It's not just the healthcare system, also the pharma. Trials for more precise targeting of cancer medicines don't get sponsorship from the maker of the medicine

It's not just the healthcare system, also the pharma. Trials for more precise targeting of cancer medicines don't get sponsorship from the maker of the medicine because if it succeeds they would sell less. Trials for new uses of medicines don't go through if the medicine is close to patent expiry. It makes sense as they are for profit corps but it sucks
