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

Synaptogenix 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.

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

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.

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

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

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”.

NIH 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.

Neuren’s Tofinetide Successful in Phase 2 Clinical Trial in Fragile X

Neuren’s Tofinetide Successful in Phase 2 Clinical Trial in Fragile X

We are pleased to share great news adapted from Neuren’s press release: Neuren’s phase 2 trial has successfully established proof of concept and provides a strong rationale for Neuren to move forward with developing trofinetide for Fragile X syndrome. In this initial small trial with a relatively short treatment period, trofinetide was very well tolerated, with the high dose (70 mg/kg twice daily) demonstrating a consistent pattern of clinical improvement, observed in both clinician and caregiver assessments.
