Fragile X Clinical Trial of New PDE4D Inhibitor from Tetra

With a $200,043 grant from FRAXA Research Foundation, Dr. Elizabeth Berry-Kravis completed a successful Phase 2 clinical trial of a PDE4 inhibitor for adult men with Fragile X syndrome. This trial treated 30 males, 18-45 years of age with a new PDE4D allosteric inhibitor from Tetra Discovery Partners using a crossover design, so that everyone got active drug for part of the time and placebo for part of the time.

Repurposing FDA-Approved Drugs to Treat Major Depressive Disorder in Fragile X Syndrome

Did you know that depression is more common in those with autism and/or Fragile X? Even more disturbing is the discovery that current treatments for depression do not work in Fragile X mice. With this grant, the team will work to develop a rapid screening tool to identify FDA-approved drugs which can treat depression in people with Fragile X syndrome.

Synaptogenix Announced Intention to Launch a Fragile X Clinical Trial with Bryostatin

Fragile X Clinical Trials

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.

Results Reported: Using EEG Responses to Sound for Fragile X Drug Discovery

Jonathan Lovelace, a FRAXA funded Postdoc at UC Riverside, has made some exciting EEG findings over the past few years studying auditory hypersensitivity in mice and therapeutic drug treatments. A big obstacle in FXS research has been establishing reliable, unbiased, and translation relevant biomarkers that can be used to determine the effectiveness of therapies. One of the most important discoveries they have made is the striking similarity in EEG biomarkers between mice and humans.

Takeaways from Fragile X Advocacy Day

In the first week of March I attended my first Fragile X Advocacy Day to meet with many of the Massachusetts delegation to Congress. While this was my first time advocating for Fragile X research, I’ve been a longtime lung cancer research advocate and have met with many of the same representatives in the past. It was a pleasure to meet with many of the families as my participation in Advocacy Day was in the spirit of “we are all in this together”.

Repurposing Study II: Evaluating Combinations of Drugs to Treat Fragile X

Healx team 2018

FRAXA Research Foundation initially partnered with Healx in 2016 to identify existing drugs with potential to treat Fragile X syndrome, using machine learning algorithms and computational biology.  The study produced results, and now FRAXA and Healx have launched a new round of studies to evaluate combinations of compounds, including both drugs and natural products.
