dose (Figure 1).  Each blister card will 
contain 3 panels, providing sufficient study medication for 3 weeks of treatment and an additional 3 days 
of supply (total of 48 capsules).

5.1.4 
Labeling 
All labels will contain protocol number, product name, blister card number, an investigational drug 
warning, and dosage instructions to take 1 capsule in the morning and 1 capsule in the evening, storage 
conditions, and company name.  The blister card label will consist of 2 panels, with 1 detachable panel 
that will be removed and affixed to the study medication Dispensing Log page at the time of dispensing.  
Space is provided on both panels of the card label to record Patient Number, the Visit Week, and 
Dispensing Date.  All investigational product labels comply with all applicable federal and local 
regulations.  
5.1.5 
Storage of Clinical Supplies 
Clinical supplies must be stored in compliance with label requirements in a secure place and kept at room 
temperature; 25°C (77°F) with excursions permitted to 15°C to 30°C (59°F-86°F).

5.1.6 
Study Medication Administration 
All patients will receive study medication according to the blister card numbers assigned by an interactive 
web response system (IWRS) randomization scheme.  Designated staff at each site will dispense study 
medication.  Study medication should be administered to the patient by the caregiver, family member, 
nursing home staff, or self-administered with supervision, except on applicable clinic visit days when 
patients will be administered their dose of study medication at the clinic in the presence of site personnel, 
regardless of the time of day.  Patients and caregivers will be instructed that the patient should take the 
study medication orally with water approximately every 12 hours ± 4 hours (morning and evening).  The 
time the patient takes each dose of medication should be recorded in the diary card.  For Visits 2 (Day 8) 
and 2.1 (Day 15), caregivers should be advised that the patient should take the morning dose of study 
medication within 2 hours of the clinic appointment.  Patient’s missed doses will be noted in the 
electronic case report form (eCRF).  All study medication will be supplied and administered in a double-
blind manner throughout the entire duration of the study. 
5.2 
Accountability of Study Supplies 
5.2.1 
Receipt of Supplies 
The investigator is responsible for maintaining an inventory of each shipment of IP received and 
comparing it with the accompanying Drug Accountability Report/Material Shipping Form.  The 
investigator will verify the accuracy of the information on the form, sign and date it, and return the form 
to the sponsor or its representative.  All IP supplied is for use only in this study and should not be used for 
any other purpose.  All blister card material ID numbers will also be recorded and tracked at the site using 
the Drug Accountability Log. 
5.2.2 
Record of Dispensing 
Accurate recording of all IP dispensing for individual patients will be made in the appropriate section of 
the patient’s eCRF.  This eCRF will contain the following information: (i) the initials and patient number 
to whom the drug was dispensed; (ii) the date(s) and quantity of the drug dispensed to the patient; and 
(iii) the blister card material ID number assigned to the patient via IWRS.  
Additionally, the detachable panel of the two-panel label on each blister card will be removed and affixed 
to the study medication Dispensing Log page at the time of dispensing.  Space is provided on both panels 
of the blister card label to record patient number, the visit week and dispensing date.   
5.2.3 
Unused Supplies 
At the end of the study, all unused investigational supplies must be inventoried on the Drug 
Accountability Log and returned to the sponsor or its representative, along with a completed and signed 
Drug Accountability Report/Material Shipping Form.  If any study medication is lost or damaged, it 
should be indicated on the form.

5.3 
Methods of Assigning Patients to Treatment Groups 
5.3.1 
Randomization 
Upon entry into the study (after ICF is signed at screening), all patients will be assigned a 
patient 
number.  
  
 
This 
 number is the main identifier for patients. 
Eligible patients will be randomized to receive either AVP-786-28/4.9, AVP-786-42.63/4.9, or placebo on 
Day 1 (Baseline) according to a randomization scheme devised by Avanir or its representative and 
managed within an IWRS.  The randomization will be stratified by the NPI Agitation/Aggression domain 
score (≤ 6 vs. > 6), risk assessment for falls (normal/mild vs. moderate/severe), and concomitant use of 
antipsychotic medications (yes vs. no).  Blocked randomization is used to ensure treatment balance in 
each stratum.  Patients will have at least a 
chance of receiving AVP 786 at some point during the 
study. 
5.3.2 
Blinding/Masking 
Blinding will be maintained by providing capsules of AVP-786 and placebo that are identical in 
appearance.  The sponsor, patients, caregivers, investigators, or other study personnel will not be aware of 
a patient’s treatment assignment.  In the event that it becomes medically necessary to identify which 
treatment a patient has received, the blind can be broken.  In that event, the investigator is to contact 
Avanir’s medical monitor or representative to request the unmasking of a patient.  The IWRS manager is 
not required to be blinded and he or she will have access to the study medication list and the 
randomization code. 
5.4 
Patient Compliance 
Patients and caregivers will be instructed to bring any unused study medication and empty containers to 
the clinic on Days 8, 15, 22, 43, 64, and 85 (Visits 2 – 6).  For this study, compliance will be defined as 
when a patient takes at least 80% of their scheduled doses (compliance range 80-120%).  Caregivers will 
be provided with diary cards and will be instructed to record daily the number of capsules taken and the 
time of administration.  Diary cards will be reviewed for compliance and collected on Days 22, 43, 64, 
and 85 (Visits 3 – 6), or at the time of early study discontinuation.  Patients should bring their Diary Card 
on Day 8 (Visit 2) and Day 15 (Visit 2.1) for compliance review; the Diary Card will be returned to the 
patient and collected at the next visit.  
5.5 
Concomitant Medications and Nondrug Therapies 
Patients may not take any of the disallowed medications listed in Appendix 1 during the study 
 
prior to the start of dosing on Day 1.  At each visit, caregivers will be 
queried as to whether or not the patient has taken any concomitant medications and, if so, the investigator 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 42 
 
will record the medications taken and the reasons for their use.  Caregivers will be instructed to record 
concomitant use of rescue medication 
 in the diary.  
  
 
 
  
 
 
 
 
 
 
. 
For patients who terminate early, the conditions of use for allowed concomitant medications and nondrug 
therapies or prohibited medications do not apply between the ET visit and the Follow-up visit.  Any use 
of medications during this period will be at the discretion of the investigator.  Patients should allow at 
least 14 days after stopping study medication before starting an MAOI.

5.5.2 
Rescue Medication for the Symptoms of Agitation 
Patients will be allowed to receive oral lorazepam as rescue medication for the short-term treatment of 
symptoms of agitation if deemed necessary by the investigator.  Lorazepam will be administered in a dose 
up to 1.5 mg/day and not to exceed 3 days in a 7-day period.  Caregivers must record concomitant use of 
lorazepam in the diary and must be reminded of the potential increase in the risk of falling by 
benzodiazepines.

5.5.4 
Nondrug Therapies 
Information on any prior and concomitant nondrug therapies will be recorded. 
5.5.5 
Nonpharmacological Interventions for the Treatment of Agitation 
Information on any nonpharmacological interventions for the treatment of agitation that were used prior 
to enrollment or used concomitantly during the study will be recorded.

STUDY ASSESSMENTS AND PROCEDURES 
6.1 
Efficacy 
Samples of all the scales and questionnaires to be used during the study are attached as Appendices.  
Whenever possible, each patient and caregiver should have the rating scales administered by the same 
raters throughout the study, for consistency of ratings.  The following scales MUST be administered by 
the same rater at each visit:  CMAI, NPI, mADCS-CGIC-Agitation, and CGIS-Agitation. 
6.1.1 
Cohen-Mansfield Agitation Inventory (CMAI) 
The CMAI will be used as the primary efficacy measure in this study.  The CMAI 
 is used to 
assess the frequency of manifestations of agitated behaviors in elderly persons.  
 
