Changing an approved study at Capella: modifications, amendments, and what must wait for approval

What is the rule, and where does it come from?

The federal rule is in 45 CFR 46.108(a)(3)(iii): institutions must ensure "that investigators will conduct the research activity in accordance with the terms of the IRB approval until any proposed changes have been reviewed and approved by the IRB, except when necessary to eliminate apparent immediate hazards to the subject." Capella's Policy 3.03.01 restates it as a researcher responsibility: "Researchers must obtain approval from the IRB before modifying their approved research procedures, sites, or forms." Capella's doctoral-support FAQ on amendments is blunter still: "No changes may be implemented to your study until you receive a response from the IRB stating that your proposed changes have been approved."

Capella's SOPs list the failure modes this rule exists to prevent. Among the examples of non-compliance are "changes were made to the study without IRB approval" and "researcher changed study materials and/or study procedures without IRB approval." The SOPs also make the point that the application is the approved document: information in a research plan or SMART form that does not appear on the IRB application "is considered not approved by the IRB." So a modification is not a courtesy notice; it is how the approved study becomes the study you are actually running.

Which changes need the Modification Form, and which need only an email?

Capella's SOPs draw one explicit line. "Grammar fixes or corrections of typos in participant facing materials (consent forms, recruitment materials) do not require IRB review and approval," but you must email the IRB Office with a summary of the proposed changes before using the revised materials; the Office then tells you whether a Modification Form is needed and acknowledges by email if it is not. The SOPs add that IRB staff "reserves discretion to determine what constitutes a minor change." Everything else is a modification. The table below is our reading of Capella's published guidance; the board decides the level of review for each request.

Capella's amendment FAQ adds a scope note worth reading twice: changes "that alter the risk determination for a study, or introduce a new conflict of interest, or involve significant changes to previous procedures or materials may require additional review." And the SOPs say that for a major modification — "change in recruitment strategy, data collection methods, study methodology" — the IRB "may require the researcher to submit a new application and that the entire study be re-reviewed." We do not predict which way a given request will go; we prepare it so that either answer is quick.

What can happen before approval, and what never can?

Two narrow cases. The first is the emergency change. Capella's SOPs say that when "a change may be necessary to eliminate apparent immediate hazards to the research participants," the researcher makes the change and then informs the IRB promptly — the SOPs state the window — and the IRB reviews the change afterward. This is for a participant's safety in the moment, not for convenience.

The second is the one-time exception. Capella's SOPs distinguish a modification (a permanent change to the protocol) from an exception (a temporary deviation from it). The examples given are a single site requiring a minor change to recruitment procedures, or enrolling one participant who does not meet inclusion criteria. Exceptions are requested in writing to the IRB Office before implementation; staff may approve those that "do not increase risk to participants or alter the study design," and anything that may increase risk goes to the IRB. An exception does not change your protocol for the next participant; if you want the change to be permanent, it is a modification.

Everything else waits. That includes starting at a new site because the letter "is on its way," using a revised consent form because the change "is only clearer," and adding a question to the interview guide because a participant raised something interesting. Capella's SOPs also state two facts that catch people: modifications "do not extend the original IRB approval date," and "a modification does not replace continuing review." Continuing review and study closure at Capella covers that second calendar.

Who else has to know?

Three parties besides the IRB. Your mentor, always — Capella's guidance has the mentor coordinating any review of changes with the school. Your research site, depending on the change: the SOPs say administrative modifications that do not affect risk require written notification to the site, which may be an exchange of email, while substantial modifications that "increase risk to participants, significantly alter study procedures, or impact study design" require updated permission letters; cosmetic changes need neither. And participants, if the board says so: when reviewing a modification the IRB "must consider whether information about those modifications might relate to participants' willingness to continue" and whether to provide it to them. If you are changing recording, confidentiality, or what is being asked, expect to be asked how current participants will be told.

One special case: a study that received a not-human-subjects-research designation has no approved protocol to modify. Capella's FAQ says those researchers should contact the IRB Office for guidance rather than submit a Modification Form, because the change may alter the designation itself.

How do I file a modification in IRBManager?

Capella's 2020 Modification Form guidance is a literal click path, and the order matters.

1. Log in to IRBManager. Under My Projects on your home page, click your study ID. The guidance stresses: "You MUST click on your Project ID BEFORE you click on Start xForm," or the Modification Form will not appear.
2. On the study page, under Actions, choose Start xForm, then choose IRB Modification Form.
3. Complete the form using the guidance written into the form itself: what is changing, why, and which documents change.
4. Attach a revised research plan, SMART form, or proposal that aligns with the change — the guidance recommends it for every modification, and the SOPs require it with school approval when methodology changes.
5. Attach every other revised material — recruitment text, consent, interview questions, site letters — under "Upload revised documents required for this modification," using Add Attachments. Send tracked and clean copies with version stamps; our piece on writing a revision response explains the same discipline.
6. Enter your IRBManager password, click Next, then Submit. The form is not in review until that last click.
7. Do nothing new until the written approval arrives. Then do exactly what the approval says, and nothing the modification did not request.

Capella's SOPs note that doctoral researchers may not submit modification requests unless registered — Capella ties research activity to active enrollment in the dissertation or capstone course — so check your registration status before you plan a change across a quarter break.

What to do next

If you are weighing a change, send us the approval letter, the approved application, and a one-paragraph description of what you want to change and why. We read it free and tell you whether it reads as an email, a modification, an exception, or something that sends the research plan back through the school — and what the file needs to carry either way. Request the free review. If the change is going ahead, we prepare the Modification Form, the revised documents, the site notification or permission, and every reply until approval, under the same terms as the original application: the study stays yours and the board's decision is its own. How it works and the FAQ explain what that looks like from your side; the step-by-step Capella IRB process shows where modifications sit in the larger sequence.
