Primary | Change in POM Between Baseline and Day 2 Evening, 1 Hour After Drug Application | Pain on movement (POM) was used to assess pain measurement for back and neck pain. The standardized movements have been established for which the measurement was taken. POMwp was the POM measure that gave the highest score at baseline; i.e. POM of worst procedure. Pain intensity was assessed at rest after standing in an upright position relatively motionless for 1 minute. The pain was evaluated by asking patient 'How would you rate your pain right now?' and by using a visual analogue scale (VAS) ranging from 0-10 centimeters (cm) wherein 0 cm = no pain to 10 cm = worst pain possible. The results presented here are adjusted mean change from baseline and standard error for POMwp in cm. | Baseline and Day 2 | |
Secondary | POMwp Area Under the Curve (AUC) Calculated From 0 to 72 Hours (h) (POMwp AUC(0-72 h)) | This is a key secondary endpoint. AUC for POMwp calculated from 0 to 72 h that is for first three treatment days using the trapezoidal rule divided by the observation time. The results presented here are adjusted mean and standard error for POMwp AUC (0-72 h) in centimeters (cm). The AUC represents POMwp as an average over the first 3 treatment days (Day 1 until Day 4 morning) - it is not meant here as a pharmacokinetics (PK) parameter (concentration over time). | 0 to 72 hours after start of treatment | |
Secondary | POMwp Area Under the Curve (AUC) Calculated From 0 to 120 Hours (h) (POMwp AUC(0-120 h)) | This is a key secondary endpoint. AUC for POMwp calculated from 0 to 120 h that is for first five treatment days using the trapezoidal rule divided by the observation time. The results presented here are adjusted mean and standard error for POMwp AUC (0-120 h) in centimeters (cm). The AUC represents POMwp as an average over the first 5 treatment days (Day 1 until Day 6 morning) - it is not meant here as a PK parameter (concentration over time). | 0 to 120 hours after start of treatment | |
Secondary | Number of Patients With Decrease in POMwp of at Least 30% From Baseline | This outcome measures the pattern of number of patients with a decrease in POMwp of at least 30% from baseline at 1 hour after dosing on Day 2 evening. | Baseline and day 2 | |
Secondary | Number of Patients With Decrease in POMwp of at Least 50% From Baseline | This outcome measures the pattern of number of patients with a decrease in POMwp of at least 50% from baseline at 1 hour after dosing on Day 2 evening. | Baseline and day 2 | |
Secondary | Change From Baseline in POMwp (cm) at Day 6 Morning | Pain on movement (POM) was used to assess pain measurement for back and neck pain. The standardized movements have been established for which the measurement was taken. POMwp was the POM measure that gave the highest score at baseline; i.e. POM of worst procedure. Pain intensity was assessed at rest after standing in an upright position relatively motionless for 1 minute. The pain was evaluated by asking patient 'How would you rate your pain right now?' and by using a visual analogue scale (VAS) ranging from 0-10 cm wherein 0 cm = no pain to 10 cm = worst pain possible. The results presented here are adjusted mean change from baseline and standard error for POMwp in centimeters (cm). | Baseline and Day 6 | |
Secondary | Change From Baseline in Pressure Algometry (PA) at Day 2 Evening, Before Drug Application | PA is a method described to determine pressure pain threshold (PPT) by applying controlled pressure to a given body point. The results presented here are adjusted mean change from baseline and standard error for PA. | Baseline and Day 2 | |
Secondary | Change From Baseline in Pressure Algometry (PA) at Day 6 Morning | PA is a method described to determine pressure pain threshold (PPT) by applying controlled pressure to a given body point. The results presented here are adjusted mean change from baseline and standard error for PA. | Baseline and Day 6 |
