Tetra’s Fragile X Clinical Trial – The Most Successful So Far

September 7, 2021

Dr. Mark Gurney, CEO of Tetra Therapeutics, discusses how one of the earliest clues to the biology of Fragile X led to the most successful Fragile X clinical trial to date. FRAXA and Tetra began working together after a key FRAXA-funded study caught the attention of Dr. Gurney. Through the FRAXA Drug Validation Initiative, Dr. Patricia Cogram was able to conduct preclinical validation experiments with Tetra’s lead compound in record time, paving the way for clinical trials.

Clinical Trials and Cyclic AMP in Fragile X Syndrome: A Life Journey

March 10, 2021

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.
