How to Report Clinical Trial Results

Federal regulations and NIH policy require the Responsible Party to report results information for the clinical trial no later than one (1) year after the Primary Completion Date indicated in the registration record.

Results will be required if your study is registered as an Applicable Clinical Trial (ACT), Probable Applicable Clinical Trial (pACT), and/or is an NIH funded clinical trial.

Step 1: Review the Requirements for Reporting Results 

  • Review the Results Data Elements Definitions to understand what information is required.
  • Review the guidance for each of the four required results modules, which are tabular summaries of:
    • Participant Flow-the progress of participants through each stage of a study.
    • Baseline Characteristics-the data collected at the beginning of the study for all participants
    • Outcome Measures and Statistical Analyses-the pre-specified primary and secondary outcome measure values 
    • Adverse Events-all anticipated and unanticipated serious adverse events and unanticipated other adverse events exceeding a frequency threshold of five percent (5%) within any arm of the clinical trial.

Step 2:  Complete the Results Modules

Step 3:  Upload Supplemental Documentation

As part of the results reporting, the following documentation must be uploaded to the study's registration record in PDF format:

  • Full study protocol
  • Statistical analysis plan-if separate from the protocol.

Each document must be the most recent version reviewed by the IRB and include a cover page with the Official Title of the study, the NCT number (if available), and the date of the document.

The Responsible party may redact the following from the protocol prior to results submission:

  • Names, addresses, and other personally identifiable information, and/or
  • Trade secret and/or confidential commercial information

Step 4:  Release the Record

  • Preview, inspect, and submit the registration record. 
  • Verify in PRS that the Record Status is "Released." will not process the record unless it is released.

Step 5:  Address PRS Review Comments

Anytime the Responsible Party releases a record, PRS staff will review it for any apparent errors, deficiencies, and/or inconsistencies based on the PRS Review Criteria(link is external).  If PRS Staff identify potential issues with your record, they will add comments to your record.  Major comments must be corrected or addressed.  Comments identified as Advisory, should be addressed to improve clarity of the record. 

Once a record is released, the Responsible Party should:

  • Monitor the record for any PRS review comments.
  • Respond, in a timely fashion, to any communications from U-M oversight units (i.e. Regulatory Affairs, ORCR, etc.) regarding PRS review comments related to your study record.  
  • Make corrections in response to PRS review comments within 25 days.
  • Release the record for PRS review, once all corrections have been made.


The Responsible Party may submit a certification or extension request in to request a delay for reporting results.

  • Certification requests are allowable when the study is completed before a new drug or device is initially approved, licensed, or cleared by the FDA, or when the manufacturer/sponsor of the study is applying for approval/clearance of a new use of an already approved drug or device.  An approved certification request will delay the deadline to report results for up to two years from the certification date or for up to 30 days after the FDA approves, licenses, or clears the drug or device, whichever occurs first.  Only one certification delay is allowable per study.

  • Extension requests are allowable for a yet-to-be-defined list of "good cause."  The NIH reviews each request and grants reporting extensions.


It can take anywhere between 20-40 hours to submit results on  

No, trial results are not required for "non-applicable" trials that are registered on solely to comply with ICMJE policy.
