Regarding the expense of clinical trials, it's important to note that the scientific results of a clinical trial are not protected by either patent or copyright. Pure research data cannot be restricted under any form of IP. Factual data without a creative element is explicitly exempted from both the patent and copyright system.

A published paper on the results of a trial may fall under copyright, but the factual observations and conclusions cannot be.

The "clinical trials are expensive" argument is incredibly disingenuous.
