TSI is leading development of a next-generation therapy to change the treatment paradigm for ischemic stroke and heart attack.

TSI’s treatment regimen, developed by world leaders in thrombolysis, was successfully studied in a Phase I safety trial, and will be studied in two Phase II confirmatory clinical trials.
