Allos Pharma Revives Arbaclofen After 7 Years: New Hope for Fragile X Syndrome
Allos Pharma Inc launches a new development program for arbaclofen to treat Fragile X syndrome. This experimental drug missed its primary endpoint in clinical trials.
Auditory System Dysfunction and Drug Tolerance in the Fragile X Mouse
A $90K FRAXA grant will help uncover why Fragile X causes sound hypersensitivity and test ways to correct brain circuit dysfunction linked to auditory overload.
Scientists Find a New Way to Reverse Symptoms of Fragile X
MIT Professor Mark Bear and colleagues have identified a new target for Fragile X therapeutics: GSK3 alpha. Several FRAXA research teams previously identified GSK3 beta as a treatment target.
Potassium Channel Modulators to Treat Fragile X
FRAXA-backed Yale discoveries tied Fragile X to Kv3.1/Slack channel defects—leading to a partnership with Autifony to develop targeted treatments.
NKCC1 Inhibitor Bumetanide Corrects Synaptic and Circuit Hyperexcitability in Fragile X Mouse Model
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.
Understanding and Reversing Hypersensitivity to Sounds in Fragile X Syndrome
This FRAXA grant studied why people with Fragile X are overly sensitive to sound and tested drug strategies to calm the brain’s overactive auditory circuits.
