Inclusion Criteria:

• Have given written informed consent approved by the relevant Ethics Committee (EC) governing the study site

PNP disease diagnosis inclusion criteria:

• Patient with chronic PNP supported by a distinct neuroanatomical plausible distribution with sensory signs and symptoms, and consecutive to one of the following causes: a traumatic event, a surgical procedure (excluding limb amputation), radiculopathy, post-herpetic or post-zooster neuralgia, diabetic polyneuropathy or post-anticancer chemotherapy. Diagnosis will have to be confirmed by the DN4 questionnaire at the screening visit (pain is considered as neuropathic if DN4 score = 4)

• Pain present since at least 6 months

• Patients will be required to have a score between 4 and 8 inclusive on the mean Average Pain Score (APS) Numeric Rating Scale (NRS) during the baseline period preceding randomization (data collected in patient diary) and to have completed at least 4 days of pain assessment

Exclusion Criteria:

• Pregnant, breastfeeding, or willing to be pregnant within 2 months

• With a current or recent history, as determined by the Investigator, of severe, progressive, and/or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, cardiac, neurological, or cerebral disease which would interfere with the patient's participation in the study

• Uncontrolled epilepsy

• Any current primary psychiatric condition, including major depression or major personality disorders (such as Axe II of Diagnostic and Statistical Manual of Mental Disorders (DSM-IV); personality disorders and mental retardation)

• Alcohol dependence or regular use of known drugs of abuse (e.g., amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, methadone, opiates, and phencyclidine)

• Acute disease state within 7 days before Visit 2

• Any other relevant medical disorder likely to interfere with the trial or represent a risk for the patient

• Any close relationship with the Investigators or the Sponsor (i.e. belonging to immediate family or subordination link)

• Patient under legal protection, according to the national law

• Patient currently enrolled in a clinical trial involving use of an investigational drug or device, or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study, or in an exclusion period according to national law

Exclusion criteria related to PNP:

• Neuropathic pain due to trigeminal neuralgia, central pain, complex regional pain syndrome and phantom limb pain

• Plan to have a session of physiotherapy or comportemental therapy such as gestion of pain, hypnosis, sophrology, meditation program during the study

• Have initiated or have planned an electrical stimulation (or neurostimulation) therapy within 2 weeks prior to Visit 1 or during the study period up to Visit 5

• Patient changed his/her " regular therapy " in the last 4 months

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patient 's Change From Baseline of Pain Severity as Measured by the Weekly Means of the Daily Average Pain Scores (APS) During 4 Weeks of Treatment	11-point Numeric Rating Scale (NRS). Scale from 0 to 10, 0 meaning no pain, 10 pain as bad as you can imagine. Lower values represent a better outcome. Unit: arithmetic average of 7 days of a 11-point NRS	Time zero equals baseline (Day 1) up to Day 42
Secondary	Patient 's Change From Baseline of Pain Severity as Measured by the Weekly Means of the Daily Worst Pain Scores (WPS)	11-point Numeric Rating Scale (NRS) Scale from 0 to 10, 0 meaning no pain, 10 pain as bad as you can imagine. Lower values represent a better outcome. Unit: arithmetic average of 7 days of a 11-point NRS	Time zero equals baseline (Day 1) up to Day 42
Secondary	Patient's Change From Baseline of Investigator Global Assessment of Change (IGAC)	IGAC is an investigator subjective evaluation of patient condition using a NRS from 0 to 10 with 0 meaning best and 10 worst Lower values represent a better outcome.	Time zero equals baseline (Day 1) up to Day 28
Secondary	Patient's Change of Pain Intensity After Heat Pain Stimuli From Baseline to End of Treatment Period	11-point Numeric Rating Scale (NRS) from 0 to 10; 0 meaning no pain, 10 pain as bad as you can imagine Lower values represent a better outcome Unit: arithmetic average on 6 reported scores per Visit.	Time zero equals baseline (Day 1) up to Day 28
Secondary	Patient 's Change From Baseline of Pain Severity as Measured by the Weekly Means of the Brief Pain Inventory (BPI).	Arithmetic average of 3 questions on an 11-point Numeric Rating Scale (NRS) from 0 to 10, 0 meaning no pain, 10 pain as bad as you can imagine.; Lower values represent a better outcome	Time zero equals baseline (Day 1) up to Day 28
