Start date: 2015-07-23; Completion date: 2019-02-27
Enrollment: 387 participants; Allocation: RANDOMIZED; Intervention model: PARALLEL

Brief summary:
Participants with agitation secondary to dementia of the Alzheimer's type. The diagnosis of probable Alzheimer's disease (AD) was to be based on the "2011 Diagnostic Guidelines for Alzheimer's Disease" issued by the National Institute on Aging (NIA)-Alzheimer's Association (AA) workgroups.

Detailed description:
Eligible participants for this study must have had a diagnosis of probable AD and must have had clinically meaningful agitation secondary to AD.

This was to be a multicenter, randomized, placebo-controlled study, consisting of 12 weeks of treatment.

Approximately 380 participants were to be enrolled at approximately 60 centers in North America.

Study medication was to be administered orally twice-daily from Day 1 through Day 85. Screening was to occur within approximately 4 weeks prior to randomization. Following screening procedures for assessment of inclusion and exclusion criteria, eligible participants were to be randomized into the study.

Arms: arm 1: Participants received matching placebo orally twice daily (BID) for 6 weeks (Days 1-42) in Stage 1. Participants who completed Stage 1 were eligible to Participate in Stage 2. arm 2: Participants received AVP-786-18 mg orally once daily (QD) in the morning and placebo orally QD in the evening for the first 7 days, followed by AVP-786-18 mg orally BID for the remaining 5 weeks (Days 8-42). Participants who completed Stage 1 were eligible to participate in Stage 2. arm 3: Participants received AVP-786-18 mg orally QD in the morning and placebo orally QD in the evening for the first 7 days, followed by AVP-786-18 mg orally BID for 2 weeks (Days 8-21). From Day 22, participants received AVP-786-28 mg orally BID for the remaining 3 weeks. Participants who completed Stage 1 were eligible to participate in Stage 2. arm 4: Participants who received matching placebo orally BID for 6 consecutive weeks in Stage 1 were re-randomized in Stage 2 to receive the study drug or placebo from Day 43 to Day 85. arm 5: Participants who received AVP-786-18 mg in Stage 1 continued to receive AVP-786-18 mg orally BID for the 6 weeks (Days 43-85) in Stage 2.. arm 6: Participants who received AVP-786-28 mg in Stage 1 continued to receive AVP-786-28 mg orally BID for 6 weeks (Days 43-85) in Stage 2 arm 7: Participants who were placebo responders or non-responders in Stage 1 received AVP-786-18 for 1 week, orally, QD, followed by AVP-786-18 BID for 2 weeks; followed by AVP-786-28 BID for the last 3 weeks. arm 8: Participants who were placebo responders or non-responders in Stage 1 received AVP-786-28 for 1 week, orally, QD, followed by AVP-786-28 BID for 2 weeks; followed by AVP-786-28 BID for the last 3 weeks.

STUDY SYNOPSIS 
Title: A Phase 3, multicenter, randomized, double-blind, placebo-controlled, sequential parallel 
comparison design (SPCD) 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 380 patients will be enrolled at approximately 60 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, SPCD study 
comprising 2 stages.  A schematic of the study design is presented in Figure 1. 
Duration: Patients will be enrolled in the study for approximately 16 weeks; with up to 4-week screening 
period and 12-week treatment period.  The treatment period is divided equally into 2 stages of 6 weeks 
each, Stage 1 and Stage 2.

Study Treatment:  The investigational product is AVP-786 (deuterated [d6]-dextromethorphan 
hydrobromide [d6-DM; INN:deudextromethorphan]/quinidine sulfate [Q]).  Two doses of AVP-786 will 
be evaluated; 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.  
Control:  Placebo capsules of identical appearance to study medication will be used as control. 
Randomization/Stratification:  Eligible patients will be randomized into the study in a 
 
(active:active:placebo) ratio to receive either AVP-786-28/4.9 capsules, AVP-786-18/4.9 capsules, or 
matching placebo capsules in Stage 1.  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.  
Stage 1 
• 
Patients randomized to receive AVP-786-28/4.9 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 3-week duration of Stage 1.  
• 
Patients randomized to receive AVP-786-18/4.9 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 the remaining 5-week duration of Stage 1. 
• 
Patients randomized to receive placebo will be dosed with placebo BID during Stage 1.  
Stage 2: 
Patients who complete Stage 1 are eligible to participate in Stage 2 of the study.  In Stage 2, patients will 
be assigned to study treatment as follows: 
• 
Patients who received AVP-786 in Stage 1 will continue to receive the same dose of AVP-786 BID 
(either AVP-786-18/4.9 or AVP-786-28/4.9) for the entire 6-week duration of Stage 2. 
• 
Patients who received placebo in Stage 1 will be further stratified into two sub-groups (“responders” 
and “non-responders”) on Visit 4 (Day 43) based on their treatment response.  Patients will be 
considered “responders” if their CGIS-Agitation score is ≤ 3 at Visit 4 (Day 43) and their NPI 
Agitation/Aggression domain score has decreased by ≥ 25% from baseline.  Patients who do not meet 
these criteria will be considered “non-responders”.  Patients within each placebo sub-group will be re-
randomized in a 
 (active:active:placebo) ratio to receive either AVP-786-18/4.9, AVP-786-
28/4.9 capsules, or matching placebo capsules. 
o Patients who are re-randomized to placebo will continue to receive placebo BID for the entire 
6-week duration of Stage 2.

o Patients who are re-randomized to AVP-786-28/4.9 will receive AVP-786-18/4.9 once a day 
in the morning and placebo in the evening for the first 7 days of Stage 2 (Days 43-49).  From 
Day 50, patients will receive AVP-786-18/4.9 BID for 14 days (Days 50-63).  From Day 64, 
patients will receive AVP-786-28/4.9 BID for the remaining 3 weeks of the study. 
o Patients who are re-randomized to AVP-786-18/4.9 will receive AVP-786-18/4.9 once a day 
in the morning and placebo in the evening for the first 7 days of Stage 2 (Days 43-49).  From 
Day 50, patients will receive AVP-786-18/4.9 BID for the remaining 5 weeks of 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).  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-Agitation 
(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 analysis will be based on the SPCD method.  The primary efficacy endpoint of the 
study is the change from Baseline to Week 6 (Day 43, Stage 1) and from Week 6 to Week 12 (Day 85, 
Stage 2) in the composite CMAI scores.  A weighted test statistics combining treatment effects from 
Stage 1 and 23 will be used.  The treatment effect in each stage will be estimated by using a likelihood-
based linear mixed effects model repeated measures (MMRM) on observed data.  Data from Stage 1 
placebo non-responders who are re-randomized into Stage 2 will be used to estimate the Stage 2 treatment 
effect.  Appropriate procedures to control type I error will be implemented and the details will be 
provided in the Statistical Analysis Plan (SAP).    
Secondary efficacy endpoints include change from Baseline to Week 6 (Day 43, Stage 1) and from 
Week 6 to Week 12 (Day 85, Stage 2) 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, CGIS-
Agitation, ADCS-CGIC-Overall, ADAS-cog; and change from Baseline to Week 12 for GMHR.   
Safety Analyses 
Safety measures will be summarized by Stage 1, Stage 2, and the 2 stages combined.  
Sample Size Calculation 
Power calculations were performed assuming a bivariate normal distribution for the primary efficacy 
endpoint with AVP-786-28/4.9 (high dose) versus placebo.  
 
 
 
 
 
  
  
 
 
  To control the

overall type I error rate at 
level, the null hypothesis about the low dose AVP-786-18/4.9 will be 
tested only if the null hypothesis about the high dose is rejected.

STUDY DESIGN 
This is a phase 3, multicenter, randomized, double-blind, placebo-controlled, SPCD study of 12-week 
treatment duration.  The treatment period is divided equally into 2 stages of 6 weeks each, Stage 1 and 
Stage 2.

Study Day 
Day -28 to -1 
Day 1 to 42 
Day 43 to 85 
 
There will be 8 scheduled clinic visits including a screening visit, and 2 safety follow-up phone visits 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).  Safety follow-up phone calls will be made on Days 29 (Week 4) and 
71 (Week 10).  A schematic of the study design is depicted in Figure 1. 
Approximately 380 patients will be enrolled at approximately 60 centers in North America.   
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 the 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.   
Stage 1 
Following screening procedures for assessment of inclusion and exclusion criteria, eligible patients will 
be randomized into the study in a 
 (active:active:placebo) ratio to receive either AVP-786-28/4.9 
capsules, AVP-786-18/4.9 capsules, or matching placebo capsules.  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 receive AVP-786-28/4.9 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 3-week duration of Stage 1.  
• 
Patients randomized to receive AVP-786-18/4.9 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 the remaining 5-week duration of Stage 1. 
• 
Patients randomized to receive placebo will be dosed with placebo BID during Stage 1.

