Clinical Research

The primary objective of clinical research is to generate scientific evidence regarding the safety and efficacy of medical interventions, treatments, or procedures.

Clinical trials typically consist of four phases: Phase I focuses on safety and dosage, Phase II evaluates efficacy and side effects, Phase III further assesses effectiveness and monitors adverse reactions, and Phase IV involves post-market surveillance.

The key ethical principles include respect for participant autonomy, beneficence (maximizing benefits and minimizing harm), justice (fair distribution of benefits and burdens), and ensuring informed consent.

Clinical research studies are regulated by government agencies such as the Food and Drug Administration (FDA) in the United States and the European Medicines Agency (EMA) in the European Union, which set guidelines and requirements for conducting research involving human subjects.

Placebo-controlled trials help researchers evaluate the true effectiveness of a new treatment by comparing it to a placebo, thereby reducing bias and ensuring that any observed effects are attributable to the treatment itself rather than other factors.
