Success would be a major leap forward for both Ischemix and the treatment of ischemic-reperfusion injuries, for which there are no FDA-approved therapies despite many previous attempts. The closely held company—funded primarily by its chairman, and its medical director—has enough money to pay for the mid-stage clinical and not much else beyond that, according to DuFresne.

The clinical trial is expected enroll 200 to 220 patients, many of whom are undergoing surgeries to unblock their arteries and implant stents to restore blood flow, according to DuFresne.
