Healx Raises $56M to use AI to Find Treatments for Fragile X & Other Rare Diseases

Healx has secured $56M in new financing to build a clinical-stage portfolio for rare diseases, including treatments for Fragile X syndrome, and to launch a global Rare Treatment Accelerator program. Where the traditional drug discovery model takes more than a decade and can run into the billions of dollars, Healx’s AI-driven approach makes the process faster, more efficient and cost-effective.

Repurposing Available Drugs to Treat Fragile X Syndrome – FRAXA Initiatives

FRAXA Research Foundation was founded in 1994 to fund biomedical research aimed at finding a cure for Fragile X syndrome and, ultimately, autism. We prioritize translational research with the potential to lead to improved treatments for Fragile X in the near term. Our early efforts involved supporting a great deal of basic neuroscience to understand the cause of Fragile X. By 1996, these efforts had already begun to yield results useful for drug repurposing. To date, FRAXA has funded well over $25 million in research, with over $3 million of that for repurposing existing drugs for Fragile X.

NIH Investigator Carolyn Beebe Smith, PhD, Looks to Improve Sleep in Fragile X Syndrome

Our sons with Fragile X Syndrome typically go to bed early and rise early. Sometimes they jump on us while we are sleeping at 3 a.m., excited to start their day. For heaven’s sake, why? The answer may come from Carolyn Beebe Smith, PhD, senior investigator, Section on Neuroadaptation and Protein Metabolism, National Institute of Mental Health, National Institutes of Health, Bethesda, Maryland. She is studying why children, in particularly boys, with FXS have problems sleeping.

Why Did Fragile X Clinical Trials of mGluR Antagonists Fail?

Michael Tranfaglia, MD Clinical Trials • Research Updates August 15, 2014November 19, 2019AFQ056, arbaclofen, baclofen, drug tolerance, lithium, mGluR, mGluR5, minocycline, Novartis

by Michael Tranfaglia, MD. In my opinion, the Fragile X clinical trials of AFQ056 sponsored by Novartis failed because of a dose range that was inadequate for Fragile X, and because of the unexpected development of tolerance.

Social Behavior as an Outcome Measure for Fragile X Clinical Trials

One of the features of the Fragile X mouse model which is relevant to the human Fragile X syndrome (and autism) is social behavior. Several tests show consistent social behavioral abnormalities in the Fragile X mouse model. With a $140,000 grant from FRAXA Research Foundation in 2012-2013, Dr. Willemsen at Erasmus University used social behavior tests to measure the effectiveness of several drug strategies.

Genome-wide Epigenetic Markers in Fragile X

With $45,000 in grants from FRAXA Research Foundation over several years, Dr. Miklos Toth of Cornell University studied epigenetics (ie factors other than the gene itself) which can determine symptom severity in Fragile X.

Baclofen: GABA(B) Receptor Supersensitivity and Normalization of Behavioral Abnormalities by Various GABA(B) Agonists Including Baclofen in FMRP Deficient Mice

With $110,000 in grants from FRAXA Research Foundation over several years, Dr. Miklos Toth from Cornell University discovered increased startle response in Fragile X mice and that baclofen can correct this phenotype.