 
 
  
 
  
 
 
  Each of 
the 
 items is rated on a 7-point scale of frequency (1 = never, 2 = less than once a week but still 
occurring, 3 = once or twice a week, 4 = several times a week, 5 = once or twice a day, 6 = several times a 
day, 7 = several times an hour).  The ratings are based on the 2 weeks preceding assessment of CMAI.  
The CMAI (long-form version, 
 will be assessed at Screening (Day -28 to Day -1), Baseline 
(Day 1), Day 8 (Visit 2), Day 15 (Visit 2.1), Day 22 (Visit 3), Day 43 (Visit 4), Day 64 (Visit 5), and 
Day 85 (Visit 6), and Follow-up visit (for ET patients).  The CMAI must be administered by the same 
rater at each visit. 
6.1.2 
Neuropsychiatric Inventory (NPI) 
The NPI 
 is a validated clinical instrument for evaluating psychopathology in a variety of 
disease settings, including dementia.  The NPI is a retrospective caregiver-informant interview covering 
12 
neuropsychiatric 
symptom 
domains: 
delusions, 
hallucinations, 
agitation/aggression, 
depression/dysphoria, anxiety, elation/euphoria, apathy/indifference, disinhibition, irritability/lability, 
aberrant motor behavior, sleep and nighttime behavioral disorders, and appetite/eating disorders.  The 
scripted NPI interview includes a compound screening question for each symptom domain, followed by a 
list of interrogatives about domain-specific behaviors that is administered when a positive response to a 
screening question is elicited.  Neuropsychiatric manifestations within a domain are collectively rated by 
the caregiver in terms of both frequency (1 to 4) and severity (1 to 3), yielding a composite symptom 
domain score (frequency x severity).  Frequency and severity rating scales have defined anchor points to 
enhance the reliability of caregiver responses.  Caregiver distress is rated for each positive 
neuropsychiatric symptom domain on a scale anchored by scores of 0 (not distressing at all) to 
5 (extremely distressing).  The NPI will be administered to the patient’s caregiver at Baseline (Day 1), 
Day 22 (Visit 3), Day 43 (Visit 4), Day 64 (Visit 5), and Day 85 (Visit 6).  The Agitation/Aggression 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 45 
 
domain of the NPI will be administered to the patient’s caregiver at Screening (Day -28 to Day -1), Day 8 
(Visit 2), and Day 15 (Visit 2.1).  The NPI must be administered by the same rater at each visit. 
The NPI domains are generally evaluated for behaviors within the preceding 4 weeks but can be modified 
according to the needs of the study.  In this study, the recall period will be 2 weeks for all the visits.  
The NPI nursing-home version (NPI-NH) will be used for patients from in-patient or assisted living 
facilities.  The questions in the NPI-NH were rephrased for professional caregivers who may not know 
the patients prior to the onset of illness; however, the overall instrument domains and scoring is identical 
to the NPI except for the caregiver distress section which is replaced with occupational disruptiveness in 
the NPI-NH version.   
The Agitation/Aggression domain in the NPI will be assessed as part of the total NPI as described above 
and the composite score obtained for this category will be recorded separately at Baseline (Day 1), 
Day 22 (Visit 3), Day 43 (Visit 4), Day 64 (Visit 5), and Day 85 (Visit 6). 
6.1.3 
Clinical Global Impression of Severity of Illness-Agitation (CGIS-
Agitation) 
The CGIS 
 is an observer-rated scale that measures illness severity and is one of the most 
widely used brief assessment tools in psychiatry research.   
The Early Clinical Drug Evaluation Unit (ECDEU) version of the CGIS is the most widely used format of 
this validated tool, and asks that the clinician rate the patient relative to their past experience with other 
patients with the same diagnosis, with or without collateral information.  The CGIS has proved to be a 
robust measure of efficacy in many clinical drug trials22–26 and is easy and quick to administer, provided 
that the clinician knows the patient well.27  
Reliability and validity of CGI have been tested in multiple studies, including patients with dementia, 
schizophrenia and affective disorders.  Overall, CGI showed high correlation (r: ~90%) with other 
assessment instruments and it has also shown positive significant relationships and concurrent validity 
with other clinician’s rating.  In addition, the scale has good sensitivity to change over time.28–30  
The CGIS is a 7-point (1-7) scale (1 = normal, not at all ill; 7 = among the most extremely ill patients) 
and assesses severity of agitation in this study.  The CGIS-Agitation will be assessed at Screening (Day -
28 to Day -1), Baseline (Day 1), Day 43 (Visit 4), and Day 85 (Visit 6).  The CGIS-Agitation must be 
administered by the same rater at each visit. 
6.1.4 
Alzheimer’s Disease Cooperative Study - Clinical Global 
Impression of Change Rating (ADCS-CGIC-Overall) 
The intent of the ADCS version of the CGIC 
 (herein referred to as ADCS-CGIC-Overall), 
is to provide a means to reliably assess change from a baseline level of global function within the 
timeframe of a clinical trial.  Unlike a targeted symptom scale, the ADCS-CGIC-Overall takes into 
account a patient's overall function in the cognitive, behavioral and functional activity domains.  Relying 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 46 
 
on information gathered through a semi-structured interview of the patient and caregiver, the 
ADCS-CGIC-Overall focuses on clinician’s observations of change in the patient's cognitive, functional, 
and behavioral performance since the beginning of a trial.  Once the baseline level of severity is 
established, the change score at the follow-up visits is based on information gathered from the patient and 
caregiver interviews.  The ADCS-CGIC-Overall is rated as: marked improvement, moderate 
improvement, minimal improvement, no change, minimal worsening, moderate worsening, or marked 
worsening.   
The baseline ADCS-CGIC-Overall evaluation will be conducted at the Baseline (Day 1) visit.  The 
ADCS-CGIC-Overall will be assessed at Day 43 (Visit 4) and Day 85 (Visit 6) for change in Overall 
Clinical Status.  At Day 43 (Visit 4), change from the Baseline visit (Day 1) will be assessed.  At Day 85 
(Visit 6), change from Day 43 (Visit 4) and change from the Baseline visit (Day 1) will be assessed.  
6.1.5 
Modified Alzheimer’s Disease Cooperative Study - Clinical Global 
Impression of Change Rating (mADCS-CGIC-Agitation) 
The standard ADCS-CGIC instrument was modified to better assess aspects relevant to studying agitation 
in AD (mADCS-CGIC-Agitation).  The mADCS-CGIC-Agitation 
 contains questions 
related to agitation and an assessment of the Clinician’s Impression of Change focused specifically on 
agitation.  It was originally designed for the Citalopram study for Agitation in Alzheimer’s disease 
(CitAD)31,32 and utilizes a semi-structured interview of both patient and caregiver to determine a baseline 
level of severity for agitation.  Subsequent evaluations assess for change from baseline and also utilize the 
semi-structured agitation interview of both patient and caregiver.   
The baseline mADCS-CGIC-Agitation evaluation will be conducted at the Baseline (Day 1) visit.  The 
mADCS-CGIC-Agitation will be assessed at Day 43 (Visit 4), Day 85 (Visit 6) and Follow-up visit (for 
ET patients) for change in agitation syndrome.  At Day 43 (Visit 4), change from the Baseline visit (Day 
1) will be assessed.  At Day 85 (Visit 6), change from Day 43 (Visit 4) and change from the Baseline visit 
(Day 1) will be assessed.  At the Follow-up visit (for ET patients), change from Day 85 (Visit 6) will be 
assessed.  The mADCS-CGIC-Agitation must be administered by the same rater at each visit. 
6.1.6 
Zarit Burden Interview (ZBI) 
The ZBI 
 is a 22-item scale used to assess the impact of patient’s disabilities on the 
caregiver’s life.  It is designed to reflect the burden experienced by caregivers of dementia patients and 
can either be completed by the caregiver or administered as an interview.33 It is the most commonly used 
scale for measuring burden in caregivers’ of patients with dementia and also other illnesses.34  The ZBI 
has been shown to have high internal-reliability with an estimated Cronbach’s alpha at 0.88 and 0.91, and 
test-retest reliability at 0.71.  Validity has been estimated by correlating the total score with a single 
global rating of burden (r = 0.71).35  For each item of the scale, the caregiver has to indicate how often 
they felt that way (never, rarely, sometimes, quite frequently, or nearly always).  The score ranges from 
0 to 88 and is determined by adding the numbered responses of the individual items.  Higher scores 
indicate greater caregiver distress. 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 47 
 
The ZBI will be assessed at Baseline (Day 1), Day 43 (Visit 4), and Day 85 (Visit 6). 
6.1.7 
Patient Global Impression of Change (PGIC) 
The PGIC 
 is a 7-point (1-7) scale used to assess treatment response, and it is rated as: very 
much improved, much improved, minimally improved, no change, minimally worse, much worse, or very 
much worse.27  
The PGIC will be assessed and rated by the patient’s caregiver at Day 43 (Visit 4), and Day 85 (Visit 6), 
and will focus on the patient’s agitation.  
6.1.8 
Dementia Quality of Life (DEMQOL) 
The DEMQOL 
 is a scale used to evaluate health related quality of life in patients with 
dementia and their caregivers.36 There are 2 versions of the DEMQOL, a 28-item version (rated by 
patient) and a 31-item version (DEMQOL-proxy, rated by caregiver).  Both the 28-item and 31-item 
version are recommended to be used for evaluating patients (and their caregivers) with mild to moderate 
dementia (MMSE ≥10).  For patients with severe dementia, only the DEMQOL-proxy (administered to 
caregiver) is used.    
The DEMQOL-proxy (and DEMQOL for patients with MMSE ≥10 at the Baseline visit) will be assessed 
at Baseline (Day 1), Day 43 (Visit 4), and Day 85 (Visit 6). 
6.1.9 
Alzheimer’s 
Disease 
Assessment 
Scale-Cognitive 
Subscale 
(ADAS-cog) 
The ADAS 
 was designed to evaluate the cognitive and non-cognitive behavioral 
dysfunction characteristics of patients with AD.37  The cognitive sub-scale (ADAS-cog) consists of 
11 subsets related to memory, praxis, and language.  The ADAS-cog takes about 30 to 45 minutes to 
complete.     
The ADAS-cog will be assessed at Baseline (Day 1), Day 43 (Visit 4), and Day 85 (Visit 6) for patients 
with an MMSE score of ≥ 10 at the Baseline visit. 
6.1.10 
Cornell Scale for Depression in Dementia (CSDD) 
The CSDD 
 was specifically developed to assess signs and symptoms of major depression 
in patients with dementia.38  Because some of these patients may give unreliable reports, the CSDD uses a 
comprehensive interviewing approach that derives information from the patient and the caregiver.  
Information is elicited through two semi-structured interviews; an interview with a caregiver and an 
interview with the patient.  The interviews focus on depressive symptoms and signs occurring during the 
week preceding the assessment.  The CSDD takes approximately 20 minutes to administer.  
Each item is rated for severity on a scale of 0-2 (0 = absent, 1 = mild or intermittent, 2 = severe).  The 
item scores are added.  Scores above 10 indicate a probable major depression, scores above 18 indicate a 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 48 
 
