Clinical trials play a fundamental role in the medical field by validating the practical application of treatments. This process involves rigorous testing of new drugs, therapies, and medical devices directly in human participants, which allows researchers to gather vital data about their safety, efficacy, and overall impact on health.

Through clinical trials, the medical community can assess how well a treatment works under real-world conditions and examine its effects across diverse populations. This evidence is critical for determining whether a new treatment should be approved for widespread use. Moreover, the findings from these trials contribute to the broader understanding of diseases and can lead to improvements in treatment protocols.

While other aspects of drug development, such as theoretical knowledge, preclinical research, and animal testing, are essential, they do not replace the need for clinical trials. They provide foundational information but lack the real-world insights that only human trials can offer.
