Considering Available Drugs for Fragile X: My Favorite Combination (So Far)
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.
New Partners Aim to Accelerate the Discovery and Repurposing of Medicines for Rare Neurological Diseases
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 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.
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.
Takeaways from Fragile X Advocacy Day
At my first Fragile X Advocacy Day, I met with Congress and families, advocating together for research and hope.
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.
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.
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.
Development of a High-Content Synapse Assay to Screen Therapeutics for Fragile X Syndrome
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.
Targeting Serotonin Receptors to Treat Behavioral and Psychological Symptoms
With a $90,000 grant from FRAXA Research Foundation awarded in 2017, Dr. Clinton Canal targets seratonin receptors. “There are 15 unique serotonin receptors (at least) and many of them impact the function of brain circuits that are impaired in neurodevelopmental and psychiatric disorders,” said Dr. Canal. “Results from this project could guide new drug discovery or drug repurposing for Fragile X.”
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.
Preclinical Testing of Sleep-Wake Patterns as an Outcome Measure for Fragile X
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.
Fragile X Nervous (System) Breakdown
“The occurrence and development of events by chance in a happy or beneficial way.” That’s how Lynne E. Maquat, PhD, describes the process of how her research extended to Fragile X syndrome to better understand it and ultimately find advanced treatments.
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.
University of Cambridge Startup Healx is Rapidly Identifying Existing Drugs to Help Fragile X Patients
FRAXA awarded $44,000 to Healx in 2017 for drug repurposing to find new treatments for Fragile X syndrome. The results of this study include eight top “hits” which show promise for Fragile X. FRAXA is further investigating these hits.
Repurposing Drugs to Dampen Hyperactive Nonsense-Mediated Decay in Fragile X Syndrome
FRAXA-funded research showed nonsense-mediated mRNA decay is overactive in Fragile X, pointing to existing NMD-suppressing drugs like caffeine as potential treatments.
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.
Boston Bruins Grant Funds New Fragile X Research
The Bruins Foundation pledged $90K to FRAXA, funding new Fragile X research at Gateway Farm in Merrimac, MA.
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.
Targeting the Endocannabinoid System in Adult Fragile X Mice
CB1 blockade with rimonabant reversed cognitive, sensory, and seizure symptoms in FXS mice, highlighting the endocannabinoid system as a therapeutic target.
Seizures in Fragile X Syndrome and Therapeutic Potential of NMDA Receptor Antagonists
Dr. Wong studies how NMDA and mGluR receptors interact to trigger seizures in Fragile X, revealing NR2B-specific blockers as a promising targeted treatment.
Social Behavior as an Outcome Measure for Fragile X Clinical Trials
FRAXA funding helped identify reliable social behavior tests in Fragile X mice and showed an mGluR5 treatment could improve sociability, guiding future trials.