Stage 2: 
Patients who complete Stage 1 are eligible to participate in the 6-week Stage 2 of the study.  In Stage 2, 
patients will be assigned to study treatment as follows: 
• 
Patients who received AVP-786 in Stage 1 will continue to receive the same dose of AVP-786 BID 
(either AVP-786-28/4.9 or AVP-786-18/4.9) for the entire 6-week duration of Stage 2. 
• 
Patients who received placebo in Stage 1 will be further stratified into two sub-groups (“responders” 
and “non-responders”) on Visit 4 (Day 43) based on their treatment response.  Patients will be 
considered “responders” if 
 
 
 will be considered “non-responders”.   Patients within each placebo sub-group will be 
re-randomized in a 
 (active:active:placebo) ratio to receive either AVP-786-28/4.9 capsules, 
AVP-786-18/4.9 capsules, or matching placebo capsules. 
o Patients who are re-randomized to placebo will continue to receive placebo BID for the entire 
6-week duration of Stage 2. 
o Patients who are re-randomized to AVP-786-28/4.9 will receive AVP-786-18/4.9 once a day 
in the morning and placebo in the evening for the first 7 days of Stage 2 (Days 43-49).  From 
Day 50, patients will receive AVP-786-18/4.9 BID for 14 days (Days 50-63).  From Day 64, 
patients will receive AVP-786-28/4.9 BID for the remaining 3 weeks of the study. 
o Patients who are re-randomized to AVP-786-18/4.9 will receive AVP-786-18/4.9 once a day 
in the morning and placebo in the evening for the first 7 days of Stage 2 (Days 43-49).  From 
Day 50, patients will receive AVP-786-18/4.9 BID for the remaining 5 weeks of the study.

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.22  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.

4.3 
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 withdraw prior to study completion will be asked to return to the clinic to complete the 
Visit 6 (end of study) assessments.   
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.

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 the 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.  For Visits 2 (Day 8) and 2.1 (Day 15), the morning dose of study 
medication can be administered at home if the visit will occur within 2 hours of dosing; the time of dosing 
should be noted by the patient/caregiver.  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.  
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) 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.

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. 
Stage 1 
Eligible patients will be randomized to receive AVP-786-28/4.9 capsules, AVP-786-18/4.9 capsules, or 
matching placebo capsules in a 
 ratio on Day 1 (Baseline, Stage 1) in a double-blind manner 
according to a randomization scheme devised by Avanir or its representative and managed within an 
IWRS.  The randomization will be stratified by 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.   
Stage 2 
Re-randomization will occur for patients who were assigned to placebo in Stage 1.  The patient number 
will not be re-assigned; it will remain the same in both stages of the study.   
• 
Patients who receive placebo in Stage 1 will be further stratified into two sub-groups (“responders” 
and “non-responders”) based on their treatment responses.  Patients will be considered “responders” 
if 
 
  Patients who do not meet 
 will be 
considered “non-responders”.  Patients within each placebo sub-group will be re-randomized in a 
 (active:active:placebo) ratio to receive either AVP-786-18/4.9, AVP-786-28/4.9 capsules, or 
matching placebo capsules.  
• 
Patients who receive placebo and who drop out early in Stage 1 will also be assigned a re-
randomization treatment in the same manner as the other placebo patients.  Their “responders” and 
“non-responders” status will be based on their treatment responses using measurements at their early 
termination visit.     
• 
Patients who receive AVP-786 in Stage 1 will not be re-randomized and will continue to receive the 
same dose of AVP-786 BID (either AVP-786-18/4.9 or AVP-786-28/4.9) for the entire 6-week 
duration of Stage 2.

Page 42 
 
5.3.2 
Blinding/Masking 
Blinding will be maintained by providing capsules of the 2 doses 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 blister cards 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.

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.

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 (Appendix 2) is used to 
assess the frequency of manifestations of agitated behaviors in elderly persons.  It consists of 29 agitated 
behaviors 
 
 
 
  
 
.  Each of 
the 29 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, Appendix 2) 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).  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-786-301 
Version 4.0  
 
 
Page 46 
 
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 (Appendix 4) 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 trials26–30 and is easy and quick to administer, provided 
that the clinician knows the patient well.31  
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.32–34 
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 (Appendix 5) (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-786-301 
Version 4.0  
 
 
Page 47 
 
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 (Appendix 6) 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)35,36 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) and Day 85 (Visit 6) 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.  The 
mADCS-CGIC-Agitation must be administered by the same rater at each visit. 
6.1.6 
Zarit Burden Interview (ZBI) 
The ZBI (Appendix 7) 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.37  It is the most commonly used 
scale for measuring burden in caregivers’ of patients with dementia and also other illnesses.38  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).39  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-786-301 
Version 4.0  
 
 
Page 48 
 
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 (Appendix 8) 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.31 
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 (Appendix 9) is a scale used to evaluate health related quality of life in patients with 
dementia and their caregivers.40  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 (Appendix 10) was designed to evaluate the cognitive and non-cognitive behavioral 
dysfunction characteristics of patients with AD.41  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 (Appendix 11) was specifically developed to assess signs and symptoms of major depression 
in patients with dementia.42  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-786-301 
Version 4.0  
 
 
Page 49 
 
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 (Appendix 12) is used to calculate healthcare costs associated with dementia.43  It evaluates 
dementia patients’ utilization of formal and informal healthcare resources, including hospitalizations and 
doctor visits, living assistance, and time spent by non-professional caregivers.  Within the context of 
clinical trials, the RUD is often used to determine the cost effectiveness of new pharmaceutical 
treatments.44   
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 (Appendix 13) 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.45  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.

Safety 
6.3.1 
Adverse Events 
6.3.1.1 
Definitions 
An adverse event (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;

Protocol 15-AVP-786-301 
Version 4.0

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.

6.3.1.3 
Reporting 
Caregivers will be queried regarding AEs at each clinic visit after the screening visit (Baseline [Day 1], 
Days 8, 15, 22, 43, 64, and 85 [Visits 2-6]) 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 will be followed up until 30 days.  
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:  
 
E-mail: 
 
SAE hotline (24-hour/7 days a week) 
Phone: 
 
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

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) and Day 43 (Visit 4), 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 (Appendix 14) is a prospective scale that assesses treatment-emergent suicidal thoughts and 
behaviors.46  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), and Day 85 (Visit 6).  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 (Appendix 15) 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.47  It requires only 5 to 10 minutes for a trained rater to 
administer it. 


 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-301

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 (Appendix 16) 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.48,49  
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 (Appendix 17) 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.50  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).  
6.4 
Schedule of Evaluations and Procedures 
A schedule of evaluations and procedures for both Stage 1 and Stage 2 is provided in Table 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 
The efficacy measures are assessed in each of the two stages of the trial.  For the primary efficacy 
analysis, as well as for all other efficacy analyses, the SPCD method will be used to combine data from 
Stage 1 and 2.  Data from Stage 1 placebo non-responders who are re-randomized into Stage 2 will be 
used to estimate Stage 2 treatment effect.  
8.3.1 
Study Endpoints 
Primary efficacy endpoint: 
The primary efficacy endpoint is the change from Baseline to Week 6 (Day 43, Stage 1) and from Week 6 
to Week 12 (Day 85, Stage 2) in the composite CMAI scores. 
 
Secondary efficacy endpoints: 
The secondary efficacy endpoints are the change from Baseline to Week 6 (Day 43, Stage 1) and from 
Week 6 to Week 12 (Day 85, Stage 2) in the following measures:   
• mADCS-CGIC-Agitation   
• NPI – Agitation/Aggression domain score and Caregiver Distress score

• NPI - Irritability/Lability domain 
• Total NPI 
• CGIS-Agitation  
• ADCS-CGIC-Overall  
• PGIC  
• DEMQOL  
• CSDD  
• ADAS-cog   
• RUD 
• GMHR (change from Baseline to Week 12 (Day 85) 
8.3.2 
Primary Efficacy Analysis 
The primary efficacy endpoint is the change from Baseline to Week 6 (Day 43, Stage 1) and from Week 6 
to Week 12 (Day 85, Stage 2) in the composite CMAI scores.  The primary efficacy analysis will be 
based on SPCD method using a weighted test statistics combining treatment effects from Stage 1 and 2.3  
Data from Stage 1 placebo non-responders who are re-randomized into Stage 2 will be used to estimate 
Stage 2 treatment effect. 
For the primary efficacy endpoint, the null hypothesis is that there is no treatment effect in Stage 1 and 
Stage 2 and it will be tested against the alternative that there is a treatment effect in at least one of the 2 
stages.  The treatment effect in each stage will be estimated by using a likelihood-based linear mixed 
effects model repeated measures (MMRM) on observed data.  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 randomization stratification factors.  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. 
The 2 primary comparisons are AVP-786-28/4.9 vs. placebo and AVP-786-18/4.9 vs. placebo.  An 
appropriate multiple comparison procedure will be used to control the overall type I error at 2-sided α = 
0.05.   
8.3.3 
Secondary Efficacy Analyses 
Secondary efficacy endpoints include change from Baseline to Week 6 (Day 43, Stage 1) and from 
Week 6 to Week 12 (Day 85, Stage 2) 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 change from Baseline to Week 12 for GMHR.   
Treatment comparison tests using similar SPCD method as the primary efficacy analysis will be 
performed.  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 treatment comparisons (high dose vs. placebo, low dose vs. 
placebo) and the secondary endpoints tested.  The testing procedure will be pre-specified in the statistical 
analysis plan (SAP) before un-blinding the study.  
 
