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.

  • More about this trial

    The purpose of this study is to assess the safety and efficacy of two dose levels of NNZ-2566 when compared to placebo in adolescent and adult males (ages 14-40) who have been diagnosed with FXS.

    NNZ-2566 has a novel mechanism of action compared with other drugs that have been tested for Fragile X syndrome. It is a modified version of a biologically active part of Insulin-like Growth Factor (IGF-1). IGF-1 is a protein that helps cells grow and respond to stress or damage. In the brain, IGF-1 contributes to the growth of brain cells and the connections between them (synapses).

    The biologically active part of IGF-1 is called glypromate or GPE and supports the function of brain cells in a different way than IGF-1.  GPE occurs naturally in the brain. NNZ-2566 is a version of GPE modified to make it available to take as an oral medication. NNZ-2566 may help improve brain function by enhancing functions normally performed by GPE and by increasing IGF-1 levels in the brain. NNZ-2566 has been shown in animal models of Fragile X to improve performance in tests of behavior and cognition.

    FDA has granted two special designations for Neuren’s development of NNZ-2566 in Fragile X: Fast Track Designation and Orphan Drug Designation.

    This trial will include 60 participants between the ages of 14-40. Taking part in this study involves 8 visits to the doctor’s office over 10 weeks. The study medication and all study-related evaluations will be provided at no cost. Some support for travel is available.
