Number of Participants With Treatment Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs) |
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 Week 24 that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious adverse events. |

NIS is a standardized instrument used to evaluate participant for signs of peripheral neuropathy. NIS is the sum of scores of 37 items from both the left and right side, where 24 items scored from 0 (normal function) to 4 (extreme abnormal function), higher score indicates higher abnormality and 13 items scored from 0 (normal function) to 2 (extreme abnormal function), higher score indicates higher abnormality. NIS possible overall score ranged from 0 (no impairment) to 244 (maximum impairment), higher scores indicate increased impairment. |

WOMAC: self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms in participants with osteoarthritis of knee. WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis in the index knee during past 48 hours. It is calculated as mean of the scores from 5 individual questions scored on a numerical rating scale of 0 (minimum pain) to 10 (maximum pain), where higher scores indicate more pain.
