MITOCARE STUDY Multicenter, randomized, double-blind, placebo controlled study to assess safety and efficacy of TRO40303 for reduction of reperfusion injury in STEMI patients undergoing primary PCI Rationale: TRO40303 has been shown to reduce infarct size by 50% in rat and mouse models, and to improve LVEF at 24h and 1 month in these models. It has also shown protective effects on human isolated cells.Mechanism: The mitochondrial permeability transition pore is believed to be a promising target for preventing reperfusion injury.TRO40303 has shown to inhibit the opening of this transition pore. Scope and Enrolment Period of the Study:October 2011-September 201310 interventional sites in Denmark, France, Norway, Sweden. MitoCare – HEALTH-F2-2010-261034
Study Design TRO40303 Dose 6 mg /kg, N = 90 Drug/placebo given as IV bolus by large peripheral vein, during PCI, just before balloon inflation.

Baseline Characteristics (Median (min-max), N patients or % per group) Anterior/Posterior Infarction: 33/47 31/51 • Baseline characteristics were well-balanced between the two groups except for age which was higher in the TRO40303 group Procedural Characteristics Pain-to-balloon time: 180 min (mean) Door-to-balloon time: 38 min (mean)
Procedural Characteristics Procedural characteristics were well-balanced between the two groups except for unsuccessful reperfusion (Median (min-max), N patients or % per group) MitoCare – HEALTH-F2-2010-261034

MITOCARE - Conclusions • The MITOCARE trial did not show any protective effect of TRO40303 compared to placebo in preventing reperfusion injury in STEMI patients treated with primary PCI • A high standard of care accounted for the relatively small infarct size after primary PCI, leaving little room for improvement • There were more adjudicated events in the TRO40303-group than in the placebo-group • This could partly be explained by the difference in unsuccessful reperfusion between the groups (12.1% in the TRO40303-group versus 6.3% in the placebo-group) • These results combined with the many failures in the field raise a provocative issue: whether reperfusion injury occurs at all in man, and, if it does, whether this type of injury really accounts for a significant part of the remaining infarct MitoCare – HEALTH-F2-2010-261034
