I'm sure it take decades of research and FDA approval costing, on average, nearly a billion dollars to bring any new drug to market. I see the article states she is in an immunotherapy study so I'm guessing that Capitalism is funding this. Venture capitalists buy stocks in bioresearch firms. They then short and use options to manage their risks as the majority of studies will fail to achieve good results.
Socialist systems are not capable of doing this type of cutting edge research. However, I have heard some people say that Europeans are the FDA's favorite lab rat.
Clinical trials in Europe is big business
For the most part, drugs are tested on the expected patient population. So if you want to have a drug approved in Europe, you have to test it there. Even if it is already tested in the US.
I am not so sure about human clinical trials but when I worked for a pharmaceutical (granted in finance not on the science side) I saw a lot of invoices for animal trials from companies in located Europe, many in the Netherlands – mostly monkey and beagles. I am not sure why that was or if that has changed since the early 2000’s. We did have a small animal lab (small in both the size of the lab and as in the size of the animals – mice and rats) in our facility in Baltimore.
