The difference between active treatment and placebo in a clinical trial of an analgesic appears to depend on a variety of factors other than the actual efficacy of the drug itself, including various aspects of study design and conduct. One potential such factor is how information about the study is presented to research staff and patients. The purpose of this study is to examine the impact of different presentations of information on the difference between pregabalin and placebo observed in a clinical trial in patients with painful diabetic neuropathy.

  • Reports current suicidal ideation within the past 1month;
  • Has history of kidney disease that is likely to decrease creatinine clearance;
  • Has creatinine clearance below 60 as calculated by Cockroft-Gault equation for serum creatinine;
  • Has a history of drug or alcohol abuse within the past 1 year;
  • Has hypersensitivity, intolerance, or allergy to pregabalin or gabapentin;
  • Subject is pregnant, is considering becoming pregnant during the study, is breastfeeding or unwilling to use adequate birth control during the study;
  • Participated in another clinical trial within the past month;
  • Is involved in an ongoing or settled worker's compensation claim, disability, or litigation;
  • Has a known failure to respond to pregabalin or gabapentin at a clinically relevant dose due to either efficacy or tolerability;
  • Or has taken opioids on an as-needed basis within 1week of Screening, or has taken pregabalin or gabapentin within 30 days of screening. Subjects on stable doses opioids, antidepressants, non-steroidal anti-inflammatory drugs, or low-dose aspirin will be allowed to participate in the study
