Amgen Files Repatha sBLA on CV Outcomes Data
Amgen has submitted a supplemental BLA for Repatha (evolocumab), a PCSK9 inhibitor, based on a cardiovascular outcomes study (FOURIER) which the company says showed that “maximally reducing low-density lipoprotein cholesterol (LDL-C) levels with Repatha, beyond what is possible with the current best therapy alone, leads to a further reduction in major cardiovascular events, including heart attacks, strokes and coronary revascularizations.”
The study demonstrated that “adding Repatha to optimized statin therapy resulted in a statistically significant 20% (p<0.001) reduction in hard major adverse cardiovascular events (MACE) represented in the composite (secondary) endpoint of time to first heart attack, stroke or cardiovascular death,” Amgen says. The study also found a statistically significant 15% reduction (p<0.001) in the risk of the extended MACE composite (primary) endpoint, which included hospitalization for unstable angina, coronary revascularization, heart attack, stroke or cardiovascular death.
Additionally, Amgen notes that the magnitude of risk reduction in both the primary and secondary composite endpoints increased over time, with the “robust benefit starting as early as six months and accruing through the median 2.2 years of the study.”
