Finding a Cure for Fragile X
Metformin is commonly prescribed to control high blood sugar in type 2 diabetes. With a $50,000 grant from FRAXA Research Foundation, Dr. Artuela Çaku and Dr. Francois LePage are conducting an open-label clinical trial of metformin for children and adults with Fragile X syndrome, at the University of Sherbrooke in Canada.

FRAXA Research Foundation has awarded a $90,000 research fellowship to Dr. Tue Banke. With this award, Dr. Banke is investigating how glutamate receptors at neuronal synapses – essential building blocks of learning and memory – are impacted in Fragile X syndrome. Dr. Banke recently left Aarhus University in Denmark to continue his research first as a visiting scholar and now as an assistant professor at the University of Washington.

FRAXA Research Foundation and the Fragile X Research Foundation of Canada have awarded a grant of $100,000 over two years to Dr. Raymond Turner at the University of Calgary in Alberta, Canada. Dr. Turner and postdoctoral fellow Xiaoqin Zhan, PhD are attempting to reactivate a segment of FMRP to reverse symptoms of Fragile X in a mouse model of the disease to reduce abnormal behaviors.

FRAXA Research Foundation has awarded a $90,000 grant to Principal Investigator Dr. Sean McBride and Postdoctoral Fellow Dr. Karen Joyce, at Rowan University, to screen all 2,320 FDA-approved drugs on both mouse and fly models of Fragile X syndrome. Those drugs which show promise will be tested in more detail for potential to treat Fragile X in humans.

Caffeine is the most popular smart drug in the world. With a $90,000 grant from FRAXA Research Foundation, Alberto Martire, PhD and Antonella Borreca, PhD in Rome, Italy are investigating adenosine receptors antagonists to treat Fragile X syndrome. Compounds which are able to block adenosine receptors are commonly found in tea, chocolate, and coffee.

With this $20,000 award from FRAXA Research Foundation, Dr. Vanderklish and collaborators at Scripps Research Institute, the University of Chile, and the FLENI Institute in Argentina are analyzing patterns in gene expression in blood cells of patients with Fragile X syndrome. They are using “transcriptomics” which can produce a time-sensitive signature of an individual person. This is the first time that all these different levels of study – from transcriptomics to behavior – have been done for individual patients with Fragile X.

FRAXA Research Foundation funded a grant of $90,000 over 2016-2018, for a postdoctoral fellowship for Thomas Maurin, PhD, working under the mentorship of Dr. Barbara Bardoni at INSERM in France. The team works on the biochemistry of the Fragile X protein. They have found that PDE inhibitors (a class of drugs) show promise as treatments for Fragile X syndrome. In related research, FRAXA is currently funding a clinical trial of PDE4D inhibitors.

This 2017-2018 grant of $90,000 is funded jointly by FRAXA and the Fragile X Research Foundation of Canada for the first year. A previous FRAXA grant to the Sonenberg lab has led to great interest in the available drug, metformin, as a potential treatment for Fragile X syndrome. FRAXA is currently organizing clinical trials of metformin.

With a $90,000 grant from FRAXA Research Foundation over 2018-2019, Dr. Patrick McCamphill, postdoctoral fellow in Dr. Mark Bear’s lab at Massachusetts Institute of Technology (MIT), is investigating drug tolerance to mGluR5 antagonists, arbaclofen, and other potential Fragile X treatments. He is also exploring ways to overcome it.

FRAXA Research Foundation initially partnered with Healx in 2016 to identify existing drugs with potential to treat Fragile X syndrome, using machine learning algorithms and computational biology. The study produced results, and now FRAXA and Healx have launched a new round of studies to evaluate combinations of compounds, including both drugs and natural products.
