UC Irvine Health pain expert to test Botox as migraine treatment for children

March 06, 2017

UC Irvine Health anesthesiologist Shalini Shah, MD, has received an American Society of Regional Anesthesia’s Chronic Pain Research Grant to study the safety and use of Botox in treating chronic migraines in children ages eight to 17.

“Onabotulinumtoxin A, better known as Botox, has been effectively used as a prevention therapy for many adults with chronic migraines since its FDA approval in 2010,” said Shah. However, there’s been no equivalent treatment approved for children.

“Over the last five years, I’ve selectively used this treatment ‘off label’ for pediatric patients whose migraines don’t respond to other treatments,” Shah said. “Anecdotally, the results are so impressive and have such a positive impact in these patients’ lives, that this therapy option ought to be studied in a controlled setting to demonstrate whether it has a clinical value and to validate existing treatment strategies.”

The medical literature estimates that one in three children will experience chronic headaches in their lifetime, which increases as they reach adolescence. Migraines make up nearly 60 percent of all visits to a pediatric headache specialist. 

The research, “Effectiveness of Onabotulinumtoxin A (Botox®) in Pediatric Patients Experiencing Migraines: A Randomized Double Blinded Placebo Crossover Study in the Pediatric Pain Population,” will receive just under $100,000 from ASRA over two years.  A clinical trial is planned, more information is available at ClinicalTrials.gov

No trials currently exist in literature studying onabotulinumtoxinA for efficacy and/or safety for pediatric migraine, although significant contributions have been made by retrospective case reviews over the last 10 years.

Shah is an assistant professor in the Department of Anesthesiology and Perioperative Care at the University of California, Irvine. She is also the director of the UC Irvine Health Pediatric Pain Services and associate director of Pain Medicine Fellowship at UC Irvine Health.

Migraines make up nearly 60 percent of all visits to a pediatric headache specialist.  Scientists 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. 

Among adults, it’s estimated that health care costs are 70 percent higher for a family with a migraine sufferer than without, 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.
