Neurolixis’ new drug targets serotonin 1A receptors, showing promise in preclinical studies for Fragile X syndrome, funded by a FRAXA grant for future clinical trials.
10 Year Vision for Fragile X Research – Dr. Elizabeth Berry-Kravis & Dr. Patricia Cogram
In this video we hear from FRAXA Investigators Dr. Patricia Cogram, Professor at the University of Chile, and Dr. Elizabeth Berry-Kravis, Professor at Rush University Medical Center as they reflect on the progress that has been made and visualize what they see happening in the next 10 years for people living with Fragile X syndrome.
Developmental Motor Phenotype in Fragile X Syndrome
A little known sign of Fragile X is unsteady walking. This is very easy to evaluate in the clinic: no blood tests required! This team is developing outcome measures of gait for future treatment trials.
Sigma-1 Receptor as a Therapeutic Target for Fragile X Syndrome
Dr. Pouladi’s team is exploring a treatment of Fragile X via the sigma-1 receptor. Drugs that boost activity at sigma receptors tend to calm down overactive neurons. They are also powerful anti-inflammatory drugs.
Fragile X Clinical Trial of New PDE4D Inhibitor from Tetra
With a $200,043 grant from FRAXA Research Foundation, Dr. Elizabeth Berry-Kravis completed a successful Phase 2 clinical trial of a PDE4 inhibitor for adult men with Fragile X syndrome. This trial treated 30 males, 18-45 years of age with a new PDE4D allosteric inhibitor from Tetra Discovery Partners using a crossover design, so that everyone got active drug for part of the time and placebo for part of the time.
Versatile Drug Screening Platform for Fragile X Syndrome
Many experts believe that combinations of drugs may be needed to best treat Fragile X syndrome. How can we find the best combinations in the ideal doses? This project — a collaboration between a top university research team and an innovative AI startup both based in Belgium — tackles this challenge.
Human FMR1 Isoform-Specific Regulation of Translation and Behavior
Fragile X syndrome is caused by lack of one protein, FMRP. But this one protein occurs in different variations. Do the different versions of FMRP have different roles in the brain, and if so, is there one that’s key? If we could replace FMRP to treat Fragile X syndrome, which version would we use?
Functional and Genomic Characterization of Interneurons in the Fmr1-KO Mouse Brain
The brain’s balance is maintained by two types of neurons: those that excite and those that inhibit activity. Like yin and yang, this balance is essential. This team has found fewer than normal inhibitory cells in the brains of Fragile X mice. They are now working to pinpoint this abnormality and find ways to restore the normal balance and function.
Targeting Serotonin 1A Receptors in Fmr1 Knockout Mice
Dr. Canal has discovered a promising treatment approach for Fragile X syndrome: new compounds which specifically and potently boost serotonin in the brain. The target is the brain’s serotonin 1A receptor.
Transcriptional Signatures Sensitive to Cognition-Improving Pharmacological Treatments in Fragile X Syndrome
The Fragile X field needs biomarkers to accurately measure the effects of potential treatments in both Fragile X mice and in humans. Dr. Ozaita and his team have found molecular features in the brain that can serve as an objective signature for the syndrome. They will use this tool to test cannabidiol and two other drugs in mice.
Characterization and Modulation of microRNAs in Fragile X Syndrome
Could microRNAs be a new path to treatment of Fragile X syndrome? MicroRNAs are disrupted in Fragile X, and so this team will work to understand what is going wrong and explore ways to correct it with drugs which directly target microRNAs.
Repurposing FDA-Approved Drugs to Treat Major Depressive Disorder in Fragile X Syndrome
Did you know that depression is more common in those with autism and/or Fragile X? Even more disturbing is the discovery that current treatments for depression do not work in Fragile X mice. With this grant, the team will work to develop a rapid screening tool to identify FDA-approved drugs which can treat depression in people with Fragile X syndrome.
mRNA Therapy for Fragile X Syndrome
Dr. Kathryn Whitehead, Associate Professor at Carnegie Mellon University, helped develop the revolutionary science behind the COVID-19 vaccines. With a $103,000 grant from FRAXA, her team will now adapt this technology to deliver the missing Fragile X protein, to treat people who have Fragile X syndrome.
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.
Recruiting: Clinical Study of Non-Invasive EEG for Children Ages 2-7
Dr. Carol Wilkinson, MD PhD, and Dr. Charles Nelson, PhD, at Boston Children’s Hospital are recruiting children ages 2-7 years with Fragile X syndrome to participate in a study of brain differences using non-invasive EEG.
