Which statement is true regarding research initiated on or after January 21, 2019?

Research initiated on or after January 21, 2019, must comply with the revised Common Rule, which represents an update to the federal regulations that apply to research involving human subjects. The revised regulations introduced several changes aimed at enhancing protections for research participants, streamlining the review process, and adapting to modern research practices.

One major aspect of the revised Common Rule includes changes in categories of studies that qualify for expedited review and clearer guidelines for the informed consent process. The implementation of these updates means that any research that begins after the specified date must align with the new regulatory requirements tailored for better participant protection and research integrity.

In contrast, the other options suggest incorrect interpretations of the regulations. Research cannot be exempt from any regulations or choose to ignore the Common Rule entirely, as that would undermine the ethical standards established for the protection of human subjects. Furthermore, adherence to earlier versions of the Common Rule is only applicable to research that was initiated prior to the revised date and not to research starting on or after January 21, 2019. Thus, compliance with the revised Common Rule is a requirement for new research in the specified timeframe.
