FX-Learn Clinical Trial for Children with Fragile X
Thirteen centers across the US enrolled young children with Fragile X in a large-scale clinical trial of Novartis AFQ056, an mGluR5 blocker for Fragile X which failed in adult human trials.
Cannabinoids as a Treatment for Fragile X Syndrome
This team uses EEG to study sensory hypersensitivity in Fragile X. By testing drugs in mice, they aim to find treatments that calm brain overactivity.
Clinical Trial of Metformin for Fragile X Syndrome
FRAXA-funded open-label trial found that metformin led to increased GABA-mediated cortical inhibition, suggesting metformin modulates core Fragile X pathways.
Purposeful and FRAXA Partnership Leads to Clinical Trial
AI and FRAXA-DVI identified a drug + supplement combo that reversed all Fragile X symptoms in mice. A clinical trial tested this in adults with Fragile X.
Inhibiting Nonsense – Mediated mRNA Decay: A Potential Treatment Approach for Fragile X
This team previously discovered runaway nonsense-mediated mRNA decay (NMD) in cells of Fragile X patients. They will now test drugs to reduce NMD.
Exploring Drug Repurposing to Restore Hippocampal Function in FXS Mouse Models
This team found a key mechanism by which FMRP controls brain connections. They’ll test existing drugs that target this pathway to restore learning and memory in Fragile X.
Contribution of Microglia to the Therapeutic Effects of Metformin and Adiponectin in Fragile X Syndrome
Why are some with Fragile X always hungry or overweight, yet rarely diabetic? This team is studying metabolism and testing treatments like metformin and diet.
Alternative Splicing in White Blood Cells: A Biomarker for Fragile X Syndrome
This team found 1,600 blood-based Fragile X biomarkers that vary by individual—opening the door to personalized treatment and better ways to measure progress.
Link Between Lipid Profile, eCBome System and Gut Microbiome in Fragile X Syndrome
Why does obesity challenge so many people with Fragile X? Dr. Caku’s team has found that Fragile X syndrome causes changes in the tiny organisms that live in our gut.
Characterization of Microglia Transcriptional Profile in Fmr1 Knockout Mice Model
Microglia are excessively activated in Fragile X models. The team will investigate the mechanisms and attempt to correct this using drugs.
The Role of Astrocyte BMP Signaling in Fragile X Syndrome
Researchers found a pathway in astrocytes that is overactive in Fragile X syndrome, and they hope to bring this pathway back to normal with a drug.
Identifying Cellular and Molecular Signatures in Human Neurons That Distinguish Fragile X Syndrome Patients with Divergent EEG Profiles
Just as Fragile X affects individuals differently, medications do as well. This project aims to bring personalized medicine to Fragile X syndrome.
Drug Tolerance in MGluR5 Clinical Trials – Dr Patrick McCamphill 1:1 with FRAXA
We suspected that clinical trials of mGluR5 blockers from Novartis and Roche failed because the drug triggered tolerance. Dr. Patrick does find tolerance, and is looking for ways to overcome it.
Pharmacotherapeutic Effects of Cannabidiol (CBD) in Fragile X syndrome (FXS) and Autism Spectrum disorder (ASD)
This study tested CBD (cannabidiol) treatment in male and female Fragile X mice to learn how and why it works and whether gender affects responses to CDB treatment.
Cellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome
The team studied how inhibitory brain circuits malfunction in Fragile X and tested ways to restore balance by targeting mGluR and endocannabinoid signaling.
Auditory Dysfunction in Fragile X Syndrome in a Mouse Model of Fragile X
FRAXA-funded studies found Fragile X mice show altered auditory circuit function with delayed startle timing and reduced prepulse inhibition, mirroring human sound sensitivity.
Beneath the Surface of Fragile X Syndrome: Study Sheds Light on What’s Happening in Nerve Cells
Lynne Maquat discovered that many irregularities in cells that lack FMRP are due to misregulated nonsense-mediated mRNA decay, or NMD. Results published.
Genome-wide Screen for FMR1 Reactivation in Human FXS Neural Cells
This team aims to turn the FMR1 gene back on in Fragile X by identifying factors that reactivate the silenced gene and restore production of the missing FMRP protein.
MicroRNAs as Biomarkers in Fragile X Syndrome
The team at Johns Hopkins University studied groups of small RNAs, known as microRNAs, which are greatly decreased in brain tissue of Fragile X mice vs. normal controls.
Auditory System Dysfunction and Drug Tolerance in the Fragile X Mouse
A $90K FRAXA grant will help uncover why Fragile X causes sound hypersensitivity and test ways to correct brain circuit dysfunction linked to auditory overload.
MicroRNA Mediated Astroglial GLT1 Dysregulation in Fragile X
The team studied how glial cells, especially astrocytes, affect Fragile X. They tested microRNAs to restore GLT1 and reduce excess glutamate linked to brain hyperexcitability.
Cholesterol-Dependent Changes in Fragile X Astrocytes
Astrocytes and cholesterol metabolism are altered in Fragile X. This research uncovers how these changes affect the brain and may reveal new treatment targets like lovastatin.
Ketogenic Diet Eases Symptoms in Fragile X Male Mice
Westmark Lab is studying sleep patterns in Fragile X mice, working with UW-Madison to develop tools that speed EEG data analysis
Results Reported: Using EEG Responses to Sound for Fragile X Drug Discovery
An obstacle in FXS research has been lack of reliable, unbiased biomarkers to assess herapies. This team found striking similarity in EEG biomarkers between mice and humans.
