Recruiting: BRIDGE Study (BRain Indicators of Developmental Growth)

Recruiting: BRIDGE Study (BRain Indicators of Developmental Growth)

This study from the Wilkinson Lab at Boston Children’s Hospital is investigating how differences in brain activity affect learning, language and behavior in children with Fragile X syndrome, Down syndrome, and Autism Spectrum Disorder. One of the goals is to find brain markers that predict cognitive, language, and behavioral difficulties in these groups. Another goal is to better understand the differences in brain activity between young children with and without Fragile X and Down Syndrome, and whether these differences are similar in children with Autism Spectrum Disorder.

Cannabinoids as a Treatment for Fragile X Syndrome

Cannabinoids as a Treatment for Fragile X Syndrome

Many people with Fragile X syndrome are hyper-sensitive to sights and sounds, and Electroencephalography (EEG) studies show that there are abnormalities in brain circuits. EEG studies show similar changes in Fragile X mice. So the team will use EEG tests in mice to find which drugs best reduce hypersensitivity. They can then easily move on to human EEG-based clinical trials. What they learn will tell us much more about why people with Fragile X are hypersensitive – and which drugs could best help them.

Results Reported: Using EEG Responses to Sound for Fragile X Drug Discovery

Results Reported: Using EEG Responses to Sound for Fragile X Drug Discovery

Jonathan Lovelace, a FRAXA funded Postdoc at UC Riverside, has made some exciting EEG findings over the past few years studying auditory hypersensitivity in mice and therapeutic drug treatments. A big obstacle in FXS research has been establishing reliable, unbiased, and translation relevant biomarkers that can be used to determine the effectiveness of therapies. One of the most important discoveries they have made is the striking similarity in EEG biomarkers between mice and humans.

Pharmacological Modulation of Nicotinic Signaling

Pharmacological Modulation of Nicotinic Signaling

Nicotine — familiar to any smoker — tickles nicotinic acetylcholine receptors in the brain. These receptors are key to important brain functions including learning and memory. This team will explore whether drugs that dampen these receptors can improve cognitive function in Fragile X.

The FRAXA Drug Validation Initiative (FRAXA-DVI) provides speedy, cost-effective, objective preclinical testing of potential Fragile X treatments. FRAXA-DVI uses in-vitro systems, behavior batteries, and gene expression and peripheral biomarker platforms to validate investigational new drugs and repurposed available compounds in Fragile X syndrome (FXS).

Kimberly Huber, PhD, Explores Hyperexcitability in Fragile X Syndrome

Kimberly Huber, PhD, Explores Hyperexcitability in Fragile X Syndrome

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.

In Their Own Words: Reports From the International Fragile X Workshop

In Their Own Words: Reports From the International Fragile X Workshop

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, with brief updates from researchers investigating Fragile X.

Overcoming the Placebo Effect in Fragile X Clinical Trials

Overcoming the Placebo Effect in Fragile X Clinical Trials

In a placebo-controlled clinical trial, some participants are given an experimental medication, while others are given a placebo. Participants do not know whether they are taking medicine or placebo. In theory, this can allow researchers to rule out the placebo effect by comparing outcomes among the two groups. But, per Wexler (2020) “having a strong placebo effect can obscure any real effect of the therapy being investigated”.

Clinical Trials in Fragile X Syndrome

Clinical Trials in Fragile X Syndrome

Each study is supervised by a doctor that specializes in Fragile X. These trials are free, you do not have to tell your insurance company, and you can leave any time you want. Travel costs are usually covered.

The FDA requires two successful large-scale clinical trials before it will consider approving a new treatment. If studies are successful and the FDA approves new drugs, others with Fragile X can also have access to these medicines.

Finding Fragile X Biomarkers – From Transcriptomics to Behavior in Patients

With this $20,000 award from FRAXA Research Foundation, Dr. Vanderklish and collaborators at Scripps Research Institute, the University of Chile, and the FLENI Institute in Argentina are analyzing patterns in gene expression in blood cells of patients with Fragile X syndrome. They are using “transcriptomics” which can produce a time-sensitive signature of an individual person. This is the first time that all these different levels of study – from transcriptomics to behavior – have been done for individual patients with Fragile X.

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

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.
