Carcinogenicity
Not conducted; acceptable under ICH S6
“The lack of carcinogenicity studies is considered acceptable based ICH S6 guidance.”

Reproductive & developmental
No fertility study; no reproductive organ effects in repeat-dose studies. Monkey ePPND: no teratogenicity; complete infant B-cell depletion, recovered within 6 months
“With regard to the offspring, a complete depletion of B-lymphocytes was observed at both tested dose-levels. B-lymphocyte counts and immunologic function (TDAR) in the infants returned to almost normal levels within 6 months following birth.”
Incorporated into 13- and 26-week monkey studies; no CNS, respiratory, blood pressure or ECG effects
“The potential effect of obinutuzumab on CNS, respiratory and cardiovascular systems was evaluated as part of the IV 26-week repeat-dose toxicity study in Cynomolgus monkeys (Report 1036190).”

hERG / QT
No hERG assay; no ECG rhythm abnormalities in the 26-week monkey study
“No rhythm abnormalities or qualitative ECG changes attributed to obinutuzumab were observed on Day 78 or 169 of the dosing phase or Day 254 of the recovery phase as part of the qualitative assessment of the ECGs.”
