- •Key inclusion criteria (trial specific) at the Enrollment Visit
- •6. Subjects must have a diagnosis of chronic low back pain; chronic pain defined as pain lasting for at least 3 months.
- •7. Subject’s pain must require a strong analgesic (defined as WHO step III) as judged by the Investigator.
- •8. The painDETECT diagnostic screening questionnaire score must be:
- •positive” or
- •unclear”.
- •If the subject is being treated with a stable regimen of centrally acting analgesics (opioids) and/or co-analgesics, even a negative” painDETECT score (but of at least 9) at the Enrollment Visit will be acceptable.
- •9. If under regular daily pretreatment with a WHO step II/step III opioid analgesic and/or a centrally acting co-analgesic:
- •Subjects must be taking a WHO step II or step III analgesic or co-analgesic on a daily basis for at least 2 weeks prior to the Enrollment Visit.
- •Subjects pretreated with a WHO step II opioid analgesic and/or a centrally acting co-analgesic must have reported an average pain intensity score of at least 5 points (NRS-3 =5) during the last 3 days prior to the Enrollment Visit.
- •If under regular, daily pretreatment with a WHO step I analgesic monotherapy or if no regular analgesic pretreatment is reported:
- •Subjects must have an average pain intensity score of at least 6 points (NRS-3 =6) in the last 3 days prior to the Enrollment Visit.
- •Key inclusion criteria at the Baseline Visit
- •10. To be eligible to enter the trial, the subjects have to fulfill the inclusion criteria and not meet any of the exclusion criteria at the Enrollment Visit. The following criteria have to be confirmed at the Baseline Visit after 3 days to 2 weeks of washout of opioids and centrally acting co-analgesics and after the results of the laboratory analyses have been received).
- •Subjects must have an average pain intensity score (NRS-3) of at least 6 points (NRS-3 =6).
- •Subjects must score positive” or unclear” on the painDETECT diagnostic screening questionnaire at the Baseline Visit.
- •Subjects must have an increase of at least 1 point on the NRS-3 compared with the Enrollment Visit if under regular previous analgesic therapy with a WHO step II or step III opioid (post washout).
- •Subjects will only receive IMP if documentation is available showing that
- •they comply with these inclusion criteria.
