Which of the available drugs are best for managing fragile X syndrome? Most drugs have “off-target” effects which can have key advantages in some cases.
First Healx secured $56M in new financing to launch a global Rare Treatment Accelerator program to tackle Fragile X syndrome and 39 other rare diseases. Now they have built a partnership with Boehringer Ingelheim worth millions. It all started with a small FRAXA grant to Healx to repurpose available drugs for Fragile X.
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.
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.
Dr. Anis Contractor and Dr. Qionger He investigated the potential of the available drug bumetanide to correct altered GABA signalling in a mouse model of Fragile X syndrome.
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.
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.
This work established a high-content synaptic imaging platform for Fragile X cells to test many candidate drugs for their ability to repair synapse structure and function.
Dr. Clinton Canal targets serotonin receptors to correct brain signaling in Fragile X, guiding drug discovery and repurposing of therapies for anxiety, seizures, and behavior.
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.
FRAXA Research Foundation awarded $122,000 to Dr. Cara Westmark at the University of Wisconsin at Madison for studies of sleep disorders in Fragile X syndrome.
Dr. Nahum Sonenberg’s research showed the diabetes drug metformin can correct key signaling defects in Fragile X, leading to clinical trials of this safe, repurposed therapy.
Dr. Lynn Maquat’s research shows Fragile X disrupts neuron maturation and RNA regulation, impairing brain signaling—pointing to new targets like NMD for drug development.
FRAXA has focused on identifying existing, approved drugs that could be repurposed for Fragile X, allowing potential treatments to move faster and at lower risk than starting from scratch. We’ve worked to advance the most promising candidates toward real-world use.
FRAXA awarded $44,000 to Healx for drug repurposing to find new treatments for Fragile X syndrome. The results include eight top "hits" which show promise for Fragile X.
FRAXA-funded research showed nonsense-mediated mRNA decay is overactive in Fragile X, pointing to existing NMD-suppressing drugs like caffeine as potential treatments.
CB1 blockade with rimonabant reversed cognitive, sensory, and seizure symptoms in FXS mice, highlighting the endocannabinoid system as a therapeutic target.
Dr. Wong studies how NMDA and mGluR receptors interact to trigger seizures in Fragile X, revealing NR2B-specific blockers as a promising targeted treatment.
