4 February 2019 – Neuren Pharmaceuticals advised the Australian Stock Exchange, Melbourne, of a statement released by ACADIA Pharmaceuticals about its plans for the Phase 3 trial of trofinetide in Rett syndrome. As with Phases 1 and 2, the trial will be held in the US. In part, ACADIA stated that

We would like to share our plans for the Phase 3 study of trofinetide for Rett syndrome starting in the second half of 2019 which have now been confirmed. 

 ACADIA plans to conduct a three-month Phase 3, double-blind, randomized, placebo-controlled study to evaluate efficacy and safety of trofinetide and placebo in approximately 180 females ages 5 to 20 years with Rett syndrome. Half of the study participants will receive trofinetide and half will receive placebo

…………………………….  The Phase 3 study will be followed by an open label extension study in which all participants, including those on placebo in the Phase 3 study, will be eligible to receive trofinetide. In the open label extension study, all participants will be followed to evaluate long term tolerability and safety of trofinetide………………………. The ACADIA Rett Team“.
