Not conducted (ICH S6(R1)); no pharmacological activity in mice and rats
“In accordance with ICH Guideline S6(R1), conventional carcinogenicity studies (i.e., rodent bioassays) have not been conducted with MLN0002 to assess its carcinogenic potential as it lacks pharmacological activity in mice and rats.”

Reproductive & developmental
Rabbit embryo-fetal and monkey pre-/postnatal development studies: no adverse effects
“MLN0002 did not cause any adverse effect on embryofetal development in rabbits or on pre- and postnatal development in monkeys.”

Safety pharmacology
Telemetered cynomolgus monkey cardiovascular study: no effect on ECG, arterial blood pressure or heart rate
“In a cardiovascular safety pharmacology study in telemetered Cynomolgus monkeys, MLN0002 did not show any effect on ECG parameters, arterial blood pressure or heart rate.”

Genotox: Ames
Not conducted (humanized monoclonal antibody, ICH S6(R1))
“Genotoxicity studies were not conducted as vedolizumab is a humanized monoclonal antibody and so are not required in-line with ICH Guideline S6(R1).”
Not conducted (no rodent pharmacological activity); in vitro Act-1 tumor-cell growth study instead
“Conventional carcinogenicity studies (i.e., rodent bioassays) have not been conducted with MLN0002 to assess its carcinogenic potential as it lacks pharmacological activity in mice and rats. However, carcinogenic potential of Act-1 (murine homologue of MLN0002) was assessed in an in vitro study using human tumor cells that expressed”

Carcinogenicity timing
Not required (rodents not pharmacologically responsive; ICH S6(R1))
“Conventional carcinogenicity risk assessment studies (ie, rodent bioassays) have not been conducted with vedolizumab as rodents are not pharmacologically responsive to this mAb. This is consistent with ICH Guideline S6(R1).”
No effect on ECG, arterial blood pressure or heart rate in telemetered cynomolgus monkeys
“In a cardiovascular safety pharmacology study in telemetered Cynomolgus monkeys, MLN0002 did not show any effect on ECG parameters, arterial blood pressure or heart rate.”
