Clinical trials typically follow a structured process divided into phases: 1. Phase I: Tests safety and dosage in a small group of healthy volunteers. 2. Phase II: Assesses efficacy and side effects in a larger patient group. 3. Phase III: Confirms effectiveness, monitors side effects, and compares it to commonly used treatments in a large patient group. 4. Phase IV: Conducted after FDA approval to monitor long-term effects and efficacy.
Each phase requires meticulous planning, ethical considerations, and rigorous oversight, often involving nurses in various capacities.
