Study Examines Behavioral Traits of Fragile X Patients Without Autism
Patients with Fragile X syndrome who don’t meet the cut-off for a diagnosis of autism show a decrease in impulsivity and repetitive questioning over time, when compared with patients who do, a new study shows.
Drug Repurposing Study Results Accelerate Progress Towards Fragile X Treatments
While there are over 8,000 rare diseases affecting an estimated 350 million people worldwide, only around 200 of these conditions have effective treatments. Due to the high cost of developing new drugs, rare diseases have historically been less attractive to pharmaceutical companies. Drug repurposing systematically leverages the detailed information available on approved drugs and reduces the time and money needed to deliver safe “new” treatments, but with greater success rates and a potentially more immediate impact on health care.
In Their Own Words: Reports From the International Fragile X Workshop
The 18th International Fragile X Workshop in Quebec was a great success, featuring more Fragile X research than ever before!
Brain Imbalance Target of Dr. Erickson’s New Clinical Trial
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.

Neural Markers of Fragile X: A Powerful New Tool for Clinical Trials
Once the neural marker is identified for a particular challenge, such as kids with poor language versus good language, neural markers can be measured during drug and behavioral therapy trials to see if a child is improving based on objective biological measures.
Fragile X Awareness Day Origins and a Tribute
Did you know? National Fragile X Awareness Day began in 2000, thanks to FRAXA and advocate David Busby’s work in Washington, DC.
Metformin, Diabetes Drug, Potential Fragile X Treatment
"We treated mice with metformin and corrected all the core Fragile X deficits. We are optimistic about using metformin in human clinical trials. This is a generic drug with few side effects" says Nahum Sonenberg, PhD, James McGill Professor, Department of Biochemistry, McGill Cancer Center, McGill University.
Repurposing Available Drugs to Treat Fragile X Syndrome – FRAXA Initiatives
FRAXA Research Foundation was founded in 1994 to fund biomedical research aimed at finding a cure for Fragile X syndrome and, ultimately, autism. We prioritize translational research with the potential to lead to improved treatments for Fragile X in the near term. Our early efforts involved supporting a great deal of basic neuroscience to understand the cause of Fragile X. By 1996, these efforts had already begun to yield results useful for drug repurposing. To date, FRAXA has funded well over $25 million in research, with over $3 million of that for repurposing existing drugs for Fragile X.
A Kinase Assay as a Biomarker for Fragile X Syndrome
Dr. Frank Kooy at the University of Antwerp investigated whether phosphorylation abnormalities are a suitable biomarker for clinical trials in Fragile X syndrome.
NIH Investigator Carolyn Beebe Smith, PhD, Looks to Improve Sleep in Fragile X Syndrome
Our sons with Fragile X Syndrome typically go to bed early and rise early. Sometimes they jump on us while we are sleeping at 3 a.m., excited to start their day. For heaven’s sake, why? The answer may come from Carolyn Beebe Smith, PhD, senior investigator, Section on Neuroadaptation and Protein Metabolism, National Institute of Mental Health, National Institutes of Health, Bethesda, Maryland. She is studying why children, in particularly boys, with FXS have problems sleeping.
Mark Bear’s Goal: Disease-Modifying Treatments for Fragile X
Researcher Mark Bear, PhD, Picower Professor of Neuroscience, sees success developing disease-modifying treatments for Fragile X syndrome and other developmental brain disorders. Finally, hope. And it comes from his lab, The Picower Institute for Learning and Memory, Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology.
Sensory Hypersensibility in Fragile X Syndrome and BK Channel Openers
With $366,100 in FRAXA funding, researchers tested BK channel–opening drugs to fix sensory abnormalities in Fragile X mice; early results showed broad behavioral rescue.
Kimberly Huber, PhD, Explores Hyperexcitability in Fragile X Syndrome
What causes hyperexcitability? Dr. Kimberly Huber seeks to understand how FMRP regulates connections between brain cells and the function of brain circuits.
Identifying Biomarkers for Fragile X Syndrome – A Study in Argentina
Bio·mark·er, noun, a distinctive biological or biologically derived indicator of a process, event, or condition. Doesn’t help? Well, it’s perfectly clear to Argentinian researchers Patricia Cogram, PhD, and Paulina Carullo, MD, from the FLENI Institute in Buenos Aires, Argentina. They understand there is an urgent need for validated biomarkers after recent Fragile X syndrome clinical trials have failed on their primary endpoints.
