Mice treated with the drug had much smaller dead-cell areas in their artery plaques—almost half as big—which might mean their plaques are less likely to break open.
Scientific Claim
In apolipoprotein E-deficient mice on a high-fat high-cholesterol diet, treatment with MPE-298 is associated with a 44% reduction in necrotic core area in the aortic sinus compared to vehicle controls, indicating a potential link to improved plaque composition.
Original Statement
“MPE-298 caused a modest 17% (p < 0.05) reduction of lesion areas (Figure 1F) and significantly reduced necrosis by 44% (p < 0.01) compared to that of vehicle-treated mice (Figure 1G).”

Assessment Explanation
The authors state MPE-298 'reduced necrosis,' implying causation, but the study design (mouse model, no blinding confirmation) only supports association.
More Accurate Statement
“In apolipoprotein E-deficient mice on a high-fat high-cholesterol diet, treatment with MPE-298 is associated with a 44% reduction in necrotic core area in the aortic sinus compared to vehicle controls.”
Evidence from Studies
Supporting (1)
The study found that a new drug called MPE-298 made dangerous fatty buildups in the arteries of mice more stable and less likely to rupture — which is exactly what the claim says it does.
