Typically, clinical trials involve multiple phases, each building upon the previous one. Phase I focuses on initial safety assessments and dosage determination in a small group of healthy volunteers or patients with the target condition. Phase II expands the study to larger groups to further assess effectiveness and identify potential side effects. In Phase III, the drug is tested in even larger patient populations across multiple centers to gather more comprehensive data on its benefits and risks.
The data collected from these trials are crucial for regulatory bodies like the FDA (U.S. Food and Drug Administration) or EMA (European Medicines Agency), which are responsible for granting marketing approvals. These agencies review the trial results, including information on drug efficacy, safety profiles, manufacturing processes, and quality control measures, to determine whether the benefits outweigh any potential risks. This meticulous process ensures that GLP-1 drugs reaching the market meet stringent standards, providing patients with safe and effective treatments for diabetes and other related conditions.
