SPAs are different:
=500 mg/dL (MARINE): It’s always approved based on surrogate endpoints, since „It's hard to imagine an event-driven pancreatitis trial for super-high triglycerides.” (Dr.Hiatt / AdCom)
=200 mg/dL and <500 mg/dL (ANCHOR & REDUCE-IT): Both evaluate the same high risk patient population, however ANCHOR was to improve atherosclerotic markers, including triglycerides, non-HDL-C, Apo B, and hsCRP without having a detrimental effect on LDL cholesterol (surrogate endpoints), meanwhile REDUCE-IT is to demonstrate Vascepa efficacy to reduce cardiovascular events. It is an event-driven trial.
FDA rescinded the ANCHOR’s SPA as improvement of these markers is not enough to determine the efficiency.
I do not say that the FDA will not try to null the R-IT trial, however they could not ignore / null the result since it’s events.