 
  Detailed analyses will 
be described in the SAP. 
8.4 
PK/PD Analysis 
Plasma concentrations of d6-DM, its metabolites, and Q will be measured and results will be summarized 
descriptively overall 
.  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. 
8.5 
  
 
    
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.  All safety measures will be summarized by Stage 1, Stage 2, and the 2 stages 
combined. 
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.

Page 71 
 
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 pre-specified in the SAP. 
8.7 
Sample Size Calculations  
Power calculations were performed assuming a bivariate normal distribution for the primary efficacy 
endpoint with AVP-786-28/4.9 (high dose) versus placebo.

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 (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 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.  


 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-301 
Version 4.0  
 
 
Page 74 
 
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-786-301 
Version 4.0  
 
 
Page 75 
 
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 calls 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 
 at Baseline (Day 1) and for 


 
AVANIR PHARMACEUTICALS, INC 
Protocol 15-AVP-786-301 
Version 4.0  
 
 
Page 76 
 
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.

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.

Not applicable. 
2.0 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. 
3.0 Study Design 
3.1 General Description 
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study with a duration of 12 
weeks, consisting of 2 consecutive double-blind treatment stages (Stage 1 and Stage 2) of 6 weeks 
duration each.  The study utilizes a sequential parallel comparison design (SPCD) with a re-
randomization for Stage 2. Table 1 provides an overview of the study duration for each stage:

Days 1 to 42 
Days 43 to 85 
 
Approximately 380 patients with a diagnosis of probable Alzheimer’s disease (AD) and clinically 
meaningful moderate/severe agitation secondary to AD will be enrolled at approximately 60 research 
centers in the United States. There will be 8 scheduled clinic visits including a screening visit and 2 safety 
follow-up phone visits in the study.  Clinic visits include Screening, Baseline (Day 1), and Weeks 1, 2, 3, 
6, 9, and 12. Safety follow-up phone calls will occur on Week 4 and Week 10.  Visits at Weeks 6, 9 and 
12 correspond to Stage 2 Baseline, Week 3 and Week 6. The schedule of events is provided in Table 2:

Note: 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. 
1 
Study visits have a +/- 3-day window except Screening, Visit 2, and phone calls. Screening, Visit 2, and phone calls have a +3-day window. The screening period 
may be extended after discussion with and approval by the medical monitor. 
2 
Phone call should be made to patient/caregiver to collect adverse events and query on concomitant medication use 
3 
Early termination visit for patients who withdraw prior to study completion 
4 
Patients who terminate early from the study or 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. 
5 
For each patient, a protocol eligibility form will be completed 
6 
Weight should be measured only at the Baseline Visit and Visit 6 
7 
The ADCS-CGIC-Overall baseline evaluation worksheet should be completed to record baseline information for assessing change at Visits 4 and 6 
8 
The mADCS-CGIC-Agitation baseline evaluation worksheet should be completed to record baseline information for assessing change at Visits 4 and 6 
9 
Only the TUG test should be performed for risk assessment of falls at Visits 4 and 6 
10 
ECG should be performed in triplicate at the Screening visit 
11 
ECG to be performed pre-dose and post-dose 
12 
Only the Agitation/Aggression domain of the NPI should be performed at the Screening Visit, Visit 2, and Visit 2.1 
13 
The proxy version is to be rated by the caregiver. The non-proxy version is to be rated only by patients with an MMSE score of ≥ 10 at baseline 
14 
ADAS-cog is to be rated only by patients with an MMSE score of ≥ 10 at baseline 
15 
PGIC is to be rated by the caregiver 
16 
The morning dose of study medication can be administered at home if the visit will occur within 2 hours of dosing; the time of dosing should be 
noted by the patient/caregiver. The blister card and diary card should be returned to the patient/caregiver after reviewing for compliance. 
17 
Thyroid function tests (TSH, and reflex T3 and T4 if TSH is abnormal) should be performed at the Screening visit. Glycosylated hemoglobin (HbA1c) 
test should be performed at the Screening visit and Visit 6.

Week 3, Week 6, Week 9, and Week 12.  Additionally, the Agitation/Aggression domain of the NPI will be 
administered to the patient’s caregiver at Screening.  
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 
• 
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 frequency and severity, yielding a domain score.  Domain scores range from 
1 to 12 and are calculated using the following formula:  
domain score = frequency x severity 
where, frequency and severity are rated according to the following scales: 
Frequency 
Severity 
• 
1 = Rarely – less than once per week 
• 
2 = Sometimes – about once per week 
• 
3 = Often – several times per week but 
less than every day 
• 
4 = Very often – once or more per day 
• 
1 = Mild – produces little distress in the 
patient 
• 
2 = Moderate – more disturbing to the 
patient but can be redirected by the 
caregiver 
• 
3 = Severe – very disturbing to the patient 
and difficult to redirect 
Frequency and severity rating scales have defined anchor points to enhance the reliability of caregiver 
responses.  Caregiver distress is also rated for each positive neuropsychiatric symptom domain using the 
following anchored scores: 
Distress 
• 
0 = Not at all 
• 
1 = Minimally (almost no change in work routine) 
• 
2 = Mildly (some change in work routine but little time rebudgeting required) 
• 
3 = Moderately (disrupts work routine, requires time rebudgeting) 
• 
4 = Severely (disruptive, upsetting to staff and other residents, major time infringement) 
• 
5 = Very Severely or Extremely (very disruptive, major source of distress for staff and other 
residents, requires time usually devoted to other residents or activities) 
The NPI nursing-home (NPI-NH) version will be used for patients from in-patient or assisted living 
facilities.  The questions in the NPI-NH are rephrased for professional caregivers who may not know the 
patient 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. 
A total NPI score is calculated by adding the scores of all 12 domain scores together. The possible total 
scores are from 0 to 144. The NPI Total Score will be unevaluable if less than 10 of the 12 items are 
recorded. If 10 or 11 of the 12 items are available, then the total score is the mean of the available scores 
times 12. All imputed scores are rounded to the first decimal place. The distress score is not included in 
the total NPI score.

The total caregiver distress score is generated by adding together the scores of all 12 domains of the NPI 
distress questions.  Scores range from 0 to 60 with a higher score indicating more distress. Total score 
calculation with missing items follows the same algorithm as the NPI total score. 
4.1.3 Clinical Global Impression of Severity of Illness-Agitation 
(CGIS-Agitation) 
The CGIS-Agitation is an observer-rated scale that measures illness severity and will be assessed at 
Screening, Baseline, Week 6, and Week 12. 
The clinician is asked to rate the patient relative to their past experience with other patients with the same 
diagnosis, with or without collateral information.  The CGIS-Agitation is a 7-point scale and will be 
assessed for severity of agitation.  A value of 0 is given to patients who are not assessed.  The 7-point 
scale for CGIS-Agitation is the following: 
Severity of Agitation Scores 
• 
0 = Not assessed 
• 
1 = Normal, not at all ill 
• 
2 = Borderline ill 
• 
3 = Mildly ill 
• 
4 = Moderately ill 
• 
5 = Markedly ill 
• 
6 = Severely ill 
• 
7 = Among the most extremely ill patient 
4.1.4 Alzheimer’s Disease Cooperative Study – Clinical Global Impression of 
Change Rating (ADCS-CGIC-Overall) 
The ADCS version of the Clinical Global CGIC, referred to as ADCS-CGIC-Overall, provides a reliable 
means to assess change from a baseline level of global function within the timeframe of a clinical trial.  
The ADCS-CGIC-Overall focuses on clinicians’ observations of change in the patient’s cognitive, 
functional, and behavioral performance since the beginning of the 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 by an independent evaluator.  The response for the ADCS-CGIC-Overall 
will consist of one of the following: 
Overall Clinical Status Responses 
• 
1 = Marked Improvement 
• 
2 = Moderate Improvement  
• 
3 = Minimal Improvement 
• 
4 = No Change 
• 
5 = Minimal Worsening 
• 
6 = Moderate Worsening 
• 
7 = Marked Worsening 
The baseline ADCS-CGIC-Overall evaluation will be conducted at the Baseline visit.  The 
ADCS-CGIC-Overall will be assessed at Week 6 and Week 12 for change in Overall Clinical Status.  At 
Week 6, change from the Baseline visit will be assessed.  At Week 12, change from Week 6 and change 
from the Baseline visit will be assessed. 
4.1.5 Modified Alzheimer’s Disease Cooperative Study – Clinical Global 
Impression of Change Rating (mADCS-CGIC-Agitation) 
The mADCS-CGIC-Agitation is a modified version of the ADCS-CGIC containing additional questions 
related to agitation and an assessment of the Clinician’s Impression of Change focused specifically on 
agitation.  The response for the mADCS-CGIC-Agitation will consist of one of the following:

