Is the CRC responsible for subject safety?

• A. Yes, under PI supervision
• B. No
• C. Yes, independently
• D. Only during enrollment

Answer: (A)

Subject safety in a clinical trial is primarily the responsibility of the Principal Investigator. The Clinical Research Coordinator supports safety work, but always under the PI’s supervision and authority. What this means in practice is that the CRC helps monitor participants, collect and document safety data, and ensure timely reporting of adverse events to the PI, sponsor, and IRB. The CRC also helps verify informed consent remains up to date and that safety procedures outlined in the protocol are followed. However, the final decisions about safety actions—such as changes to monitoring, treatment, or whether to discontinue a participant—are made by the PI within the study’s oversight framework. Safety obligations are continuous, not limited to enrollment. Adverse events can occur at any time, so ongoing safety oversight sits with the PI, with the CRC acting under supervision to support and implement those safety processes.
