    • Any findings from other studies or animal testing that suggest a significant risk for human subjects, including reports of mutagenicity, teratogenicity, and carcinogenicity
  • Initial report: Any suspected adverse reaction that is both serious and unexpected must be reported to FDA within 15 calendar days of the Sponsor-Investigator's initial receipt of the information, otherwise referred to as a Suspected Unexpected Serious Adverse Reaction (SUSAR). Unexpected fatal or life-threatening SUSARs must be reported to FDA as soon as possible but no later than 7 calendar days following the sponsor's initial receipt of the information.
