In November 2020, a phase II clinical trial reported extremely successful results. This clinical trial of a PDE4D inhibitor from Tetra Pharmaceuticals was conducted by Dr. Elizabeth Berry-Kravis at Rush University Medical Center and funded by FRAXA Research Foundation. In this Simons Foundation lecture, Elizabeth Berry-Kravis traces 30 years of Fragile X research, from identifying its cause, through finding dozens of treatment targets, through a series of disappointing clinical trials.

FRAXA Research Foundation has funded a clinical trial of an investigational new drug, led by Dr. Elizabeth Berry-Kravis at the Rush Fragile X Clinic in Chicago. This trial will treat 30 adult males with Fragile X syndrome with a PDE4D allosteric inhibitor from Tetra Discovery Partners using in a crossover design, so that everyone gets active drug for part of the time and placebo for part of the time.
