To those of you who have family members with Fragile X, thank you for being interested in clinical trials! This is a challenging phase for all of us, and as exciting as it is, we know many of you have questions about what it means to be in a clinical trial.
Each study is supervised by a doctor that specializes in Fragile X. These trials are free, you do not have to tell your insurance company, and you can leave any time you want. Travel costs are usually covered.
The FDA requires two successful large-scale clinical trials before it will consider approving a new treatment. If studies are successful and the FDA approves new drugs, others with Fragile X can also have access to these medicines.

“Consistent with the mechanism of action and preclinical studies, anxious FXS patients treated with ganaxolone showed clinically relevant reductions in anxiety across several scales and subscales sensitive to measuring changes in anxious behavior. These results are encouraging and suggest that ganaxolone may improve anxiety in children with FXS, which could potentially allow them, as well as their families, to experience a more stabilized lifestyle.” – Frank Kooy, PhD.
