Not conducted (ICH S6(R1), ICH S9); no increased carcinogenic risk expected from mechanism
“Carcinogenicity studies have not been conducted in accordance with ICH S6(R1) and ICH S9. Furthermore, due to its mechanism of action, atezolizumab is not expected to be associated with an increased carcinogenic risk.”

Reproductive & developmental
No dedicated studies; chronic monkey study: irregular menstrual cycles and no new corpora lutea at high dose
“Reproductive and developmental toxicity studies have not been conducted with atezolizumab. However, in the chronic toxicity study in sexually mature monkeys, atezolizumab treatment at the high-dose resulted in irregular menstrual cycles and a lack of newly formed corpora lutea in the ovaries.”
Incorporated into 8- and 26-week monkey studies (CNS, cardiovascular telemetry, respiratory)
“Central nervous system, cardiovascular (telemetry and/or surface leads), and respiratory safety pharmacology parameters were evaluated as part of the 8- and 26-week GLP Cynomolgus monkey toxicology studies (Studies 08-1148 and 13-3278).”
Not conducted (ICH S6(R1), ICH S9); no increased carcinogenic risk expected from mechanism
“Carcinogenicity studies have not been conducted in accordance with ICH S6(R1) and ICH S9. Furthermore, due to its mechanism of action, atezolizumab is not expected to be associated with an increased carcinogenic risk.”
No hERG assay; no atezolizumab-related ECG findings in monkey toxicology studies
“No atezolizumab-related electrocardiographic findings were observed; all electrocardiograms evaluated in this study were qualitatively and quantitatively within normal limits.”