definite major depression and scores below 6 as a rule are associated with absence of significant 
depressive symptoms. 
The CSDD will be assessed at Screening (Day -28 to Day -1), Day 43 (Visit 4), and Day 85 (Visit 6). 
6.1.11 
Resource Utilization in Dementia (RUD) 
The RUD 
 is used to calculate healthcare costs associated with dementia.39 It evaluates 
dementia patients’ utilization of formal and informal healthcare resources, including hospitalizations and 
doctor visits, living assistance, and time spent by nonprofessional caregivers.  Within the context of 
clinical trials, the RUD is often used to determine the cost effectiveness of new pharmaceutical 
treatments.40  
The RUD is administered as a semi-structured interview with the patient’s primary caregiver, and 
contains 2 sections; one focusing on caregiver impact (loss of work and leisure time incurred by 
caregiver) and the other focusing on the patient’s use of healthcare resources.  The total healthcare costs 
associated with the patient’s dementia can be estimated by multiplying the number of units used (e.g., 
hours of caregiver time, visits to doctors, nights in accommodation) by the corresponding unit price 
vector. 
The RUD will be assessed at Baseline (Day 1), Day 43 (Visit 4), and Day 85 (Visit 6). 
6.1.12 
General Medical Health Rating (GMHR) 
The GMHR 
 is a global clinical rating for medical health, designed to quantify in a single 
number (1 to 4) the severity of general co-morbidity in a patient with dementia.41  A rating of 1 = poor, 
2 = fair, 3 = good and 4 = excellent to very good.    
The GMHR will be assessed at Screening (Day -28 to Day -1) and Day 85 (Visit 6) 
6.2 
Pharmacokinetics (PK) 
At Day 43 (Visit 4) and Day 85 (Visit 6), patients will have a blood sample collected between 0 to 
3 hours after the morning dose of study medication for analysis of plasma levels of d6-DM, d6-DM 
metabolites and Q.  The time when the patient was administered the dose of study medication and the 
time of the blood draw will be recorded on the eCRF.  Plasma samples will be separated by centrifugation 
and then frozen at -20° C until assayed at the analytical unit.

6.3.1 
Adverse Events 
6.3.1.1 
Definitions 
An AE is any untoward medical occurrence or unintended change (including physical, psychological, or 
behavioral) from the time ICF is signed, including inter-current illness, which occurs during the course of 
a clinical trial after treatment has started, whether considered related to treatment or not.  An AE can 
therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for 
example), symptom, or disease temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product.  Changes associated with normal growth and development 
that do not vary in frequency or magnitude from that ordinarily anticipated clinically are not AEs (e.g., 
onset of menstruation occurring at a physiologically appropriate time). 
Clinical AEs should be described by diagnosis and not by symptoms when possible (e.g., cold, seasonal 
allergies, instead of “runny nose”). 
An overdose is a deliberate or inadvertent administration of a treatment at a dose higher than specified in 
the protocol and higher than known therapeutic doses.  It must be reported irrespective of outcome even if 
toxic effects were not observed. 
AEs will be graded on a 3-point scale and reported in detail as indicated on the eCRF: 
 
Mild:  
easily tolerated, causing minimal discomfort and not interfering with  
normal everyday activities 
 
Moderate:  
sufficiently discomforting to interfere with normal everyday activities 
 
Severe:  
incapacitating and/or preventing normal everyday activities 
The relationship of each AE to study medication should be determined by the investigator using the 
following explanations: 
 
Not related:  
the event is clearly related to other factors such as the patient’s clinical state, 
therapeutic interventions, or concomitant medications administered to the patient 
 
Unlikely related:  
the event is most likely produced by other factors such as the patient’s clinical 
state, therapeutic interventions, or concomitant medications administered to the 
patient; and does not follow a known response pattern to the study medication 
 
Possibly related:  
the event follows a reasonable temporal sequence from the time of drug 
administration; and/or follows a known response pattern to the study medication; 
but could have been produced by other factors such as the patient’s clinical state, 
therapeutic interventions, or concomitant medications administered to the patient 
 
Related:  
 the event follows a reasonable temporal sequence from the time of drug 
administration; and follows a known response pattern to the study medication;

and cannot be reasonably explained by other factors such as the patient’s clinical 
state, therapeutic interventions, or concomitant medications administered to the 
patient 
6.3.1.2 
Serious Adverse Events 
A Serious Adverse Event (SAE) is any AE occurring at any dose that results in any of the following 
outcomes: 
1. Death 
2. Life-threatening experience (one that places the patient, in the view of the initial reporter, at 
immediate risk of death from the AE as it occurred, i.e., it does not include an AE that, had it 
occurred in a more severe form, might have caused death) 
3. Persistent or significant disability/incapacity (disability is a substantial disruption of a person’s 
ability to conduct normal life functions) 
4. In-patient hospitalization or prolongation of hospitalization 
5. Congenital anomaly/birth defect 
Important medical events that may not result in death, or be life-threatening, or require hospitalization 
may be considered an SAE when, based upon appropriate medical judgment, they may jeopardize the 
patient or require medical or surgical intervention to prevent one of the outcomes listed in the definition. 
The terms “cancer” and “overdose” are not considered to be SAEs, but if a patient experiences cancer or 
overdose, they are still reportable as AEs. 
Pregnancy is not considered to be an AE or an SAE, unless a complication occurs that meets the 
requirements for an AE or SAE, but must be reported on a pregnancy report form.  Women who are 
pregnant or likely to become pregnant are excluded from this study.  In the event a patient becomes 
pregnant during the study, study medication must be discontinued, a pregnancy report form must be 
completed to capture potential drug exposure during pregnancy, and the pregnancy must be reported 
within 24 hours of notice.  Any pregnant patient must be followed until the outcome of her pregnancy is 
known (i.e., normal delivery, abnormal delivery, spontaneous/voluntary/therapeutic abortion).  The 
pregnancy (i.e., the mother and the fetus) must be followed up through delivery with regard to outcome.  
A pregnancy report form must also be completed in the event that a female partner of a male patient 
becomes pregnant within 30 days after his last dose of study medication or study completion, whichever 
is greater.  
The term ‘severe’ is a measure of intensity; thus a severe AE is not necessarily serious.  For example, 
nausea of several hours duration may be rated as severe, but may not be clinically serious.

Reporting 
Caregivers will be queried regarding AEs at each clinic visit after the screening visit (Baseline [Day 1], 
Days 8, 15, 22, 43, 64, 85 [Visit 2-6], Follow-up visit [for ET patients]), and at safety follow-up phone 
calls at Days 29 and 71.  The investigator will assess and record all reported AEs.  Any AE newly 
reported after receiving the last dose of study medication and up until 30 days after receiving the last dose 
of study medication will be followed. 
A death occurring during the study, or which comes to the attention of the investigator within 30 days 
after stopping the treatment whether considered treatment-related or not, must be reported to the sponsor. 
For all SAEs, including an abnormal laboratory test value, the investigator should consult with Avanir’s 
MM or designated representative as needed and report any SAE by fax/email form no later than 24 hours 
after becoming aware of the event.  Subsequently, the SAE must be assessed for the following details: 
seriousness of event, start date, stop date, intensity, frequency, relationship to test drug, action taken 
regarding test drug, treatment required, and outcome to date.  These details must be recorded on the 
clinical study AE form that is provided.  This form should be transmitted by fax and the details given by 
telephone to the contact numbers below. 
SAE reporting by FAX or e-mail correspondence  
FAX:  
 or 
 
E-mail
 
SAE hotline (24-hour/7 days a week) 
Phone: 
 or 
 
Such preliminary reports will be followed by detailed descriptions later, which may include copies of 
hospital case reports, autopsy reports, and other related documents when requested. 
The Institutional Review Board/Ethics Committee (IRB/EC) will be notified of such an event in writing 
as soon as is practical in compliance with federal and local regulations. 
6.3.1.4 
Procedures to be Followed in the Event of Abnormal Test Values 
Any patients with clinically significant abnormal laboratory test results may be required by the MM to 
have a repeat test 1 week later or earlier, if medically indicated.  Clinically significant laboratory 
abnormalities may be a basis for exclusion from study entry. 
6.3.2 
Physical and Neurological Examinations 
Physical and neurological examinations will be performed at Screening (Day -28 to Day -1), Day 43 
(Visit 4), and Day 85 (Visit 6).  The physical examination will include assessments of head, eyes, ears, 
nose, throat, lymph nodes, skin, extremities, respiratory, gastrointestinal, musculoskeletal, cardiovascular, 
and nervous systems.  The neurological examination will include assessments of mental status, cranial 
nerves, motor system, reflexes, coordination, gait and station, and sensory system.  The physical and 
neurological examinations should be performed by the same person each time, whenever possible.

