Neuren’s Tofinetide Successful in Phase 2 Clinical Trial in Fragile X
In this initial trial with a relatively short treatment period, trofinetide was very well tolerated, with the high dose (70 mg/kg twice daily) demonstrating a consistent pattern of clinical improvement.
CRISPR – Does it hold promise for Treatment of Fragile X Syndrome?
CRISPR offers the tantalizing possibility of “editing” genes precisely, and it could (theoretically) excise the methylated trinucleotide repeat sequence from Fragile X cells, returning them to normal.
FRAXADev – Developing BK Channel Openers for Fragile X Syndrome
FRAXADev is an initiative in France not connected with FRAXA Research Foundation. The name is coincidental. FRAXADev seeks to develop a new kind of drug for Fragile X.
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.
Analysis of Developmental Brain Dysfunction in Families
No strong behavioral similarities were found between parents and children with Fragile X, indicating family history may not guide clinical trial recruitment.
Crossroads of Fragile X and Alzheimers Research
Researchers at VIB Leuven in Belgium published evidence that a brain pathway involving the protein APP (Amyloid Precursor Protein) plays a vital role in development of Fragile X syndrome.
Fragile X: Past, Present, Future – Video
Michael Tranfaglia, MD, FRAXA Medical Director discussed how research has brought us to the point of clinical trials, the problems encountered in recent trials, and where we go from here.
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.
Boston Globe, “Playing a part in finding cure for Fragile X”
Fragile X is rare and not as highly publicized as many other better-known genetic diseases that attract media interest and generate richer revenue streams of giving. The world of the ailing doesn’t prioritize. There is no Find Help 101 manual for funding charities or what makes the public wake up one day and pour out its heart, empty its wallet, join a bike-a-thon for its cure.
Fragile X Treatment: New Research Directions
In the wake of negative results from several high-profile clinical trials in Fragile X, we find ourselves questioning many of our previous assumptions about the nature of this disorder.
Bryostatin Restores Learning and Memory in Adult Fragile X Mice
A marine critter found off the California coast — Bugula neritina — is the only source of Bryostatin. Bryostatin-1 restores spatial learning and memory in adult Fragile X mice.
Fragile X Programs at UMASS – University of MA, Worcester
Fragile X Syndrome Behavioral Health Clinic The Center for Autism and Neurodevelopmental Disorders (CANDO) is opening a specialty clinic for individuals with Fragile X Syndrome (under the direction of Dr. Jean Frazier) to evaluate and provide treatment for behavioral challenges.
The Endocannabinoid System in a Mouse Model of Fragile X Syndrome
Fragile X disrupts endocannabinoid signaling. This study in mice demonstrated that correcting it may calm brain hyperexcitability and improve symptoms.
Inhibitors of STEP as a Novel Treatment of Fragile X Syndrome
STEP inhibition reversed behavioral and synaptic Fragile X deficits in mice (Neuropharmacology, 2018), highlighting STEP as a promising treatment target.
Molecular Mechanisms of Cytoskeletal Regulation by FMRP
With FRAXA funding, Dr. Jaffrey linked FMR1 loss to abnormal dendritic spines via RhoA signaling, suggesting RhoA-targeted therapies could help treat Fragile X.
Students at WPI helping FRAXA Research Foundation
Two WPI student teams are working with FRAXA to improve our website and create a mobile app as part of their Interactive Qualifying Project.
NPR, “A Family’s Long Search For Fragile X Drug Finds Frustration, Hope”
There is no effective treatment for the rare genetic disorder Fragile X syndrome, so two parents created a foundation to fund research. But they found there’s no easy road to a cure. For a few weeks last year, Michael Tranfaglia and Katie Clapp saw a remarkable change in their son, Andy…
Neuren’s NNZ-2566 Shows Clinical Benefit in Rett Syndrome Trial
This isn’t a Fragile X trial, but the Neuren compound, NNZ-2566, that is in trials now for Fragile X has shown significant positive effects in a Phase 2 trial for Rett syndrome.
Clinical Trials Outcome Measures
There is a critical need for reliable biomarkers and clinical outcome measures for Fragile X syndrome. Treatment trials depend on this.
NIH Awards $35 Million to Three Fragile X Research Teams
NIH is investing $35M in three Fragile X Research Centers. All teams have been funded by FRAXA and will now receive over $2M annually for five years.
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.
