Use of the Tx360 Nasal Applicator in the Treatment of Chronic Migraine
Completed · Phase 4
Conditions studied: Chronic Migraine
In brief
Migraine imposes a substantial burden on patients in terms of diminished daily functioning, quality of life, and financial loss. Pain severity and duration correlates with reduced measures of daily functioning, and overall health status. The sphenopalatine ganglion (SPG) has been implicated in a variety of cephalalgias. This has been well represented in the literature dating back over a century. Access to this structure can be gained via a small area of mucosa just posterior and superior to the tail of the middle turbinate on the lateral nasal wall. At this aspect, there is no bony boundary to the SPG. Blocking the SPG using local anesthetics relieves pain. Unfortunately, many current interventions are cumbersome, invasive, and expensive. The purpose of this study is to evaluate the efficacy of the Tx360™, a new nasal applicator device, in the treatment of head and face pain and to examine the economic implications. The Tx360™ is a single use device designed to deliver a topical local anesthetic to the specific area of mucosa associated with the SPG. A total of 42 study participants will be accepted into this double-blind placebo-controlled study. 28 will receive SPG blocks using a 0.3 mL of a 0.5% solution of Marcaine delivered by the Tx360™ while 14 will receive a placebo of saline substituted for the Marcaine. Both patient sets will also be given a piece of lemon hard candy as a taste distractor. Participants must have a chronic migraine history with over 15 symptomatic days per month over the past three months. The treatment plan consists of six weeks of treatment, two times per week. Short and longer term assessments will be retrieved and analyzed as detailed in the Study Design.
