Brief summary
This study aims to compare the analgesic activity of capsaicin patch 8% applications at 3 months interval each on the cervico-facial area versus a reference neuropathic treatment with amitriptyline in patients with head and neck cancer in remission and with sequelae neuropathic pain. In this phase II trial, patients will be assigned in one of the two treatment arms: * Arm A (Experimental arm): Capsaïcin patch (Qutenza®) * Arm B (standard arm): Amitriptyline (Laroxyl®) 130 patients will be included and will be followed during 9 months.
Interventions
DRUGCapsaïcin patch (Qutenza®)
Treatment by application of capsaicin 8% (Qutenza®) patches 3 months apart (Month 1, Month 4 and Month 7).
DRUGAmitriptyline (Laroxyl®)
Treatment by amitriptyline (oral solution 40mg/ml), for 9 months at the recommended dose of 25 mg to 75 mg daily.
