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.

Read moreSynaptogenix Announced Intention to Launch a Fragile X Clinical Trial with Bryostatin
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.

With this grant, the team will identify the pathways responsible for this excessive activation and attempt to reverse the excess. If they can correct this using drugs, they will be able to identify a new potential treatment for Fragile X syndrome solving one more piece of the Fragile X brain puzzle.
Read moreScreening Combinatorial Pharmacological Therapies for Fragile X Syndrome
FRAXA Research Foundation has awarded a $90,000 research grant to Stanford University principal investigators Dr. Philippe Jacques Mourrain and Dr. Gordon Wang, along with postdoctoral fellow, Dr. Rochelle Coulson. They are evaluating additive effects of combinatorial drug treatments to correct a broad spectrum of deficits observed in Fragile X syndrome.
Read moreBryostatin-1 in Long-term Use Seen to Arrest Fragile X Symptoms in Mouse Model
Long-term, but not short-term, treatment with bryostatin-1 — Neurotrope’s lead investigational therapy — arrested such behavioral and cognitive symptoms as hyperactivity, difficulties with daily life activities, and learning and memory deficits in a mouse model of Fragile X syndrome.
Read morePositive Results Reported in Phase II Fragile X Clinical Trial of PDE4D Inhibitor Zatolmilast 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.
