Astrocytes are star-shaped cells that make up one fifth of all cells in the human brain. Recently researchers found a specific pathway in astrocytes that is overactive in Fragile X syndrome, and they hope to bring this pathway back to normal with a drug. With this grant, the team will try to correct the pathway in Fragile X mice. The hope is that they will find a new potential treatment approach for Fragile X syndrome.

Drug Tolerance in MGluR5 Clinical Trials – Dr Patrick McCamphill 1:1 with FRAXA
We have long suspected that the clinical trials of mGluR5 blockers from Novartis and Roche failed because the drug triggered tolerance, losing effect over time. With a $90,000 grant from FRAXA, Dr. Patrick McCamphill, a Postdoctoral Fellow in the MIT lab of Dr. Mark Bear, is investigating. He does indeed find tolerance, and now he is looking for ways to overcome it.

Pivotal Phase 3 Trial of Zygel in Severe Fragile X Possible This Year
Zynerba Pharmaceuticals reported receiving advice from the U.S. Food and Drug Administration (FDA) on the design of an upcoming Phase 3 clinical trial meant to confirm previous trial findings supporting Zygel as a cannabidiol treatment in a specific subset of Fragile X syndrome patients. The new trial, called RECONNECT, is expected to launch before October, and will mainly enroll children and adolescents with a complete (100%) methylation of FMR1, the gene mutated in Fragile X.

FRAXA Drug Validation Initiative (FRAXA-DVI)
The FRAXA Drug Validation Initiative (FRAXA-DVI) provides speedy, cost-effective, objective preclinical testing of potential Fragile X treatments. FRAXA-DVI uses in-vitro systems, behavior batteries, and gene expression and peripheral biomarker platforms to validate investigational new drugs and repurposed available compounds in Fragile X syndrome (FXS).

Pharmacotherapeutic Effects of Cannabidiol (CBD) in Fragile X syndrome (FXS) and Autism Spectrum disorder (ASD)
This study will test CBD (cannabidiol) treatment in male and female Fragile X mice to learn how and why it works and whether gender affects responses to CDB treatment. Along with clinical trials, this study will help us to understand and optimize the potential of CBD as a behavior-regulating treatment for Fragile X.

NPR Short Wave, “A Fragile X Treatment May Be On The Horizon”
Katie Clapp and Michael Tranfaglia’s son was born with a genetic disorder that affects brain development. It makes it hard to learn language and basic daily tasks and often is accompanied by a host of other disorders. To help find a cure, they started a foundation and raised research money. After se…

Tetra Releases Full Results of FRAXA-Funded Clinical Trial of PDE4D Inhibitor
Today, Tetra Therapeutics published the full results of its PDE4D trial published the full results to their announcement. Now having reviewed the full results, FRAXA can confidently say that the PDE4D drug trial gives hope to patients and families that Fragile X Syndrome is a treatable disorder, and this particular drug can improve intellectual disability.

Cellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome
Studies have shown that the function of inhibitory networks is disturbed in Fragile X. This abnormality is not well understood but appears to be secondary to abnormalities in metabotropic glutamate and endocannabinoid systems. With a $90,000 grant from FRAXA, Dr. Molly Huntsman’s team examined how these networks interact and how inhibitory deficits can best be remedied.

Auditory Dysfunction in Fragile X Syndrome in a Mouse Model of Fragile X
With a $90,000 grant from FRAXA, Dr. McCullagh and Dr. Achem Klug at the University of Colorado investigated whether auditory neural circuits are altered in Fragile X mice. They saw minor differences in these mice compared to B6 (control) mice in several measures of auditory acuity. Fmr1 mice had increased latency to the startle response for almost all conditions compared to B6 mice, suggesting altered timing to acoustic cues. These experiments show that, consistent with patient reports and anatomical/physiological data, the auditory system is altered in a mouse model of FXS, though with some potential compensation leading to a subtle behavioral impact.

Parkinson’s Therapy May Hold Promise for Fragile X
A study funded by FRAXA in Italy has encouraging results for people with Fragile X: drugs that block adenosine receptors (A2A) reversed signs of Fragile X in a mouse model.
“One of the most intriguing things about this study is that it points to an entire drug class (not just the one drug used) as potentially therapeutic for Fragile X. Many available compounds block A2A receptors, and we know they are safe and effective.

Beneath the Surface of Fragile X Syndrome: Study Sheds Light on What’s Happening in Nerve Cells
This FRAXA-funded project has turned up some surprising results. At first, it might seem Kurosaki and Maquat have found yet another cellular process which is malfunctioning in Fragile X. But this finding is intimately related to previous findings of abnormal protein synthesis and misregulated transcription in Fragile X. FMRP (the protein lacking in Fragile X syndrome) is involved in chaperoning messenger RNAs within cells to active sites, and in controlling their translation into many different proteins. Some of these proteins are transcription factors, which feed back to the nucleus to control gene expression.
