Carcinogenicity
Not conducted; weight-of-evidence: IL-23 neutralization not expected to increase cancer risk
“In general, an overview of the published literature supports that neutralization of IL-23 would not be expected to increase cancer risk, but rather IL-23 increases tumor incidence and promotes tumor growth and progression.”

Reproductive & developmental
Monkey ePPND (300 mg/kg): embryo/fetal loss 26.7% vs 6.7% in controls, within historical control range
“However, incidences of embryo/fetal loss were higher in the treated groups compared to control (6.7% [1 of 15] in controls vs 26.7% [4 of 15] at 300 mg/kg) but were within the range of historical control data.”

Safety pharmacology
Incorporated into 4-week monkey study (IV up to 100 mg/kg, SC up to 30 mg/kg); no cardiovascular, CNS or respiratory findings
“No adverse cardiovascular, central nervous system, or respiratory findings were observed in monkeys as part of the 4-week toxicology study administered via both IV (doses up to 100 mg/kg) and SC (doses up to 30 mg/kg) routes.”

Carcinogenicity model
Not conducted; weight-of-evidence assessment, rodents not pharmacologically relevant
“Conventional rodent carcinogenicity studies were not conducted for the evaluation of the carcinogenic potential of mirikizumab as rodents are not a pharmacologically relevant species.”

Carcinogenicity timing
Waived: CDER ECAC concurred a 2-year rodent study is not needed
“Concurrence has been received from the Executive Carcinogenicity Assessment Committee of CDER that a 2-year rodent carcinogenicity study is not needed.”
