The purpose of the study is to determine the efficacy of etoricoxib on pain patients. The investigators assume that patients with neuropathic pain will have greater pain relief then patients on placebo.

Condition Intervention Phase
Postherpetic Neuralgia
Peripheral Nerve Injury
Drug: Etoricoxib
Drug: placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Efficacy of Etoricoxib in Patients With Neuropathic Pain With and Without Peripheral Hyperalgesia - A Prove of Concept Trial

Primary Outcome Measures:
  • Superior improvement of peripheral hyperalgesia at day six after initiation of Cox-2-inhibiting-medication in comparison to placebo [ Time Frame: 12 month ]

Secondary Outcome Measures:
  • Reduction of the average on-going pain [ Time Frame: 12 month ]
    reduction of the average on-going pain decrease of the neuropathic symptoms intensity (NPSI score) decrease of the patients global impression of change (PGIC) decrease of the frequency and cumulative 7 day dosage of rescue medication

Enrollment: 9
Study Start Date: February 2011
Study Completion Date: August 2012
Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: etoricoxib, peripheral hyperalgesia
14 patient with neuropathic pain and peripheral hyperalgesia get etoricoxib 90mg for 8 days
Drug: Etoricoxib
the patients get etoricoxib 90mg for 8 days. They get one pill with 90mg per day
Other Name: Arcoxia
Active Comparator: etoricoxib, no peripheral hyperalgesia
14 patients with neuropathic pain without peripheral hyperalgesia get etoricoxib 90mg for 8 days
Drug: Etoricoxib
the patients get etoricoxib 90mg for 8 days. They get one pill with 90mg per day
Other Name: Arcoxia
Placebo Comparator: placebo, peripheral hyperalgesia
14 patients with neuropathic pain with peripheral hyperalgesia get placebo for 8 days
Drug: placebo
patients get one pill of placebo (sugar-pill) per day for 8 days.
Placebo Comparator: placebo, no peripheral hyperalgesia
14 patients with neuropathic pain without peripheral hyperalgesia get placebo for 8 days
Drug: placebo
patients get one pill of placebo (sugar-pill) per day for 8 days.

Detailed Description:
Animal experiments analysing anti-hyperalgesic effects of Coxibs show inconsistent results due to different used dosages and varying different pain models. Theoretical the use of NSAIDs is rational, particularly of Coxibs as a part of the neuropathic pain management. But in the newest topical review, there is no valid information available about the effectiveness of these drugs in human neuropathic pain models or in patients with different underlying mechanism, e.g. with or without hyperalgesia.

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

Inclusion Criteria:

  • Patients over 18 years with
  • Persistent moderate or severe pain (> 4 on NRS (1..10)) at rest (average of three daily assessments using a diary for at least two days) .
  • Neuropathic pain associated with a clinical and neurologically proven peripheral nerve injury, radiculopathy, postherpetic neuralgia or polyneuropathy or CRPS
  • One of the two following QST phenotypes at the baseline assessment:

    • signs of peripheral hyperalgesia (that means, pathological decreased heat pain threshold and/or pathological decreased muscle pain threshold)
    • without signs of peripheral hyperalgesia (no pathological decreased heat - and/or muscle pain threshold)
  • Patients of both gender
  • Signed consent form
  • Patients with the ability to understand and follow the instructions of the doctor

Exclusion Criteria:

  • Excluded will be patients Parkinson's disease or a history of cerebral vascular insult or nerve injury.

Excluded will be also all patients with contradictions for the use of Etoricoxib:

  • Hypersensitivity to the active substance or to any of the excipients.
  • Active peptic ulceration or active gastrointestinal (GI) bleeding.
