• Sex: All
• Target Recruitment: 808

Inclusion Criteria

1. Male and female patients (18 years and older)
2. Chronic (for at least three months) non-specific pain in the lower back (between the lower ribcage and the gluteal folds)
3. Pain intensity on average at least 4 points on an 11-point NRS (one month before the start of the study)
4. Patients with indicated drug treatment* where previous optimised treatments** with non-opioid analgesics have not led to sufficient pain relief or were unsuitable due to contraindications or intolerance.
* Drug treatment is indicated if analgesic drug therapy is considered supportive for the realisation of activating measures, or if the patient has unbearable functional disabilities as a result of the pain, despite regularly performing these measures.
** Treatment is considered optimised when
I. a further increased drug dose is unsuitable from a medical perspective considering side effects and/or
II. it is not expected that a higher drug dose would result in a further advantage in terms of efficacy.
5. Willingness of both men and women to use a reliable method of contraception during study participation and for three months after taking the last dose of the IMP
6. Signed patient information and informed consent form
7. Understanding of the English language, ability to give consent and compliance
8. The patient has understood the instructions to avoid changes in lifestyle and dietary habits
9. The patient has understood the principle of the patient diary and gives their consent to keep it as instructed
Additional for Phase A
a1. The average value of the pain intensity in the morning of the 7 days before visit A2 (study week -1) must be at least 4 points on an 11-point NRS.
The last 7 entries of the pain intensity before visit A2 in the patient diary are used for the calculation (there must be at least 5 pain intensity
readings in the morning from the study week -1)
a2. Willingness not to take any analgesic medication (non-opioid and opioid analgesics as well as
adjuvant analgesics) during participation in study Phase A (except rescue medication)
a3. Willingness to continue a current non-drug therapy unchanged as planned during participation
in Phase A
Additional for Phase B
b1. Previous and complete participation in Phase A until and including Visit A6
b2. Patient wishes to participate voluntarily in the long-term study
b3. From the investigator's point of view, further participation is considered medically safe
b4. Willingness not to take any additional analgesic medication (non-opioid and opioid analgesics
as well as adjuvant analgesics) during the last two weeks of study Phase B (except rescue
medication).
Additional for Phase C
c1. Previous and complete participation in Phase B until and including Visit B10
c2. Patient wishes to participate voluntarily in the long-term study
c3. From the investigator's point of view, further participation is considered medically safe
Additional for Phase D
d1. Previous and complete participation in Phase B until and including Visit B10
d2. Patient has experienced a morning pain score improvement of at least 30% in treatment Phase B (mean morning pain score of study Week 43
compared to the mean morning pain score in the 7 days prior to visit A2 (study week -1), there must be at least four values
from study Week 43 and five values from study week -1)
d3. Patient wishes to participate voluntarily in the study
d4. From the investigator's

Exclusion Criteria

1. Professional groups for which the ability to operate machinery and drive vehicles is the primary activity (including truck, bus and forklift drivers,
pilots)
2. Alcohol/drug/medication abuse and previous or current intake of methadone in the patient's medical history or suspected by the investigator
3. Intake of analgesic medication (non-opioid and opioid analgesics as well as adjuvant analgesics) within seven days prior to the start of the study
4. Taking cannabis-based medicinal products within 30 days prior to the start of the study
5. HIV, dementia (which impairs the assessment of symptoms)
6. Severe forms of the following diseases: Anaemia, hematological/autoimmune/endocrinal/ renal/hepatic/respiratory/cardiovascular or
gastrointestinal diseases, symptomatic peripheral vascular diseases

pain currently or in the past, or individuals at risk of suicide (examined using the MINI questionnaire: when at least one module is fulfilled)

relative (parents and children); suicide in a first-degree relative (parents and children)

Additional for Phase A:
