Several critical elements define a cancer clinical trial:
- Randomization: Patients are randomly assigned to different treatment groups to reduce bias. - Blinding: Single or double-blinding minimizes bias by keeping patients and/or researchers unaware of treatment assignments. - Control Group: Comparing the new treatment to a placebo or standard therapy ensures that observed effects are due to the intervention. - Endpoints: Primary and secondary endpoints, such as overall survival and quality of life, measure treatment impact.
