Conducted: Ames, chromosomal aberration in mammalian cells, mouse micronucleus; all negative
“Avacincaptad pegol was negative for genotoxicity based on a standard battery of studies including the bacterial reverse mutation assay, chromosomal aberration in mammalian cells and in vivo mouse bone marrow micronucleus assays.”

Carcinogenicity
Not conducted (waiver accepted; low systemic exposure, C5-inhibitor class experience)
“Carcinogenicity No studies were conducted. The Applicant submitted a justification to support a waiver request not to conduct the carcinogenicity studies”

Reproductive & developmental
EFD studies in rat and rabbit (IV, NOAEL 1.2 mg/kg/day); FEED and PPND waived
“In the embryofetal development (EFD) toxicity studies in rats and rabbits, there was no avacincaptad pegol-related adverse effects on any measured maternal or fetal parameter at doses up to 1.2 mg/kg/day (NOAEL).”

“The NOAEL for cardiovascular and respiratory findings in this study was the high dose, 100 mg/kg.”

Carcinogenicity model
Not conducted: waiver based on mechanism of action, route, literature, class effects and existing data
“The Applicant justification to omit the conduct of nonclinical carcinogenicity studies is based on avacincaptad pegol mechanism of action, route of administration, a supportive literature review, an analysis of pharmacological class effects, and nonclinical and clinical data collected to date.”
✓ VerifiedFDA pharmacology/toxicology review, p. 69Source ↗
Carcinogenicity timing
Not required: carcinogenicity waiver accepted on weight of evidence
“The Applicant submitted a justification not to conduct carcinogenicity, fertility/early embryonic development, and pre-/postnatal development studies. The Pharmacology/Toxicology team concluded that the weight of evidence supports that the studies are not necessary for the intended dosing regimen and indication.”

hERG / QT
Negative: hERG IC50 >100 µM; minimal QTc risk
“The IC50 was not determined but considered to be > 100 μM, supporting minimal risk for QTc prolongation.”
