Finding a Cure for Fragile X
Each year, FRAXA funds a diverse portfolio of research. Our FRAXA Fellowships are seed funding for the future, the feedstock for the Fragile X treatment development pathway. While we are looking to promote as many promising new approaches as possible, prominent themes emerge each year, as scientists around the world tackle previously neglected areas.

FRAXA Research Foundation has awarded $45,000 to Dr. Maija Castrén, of the University of Helsinki, Finland. Dr. Castren is working with Dr. Iryna Ethell, at the University of California at Riverside, to uncover mechanisms behind beneficial effects of lovastatin and cholesterol-dependent changes seen in the Fragile X brain.

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.

Administering a cholesterol drug alongside an antibiotic eases atypical behavior and restores the signaling balance in the brains of people with fragile X syndrome.

Many drugs for fragile X syndrome have failed in large clinical trials, but candidates that target new aspects of the condition may fare better.

With a $66,714 grant from the FRAXA Research Foundation awarded over 2015-2017, Dr. Francois Corbin at the Universite of Sherbrooke will test the safety and synergistic effects of lovastatin and minocycline in patients with Fragile X syndrome.

Over the past few years, both Novartis and Roche sponsored large-scale clinical trials of metabotropic glutamate receptor 5 (mGlu5) negative allosteric modulators (NAMs) to treat Fragile X syndrome (FXS). With a $90,000 grant from FRAXA Research Foundation in 2015-2017, Dr. Mark Bear’s team will explore if mGlu5 NAMs dosed chronically causes tolerance, and if so, how it develops and to probe new avenues to prevent or circumvent it.

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.

FRAXA Research Foundation funded a 2016-2017 Fellowship for Dr. Stephanie Barnes in the University of Edinburgh lab of Dr. Emily Osterweil. With this $90,000 award, the team is investigating NMDA signaling in fragile X syndrome mice.

If all the science world’s a stage, Fragile X researchers are more than merely players. They are center stage. So believes Francois Corbin, MD, PhD, professor, Université de Sherbrooke, Canada, who directs the university’s Fragile X Clinic. Corbin, who has received more than $100,000 in FRAXA support since 2012, is leading a pilot randomized Phase II trial, exploring the tolerability and the synergistic effect of a combined therapy.

Dr. Emily Osterweil was awarded the FRAXA Pioneer Award at the opening dinner of the 2011 FRAXA Investigators Meeting in Southbridge, MA for her work demonstrating that Lovastatin could treat Fragile X. Dr. Osterweil conducted her experiments in the MIT laboratory of Dr. Mark Bear and has since established her own laboratory at the University of Edinburgh. The team discovered that lovastatin, a drug widely prescribed for high cholesterol, can correct excess hippocampal protein synthesis in the mouse model of FXS and can prevent epileptogenesis. The work is published in the prestigious neuroscience journal Neuron: Lovastatin Corrects Excess Protein Synthesis and Prevents Epileptogenesis in a Mouse Model of Fragile X Syndrome.

With $384,345 in grants from FRAXA Research Foundation, Dr. MariVi Tejada from the University of Houston focused on a particularly promising point of intervention in pathways of brain receptors, and tested several potential therapeutic compounds in an attempt to rescue function in the mouse model of Fragile X.
