Repurposing Study II: Evaluating Combinations of Drugs to Treat Fragile X
FRAXA partnered with Healx to use AI to find approved drugs and drug combos that could treat Fragile X. Top candidates are now being tested in Fragile X models.

Impact of the Fragile X Community
Because of you, FRAXA invests $1M+ each year in Fragile X research and helped launch $35M more in studies leading to clinical trials.
Fragile X Clinical Trial of AZD7325 in Adults
FRAXA funded a trial of AZD7325, a drug that boosts GABA(A), in adults with Fragile X. Led by Dr. Craig Erickson, it also tested innovative biomarkers for future trials.

CRISPR Reactivation of the Fragile X Gene
“We are trying to target the first event that goes wrong in Fragile X syndrome”, says Todd, “One reason our previous attempts to develop treatments for Fragile X syndrome have failed is that they’ve tried to target the downstream effects of losing the Fragile X protein. The protein does many things… bypassing all the functions that it normally takes care of has proven difficult from a pharmacologic perspective.”
$17,469 Raised by Friends of FRAXA Volunteers at Bruins Game
Over 50 #FriendsofFRAXA volunteers sold $34,938 in 50/50 raffle tickets at the Bruins game—raising $17,469 for Fragile X research!

Coming Full Circle – Kathy May Returns back to FRAXA
After 20 years, FRAXA co-founder Kathy May returns, saying, “There will be a cure. FRAXA is the reason for this hope.”
Newly Discovered Regulatory Pathways in Fragile X
Studies at Yale University and elsewhere are showing that FMRP plays a significant role in the regulation of potassium channels. Looking forward, potassium channel opener drugs could rescue some symptoms of Fragile X in humans.
Drug Repurposing Study Results Accelerate Progress Towards Fragile X Treatments
While there are over 8,000 rare diseases affecting an estimated 350 million people worldwide, only around 200 of these conditions have effective treatments. Due to the high cost of developing new drugs, rare diseases have historically been less attractive to pharmaceutical companies. Drug repurposing systematically leverages the detailed information available on approved drugs and reduces the time and money needed to deliver safe “new” treatments, but with greater success rates and a potentially more immediate impact on health care.
Brain Imbalance Target of Dr. Erickson’s New Clinical Trial
Dr. Erickson’s trial targeted brain imbalance in Fragile X by boosting GABA signaling with AZD7325, aiming to restore excitatory–inhibitory balance and improve symptoms.
Fragile X in the Forefront of International Conference
The 18th International Fragile X Workshop kicks off in Quebec, uniting global scientists to share breakthroughs in Fragile X and ASD.
Quantitative Assessment of the Serotonin System in a Mouse Model of Fragile X Syndrome
FRAXA funded Dr. Canal to investigate how different serotonin receptors function in Fragile X, to guide smarter use of serotonin-targeting treatments.
Targeted Transcriptional Reactivation of FMR1 in Fragile X Syndrome Stem Cells
FRAXA funded Dr. Peter Todd to use CRISPR to reactivate FMR1. Published results confirmed restored gene expression, a big step toward disease-modifying therapy.
Defining Subcellular Specificity of Metabotropic Glutamate Receptor (mGluR5) Antagonists
This study showed that selectively targeting mGluR5 receptors in specific neuronal compartments can correct distinct Fragile X synaptic defects, improving precision therapy.
Investigating Gene Reactivation to Treat Fragile X Syndrome
With a $180,000 grant from FRAXA Research Foundation, Dr. Jeannie Lee and her team at Harvard are working to reactivate the gene that is silenced in Fragile X syndrome.
Mechanisms of Tolerance to Chronic mGluR5 Inhibition
FRAXA supported research showing mGluR5 antagonist tolerance develops quickly in Fragile X models, guiding new strategies to prevent or overcome it.
Prefrontal Cortex Network (PFC) Dynamics in Fragile X Syndrome
With a $90,000 grant from FRAXA Research Foundation from 2016-2017, Dr. Daniel Johnston and Dr. Jenni Siegel at the University of Texas at Austin are analyzing pre-frontal cortex (PFC) dysfunction in the Fragile X model. They have preliminary evidence that Fragile X mice are severely impaired in a prefrontal cortex (PFC)-dependent task.
