Tetra Therapeutics has launched large scale clinical trials of their phosphodiesterase (PDE) inhibitor for males ages 12-45 with Fragile X syndrome. FRAXA Research Foundation’s basic and translational research pointed the way to phosphodiesterase inhibitors to treat Fragile X.
Read moreTargeting Cognitive Function in Fragile X Syndrome

It has long been assumed that the differences between males and females with Fragile X were simply a matter of degree, with males being more severely affected. But gender differences may be far reaching. This team is working to understand imbalances in how the brain’s neurons transmit signals, with a focus on how differently males and females learn and experience anxiety. They are studying two neuronal pathways which are promising targets for treatment.

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.
Read moreAstrocyte Contribution to Sensory Hypersensitivity in Fragile X Syndrome

Most Fragile X research has focused on one type of brain cells: neurons. But mounting evidence point to problems with astrocytes, star-shaped cells which are vitally important to normal brain function. This team is working to understand how astrocytes are involved in Fragile X and develop treatment approaches that targets astrocytes alone.
Read moreDevelopmental Motor Phenotype in Fragile X Syndrome

One of the lesser known signs of Fragile X is unsteady walking. This is also very easy to evaluate in the clinic: no blood tests are required! With a $100,000 grant from FRAXA Research Foundation, this team will develop objective new outcome measures of gait for future treatment trials and also to see if exercise could improve other symptoms of Fragile X.
Read morePharmacological 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.
Read moreSigma-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.
Read moreFragile 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.
Read moreVersatile 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.
Read moreHuman 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?
Read moreFunctional 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.
Read moreReactivating the FMR1 Gene to Reverse Fragile X Syndrome

FRAXA has awarded $140,000 to Dr. Jeannie Lee and Dr. Hungoo Lee at Harvard Medical School and Massachusetts General Hospital. This team is targeting the root cause of Fragile X syndrome: a silenced single gene, called FMR1.
Read moreTargeting 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.
Read moreTranscriptional 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.
Read moreCharacterization 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.
