Newly Diagnosed with Fragile X – What Comes Next?

Theodore Coutilish Community February 22, 2018October 15, 2018

Jessica Haugen and Jeff Eliason received the phone call every parent dreads in October 2012. Their son’s pediatrician told them their son, Larry, then 1, had Fragile X syndrome (FXS) and “there’s nothing you can do about it.” The couple reacted similarly to how other newly diagnosed parents receiving these results. Denial. Discouragement. Depression.

Coming Full Circle – Kathy May Returns back to FRAXA

Theodore Coutilish FRAXA Updates November 15, 2017October 15, 2018

Co-Founder Kathy May Returns after Two Decades to Write Grants. It’s about discovering new forms of treatments to enhance the mental, emotional and social growth of those affected by Fragile X. “And there will be a cure,” she said. “FRAXA is the reason for this hope. I have come full circle to FRAXA and feeling more hopeful than I have in many years.”

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

Trial and No Error: Better Outcomes for Clinical Trials in Fragile X Syndrome

Theodore Coutilish Clinical • Research Updates December 14, 2016July 2, 2018

Johns Hopkins Researcher Christina Timmerman, PhD, Searches for a Less Subjective Method to Determine if a Drug is Working in Patients with Fragile X Syndrome Many parents of children with Fragile X syndrome were crushed when promising drug trials were unexpectedly stopped a few years ago because subjective behavior-based outcome measures did not justify continuing the trials. The strong feelings linger today. If all goes well with Christina Timmerman’s research, future drug trials may be able to continue with additional metrics for assessment, until there are advanced treatments or even a cure for Fragile X syndrome. This will be welcome news to parents. Timothy Gamache, graduate student, and Christina Timmerman, PhD “We hope a more quantitative outcome measure, such as the proposed microRNA biomarker, would allow for a less subjective method to determine if a drug is working or not,” said Dr. Timmerman, Postdoctoral Fellow, Lab of Mollie Meffert, DepartmentRead more

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, wHY, 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. “We know sleep is important for many aspects of brain function,” said Dr. Smith, who received a PhD from the University of London where she studied the chemical pathology of Alzheimer’s for which she was awarded the Queen Square Prize. “In studies of healthy mice, we have shown restricted sleep during brain development can result in long-lasting changes in behavior. We are interested in understanding if sleep problems contribute to severity ofRead more

Sensory Overload Ever wonder why your child with Fragile X suddenly screams for no apparent reason or jumps and flaps uncontrollably seemingly for hours? You got it: hyperexcitability. But what exactly causes it? And what can fix it? Kimberly Huber, PhD, is working long and hard in her lab to answer those questions. Dr. Huber, professor, Neuroscience, UT Southwestern Medical Center, is seeking to understand how FMRP regulates connections between brain cells, called synapses, and the function of brain circuits, which are several connected brain cells. Her current focus is the study of synapses and brain circuits in the mouse that mediate sensory perception, including perception of touch and sound. She aims to understand the cellular and molecular mechanisms by which loss of FMRP causes hyperexcitable sensory circuits. The goal: to develop targeted therapeutics that can restore normal brain function and reduce sensory hypersensitivity. “Sensory brain circuits are overactive, or hyperexcitable,Read more

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. “Biomarkers are key to learning more about their correlation with clinical and behavioral characteristics across diverse developmental stages in Fragile X syndrome,” said Dr. Cogram, the principal investigator of FRAXA’s Drug Validation Initiative (FRAXA-DVI) to test preclinicaly potential compounds for FXS. “We are searching for biomarkers that could potentially be used for clinical trials for treatment in children, teenagers, and adults with Fragile X.” Cue parents.

So ponders Cornell University researcher Samie R. Jaffrey, MD, PhD. Jaffrey, professor, Pharmacology, Weill Cornell Medical College, Cornell University, knows reactivating FMRP will lead to many important questions, such as: Which cell type needs FMRP? How much FMRP protein is needed to restore brain function? Where in the brain will FMRP protein be needed? Where in a neuron will the FMRP needs to be expressed? Will FMRP protein be created in the correct quantity and location to work as a therapeutic? In anticipationRead more

Dr. Maurin and Dr. Bardoni were awarded $90,000 over two years from FRAXA Research Foundation for their project, “Modulating cAMP And cGMP Levels As A New Therapeutic Approach For FXS”, in May 2016. They aim to gain a better understanding of how the brain develops and functions Like snowflakes, people with Fragile X Syndrome are not all alike. Some respond differently to the same drugs, as previous Fragile X research has shown. Understanding this phenomena is leading French scientists Barbara Bardoni, PhD, and Thomas Maurin, PhD, to identify new drugs to improve treatments in patients with Fragile X. Among the proteins they have identified, some are known to control brain function and development. This has helped identify a set of candidate proteins for which there are pre-existing active chemical compounds that target their activity. Using these compounds in vitro may revert some FXS hallmarks. “Access to different drugs will allow some flexibility inRead more
