Daily, Encapsulated, Green Tea Extract (GTE) to Mitigate Neuropathic Pain in Patients With Established Cancer-Associated Neuropathic Pain
University of Alabama at Birmingham
Summary
The overall objective of this study is to test an intervention of green tea extract (GTE) to mitigate neuropathic pain in patients, specifically cancer survivors, receiving supportive palliative care. Our central hypothesis is that daily, oral, encapsulated GTE will mitigate neuropathic pain, as longitudinally measured by the validated Douleur Neuropathique 4 (DN4) and blood protein biomarkers reported to be linked to the development and/or chronicity of neuropathic pain.
