In China, the protection of subjects just started in 1990s, and everything is "immature". There is no special drug trial law in China, but only a "Quality Management Standard for Drug Clinical Trials" to regulate the drug trial behavior in China, which is not mandatory, and there are loopholes in the informed consent form signed between drug testers and hospitals before drug clinical trials.
In practice, many clinical trial units do not respect or even violate the informed consent right of subjects, conceal the drug risks, make unclear explanations or only reach oral informed consent.
Operation mode of drug tester:
Usually, the recruitment of healthy subjects is completed by posting advertisements on the campus of medical colleges or posting recruitment notices on the university website. The most popular students are male medical college students, because they have a certain understanding of pharmacological knowledge, can communicate well with doctors, don't worry too much about adverse reactions, and have better physical fitness.
Animal experiments and toxicity tests have been carried out before the drug enters clinical trials, and in principle, there is no side effect on healthy drug testers. The most likely side effect of this drug trial is "occasional gastrointestinal discomfort".
