Hello. Unfortunately your question is incomplete, which does not allow it to be answered. However, from the context of your question it is possible to assume that you want to know which of the two doctors is using the correct approach. If this is the case, we can say that Dr. Jayson is correct, as he is offering his patients a scientifically proven drug that will not harm patients, but will help them to treat any problem. Dr. Yuri can only try the new drug on patients if they agree to participate in this research, otherwise it would be unethical and dangerous.
