Read morePositive Results Reported in Phase II Fragile X Clinical Trial of PDE4D Inhibitor from Tetra Therapeutics
Today, Tetra Therapeutics announces the first unequivocally positive phase 2 clinical trial in Fragile X syndrome, press release below. The results do not depend on carving out a subset of patients or post hoc analysisAn analysis after seeing the test results, and it can lead to bias, because researchers are able to test the data in any way that produces a favorable result. This trial is the result of many years of rational drug discovery funded by FRAXA. The therapeutic target, PDE4, has been identified by multiple researchers including FRAXA Investigators Tom Jongens, Sean McBride, Elizabeth Berry-Kravis, Nobel laureate and FRAXA scientific advisor Eric Kandel. PDE4 is one of the best validated Fragile X treatment targets and we believe this is a genuinely disease-modifying therapy. (Because PDE4 inhibitors are famous for causing nausea; Tetra's compound targets a subtype of PDE4D, thus largely avoiding GI upset.) Many researchers have expressed doubtsRead more
