Trial Title: Efficacy, Safety and Tolerability of AVP-786 for the Treatment of Agitation in Patients With Dementia of the Alzheimer's Type

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: PHASE3
- Number of Arms: 8.0

Eligibility Criteria:
Inclusion Criteria:~* Diagnosis of probable Alzheimer's Disease (AD) according to the 2011 National Institute on Aging-Alzheimer's Association (NIA-AA) working groups criteria~* The participant has clinically significant, moderate/severe agitation at the time of screening and for at least 2 weeks prior to randomization~* The diagnosis of agitation must meet the International Psychogeriatric Association (IPA) provisional definition of agitation~* Either out patients or residents of an assisted-living facility or a skilled nursing home~* Clinical Global Impression of Severity of Illness (CGIS) score assessing Agitation is \>= 4 (moderately ill) at screening and baseline~* Mini-Mental State Examination (MMSE) score is between 6 and 26 (inclusive) at screening and baseline~* Caregiver who is able and willing to comply with all required study procedures. In order to qualify as a reliable informant (i.e., caregiver) capable of assessing changes in participant's condition during the study, the individual must spend a minimum of 2 hours per day for 4 days per week with the participant.~Exclusion Criteria:~* Participant has dementia predominantly of non-Alzheimer's type (e.g., vascular dementia, frontotemporal dementia, Parkinson's disease, substance-induced dementia)~* Participants with co-existent clinically significant or unstable systemic diseases that could confound the interpretation of the safety results of the study (e.g., malignancy, poorly controlled diabetes, poorly controlled hypertension, unstable pulmonary, renal or hepatic disease, unstable ischemic cardiac disease, dilated cardiomyopathy, or unstable valvular heart disease)~* Participant with myasthenia gravis

Study Arms:
- Stage 1: Placebo (Type: PLACEBO_COMPARATOR): 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.
- Stage 1: AVP-786-18 (d6-DM 18 mg/Q 4.9 mg) (Type: EXPERIMENTAL): 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.
- Stage 1: AVP-786-28 (d6-DM 28 mg/Q 4.9 mg) (Type: EXPERIMENTAL): 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.
- Stage 2: Placebo (Type: PLACEBO_COMPARATOR): 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.
- Stage 1: AVP-786-18 (d6-DM 18 mg/Q 4.9 mg) to: Stage 2: AVP-786-18 (d6-DM 18 mg/Q 4.9 mg) (Type: EXPERIMENTAL): 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..
- Stage 1: AVP-786-28 (d6-DM 28 mg/Q 4.9 mg) to Stage 2: AVP-786-28 (d6-DM 28 mg/Q 4.9 mg) (Type: EXPERIMENTAL): 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
- Experimental: Stage 1: Placebo to: Stage 2: AVP-786-18 d6-DM 18 mg/Q 4.9 mg (Type: EXPERIMENTAL): 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.
- Stage 1: Placebo to: Stage 2: AVP-786-28 d6 DM 28 mg/Q 4.9 mg (Type: EXPERIMENTAL): 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.