Page 52 
 
Physical and neurological examination abnormalities determined by the investigator to be clinically 
significant at Screening should be recorded as medical history.  
Any clinically significant changes in physical and neurological examination findings from the screening 
examination should be recorded as AEs. 
6.3.3 
Vital Signs 
Orthostatic blood pressure (BP) and heart rate (HR) measurements will be performed at all clinic visits.  
Supine BP and HR will be measured after a patient has rested for at least 5 minutes in the supine position.  
Each measurement will be taken twice in the same position and recorded.  After the measurement of 
supine BP and HR, the patient will stand still for up to 3 minutes and a single measurement of standing 
BP and HR will be recorded within these 3 minutes of standing.  
Respiratory rate (breaths/minute) and body temperature (ºF) will be assessed at all clinic visits.  Weight 
will be recorded at Baseline (Day 1) and Day 85 (Visit 6).  
6.3.4 
Clinical Laboratory Tests 
The following clinical laboratory assessments are to be performed at Screening (Day -28 to Day -1), 
Day 22 (Visit 3), Day 43 (Visit 4), Day 64 (Visit 5), and Day 85 (Visit 6): 
• 
Blood chemistry (calcium, magnesium, phosphorus, glucose, sodium, potassium, chloride, 
carbon dioxide, blood urea nitrogen [BUN], serum creatinine, uric acid, albumin, total bilirubin, 
alkaline phosphatase, lactate dehydrogenase [LDH], aspartate aminotransferase/serum glutamic 
oxaloacetic transaminase [AST/SGOT], alanine aminotransferase/serum glutamic pyruvic 
transaminase [ALT/SGPT], creatine kinase [CK], gamma-glutamyl transferase [GGT], 
triglycerides, total protein, and total cholesterol) 
• 
Hematology (red blood cell [RBC] count, hemoglobin, hematocrit, white blood cell [WBC] 
count, neutrophils, bands, lymphocytes, monocytes, eosinophils, basophils, platelet count, and 
morphology) 
• 
Urinalysis (pH, specific gravity, protein, glucose, ketones, blood, leucocyte esterase, nitrates, 
and microscopic appearance) 
• 
Thyroid function tests (TSH, and reflex T3 and T4 if TSH is abnormal) at Screening visit only 
• 
Glycosylated hemoglobin (HbA1c) test at the Screening visit and Visit 6 only 
Any patients with clinically significant abnormal laboratory test results may be required by the MM to 
have a repeat test 1 week later or earlier, if medically indicated.  Clinically significant laboratory 
abnormalities may be a basis for exclusion from study entry.

6.3.5 
Pregnancy Tests 
Urine pregnancy tests are to be performed for females of childbearing potential at Screening (Day -28 to 
Day -1), Baseline (Day 1), Day 43 (Visit 4), and Day 85 (Visit 6). 
All female patients of childbearing potential should be instructed to use appropriate birth control methods 
for up to 4 weeks following the last dose of study medication.  
6.3.6 
Electrocardiograms 
A resting 12-lead ECG will be performed at all clinic visits except on Day 8 (Visit 2).  At Screening, ECG 
will be performed in triplicate.  At Baseline (Day 1), two ECGs will be performed; one prior to study 
medication dosing and one 2-3 hours after dosing.  ECG equipment will be provided by the central reader.  
ECG data will be recorded at the study center and will include general findings, heart rate (beats/minute) 
QRS complex and PR and QTc intervals (milliseconds).  Results will be provided by the central reader to 
the investigators within 24 hours.  ECG data will be transferred automatically from the central reader into 
the eCRF monthly.  ECG abnormalities present at Screening will be recorded as medical history.  Any 
changes from the ECG status at Screening Visit that are deemed to be clinically significant by the 
investigator should be captured as AEs.  Any clinically significant abnormal ECG should be discussed 
with the study MM and, if necessary be repeated within a 1-week period. 
6.3.7 
Sheehan Suicidality Tracking Scale (S-STS) 
The S-STS 
 is a prospective scale that assesses treatment-emergent suicidal thoughts and 
behaviors.42  Each item of the S-STS is scored on a 5-point Likert scale (0 = not at all; 1 = a little; 
2 = moderate; 3 = very; and 4 = extremely).  The Sheehan-STS can be analyzed as individual item scores, 
suicidal ideation subscale score, suicidal behavior subscale score, or total score.  For the screening visit, 
the timeframe for the items on the scale will be ‘in the past 6 months’ and for all other visits it will be 
‘since last visit’.      
The S-STS will be assessed at Screening (Day -28 to Day -1), Baseline (Day 1), Day 8 (Visit 2), Day 15 
(Visit 2.1), Day 22 (Visit 3), Day 43 (Visit 4), Day 64 (Visit 5), Day 85 (Visit 6), and Follow-up visit (for 
ET patients).  Any change in the S-STS score indicating the presence of suicidality should be evaluated 
by the investigator and reported to the MM. 
6.3.8 
Mini Mental State Examination (MMSE) 
The MMSE 
 is a brief 30-point questionnaire test that is used to screen for cognitive 
impairment.  It is commonly used in medicine to screen for dementia.  It is also used to estimate the 
severity of cognitive impairment at a specific time and to follow the course of cognitive changes in an 
individual over time, thus making it an effective way to document an individual’s response to treatment.  
The MMSE scale comprises 11 questions or simple tasks concerning orientation, memory, attention, and 
language to evaluate the patient’s cognitive state.43  It requires only 5 to 10 minutes for a trained rater to 
administer it. 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302

The MMSE will be assessed at Screening (Day -28 to Day -1), Baseline (Day 1), Day 43 (Visit 4), and 
Day 85 (Visit 6). 
6.3.9 
Timed Up and Go (TUG) Test 
The TUG test 
 measures the time (in seconds) taken for an individual to stand up from a 
standard armchair, walk 3 meters, turn, walk back to the chair and sit down.  It is a commonly used scale 
for measuring functional mobility and risk of falls.44,45  
The TUG test will be performed at Screening (Day -28 to Day -1), Day 43 (Visit 4), and Day 85 (Visit 6).  
6.3.10 
Epworth Sleepiness Scale (ESS) 
The ESS 
 is an 8-item questionnaire that is used to measure sleepiness by rating the 
probability of falling asleep on 8 different situations that most people engage in during the day.46  The 
questions are rated on a 4 point scale (0 to 3) where 0 = would never doze, 1 = slight chance of dozing, 
2 = moderate chance of dozing, and 3 = high chance of dozing.  A total score of 0 to 9 is considered to be 
normal.    
The ESS will be assessed at Baseline (Day 1), Day 43 (Visit 4), and Day 85 (Visit 6) for patients with an 
MMSE score of ≥ 10 at the Baseline visit. 
6.4 
Schedule of Evaluations and Procedures 
A schedule of evaluations and procedures is provided in Table 1. 
6.4.1

DATA MANAGEMENT 
7.1 
Data Collection 
The sponsor or designated representative (e.g., CRO) will perform the data management activities in 
accordance with the data management plan (DMP).  The DMP will outline the systems and procedures to 
be used in the study. 
Clinical study data will be reported (captured) by study site personnel on eCRFs.  An eCRF must be 
completed for every patient enrolled in the study.  The eCRF data will be entered by trained study-site 
personnel and then reviewed for completeness and accuracy and electronically signed by the investigator 
or authorized designee.  All study-site personnel must use a password-protected user account to enter, 
review, or correct study data.  Electronic signature procedures shall comply with the CFR Title 21 
Part 11.  Passwords will be strictly confidential. 
All eCRF data will be exported from the electronic data capture (EDC) system and transferred to the 
sponsor or representative.  The sponsor or representative will also receive electronic transfers of non-
eCRF data such as laboratory data from the central laboratory, ECG data from the central ECG reader, as 
well as other data from third-party vendors as appropriate.  The electronic data format of all transfers will 
be agreed upon with the sponsor or representative and documented in the DMP or vendor data transfer 
requirements document as appropriate. 
The clinical monitoring staff will perform source data verification (SDV) of the data recorded in the EDC 
system with source documents at the clinical study sites according to the data management plan and 
clinical monitoring plan.  The data will be subjected to consistency and validation checks within the EDC 
system with supplemental data reviews performed outside of the EDC system.   
Medical history and adverse events will be coded using a current version of Medical Dictionary for 
Regulatory Activities (MedDRA), and concomitant medications using a current version of the WHO Drug 
Dictionary.  The sponsor or representative will perform a medical safety review of the coding. 
Completed eCRF images with a date- and time-stamped electronic audit trail indicating the user, the data 
entered, and any reason for change (if applicable) will be archived at the investigator’s site and at the 
sponsor’s site.

