Studying human Fragile X neurons from stem cells revealed key gene changes not seen in mice—showing why some treatments failed and guiding better future therapies.
Fragile X brain cells have fewer, smaller mitochondria. This team tested mitochondria-boosting drugs that improved symptoms in mice to see if they can help humans.
FRAXA funded UCLA research on a Kv3.1-targeting drug to ease sensory issues in Fragile X. This work built on Yale-led work now also being pursued by Autifony Therapeutics.
With FRAXA funding, researchers tested AAV gene therapy to restore FMRP in Fragile X mice, measuring safety, effectiveness, and brain activity to inform future trials.
Many forms of FMRP exist in the brain. This project aims to pinpoint which versions of the protein are most critical to restore for effective Fragile X treatments.
A FRAXA-funded team found that a shortened FMRP protein, delivered with a Tat “carrier,” restores brain signaling and improves behavior in Fragile X mice.
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.
FRAXA-funded Yale research showed disrupted Kv3.1 and Slack potassium channels impair neuronal timing in Fragile X. Published findings support Kv3.1 as a treatment target.
FRAXA’s $90K grant enabled Dr. Zukin to link impaired autophagy to Fragile X. Boosting autophagy restored synaptic proteins and reversed cognitive deficits in mice.
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.
Meet #FriendofFRAXA Charlie! If you would like to nominate someone as a #FriendofFRAXA, we welcome all who have been touched by Fragile X, including friends, grandparents, siblings, professionals and companions alike to become a #FriendofFRAXA with the goal of putting a face to Fragile X for those who may not know someone directly.
Could “caffeine-like” drugs help Fragile X? FRAXA funded research to test adenosine blockers, which may boost thinking and improve symptoms in Fragile X mice.
Meet #FriendofFRAXA Emily! If you would like to nominate someone as a #FriendofFRAXA, we welcome all who have been touched by Fragile X, including friends, grandparents, siblings, professionals and companions alike to become a #FriendofFRAXA with the goal of putting a face to Fragile X for those who may not know someone directly.
Dr. Anis Contractor and Dr. Qionger He investigated the potential of the available drug bumetanide to correct altered GABA signalling in a mouse model of Fragile X syndrome.
FRAXA funded a study using blood-based transcriptomics to find reliable Fragile X biomarkers. This unique approach links molecular data to behavior for future trials.
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.
FRAXA-funded research is revealing how insulin signaling is altered in Fragile X and whether lowering it, including with metformin, could ease symptoms.
