According to the press release, the company decided to push the drug into late-stage testing after discussing its midstage results with regulatory authorities in the U.S. and EU. Last year, tirasemtiv failed to meet its primary endpoint of improving ALS symptoms, along with some secondary endpoints such as respiratory function, in a large midstage trial.
