Arimoclomol in Sporadic Inclusion Body Myositis - Open Label Extension Trial

This was planned to be a 40-month open-label extension trial of the 20-month randomized, double-blind, placebo-controlled IBM4809 trial. The open-label trial was terminated early by the sponsor as a consequence of the results of IBM4809 which did not meet any of its efficacy endpoints. Therefore, the actual average duration of open-label treatment was approximately 28 weeks.