STATISTICAL METHODS 
8.1 
Analysis Populations 
Three analysis populations will be used; modified intent-to-treat (mITT), intent-to-treat (ITT), and safety. 
• 
mITT:  The mITT population includes all patients randomized in the study who had at least one 
post-baseline efficacy assessment.  The mITT population will be used for all analyses of efficacy.  
Patients will be included in the treatment group to which they were randomized regardless of 
treatment received.  
• 
ITT:  The ITT population includes all randomized patients in the study.  The ITT population will 
be used for exploratory efficacy analyses. 
• 
Safety:  The safety population includes all patients who received study treatment.  The safety 
population will be used for all analyses of safety.  Patients will be included in the treatment group 
based on the actual treatment received. 
8.2 
Demographic and Baseline Characteristics 
Demographic and baseline characteristics will be summarized by treatment group for the ITT and mITT 
populations using descriptive statistics.  
8.3 
Efficacy Analysis 
8.3.1 
Study Endpoints 
Primary efficacy endpoint: 
The primary efficacy endpoint is the change from Baseline to Week 12 (Day 85) in the composite CMAI 
scores.  
Secondary efficacy endpoints: 
The secondary efficacy endpoints are the change from Baseline to Week 12 (Day 85) in the following 
measures:   
• mADCS-CGIC-Agitation  
• NPI-Agitation/Aggression domain score and Caregiver Distress score 
• NPI-Aberrant Motor Behavior domain 
• ZBI 
• NPI-Irritability/Lability domain 
• Total NPI

8.3.2 
Primary Efficacy Analysis 
The primary efficacy endpoint is the change from baseline to Day 85 (Week 12) in the composite CMAI 
scores.     
For the primary efficacy analysis, the null hypothesis is that there is no treatment effect between AVP-
786-42.63/4.9 and placebo during the study and it will be tested against the alternative that there is a 
treatment effect. Similar hypotheses apply to the comparison of the AVP-786-28/4.9 vs. placebo. The 
treatment effect will be estimated by using a linear mixed effects model repeated measures (MMRM) 
with comparisons being made between the patients treated with AVP-786 and the patients treated with 
concurrent placebo.  The model will include fixed effects for treatment, visit, treatment-by-visit 
interaction, baseline-by-visit interaction, and baseline covariates which include baseline value and other 
factors as appropriate.  An unstructured covariance model will be used.   
Analyses with missing values imputed by last observation carried forward (LOCF) and Multiple 
Imputation (MI) may be performed as sensitivity analyses.   
A gate-keeping procedure will be used to control the overall type I error at 2-sided α = 0.05 for the 2 
primary treatment comparisons (AVP-786-42.63/4.9 vs. placebo and AVP-786-28/4.9 vs. placebo). 
Specifically, the comparison between AVP-786-42.63/4.9 vs. placebo will be performed first at the 
significance level of 0.05.  If the comparison is statistically significant, the comparison between 
AVP-786-28/4.9 vs. placebo will be performed at the same significance level. 
8.3.3 
Secondary Efficacy Analyses 
Secondary efficacy endpoints include change from Baseline to Week 12 (Day 85) for the following 
efficacy measures: mADCS-CGIC-Agitation, NPI-Agitation/Aggression domain score and Caregiver 
Distress score, NPI-Aberrant Motor Behavior domain score, ZBI, NPI- Irritability/Lability domain score, 
PGIC, DEMQOL, CSDD, RUD, total NPI, CGIS-Agitation, ADCS-CGIC-Overall, ADAS-cog, and 
GMHR.

Page 69 
 
Treatment comparison tests using similar MMRM method as the primary efficacy analysis will be 
performed when appropriate.  A proper multiple comparison procedure, e.g, gate keeping procedure, will 
be used to control overall type I error at 2-sided α = 0.05 for the secondary endpoints tested.  The testing 
procedure will be pre-specified in the statistical analysis plan (SAP) before un-blinding the study.   
8.4 
PK/PD Analysis 
Plasma concentrations of d6-DM, its metabolites, and Q will be measured and results will be summarized 
descriptively 
.  Plasma 
concentration results will be used to assess the PK properties of d6-DM and its metabolites.  Additional 
PK/PD correlations may also be performed.  Additional details will be described in the SAP. 
8.6 
Safety Analysis 
Safety will be assessed by the following measurements:  AEs, physical and neurological examination, 
vital signs, urine pregnancy test, clinical laboratory assessments, resting 12-lead ECG, S-STS, MMSE, 
TUG test, and ESS.   
Safety analyses will consist of data summaries for biological parameters and AEs.  Safety analyses will be 
tabulated by treatment.   
8.6.1 
Adverse Events 
AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA).  The percentages 
of patients experiencing 1 or more AEs will be summarized by treatment, system organ class (SOC), 
deaths, non-fatal SAEs, AEs, AEs resulting in study discontinuation, and treatment-emergent AEs 
(TEAE).  TEAEs are those AEs that occur after the first dose of study medication up until 30 days after 
last dose.   
8.6.2 
Vital Signs and ECGs  
Summary statistics of absolute values and percentage change from baseline for BP (diastolic and 
systolic), heart rate, respiratory rate, and ECG parameters will be provided.  All values outside a pre-
defined normal range will be highlighted in the individual patient data listings. 
8.6.3 
Clinical Laboratory Values 
Laboratory parameters will be summarized via descriptive statistics and via shifts in results in respect to 
normal ranges between Screening and end of treatment as increased, decreased, or no change.

8.6.4 
Data and Safety Monitoring Board 
The sponsor will appoint a Data and Safety Monitoring Board (DSMB) for the periodic review of 
available study data. 
The DSMB is an independent group of experts that advises the sponsor and the study investigators.  The 
members of the DSMB serve in an individual capacity and provide their expertise and recommendations.  
The primary responsibilities of the DSMB are to (1) periodically review and evaluate the accumulated 
study data for participant safety, study conduct and progress, and (2) make recommendations to the 
sponsor concerning the continuation, modification, or termination of the study.  
The DSMB considers study-specific data as well as relevant background knowledge about the disease, 
test agent, or patient population under study.  
The DSMB is responsible for defining its deliberative processes, including event triggers that would call 
for an unscheduled review, stopping guidelines, unmasking, and voting procedures prior to initiating any 
data review.  The DSMB is also responsible for maintaining the confidentiality of its internal discussions 
and activities as well as the contents of reports provided to it. 
8.6.5 
Interim Analysis 
Interim analysis may be performed and will be prespecified in the SAP. 
8.7 
Sample Size Calculations  
Power calculation was performed assuming a normal distribution for the primary efficacy endpoint.  
 
 
 
  
 
  
The study protocol is amended to include another dose arm (AVP-786-42.63/4.9) with 140 patients in the 
treatment arm, when approximately 100 patients have already been enrolled (50 AVP-786 28/4.9 and 50 
placebo) in the study.  To maintain an approximate 
 chance for an incoming patient to receive active 
drug, the sample size for the placebo treatment group is amended to 190.  Overall, the total sample size of 
470 patients will include 140 patients for AVP-786 28/4.9 and AVP-786 42.63/4.9 groups each and 190 
patients in the placebo group.  This sample size will provide approximately 
 power to detect a 
treatment effect size of 
between AVP-786 42.63/4.9 and concurrent placebo treatment group.

