What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Treatment-emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)	An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. SAE: an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study medication and up to 6 months after last dose (up to 18 months) that were absent before treatment or worsened relative to pre-treatment state. AEs included both serious and non-serious adverse events.	Day 1 up to 6 months after last dose of study medication (up to 18 months)
Number of Participants With Change From Baseline in Brain Magnetic Resonance Imaging (MRI) Abnormalities	Number of participants with new clinical findings not evident on the baseline scans, such as brain edema, hemorrhage, encephalitis and other pathology (cerebral edema, cerebral/meningeal enhancement, micro hemorrhage, parenchymal hematoma, subarachnoid hemorrhage, subdural hematoma, cortical infarcts, subcortical grey matter infarcts, white matter infarcts and white matter hyper intensities) were assessed from structural magnetic resonance imaging (MRI). Participants with brain abnormality other than those listed above assessed using MRI scan were reported under 'other' category. Only those MRI findings in which at least 1 participant had event, were reported.	Baseline up to Month 18
Number of Participants With Gadolinium Use in Brain Magnetic Resonance Imaging (MRI)	Brain MRI included gadolinium contrast if investigator determined this was necessary for participant care either based on clinical signs or the non-contrast MRI. This decision was made by the investigator on the basis of change in the clinical examination or in response to a possible abnormality seen on the non-contrast brain MRI.	Baseline up to Month 18
Change From Baseline in Amyloid Load at Month 13 Using Positron Emission Tomography (PET) Technique: Cohort M	Quantitative amyloid imaging was performed using PET technique using [11C] Pittsburgh Compound B (PIB) for following brain areas: frontal, temporal, parietal and occipital cortices, anterior and posterior cingular cortex, cerebellum, pons, and subcortical white matter. For target regions of interest, beta-amyloid plaque imaging radiotracer (PIB) retention data was expressed as standard uptake value ratio (SUVR) which was defined as a ratio of radioactivity uptake of the target region relative to the cerebellum reference region. This outcome measure was planned to be analyzed only for cohort M.	Baseline, Month 13

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-cog) Total Score at Months 3, 6, 9, 13 and 18	ADAS-cog is a structured scale assessing the severity of cognitive impairment in Alzheimer's Disease. It comprises of following 11 items (range): word recall (0-10), naming objects and fingers (0-5), following commands (0-5), constructional praxis (0-5), ideational praxis (0-5), orientation (0-8), word recognition (0-12), recall of test instructions (0-5), spoken language ability (0-5), word-finding difficulty (0-5), comprehension of spoken language (0-5). The total score was calculated as the sum of the scores for the 11 items. ADAS-cog total score ranges from 0 (no impairment) to 70 (maximum impairment). Higher total and individual item scores indicate greater cognitive impairment.	Baseline, Month 3, 6, 9, 13, 18
Change From Baseline in Disability Assessment for Dementia (DAD) Total Score at Month 6, 13 and 18	DAD is a functional assessment based on interview with the caregiver of participants. It consists of 40 items, 17 related to self-care and 23 items involving instrumental activities of daily living. Each item scored as yes = 1, no = 0 and not applicable= N/A. A total score is obtained by adding the rating for each question and converting this to a total score out of 100. The items rated N/A are not considered for the total score. DAD total score range from 0 (more dysfunction) to 100 (better function), with higher scores indicating better functioning.	Baseline, Month 6, 13, 18
Change From Baseline in Mini-Mental State Examination (MMSE) Total Score at Month 13	Mini-Mental State Examination (MMSE) measured general cognitive functioning: orientation, memory, attention, concentration, naming, repetition, comprehension, and ability to create a sentence and to copy two intersecting polygons. Total MMSE score ranged from 0 (worst cognitive state) to 30 (best cognitive state), where higher score indicates better cognitive state.	Baseline, Month 13
