Phase 2 Clinical Trials
摘要
Drug development is lengthy and costly, with few candidates progressing from Phase 1 to Phase 2 trials. Phase 1 assesses dosing and side effects, while Phase 2 involves more participants, providing broader data on dosing, safety, and some efficacy. Phase 2 acts as a bridge to large-scale Phase 3 trials, which determine the drug’s final outcome. This chapter provides an overview of Phase 2 clinical trials.
