CHERTSEY, England, September 18, 2015 /PRNewswire/ --
Astellas Pharma Europe Ltd. today announced the European Commission has granted approval for a label extension for QUTENZA[TM] (capsaicin 8% patch) to include the treatment of adult diabetic patients with peripheral neuropathic pain, either alone or in combination with other medicinal products for pain.[1] The capsaicin 8% patch was first granted marketing authorisation by the European Commission in May 2009 with a licence that excluded adult patients with diabetes.[2],[3]

"This is significant for those suffering with the debilitating effects of painful diabetic peripheral neuropathy (pDPN) as they now have a new treatment option. This decision reinforces the efficacy and tolerability of the capsaicin 8% patch in a wide range of patients, as well as the commitment of Astellas to help patients with this difficult-to-treat condition," commented Kay Drake, Senior Vice President Marketing, Astellas Pharma EMEA.
The European Commission decision follows the positive opinion from the Committee for Medicinal Products for Human Use provided in July 2015.[1] The approval is based on outcomes of two clinical trials examining the efficacy and safety of the capsaicin 8% patch in patients with pDPN.[4],[5]
pDPN is a debilitating condition that may affect one in four patients with type 2 diabetes.[6] The capsaicin 8% patch acts by directly targeting the source of neuropathic pain. In non-diabetic patients it has demonstrated rapid, targeted pain relief directly to the area of pain giving patients significant pain relief for up to three months following a single application.[7],[8] Outcomes of clinical studies found the capsaicin 8% patch provided statistically significant improvements in pain relief and sleep quality in patients with pDPN, with no new safety issues associated with a single treatment or repeated treatment over 52 weeks.[4],[5]
Notes to Editors
About neuropathic pain
Neuropathic pain, a type of pain caused by a lesion or disease of the somatosensory nervous system,[9] is a well-characterised neurological condition, which has been estimated to affect approximately 7-8% of the general population in Europe.[10],[11] The pain intensity varies and can impact a person's quality of life, general health and social and economic well-being.[12]
About QUTENZA™ (capsaicin 8% patch)
The capsaicin 8% patch is approved by the European Medicines Agency for the treatment of peripheral neuropathic pain in adults either alone or in combination with other medicinal products for pain.[1] The capsaicin 8% patch is approved for use in 27 countries across Europe as of the end of 2014.
The capsaicin 8% patch delivers a high-dose of a synthetic form of capsaicin directly to the damaged pain sensing nerves in the skin that are the source of neuropathic pain. Applied to the area of pain, the high concentration of capsaicin contained in the patch is released into the skin where it overstimulates the pain sensing nerves. Overstimulating the pain sensing nerves makes them become "defunctionalised," effectively reducing their spontaneous activity and making them unresponsive to stimuli that normally cause pain for patients with peripheral neuropathic pain.[13] As a result of treatment-related discomfort, transient increases in blood pressure may occur during and shortly after treatment with the capsaicin 8% patch.[7] There have been reported cases of burns, including second degree burns, in patients treated with capsaicin patches.[2]
