Altered Sleep in Fragile X Syndrome: Basis for a Potential Therapeutic Target
With this FRAXA grant, Dr. Carolyn B. Smith and Dr. Rache Sare at the National Institute of Mental Health investigated the basis of sleep problems in Fragile X syndrome.
FX-Learn Clinical Trial for Children with Fragile X
Thirteen centers across the US enrolled children with Fragile X in a large-scale clinical trial of Novartis AFQ056. Dr. Elizabeth Berry-Kravis and colleagues aim to show that this targeted treatment — an mGluR5 blocker for Fragile X which failed in previous adult human trials — can be better evaluated by studying effects on learning in young children.
Clinical Trial of Metformin for Fragile X Syndrome
FRAXA-funded open-label trial found that metformin led to increased GABA-mediated cortical inhibition, suggesting metformin modulates core Fragile X pathways.
Memorial Tribute to Dr. Stephen T. Warren
Dr. Stephen T. Warren, who discovered the Fragile X gene (FRAXA) in 1991, passed away June 6, 2021. Donations in his honor support FRAXA Research.
Pivotal Phase 3 Trial of Zygel in Severe Fragile X Possible This Year
Zynerba Pharmaceuticals reported receiving advice from the U.S. Food and Drug Administration (FDA) on the design of an upcoming Phase 3 clinical trial meant to confirm previous trial findings supporting Zygel as a cannabidiol treatment in a specific subset of Fragile X syndrome patients. The new trial, called RECONNECT, is expected to launch before October, and will mainly enroll children and adolescents with a complete (100%) methylation of FMR1, the gene mutated in Fragile X.
Cellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome
The team studied how inhibitory brain circuits malfunction in Fragile X and tested ways to restore balance by targeting mGluR and endocannabinoid signaling.
FRAXA Supports Increased Funding for NICHD
FRAXA has joined the Friends of NICHD coalition, urging increased government funding for research into Fragile X and related conditions.
