Резюме	Clinical trial registration is the prospective documentation of a trial's key information (hypothesis, design, population, outcomes) in a public registry before enrollment begins or results are known. In 2005, the World Health Organization established the requirement that all clinical trials be registered in an internationally recognized registry before participant enrollment. The International Committee of Medical Journal Editors (ICMJE) made registration a condition for publication in major medical journals in 2005, updated in 2015. Primary registries include ClinicalTrials.gov (U.S.), ISRCTN (UK), EudraCT (EU), and others operating under WHO oversight. Registration serves to prevent selective outcome reporting, reduce publication bias, and enhance research transparency.	Vulnerable populations are groups with limited capacity to protect themselves due to age, cognitive ability, institutional dependency, or social circumstances. Regulatory frameworks in the U.S. (45 CFR 46 Subparts B, C, D) and internationally identify specific vulnerable populations—children, prisoners, pregnant women, cognitively impaired individuals—and mandate additional ethical protections beyond standard informed consent. These protections include obtaining informed consent from surrogate decision-makers (parents, guardians), additional assurances of minimal risk, and enhanced monitoring for safety. Research ethics committees apply heightened scrutiny to studies involving vulnerable populations and may deny approval if special protections are inadequate.
