入选标准
- •Recruitment
- •Age above 18 years;
- •Neuropathic pain of at least 4/10 for at least 6 months;
- •Mechanical hyperalgesia;
- •One of the following diagnoses: peripheral nerve lesion, plexus lesion, radicular lesion, spinal lesion, polyneuropathy, postzosteric neuralgia, complex regional pain syndrome (CRPS);
- •No nerve block or other interventional treatment for at least 4 weeks;
- •Constant medication for at least 4 weeks;
- •Signed informed consent;
- •WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of study medication;
- •Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 4 weeks after the study in such a manner that the risk of pregnancy is minimized.
- •WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or is not postmenopausal [defined as amenorrhea >= 12 consecutive months; or women on hormone replacement therapy (HRT) with documented serum follicle stimulating hormone (FSH) level > 35mIU/mL]. Even women who are using oral, implanted or injectable contraceptive hormones or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy or practicing abstinence or where partner is sterile (e.g., vasectomy), should be considered to be of child bearing potential.
- •Enrolment open titration
- •All principal inclusion criteria at recruitment
- •Relevant mechanical hyperalgesia: SRF affected/control at least 2.0 with a minimal SRF of 0.8. Extended specification for polyneuropathy: SRF outside normal range on one foot (normal range: women und 40 years: SRF > 4,65, women above 40 years: SRF > 5,71; men under 40 years: SRF > 7,10, men above 40 years: SRF> 4,49) OR SRF within normal range, but SRF affected/control at least 2.0 with a minimal SRF of 0.8 with a control region located at the ipsilateral hand.
- •Enrolment double-blind phase
- •At least 30% reduction in mechanical hyperalgesia (SRF) (=”clinically meaningful reduction”) in the open titration;
- •WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of study medication;
- •Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 4 weeks after the study (see above recruitment).
- •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
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range

- •give their consent for the participation in the study or influences the pain
- •perception;
- •- Concurrent atrioventricular block second degree or higher
- •- Concurrent renal failure (CLcr < 30 ml/min)
