SECONDARY outcome

Timeframe: Day 3

Population: FAS included participants who received at least one dose of investigation product, analyzed according to original treatment assignment.

The investigator assessed their clinical global impression of change compared to Baseline, based on physical examination, degree of muscle spasm (presence of muscle spasm assessment), reaction to palpation (presence of local pain assessment), limitation of range of motion, and evaluation of the patient's reported functional assessment (limitation of activities of daily living assessment). The following 5-point rating scale was used: "1 = worse", "2 = no change", "3 = slight improvement", "4 = moderate improvement", "5 = marked improvement".
