How Does FRAXA Help?
FRAXA’s mission is to find effective treatments and ultimately a cure for Fragile X syndrome. We directly fund research grants and fellowships at top universities around the world. We partner with biomedical and pharmaceutical companies, large and small, to bridge the gap between research discoveries and actual treatments.
Treatments for Fragile X are likely to help people affected by autism, Alzheimer’s, and other brain disorders.
What is Fragile X Syndrome?
Fragile X syndrome (FXS) is the most common inherited cause of autism and intellectual disabilities. It affects 1 in 4,000 boys and 1 in 8,000 girls worldwide.
Fragile X syndrome occurs when a single gene on the X chromosome shuts down. This gene makes a protein needed for normal brain development. In FXS it does not work properly, the protein is not made, and the brain does not develop as it should.

Fragile X Clinical Trial: Novartis Trial Results Are In, and They’re Not Pretty
This year’s Gordon Conference just finished, and Novartis presented their results for the first time (though advisors and advocates had been given a private peak months ago.) To say that the trial results for AFQ056 were disappointing would be the understatement of the century!

Novartis has announced that the company will be discontinuing its development program in Fragile X for its lead mGluR5 antagonist, mavoglurant (AFQ056), following negative results in a large international clinical trial in adults (reported in the Fall of 2013) and most recently, in a trial in adolescents. In both placebo-controlled trials, patients taking mavoglurant did not show improvement over placebo in any outcome measures. Novartis has also announced that the current open-label extension phase of the trial will be closed, but patients will be allowed to continue on the medication until their next scheduled clinic visit, or August 29, whichever comes first.

Researchers led by Dr. Karen O’Malley at Washington University School of Medicine in St. Louis have published results of their work on mGluR5 and Fragile X syndrome. FRAXA Research Foundation provided funding for this work from 2009 until 2013. Pharmaceutical companies have developed therapeutic compounds to decrease signaling associated with the mGlu5 receptor, moderating its effects on brain cells’ volume knobs. But the compounds were designed to target mGlu5 surface receptors. In light of the new findings, the scientists question if those drugs will reach the receptors inside cells.

Many older family members in the Fragile X community are affected by FXTAS (Fragile X-associated Tremor/Ataxia Syndrome). We all hope that knowing the underlying cause of neurodegenerative symptoms in FXTAS will help in the development of specific treatments over the long term. In the short term, we would also hope that having a specific diagnosis would help us to identify particular available treatments which might be more effective than others.

Scientists Uncover Trigger for Fragile X Syndrome
A new study led by Weill Cornell Medical College scientists shows that Fragile X syndrome occurs because of a mechanism that shuts off the gene associated with the disease. The findings, published today in Science, also show that a compound that blocks this silencing mechanism can prevent Fragile X syndrome – suggesting a similar therapy may be possible for 20 other diseases that range from mental retardation to multisystem failure.

Small Molecules To Target r(CGG) Expansions to Treat Fragile X Syndrome
With a 2-year, $90,000 grant from FRAXA Research Foundation, Dr.’s Matthew Disney and Wang-Yong Yang worked to correct the underlying problem in Fragile X: the silencing of the Fragile X gene (FMR1) and the resulting lack of FMRP (Fragile X Mental Retardation Protein). Their approach was to use novel small molecules to target the abnormal CGG repeats before the FMR1 gene.
