fNIRS to Measure Treatment Response in Young Children with Fragile X

FRAXA Research Foundation

FRAXA Research Foundation has awarded a $90,000 research grant to Dr. Craig Erickson and Dr. Elizabeth Smith at Cincinnati Children’s Hospital to test functional near-infrared spectroscopy (fNIRS), in children who have Fragile X syndrome. fNIRS is safe, non-invasive, and easily-tolerated. It uses light sources and sensors on the scalp to build a heat map of the brain in action.

FXS Patients’ Social Deficits are Linked to Social Anxiety, Eye-tracking Study Says

Fragile X News Today

Dr. Craig Erickson and colleagues at the University of Cincinnati used eye-tracking technology to understand sociability in Fragile X syndrome. This study affirms what so many parents, caretakers, and educators suspect: people with fragile X want to be social, and it is anxiety – not lack of interest – which usually hold them back. If anxiety could be reduced, more sociability would likely follow. Dr. Erickson is a Fragile X expert and FRAXA investigator who is currently conducting a Fragile X clinical trial of an investigational new drug.

Impact of the Fragile X Community

Dave Bjork

At FRAXA Research Foundation, we are truly grateful for our Fragile X community and thousands of donors. We couldn’t keep moving the ball forward in research without your support. Each year FRAXA invests over $1 million in Fragile X research thanks to your support. Because we supported these three researchers, we were able to secure another $35 million in research aimed at identifying clinical trial outcome measures that will lead to human trials of promising treatments for those affected by Fragile X.

Brain Imbalance Target of Dr. Erickson’s New Clinical Trial

Theodore Coutilish
Craig Erickson lab

According to Dr. Erickson, AZD7325 is a drug that selectively boosts GABA neurotransmission in the brain. GABA is the primary neurochemical in the brain that blocks brain activation. GABA activity is in balance in the brain with Glutamate activity, which is the primary neurochemical that causes brain activation. In Fragile X, GABA activity is insufficient and glutamate activity is excessive, likely causing brain activity to be out of balance. AZD7325 attempts to correct parts of this imbalance by boosting the insufficient GABA activity in the brains of people with Fragile X.

Development of a Novel GABA-A Agonist in Fragile X Syndrome

FRAXA Research Foundation
Tori Shaeffer

Of the many genes known to be regulated by FMRP, the gamma-aminobutyric acid receptor A (GABA(A)), is gaining attention as a potential target for the treatment of FXS. Mounting evidence suggests decreased expression and functioning of GABA(A) is involved in the pathophysiology of FXS. Non-selective GABA(A) agonism in animal models of FXS has been associated with normalization of morphological features, GABA(A) expression, and behavior. However, the clinical use of these agents in Fragile X is associated with unwanted side-effects, such as sedation, dulling of cognition, and occasional paradoxical agitation, which limits their use.

Development of a Novel GABA(A) a2,3 Agonist in Fragile X Syndrome

FRAXA Research Foundation

FRAXA Research Foundation awards $21,000 in 2013 to Dr. Schaeffer to analyze an investigational new compound that targets the GABA-A receptor. This study has led to a clinical trial of the compound, led by Dr. Craig Erickson at Cincinnati Children’s Hospital. Of the many genes known to be regulated by FMRP, the gamma-aminobutyric acid receptor A (GABA(A)), is gaining attention as a potential target for the treatment of FXS. Mounting evidence suggests decreased expression and functioning of GABA(A) is involved in the pathophysiology of FXS.
