I agree with the sentiments stated above as well. Overall you want to put a product out in the market that will in no way harm the patient and that can only be down through clinical or animal testing. There was just so much done in the past in regards to uninformed consent (Tuskegee syphilis study) or unjust clinical trials (Nuremberg trials) to not have stringent regulation over these trials. I do not believe these regulations will become any less strict anytime soon due to our history and the overall ethics of doing our due diligence as a society to ensure not only ensure the safety of the patients that will use these products but the current patients that partake in the clinical trials. That being said, I feel that if there is a need for it in the market, the proper funding will generally find its way to the right organization to make strides in innovation. This can be said for tragic diseases or cancers such as diabetes, pancreatic cancer, etc. There are numerous charitable organizations on the forefront of finding cures for these diseases through innovative technologies.
