In the context of clinical research, LAR stands for Legally Authorized Representative. This term is critical in studies involving subjects who may not have the capacity to provide informed consent, such as minors or individuals with cognitive impairments. The LAR is a person who is authorized by law or regulation to make decisions on behalf of the participant regarding participation in the clinical trial. This ensures ethical standards are upheld and that individuals who cannot consent for themselves are still able to participate in research under appropriate oversight.

Understanding the role of a Legally Authorized Representative is essential for compliance with regulations and ethical guidelines in clinical research. It highlights the importance of ensuring that participants' rights and well-being are protected, even in cases where they cannot speak for themselves. This concept is integral to maintaining the integrity of the informed consent process within clinical studies.
