The purpose of the research is to examine the outcomes of pediatric patients receiving Botulinum toxin type A (Botox ®) for the treatment of migraine. There is limited literature on the effectiveness of Botox ® in the treatment of chronic neurological pain in pediatric patients, specifically in the treatment of migraines.
Medical Literature approximates one in three children will experience chronic headaches in their lifetime, which increases as children reach adolescence. Migraines make up nearly 60% of all visits to a pediatric headache specialist. Studies have demonstrated the negative impact of having childhood migraine on overall quality of life is similar to pediatric cancer, heart disease and rheumatic disease. As the frequency of migraine attacks increase, so does proportionally the child's disability in lost school time and family and social interactions, all of which may lead in turn to economic disability. Studies estimate the health care costs are 70% higher for a family with a migraine than a non-migraine affected family, and direct medical costs for children with migraine are reported to be similar to those for adults. A study published in JAMA 2003 found that health care costs, work-related disability for parents and lost educational opportunity for the child leads to an annual economic impact in the US of approximately $36 billion due to both direct medical costs and lost productivity into adulthood. Onaboutlinum (BOTOX) is currently FDA approved as a very successful treatment to prevent migraines in adults, however not yet children. Current treatments for migraine in children appear to be insufficient. No trials currently exist in literature prospectively studying onabotulinumtoxinA for efficacy and/or safety for indication of pediatric migraine, although significant contributions have been made by retrospective case series over the last 10 years. This research will be the first investigator-initiated study to study BOTOX (R) in children prospectively in a randomized controlled placebo, cross-over study. The overriding rationale is to demonstrate efficacy, tolerability and safety of onabotulinumtoxinA for pediatric migraine and thereby potentially hasten the lengthy process to evaluate BOTOX® for approval in the pediatric population.
Study Type
INTERVENTIONAL
Allocation
RANDOMIZED
Purpose
The AB subject group will receive OnabotulinumtoxinA in the first treatment and saline placebo in the second.Both groups will then receive OnabotulinumtoxinA in the last two treatments. There will be one treatment at the beginning of each 12 week block, meaning 4 treatments over the 48 week study period total. Progress check-ups will occur every 6 weeks during the study. Randomization will be via selection of sealed envelope.

Time frame: Baseline (4 weeks) and 12 weeks post each, respective intervention
Pediatric Migraine Disability Score (PedMIDAS)
Pediatric Migraine Disability Score consists of 6 questions: 3 addressing school attendance and functioning, and 3 evaluating participation in events outside of school. The questionnaire is based on the patient's recall of the previous 3 months. The questionnaire produces a raw score (0-10, 11-30, 31-50, \>50) corresponding to a disability grade with increasing severity (little to non, mild, moderate, and severe) which was coded (1, 2, 3, and 4).
Time frame: Baseline (4 weeks) and 12 weeks post each, respective intervention
Functionality Improvement
Improvement of functionality as determined by their Pediatric Migraine Disability Score (PedMIDAS). The PedMIDAS consists of 6 questions: 3 addressing school attendance and functioning, and 3 evaluating participation in events outside of school. The questionnaire is based on the patient's recall of the previous 3 months. The questionnaire produces a raw score (0-10, 11-30, 31-50, \>50) corresponding to a disability grade with increasing severity (little to non, mild, moderate, and severe) which was coded (1, 2, 3, and 4).
