FRAXA Research Foundation was honored to be part of the opening bell ringing ceremony at the New York Stock Exchange (NYSE) on July 5, 2018. We were there to raise awareness for Fragile X along side the National Fragile X Foundation. FRAXA President Katie Clapp and Director of Community Relations Dave Bjork attended with over 30 Fragile X family members and friends, including 4 self-advocates. This was a great opportunity to raise awareness of Fragile X on a big stage at an iconic place. The event was also carried live on television on CNBC, giving FRAXA and Fragile X broad reach around the world.
Tetra Discovery Partners today announced the initiation of a Phase 2 study of BPN14770 as a potential treatment for Fragile X Syndrome, the most common genetic form of autism. A selective small molecule inhibitor of the phosphodiesterase type-4D (PDE4D) subtype, BPN14770 has shown the ability to improve the quality of connections between neurons and to improve multiple behavioral outcomes in the Fragile X mouse model.
Many medications are used to help people with Fragile X cope. But few clinical trials have been done on these drugs. Years ago FRAXA funded Dr. Craig Erickson to run a trial of aripiprazole (aka Abilify). FRAXA guest writer Hannah Miles recently caught up with Dr. Erickson to learn the results of the trial.
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.
FRAXA Research Foundation has renewed Dr. Elizabeth McCullagh’s 2017 FRAXA Fellowship for a second year. Dr. McCullagh and Principal Investigator Dr. Achem Klug are investigating the “cocktail party effect” in Fragile X mice. There is a specific circuit which allows us to discriminate between competing sound sources, helping us focus on a sound source of interest such as with a conversation partner. If clear differences are found in this circuit, they could be used as potential biomarkers for Fragile X clinical trials.
FRAXA Research Foundation and the Fragile X Research Foundation of Canada have awarded a grant of $100,000 over two years to Dr. Raymond Turner at the University of Calgary in Alberta, Canada. Dr. Turner and postdoctoral fellow Xiaoqin Zhan, PhD are attempting to reactivate a segment of FMRP to reverse symptoms of Fragile X in a mouse model of the disease to reduce abnormal behaviors.
Dr. Carol Wilkinson, MD PhD, and Dr. Charles Nelson, PhD, at the Labs of Cognitive Neuroscience at Boston Children’s Hospital are recruiting young boys with Fragile X syndrome (FXS) to participate in a study investigating how differences in brain activity affect learning, language, and behavior in FXS. If we can determine what distinguishes one brain from another, and if a drug works with a particular neural marker or set of neural markers, this would permit matching drugs based on objective biological markers, a personalized medicine, rather than defaulting to the current method of trial and error.
This 2017 grant of $90,000 over two years enabled Dr. Wilkinson to study EEG in young children with Fragile X syndrome at Boston’s Children’s Hospital. She is working with principal investigator, Dr. Charles Nelson, Professor of Pediatrics at Harvard Medical School and a specialist in cognitive neuroscience. Co-funded by the Autism Science Foundation and the Pierce Family Fragile X Foundation.
Like other boys with Fragile X syndrome, Bash is hoping for an effective treatment and ultimately a cure. I am hoping to assist in this research by running my first marathon on April 8, 2018. Please sponsor me to fund research through the FRAXA Research Foundation.
With funding from FRAXA, the Yale University team of Leonard Kaczmarek, PhD showed that the firing pattern of suditory neurons in response to repeated stimulation is severely abnormal in Fragile X mice. Based on these results, they are collaborating with the UK-based company Autifony to develop advanced compounds which may reverse these deficits.
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.
The 18th International Fragile X and Related Neurodevelopmental Disorders Workshop in Quebec, Canada, was a great success, featuring Fragile X much more heavily than any previous meeting in this series! We asked our speakers to summarize their work in their own words. These brief updates from researchers investigating Fragile X.
With a 2017 grant from FRAXA Research Foundation of $90,000, Dr. Andreas Frick’s team at Neurocentre Magendie, in France, will test non-invasive imaging using magnetic resonance imaging (MRI) as a potential biomarker for future Fragile X syndrome clinical trials.
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
Today the 18th International Fragile X and Related Neurodevelopmental Disorders Workshop kicks off in Quebec, Canada. For the next six days, scientists from around the world will gather at this workshop to focus on recent breakthroughs in our understanding of Fragile X, autism spectrum disorders (ASD), and related neurodevelopmental disorders. This biennial meeting has been instrumental to the discovery of many disease-causing genes and the development of therapeutic strategies for these disorders.
This 2017 grant of $90,000 is funded jointly by FRAXA and the Fragile X Research Foundation of Canada. A previous FRAXA grant to the Sonenberg lab has led to great interest in the available drug, metformin, as a potential treatment for Fragile X syndrome. FRAXA is currently organizing clinical trials of metformin.
Almost all brain research focuses on neurons – nerve cells. However, the brain has many more glial cells which support, nourish, and protect the neurons. FRAXA Research Foundation awarded a 2017 grant $90,000 to support Dr. Yang’s studies of how changes in glial cells contribute to Fragile X syndrome. This grant is funded by a grant from the Pierce Family Fragile X Foundation.
FRAXA is proud to make a 2017 grant of $90,000 over two years to Clinton Canal, PhD. Dr. Canal, previously a research assistant professor at Northeastern University, has just launched his own lab at Mercer University in Atlanta, GA. He and his graduate students are fully committed to Fragile X research.
On Thursday, September 7 over 150 friends of FRAXA joined us at the Smith Barn at the Peabody Historical Society for the second annual FRAXA Fall Fling. Together we raised over $75,000 for Fragile X research — including a hand-delivered check for $25,000! Families from as far away as Miami, Florida joined us, even with hurricane Irma approaching their home state. Unfortunately, Irma ambushed Weather Channel Storm Tracker and Fragile X parent, Jim Cantore.
With a $45,000 grant from FRAXA Research Foundation in 2009, Dr. Mark Bear and Dr. Asha Bhakar used High Content Screening (HCS) to develop an assay sensitive to the effect of the FXS genotype. This project was funded in full by NIH after the first year.
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.
July 22 is National Fragile X Awareness Day, but I’ll bet few know the history behind it.
In 2000, before there was such a thing as a Fragile X Advocacy Day, FRAXA Research Foundation and David Busby (husband to Mary Beth, father to two adult sons living with Fragile X, a member of FRAXA’s pioneering leadership team, and a prominent and politically well-connected DC lawyer) were running Fragile X advocacy in Washington, DC.
“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.
With a $60,000 grant from FRAXA Research Foundation in 2015 that was renewed in 2016, Dr. Eric Klann of New York University will research biomarkers in fraile X syndrome and how to translate these markers from mouse models to human patients.
FRAXA Research Foundation, which is committed to finding a cure for Fragile X syndrome, the leading known inherited cause of intellectual disabilities and autism, has named Dave Bjork to the newly created position of Director of Development.
