Brief Summary:
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.

Primary Outcome Measures :
  1. Numeric Rating Scale (NRS) [ Time Frame: 6 Weeks ]
    Compare Numeric Rating Scale (NRS) scores Before Procedure,15-Minute Post Treatment, 30-Minutes Post Treatment, 24-Hour Post Treatment for all 12 treatments (Marcaine vs. Saline). NRS is a likert scale ranging from 0-10 with 0 being no pain and 10 being worst possible pain. For each individual time point, all 12 treatments were averaged for that time point and a single value was used for comparison between the two groups.


Secondary Outcome Measures :
  1. Change in Numeric Rating Scale (NRS) [ Time Frame: 15 Minutes Post Treatment, 30 minutes Post Treatment and 24 hours Post Treatment, assessed up to 6 weeks ]
    Compare percentage change in Numeric Rating Scale (NRS) score from Before Procedure to 15-Minutes, Before Procedure to 30-Minutes, Before Procedure to 24-Hours After Procedure for all 12 treatments (Mean of all 12 treatments for each timepoint, comparing Group A to Group B). NRS is a likert scale ranging from 0-10 with 0 being no pain and 10 being worst possible pain.

  2. Patient's Global Impression of Change (PGIC) [ Time Frame: 30 minutes Post Treatment and 24 hours Post Treatment, assessed up to 6 weeks ]
    Compare 24-Hour After Procedure Patient's Global Impression of Change (PGIC) score for 12 treatments (Mean of all 12 treatments for each timepoint, comparing Group A to Group B). PGIC is a likert scale ranging from 1 to 7 with 1 being very much improved and 7 being very much worse.

  3. Modified Pain Characteristic Questionnaire [ Time Frame: Before Treatment, 24 Hours After Treatment, 1 Month Post Treatment, and 6 Months Post Treatment ]
    Compare Modified Pain Characteristic Questionnaire scores Before Procedure vs. 24-Hour After Procedure, Before Procedure vs. 1-Month Follow Up, and Before Procedure vs. 6-Month Follow Up (Mean of all 12 treatments for each timepoint, comparing Group A to Group B). The modified pain characteristic questionnaire is a series of 11 questions on a likert scale ranging from 0 to 10 with 0 being no pain or does not interfere and 10 being worst pain or completely interferes. Percentage questions range from 0 to 100.

  4. Migraine Headache Days [ Time Frame: 12 Weeks ]
    Compare change in the number of migraine headache days per month reported in Baseline Period Diary vs. Treatment Period Diary vs. Post-Treatment Period Diary.

  5. Acute Medications Usage [ Time Frame: 10 Weeks ]
    Number of acute medications used during Treatment period (6 weeks) and Follow-Up (4 weeks) (Group A vs. Group B).

  6. Adverse Events [ Time Frame: 34 weeks ]
    Number of adverse events over the entire length of study (Group A vs. Group B).

  7. Headache Impact Test (HIT-6) [ Time Frame: 10 Weeks ]
    Total Headache Impact Test (HIT-6) scores Pre-Treatment at Visit 2 vs. Post-Treatment (following final treatment), and at 1-Month Post-Treatment (Group A vs. Group B). HIT-6 is a series of 6 likert scale questions ranging from 1 to 5 with 1 being never and 5 being always. The HIT-6 answer options are weighted as follows: Never (1) = 6 points each, Rarely (2) = 9 points each, Sometimes (3) = 10 points each, Very often (4) = 11 points each, Always (5) = 13 points each. The total score for the HIT-6 ranges from 36 (subject answers all 6 questions as "Never") to 78 subject answers all 6 questions as "Always"), with higher total scores indicating more impact than lower scores, i.e., headaches cause greater impact on the subject's life.

  8. Overall Satisfaction [ Time Frame: 10 Weeks ]
    Satisfaction scores Visit 2 vs. following treatment (Treatment 12) and at 1-Month Post-Treatment (Group A vs. Group B). Satisfaction scores are a likert scale ranging from 1 to 5 with 1 being complete dissatisfaction and 5 being complete satisfaction.
