Check my plan vs. these
Genotoxicity
Not conducted for rAd-IFN; conducted for excipient Syn3 only (Ames and chromosome aberration, negative)
“Safety pharmacology, pharmacokinetics, toxicology, and genotoxicity studies were also conducted for the exicipient Syn3.”
✓ VerifiedFDA pharmacology/toxicology review, p. 2Source ↗
Carcinogenicity
Not conducted (not warranted by product characteristics, tox results, target population)
“Carcinogenicity and reproductive and developmental toxicity studies were not performed for rAd”
✓ VerifiedFDA pharmacology/toxicology review, p. 2Source ↗
Reproductive & developmental
Not conducted (not warranted by product characteristics, tox results, target population)
“Carcinogenicity and reproductive and developmental toxicity studies were not performed for rAd”
✓ VerifiedFDA pharmacology/toxicology review, p. 2Source ↗
Safety pharmacology
No dedicated vector study; excipient Syn3 in vitro hERG and in vivo CNS/CV/respiratory studies showed no risk up to 5 mg/kg
“Safety pharmacology studies do not indicate a risk for Syn3NODA in the in vivo studies evaluating CNS, cardiovascular and respiratory systems up to a concentration of 5 mg/kg.”
