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

olezarsen · APOC3 (ASO)
Genotoxicity
Conducted; negative (Ames, chromosomal aberration, mouse micronucleus)
“Olezarsen was not mutagenic in vitro or in vivo.”
✓ VerifiedFDA integrated review, p. 104Source ↗
Carcinogenicity
Not conducted with olezarsen; relied on volanesorsen lifetime mouse/rat studies (tumors of uncertain relevance)
“Carcinogenicity studies were not conducted with olezarsen, but lifetime carcinogenicity studies were conducted for the active unconjugated ASO, volanesorsen, in both mice and rats.”
✓ VerifiedFDA integrated review, p. 104Source ↗
Reproductive & developmental
Mouse FEED study with olezarsen; EFD and PPND bridged from volanesorsen (mice/rabbits)
“The Agency agreed that embryofetal development and pre-/postnatal development evaluations conducted with the unconjugated active ASO component of olezarsen in mice and/or rabbits were adequate to support a marketing application.”
✓ VerifiedFDA integrated review, p. 200Source ↗
Safety pharmacology
Stand-alone in vitro hERG and single ascending-dose SC monkey CV/respiratory/CNS study; no relevant effects
“Other than a transient increase in heart rate at the highest dose at 360 minutes, there were no effects on cardiovascular, respiratory, or central nervous system functioning observed.”
✓ VerifiedFDA integrated review, p. 213Source ↗
