Attention: New applications for IRB review on or after January 21, 2019 must meet the requirements of the revised Common Rule. See the 2018 Common Rule Consent Requirements on this page >

Rooted in the principle of respect for persons, informed consent is not just a form but a process that begins with subject recruitment, progresses to the consent discussion and review of the consent form, and continues through the duration of a subject's participation in the study and beyond. During a study, all communication (including both oral and written) with research participants is part of the process of informed consent.

The IRB must approve not only all written documents shared with research participants, but also the plans for approach, recruitment, and other interactions during the study. Unless the IRB grants a waiver of informed consent, investigators are responsible for obtaining legally effective informed consent prospectively from each research participant, or participant's legally authorized representative, as required by Fred Hutch IRB and the regulations for the protection of human research subjects. Refer to 45 CFR 46.116 and 46.117 for federally funded research, and 21 CFR 50 Subpart B for FDA-regulated research.


Obtaining informed consent is a basic ethical obligation for researchers. The process of consent should ensure that potential subjects are provided with information about the research project that is understandable and permits the subject to make an informed and voluntary decision about whether or not to participate. The amount of information and the manner of presentation is generally related to the complexity and risk involved in the research study. While the initial process is prospective and takes place prior to any research activity, consent should also be an ongoing educational interaction between the investigator and the research subject that continues throughout the study and even beyond, as pertinent information comes to light that should be shared with the former participant.

The consent process is not an exercise in persuasion. If an investigator has a relationship with potential subjects (physician-patient, instructor-student, employer-employee), care should be taken to avoid recruitment methods that may be coercive due to the special relationship between parties.

Consent is also a legal concept. Only legally competent adults can give legally effective informed consent. Legal competency and capacity to consent is determined by the law of the state in which the research is conducted. For research studies approved by the Fred Hutch IRB the presiding law is the law of the jurisdiction in which the research is conducted. That law will also control when determining who is capable of acting as the legal representative for a research participant. For assistance in determining who may act as the "legally authorized representative" or "LAR" for a prospective research participant, refer to the IRB Policy 2.25 on the Identification and Use of Legally Authorized Representatives or contact the Institutional Review Office or General Counsel.


Children and those individuals who are not competent to provide consent should be given the opportunity to assent to participate in the research project. Assent is a knowledgeable agreement to participate in the project. Adequate provisions should be made for soliciting the independent, non-coerced assent from children or cognitively impaired persons who are capable of a knowledgeable agreement. In general, the IRB recommends that children age seven and older, and most cognitively impaired adults, be given the opportunity to assent.

In cases where assent is obtained from a cognitively impaired subject, permission must also be obtained from a legally authorized representative. In studies involving children, the parent(s) or legal guardian must provide consent.

If the person from whom assent is sought refuses to participate in the research, the investigator should respect the decision of the child or cognitively impaired adult, even when the parent/guardian or legally authorized representative gives permission. The IRB may make an exception to affirmative assent in studies of children with life-threatening illnesses who are eligible for research treatment protocols. Alternatively, if the person from whom assent is sought agrees to participate, the person may not be enrolled if the parent/guardian or legally authorized representative does not give permission. In cases where questions arise as to who may act as a legally authorized representative, it is recommended that you seek assistance from the Fred Hutch General Counsel.

The assent form is used when the investigator recruits subjects who, by age or circumstance, are not able to give legally effective informed consent. When legally effective informed consent cannot be obtained, the investigator should obtain the assent of the child or cognitively impaired adult subject. This form documents the child's or cognitively impaired adult subject's knowledgeable agreement, or assent, to participate in a research project. For studies involving children, the IRB recommends that an assent form be used with children who are in the 7-13 age range, but it may also be used when teenagers are being recruited to enhance their comprehension if the study involves complicated procedures.

2018 Common Rule Requirements


The following apply in addition to the other requirements listed on this page to HHS-regulated research approved on or after January 21, 2019, to HHS-regulated studies that were previously approved under the pre-2018 requirements that are now undergoing de novo review, and to new research approved on or after January 21, 2019 that is both FDA- and HHS-regulated.

Note: Fred Hutch IRB does not review or allow Broad Consent.

New Basic Element of Consent

9. One of the following statements about any research that involves the collection of identifiable private information or identifiable biospecimens:

  • A statement that identifiers might be removed from the identifiable private information or identifiable biospecimens and that, after such removal, the information or biospecimens could be used for future research studies or distributed to another investigator for future research studies without additional informed consent from the participant or the legally authorized representative, if this might be a possibility; or
  • A statement that the participant’s information or biospecimens collected as part of the research, even if identifiers are removed, will not be used or distributed for future research studies.
New Additional Elements of Consent

7. A statement that the participant’s biospecimens (even if identifiers are removed) may be used for commercial profit and whether the participant will or will not share in this commercial profit;

8. A statement regarding whether clinically relevant research results, including individual research results, will be disclosed to participants, and if so, under what conditions; and

9. For research involving biospecimens, whether the research will (if known) or might include whole genome sequencing (i.e., sequencing of a human germline or somatic specimen with the intent to generate the genome or exome sequence of that specimen).


New General Requirements
  • The prospective participant or the LAR must be provided with the information that a reasonable person would want to have in order to make an informed decision about whether to participate, and an opportunity to discuss that information.
  • Informed consent must begin with a concise and focused presentation of the key information that is most likely to assist a prospective participant or LAR in understanding the reasons why one might or might not want to participate in the research. This part of the informed consent must be organized and presented in a way that facilitates comprehension.
  • Informed consent as a whole must present information in sufficient detail relating to the research, and must be organized and presented in a way that does not merely provide lists of isolated facts, but rather facilitates the prospective participant’s or LAR’s understanding of the reasons why one might or might not want to participate.

  3. UW policy does not allow the HIPAA authorization to be embedded within a consent form. The stand-alone UW HIPAA Authorization form must be used.

Documentation of Informed Consent

Required by 45 CFR 46.117 or 21 CFR 50.27.

The purpose of a consent form is to provide subjects with a written source of information for future reference and to document the fact that the initial process of informed consent occurred prior to the subject's participation. The form generally serves as a basis for the initial presentation of the study to the potential subject. With few exceptions, informed consent is documented by using the written consent document approved by the IRB and signed and dated by the subject or the subject's legally authorized representative at the time of consent. A copy of the consent form should be given to the subject. Unless the investigator has been granted a waiver of documentation of consent, the subject's signature on a consent form is required prior to beginning any study procedures.

When using an assent form, the child or cognitively impaired adult should sign the assent form, to indicate knowledgeable agreement (assent) to participate. In addition, the parent/guardian or legally authorized representative should sign the full consent form to document his/her permission for the child or cognitively impaired adult to participate.

A signature line for a PI or researcher is required only for research that needs to comply with International Conference on Harmonization guidelines. Pre-signed consent forms should never be used.
