Responsibilities of the PI include:
- Supervising the conduct of the study in compliance with the signed investigator statement, investigational plan, and applicable regulations.
- Protection of the rights, safety, and welfare of study subjects.
- Ensuring IRB review, approval, and appropriate reporting.
- Informed consent is adequately obtained.
- Control of drugs under investigation.
- Adequate and appropriate record keeping and retention.
- Completion and submission of investigator reports to the sponsor that include progress reports, safety reports, final report, and any financial disclosures.
