Cyfendus: how long were the pivotal tox studies?

anthrax vaccine adsorbed, adjuvanted · TLR9 (CpG 7909 adjuvant)
Longest pivotal study
4 (adult rat repeat-dose study, full human dose on SD 1, 15, 29)
“The treatment-related effects were very similar in the single dose toxicity study as well as in the repeat dose toxicity study in adult (full human dose given on Study Day [SD] 1, 15, 29) and juvenile rats (1/5th of the human dose given on SD 21, 28, 35).”

Pivotal GLP studies
GLP rat studies, all IM: single-dose, repeat-dose, pre/postnatal DART and juvenile repeat-dose
“The applicant conducted a single-dose acute toxicity study, a repeat-dose safety toxicity study, a pre- and post-natal developmental and reproductive toxicity (DART) study, as well as a juvenile repeat-dose toxicology study. All these GLP-compliant toxicology studies were performed in rats, and animals were dosed with CYFENDUS via IM injection, the intended route for human use.”