ADMINISTRATIVE PROCEDURES 
9.1 
Institutional Review Board/Ethics Committee Approval 
Institutional Review Boards/Ethics Committees (IRBs/ECs) must meet the guidelines set out by the FDA 
and conform to local laws and customs where appropriate.  Written IRB/EC approval for the protocol and 
the signed ICF must be obtained and transmitted to Avanir Pharmaceuticals or representative before the 
study can be initiated.  The IRB/EC must be informed of and approve all protocol amendments.  The 
investigator will ensure that this study is conducted in full conformance with local laws and according to 
National and State/Provincial laws (see, Appendix 18, Investigator Responsibilities).  The complete text 
of the World Medical Association Declaration of Helsinki is given in Appendix 19. 
9.2 
Informed Consent Form 
The ICF will follow the principles outlined in the current version of the Declaration of Helsinki.  For each 
patient found to be eligible for the study, informed consent will be obtained from the patient (if the patient 
is capable in the judgment of the investigator to provide informed consent) or the authorized 
representative.  For patients that are not capable of providing informed consent, but are capable of 
providing assent, the patient will be asked to provide assent.  If the patient is not capable of providing 
assent, the investigator will document the reasons why and maintain that documentation with the other 
informed consent documents.  The patient’s caregiver will also be asked to provide informed consent as 
they will be providing data on themselves and the patient, as well as, being responsible for ensuring 
compliance from the patient between study visits. 
The patients and/or patient’s authorized representative and the caregiver will be properly informed of the 
purpose of the study.  The patients and/or patient’s authorized representative and the caregiver will be 
alerted to any anticipated AE that may be encountered with the study medication.  A signed ICF will be 
obtained from all patients and/or patient’s authorized representative and the caregiver prior to patient 
entry into this study.  Patients and/or patient’s authorized representative and the caregiver will be 
provided with a copy of their signed and dated ICF. 
9.3 
Patient’s Diary Card 
The Patient’s Diary Card will be reviewed by clinical study personnel at all study treatment visits for 
confirmation of medication dosage and any rescue medication received.  The study personnel are 
responsible for (i) ensuring that patients and/or caregivers are properly collecting data and recording it 
into the diaries; and (ii) transcribing the diary recordings into the eCRF.  The diary will be collected at all 
study visits after baseline except Visit 2 (Day 8) and Visit 2.1 (Day 15), wherein the diary will be 
reviewed and returned to the patient.  The originals of all diaries will be maintained at the site as source 
documents.

Version 5.0  
 
 
Page 72 
 
9.4 
Electronic Case Report Forms 
For each patient enrolled who has given informed consent, an eCRF must be completed and electronically 
signed by the investigator to certify that the data within each eCRF are complete and correct.  This also 
applies to those patients who fail to complete the study.  If a patient is withdrawn from the study because 
of a treatment-limiting AE, thorough efforts should be made to document the outcome.  
Any site personnel delegated responsibility for data entry, query resolution, or eCRF approval must 
complete training prior to accessing the eCRF.  The electronic data capture (EDC) vendor will provide 
user-specific access to the live (production) eCRF once training completion has been confirmed and the 
account has been approved by the sponsor.  Changes to the data once it has been initially saved will be 
tracked via audit trail and will require a reason for the change.  The audit trail will also include who made 
the change and a date/time stamp. 
The eCRFs will be reviewed by the study monitor at the study site.  Errors detected by subsequent in-
house data review may necessitate clarification or correction of errors.  All changes will be documented 
and approved by the investigator. 
All investigators will be provided with copies of the eCRFs for their site on a CD-ROM at the end of the 
study. 
9.5 
Quality Assurance 
9.5.1 
Documentation 
For each process, evaluation, or test that generates study data but is not described in the protocol or eCRF, 
a written description of the data generation procedures shall be retained in the quality assurance section of 
the study files.  In the case of routine clinical diagnostic procedures, only a copy of the relevant 
certification document is required. 
9.5.2 
Monitoring 
Throughout the course of the study, the study monitor will make frequent contacts with the investigator.  
This will include telephone calls and on-site visits.  The study will be routinely monitored to ensure 
compliance with the study protocol and the overall quality of data collected.  During the on-site visits, the 
eCRFs will be reviewed for completeness and adherence to the protocol.  As part of the data audit, source 
documents will be made available for review by the study monitor.  The study monitor may periodically 
request review of the investigator study file to assure the completeness of documentation in all respects of 
clinical study conduct. 
The study monitor will verify that each patient has proper consent documentation from the patient and/or 
patient’s authorized representative and the caregiver for study procedures and for the release of medical 
records to the sponsor, FDA, other regulatory authorities, and the IRB/EC.  The study monitor will also 
verify that assent was obtained for patients not capable of providing informed consent or that 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 73 
 
documentation is provided by the investigator explaining why the patient was unable to provide assent.  
The investigator or appointed delegate will receive the study monitor during these on-site visits and will 
cooperate in providing the documents for inspection and respond to inquiries.  In addition, the 
investigator will permit inspection of the study files by authorized representatives of the regulatory 
agencies. 
On completion of the study, the study monitor will arrange for a final review of the study files after which 
the files should be secured for the appropriate time period. 
9.6 
Record Retention 
To enable evaluations and/or audits from regulatory authorities or Avanir, the investigator agrees to keep 
records, including the identity of all participating patients (sufficient information to link records, e.g., 
CRFs and hospital records), all original signed ICFs, copies of all eCRFs, SAE forms, source documents, 
and detailed records of treatment disposition, and adequate documentation of relevant correspondence 
(e.g., letters, meeting minutes, telephone call reports).  The records should be retained by the investigator 
according to ICH, local regulations, or as specified in the Clinical Trial Agreement, whichever is longer. 
If the investigator is unable for any reason to continue to retain study records for the required period (e.g., 
retirement, relocation), Avanir should be prospectively notified.  The study records must be transferred to 
a designee acceptable by Avanir, such as another investigator, another institution, or to Avanir.  The 
investigator must obtain Avanir’s written permission before disposing of any records, even if retention 
requirements have been met. 
9.7 
Source Data 
The documents that will form the source data for the clinical study (e.g., patient charts, laboratory reports) 
must be defined and documented in the in-house study master file prior to the start of the study.  Data on 
the eCRFs which will be checked against source data during monitoring visits must also be defined and 
documented in the in-house study master file including the percentage of each of the source data to be 
verified and the percentage of patients’ eCRFs to be monitored. 
9.8 
Data Handling 
Data collected on the eCRFs will be entered into EDC system by trained site staff.  Any queries arising 
from data entry will be checked with the investigator and changes approved.  
9.9 
Laboratory Procedures 
Each individual site laboratory will collect hematology and chemistry blood samples and urine samples at 
Screening (Day -28 to Day -1), and Visits 3-6 (Day 22, Day 43, Day 64, and Day 85) for safety analysis.  
Instructions for specimen evaluation and transport to a central laboratory will be provided at the time of 
study initiation.  Blood samples will also be taken 
 for 

 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-302 
Version 5.0  
 
 
Page 74 
 
PK analysis on Visits 4 and 6 (Day 43 and Day 85).  Instructions for shipping the laboratory samples for 
evaluation by central facilities will be provided. 
9.10 
Guidelines for Good Clinical Practice 
Standards for GCP must be adhered to for all study-based procedures. 
9.11 
Conditions for Amending the Protocol 
Protocol modification to ongoing studies which could potentially adversely affect the safety of patients or 
which alter the scope of the investigation, the scientific quality of the study, the experimental design, 
dosages, duration of therapy, assessment variables, the number of patients treated, or patient selection 
criteria must be made only after appropriate consultation between an appropriate representative of Avanir 
and the investigator. 
Protocol modifications must be prepared by a representative of Avanir or the investigator, and reviewed 
and approved by Avanir.   
All protocol modifications must be reviewed and approved by the appropriate IRB/EC in accordance with 
local requirements, before the revised edition can be implemented.  Modifications which eliminate an 
apparent immediate hazard to patients do not require pre-approval by the IRB/EC. 
9.12 
Conditions for Terminating the Study 
Both Avanir and the principal investigator reserve the right to terminate the study at the site at any time.  
Should this be necessary, the procedures to effect study termination will be arranged after review and 
consultation by both parties.  In terminating the study, Avanir and the investigator will assure that 
adequate consideration is given to the protection of the patient’s interests. 
9.13 
Confidentiality of Study Documents and Patient Records 
The investigator must assure that the patient’s anonymity will be maintained.  On eCRFs or other 
documents submitted to Avanir, patients should not be identified by their names but by an identification 
code. 
The investigator should keep a separate log of patient’s codes, names, and addresses.  Documents not for 
submission to Avanir, for example, patients’ signed ICFs, should be maintained by the investigator in 
strict confidence. 
9.14 
Reports 
At the completion of the study, the investigator shall provide the sponsor with an adequate report shortly 
after completion of the investigator's participation in the study as described in the Code of Federal 
Regulations (CFR) Title 21, Part 312.64.

9.15 
Publications 
It is anticipated that a report of this study will be published in the scientific literature by the sponsor.  The 
investigator will not seek to arrange for publication of any of the information or results from the study in 
any scientific journal, or other publication or by way of lecture without Avanir’s prior review and written 
consent.  
9.16 
Audits/Inspections 
The investigator should understand that source documents for this study should be made available to 
appropriately qualified personnel or designee(s) from Avanir or to health authority inspectors after 
appropriate notification.  The verification of the eCRF data may be by direct inspection of source 
documents (where permitted by law) or through an interview exchange. 
The inspector from the regulatory authority will be especially interested in the following items: 
• 
Visits from the sponsor’s representatives 
• 
IRB/EC approval(s) 
• 
Study medication accountability 
• 
Study protocol and amendments 
• 
ICFs of the patient (if capable of providing ICF, according to the investigator) or patient’s 
authorized representatives and caregivers 
• 
Assent of the patients (if capable of providing assent, according to the investigator) 
• 
Medical records supportive of eCRF data 
• 
Reports to the IRB/EC and the sponsor 
• 
Record retention 
The sponsor will be available to help investigators prepare for an inspection.

