Medical Product Discovery &
Development
• The clinical development of pharmaceutical products has become a global undertaking
• Sponsors conduct clinical trials globally to use data as support for a new drug application (NDA)/biologics license application (BLA)
• Regardless of where trials are conducted, FDA’s determinations on medical product approval depend on the demonstration of effectiveness and safety
![Page 10: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/10.jpg)

History of Foreign Clinical Trial Data Submission
• It was uncommon for a Sponsor to submit foreign clinical trial data prior to the 1962 Kefauver-Harrison Amendments
• The 1975 provision codified in 21CFR312.120 permits submission of foreign clinical trial data not conducted under an IND
![Page 11: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/11.jpg)

FDA’S GOOD CLINICAL PRACTICE (GCP) EXPECTATIONS
![Page 15: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/15.jpg)
15
Conducting Clinical Trials• Studies using investigational product that has not been approved by
the FDA or for indications not in the approved labeling may require filing an investigational new drug (IND) application with the FDA – If a study meets specific regulatory exemption criteria, then an IND
may not be needed
• When a study is conducted under an IND but is located outside of the United States, the study must meet all relevant FDA regulations as if it were being conducted within the United States
• Sponsors are not required to conduct their studies outside of the US under an IND in order to use them as support for an NDA/BLA.
![Page 16: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/16.jpg)
16
Study Outside U.S Not Conducted Under an IND
• FDA accepts a well-designed, well-conducted, non-IND foreign study as support for marketing approval, under 21 CFR 312.120.
• The sponsor must ensure that the study complies with the requirements in 21 CFR 312.120 to use it as support for marketing approval.
![Page 17: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/17.jpg)
17
Clinical Trials Not Conducted Under An IND: Acceptance of Clinical Data
• FDA accepts foreign clinical data from studies not conducted under an IND if the following conditions are met:
1. Study was conducted in accordance with Good Clinical Practice (GCP)
2. FDA is able to validate the data from the study through an onsite inspection
![Page 18: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/18.jpg)

SITE SELECTION FOR INSPECTION
![Page 23: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/23.jpg)
23
Risk-Based Site Selection for Inspection
• FDA uses risk based approach to identify and target sites for inspection (greater impact on public health or likely to have problems)
• The approach takes into account the risk of the application (new molecular entity [NME] vs non NME), site level attributes (comparative performance indicators) and study level attributes
• Using innovative strategies & tools to identify sites for clinical inspection
Site Selection Tool for Inspection
![Page 24: International Clinical Trials: GCP Perspective › sites › cersi.umd.edu › files › D2S12-Ayalew-v1.pdfRisk-Based Site Selection for Inspection • FDA uses risk based approach](https://reader033.fdocuments.in/reader033/viewer/2022060507/5f21c77ecee62b308f407d1c/html5/thumbnails/24.jpg)

Factors to Consider: When to InspectInspection approach is similar for domestic and foreign sites
Importance of the study
• Relevance to labeling/NDA/BLA• Contribution/size/outliers/concern of scientific
misconduct, protocol violations, study discontinuations
• Statistical impact of data from the site
History of the clinical investigator• Frequency and prior classification(s)• Findings of previous inspection(s)
Data Contribution • Domestic versus international
IQVIA CONFIDENTIAL

25
International Inspections
• Clinical sites likely to be audited when:
– only foreign data are submitted to support an application
– insufficient domestic data
– domestic and foreign data show conflicting results pertinent to decision-making
– there is a serious issue to resolve (e.g., suspicion of fraud, scientific misconduct, significant human subject protection violations)

Post Inspection Letters to non U.S. Investigators
• Observations on Form FDA 483 are based on regulations.• FDA does not have regulatory authority outside of the U.S.• FDA’s ability to inspect a non-US entity comes from submission of the
data.• When observations indicate serous breach of GCPs, FDA issues
administrative correspondence letters to investigators outside of the U.S. However the letters do not not hold the same meaning as one issued to an investigator in the U.S.
