**SUPPLEMENTARY INFORMATION:**
**I. Background**
FDA is announcing the availability of a guidance for industry entitled “Sponsor Responsibilities—Safety Reporting Requirements and Safety Assessment for Investigational New Drug Application and Bioavailability/Bioequivalence Studies.” The guidance provides recommendations to help sponsors and sponsor-investigators comply with the expedited safety reporting requirements for human drug and biological products that are being investigated (1) under an IND in accordance with § 312.32 (21 CFR 312.32) or (2) as part of a BA or BE study that is exempt from the IND requirements under § 320.31(d)(3) (21 CFR 320.31(d)(3)).
In the *Federal Register* of September 29, 2010 (75 FR 59935), FDA published a final rule amending the IND safety reporting requirements under § 312.32 and adding safety reporting requirements for persons conducting IND-exempt BA and BE studies under § 320.31. Compliance with these requirements increases the likelihood that submitted information will be interpretable and will meaningfully contribute to the developing safety profile of the investigational drug and improve the overall quality of safety reporting.
An effective systematic approach by sponsors to safety surveillance, coupled with focusing on IND safety reports for suspected adverse reactions that are both serious and unexpected, allows sponsors, FDA, participating investigators, and institutional review boards to focus on important safety issues and take actions needed to minimize the risks of participation in a clinical trial.
Following the publication of the final rule, FDA issued the guidance for industry and investigators entitled “Safety Reporting Requirements for Investigational New Drug Applications and Bioavailability/Bioequivalence Studies” (December 2012) (the 2012 final guidance) to help sponsors and investigators comply with safety reporting requirements for INDs and for BA/BE studies that meet the conditions for IND exemption under § 320.31(d)(3) (IND-exempt BA/BE studies). In 2015, FDA issued a draft guidance for industry entitled “Safety Assessment for Investigational New Drug Application Safety Reporting” (December 2015) (the 2015 draft guidance) that primarily focused on aggregate analysis of serious adverse events for reporting.
In the *Federal Register* of June 28, 2021 (86 FR 34020), FDA announced the draft guidance for industry entitled “Sponsor Responsibilities—Safety Reporting Requirements and Safety Assessment for Investigational New Drug Application and Bioavailability/Bioequivalence Studies” (the June 2021 draft guidance), which incorporated content from the 2012 final guidance and the 2015 draft guidance in terms of sponsors' responsibilities for safety reporting requirements for INDs and BA/BE studies. The 2015 draft guidance was withdrawn upon the publication of the June 2021 draft guidance. In September 2021, FDA issued the draft guidance for industry entitled “Investigator Responsibilities—Safety Reporting for Investigational Drugs and Devices” (the September 2021 draft guidance) to help clinical investigators comply with the safety reporting requirements of IND studies and investigational device exemption (IDE) studies. The September 2021 draft guidance incorporated content on investigator reporting under 21 CFR 312.64(b) from the 2012 final guidance.
In the *Federal Register* notice announcing the availability of the June 2021 draft guidance (86 FR 34020), FDA announced that when the June 2021 draft guidance and the September 2021 draft guidance were finalized, FDA planned to withdraw the 2012 final guidance because these guidances would replace the 2012 final guidance.
Elsewhere in this issue of the *Federal Register* , FDA also has announced the availability of a final guidance entitled “Investigator Responsibilities—Safety Reporting for Investigational Drugs and Devices.” Accordingly, FDA is withdrawing the 2012 final guidance at this time.
This guidance finalizes the June 2021 draft guidance. FDA considered comments received on the draft guidance as the guidance was finalized. Changes from the draft to the final guidance include revisions to the recommended approaches for aggregate analyses to reduce the need for unblinding to evaluate safety data; additional considerations for small programs and rare diseases; updated information for electronic submission of IND safety reports; and editorial changes for clarity.
This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on “Sponsor Responsibilities—Safety Reporting Requirements and Safety Assessment for Investigational New Drug Application and Bioavailability/Bioequivalence Studies.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.
