Before any drug or therapy can be applied to humans it must be rigorously tested through a process called clinical translation.
Clinical translation involves taking a treatment through several stages to test for safety and efficacy before it can be approved by medical authorities such as the FDA (US Food and Drugs Administration) or EMA (European Medicines Agency) to be applied to humans. See the following diagram which summarises how the process (in the case of the FDA) works:
