FRAXA Drug Validation Initiative (FRAXA-DVI)
The FRAXA Drug Validation Initiative (FRAXA-DVI) provides speedy, cost-effective, objective preclinical testing to validate investigational and repurposed compounds for Fragile X.
Metabolic and Mitochondrial Crosstalk in Insulin and cAMP Pathways in Fragile X Syndrome
Fragile X syndrome research explores insulin and cAMP pathway crosstalk, mapping brain metabolism to guide treatment strategies.
2021 Fragile X Research Grants Funded by FRAXA Research Foundation
Each year, FRAXA funds a diverse portfolio of research. Our FRAXA Fellowships are seed funding for the future, the feedstock for the Fragile X treatment development pathway. While we are looking to promote as many promising new approaches as possible, prominent themes emerge each year, as scientists around the world tackle previously neglected areas.
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.
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
Drug Repurposing for Rare Disease and the Future of Health – The Genetics Podcast
In this double-bill episode of The Genetics Podcast, Dr. Patrick Short talks to two key rare disease researchers in the field: Dr. Bruce Bloom, CCO of Healx, and Dr. Mike Tranfaglia, CSO of FRAXA. Both draw on their wide-ranging personal and professional experiences to discuss the successes and opportunities of drug repurposing, the power of using machine learning, and the work they’ve been doing to aid in finding effective treatments for Fragile X.
Targeting Adiponectin to Treat Fragile X Syndrome
Boosting adiponectin, a hormone that regulates metabolism, may improve cognition and behavior in Fragile X. Early results suggest it can restore brain plasticity.
Healx Raises $56M to use AI to Find Treatments for Fragile X & Other Rare Diseases
Healx has secured $56M in new financing to build a clinical-stage portfolio for rare diseases, including treatments for Fragile X syndrome, and to launch a global Rare Treatment Accelerator program. Where the traditional drug discovery model takes more than a decade and can run into the billions of dollars, Healx’s AI-driven approach makes the process faster, more efficient and cost-effective.
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.
Screening 2,320 FDA-Approved Drugs for Potential Treatment of Fragile X
FRAXA funded a screen of 2,320 FDA-approved compounds in the Fragile X fly model to identify hits that improve memory and social behavior for advanced testing.
Metformin and Aberrant Insulin Signaling in a Fragile X Mouse Model
FRAXA-funded research is revealing how insulin signaling is altered in Fragile X and whether lowering it, including with metformin, could ease symptoms.
In Their Own Words: Reports From the International Fragile X Workshop
The 18th International Fragile X Workshop in Quebec was a great success, featuring more Fragile X research than ever before!
FRAXA Wins Award for Drug Repurposing
Cures Within Reach, the leading global nonprofit focused on repurposing research as a fast track to saving patient lives, has awarded FRAXA Research Foundation the 2017 Golan Christie Taglia Patient Impact Philanthropy Award for efforts to find treatments for the rare disease Fragile X syndrome.
Metformin, Diabetes Drug, Potential Fragile X Treatment
"We treated mice with metformin and corrected all the core Fragile X deficits. We are optimistic about using metformin in human clinical trials. This is a generic drug with few side effects" says Nahum Sonenberg, PhD, James McGill Professor, Department of Biochemistry, McGill Cancer Center, McGill University.
Repurposing Available Drugs to Treat Fragile X Syndrome – FRAXA Initiatives
FRAXA Research Foundation was founded in 1994 to fund biomedical research aimed at finding a cure for Fragile X syndrome and, ultimately, autism. We prioritize translational research with the potential to lead to improved treatments for Fragile X in the near term. Our early efforts involved supporting a great deal of basic neuroscience to understand the cause of Fragile X. By 1996, these efforts had already begun to yield results useful for drug repurposing. To date, FRAXA has funded well over $25 million in research, with over $3 million of that for repurposing existing drugs for Fragile X.
Fragile X Fruit Fly Research Bears Fruit
A new FRAXA-funded study shows how the hormone insulin – usually associated with diabetes — is involved in the daily activity patterns and learning deficits in the fruit fly model of Fragile X Syndrome (FXS). The study also reveal a metabolic pathway that can be targeted by new and already approved drugs to treat Fragile X patients, notably metformin.
Targeting AMP-Activated Protein Kinase Pathway in Fragile X Syndrome
With this grant from FRAXA, Dr. Peter Vanderklish explored AMPK activators to treat Fragile X. Both metformin and resveratrol, found in red wine, are AMPK activators.
Fruit Flies to Model and Test Fragile X Treatments
Boosting cAMP signaling restores memory and fixes brain-signaling defects in Fragile X models, suggesting diabetes drugs like metformin may help.
Effects of Metformin in Fmr1 Knockout Mouse Model of Fragile X Syndrome
Metformin, a safe diabetes drug, activates AMPK to rebalance protein synthesis. FRAXA-funded work investigated its potential to treat Fragile X.
