The FRAXA Drug Validation Initiative (FRAXA-DVI) provides speedy, cost-effective, objective preclinical testing to validate investigational and repurposed compounds for Fragile X.
Kaerus Bioscience’s BK channel openers for Fragile X syndrome are advancing through Phase 1 trials, offering hope for new treatments with FRAXA’s continued support.
A promising new BK channel opener, SPG601 from Spinogenix, is entering clinical trials for Fragile X syndrome. Learn about its potential to restore synaptic function and address core symptoms.
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.
Studies at Yale University and elsewhere are showing that FMRP plays a significant role in the regulation of potassium channels. Looking forward, potassium channel opener drugs could rescue some symptoms of Fragile X in humans.
With $366,100 in FRAXA funding, researchers tested BK channel–opening drugs to fix sensory abnormalities in Fragile X mice; early results showed broad behavioral rescue.
A number of people have asked us about FRAXADev, a new project starting in France; this is a nonprofit initiative which seeks to develop a new kind of drug for Fragile X. The drugs they are interested in testing in Fragile X clinical trials were developed by Bristol-Myers Squibb many years ago, and are now off patent. This class of drugs opens a potassium channel in the membrane of neurons, which helps to decrease neuronal excitability.
In the wake of negative results from several high-profile clinical trials in Fragile X, we find ourselves questioning many of our previous assumptions about the nature of this disorder. After all, understanding the basic pathology of disease is critical to development of new treatments — this is true across the board, in all branches of medicine.
Study pinpointed presynaptic calcium dysfunction as the driver of STP defects in Fragile X, and BK channel activation restored normal synaptic signaling.
At the start, it’s always hard to know what methods will work best for something as complex as the development of disease-modifying treatments for Fragile X. But, we’ve always tried to let the science lead us down the right path. At this point, the results are unequivocal, and they have shaped how we are looking for the Next Great Thing in Fragile X treatments.
Ion channel defects (“channelopathies”) in Fragile X disrupt neuron firing and network balance. This study maps these channel changes to guide targeted treatments.
With $282,000 in funding from FRAXA Research Foundation, Dr. Leonard Kaczmarek and colleagues explored association of Slack channels with the Fragile X protein (FMRP).
