Abstract

Clinical trials represent the cornerstone of drug development, providing critical evidence to determine the safety, efficacy, and quality of new pharmaceutical products. The design of these trials is pivotal, as a poorly conceived protocol can lead to inefficiencies, inconclusive results, or regulatory setbacks. Best practices for clinical trial design emphasize methodological rigor, patient-centered approaches, and adherence to ethical and regulatory standards. This article explores the essential components of successful clinical trial design, including trial methodologies, key findings from research studies, and the role of regulatory compliance in ensuring reliable outcomes and public trust in the drug approval process.
