An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the 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 drug and up to 30 days after Week 25 dose that were absent before treatment or that worsened relative to pretreatment state.

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 the 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 dose of study medication and up to 52 weeks after the dose that were absent before treatment or that worsened relative to pre-treatment state.

Physical examination included the assessment of abdomen, back/spinal, breasts, external genitalia, extremities, general appearance, head, eyes, ears, nose, throat (HEENT), heart, lungs, lymph nodes and skin.

Criteria for determining potentially clinically important (PCI) vital signs was described as: supine blood pressure (BP)- systolic (greater than or equal to \[\>=\]160 millimeter mercury \[mm Hg\] or less than or equal to \[\<=\]90 mm Hg and increase or decrease of \>=20 mm Hg compared to baseline value), supine diastolic BP (\>=100 mm Hg or \<= 50 mm Hg and increase or decrease of \>=15 mm Hg compared to baseline value), supine pulse rate (\>=120 beats per minute (bpm) or \<=45 bpm and increase or decrease of \>15 bpm compared to baseline value), body temperature (\>38.3 degree Celsius and \<35 degree Celsius).

Criteria for determining PCI ECG result was described as: heart rate (\>=120 bpm or \<=45 bpm and increase or decrease of \>15 bpm compared to baseline value), PR interval (\>=220 millisecond (msec) and change of \>=20 msec compared to baseline value), QRS interval (\>=120 msec), corrected QT (QTc) interval for men (\>450 msec), QTc interval for women (\>470 msec).

Criteria for PCI laboratory results: hematology (hematocrit \[decrease \>=5%\], hemoglobin \[decrease \>=20gram/liter {g/L}\] from baseline, white blood cells \[\<3\], neutrophils \[\<1.5\], platelet \[\<100\], eosinophils \[\>0.5\] \*10\^9/L); blood chemistry (sodium \[\>5\], potassium \[\>0.5\], fasting glucose \[\>0.83\], phosphorous \[\>0.162\] millimole/L \[mmol/L\] above upper limit of normal \[ULN\] and below lower limit of normal \[LLN\], non-fasting glucose \>5 mmol/L above ULN, \>0.56 mmol/L below LLN, creatinine \>1.36\*ULN, blood urea nitrogen \>1.5\*ULN, calcium \[change of \>=0.25 mmol/L\], total protein \[change of \>=20g/L\], albumin \[change of \>=10g/L\], uric acid \[change of \>0.119mmol/L\] from baseline and outside normal limits); Liver function tests (alanine aminotransferase/serum glutamic pyruvic transaminase \[ALT/SGPT\] and aspartate aminotransferase/serum glutamic oxaloacetic transaminase \[AST/SGOT\] \>2\*ULN, total bilirubin \>2\*ULN, alkaline phosphatase \>1.5\*ULN, gamma-glutamyl-transpeptidase \[GGT\] \>3\*ULN).

Neurological examination included the assessment of mental status, cranial nerves, visual fields, sensory, motor, gait, primitive reflexes and tendon reflexes.

MMSE measures general cognitive functioning: orientation to time (range: 0 to 5) and orientation to place (range: 0 to 5), registration of 3 words (range: 0 to 3), attention and calculation (range: 0 to 5), recall of 3 words (range: 0 to 3), naming (range: 0 to 2), repetition (range: 0 to 1), comprehension (range: 0 to 3), reading (range: 0 to 1), writing (range: 0 to 1) and drawing (range: 0 to 1). Total score is the sum of sub-scores; total score ranges from 0 to 30, higher score indicates better cognitive state.
