Conducting Fragile X clinical trials of combination treatments can be a daunting task, since the number of possible combinations increases exponentially with the number of drugs and the various doses of each one. So Dr. Tranfaglia traveled to Cambridge, England, to meet with the scientists and advisors at Healx to brainstorm the best approaches to this challenge, with the aim of moving ahead as quickly as possible.

Many drugs for fragile X syndrome have failed in large clinical trials, but candidates that target new aspects of the condition may fare better.

With a $66,714 grant from the FRAXA Research Foundation awarded over 2015-2017, Dr. Francois Corbin at the Universite of Sherbrooke will test the safety and synergistic effects of lovastatin and minocycline in patients with Fragile X syndrome.

Mechanisms of Tolerance to Chronic mGluR5 Inhibition

Over the past few years, both Novartis and Roche sponsored large-scale clinical trials of metabotropic glutamate receptor 5 (mGlu5) negative allosteric modulators (NAMs) to treat Fragile X syndrome (FXS). With a $90,000 grant from FRAXA Research Foundation in 2015-2017, Dr. Mark Bear’s team will explore if mGlu5 NAMs dosed chronically causes tolerance, and if so, how it develops and to probe new avenues to prevent or circumvent it.

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. Here are some examples of FRAXA-funded work on repurposing available drugs for Fragile X syndrome: Lithium In the mid-1990s, the Greenough lab at the University of Illinois discovered that FMRP, the protein missing in Fragile X, is rapidly translated in dendrites in response to stimulation of glutamate receptors. FRAXA funded preclinical validation of this discovery in theRead more

Jean-Francois Lepage, PhD, and Francois Corbin, MD, PhD, with MRI machine If all the science world’s a stage, Fragile X researchers are more than merely players. They are center stage. So believes Francois Corbin, MD, PhD, professor, Université de Sherbrooke, Canada, who directs the university’s Fragile X Clinic. Corbin, who has received more than $100,000 in FRAXA support since 2012, is leading a pilot randomized Phase II trial, exploring the tolerability and the synergistic effect of a combined therapy. They will combine minocycline, which is often used to treat acne, and lovastatin, which is used to lower cholesterol. Both drugs target specific alterations in the brain of Fragile X patients that would potentially have a combined powerful effect on their behavior. “To my knowledge, this is the first time we have a clinical trial with two different drugs combined to act on two different targets,” Corbin said. “The combined actionRead more

Lovastatin Discovery in Fragile X Mice Leads FRAXA to Fund Clinical Trials

Available Medication Lovastatin Corrects Excess Protein Synthesis in Fragile X Mice Dr. Emily Osterweil At the opening dinner of the 2011 FRAXA Investigators Meeting in Southbridge, MA, Dr. Emily Osterweil was awarded the FRAXA Pioneer Award for work demonstrating that Lovastatin could treat Fragile X. Dr. Osterweil conducted her experiments in the MIT laboratory of Dr. Mark Bear; she has since established her own laboratory at the University of Edinburgh. The team discovered that lovastatin, a drug widely prescribed for high cholesterol, can correct excess hippocampal protein synthesis in the mouse model of FXS and can prevent epileptogenesis. The work is published in the prestigious neuroscience journal Neuron: Lovastatin Corrects Excess Protein Synthesis and Prevents Epileptogenesis in a Mouse Model of Fragile X Syndrome. One implication of the mGluR theory of Fragile X is that there are exaggerated consequences of activation of signaling pathways which link metabotropic glutamate receptors (mGluRs) to the cellular machinery ofRead more
