  • If no regular analgesic pretreatment is reported:
  • Subjects must have an average pain intensity score (NRS-3) greater than 6 points in the last 3 days prior to the Screening Visit and related to low back pain.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes

  • Non-stable dosing of selective serotonin reuptake inhibitors within 30 days before the Screening Visit (the doses must remain stable during the trial).
  • Key exclusion criteria (trial specific)
  • Presence of conditions other than low back pain that could confound the assessment or self evaluation of pain, e.g., anatomical deformities, significant skin conditions such as abscess or syndromes with widespread pain such as fibromyalgia.
  • Any concomitant painful condition that could interfere with the subject?s trial assessments or with their ability to differentiate low back pain from other painful conditions.
