IRB Submissions

When is IRB Approval Required? 

If your project involves "research" and "human subjects" as defined by 45 CFR 46, you must submit an application to the Case Western Reserve University Institutional Review Board (IRB) for approval prior to the recruitment of study participants and the collection of data. Human research for student theses and dissertations always requires prior IRB approval. Data collected before approval is obtained cannot be used for research.

Who can be the Principal Investigator of an IRB Protocol submission? 

The principal investigator (PI) of all protocol submissions submitted to the IRB must be a CWRU faculty member. 

The definition of a CWRU faculty member includes: 

  • CWRU Board of Trustees appointed faculty, who is eligible for benefits 
  • CWRU Board of Trustees appointed faculty at an affiliate hospital* with research funding managed by the university 
  • CWRU board appointed faculty or clinical faculty at an affiliate hospital* conducting research to benefit CWRU students 

Some exceptions can be made for individuals who meet the following criteria: 

  • postdoctoral scholar or fellow with independent funding 
  • research scientist, senior research associate or research associate; CWRU benefits eligible, with approval from department dean/chair or vice president of unit 
  • other staff positions, with approval from department dean/chair or vice president of unit

* Affiliate hospitals are: Cleveland Clinic, The MetroHealth System, University Hospitals, Louis Stokes Cleveland Veterans Affairs Medical Center

When to submit a protocol submission to the CWRU IRB versus an affiliate hospital IRB?

Some CWRU faculty members also have an appointment at one of CWRU’s hospital affiliates. 

  • If the faculty member is conducting research that will involve hospital patients, their data, and/or a hospital facility or equipment, the affiliated hospital IRB will be the IRB of record.
  • If the CWRU faculty member is conducting research under their role as a CWRU faculty member and not recruiting hospital patients or using their data, then the CWRU IRB can be the IRB of record.

For questions or a consultation: Please contact the CWRU IRB at or one of the hospital-affiliated IRBs:

Getting Started

If you aren’t sure if your research activity requires IRB review, please contact to learn whether IRB approval is required.

Request a SpartaIRB account

If you do not have one already, request a SpartaIRB account and make sure that the PI and all study team members have an active Continuing Research Education Credit (CREC) certificate. Additional training, such as Good Clinical Practices (GCP), may be required for certain research.

Access SpartaIRB to create a study

In SpartaIRB, prepare a protocol application by creating a new study and complete the information in the SmartForm.

Select the correct protocol template by determining the type of research you would like to conduct:

  • Biomedical
  • Social, educational, behavioral
  • Chart review
  • Biospecimens

Keep in mind:

  • IRB submissions must be complete and review-ready when they are first submitted to the IRB.  Poorly prepared submissions negatively impact the review and approval times of well-prepared submissions by diverting significant time and resources to a small fraction of submissions that do not meet our basic standards for review.

Upload the required documents

The following documents are required to support your research study and must be uploaded in SpartaIRB:

  • Informed Consent Document
  • Questionnaires
  • Recruitment materials
  • Letters of Cooperation
  • Approval letters from other committees/departments that are required to support the research activities in your protocol submission

Complete and submit the protocol 

In SpartaIRB, complete the protocol submission

  • Submit it for Department Scientific Review.
  • Once this review is approved, the PI is required to submit the application to the CWRU IRB.
  • Respond to the CWRU IRB Office to answer any pre-review clarifications requested.
  • Respond to the CWRU IRB Office to answer any clarifications/modifications required to secure approval.

Processing and Timeline Information

The CWRU IRB's portfolio includes over 1,200 active protocols and averages 110 protocol submissions each month. In addition to the review and approval of new studies, the IRB is responsible for review and approval of modifications, continuing reviews, study closures and the reliant review process of studies that have multiple sites and are required to rely on one IRB of record (either the CWRU IRB or an external IRB). We are committed to performing a thorough and timely review of submitted protocols.

The current guidelines to submit IRB submissions are posted below as a general guide only. Submissions that are incomplete or do not adhere to IRB submission guidelines will require additional time for review and approval. 

It is strongly recommended to submit at least 8-12 weeks in advance of the proposed start date of the study whenever practicable to avoid delays in the onset of human subjects research.

  • IRB approval is dependent on meeting the regulatory criteria, institutional policies and procedures, and the cooperation of the investigator(s) in responding to the IRB's requests for clarifications and modifications promptly.
  • IRB approval will be delayed if all study team members are not CREC certified and do not have a Conflict of Interests disclosure form on file.
  • Completion of Ancillary Committee Reviews and meeting additional FDA requirements, if applicable, can delay IRB approval.
  • NIH Grants or Submissions Requiring Just-In-Time Review

To ensure that the NIH's timelines are met, the IRB Office encourages investigators to start working on the study submission in the SpartaIRB system as soon as a fundable score is received.

Studies are reviewed in the order in which they are received. When investigators request that the IRB prioritize a review, it affects our ability to perform a timely review of those protocols already in the queue. This may cause a delay in the start of human subjects research of your colleagues.

Investigators who believe that their submission requires immediate processing due to delays, which adversely affect study subjects, should contact the executive director for research compliance, and provide justification and a description of the specific circumstances.
