Support the Stevenson Family Campaign
As we tentatively and joyfully begin to emerge from the recent health crisis, it’s awe-inspiring to reflect on how we’ve all benefited from the world’s top scientists coming together to develop vaccines and treatments for COVID-19. That same passion for innovative science motivates us now more than ever to support brain research that could dramatically improve the lives of those coping with Fragile X syndrome.

The research team of Brian Christie, PhD and Marie-Eve Tremblay is developing ways to balance hormones, including drugs like metformin and changes in diet, which could not only reduce hunger and obesity, but ultimately also improve learning and behavior in Fragile X syndrome.
Read moreBrain Organoids, Moving Fragile X Research Forward
There are many ways research produces discoveries, and all of them include a process of steps that build on each other. When an exciting new avenue appeared with potential for Fragile X syndrome, FRAXA stepped up to fund it. We now see the results of this grant and are excited to share them with you. The importance of different types of models have been shared and discussed over many years. We are now adding a “brain organoid” model to this group, and the potential behind it is really exciting.

One of the most exciting kinds of work that FRAXA does is following the journey of an experimental new treatment until it is ready for trials in people with Fragile X. From an initial idea, through the development process, to clinical trials, FRAXA helps out all along the way. From an initial idea, through the development process, to clinical trials, FRAXA helps out all along the way. The recent announcement by Synaptogenix is a great example of how FRAXA funding and use of FRAXA-DVI can accelerate research on Fragile X.

Read morePositive Results Reported in Phase II Fragile X Clinical Trial of PDE4D Inhibitor from Tetra Therapeutics
Today, Tetra Therapeutics announces the first unequivocally positive phase 2 clinical trial in Fragile X syndrome, press release below. The results do not depend on carving out a subset of patients or post hoc analysis.
Read moreScientists Find a New Way to Reverse Symptoms of Fragile X
FRAXA Investigator and MIT Professor Mark Bear and his colleagues have identified a valuable new target for Fragile X therapeutics: GSK3 alpha. Several FRAXA research teams previously identified GSK3 beta as a treatment target for Fragile X. The catch is that, so far, GSK3 beta inhibitors have proven too toxic for regular use. Dr. Bear’s new discovery opens up the possibility of developing more selective compounds with less toxicity and fewer side effects. Interestingly, lithium inhibits both GSK3 versions – alpha and beta.

Tetra Discovery Partners has signed a multi-part deal that could bring it up to $160 million, plus royalties, from Shionogi & Co, Ltd, a Japanese major research-driven pharmaceutical company. Tetra currently is conducting an investigational Phase 2 study of BPN14770 in adults with Fragile X Syndrome, an indication for which BPN14770 has received Orphan Drug Designation from the US Food and Drug Administration. This clinical trial was made possible by early work with the FRAXA-DVI and over $200,000 from FRAXA.

Read moreNIH Investigator Carolyn Beebe Smith, PhD, Looks to Improve Sleep in Fragile X Syndrome
Our sons with Fragile X Syndrome typically go to bed early and rise early. Sometimes they jump on us while we are sleeping at 3 a.m., excited to start their day. For heaven’s sake, why? The answer may come from Carolyn Beebe Smith, PhD, senior investigator, Section on Neuroadaptation and Protein Metabolism, National Institute of Mental Health, National Institutes of Health, Bethesda, Maryland. She is studying why children, in particularly boys, with FXS have problems sleeping.
Read moreNew compound from Anavex Improves Learning and Behavior in Fragile X Mice
A potential new treatment for Fragile X syndrome is showing promise. While still early in development, the investigational drug was able to improve intellectual, learning and hyperactivity measures in a mouse model of Fragile X syndrome. Anavex 2-73 is a sigma-1 receptor agonist being developed for autism spectrum disorders, including Rett syndrome and Fragile X syndrome, and for Alzheimer’s disease. Anavex Life Sciences presented the data at the Gordon Research Conference for Fragile X and Autism-Related Disorders, held June 5-10, 2016 in Mount Snow, VT. The study was sponsored by FRAXA, via the FRAXA Drug Validation Initiative, and performed by Fraunhofer Chile Research, in Santiago, Chile.
