Redemplo: genotox, carcinogenicity and repro: done or skipped?

plozasiran · APOC3 (siRNA)
Genotoxicity
Conducted: Ames, in vitro chromosomal aberration (TK6), in vivo mouse micronucleus; not genotoxic
“Plozasiran was not genotoxic when tested in the in vitro bacterial mutation (Ames) assay, in vitro chromosomal aberration assay in cultured TK6 lymphoblastoid cells, and in vivo micronucleus assay in mice.”
✓ VerifiedFDA integrated review, p. 103Source ↗
Carcinogenicity
Conducted: 26-week Tg.rasH2 mouse negative; 2-year rat study ongoing
“In the 26-week study in Tg.rasH2 mice, administration of plozasiran by the SC route Q8W up to 120 mg/kg (~50-fold clinical dose, based on AUC) did not increase the incidence of tumors in male or female mice.”

Reproductive & developmental
Conducted in rat: fertility (NOAEL 50 mg/kg), EFD (NOAEL 60 mg/kg), PPND (pup survival reduced at 24 mg/kg and above); no rabbit
“The NOAEL for male and female fertility was 50 mg/kg (19-fold the human dose, based on BSA).”

Safety pharmacology
Standalone monkey CV study (single SC dose up to 300 mg/kg); hERG not warranted
“Plozasiran had no adverse effect on cardiovascular function in conscious cynomolgus monkeys following a single dose of SC injection up to 300 mg/kg.”
