Aripiprazole (Abilify) in the Treatment of People with Fragile X: An Anecdotal Account

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.

Scientists Find a New Way to Reverse Symptoms of Fragile X

Scientists 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.

Companies Move to Advance Potential Cognitive Treatment for Fragile X

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.

Ketogenic Diet Eases Symptoms in Fragile X Male Mice

Ketogenic Diet Eases Symptoms in Fragile X Male Mice

The Westmark laboratory continues to study sleep and rest-activity cycles in Fragile X mice as a potential outcome measure that correlates between preclinical and clinical research. The analysis of sleep EEG in the mice has proven more labor intensive than they anticipated, but the team is collaborating with Dr. Rama Maganti’s laboratory at UW-Madison on the development of computer scrips to speed up the analysis.

Considering Available Drugs for Fragile X: My Favorite Combination (So Far)

Considering Available Drugs for Fragile X: My Favorite Combination (So Far)

Which of the available drugs are best for fragile X? We tend to think of drugs according to their primary activity in the body, but very few drugs are totally selective and specific. There are differences between drugs in any given class, and these differences may be critical. Most drugs have “off-target” effects which are usually considered side effects, and it is these side effects which can have key advantages, in some cases.

fNIRS to Measure Treatment Response in Young Children with Fragile X

fNIRS to Measure Treatment Response in Young Children with Fragile X

FRAXA Research Foundation has awarded a $90,000 research grant to Dr. Craig Erickson and Dr. Elizabeth Smith at Cincinnati Children’s Hospital to test functional near-infrared spectroscopy (fNIRS), in children who have Fragile X syndrome. fNIRS is safe, non-invasive, and easily-tolerated. It uses light sources and sensors on the scalp to build a heat map of the brain in action.

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.

National Institutes of Health Releases Fragile X Strategic Plan

National Institutes of Health Releases Fragile X Strategic Plan

FRAXA Program Coordinator, Elle Skala, and long time FRAXA supporter and previous Board Member, Mary Beth Busby, traveled to the National Institutes of Health earlier this week. The timing of this meeting was perfect because the National Institutes of Health (NIH) just released their long-anticipated Strategic Plan for Fragile X Syndrome, FXTAS, and FXPOI. It will guide federal Fragile X research funding for at least the next five years and open the door for continued funding of the Fragile X Research Centers of Excellence.

Fragile X Clinical Trial of New PDE4D Inhibitor from Tetra

Fragile X Clinical Trial of New PDE4D Inhibitor from Tetra

FRAXA Research Foundation has funded a clinical trial of an investigational new drug, led by Dr. Elizabeth Berry-Kravis at the Rush Fragile X Clinic in Chicago. This trial will treat 30 adult males with Fragile X syndrome with a PDE4D allosteric inhibitor from Tetra Discovery Partners using in a crossover design, so that everyone gets active drug for part of the time and placebo for part of the time.

Coffee, Tea, and Chocolate: Adenosine Receptors in Fragile X

Coffee, Tea, and Chocolate: Adenosine Receptors in Fragile X

Caffeine is the most popular smart drug in the world. With a $90,000 grant from FRAXA Research Foundation, Alberto Martire, PhD and Antonella Borreca, PhD in Rome, Italy are investigating adenosine receptors antagonists to treat Fragile X syndrome. Compounds which are able to block adenosine receptors are commonly found in tea, chocolate, and coffee.
