Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Percentage change in health related quality of life (HRQOL) total score as assessed by the disease specific Norfolk scale [ Time Frame: Baseline till endpoint (discontinuation or End of Study visit) (up to 64 weeks) ]

Secondary Outcome Measures:
  • Neurological function as assessed by the Utah Early Neuropathy Scale (UENS) and sensory testing [ Time Frame: Baseline till End of Study (up to 64 weeks) ]
    Physicians measuring neurological function will be blinded to treatment

  • Tolerability of patch application by dermal assessment [ Time Frame: Screening till Last visit when QUTENZA patch is applied (up to 53 weeks) ]
  • Tolerability of patch application by "pain now" Numeric Pain Rating Scale (NPRS) scores after patch application [ Time Frame: Baseline till Last visit when QUTENZA patch is applied (up to 52 weeks) ]
    Assessed within 15 minutes and 60 minutes after patch removal.

  • Tolerability of patch application by rescue medication use [ Time Frame: Days 1 through 5 after each patch application ]
  • Adverse Events and serious adverse Events [ Time Frame: Screening visit through End of study visit (up to 65 weeks) ]
  • Vital Signs (heart rate and blood pressure) [ Time Frame: Screening visit through End of study visit (up to 65 weeks) ]
    In case of patch application to be performed within 15 minutes before topical anesthetic application and within 15 minutes after patch removal.

  • Laboratory Analyses [ Time Frame: Screening visit through End of study visit (up to 65 weeks) ]
    The tests performed at the screening visit will include Hematology: Red Blood Cell Count, White Blood Cell Count, Lymphocytes, Neutrophils, Eosinophils, Basophils, Monocytes, Hemoglobin, Hematocrit and Platelets. Biochemistry: Aspartate Aminotransferase (AST) and/or Alanine Aminotransferase (ALT), Alkaline Phosphatase, Sodium, Potassium, Blood Urea Nitrogen (BUN), Creatinine and Lipid profile. Subsequent HbA1c and lipid profile follow-up will be done at bi-monthly visits. The other tests will be performed if clinically indicated.

  • Intensity of neuropathic pain using "average pain" NPRS scores [ Time Frame: Screening visit through End of study visit (up to 65 weeks) ]
    Question 5 of Brief Pain Inventory-Diabetic Neuropathy (BPI-DN)

  • Brief Pain Inventory (BPI) pain severity index and pain interference index [ Time Frame: Screening visit through End of study visit (up to 65 weeks) ]
  • Patient Global Impression of Change [ Time Frame: After each patch re-application, from first patch re-application through End of Study visit (up to 56 weeks) ]
  • Generic HRQOL measured by European Quality of Life - 5 Dimensions (EQ-5D) questionnaire [ Time Frame: After each patch application, from first patch application through End of Study (up to 64 weeks) ]
  • Treatment satisfaction using the Self-Assessment of Treatment (SAT) questionnaire at week 12/End Of Study visit [ Time Frame: End of Study (up to 65 weeks) ]

Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1. Qutenza 30 minutes + SOC Drug: QUTENZA
A Qutenza (8% capsaicin) patch will be applied to identified painful areas for 30 minutes (Arm 1) or 60 minutes (Arm 2).
Other Name: Capsaisin
Experimental: 2. Qutenza 60 minutes + SOC Drug: QUTENZA
A Qutenza (8% capsaicin) patch will be applied to identified painful areas for 30 minutes (Arm 1) or 60 minutes (Arm 2).
Other Name: Capsaisin
No Intervention: 3. SOC
Subjects randomized to this group will receive treatment optimized for them on an individual basis. The investigator will be free to provide whatever pharmacological or other treatment is considered optimal for management of the subject's pain.

Detailed Description:
Patients will be divided into 3 groups of approximately equal size. In the first group, patients will receive a QUTENZA patch applied for 30 minutes to the feet; in the second group, patients will receive a QUTENZA patch applied for 60 minutes to the feet. In both these groups patients will also continue to receive their normal treatment (Standard of Care (SOC)) for their peripheral neuropathic pain (PNP) and may receive further QUTENZA patch applications in the same way during the study. The third group will not receive a QUTENZA patch but will continue to receive their normal treatment for their neuropathic pain (SOC). Subjects will be involved in the study for up to 15 months and will have to visit the clinic at least 9 times.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:
