Pain over the last 24 hours was assessed by using VAS score ranges from 0 millimeter (mm)=no pain to 100 mm=worst possible pain. An increase in score from baseline represented disease progression and decrease represented improvement.

Full analysis set included all participants who met the eligibility criteria, received study medication and had at least one post-treatment efiicacy assessment.

Full analysis set included all participants who met the eligibility criteria, received study medication and had at least one post-treatment efiicacy assessment. Last Observation Carried Forward (LOCF) method was used.

PID is defined as the amount of change in the pain intensity at each evaluation time point (at 2 and 4 hours after the study drug dosing) from the baseline for each participant. Pain Intensity was evaluated on a 4-stage scale ranging from 3=severe pain to 0=no pain. PID ranges from -3 (the worst) to +3 (the most improved).

Full analysis set included all participants who met the eligibility criteria, received study medication and had at least one post-treatment efiicacy assessment. Participants showing a Pain Intensity (PI) value of 0 prior to dosing at each evaluation time point were not included in the analysis.

Pain relief was evaluated based on a 5-stage scale from 4 (complete relief) to 0 (no relief). An increase in score represented improvement and decrease represented disease progression

Full analysis set included all participants who met the eligibility criteria, received study medication and had at least one post-treatment efiicacy assessment. Participants showing a Pain Intensity (PI) value of 0 prior to dosing at each evaluation time point were not included in the analysis.

PRID was sum of the PID and PAR for each participant at each evaluation time point (2 hours after dosing, 4 hours after dosing). Pain Intensity was evaluated on a 4-stage scale ranges from 3=severe pain to 0=no pain and PID ranges from -3 (the worst) to +3 (the most improved). PAR ranges from 0 (no improved) to +4 (the most improved). PRID ranges from -3 (the worst) to +7 (the most improved).

Full analysis set included all participants who met the eligibility criteria, received study medication and had at least one post-treatment efiicacy assessment. Participants showing a Pain Intensity (PI) value of 0 prior to dosing at each evaluation time point were not included in the analysis.

SF-36 is a metric for general health and Quality of Life (QOL), consists of 8 sub-scale indices related to health and QOL (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health). Each of the sub-scale scores ranged from 0 to 100, where higher values indicate a better health status or a better mental status.

Full analysis set included all participants who met the eligibility criteria, received study medication and had at least one post-treatment efiicacy assessment. 'N' (number of participants analyzed) signifies participants evaluable for this measure and n = the number of participants with measurements for that time point.
