What types of clinical trials are available?

Clinical trials encompass various study types, including: 

• Prevention Trials: Explore methods to prevent diseases in individuals who have not had them or to prevent recurrence. 

• Treatment Trials: Test new treatments, drug combinations, or approaches to therapy. 

• Diagnostic Trials: Seek better tests or procedures for diagnosing specific conditions. 

• Screening Trials: Evaluate ways to detect diseases or health conditions. 

• Quality of Life Trials: Aim to improve comfort and life quality for individuals with chronic illnesses. 

Many trials compare a new product or therapy to existing treatments or placebos to determine effectiveness. Potential participants are informed beforehand if placebos are part of the study design.
