The FRAXA Drug Validation Initiative (FRAXA-DVI) provides speedy, cost-effective, objective preclinical testing of potential Fragile X treatments. FRAXA-DVI uses in-vitro systems, behavior batteries, and gene expression and peripheral biomarker platforms to validate investigational new drugs and repurposed available compounds in Fragile X syndrome (FXS).

FRAXA Research Foundation has funded this resource every year since 2011.

Featured Treatment Development Programs and Clinical Trials Launched by FRAXA-DVI

This resource is having tremendous impact on the Fragile X field. FRAXA-DVI has tested over 100 compounds, generating new leads and enabling many development programs currently underway worldwide. Some programs have already launched clinical trials; others are in earlier stages along the drug development pipeline. Here are a few examples:



P70 S6 KINASE INHIBITOR – Epigen Biosciences
Preclinical studies are in progress.

This Greece-based company partners with FRAXA and FRAXA-DVI to identify drug repurposing candidates against Fragile X Syndrome.

In partnership with FRAXA-DVI, this company is developing therapeutics aimed at neuron regeneration.


Phase II Clinical Trials

TROFINETIDE – Neuren Pharmaceuticals
Phase II Clinical Trial for Fragile X is complete; Trials in other rare diseases are underway.

Sulindac – Healx
Phase II Clinical Trial in Fragile X will launch in summer 2021.


Phase III Clinical Trials

BPN14770 – Tetra Therapeutics
Phase II Clinical Trial in Fragile X was successful, Phase III trial in Fragile X are now being planned
