Mini-Mental Scale Evaluation, 2nd Edition (MMSE-2) Score (Exploratory)	Day 210	Change from Baseline from MMSE-2 Score through 210 days (MMSE-2 Score ranges from 0 to 30; a lower score indicates severe dementia; a higher score indicates better cognitive function; 0 to 10 = late stage dementia or severe cognitive impairment, 30 = normal)
Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-COG) (Exploratory)	Day 210	Change from Baseline in ADAS-COG Score through 210 days (ADAS-COG Score ranges from 0 to 70; a lower score indicates better cognitive function; a higher score indicates greater dysfunction; 0 to 10 = minimal to no cognitive impairment, 31 to 70 = severe cognitive impairment)
Alzheimer's Disease Cooperative Study-ADL scale (ADCS-ADL) (Exploratory)	Day 210	Change from Baseline in ADCS-ADL Score through 210 days (ADCS-ADL Score ranges from 0 to 78; a lower score indicates greater severity; a higher score indicates better functioning in daily activities; 0 to 20 = severe impairment, 61 to 78 = minimal impairment)
Clinical Global Impressions - Improvement (CGI-I) (Exploratory)	Day 210	Change from Baseline in CGI-I Score through 210 days (CGI-I Score ranges from 1 to 7; a lower score indicates the patient has improved; a higher score indicates the patient is very much worse since Baseline; 1 = very much improved, 7 = very much worse since Baseline)
Clinical Global Impressions - Severity (CGI-S) (Exploratory)	Day 210	Change from Baseline in CGI-S Score through 210 days (CGI-S Score ranges from 1 to 7; a lower score indicates the patient is less severely ill; a higher score indicates among the most extremely ill patients; 1 = normal, not at all ill, 7 = among the most extremely ill patients)
Treatment-emergent adverse events (TEAEs)	Day 210	Incidence of TEAEs through Day 210
Serious Adverse Events (SAEs)	Day 210	Incidence of SAEs from informed consent through Day 210
Adverse Events (AEs)	Day 210	Incidence of AEs from informed consent through Day 210
Clinical Dementia Rating - Global Score	Day 210	CDR - Global Score: To estimate the magnitude and variability of clinical response to a drug combination Tablet in patients with Alzheimer's disease (AD) after 180 days of treatment against Placebo Tablet.; The CDR scale is a widely used dementia staging instrument that produces a global score. This study will use global score for estimation, comparisons and analysis. The global score ranges from 0 to 3. The sites are instructed to use a standardized online calculator for scoring. This resulting calculation reflects the following scoring 0 = normal, no cognitive impairment; 0.5 = very mild dementia, minimal impairment in one domain; 1 = mild dementia, noticeable impairment in one or more domains; 2 = moderate dementia, significant impairment in multiple domains; 3 = severe dementia, major impairment in multiple domains.
Clinical Dementia Rating - Sum of Boxes (CDR-SB) Score	Day 210	CDR - SB: To estimate the magnitude and variability of clinical response to a drug combination Tablet in patients with Alzheimer's disease (AD) after 180 days of treatment against Placebo Tablet. The CDR scale is a widely used dementia staging instrument that produces a summated score (sum of boxes score). This study will use the summated score, comparisons and analysis. The "Sum of boxes" scoring methodology sums the score for each of the 6 domains and provides a value ranging from 0 to 18 that can change in of 0.5 or greater. Higher scores indicate greater disease severity. A positive change from baseline indicates clinical decline. Score Range from 0 to 18. Response choices are 0 = normal; 0.5 to 2.5 = questionable impairment; 3.0 to 4.0 = very mild dementia; 4.5 to 9.0 = mild dementia; 9.5 to 15.5 = moderate dementia; 16.0 to 18.0 = severe dementia.
Mini-Mental Scale Evaluation, 2nd Edition (MMSE-2) Score	Day 210	MMSE-2: To estimate the magnitude and variability of clinical response to a drug combination Tablet in patients with Alzheimer's disease (AD) after 180 days of treatment against Placebo Tablet. The MMSE-2 is a widely used test of cognitive function among the elderly. The Standard Version consists of a 30-point questionnaire that includes tests of orientation, attention, memory, language, and visual-spatial skills. Score Range from 0 to 30. Response choices are 30 = normal; 26 to 29 = mild cognitive impairment; 21 to 25 = early stage dementia or mild cognitive impairment; 11 to 20 = middle stage dementia or moderate cognitive impairment; 0 to 10 = late stage dementia or severe cognitive impairment.
Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-COG)	Day 210	ADAS-COG: To estimate the magnitude and variability of clinical response to a drug combination Tablet in patients with Alzheimer's disease (AD) after 180 days of treatment against Placebo Tablet. The ADAS-COG is used to assess cognitive symptoms of dementia. It consists of 7 performance items and 4 clinician-rated items assessing memory, orientation, language and praxis. Score Range from 0 to 70. Response choices are 0 to 10 = minimal to no cognitive impairment; 11 to 20 = mild cognitive impairment; 21 to 30 = moderate cognitive impairment; 31 to 70 = severe cognitive impairment.
Alzheimer's Disease Cooperative Study-ADL scale (ADCS-ADL)	Day 210	ADCS-ADL: To estimate the magnitude and variability of clinical response to a drug combination Tablet in patients with Alzheimer's disease (AD) after 180 days of treatment against Placebo Tablet. The ADCS-ADL is a comprehensive battery of ADL questions used to measure the functional capabilities of patients; each item is rated from the highest level of independent performance to complete loss. Score Range from 0 to 78. Response choices are 0 to 20 = severe impairment; 21 to 40 = moderate impairment; 41 to 60 = mild impairment; 61 to 78 = minimal impairment.
Clinical Global Impressions - Improvement (CGI-I)	Day 210	CGI-I: To estimate the magnitude and variability of clinical response to a drug combination Tablet in patients with Alzheimer's disease (AD) after 180 days of treatment against Placebo Tablet. The Clinical Global Impressions-Improvement (CGI-I) scale will be assessed at all visits after Baseline. The Investigator (or designee) will answer the following question: "Compared to the patient's condition at Baseline. Score Range from 1 to 7. Response choices are: 1 = very much improved; 2 = much improved; 3 = minimally improved; 4 = no change from Baseline; 5 = minimally worse; 6 = much worse; 7 = very much worse since Baseline".
Clinical Global Impressions - Severity (CGI-S)	Day 210	CGI-S: To estimate the magnitude and variability of clinical response to a drug combination Tablet in patients with Alzheimer's disease (AD) after 180 days of treatment against Placebo Tablet. The Clinical Global Impressions-Severity (CGI-S) scale will be assessed at Baseline and all visits afterward. The Investigator (or designee) will answer the following question: "Considering your total clinical experience with AD, how ill is the patient at this time?" Score Range from 1 to 7. Response choices are 1 = normal, not at all ill; 2 = borderline ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill patients.
