“The ansuvimab-zykl nonclinical safety studies included a good laboratory practice (GLP) 4 week, intravenous, repeat-dose toxicology study in rhesus monkeys”
Rhesus monkey is the lethal EBOV challenge model used for proof of concept
“The activity of ansuvimab-zykl was evaluated in three in vivo proof-of-concept studies in which rhesus monkeys were challenged with uniformly lethal doses of Kikwit 8U EBOV (1000 pfu).”
Rhesus monkey only (GLP 4-week IV repeat-dose study)
“The ansuvimab-zykl nonclinical safety studies included a good laboratory practice (GLP) 4 week, intravenous, repeat-dose toxicology study in rhesus monkeys”
Not conducted: not generally required for biologics against exogenous targets (ICH S6(R1))
“Dedicated reproductive toxicology studies have not been conducted with ansuvimab-zykl. In accordance with ICH S6(R1), reproductive toxicology studies are generally not required for biologics to exogenous targets.”
“In accordance with ICH S1A and ICH S6(R1), carcinogenicity studies are not required as ansuvimab-zykl will be administered as a single intravenous (IV) infusion.”
No surrogate used; ansuvimab-zykl itself tested in rhesus monkeys
