Primary vs. Secondary Meds

One of the key questions for the FDA advisory panel to consider was whether the prescription fish oil was a primary preventer of cardiovascular disease or a secondary preventer. What’s the difference? Primary prevention of CVD would impact the disease and stop events before they occurred in the subjects taking the fish-oil medication. Secondary prevention would prevent additional CVD events from happening in those with established CVD.

If you were a type 2 diabetic with an additional risk for CVD such as obesity or being a smoker, taking the prescription fish oil with a statin would prevent a heart attack or stroke from happening; that’s primary prevention. Based on the Reduction of Cardiovascular Events with Icosa-pent Ethyl–Intervention Trial (REDUCE-IT) that didn’t happen, but it did prove to be a secondary preventer of additional cardiac events in those subjects in the study with established disease.

The question is whether the FDA will approve the prescription fish oil as a primary prevention or a secondary prevention pharmaceutical. The advisory panel seemed split on that count. The assumption by some was that there was disease present even though the event had yet to occur. Others said “prove it” by doing an actual clinical trial to examine that question. We’ll find out how the FDA decides later this year. As I mentioned yesterday, the financial implications are huge.

There are still some things to consider with the clinical trial, and I’ll cover that on Saturday.

What are you prepared to do today?
