The IND application undergoes a thorough review, ensuring the safety and feasibility of the planned human trials.
Upon approval, Phase 1, 2, and 3 clinical trials ensue, each with specific goals. Phase 1 primarily focuses on drug safety and dosage determination in a small group of healthy volunteers. Successful completion advances the candidate to larger, more diverse populations in Phase 2, where efficacy is assessed alongside further safety monitoring. If the data are favorable, the FDA reviews the results from these trials, evaluating the overall benefit-risk profile before granting marketing authorization for GLP-1 drugs. This meticulous process guarantees that only safe and effective medications reach the market, benefiting patients worldwide.
Clinical Trials and Their Impact on GLP-1 Drug Approvals
Clinical trials have played a pivotal role in shaping the regulatory landscape for GLP-1 agonists, driving their eventual approval for medical use.
