- •7. Average daily pain score = 4 based on the 11-point Numeric Rating Scale (NRS) at Visit 0, calculated from a minimum of four pain ratings in daily electronic device entries during the baseline period.
- •8. Women of childbearing potential must have a negative pregnancy test at Screening Visit and have to agree not to start a pregnancy from the signature of the informed consent up to thirty days after the last administration of the investigational product, using an appropriate birth control method, such as combined estrogen and progestogen containing hormonal contraception (e.g. oral, intravaginal, transdermal), progestogen-only hormonal contraception (e.g. oral, injectable, implantable), intrauterine device (IUD) or intrauterine hormone-releasing system (IUS) in combination with male condom, bilateral tubal occlusion, vasectomised partner, sexual abstinence.

排除标准

- •2. Any other form of non-diabetic distal symmetric polyneuropathy or any other pain condition that can impair the study endpoint (e.g. painful conditions where the intensity of pain is significantly more severe than the diabetic peripheral neuropathic pain).
- •3. Concomitant treatment with medications for pain management that could not be discontinued.
- •4. Concomitant treatment with potent CYP3A4 inhibitors (e.g. ketoconazole, ritonavir, indinavir) or drugs known to prolong QT interval.
- •5. Use of trazodone or gabapentin in the previous 3 months.

- •7. Use of high dose morphine (e.g. > 120 mg/day) at the Screening Visit.
- •8. Clinically significant abnormalities on physical examination, vital signs, ECG, laboratory tests at Screening Visit that in the opinion of Investigator would compromise patient’s participation in the study.
