Supplemental Evidence and Data (SEADs) Guidelines

For those submitting supplemental evidence and data (SEADs) for systematic reviews, it is most helpful to the Effective Health Care (EHC) Program to provide:

  • A list of all completed studies your company has sponsored for this indication. In the list, indicate whether results are available on ClinicalTrials.gov along with the ClinicalTrials.gov trial number.
  • For completed studies that do not have results on ClinicalTrials.gov, a summary that includes the following elements: study number, study period, design, methodology, indication and diagnosis, proper use instructions, inclusion and exclusion criteria, primary and secondary outcomes, baseline characteristics, number of patients screened/eligible/enrolled/lost to follow-up/withdrawn/analyzed, and effectiveness/efficacy and safety results.
  • A list of ongoing studies your company has sponsored for this indication. In the list, please provide the ClinicalTrials.gov trial number or, if the trial is not registered, the protocol for the study including a study number, the study period, design, methodology, indication and diagnosis, proper use instructions, inclusion and exclusion criteria, and primary and secondary outcomes.
  • A cover letter that includes a notation of whether the above studies constitute ALL Phase II and above clinical trials sponsored by your company for this indication and an index outlining the relevant information in each submitted file.

Your contribution is very beneficial to the EHC Program. The contents of all submissions will be made available to the public upon request. Materials submitted must be publicly available or can be made public. Materials that are considered confidential; marketing materials; pharmacoeconomic, pharmacokinetic or pharmacodynamic studies; study types not included in the review; or information on indications not included in the review cannot be used by the EHC Program.

This is a voluntary request for information and all costs for complying with this request must be borne by the submitter.

For further information or assistance, please contact epc@ahrq.hhs.gov.

Public reporting burden for this collection of information is estimated to average 15 minutes per response, the estimated time required to complete the survey. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to: AHRQ Reports Clearance Officer Attention: PRA, Paperwork Reduction Project (0935-0231) AHRQ, 5600 Fishers Lane, #07W41A, Rockville, MD 20857.

Section 944 (c) of the Public Health Service Act [42 U.S.C. 299c 3(c)]requires that information collected for research conducted or supported by AHRQ that identifies individuals or establishments be used only for the purpose for which it was supplied unless they consent to the use of the information for another purpose.
