Investigator A conducts research on emphysema using biospecimens from human subjects. The consent form indicates that the research will focus exclusively on emphysema. Investigator B wishes to use the biospecimens for research on lung cancer. Can Investigator B use the specimens for cancer research without re-consent if the specimens are de-identified?
Yes, because research with biospecimens is minimal risk.
Yes, if the biospecimens are de-identified then the research is no longer considered human subjects research.
No, because it would be unethical to conduct research that is not consistent with the consent form the subjects originally signed.
No, the original research subjects must be re-consented for the cancer research.
The Correct Answer and Explanation is:
Correct Answer: Yes, if the biospecimens are de-identified then the research is no longer considered human subjects research.
Explanation:
According to the U.S. Department of Health and Human Services (HHS) regulations under the Common Rule (45 CFR 46), research involving biospecimens may not be considered human subjects research if the specimens are de-identified. De-identified means that all personally identifiable information (PII) has been removed such that the identities of the individuals cannot be readily ascertained by the investigator or linked to the specimens.
In this scenario, Investigator A originally obtained informed consent from participants to use biospecimens solely for research on emphysema. While this limits the scope of use under the consent, the crucial distinction arises when Investigator B wants to use these specimens for lung cancer research—a different disease focus.
If Investigator B uses de-identified specimens, this type of research is not considered human subjects research under the Common Rule, because it does not involve interaction or intervention with living individuals and does not involve identifiable private information. Since the biospecimens are stripped of identifiers and cannot be traced back to individual subjects, no re-consent is legally required, and the research can proceed ethically and legally under current federal guidelines.
However, it is important to recognize that this applies only when the specimens are truly de-identified. If there is any link—such as a code that allows the researcher to re-identify the subjects—then the research may still be considered human subjects research, and re-consent could be necessary.
Thus, while there may be ethical nuances surrounding participant expectations, current regulations clearly allow such research without re-consent if the biospecimens are fully de-identified, as they no longer fall under the scope of human subjects research.
