Clinical trials are research studies designed to evaluate the safety, effectiveness, and outcomes of medical treatments, devices, or interventions in human participants. They follow structured protocols that help researchers collect reliable data, assess results, and ensure patient safety and ethical compliance.
There are different types of clinical trials, ranging from early-phase studies focused on safety and dosage to late-phase trials that evaluate effectiveness across larger populations. Each phase plays a critical role in advancing medical knowledge and bringing new therapies to patients.
