StemRIM Inc. announced the commencement, from April 10, 2023, of a global Phase II trial of Redasemtide in patients with acute ischemic stroke. This developmental milestone was achieved after receiving approval from PMDA, in response to a clinical trial plan submitted by Shionogi & Co. Ltd. on March 27, 2023.

Originally, a global Phase III trial was planned, but, for the purpose of dose setting, a global Phase II trial was chosen instead.