Responses 
• 
1 = Marked Improvement 
• 
2 = Moderate Improvement  
• 
3 = Minimal Improvement 
• 
4 = No Change 
• 
5 = Minimal Worsening 
• 
6 = Moderate Worsening 
• 
7 = Marked Worsening 
The baseline mADCS-CGIC-Agitation evaluation will be conducted at the Baseline visit.  The 
mADCS-CGIC-Agitation will be assessed at Week 6 and Week 12 for change in agitation.  At Week 6, 
change from the Baseline visit will be assessed.  At Week 12, change from Week 6 and change from the 
Baseline visit will be assessed.  
4.1.6 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 and will 
be assessed at Baseline, Week 6, and Week 12.  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.  Each question is rated on the following 5-point scale: 
Zarit Burden Interview Scores for Individual Questions 
• 
0 = Never 
• 
1 = Rarely 
• 
2 = Sometimes 
• 
3 = Quite Frequently 
• 
4 = Nearly Always 
The ZBI is scored by summing the responses of the individual questions and ranges from 0 to 88.  Higher 
scores indicate greater caregiver distress. The ZBI score will be unevaluable if 4 or more of the 22 items 
are missing. If 19 to 21 of the 22 items are available, then the total score is the mean of the available 
scores times 22. All imputed scores are rounded to the first decimal place.   
4.1.7 Patient Global Impression of Change (PGIC) 
The PGIC is a 7-point scale used to assess treatment response and will be assessed and rated by the 
patient’s caregiver at Week 6 and Week 12 and will focus on the patient’s agitation.  The response values 
for the PGIC are provided below: 
Patient Global Impression of Change Scale 
• 
1 = Very much improved 
• 
2 = Much improved  
• 
3 = Minimally improved 
• 
4 = No change 
• 
5 = Minimally worse 
• 
6 = Much worse 
• 
7 = Very much worse 
4.1.8   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.  There are 2 versions of the DEMQOL, a 28-item version (rated by the patient) and a 31-item 
version (DEMQOL-proxy, rated by the caregiver).  The following provides the response categories for the 
individual DEMQOL questions and the overall quality of life question: 
DEMQOL Responses for Individual Questions  
Overall Quality of Life Question 
• 
1 = A lot 
• 
1 = Very good

• 
2 = Quite a bit 
• 
3 = A little 
• 
4 = Not at all 
• 
2 = Good 
• 
3 = Fair 
• 
4 = Poor 
The DEMQOL-proxy (and DEMQOL for patients with a Mini Mental State Examination (MMSE) score ≥ 10 
at the Baseline visit) will be assessed at Baseline, Week 6, and Week 12. 
Scores for DEMQOL Item 1, 3, 5, 6, 10, 29, DEMQOL-proxy item 1, 4, 6, 8, 11, 32, need to be reversed 
for analysis, i.e., 4=A lot, 3=Quite a bit, 2=A little, 1=Not at all. Total score is derived by sum of all item 
scores with item 29 in DEMQOL and item 32 in DEMQOL-proxy being excluded. Missing item handling for 
DEMQOL, 1) count the number of missing item for question 1 to 28, 2) if the number < 15, set the missing 
item values to the mean of the non-missing item 1 to 28, then add them up; if the number of missing >= 
15, then the total is missing. Missing item handling for DEMQOL-proxy, 1) count the number of missing 
item for question 1 to 31, 2) if the number < 16, set the missing item values to the mean of the non-
missing item 1 to 31, then add them up; if the number of missing >= 16, then the total is missing. 
4.1.9 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 and will be assessed at Baseline, Week 6, and Week 12 for patients 
with an MMSE score ≥ 10 at the Baseline visit.  The cognitive subscale (ADAS-cog) consists of 11 
subsets related to memory, praxis, and language.  Scoring of the individual subsets is specific to each 
particular subset.  The ADAS-cog is scored by summing the 11 subset scores and ranges in scale from 0 
to 70. Scoring for each component of the ADAS-cog is as follows: 
Component 
Measurement 
Scoring 
Word Recall Task 
Mean number of words not 
recalled on 3 trials 
Maximum score = 10 
Naming Task 
Number of objects named 
incorrectly 
0 (0 – 2 items) to 5 (15-17 
items) 
Commands 
Number of correct and incorrect 
commands 
0 (all commands correct) to 5 
(all commands incorrect) 
Constructional Praxis 
Number of drawings correct 
0 (all drawings correct) to 5 (no 
figures drawn, no recognizable 
attempt at drawing any 
side/section of any figure) 
Ideational Praxis

performed correctly 
0 (all components performed 
correctly) to 5 (failure to perform 
5 components) 
Orientation 
One point given for each 
incorrect response 
Maximum score = 8 
Word Recognition 
Mean number of words not 
recognized on 3 trials

4.1.10 Cornell Scale for Depression in Dementia (CSDD) 
The CSDD was developed to assess signs and symptoms of major depression in patients with dementia 
and will be assessed at Screening, Week 6, and Week 12.  Information is elicited through one interview 
with the caregiver and one interview with the patient.  The CSDD has 19 items and each item is rated for 
severity on the following scale: 
Severity Scale for CSDD Items 
• 
0 = Absent 
• 
1 = Mild or intermittent 
• 
2 = Severe 
The CSDD score is calculated by summing the non-missing scores from each item score. Items which 
could not be evaluated are assigned value 0 (Psych Congress Network: 
https://www.psychcongress.com/saundras-corner/scales-screeners/depression/cornell-scale-depression-
dementia-csdd). Scores above 10 indicate probable major depression.  Scores above 18 indicate definite 
major depression.  Scores below 6 as a rule are associated with absence of significant depressive 
symptoms. 
4.1.11 Resource Utilization in Dementia (RUD) 
The RUD is used to calculate healthcare costs associated with dementia and will be assessed at 
Baseline, Week 6, and Week 12.   
The RUD evaluates dementia patients’ utilization of formal and informal healthcare resources, including 
hospitalizations and doctor visits, living assistance, and time spent by nonprofessional caregivers.  The 
RUD is administered as a semi-structured interview with the patient’s primary caregiver.  One section 
focuses on caregiver impact (loss of work and leisure time incurred by the caregiver) and the other 
section focuses on the patient’s use of healthcare resources.  The total healthcare costs associated with 
the patient’s dementia is 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. 
4.1.12 General Medical Health Rating (GMHR) 
The GMHR is a global clinical rating designed to quantify the severity of general co-morbidity in a patient 
with dementia and will be assessed at Screening and Week 12. 
The GMHR is rated according to the following scale: 
GMHR Rating Scale 
 
• 
1 = Poor 
• 
2 = Fair 
• 
3 = Good 
• 
4 = Excellent to very good 
4.1.13 EuroQol 5-Dimension 5-Level (EQ-5D-5L) 
The EQ-5D-5L is composed of a descriptive system and the EQ Visual Analog Scale (EQ VAS).  The 
descriptive system comprises 5 dimensions.  The 5 dimensions and the responses for the dimensions are

8.2 Missing Data Conventions 
Missing data will be handled differently depending on the parameter and analysis.  Analyses that are 
done on ‘observed cases’ will not follow any imputation rules below.  Imputation rules are as follows: 
• 
Missing baseline values will not be imputed in any situation. 
• 
For SPCD and by-stage and visit efficacy analyses (excluding observed case analyses), missing 
data will be imputed within a study stage.  The table below provides imputation rules for last 
observation carried forward (LOCF) and worst observation carried forward (WOCF) + LOCF for 
SPCD. 
 
Missing Imputation for LOCF and WOCF for SPCD 
Stage 
LOCF 
WOCF + LOCF [1] 
   Stage 1  
Impute with last non-missing 
value within Stage 1 including 
Baseline. 
Missing due to lack of 
efficacy – Impute with worst 
non-missing value within 
Stage 1 including Baseline.  
 
Missing due to other reasons 
 - Impute with last non-
missing value within Stage 1 
including Baseline.  
   Stage 2  
Impute with last non-missing 
value within Stage 2 including 
Stage 2 Baseline. 
Missing due to lack of 
efficacy – Impute with worst 
non-missing value within 
Stage 2 including Stage 2 
Baseline. 
 
Missing due to other reasons  
- Impute with last non-missing 
value within Stage 2 including 
Stage 2 Baseline. 
   Stage 2 – Missing data for 
all timepoints 
No imputation 
No imputation 
[1] Only applicable for the primary efficacy endpoints. 
     
• 
Any safety assessments for patients without a Week 12 value will use the last non-missing 
post-baseline observation as EOT.

