Clinical trials are systematic research studies that assess the safety and efficacy of medical interventions like drugs or treatments in human subjects. These trials follow a structured protocol, progressing through phases to gather data on the intervention's effectiveness, potential side effects, and overall impact. Participants, often volunteers, contribute to advancing medical knowledge, and rigorous ethical and regulatory standards ensure their safety and rights are protected. The outcomes of clinical trials inform medical decision-making, shape treatment guidelines, and contribute to advancements in healthcare.
