Conducting clinical trials in children involves several phases, similar to adult trials, but with additional ethical and safety considerations. These phases include:
1. Phase I: Small group trials to assess safety and dosage. 2. Phase II: Larger group trials to test efficacy and further evaluate safety. 3. Phase III: Large-scale trials to confirm effectiveness, monitor side effects, and compare with commonly used treatments. 4. Phase IV: Post-marketing studies to gather additional information after the treatment has been approved.
