Are you ready to understand how new medicines move from the lab to real patients? In this detailed tutorial, you’ll discover the phases of clinical research explained step-by-step — from the first-in-human studies to real-world post-marketing surveillance. Clinical research is at the heart of every medical breakthrough. Before a drug reaches patients, it passes through four critical phases of clinical trials, each designed to answer a specific question about safety, efficacy, and long-term performance. In this video, you’ll learn: ✅ Phase I: Is it safe? — How researchers test a new compound in humans for the first time. ✅ Phase II: Does it work in patients? — Proof of concept and dose-finding studies that measure early efficacy. ✅ Phase III: Is it better than what we have? — Large, global trials that provide the evidence needed for regulatory approval. ✅ Phase IV: What happens after approval? — Real-world data collection,...