• 
Missing post-baseline values for by-visit safety data will be summarized using the Visit Windows 
from Section 8.1.  If a value is not available within a given window, then no imputation will be 
done. 
• 
Missing data for AE relationship will be imputed as “Related”. 
• 
Rules for partial dates are provided in Appendices 2 and 3.  These rules will apply to adverse 
events and medications. 
8.3 Treatment Misallocations 
Efficacy data will be summarized, “as randomized”, according to the treatment the patient was 
randomized to regardless of what treatment was actually received. 
Safety data will be summarized, “as treated”, according to the treatment the patient actually received. 
8.4 Data Handling and Transfer 
Data will be entered by investigational sites into a clinical database built with Bioclinica and exported as 
SAS® version 9.4 or higher datasets (SAS Institute, Inc., Cary, NC). Converted datasets are created using 
SAS® and following Clinical Data Interchange Standards Consortium (CDISC) Standard Data Tabulation 
Model conventions (v3.1.3 implementation guide v1.3). Derived analysis datasets are generated using 
SAS® and following standard CDISC Analysis Dataset Model conventions (implementation guide v1.0). 
Data analyses including summary tables, figures, and listings (TFLs) are produced using SAS®. 
Medical history and AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) 
version 18.1 to assign a system organ class (SOC) and preferred term (PT) to each AE.  AEs severity will 
be graded on a 3-point scale and reported in detail as indicated on the eCRF.  
Prior and concomitant medications are coded to preferred drug names using the World Health 
Organization Drug Dictionary Enhanced (WHODRUG DDE, 2015SEP01). 
8.5 Data Screening 
The programming of analysis datasets, tables, figures, and listings (TFL) provides additional data 
screening. Presumed data issues will be output into SAS logs identified by the word “Problem” and 
extracted from the logs by a SAS macro and sent to Data Management. 
Review of a pre-freeze TFL run (Dry Run #1) on clean patients and a post-freeze TFL run (Dry Run #2) 
on the frozen database allow for further data screening prior to database lock (DBL). The post-freeze 
TFLs will be discussed with AVANIR in a data review meeting to identify any final data issues and seek 
corrections prior to DBL. The 
statistician and AVANIR must approve database lock. 
8.6 Data Safety Monitoring Board (DSMB) 
This study is monitored on an ongoing basis by an external data safety monitoring board (DSMB).  Safety 
analyses will be provided to the DSMB approximately every 3 months.  Select efficacy results may be 
included, although no p-values will be provided.  Details of the DSMB can be found in the DSMB charter 
and DSMB SAP. 
9.0 Overall Statistical Considerations 
9.1 Summary Statistics 
All analyses will use SAS® version 9.4 or higher. Summary tables will be organized by treatment group. 
All available data will be used in the analyses, and important data will be included in data listings, sorted 
by Stage 1 treatment group, patient, and by visit within patient.  
Unless otherwise noted, categorical data will be presented using counts and percentages, with the 
number of patients in the analysis population by treatment group as the denominator for percentages.

Percentages are rounded to one decimal place except 100% will be displayed without any decimal places 
and percentages will not be displayed for zero counts. Continuous data, unless otherwise noted, will be 
summarized using the number of observations (n), mean, standard deviation (SD), median, minimum, and 
maximum.  The mean and median will be rounded to 1 decimal place greater than the precision of the 
original value, up to a maximum of 3 decimal places. The SD will be rounded to 2 decimal places greater 
than the precision of the original value, up to a maximum of 3 decimal places.  
Supporting figures will be provided for some efficacy or safety analyses in addition to the summary tables.  
Efficacy listings will include analysis flags and/or imputed values to show which values were used in the 
summary tables.  In addition, analysis visits will be displayed in the listing if it is important for the 
corresponding summary. 
9.2 Hypothesis Testing and Multiplicity of Endpoints  
The primary efficacy endpoint is change from Baseline to Week 6 [Stage 1] and from Week 6 to Week 12 
[Stage 2] in the CMAI total score. For the primary efficacy endpoint, the null hypothesis is that there is no 
treatment effect in Stage 1 and Stage 2 and it will be tested against the alternative that there is a 
treatment effect in at least one of the 2 stages.   
A gate-keeping procedure will be used to control the overall type 1 error at 2-sided α = 0.05 for the 
primary and one key secondary (mADCS-CGIC-Agitation) efficacy comparisons. 
Specifically, the treatment comparison testing sequence is as below: 
1. CMAI total score – high dose vs. placebo 
2. mADCS-CGIC-Agitation – high dose vs. placebo 
3. CMAI total score – low dose vs. placebo 
4. mADCS-CGIC-Agitation – low dose vs. placebo 
For the remaining secondary efficacy endpoints, treatment comparisons will be performed at nominal 
significance level of 0.05. 
10.0 Efficacy Statistical Analysis Methods 
The study schematic in Figure 1 should be referenced to identify treatment groups that are described in 
the subsequent efficacy sections. 
10.1 Consideration of Primary Estimand and Sensitivity Analysis 
The purpose of this study is to assess the expected drug effect in a future population that results from 
patients initiating AVP-786 18 mg, AVP-786 28 mg versus Placebo. The estimand of primary interest is 
defined as follows:  
• 
Population: All patients who meet the inclusion/exclusion criteria, and who have at least 1 post 
baseline efficacy assessment (mITT). 
• 
Variable: Change from baseline to Week 6, Week 6 to 12 in the CMAI total score. 
• 
Intercurrent event(s): The “treatment policy” strategy will be followed, whereby the value for the 
variable of interest will be used regardless of adherence to randomized treatment and/or initiation 
of any concomitant medications which may include rescue medication (Lorazepam) and 
disallowed medications. 
• 
Population-level summary: The between-treatment difference in the mean changes from baseline 
to Week 6 (Stage 1) and change from Stage 2 baseline to Week 12 (Stage 2) in the CMAI total 
score. 
All data collected during the study treatment period will be used for statistical analysis. For the primary 
efficacy analysis, the treatment effect will be estimated using a likelihood-based mixed model repeated

28 
 
measures (MMRM) on observed data at each Stage separately. Under the MAR assumption, MMRM 
provides an unbiased estimate of treatment effect for the treatment period. Sensitivity analyses of the 
primary efficacy endpoint will be performed with missing values imputed by multiple imputation under 
MNAR (Section 10.4.3). In addition, missing value imputed by LOCF and WOCF+LOCF will also be 
performed. These sensitivity results in totality will be used to substantiate the credibility of the results. 
10.2 Derivation of Primary Efficacy Endpoints 
CMAI was assessed at Stage 1 - Baseline, Week 1, 2, 3, 6, and Stage 2 - Baseline (same as Stage 1 
Week 6), Week 3 (study Week 9) and 6 (study Week 12).  
Observed CMAI total scores including those from unscheduled visits and early discontinuation, are 
assigned analysis visit based on visit window Table 3-1 using assessment’s study days. If 2 or more visits 
occur within the same analysis window, then the values closest to the target day will be used.  If the 
assessment is the same distance from the target day, then the latest one will be used. After applying visit 
window, there is only one non-missing or missing value for each analysis visit. These data are called 
observed data and change from baseline in CMAI total score (observed data) for SPCD analysis are 
derived by subtracting corresponding baseline value at each stage and visit.  
Change from baseline in CMAI total score (observed data) for 12-Week Parallel Group analysis can be 
similarly derived by applying visit window in Table 3-5A and other efficacy endpoint derivation follow the 
same algorithm. 
10.3 Primary Efficacy:  SPCD Mixed Model Repeated Measures (MMRM) 
The primary efficacy endpoints (change from Baseline to Week 6 [Stage 1] and from Week 6 to Week 12 
[Stage 2] in the CMAI total score) will be analyzed using a weighted test statistic with the treatment 
effects in each Stage estimated by a likelihood-based mixed model repeated measures (MMRM) analysis 
(Chen et al., 2011).  This analysis will include observed data from all Stage 1 mITT patients and from 
Stage 2 data for Stage 1 Placebo Non-responder Subset.  Visit windows will be applied for unscheduled 
or early termination visits.  The null hypothesis to be tested is that there will be no difference in the 
change in CMAI total score between AVP-786 and placebo in Stage 1 and Stage 2 for each dose as 
specified in Section 9.2. 
Separate MMRMs will be used for Stage 1 and Stage 2. Stage 1 treatment effect will be estimated by the 
Week 6 treatment difference and the Stage 2 treatment effect will be estimated by the Week 12 treatment 
difference.  The model will include terms for treatment, visit, treatment-by-visit interaction, baseline CMAI 
total score, baseline-by-visit interaction, baseline NPI AA (≤ 6 vs. > 6), risk assessment for falls 
(normal/mild vs. moderate/severe), and concomitant use of antipsychotic medications (yes vs. no).  Stage 
2 baseline will be used for Stage 2 model. Unstructured covariance matrix will be used.  If there are 
convergence issues, then the following covariance structures other than the unstructured will be used in 
the order of 1) autoregressive of order 1 (AR1), 2) compound symmetry (CS) and the covariance structure 
converging to the best fit will be used as the primary analysis.   
The treatment effect estimates in each stage will be used to construct a combined weighted test statistic, 
𝑍𝑍𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀.  The formula is given below: 
𝑍𝑍𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 = 
𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡×(𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 1 𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒)+(1−𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡)×(𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 2 𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒)
ඥ(𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡)2×(𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 1 𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒)2+(1−𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡)2×(𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 2 𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒)2 
A weight of 0.6 will be used for Stage 1 and a weight of 0.4 for Stage 2.  The treatment effects and 
standard errors will be obtained directly from the model output.  The test statistic will be used to generate 
a 2-sided p-value for the hypothesis test.   
Model estimates (treatment difference and its 95% CI) will be reported for each stage however, only the 
overall p-value from the combined weighted test statistic will be provided. 
Treatment benefit is considered achieved if the CMAI total score shows statistically significant 
improvement.

