Clinical Trials
Clinical trials are prospective scientific studies that evaluate the safety, efficacy, and dosage of medical interventions in human participants under controlled conditions.
Overview
In areas such as new drug development, studies typically advance through four sequential phases, progressing from initial safety and dosage assessments in small groups to comparative efficacy trials against standard treatments and post-approval surveillance. Methodologies including randomization, blinding, and control groups are systematically employed to minimize bias and support valid statistical inference.
Why it matters
Clinical trials provide the empirical foundation for translating biomedical hypotheses into evidence-based clinical practice and regulatory drug approvals.
