Approvals are good for one year.
If your study is continuing beyond a year, you will need to submit a renewal of the human subject protocol. It is very important that you submit your renewal paperwork well in advance of the expiration date if you wish to continue the study. The principal investigator should receive a blue renewal form in the mail about 8 weeks before the expiration date. If you do not receive the renewal form, you need to call the OHRP and request it. Please note that it is the investigator's responsibility to submit a renewal on time and obtain the renewal form if necessary.
