Our friends at Stop SMA in Mississippi are preparing for their fundraiser, Laugh Away SMA, to be held at the end of this week, August 6 at 7:30PM. The event will bring two nationally known comics, Ralph Harris and Henry Cho, to Jackson, Mississippi and funds raised will support research for a cure for spinal muscular atrophy (SMA). Jeff Horton and his daughter Evie, the reason the Hortons started Stop SMA, appeared on their local NBC news to tell the community about the event and the disease. Check out the video below.

Several years ago, Chang and colleagues published the initial observation that sodium byturate appeared to improve survival and motor function in a mouse model of SMA. Spurred by these observations, Butchbach and colleagues in the Burghes laboratory at Ohio State University subsequently began to painstakingly study other butyrate derivatives. Some of these compounds, when administered early in the course of disease in the SMA animal model, significantly improved survival, but the timing of administration proved critically important. It was clear that the compounds varied in potency, and that any benefit diminished significantly if treatment intervention were delayed. However, one of these butyrate derivatives, sodium phenylbutyrate, had been in clinical use for decades in the treatment of newborn infants with urea cycle disorders. The hypothesis that this compound, given early in the course of the disease, might improve outcomes ultimately resulted in the launch of the STOP SMA study in 2006: a phase I/II open label Study of sodium phenylbutyrate in pre-symptomatic infants with Spinal Muscular Atrophy. These efforts have been generously supported by many: FightSMA, MDA, FSMA, and the Kylee Galbraith Memorial SMA Research Fund at the University of Utah, with medication graciously provided by Ucyclyd Pharma.

We completed enrollment for the STOP SMA trial in April 2010, and early results appear promising: of six infants expected to develop type I, survival and respiratory support needs are considerably improved compared to their affected siblings and symptomatic type I infants in the database, and one infant achieved independent sitting. In addition, two of six children expected to develop type II disease achieved independent walking. In addition to the improved motor outcomes, electrophysiologic data indicate that these children have less significant denervation than expected for age based on a natural history studies. However, the next few months will undoubtedly prove critical in moving this work forward to achieve the ultimate goal of this project: demonstrating the feasibility of rapid identification of newborns with SMA in order to permit early intervention for the many promising new therapies on the horizon.

Over the next year, we anticipate completion of the final dataset for the STOP SMA trial, data analysis and dissemination, development of a STOP SMA trial registry and database for prospectively identified SMA subjects, and planning for the next steps forward to identify infants via newborn screening, using a recently validated pilot newborn screening assay. For the STOP SMA protocol, we developed a proactive monitoring program with protocol-driven interventions for nutrition and respiratory care, modeled after the current cystic fibrosis clinic model. However, further pilot studies are necessary to determine how to best implement such a program in several states in anticipation of the launch of a nationwide prospective newborn follow-up program in infants diagnosed with SMA on newborn screening. Development of this database, and dissemination of best practices and proactive monitoring protocols to physicians and parents will improve the quality and length of life and the standard of care provided to children with SMA. We are extremely grateful for the additional funds provided via the Pepsi Challenge, Stop SMA and FightSMA at this crucial time to move this project forward as quickly and efficiently as possible.

After their daughter Evie was diagnosed with spinal muscular atrophy (SMA), Jeff and Dee Horton perceived a lack of knowledge and awareness of SMA in their community and even among many doctors. Desiring to do everything in their power to help Evie and others like her, the Hortons founded Stop SMA, a non-profit dedicated to battling SMA.

Now, Stop SMA is in the running to raise $250,000 for SMA research through the Pepsi Refresh Project. As of today, Stop SMA sits in 4th place among $250,000 candidates, but they need to be one of the top two when the end of the month rolls around to qualify for funding. Supporters can help move Stop SMA up the list by voting each day in March and asking their friends and family to do the same.
