Exclusion criteria
Exclusion criteria: • Pain of other origin that might confound the assessment of neuropathic pain of postherpetic origin • Active herpes zoster lesion or dermatitis of any origin at the affected site • Subjects who had neurological ablation by block or neurosurgical intervention for control of pain • Significant or unstable medical or psychiatric disorders • Drug or alcohol abuse in the preceding 2 years • Severe renal function impairment, as shown by calculated creatinine clearance values 2.0 times the upper limit of the normal, white blood cell count (WBC) <2,500 cells/mm3) • Previous participation in any study with eslicarbazepine acetate • Pregnancy or breast feeding • History of hypersensitivity to the investigational products or to drugs with a similar chemical structure • History of non-compliance • Likelihood of requiring treatment during the study period with drugs or other interventions not permitted by the clinical study protocol • Participation in a clinical study within 3 months prior to screening • Any clinical significant concomitant condition which might influence the assessments or conduct of the trial.

| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the study is to assess the efficacy of eslicarbazepine acetate (ESL) as therapy for patients with post-herpetic neuralgia. The primary efficacy variable will be based upon an 11-point (0-10) Numeric Rating Pain Scale (NRPS), where 0 = no pain and 10 = worst possible pain, to be recorded in a patient's diary upon awakening each morning. Other secondary efficacy variables will be: pain assessed via the sensory portion of the Short-Form McGill Pain Questionnaire (SF-MPQ), Patient Global Impression of Change (PGIC), Clinician Global Impression of Change (CGIC), the dynamic allodynia (evoked pain) assessed by the Allodynia Severity Rating Scale, sleep interference assessed by the Chronic Pain Sleep Inventory (CPSI®), quality of life assessed by the SF-36 Health Survey, and intake of rescue medication. ;Secondary Objective: The secondary objectives of the study are to assess the safety and tolerability of ESL in patients with post-herpetic neuralgia. The safety/tolerability variables will be: adverse events (AEs), standard laboratory safety data (haematology, biochemistry), 12-lead electrocardiogram (ECG), vital signs (blood pressure, heart rate), physical and neurological examinations.;Primary end point(s): Pain intensity of neuropathic pain of postherpetic origin will be assessed during treatment period. Change from mean pain from baseline to end of treatment will be the endpoint. | — |