10.4 Sensitivity Analyses for the Primary Efficacy Endpoints 
10.4.1 Seemingly Unrelated Regression (SUR) Method  
As an additional sensitivity analysis, a SUR analysis as described in Tamura and Huang (2007), will be 
run on the primary efficacy endpoint using the mITT population.  The SUR method is similar to the 
weighted test statistics method in that it will utilize data from all mITT patients in Stage 1 and the Placebo 
Non-responder Subset from the mITT in Stage 2.  Also, as with the primary analysis the models from 
Stage 1 and Stage 2 will be run separately and combined for an overall p-value.  LOCF within a stage will 
be used for missing values.  The SUR method takes into account the fact that random error from the two 
stages of the study may be correlated for patients with data in both stages. SAS PROC MODEL will be 
implemented for this analysis. 
Stage 1 and Stage 2 models will be included within the PROC MODEL statement using appropriate 
baseline and CFB values.  For patients who received AVP-786 in Stage 1 or who were placebo 
responders will have Stage 2 data set to missing.  The test statistic, 𝑍𝑍𝑠𝑠𝑠𝑠𝑠𝑠, is defined below: 
𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡× (𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 1 𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒) + (1 −𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡) × (𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 2 𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡𝑡 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒)
ඥ (𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡)2 × (𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 1 𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒)2 + 2 × (𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡) × (1 −𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡) × 𝐶𝐶𝐶𝐶𝐶𝐶(𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 1 𝑎𝑎𝑎𝑎𝑎𝑎 𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 2 𝑡𝑡𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟𝑟 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒) + (1 −𝑤𝑤𝑤𝑤𝑤𝑤𝑤𝑤ℎ𝑡𝑡)2 × (𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 2 𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒)2 
The weights will be the same as other models (0.6 in Stage 1 and 0.4 in Stage 2).  The test statistic will 
be used to generate a 2-sided p-value for the hypothesis test. 
10.4.2 Sensitivity Analysis with MNAR Using Multiple Imputation (MI)  
MMRM assumes data are MAR, which is a reasonable assumption in longitudinal clinical trials.  However, 
the possibility of missing not at random (MNAR) data can never be ruled out. In order to further evaluate 
robustness of the primary results to deviations from MAR assumptions, additional sensitivity analysis will 
be conducted. Sensitivity analyses based on selection model, pattern-mixture model, and/or shared 
parameter model will be performed in order to explore data missing mechanisms of MNAR and 
investigate the response profile of dropout reason. 
Pattern Mixture Models (PMM) based on MI with mixed missing data mechanisms will be used to 
investigate the response profile of dropout subjects by last dropout reason under MNAR mechanism for 
the following two scenarios: 
1) Dropout reasons due to AE as MNAR 
2) All dropouts as MNAR 
Delta Adjustment Imputation Methods 
This MNAR sensitivity analysis is to departure from MAR assumption by progressively increasing the 
delta until conclusion from the primary analysis is overturned. The delta is 0%, 5%, 10%, 15%,  .., 100% 
of the observed treatment difference in both stages between AVP-786 and Placebo from the primary 
analysis of MMRM model until conclusion of the primary analysis is overturned. When delta=0 the missing 
data are assumed to be MAR. When delta > 0, the missing data are assumed to be MNAR. 
1) Using Monte Carlo Markov Chain (MCMC) methodology from PROC MI to impute the intermittent 
missing data to a monotone missing pattern; 
2) Using a standard MAR-based multiple imputation approach from PROC MI to impute the 
monotone missingness data 
3) For subjects in the group treated with AVP-786 and with a dropout reason of AE, a delta will be 
added for all the values after the dropout time.  
4) Using MMRM model in the primary analysis to analyze the completed data using PROC MIXED 
on the multiple imputed data

5) Obtaining the overall results using PROC MIANALYZE.  
Placebo Based Imputation Methods 
Similar to “Standard” multiple imputations, except parameters for imputation model obtained from only the 
placebo (control) group. Missing data for both placebo and drug group are imputed based on the 
imputation model derived from placebo data within each stage. If drug improved outcomes prior to 
dropout, this benefit is carried into subsequent imputed values, but will diminish over time in accordance 
with the correlation structure. 
10.4.3 SPCD Ordinary Least Squares (OLS) ANCOVA  
As a sensitivity analysis, the change in CMAI total score will be analyzed using a weighted ordinary least 
squares (OLS) test statistics with treatment effect estimated by analysis of covariance (ANCOVA).  This 
analysis will include all mITT patients in Stage 1 and Placebo Non-responder Subset in Stage 2.   
As with the MMRM, separate ANCOVA models will be used for Stage 1 and Stage 2.  The model will 
include treatment, baseline NPI AA (≤ 6 vs. > 6), risk assessment for falls (normal/mild vs. 
moderate/severe), and concomitant use of antipsychotic medications (yes vs. no) as factors, and baseline 
CMAI total score as covariates.  The baseline CMAI total score for each stage is defined in Section 6.   
The treatment effect estimates in each stage will be combined in the same way as described for the 
primary efficacy analysis. 
Summary statistics including the change and percent change from baseline, model estimates (LS mean 
difference, 95% CI and p-value), and the standard effect size (SES) will be reported for each stage.  An 
overall p-value based on the weighted OLS z-statistic will be provided. 
The SES will be calculated using the following formula: 
𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 𝐶𝐶𝐶𝐶𝐶𝐶 𝐴𝐴𝐴𝐴𝐴𝐴−𝑀𝑀𝑀𝑀𝑀𝑀𝑀𝑀 𝐶𝐶𝐶𝐶𝐶𝐶 𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑃𝑏𝑏𝑜𝑜
𝑐𝑐ℎ𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎 𝑓𝑓𝑓𝑓𝑓𝑓𝑓𝑓 𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏𝑏 𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝𝑝 𝑆𝑆𝑆𝑆
 
Note that this analysis will also contain the result of the Stage 1 (CFB to Week 6) ANCOVA for the Stage 
1 mITT population. In addition, comparisons between placebo and each AVP-786 dose for the placebo 
non-responders only in Stage 2 (change from Week 6 to Week 12) will be available from this analysis.  
The above analysis will be carried out using below 2 missing value imputation methods (within stage):

LOCF – Missing values will be imputed by the last observation in each stage as described in 
Section 8.2 
• 
WOCF + LOCF – Missing values due to lack of efficacy will be imputed using the worst case 
value in each stage and missing values due to other reasons will be imputed by LOCF as 
described in Section 8.2 
10.4.4 SPCD Analysis on the ITT Population 
The primary endpoint will be analyzed using the ITT population, by the same method described in Section 
10.3. 
10.5 Secondary Efficacy Endpoint Analyses 
Continuous secondary efficacy endpoints described in Section 4.2.2 will be analyzed using the statistical 
methodologies described in the following sections.

Descriptive analyses of the GMHR variable will be provided at baseline (Screening visit) and Week 12. 
10.5.5 12-Week Parallel Group Analysis 
To evaluate the treatment effect under 12 weeks of exposure to the same treatment, a repeated 
measures analysis using observed data from all scheduled visits will be performed on the mITT 12-Week 
Parallel Group Population for all primary and secondary efficacy variables.

This analysis will compare treatment groups over time using a linear mixed effects repeated measure 
model which includes fixed effects for treatment, visit, treatment-by-visit interaction, baseline value, 
baseline-by-visit interaction, baseline NPI AA (≤ 6 vs. > 6), risk assessment for falls (normal/mild vs. 
moderate/severe), and baseline concomitant use of antipsychotic medications (yes vs. no).  For mADCS-
CGIC-Agitation, ADCS-CGIC-Overall, and PGIC, baseline CMAI total score will be used as the baseline 
value covariate. For mADCS-CGIC-Agitation and ADCS-CGIC-Overall, change relative to Baseline (Day 
1) will be used. The same selection of covariance matrix as the primary MMRM Section 10.0 (i.e., 
unstructured as first preference) will be employed. 
For the response (Section 10.5.3) analyses, a GEE model will also be performed with the same effects 
used in the MMRM model. 
10.6 Subgroup Analyses 
The primary efficacy endpoint will be analyzed for the below subgroups to evaluate potential differential 
treatment effect under 6 and 12 weeks treatment exposure.

10.6.3 Subgroup Patients Who Did Not Use Antipsychotics at Baseline 
This subgroup patient must meet protocol inclusion requirement for CGIS-Agitation score of ≥ 4 and did 
not use antipsychotics at baseline.  
The primary efficacy analysis will be performed using this subgroup.  Analyses will also be done on the 
mITT 12-Week Parallel Group populations. 
10.6.4 Additional Subgroups 
Additional analyses of subgroups, such as age group, sex, and baseline stratification factors, may be 
performed for the primary efficacy endpoint if deemed important and sample size permits.  
11.0 Safety Statistical Analysis Methods 
Safety will be assessed through the analysis of AEs, clinical laboratory assessments, ECGs, vital signs, 
physical and neurological examinations, S-STS, MMSE, TUG test, and ESS.  All safety analyses will be 
completed on the Safety population. 
Unless otherwise specified, safety analyses that include summaries of number and percentage (e.g., 
AEs) will be displayed using the following treatment groups: 
1. Placebo/Placebo: patients who were randomized to Placebo/Placebo, receiving placebo for the 
entire duration of the study (treatment segments D and G from the study schematic, including 
data from treatment segment A1 during Stage 1). A=A1 + A2, which are Stage 1 data for patients 
who were randomized to Placebo/Placebo and Placebo/AVP-786, respectively. Note that patients 
randomized to Placebo/AVP-786 (A2) but dropped out in Stage 1 (part of A2) are not included in 
this population. Instead, their data will be summarized under the ‘All Placebo’ treatment group. 
2. AVP-786 28/28 mg: patients receiving AVP-786 28 mg for the entire duration of the study (B and 
J). 
3. AVP-786 18/18 mg: patients receiving AVP-786 18 mg for the entire duration of the study (C and 
K). 
4. Placebo/AVP-786 28 mg: patients who switched from placebo to AVP-786 28 mg including those 
who received placebo and dropped out in Stage 1. This group will be further divided into data that 
occurred on placebo (A) and data that occurred on AVP-786 28 mg (E and H). 
5. Placebo/AVP-786 18 mg: patients who switched from placebo to AVP-786 18 mg including those 
who received placebo and dropped out in Stage 1. This group will be further divided into data that 
occurred on placebo (A) and data that occurred on AVP-786 18 mg (F and I).

