PHASE II CLINICAL TRIALS First Phase II is Proof of Concept (PoC) Followed by dose-ranging trials Objective is to propose dose(s) for Phase III design Moving doses down to MinED If dose-range is not found in Phase II, it will be too expensive in later Phases 8. A Phase 0 clinical trial is a new idea from the US Food and Drug Administration and the Pharmaceutical Research and Manufacturers of America (PhRMA) that both organizations say they hope will streamline the process of drug development. If the agent is new to clinical testing, this must be based on animal studies. In phase 1 clinical trials, the safety, tolerability and toxicity of the drug at different doses is tested in a small number of healthy volunteers.
