What are Clinical Trials and Why Are They Important?
Clinical trials are essential for evaluating new cancer treatments in humans. They are conducted in phases:
1. Phase I: Tests the safety, dosage, and side effects of a new treatment in a small group of patients. 2. Phase II: Expands the study to a larger group to assess the treatment's efficacy and further evaluate its safety. 3. Phase III: Compares the new treatment with current standard treatments in a large group of patients to confirm its effectiveness and monitor side effects. 4. Phase IV: Conducted after the treatment has been approved for public use to gather additional information on its long-term effects and benefits.
