Effectiveness Of Ecopipam in Treating Stuttering

Stuttering, an interruption in the flow of speech, affects about three million Americans. It begins most often in childhood, affecting four men for every woman.

Stuttering, a genetically influenced condition, appears to originate when various aspects of a young child’s development interact, and is best addressed with early intervention. No cure for it has been found, but behavioral treatment options are available. Currently, no Food and Drug Administration (FDA)-approved drug treatments are available.

In an attempt to find a new medicine, a research team at the School of Medicine at the University of California, Riverside, in partnership with the speech pathology laboratory at the University of Redlands, will conduct a study at CITrials in Riverside, Calif., to determine how effective ecopipam, an orally administered medication, is as treatment against stuttering.

Study Sheds Light on Stuttering Treatment
Stuttering is a speech disorder in which sounds, syllables or words are repeated or prolonged and it affects more than 70 million people worldwide.

‘A precise cause of the complex communicative disorder known as stuttering is not known yet.’

Ten volunteers will be selected to participate in the FDA-approved clinical trial. The study, scheduled to begin next month, is seeking volunteers, although space is limited. People interested in participating in the study may contact Gerald Maguire, M.D., the chair of psychiatry and neuroscience at UC Riverside and the associate dean for graduate medical education, who is leading the study: [email protected].

“The study is exploratory,” Maguire said. “We are the only site in the world conducting this trial; ecopipam has never been tested for stuttering. It has been tested for treatment of tics in Tourette syndrome, a neurological disease, with some encouraging results. Stuttering shares some similarities to the vocal changes seen in subjects with Tourette syndrome. We are hopeful ecopipam will yield beneficial effects in stuttering.”

Ecopipam is a first-in-class drug that selectively blocks the actions of the neurotransmitter dopamine at its receptor. Dopamine receptors can be broadly classified into two families based on their structures: D1 receptors and D2 receptors. Ecopipam blocks dopamine only at D1 receptors, and thus acts differently than other commercially available medications. This mechanism explains why ecopipam is being tested as a potential treatment for stuttering.

Children Respond Well to Speech Therapy to Overcome Stuttering
A study of 1600 children that tracked them from infancy till age of four found that one out of 10 children experience stuttering by the time they reach the age of four.

The 10 patients selected for the clinical trial next month will undergo a physical examination and their medical history will be recorded. To ensure that their stuttering symptoms are sufficiently severe, their speech patterns will be analyzed by Professor Lisa LaSalle, a speech pathologist at the University of Redlands, and co-investigator on the study. Each patient will receive ecopipam for a limited time.

“We believe we could have results from our analysis in as soon as nine months,” Maguire said. “A placebo-controlled clinical trial may then follow, pending approval. If ecopipam is found to be effective in controlling stuttering, we may have a viable solution for a disorder that can be traced back centuries.”

Breastfed Kids More Likely to Recover from Stuttering
Kids who are breastfed during infancy are more likely to recover from stuttering and return to fluent speech, according to a new study.

The study is being funded through philanthropic donations given to UCR specifically to study stuttering. Psyadon, a pharmaceutical company focused on treatments for neurology and psychiatry, will donate ecopipam.

Earlier this year, Maguire was elected chair of the board of directors of the National Stuttering Association (NSA), a non-profit organization dedicated to bringing hope and empowerment to children and adults who stutter.

Stuttering Linked to Mutations in 'Metabolic' Gene
A new study has said that mutations in a gene governing a metabolic pathway involved in recycling old cell parts is responsible for stuttering.

A professor of psychiatry and neuroscience and a stutterer himself, Maguire earned his medical degree from St. Louis University School of Medicine in 1991 and his residency in psychiatry in 1995 from UC Irvine. His research interests include the medical treatments of stuttering and the pharmacologic treatment of schizophrenia, bipolar disorder, major depressive disorder and Alzheimer’s dementia.
