Research Points to Drugs which Inhibit PDE to Treat Fragile X

Research Points to Drugs which Inhibit PDE to Treat Fragile X

FRAXA Research Foundation funded a grant of $90,000 over 2016-2018, for a postdoctoral fellowship for Thomas Maurin, PhD, working under the mentorship of Dr. Barbara Bardoni at INSERM in France. The team works on the biochemistry of the Fragile X protein. They have found that PDE inhibitors (a class of drugs) show promise as treatments for Fragile X syndrome. In related research, FRAXA is currently funding a clinical trial of PDE4D inhibitors.

Tetra Discovery Partners Initiates Phase 2 Trial of BPN14770 in Fragile X Syndrome

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.

Fragile X Clinical Trial of New PDE4D Inhibitor from Tetra funded by FRAXA

Fragile X Clinical Trial of New PDE4D Inhibitor from Tetra funded by FRAXA

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.

Targeting AMP-Activated Protein Kinase Pathway in Fragile X Syndrome

Targeting AMP-Activated Protein Kinase Pathway in Fragile X Syndrome

With a $100,000 grant from the FRAXA Research Foundation in 2015, Dr. Peter Vanderklish explored a novel strategy to treat Fragile X syndrome: AMPK activators. The good news is that there are FDA approved (for example, metformin) and naturally occurring AMPK activators (such as resveratrol, found in red wine).

FRAXA Research Outlook 2012 – Treatment Trials and the Next Wave of New Drugs

Treatment Trials As you probably know, three pharmaceutical companies are conducting clinical trials in Fragile X. Two Swiss giants, Novartis and Roche, are racing to get their lead mGluR5 antagonists to market, and U.S. startup Seaside Therapeutics is pursuing a compound which targets the brain receptor, GABAB. Novartis has large-scale Phase IIb/III trials of the drug AFQ056 well underway. Sites worldwide are enrolling adolescents and adults, with 35 more adults needed and recruitment of adolescents planned through Fall 2012. At this point, some participants have already completed the placebo-controlled trial and are now taking AFQ056, with the option of continuing it until it reaches the market. Novartis is also working toward a trial of AFQ056 for younger children with Fragile X. Roche completed a Phase II trial of its mGluR5 antagonist (currently with the catchy name of RO4917523) last year and is about to commence a larger Phase II trialRead more
