Aripiprazole (Abilify) in the Treatment of People with Fragile X: An Anecdotal Account
The aim of this article is to discuss the use of Abilify (generic name: aripiprazole) as a treatment for people with Fragile X syndrome (FXS). As an “off-label” prescription, Abilify targets behaviors such as irritability, aggression, self-injury and severe tantrums.
Brain Organoids and Therapeutic Development for Fragile X and Other Rare Diseases
This is the first in a series of webinars focused on current topics in Fragile X research. In this webinar we hear from Alysson R. Muotri, PhD, Professor at University of California San Diego Stem Cell Programand Fabio C. Tucci, PhD, Chief Operating Officer and co-founder at Epigen Biosciences, Inc.
Companies Move to Advance Potential Cognitive Treatment for Fragile X
Tetra Therapeutics and Shionogi announced plans to expand their partnership supporting BPN14770, a treatment candidate for disorders marked by cognitive and memory deficits, including Fragile X syndrome and Alzheimer’s disease. The agreement builds on an earlier collaboration between the two companies, and aims to further accelerate BPN14770’s development and potential marketing. It is currently in clinical testing in both Fragile X and Alzheimer’s patients.
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.
Screening 2,320 FDA-Approved Drugs for Potential Treatment of Fragile X
FRAXA funded a screen of 2,320 FDA-approved compounds in the Fragile X fly model to identify hits that improve memory and social behavior for advanced testing.
Tetra Announces $40M to Advance BPN14770 for FXS and Alzheimer’s Disease
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.
Tetra Discovery Partners Initiates Phase 2 Trial of BPN14770 in Fragile X Syndrome
This 2-Period Crossover Study of BPN14770 is accepting adults males with Fragile X syndrome at Rush University Medical Center in Chicago. Principal Investigator of the study is Elizabeth Berry-Kravis, MD, PhD.
A selective inhibitor of the phosphodiesterase type-4D (PDE4D), BPN14770 has shown the ability to improve the quality of connections between neurons and to improve multiple behavioral outcomes in the Fragile X mouse model.
Takeaways from Fragile X Advocacy Day
At my first Fragile X Advocacy Day, I met with Congress and families, advocating together for research and hope.
Repurposing Study II: Evaluating Combinations of Drugs to Treat Fragile X
FRAXA partnered with Healx to use AI to find approved drugs and drug combos that could treat Fragile X. Top candidates are now being tested in Fragile X models.
Newly Discovered Regulatory Pathways in Fragile X
Studies at Yale University and elsewhere are showing that FMRP plays a significant role in the regulation of potassium channels. Looking forward, potassium channel opener drugs could rescue some symptoms of Fragile X in humans.
In Their Own Words: Reports From the International Fragile X Workshop
The 18th International Fragile X Workshop in Quebec was a great success, featuring more Fragile X research than ever before!
Development of a High-Content Synapse Assay to Screen Therapeutics for Fragile X Syndrome
This work established a high-content synaptic imaging platform for Fragile X cells to test many candidate drugs for their ability to repair synapse structure and function.
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
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.
Targeting AMP-Activated Protein Kinase Pathway in Fragile X Syndrome
With this grant from FRAXA, Dr. Peter Vanderklish explored AMPK activators to treat Fragile X. Both metformin and resveratrol, found in red wine, are AMPK activators.
Fruit Flies to Model and Test Fragile X Treatments
Boosting cAMP signaling restores memory and fixes brain-signaling defects in Fragile X models, suggesting diabetes drugs like metformin may help.
Effects of Metformin in Fmr1 Knockout Mouse Model of Fragile X Syndrome
Metformin, a safe diabetes drug, activates AMPK to rebalance protein synthesis. FRAXA-funded work investigated its potential to treat Fragile X.
Clinical Trials FAQ ← Frequently Asked Questions
Question: How Do Families Decide Which Trial is Best for Them? Answer: Each of the trials has different requirements for joining, so many – if not most – people will only be eligible for one trial after screening. The best way to approach this is to call the clinic contact closest to your area and discuss this with him/her. Age, weight, current medications, behavior, and IQ are all factors.
Serotonergic Rescue of Synaptic Plasticity in FMR1 Knockout Mice
Dr. Zhu examined how serotonin-targeting drugs such as Buspar and Abilify influence synaptic plasticity, including LTP and LTD.
