  • 1. Subjects must be at least 18 years and not older than 80 years
  • 2. Subjects with a diagnosis of chronic post-surgical neuropathic pain after breast surgery (breast cancer interventions), chest surgery (i.e. thoracotomy, video assisted thoracoscopy and sternotomy) or groin hernia repair (i.e. femoral hernia repairs and inguinal hernia repairs)
  • 3. The chronic post-surgical pain developed or increased in intensity after the surgical procedure and persisted beyond the healing process, i.e. at least 3 months after the initiating event, as defined according to the international association for the study of pain (IASP) classification of chronic pain for ICD-11 (Schug et al., 2019)
  • 4. Subjects must have ‘probable’ or ‘definite’ neuropathic pain as assessed by the revised IASP special interest group on neuropathic pain (NeuPSIG) grading system (Finnerup et al., 2016)
  • 5. Subjects must be willing to discontinue and washout prohibited substances including
  • pain medications (e.g. antidepressants, anticonvulsants/antiepileptics, selective serotonin and dual reuptake inhibitors, long-acting benzodiazepines, muscle relaxants, and topical analgesics), except the rescue medication, and
  • substances known to be inhibitors or inducers of CYP2C9 and inhibitors of CYP3A4
  • for specific washout periods of at least 5 times the drug half-life
  • 6. Permitted concomitant medications must have been stable for at least 4 weeks prior to Day -14 and any non-pharmacological therapies (e.g. physiotherapy, acupuncture and transcutaneous electrical neural stimulation) must have been initiated at least 3 weeks prior to Screening
  • 7. Female subjects must not be pregnant or breastfeeding and be
  • of non-childbearing potential or
  • if of childbearing potential, use a highly effective contraceptive method from start of the IMP intake until 30 days after the last IMP intake and have a negative pregnancy test at Screening (blood test)
  • 8. Male subjects must agree, from start of the IMP intake until 3 months after the last IMP intake, to refrain from donating sperm and use a male condom when having sexual intercourse with a woman of childbearing potential at any time and advise her to use a highly effective contraceptive method
  • 9. Subjects must understand the nature of the study procedures and provide written informed consent prior to any study-related procedures
  • 10. Body weight =55 kg for men and =50 kg for women
  • 11. Body mass index (BMI) <35 kg/m²
  • Randomization criteria
  • 1. At least 5 daily pain assessments in the baseline week prior to randomization, with a mean score on the PI-NRS =4 and =9. Differences between the baseline daily pain scores on the PI-NRS must be =50%.
  • 2. For female subjects of childbearing potential: negative pregnancy test in urine on Day 1.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 54
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 40

排除标准

  • 1. Subjects with neuropathic pain not a result of a surgical procedure as defined in inclusion criterion 2
  • 2. Subjects with any other coexisting pain that cannot be discriminated from post-surgical neuropathic pain, in the opinion of the subject or clinician
  • 3. Subjects diagnosed with chronic post-surgical neuropathic pain with a disease duration exceeding 3 years
  • 4. Inability to participate in the study, in the opinion of the investigator, because of, for example, severe brain damage, language barrier, dementia, or other clinically significant or unstable conditions
  • 5. Subjects using adjuvant chemotherapy
  • 6. Creatinine clearance <60 mL/min using the Cockcroft-Gault formula
  • 7. White blood cell count <2500/mm³; neutrophil count <1500/mm³; platelet count <100 x 10³/mm³
  • 8. A history of multiple drug allergies
  • 9. History or presence of alcohol or drug abuse
  • 10. Subjects using strong opioids (e.g. a Morphine Equivalent Dose [MED] >80 mg/day)

  • 15. Clinically significant gastrointestinal conditions, likely interfering with the study medication, study procedures or the outcome of the study
  • 16. Positive test for human immunodeficiency virus (HIV)
  • 17. Positive test for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C antibody and/or HIV1/HIV2 antibody at Screening
