Supplemental guidance: R25 - Education Projects
For Fogarty-supported R25 "Education Projects" that support trainees conducting mentored human subject studies:
- Enter each trainee human subjects research project study record separately.
- Enter whether the study is exempt. Determine if the study is exempt using the Exempt Human Subjects Research Infographic .
- Respond to the clinical trial questions.
- Respond “No” to the Phase III clinical trial question.
- Respond “No” to the Food and Drug Administration Amendments Act FDAAA question.
- Add or upload an inclusion enrollment report for each study record.
Supplemental guidance: D43 - International Research Training Grants and U2R - International Research Training Cooperative Agreements
For Fogarty-supported D43 "International Research Training Grants" and U2R “International Research Training Cooperative Agreements" that support trainees conducting human subject (HS) studies:
- Enter at least one study record for the non-clinical trial studies for the training program:
- Inclusion Enrollment Records (IERs) are not required for non-clinical trial trainee studies.
- Phase III questions must be marked “No.”
- Food and Drug Administration Amendments Act (FDAAA) question must be marked “No.”
- If a trainee is conducting an independent clinical trial, a separate individual record must be created for this study:
- All the required information must be completed.
- An Inclusion Enrollment Record (IER) must be uploaded into HSS.
- Phase III question must be answered.
- Food and Drug Administration Amendments Act (FDAAA) question must be answered.
