Beg to differ Boiler

"Clinical trials involving new drugs are commonly classified into four phases. Each phase of the drug approval process is treated as a separate clinical trial. The drug-development process will normally proceed through all four phases over many years. If the drug successfully passes through Phases 0, 1, 2, and 3, it will usually be approved by the national regulatory authority for use in the general population."

Phase 0: Pharmacodynamics and Pharmacokinetics

Phase 1: Screening for safety

Phase 2: Establishing the efficacy of the drug, usually against a placebo

Phase 3: Final confirmation of safety and efficacy

Phase 4: Sentry studies during sales
