The FRAXA Drug Validation Initiative (FRAXA-DVI) provides speedy, cost-effective, objective preclinical testing to validate investigational and repurposed compounds for Fragile X.
Mirum’s MRM-3379 Phase 2 trial builds on FRAXA-funded PDE4D research and is now enrolling males ages 13–45 with Fragile X syndrome. View eligibility and study sites.
Shionogi shares an update on its zatolmilast Fragile X clinical trials, outlining progress in U.S. studies and next steps in data analysis and evaluation.
Fragile X Research Q&A with Dr. Berry-Kravis on RECONNECT results, placebo effects, outcome measures, methylation, and research directions for families.
Learn more about Shionogi’s EXPERIENCE clinical trials for adults and adolescents with Fragile X syndrome, FRAXA’s role, and the open-label extension of these trials.
NPR spotlights zatolmilast, a promising investigational drug to treat Fragile X syndrome. Families report life-changing improvements in learning and independence.
A $200K FRAXA grant enabled a successful Phase 2 trial of a PDE4D inhibitor for adult men with Fragile X, showing strong cognitive gains without side effects or tolerance.
Dr. Mark Gurney of Tetra Therapeutics, discusses how one of the earliest clues to the biology of Fragile X led to the most successful Fragile X clinical trial to date: a phase 2 trial of a PDE4D inhibitor.
Today, Tetra Therapeutics published the full results of its PDE4D trial. The data from this phase 2 clinical trial suggests the PDE4D drug can improve intellectual disability in Fragile X syndrome.
In this Simons Foundation lecture, Elizabeth Berry-Kravis traces 30 years of Fragile X research, from identifying its cause through a series of disappointing clinical trials.
Tetra Therapeutics announces the first unequivocally positive phase 2 clinical trial in Fragile X syndrome. The results do not depend on carving out a subset of patients or post hoc analysis.
Tetra Therapeutics and Shionogi announced plans to expand their partnership supporting BPN14770, a treatment candidate for disorders marked by cognitive and memory deficits.
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.
FRAXA-funded work identified PDE enzymes as key targets in Fragile X, showing that PDE inhibitors can fix signaling and boost synaptic function. PDE4D trials are underway.
University of California researchers Khaleel Razak, PhD, and Jonathan W. Lovelace, PhD, explored drug combinations to limit hypersensitivity to sounds in Fragile X mice.
A clinical trial of minocycline in children with Fragile X found significantly better global improvement vs. placebo, supporting its safety and potential.
With a $220,000 FRAXA grant, Dr. Iryna Ethell’s team at UC Riverside uncovered MMP-9’s role in Fragile X—leading to a major treatment strategy using minocycline.
