| Other Pre-specified | Change in Pain Intensity in the Open-label, Active-controlled Treatment Period (Part 1) | Pain intensity was assessed by scoring "Pain right now" twice daily up to Day 14 by every participant using the Visual Analog Scale (VAS) as well as the Faces Pain Scale-Revised (FPS-R) in an electronic diary. Pain intensity was first documented using the VAS and directly thereafter the FPS-R. If required, pain intensity diary entry could be assisted by the legal guardian or a health care provider. The VAS is scored from 0, equivalent to "no pain", to 100, equivalent to "pain as bad as it could be". The FPS-R is a validated self-reported 6-point scale with 0 representing "no pain" and 10 representing "very much pain". Facial representations were used to indicate how much the pain hurts. The "pain right now" scores at baseline (last evaluation before starting IMP) and the mean of last 6 assessments collected up to the time point of last IMP intake in Part 1 (i.e., Day 14 or the day of early discontinuation) were used for the calculation of the change in pain intensity from baseline. | | Posted | | Mean | Standard Deviation | units on a scale | | From Baseline up to Day 14 (End of Part 1) or early discontinuation | | | | ID | Title | Description |