4.2.4  The investigator should ensure that all persons assisting with the trial are
adequately informed about the protocol, the investigational product(s), and their
trial-related duties and functions.
4.3
Medical Care of Trial Subjects
4.3.1  A qualified physician (or dentist, when appropriate), who is an investigator
or a subinvestigator for the trial, should be responsible for all trial-related medical
(or dental) decisions. 
4.3.2  During and following a subject's participation in a  trial, the
investigator/institution should ensure that adequate medical care is provided to a
subject for any adverse events, including clinically significant laboratory values,
related to the trial. The investigator/institution should inform a subject when
medical care is needed for intercurrent illness(es) of which the investigator
becomes aware. 
4.3.3  It is recommended that the investigator inform the subject's primary
physician about the subject's participation in the trial if the subject has a primary
physician and if the subject agrees to the primary physician being informed.

15
4.3.4  Although a subject is not obliged to give his/her reason(s) for withdrawing
prematurely from a trial, the investigator should make a reasonable effort to
ascertain the reason(s), while fully respecting the subject's rights.
4.4
Communication with IRB/IEC
4.4.1  Before initiating a trial, the investigator/institution should have written and
dated approval/favorable opinion from the IRB/IEC for the trial protocol, written
informed consent form, consent form updates, subject recruitment procedures
(e.g., advertisements), and any other written information to be provided to
subjects. 
4.4.2  As part of the investigator's/institution’s written application to the IRB/IEC,
the investigator/institution should provide the IRB/IEC with a current copy of the
Investigator's Brochure.  If the Investigator's Brochure is updated during the trial,
the investigator/institution should supply a copy of the updated Investigator’s
Brochure to the IRB/IEC.
4.4.3  During the trial the investigator/institution should provide to the IRB/IEC all
documents subject to its review.  
4.5
Compliance with Protocol
4.5.1  The investigator/institution should conduct the trial in compliance with the
protocol agreed to by the sponsor and, if required, by the regulatory authority(ies),
and which was given approval/favorable opinion by the IRB/IEC.  The
investigator/institution and the sponsor should sign the protocol, or an alternative
contract, to confirm their agreement.
4.5.2  The investigator should not implement any deviation from, or changes of,
the protocol without agreement by the sponsor and prior review and documented
approval/favorable opinion from the IRB/IEC of an amendment, except where
necessary to eliminate an immediate hazard(s) to trial subjects, or when the
change(s)  involves only logistical or administrative aspects of the trial (e.g.,
change of monitor(s), change of telephone number(s)).
4.5.3  The investigator, or person designated by the investigator, should document
and explain any deviation from the approved protocol.
4.5.4  The investigator may implement a deviation from, or a change in, the
protocol to eliminate an immediate hazard(s) to trial subjects without prior
IRB/IEC approval/favorable opinion.  As soon as possible, the implemented

16
 deviation or change, the reasons for it, and, if appropriate, the proposed protocol
amendment(s) should be submitted:
(a)  To the IRB/IEC for review and approval/favorable opinion;
(b)  To the sponsor for agreement and, if required; 
(c)  To the regulatory authority(ies).
4.6
Investigational Product(s)
4.6.1  Responsibility for investigational product(s) accountability at the trial site(s)
rests with the investigator/institution.
4.6.2  Where allowed/required, the investigator/institution may/should assign some
or all of the investigator's/institution’s duties for investigational product(s)
accountability at the trial site(s) to an appropriate pharmacist or another
appropriate individual who is under the supervision of the investigator/institution.
4.6.3  The investigator/institution and/or a pharmacist or other appropriate
individual, who is designated by the investigator/institution, should maintain
records of the product's delivery to the trial site, the inventory at the site, the use
by each subject, and the return to the sponsor or alternative disposition of unused
product(s).  These records should include dates, quantities, batch/serial numbers,
expiration dates (if applicable), and the unique code numbers assigned to the
investigational product(s) and trial subjects. Investigators should maintain records
that document adequately that the subjects were provided the doses specified by
the protocol and reconcile all investigational product(s) received from the sponsor.
4.6.4  The investigational product(s) should be stored as specified by the sponsor
(see sections 5.13.2 and 5.14.3) and in accordance with applicable regulatory
requirement(s).
4.6.5  The investigator should ensure that the investigational product(s) are used
only in accordance with the approved protocol.
4.6.6  The investigator, or a person designated by the investigator/institution,
should explain the correct use of the investigational product(s) to each subject and
should check, at intervals appropriate for the trial, that each subject is following
the instructions properly.
4.7
Randomization Procedures and Unblinding
The investigator should follow the trial's randomization procedures, if any, and should
ensure that the code is broken only in accordance with the protocol.  If the trial is blinded,

17
the investigator should promptly document and explain to the sponsor any premature
unblinding (e.g., accidental unblinding, unblinding due to a serious adverse event) of the
investigational product(s).
4.8
Informed Consent of Trial Subjects
4.8.1  In obtaining and documenting informed consent, the investigator should
comply with the applicable regulatory requirement(s), and should adhere to GCP
and to the ethical principles that have their origin in the Declaration of Helsinki. 
Prior to the beginning of the trial, the investigator should have the IRB/IEC's
written approval/favorable opinion of the written informed consent form and any
other written information to be provided to subjects.
4.8.2  The written informed consent form and any other written information to be
provided to subjects should be revised whenever important new information
becomes available that may be relevant to the subject’s consent.  Any revised
written informed consent form, and written information should receive the
IRB/IEC's approval/favorable opinion in advance of use.  The subject or the
subject’s legally acceptable representative should be informed in a timely manner if
new information becomes available that may be relevant to the subject’s
willingness to continue participation in the trial.  The communication of this
information should be documented.
4.8.3  Neither the investigator, nor the trial staff, should coerce or unduly influence
a subject to participate or to continue to participate in a trial.
4.8.4  None of the oral and written information concerning the trial, including the
written informed consent form, should contain any language that causes the subject
or the subject's legally acceptable representative to waive or to appear to waive
any legal rights, or that releases or appears to release the investigator, the
institution, the sponsor, or their agents from liability for negligence.
4.8.5  The investigator, or a person designated by the investigator, should fully
inform the subject or, if the subject is unable to provide informed consent, the
subject's legally acceptable representative, of all pertinent aspects of the trial
including the written information given approval/favorable opinion by the
IRB/IEC.
4.8.6  The language used in the oral and written information about the trial,
including the written informed consent form, should be as nontechnical as practical
and should be understandable to the subject or the subject's legally acceptable
representative and the impartial witness, where applicable. 

18
4.8.7  Before informed consent may be obtained, the investigator, or a person
designated by the investigator, should provide the subject or the subject's legally
acceptable representative ample time and opportunity to inquire about details of
the trial and to decide whether or not to participate in the trial.  All questions
about the trial should be answered to the satisfaction of the subject or the subject's
legally acceptable representative.
4.8.8  Prior to a subject’s participation in the trial, the written informed consent
form should be signed and personally dated by the subject or by the subject's
legally acceptable representative, and by the person who conducted the informed
consent discussion. 
4.8.9  If a subject is unable to read or if a legally acceptable representative is
unable to read, an impartial witness should be present during the entire informed
consent discussion.  After the written informed consent form and any other written
information to be provided to subjects is read and explained to the subject or the
subject’s legally acceptable representative, and after the subject or the subject’s
legally acceptable representative has orally consented to the subject’s participation
in the trial, and, if capable of doing so, has signed and personally dated the
informed consent form, the witness should sign and personally date the consent
form.  By signing the consent form, the witness attests that the information in the
consent form and any other written information was accurately explained to, and
apparently understood by, the subject or the subject's legally acceptable
representative, and that informed consent was freely given by the subject or the
subject’s legally acceptable representative.
4.8.10  Both the informed consent discussion and the written informed consent
form and any other written information to be provided to subjects should include
explanations of the following:
(a)  That the trial involves research.
(b)  The purpose of the trial.
(c)  The trial treatment(s) and the probability for random assignment to
each treatment.
(d)  The trial procedures to be followed, including all invasive procedures.
(e)  The subject's responsibilities.
(f)  Those aspects of the trial that are experimental.

