Females of child-bearing potential must agree to use a medically acceptable and reliable means of birth control during the study and for 1 month following the last dose of study drug. 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
Exclusion criteria: [10] Have a known hypersensitivity to duloxetine or pregabalin or any of the inactive ingredients or have any contraindication for the use of duloxetine or pregabalin. [11] Have uncontrolled narrow-angle glaucoma. [12] Have previously completed or withdrawn from this study or any other study investigating duloxetine or pregabalin or have previously been treated with duloxetine or pregabalin [13] Have received treatment with a monoamine oxidase inhibitor (MAOI) within 14 days prior to Visit 2, or have a potential need to use a MAOI during the study or within 5 days after discontinuation of study drug. [14] Have received fluoxetine within 30 days prior to randomisation. [15]Have acute liver injury (such as hepatitis) or severe cirrhosis (Child-Pugh Class C). [16] Have a serum creatinine greater than or equal1.5 mg/dL or a creatinine clearance <60 mL/min, at Visit 1. [17] Are judged clinically by the investigator to be at suicidal risk or as defined by a score of 2 or greater on Question 9 of the BDI-II, at inclusion or randomisation. [18] Have current, or a history of, substance abuse or dependence within the past year (e.g. amphetamines, barbiturates, cannabis, cocaine and opiates), excluding nicotine and caffeine. [19] Exclusion criterion [19] has been deleted. [20] Women who are breast-feeding. [21] Have a historical exposure to drugs known to cause neuropathy (for example, vincristine), or a history of a medical condition, including pernicious anaemia and hypothyroidism, that could have been responsible for neuropathy.

[23] Are investigator site personnel directly affiliated with this study and/or their immediate families. [24] Are employed by Lilly or Boehringer Ingelheim [25] At the time of study entry, are currently enrolled in, or have been discontinued within the last 30 days from, a clinical trial involving an off-label 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. [26] Have serious or unstable cardiovascular, hepatic, renal, respiratory or haematological illness; symptomatic peripheral vascular disease; a history of seizure disorder; or other medical (including unstable hypertension and not clinically euthyroid) or psychological conditions that, in the opinion of the investigator, would compromise participation or be likely to require hospitalisation during the course of the study.

Primary Outcome(s)
|
Main Objective: To evaluate whether treatment at standard doses with duloxetine (60 mg/day) in combination with pregabalin (300 mg/day) is superior to a maximal dose of duloxetine (120 mg/day) or pregabalin (600 mg/day) given as monotherapy, over an 8-week period, in patients with diabetic peripheral neuropathic pain, who don’t respond to a standard dose of either duloxetine or pregabalin after 8 weeks of initial treatment.
|
Primary end point(s): The BPI Modified Short Form (Cleeland and Ryan 1994) is a self-reported instrument that measures the severity of pain and the interference of pain on function. The primary efficacy measure will be the BPI Modified Short Form 24-hour average pain item score. This measures the severity of pain over the previous 24 hours
|
Secondary Objective: •To evaluate the efficacy of a duloxetine and pregabalin standard doses combination therapy versus a maximal dose of monotherapy with either pregabalin or duloxetine: -on the following measures over an 8-week period: Mean change in items of the BPI Modified Short Form Severity and Interference portions, means on the CGI-I and PGI I scales, response rates defined, mean change in pain components on the NPSI questionnaire -on mood symptoms (HADS). -on functional/health outcomes as measured by mean changes on the SDS. •To evaluate the safety of a duloxetine and pregabalin standard doses combination therapy versus a maximal dose of monotherapy with either pregabalin or duloxetine as measured by discontinuation rates, TEAEs and vital signs. •To compare the effect of a maximal dose of duloxetine monotherapy versus a maximal dose of a pregabalin monotherapy versus a standard dose of duloxetine and pregabalin combination therapy on resource utilisation
