Women of childbearing potential must have a confirmed negative urine pregnancy test at the screening visit (V1) and at the randomization visit (V2).
· Diagnosis of type 1 or 2 diabetes mellitus (by American Diabetic Association Clinical
Practice Recommendations diagnostic criteria www.diabetes.org) for at least 1 year;
Hemoglobin A1c levels of =11% at V1 (with fluctuations of =1% in the three months
prior to this, established by comparison of V1 HbA1c result with an HbA1c result
obtained between 6-12 weeks before V1) and at V1 completion of a diabetes treatment
checklist (see Appendix A), demonstrating optimal diabetic control.· Diagnosis of painful, distal, symmetrical, sensorimotor polyneuropathy, which is due to diabetes, for at least 1 year.
· Patients at V1 must have a score =40 mm on the Pain Visual Analogue Scale (VAS).
· Normal chest x-ray within 1 year prior to V1; or stable x-ray defined as no clinically significant change from previous exam (if none available, x-ray must be taken at V1).
· Patients must be able to understand and cooperate with trial procedures, and have signed a written informed consent prior to entering the trial.

Exclusion Criteria

· Malignancy within the past 2 years with the exception of basal cell carcinoma.
· Patients with significant hepatic impairment (i.e. AST/ALT > 2x ULN, Total bilirubin >2 x ULN).
· Clinically significant abnormal 12-lead ECG (in the opinion of the investigator).
· Neurological disorders unrelated to diabetic neuropathy that may confuse the assessment of neuropathic pain.
· Any pain or other condition that may confound assessment or self-evaluation of the pain due to diabetic neuropathy.
· History of chronic hepatitis B or C, acute hepatitis A, B or C within the past 3 months, or HIV infection.
· Skin conditions in the area affected by the neuropathy that (in the opinion of the investigator) could alter sensation.
· Amputations other than toes.
· Administration of any investigational drug and/or agent within 30 days prior to screening.
· Use of prohibited medications, in the absence of appropriate washout phases.
· Abuse of drugs or alcohol within the last 2 years.
· Any serious or unstable medical conditions that, in the opinion of the investigator, would compromise participation in the trial.
· Any history of, or current, significant psychiatric disorder e.g. any DSM-IV Axis I or II Disorder or patients judged clinically to be a serious suicidal risk.
· History of recurrent syncope or hypotension (systolic <90mmHg, diastolic <40mmHg).
· Postural hypotension (a fall of 20mmHg in systolic BP or 10mmHg in diastolic BP on standing).
· History of transient ischemic attack or stroke.
· Carotid bruit, unless significant carotid stenosis (e.g. >70%) has been excluded by appropriate investigation.
· History of uncontrolled narrow angle glaucoma.
· History of a seizure disorder.
· Previous exposure to reboxetine.
· History of urinary retention or prostatic hypertrophy (unless surgically corrected e.g. by TURP).
