On September 14, 2021, we held an NFXF Webinar with three of our industry partners working on treatments for Fragile X syndrome. Each shared the most up-to-date information on their research project(s) in a way that is understood by those who aren’t steeped in drug research day in and day out.  A short Q&A followed each presentation.

Presenters include representatives from:

Below we have provided on-demand versions of each presentation.

Allos Pharma

Randy Carpenter, MD

Allos is has obtained the license for arbaclofen (STX209), a drug that reached clinical trial status for Fragile X syndrome with Seaside Pharmaceuticals.

Families and professionals expressed their disappointment in the STX209 program ending. There was hope that the data would be made available for future research and possibly to even help with future trials to study arbaclofen in FXS for a drug approval. Until now, this has not been an option. Allos plans to meet with FDA about the future of arbaclofen in FXS.

We have been able to work with the organization storing the data to move forward with obtaining your data, but we need your help! If your child participated in the trial, please consider giving your permission to provide the data for future research. It just might be help discover a new treat. The process is easy. Learn more on our STX209 Reconsent page.

Tetra Therapeutics

Chad Coberly

Tetra is developing BPN14770/zatomilast for treating cognition and daily function in Fragile X syndrome.

Tetra previously completed a trial of BPN14770 in adult men with FXS. You can read our summary of a paper published on the research this past summer.

Tetra plans to move forward with BPN14770 in FXS, likely opening future trials with broader age ranges in late 2021. Stay tuned for more details.

Zynerba Pharmaceuticals

Joseph Palumbo, MD

Zynerba previously completed a trial of ZYN002, a clear cannabidiol gel applied to the skin, in children and adolescents with FXS.

Zynerba is moving forward with ZYN002 in FXS and is actively recruiting 3-17 year olds with FXS.  The details of the trial will be on our MyFXResearch portal shortly.

Developing new treatments for Fragile X is a team effort.

We will not be able to have more effective treatments or a drug on the market to target Fragile X without your help.  Consider participating in research opportunities – which range from surveys to more involved clinical trials. Researchers work with us to connect participants to them for their research and trials because, without you, research would not happen. Please take a moment to review currently available opportunities at our MyFXResearch page.

We are dedicated to advancing treatment research. We believe in scientifically sound research that has the community at the heart of the work. After all, you are the ones who will be using the treatments! 

We advance treatment research by doing the things we do best: 

While there are drugs and non-drug interventions that help address the symptoms of FXS, we do not have a drug for FXS. And we will likely need more than one treatment to help every person living with Fragile X. This process, the work of our industry and academic research partners, and the FDA’s oversight ensure that when there is a drug for FXS it will be safe and effective. Together, We’re Stronger!