19
(g)  The reasonably foreseeable risks or inconveniences to the subject and,
when applicable, to an embryo, fetus, or nursing infant.
(h)  The reasonably expected benefits.  When there is no intended clinical
benefit to the subject, the subject should be made aware of this. 
(i)  The alternative procedure(s) or course(s) of treatment that may be
available to the subject, and their important potential benefits and risks. 
(j)  The compensation and/or treatment available to the subject in the event
of trial-related injury. 
(k)  The anticipated prorated payment, if any, to the subject for
participating in the trial.
(l)  The anticipated expenses, if any, to the subject for participating in the
trial.
(m)  That the subject's participation in the trial is voluntary and that the
subject may refuse to participate or withdraw from the trial, at any time,
without penalty or loss of  benefits to which the subject is otherwise
entitled. 
(n)  That the monitor(s), the auditor(s), the IRB/IEC, and the regulatory
authority(ies) will be granted direct access to the subject's original medical
records for verification of clinical trial procedures and/or data, without
violating the confidentiality of the subject, to the extent permitted by the
applicable laws and regulations and that, by signing a written informed
consent form, the subject or the subject's legally acceptable representative
is authorizing such access.
(o)  That records identifying the subject will be kept confidential and, to the
extent permitted by the applicable laws and/or regulations, will not be made
publicly available.  If the results of the trial are published, the subject’s
identity will remain confidential. 
(p)  That the subject or the subject's legally acceptable representative will
be informed in a timely manner if information becomes available that may
be relevant to the subject's willingness to continue participation in the trial. 
(q)  The person(s) to contact for further information regarding the trial and
the rights of trial subjects, and whom to contact in the event of trial-related
injury. 

20
(r)  The foreseeable circumstances and/or reasons under which the subject's
participation in the trial may be terminated. 
(s)  The expected duration of the subject's participation in the trial.
(t)  The approximate number of subjects involved in the trial. 
4.8.11  Prior to participation in the trial, the subject or the subject's legally
acceptable representative should receive a copy of the signed and dated written
informed consent form and any other written information provided to the subjects. 
During a subject’s participation in the trial, the subject or the subject’s legally
acceptable representative should receive a copy of the signed and dated consent
form updates and a copy of any amendments to the written information provided
to subjects.
4.8.12  When a clinical trial (therapeutic or nontherapeutic) includes subjects who
can only be enrolled in the trial with the consent of the subject’s legally acceptable
representative (e.g., minors, or patients with severe dementia), the subject should
be informed about the trial to the extent compatible with the subject’s
understanding and, if capable, the subject should assent, sign and personally date
the written informed consent.
4.8.13  Except as described in 4.8.14, a nontherapeutic trial (i.e., a trial in which
there is no anticipated direct clinical benefit to the subject) should be conducted in
subjects who personally give consent and who sign and date the written informed
consent form.
4.8.14  Nontherapeutic trials may be conducted in subjects with consent of a
legally acceptable representative provided the following conditions are fulfilled:
(a)  The objectives of the trial cannot be met by means of a trial in subjects
who can give informed consent personally.
(b)  The foreseeable risks to the subjects are low.
(c)  The negative impact on the subject’s well-being is minimized and low.
(d)  The trial is not prohibited by law.
(e)  The approval/favorable opinion of the IRB/IEC is expressly sought on
the inclusion of such subjects, and the written approval/favorable opinion
covers this aspect. 

21
Such trials, unless an exception is justified, should be conducted in patients having
a disease or condition for which the investigational product is intended.  Subjects
in these trials should be particularly closely monitored and should be withdrawn if
they appear to be unduly distressed.
4.8.15  In emergency situations, when prior consent of the subject is not possible,
the consent of the subject's legally acceptable representative, if present, should be
requested.  When prior consent of the subject is not possible, and the subject’s
legally acceptable representative is not available, enrollment of the subject should
require measures described in the protocol and/or elsewhere, with documented
approval/favorable opinion by the IRB/IEC, to protect the rights, safety, and well-
being of the subject and to ensure compliance with applicable regulatory
requirements.  The subject or the subject's legally acceptable representative should
be informed about the trial as soon as possible and consent to continue and other
consent as appropriate (see section 4.8.10) should be requested.
4.9
Records and Reports
4.9.1  The investigator should ensure the accuracy, completeness, legibility, and
timeliness of the data reported to the sponsor in the CRFs and in all required
reports.
4.9.2  Data reported on the CRF, which are derived from source documents,
should be consistent with the source documents or the discrepancies should be
explained.
4.9.3  Any change or correction to a CRF should be dated, initialed, and explained
(if necessary) and should not obscure the original entry (i.e., an audit trail should
be maintained); this applies to both written and electronic changes or corrections
(see section 5.18.4(n)).  Sponsors should provide guidance to investigators and/or
the investigators' designated representatives on making such corrections.  Sponsors
should have written procedures to assure that changes or corrections in CRFs
made by sponsor's designated representatives are documented, are necessary, and
are endorsed by the investigator.  The investigator should retain records of the
changes and corrections.
4.9.4  The investigator/institution should maintain the trial documents as specified
in Essential Documents for the Conduct of a Clinical Trial (see section 8.) and as
required by the applicable regulatory requirement(s).  The investigator/institution
should take measures to prevent accidental or premature destruction of these
documents.

22
4.9.5  Essential documents should be retained until at least 2 years after the last
approval of a marketing application in an ICH region and until there are no
pending or contemplated marketing applications in an ICH region or at least 2
years have elapsed since the formal discontinuation of clinical development of the
investigational product.  These documents should be retained for a longer period,
however, if required by the applicable regulatory requirements or by an agreement
with the sponsor.  It is the responsibility of the sponsor to inform the
investigator/institution as to when these documents no longer need to be retained
(see section 5.5.12).
4.9.6  The financial aspects of the trial should be documented in an agreement
between the sponsor and the investigator/institution.
4.9.7  Upon request of the monitor, auditor, IRB/IEC, or regulatory authority, the
investigator/institution should make available for direct access all requested trial-
related records. 
4.10
Progress Reports
4.10.1  Where required by the applicable regulatory requirements, the investigator
should submit written summaries of the trial’s status to the institution.  The
investigator/institution should submit written summaries of the status of the trial to
the IRB/IEC annually, or more frequently, if requested by the IRB/IEC.
4.10.2  The investigator should promptly provide written reports to the sponsor,
the IRB/IEC (see section 3.3.8), and, where required by the applicable regulatory
requirements, the institution on any changes significantly affecting the conduct of
the trial, and/or increasing the risk to subjects.
4.11
Safety Reporting
4.11.1  All serious adverse events (SAEs) should be reported immediately to the
sponsor except for those SAEs that the protocol or other document (e.g.,
Investigator's Brochure) identifies as not needing immediate reporting.  The
immediate reports should be followed promptly by detailed, written reports.  The
immediate and follow-up reports should identify subjects by unique code numbers
assigned to the trial subjects rather than by  the subjects' names, personal
identification numbers, and/or addresses.  The investigator should also comply
with the applicable regulatory requirement(s) related to the reporting of
unexpected serious adverse drug reactions to the regulatory authority(ies) and the
IRB/IEC.

23
4.11.2  Adverse events and/or laboratory abnormalities identified in the protocol as
critical to safety evaluations should be reported to the sponsor according to the
reporting requirements and within the time periods specified by the sponsor in the
protocol.
4.11.3  For reported deaths, the investigator should supply the sponsor and the
IRB/IEC with any additional requested information (e.g., autopsy reports and
terminal medical reports).
4.12
Premature Termination or Suspension of a Trial
If the trial is terminated prematurely or suspended for any reason, the
investigator/institution should promptly inform the trial subjects, should assure appropriate
therapy and follow-up for the subjects, and, where required by the applicable regulatory
requirement(s), should inform the regulatory authority(ies).  In addition:
4.12.1  If the investigator terminates or suspends a trial without prior agreement of
the sponsor, the investigator should inform the institution, where required by the
applicable regulatory requirements, and the investigator/institution should
promptly inform the sponsor and the IRB/IEC, and should provide the sponsor and
the IRB/IEC a detailed written explanation of the termination or suspension.
4.12.2  If the sponsor terminates or suspends a trial (see section 5.21), the
investigator should promptly inform the institution, where required by the
applicable regulatory requirements, and the investigator/institution should
promptly inform the IRB/IEC and provide the IRB/IEC a detailed written
explanation of the termination or suspension.
4.12.3  If the IRB/IEC terminates or suspends its approval/favorable opinion of a
trial (see sections 3.1.2 and 3.3.9), the investigator should inform the institution,
where required by the applicable regulatory requirements, and the
investigator/institution should promptly notify the sponsor and provide the sponsor
with a detailed written explanation of the termination or suspension.
4.13
Final Report(s) by Investigator/Institution
Upon completion of the trial, the investigator should, where required by the applicable
regulatory requirements, inform the institution, and the investigator/institution should
provide the sponsor with all required reports, the IRB/IEC with a summary of the trial’s
outcome, and the regulatory authority(ies) with any report(s) they require of the
investigator/institution.