6. All Placebo: This includes data from the Stages when patients who received placebo (A, D, and 
G). 
7. All AVP-786 28 mg: This includes data from the Stages when patients who received AVP-786 28 
mg (B, J, E, and H). 
8. All AVP-786 18 mg: This includes data from the Stages when patients who received AVP-786 18 
mg (C, K, F, and I). 
Placebo/Placebo, AVP-786 18/18 mg and AVP-786 28/28 mg treatment groups summarize the safety 
information for the Safety 12-Week Parallel Group population, which receive 12 week treatment 
exposure. It is what would be summarized if the study had been a 12 week parallel group design, and a 
conventional statistical test to compare these two groups can be performed if needed. 
 
All Placebo, All AVP-786 18 mg, and All AVP-786 28 mg treatment groups summarize the safety 
information for their corresponding treatment group under 6 week or 12 week treatment exposure in either 
Stage 1, Stage 2, or both. 
 
For quantitative summaries (e.g., ECGs, labs), the All Placebo and All AVP-786 groups will not be 
included. 
11.1 Adverse Events 
AE tables (except the AE Overview table) will only include summaries of TEAEs. Treatment-emergent 
adverse events are defined as AEs which first occur, or worsen, after the first dose of study medication 
and within 30 days after the permanent discontinuation of the study medication (i.e., first dose date ≤ AE 
start date ≤ last dose date + 30 days). 
An overview table containing the number and percentage of the following will be included: 
• 
Number of total AEs, TEAEs and deaths 
• 
Incidence of patients with at least one TEAE, drug-related TEAE, non-serious, serious adverse 
events (SAEs), drug-related serious adverse event, and death 
• 
Incidence of patients who discontinued due to TEAE, drug-related TEAE, SAE and drug-related 
SAE 
• 
Incidence of deaths and deaths due to drug-related TEAE 
TEAEs will be summarized by system organ class (SOC) and preferred term (PT), descending frequency 
of PT, and by maximum severity. Summaries of PTs will also be done for those occurring in at least 5% of 
patients in any treatment or study stage. 
AEs leading to discontinuation will be summarized by SOC and PT. Drug-related AEs will be summarized 
by SOC and PT and in descending frequency of PT. 
Time to onset for common TEAEs (as defined below) will be summarized descriptively for each of these 
events. In addition, summary stats for the duration and percentage of total study days will be provided for 
each AE. The n (%) of patients with recurrences will also be given. 
SAEs will be summarized by SOC and PT and will include a summary of drug-related events. 
Below are the rules to follow for AE summaries: 
• 
For patients who took AVP-786 28/28 mg, AVP-786 18/18 mg or Placebo/Placebo: If a patient 
has multiple AEs within the same SOC or PT, the patient will only be counted once within a level 
of MedDRA.

Effective Date: 16-Nov-2018/Version 3.0 
36 
 
• 
For patients who switched from placebo to AVP-786: If the same AE starts in both study stages, it 
should be counted under both placebo and AVP-786. 
• 
A drug-related AE is defined as an AE with an assigned relationship of “possibly related,” 
“related,” or missing. 
• 
When assessing severity, if a patient has 2 or more TEAEs within a study stage, the TEAE with 
the worst severity will be chosen. AEs with missing severity will be excluded from summaries of 
AE by severity. 
• 
A common TEAE is defined as a TEAE with an incidence of ≥3% in the All AVP-786 treatment 
group AND ≥2 times the incidence of the All Placebo treatment group. 
• 
Time to onset will be calculated in days as (AE start date – first dose date).  For patients who 
switched from placebo to AVP-786, the following rules will apply: 
o 
If an AE occurs when the patient is on AVP-786, time to onset is calculated as (AE start 
date – re-randomization date). This includes the time on AVP-786 only. 
o 
If the same AE occurs while the patient is on placebo and then again when the patient is 
on AVP-786, the AE will be counted in both groups, and first dose date will be defined as 
the first dose of placebo or first dose of AVP-786, depending on which treatment the 
patient was on when the AE occurred. 
• 
Duration of AE is generally defined as (AE end date – AE start date + 1). Duration will be 
calculated for placebo and AVP-786 separately. Below are some additional considerations for AE 
duration: 
o 
If the patient has an AE on placebo that has not ended when the patient takes the last 
dose of placebo (either due to switching to AVP-786 or end of study), AE end date is 
defined as the last dose date of placebo. 
o 
If the patient has an AE on AVP-786 that has not ended when the patient ends the study, 
AE end date is defined as the last dose date of study drug. 
o 
If the same AE occurs more than once while the patient is on the same treatment, total 
duration will be the sum of the individual AE durations. 
• 
For a given patient, percentage of total study days is defined as total duration (as defined above) 
divided by (last dose date – first dose date + 1) x 100. 
• 
Recurrence is defined as a new report of the same TEAE with a new AE start date within a given 
treatment (e.g. an AE that occurs for a patient on placebo and then again on AVP-786 will not be 
considered a recurrent event). 
AEs will be coded using MedDRA version 18.1. 
11.2 Clinical Laboratory Assessments 
Clinical labs will be reported for hematology, chemistry and urinalysis. Labs are collected at Screening, 
Week 3, Week 6, Week 9, and Week 12. The following parameters will be summarized descriptively 
through change from baseline and percent change from baseline by treatment, visit for both Safety 
Population and Safety 12-Week Parallel Group Population.

• 
Thyroid function tests: (thyroid stimulating hormone [TSH], and reflex T3 and T4 if TSH is 
abnormal).  Thyroid function tests are collected at the Screening visit only and will only be 
provided in a data listing. 
Out-of-range values will be assessed through shift tables. Each lab value will be assessed as low, normal 
or high based on the normal ranges provided by the central lab. Frequencies of each combination of 
shifts will be provided by treatment group.  
Shift tables will be created by stage and for the Stage 1 Placebo, AVP-786 28 mg, and AVP-786 18 mg; 
Stage 2 Placebo (Stage 1 Placebo re-randomized to Placebo), Stage 2 AVP-786 28 mg (Stage 1 Placebo 
re-randomized to AVP-786 28 mg), and Stage 2 AVP-786 18 mg (Stage 1 Placebo re-randomized to 
AVP-786 18 mg). In Stage 1, AVP-786 will be compared to placebo and in Stage 2, the placebo patients 
who were re-randomized to either AVP-786 or placebo will be compared. Baseline in all shift tables is the 
last assessment prior to first dose in each stage. Shift tables will also be created for Placebo/Placebo, 
AVP-786 28/28 mg and AVP-786 18/18 mg for the Safety 12-Week Parallel Group population. 
Potentially clinically significant (PCS) tables will also be used to summarize out-of-range values. PCS 
values are found in Table 4. The number and percentage of patients meeting the criteria below will be 
summarized by treatment group. Summaries will be given for any time post-baseline. The denominator for 
the percentages will be the number of patients who had a post-baseline assessment for each parameter.

Over the course of the study, there may be some lab tests performed that are not mentioned in the 
protocol. These tests will not be summarized but will be included in the listings and flagged as 
non-protocol tests. 
11.3 ECGs 
ECGs will be assessed by a central reader and will be recorded at the following visits: 
• 
Screening (performed in triplicate) 
• 
Baseline (pre-dose) 
• 
Baseline (2-3 hours post-dose) 
• 
Week 2 
• 
Week 3 
• 
Week 6 (pre-dose) 
• 
Week 6 (2-3 hours post-dose) 
• 
Week 9 
• 
Week 12 
The following quantitative parameters will be reported by the central reader: heart rate, PR interval, QRS 
duration, QT interval (uncorrected), and QT interval due to Fridericia’s correction (QTcF).  Change from 
baseline and percent change from baseline will be calculated for each parameter and summarized by the 
treatment groups mentioned in Section 11.  Note that for patients who switched from placebo to one of 
the AVP-786 doses, baseline is defined as described in Section 6. 
In addition, since ECGs are recorded pre- and post-dose at Baseline and Week 6, change from pre- to 
post-dose will be summarized at these visits.

