A » Clinical trials are structured in phases to assess the safety and efficacy of medical interventions. Phase I focuses on safety and dosage, involving a small group of participants. Phase II expands to evaluate efficacy and side effects, while Phase III involves larger populations for confirmation and comparison to existing treatments. Phase IV occurs post-approval, monitoring long-term effects and ensuring continued safety. Each phase is critical for advancing medical knowledge and patient care.

A »Clinical trials are organized in phases to test new treatments. Phase 1 focuses on safety by administering the treatment to a small group. Phase 2 expands the group to assess efficacy and side effects. Phase 3 involves larger groups to confirm effectiveness and monitor adverse reactions, often leading to regulatory approval. Finally, Phase 4 continues post-approval to gather long-term data. This structured approach ensures patient safety and treatment efficacy.