PR interval and QTcF will be further investigated through PCS tables, for which the criteria are found in 
Table 5 below.  The number and percentage of patients meeting the criteria below will be summarized by 
treatment group.  Summaries will be given for both overall (i.e., any time post-baseline) and by visit.  For 
QTcF, males and females will be assessed separately.  Patients will be included in all categories for 
which they qualify.  For criteria on the “Actual” values, the denominator for the percentages is the number 
of patients who had a post-baseline assessment for each parameter.  For criteria on the change, the 
denominator is the number of patients who had a baseline and post-baseline assessment.

ECG overall interpretations will be summarized by the number and percentage that were normal or 
abnormal.  The interpretations by the cardiologist (i.e., central ECG) will be used for these summaries. 
The listings will provide all interpretations and corresponding details. 
11.4 Vital Signs 
Vital signs will be assessed at all visits.  Starting with Protocol Amendment #3, orthostatic blood pressure 
and heart rate measurements will be performed at all clinic visits.  Supine blood pressure and heart rate 
will be measured twice.  The average of the measurements will be presented.  Additionally, a single 
measurement of standing will be collected.  The following parameters will be summarized: systolic blood 
pressure (SBP), diastolic blood pressure (DBP), heart rate, respiratory rate, and temperature. These 
parameters will be summarized through change from baseline and percent change from baseline in 
similar fashion as the ECG parameters.  
Vital signs will also be assessed through PCS criteria, which are given in Table 6. Patients will be counted 
if they meet the criteria below at any time post-baseline. The definition of baseline is consistent with those 
for ECG parameters. The denominators are the number of patients with both a baseline and 
post-baseline assessment.

Orthostatic changes in blood pressure and heart rate from supine to standing will also be summarized.  
Additionally, patients meeting orthostatic hypotension or postural tachycardia PCS criteria at any time 
post-baseline will be summarized according to the criteria in Table 7.

11.5 Physical and Neurological Examinations 
Physical and neurological examinations will be performed at Screening, Week 6, and Week 12 and 
include assessments of the head, eyes, ears, nose, throat, lymph nodes, skin extremities, respiratory, 
gastrointestinal, musculoskeletal, cardiovascular, and nervous systems.  Physical and neurological 
examination data will be provided in a data listing. 
11.6 Sheehan Suicidality Tracking Scale (S-STS) 
The S-STS is a prospective scale that assesses treatment-emergent suicidal thoughts and behaviors.  
Each item of the S-STS is scored on a 5-point Likert scale as shown below: 
S-STS Item Scale 
• 
0 = Not at all 
• 
1 = A little 
• 
2 = Moderate 
• 
3 = Very 
• 
4 = Extremely 
The S-STS can be analyzed as individual item scores, suicidal ideation subscale score, suicidal behavior 
subscale score, and a total score.  For the screening visit, the timeframe for the items 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 all clinic visits.  Scores, CFB in scores, and percent CFB in scores will be 
summarized descriptively by visit and treatment group for each subscale and total score. S-STS suicidal 
ideation subscale score, suicidal behavior subscale score, and a total score will be calculated as follow:

11.7 Mini Mental State Examination (MMSE) 
The MMSE is a brief 30-point questionnaire test that is used to screen for cognitive impairment and 
severity of cognitive impairment.  The MMSE scale comprises 11 questions or simple tasks concerning 
orientation, memory, attention, and language to evaluate a patient’s cognitive state and are scored 
according to the following ranges:   
Item

The total score is calculated by summing all of the item scores and ranges from 0 to 30.  Higher scores 
indicate milder cognitive impairment. 
The MMSE will be assessed at Screening, Baseline, Week 6, and Week 12.  The MMSE total score, CFB 
in total score, and percent CFB in total score will be summarized descriptively by visit and treatment 
group. 
11.8 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. 
The TUG test will be performed at Screening, Week 6, and Week 12.  The TUG time, CFB in TUG time, 
and percent CFB in TUG time will be summarized descriptively by visit and treatment group. 
11.9 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.  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, Week 6, and Week 12.  The total score, CFB in total score, and 
percent CFB in total will be summarized descriptively by visit and treatment group. 
12.0 Additional Summaries 
12.1 Patient Disposition

In addition, below information will be summarized by Stage 1 randomized treatment group unless 
specified otherwise. 
• 
Baseline disease characteristics: Safety Population, caregiver relationship to patient, patient living 
arrangement,   
• 
Randomization Stratification factors: mITT population, Baseline NPI AA domain score (≤ 6 and > 
6), Risk for falls (normal/mild and moderate/severe), Use of concomitant antipsychotic 
medications (yes/no). 
• 
Percent of Responders and Non-Responders at Week 6: mITT Population 
• 
Stage 1 baseline efficacy assessment: mITT population, for CMAI, NPI, CGIS-Agitation  
• 
Stage 2 Baseline Efficacy Assessments - Stage 1 Placebo Non-Responders: Stage 2 mITT 
Population and treatment groups, for CMAI, NPI, CGIS-Agitation 
 
For categorical parameters, the denominators for the percentages are the number of patients who had 
the parameter assessed. 
12.4 Medical History 
Medical history will be summarized for the Safety populations by SOC and PT based on the Stage 1 
randomization and will be provided in data listings. 
12.5 Exposure 
Duration of exposure will be summarized quantitatively for the Safety population using the number of 
days on study medication for each patient, displayed by treatment group. Summaries will be done for 
Placebo/Placebo, AVP-786 28/28 mg, AVP-786-18/18 mg, and each arm of the Placebo/AVP-786 18 mg, 
Placebo/AVP-786 28 mg groups. Duration for the Placebo/Placebo and AVP-786 28/28 mg, AVP-786 
18/18 mg groups will be calculated as (last dose date – first dose date + 1). For Stage 1 Placebo/AVP-
786 28 mg, Placebo/AVP-786 18 mg (placebo portion), duration will be calculated from first dose until the 
day prior to re-randomization, i.e. (re-randomization date – first dose date). For Stage 2 (AVP-786 
portion), duration will be calculated from re-randomization to last dose date, i.e., (last dose date – re-
randomization date + 1). 
An additional summary of exposure will be provided by dose taken for patients who took AVP-786 at any 
time during the study. The number of days at the specified dose level will be summarized. Treatment 
groups will be AVP-786/AVP-786 and Placebo/AVP-786 groups. Since the dosing regimen increases 
after one week on treatment but a visit does not occur for two weeks after starting treatment, it is

assumed that each dose level is taken for 7 days, as specified in the protocol. Doses summarized will be 
18 mg QD, 18 mg BID, and 28 mg BID. Dosing regimen can be found in Figure 1. 
12.6 Compliance 
Overall treatment compliance will be calculated as a percentage using the total number of capsules that 
were taken.  Patients will be grouped into categories of <80%, 80% to 120%, >120%. Counts will be 
summed over the visits for each patient to calculate an overall compliance value. 
Compliance will be summarized for the Safety population as described above and using descriptive 
statistics for Placebo/Placebo, AVP-786 28/28 mg, AVP-786 18/18 mg, and each arm of the 
Placebo/AVP-786 groups.  The number of doses taken and number of doses should have taken are 
necessary to calculate compliance.  The calculation for number of doses should have taken will be slightly 
different for subjects who were randomized vs. those who were not re-randomized, as well as between 
Stage 1 and Stage 2.  These differences are provided in the table below.  The 3 steps for calculating 
compliance are shown here: 
1. Doses taken = actual amount taken 
2. Doses should have taken:  
Stage 
Patients re-randomized 
Patients not re-randomized 
Stage 1 
2 * (last dose date Stage 1 – first dose 
date Stage 1) + 1 
2 * (last dose date Stage 1 – first dose 
date Stage 1) + 1 
Stage 2 
2 * (last dose date Stage 2 – first dose 
date Stage 2) +1 
2 * (last dose date Stage 2 – first dose 
date Stage 2) +1 
Overall 
2 * (last dose date Stage 2 – first dose 
date Stage 1) + 1 
2 * (last dose date Stage 2 – first dose 
date Stage 1) + 1 
 
3. Compliance = (doses taken / doses should have taken) * 100 
 
For the calculations in the above table, the formulas are based on the assumption that patients take 2 
capsules per day except for the last day, in which they only take 1.  One exception is for the Stage 1 
calculation of patients who were re-randomized. For these patients, 1 is not subtracted because they will 
take 2 capsules on the last day of Stage 1. 
12.7 Prior and Concomitant Medications, Non-drug Therapies and Interventions 
The number and percentage of prior and concomitant medications will be provided by the treatment 
groups used for the safety analyses.  Summaries will be provided by anatomical therapeutic chemical 
(ATC) and preferred term for the Safety population.  Non-drug therapies and nonpharmacological 
interventions will be only provided in data listings. 
In addition, below information will be summarized;  
• 
At baseline, number and % patients who used medications for AD (donepezil, rivastigmine, 
galantamine, memantine), medications/medication classification  for agitation secondary to AD 
(atypical antipsychotics, antidepressants, butyrophenones, buspirone).  
• 
Cumulative number and % patients who used short term rescue medication lorazepam by visit. 
12.8 Pharmacokinetics and Pharmacodynamics 
Plasma concentrations for d6-DM, d6-DM metabolites, and Q will be collected at Week 6 and Week 12.  
Plasma concentration will be summarized by visit and treatment group for the Safety population overall 
.  Additionally, PK/PD correlations 
will be provided.
